Portobello Mushroom Wellington Recipes

Steps:

• Wipe the mushrooms with a piece of damp paper towel to remove dirt and grit; twist out and discard the stalks. Place in a large roasting tray with the garlic, thyme, Marsala, oil and salt and pepper. Rub each mushroom with the garlicky oil and cover the tray with tin foil. Place in an oven heated to 180°C (350°F) for 15 minutes, until the mushrooms have reduced in size and are soft throughout. Remove the foil, drain away the cooking liquid and set the tray on a cool surface while you prepare the rest of the Wellington.
• For the onions, melt the butter with the oil in a medium frying pan over a medium heat. When all the butter has melted, add the onions with a pinch of salt and cook, stirring regularly, until the onions turn soft and translucent. Add the thyme, garlic and Marsala to the pan and continue to cook for a further 15 minutes, stirring every 2 minutes until the onions are golden and caramelized all over. Remove the onions from the pan to a plate lined with paper towels to drain away the excess oil and butter. Leave to cool completely.
• Next, make the pancakes. Whisk the eggs with the flour in a large mixing bowl, then slowly pour in the milk, whisking all the time until no lumps are visible. Add the chopped rosemary and season with salt and pepper. Cover with plastic wrap and set aside for 10 minutes until bubbles appear on the surface of the batter.
• Warm a 26 cm. (10 in.) non-stick frying pan with a splash of sunflower oil over a medium-high heat. Pour half a ladle of the pancake batter into the pan and swirl to evenly coat the base.
• Cook each pancake for a minute on each side, until lightly golden, then flip and cook the other side. The mixture should produce 6-8 thin pancakes.
• Cook the spinach for a minute with a pinch of salt and a grating of nutmeg in a frying pan until bright green and just wilted. Squeeze out as much moisture as you can through a sieve, then dry on kitchen paper.
• Lay out a 30cm (12 in.) piece of plastic wrap on a clean work surface, then lay 4 cooled pancakes alongside each other on the plastic wrap (you can use any extra when making the Wellington), ensuring a generous amount of overlap so that there is a continuous length down the middle of the plastic wrap. Brush the pancake all over with some of the egg yolk, then arrange the spinach down the middle of the pancakes, leaving a couple of centimeters at each end without spinach.
• Place the mushrooms on top of the spinach, placing one on top of the other, giving four layers of two down the center. Top the mushrooms with the caramelized onion mixture, then use the plastic wrap to lift the pancake over the filling on either side. Fold over the ends and continue rolling until you have a tight cylinder shape. If there are any gaps, use the extra pancakes to patch up, brushing with egg yolk as you go. Wrap the pancake tightly with plastic wrap and chill in the fridge for 20 minutes.
• Roll out the sheet of puff pastry and brush with egg yolk. Remove the chilled pancake cylinder from the fridge and unwrap the cling film. Place in the middle of the puff pastry sheet and fold the pastry over the filled pancake to encase it completely. Crimp the sides of the pastry and brush with egg yolk all over. Scatter over the black onion seeds and cook in an oven heated to 180°C (350°F) for 25-30 minutes, until dark golden all over.
• While the Wellington is cooking, make the sauce. Heat the olive oil in a small saucepan over a medium heat, then add the shallots and garlic with a pinch of salt and cook for 5 minutes, until soft and translucent. Add the thyme and dry sherry and bring to the boil. Reduce for 3 minutes, then add the stock. Continue to cook until the liquid has reduced by half, then add the heavy cream and turn the heat to low. Cook for 5 minutes, then season with salt and pepper.
• Serve the Wellington with the tarragon cream sauce in a jug for pouring over and steamed broccolini and kale on the side.

Steps:

• Preheat oven to 375 degree F.
• Using a spoon, scrape gills from interior of mushrooms.
• Generously drizzle olive oil over mushrooms and season with salt and pepper.
• Place mushrooms on baking sheet and bake until tender (8-10 mins). Set aside to cool.
• Cut puff pastry sheet into four equal squares.
• Place a mushroom in the center of pastry, layer with roasted pepper, basil leaves and goat cheese. Finish with a second portobello mushroom.
• Fold centers of pastry around filling, bringing them together at top. Be sure to enclose entirely.
• Place on parchment-lined baking sheet with folded side down.
• Brush top of Wellington with egg wash.
• Bake in oven for 12-15 mins, until pastry is golden.

Steps:

• Make the Wellington: Preheat the oven to 350˚ F. Heat 1 tablespoon olive oil in a medium skillet over medium heat. Stir in the onion to coat. Spread evenly in the pan, reduce the heat to low and cook, stirring occasionally, until caramelized, 12 to 20 minutes. Set aside.
• Spread the butternut squash on a parchment-lined baking sheet. Drizzle with 1 tablespoon olive oil and gently toss to coat. Sprinkle with salt and lay 5 thyme sprigs on top. Bake until the squash is tender and starting to caramelize, about 15 minutes.
• Gently pull apart the maitake mushrooms into small pieces and place in a medium bowl. Add 2 tablespoons olive oil, season with salt and gently toss to coat. Spread in an even layer on a separate parchment-lined baking sheet. Top with 5 thyme sprigs and 5 rosemary sprigs and bake 15 minutes. When the vegetables are cool to the touch, gently remove the herb sprigs and discard.
• Toast the hazelnuts on a separate baking sheet until fragrant, 5 to 8 minutes. (Be careful not to burn the nuts.)
• Heat 1 teaspoon olive oil in a medium skillet over medium heat. Add the garlic and cook, stirring, until softened. Add the spinach, season with salt and cook, stirring frequently, until wilted, 3 to 4 minutes. Let cool slightly, then gently squeeze out any liquid over the sink.
• In the same skillet, heat the remaining 1 teaspoon olive oil over medium heat. Add the portobello mushroom caps and sauté until they soften and release their liquid, 7 to 8 minutes. Transfer to paper towels to drain. Gently press to remove any excess liquid.
• Chop the leaves from the remaining 2 thyme sprigs and 2 rosemary sprigs. In a medium bowl, mix the caramelized onions, butternut squash, spinach, hazelnuts, maitakes, chopped herbs and 1 teaspoon each salt and pepper. Mix well with a spoon or your hands.
• Preheat the oven to 400˚ F. Unfold the puff pastry on the counter. Spread the vegetable mixture on the pastry in an even layer, leaving a 2-inch border on one short side. (You will have some of the vegetable mixture left over.) On the short side opposite the clean border, arrange the portobello caps dome-side up in a line, about 2 inches in from the edge, overlapping if necessary. Top the mushrooms with the rest of the vegetable mixture.
• Gently roll up the puff pastry tightly, starting at the side with the portobellos and pushing in any filling that falls out. Place seam-side down on a parchment-lined baking sheet. Gently score a crosshatch pattern into the top of the pastry with a sharp knife; brush with the vegan egg wash. Bake until golden brown, 15 to 20 minutes.
• Meanwhile, make the gravy: Heat the olive oil in a medium saucepan over medium heat. Add the shallots, reduce the heat to medium low and cook, stirring, until they start to caramelize, 8 to 10 minutes. Stir in the flour and cook, stirring, until light golden brown, about 4 minutes. Slowly add the vegetable stock and red wine, whisking constantly so that no lumps remain. Increase the heat to medium high and cook, stirring, until the gravy thickens, 2 to 3 minutes. Add the tamari and sugar and season with salt and pepper. Slice the Wellington and serve with the gravy.

Steps:

• Pre-heat oven to 375 degrees F. Lightly brush the portobello mushrooms with olive oil and dust lightly with kosher salt. Bake the portobello mushrooms for 15 minutes cap side up and 10 minutes cap side down. Once done baking place mushrooms on a paper towel so all the extra moisture will be absorbed. Set aside. In a large skillet, saute 1 shallot and 2 minced cloves of garlic in olive oil until translucent. Add the baby spinach leaves. Stir to coat the spinach and lightly salt and pepper to taste, once the spinach looks like it is wilting, add the balsamic vinegar. Once the leaves are wilted, remove from skillet and place contents into a bowl and set aside. In the same skillet, melt 2 tablespoons of butter and saute 2 minced shallots and 2 minced garlic cloves. After about 1 minute, add in the chopped mushrooms and lightly season with salt and pepper and a pinch of crushed red pepper. Continue to saute the mushrooms on medium heat until all of the moisture is cooked out and the mushrooms are soft. Remove from heat, add the mushrooms to the spinach mixture. Mix together and let cool. Once mixture is cooled toss in the bread crumbs, toasted pine nuts and Gruyere cheese. Mix well. On a lightly floured surface, roll out one sheet of the puff pastry. Cut into 4 equal pieces (if you have really large portobello mushrooms then you might need to use the extra sheet of puff pastry). Equally fill each portobello mushroom cap with the spinach and mushroom mixture. Place one piece of puff pastry over a filled portobello mushroom. Gently turn the mushroom over so the puff pastry is now on your working surface and the mushroom is upside down. Lightly brush the egg wash around the outer edges of the puff pastry. Place the opposite corners of the puff pastry to wrap around the portobello and then bring the other two corners up. Gently bring the sides up to completely cover the mushroom. Once all is secure, place the seamed side down onto a parchment paper lined baking sheet. Lightly brush the top of the wellington with a little bit of egg wash, lightly score the top and dust a little bit of salt and pepper on top. Bake the wellingtons for about 25-30 minutes or until the puff pastry is nice and golden brown. Serve immediately. **Notes:** If you want to omit the portobello mushroom then just fill each square with equal parts crimini mushroom/spinach and Gruyere filling. Brush the egg wash on the outer parameters of the puff pastry and fold opposite corners together to make a triangle pocket. Bake as directed and serve with a green salad.

Steps:

• Wipe the portobello mushrooms clean using barely moistened paper towels. Remove the stems, then slice off the excess mushroom rim that curls over the gills. (You are making sure the stem side has a flat surface so it will sear properly.) Reserve the stems and scraps for use in Step 2. Brush the portobello mushroom caps on both sides with 3 tablespoons olive oil and season generously with salt and pepper. Heat 2 tablespoons olive oil in a large (12-inch) nonstick skillet over medium-high and cook the mushrooms, gill-side down, until caramelized, 4 to 5 minutes, then flip and cook until softened, about 4 more minutes. Transfer to a wire rack, gill-side down, to cool.
• Prepare the mushroom filling: Separate and reserve any mushroom stems. Roughly chop about two-thirds of the mixed mushrooms, then working in batches, transfer the roughly chopped mushrooms to a food processor and pulse until chopped into small pieces. (They should range from 1/4 inch to 1/2 inch in size.) Transfer the chopped mushrooms to a large bowl. By hand, finely chop the remaining mixed mushrooms and stems and the reserved portobello mushroom stems and trimmings into 1/4-inch pieces; add them to the large bowl. (Chopping most of the mixed mushrooms in the food processor will save you some time, but you'll want to chop some by hand for texture.)
• Prepare an ice bath in a large bowl. (You'll use this to quickly cool the cooked mushrooms in Step 4. If preparing in advance, you can simply let the mixture cool to room temperature, then refrigerate.) Wipe out the skillet. Working in two batches, warm 1/4 cup olive oil over medium-high heat. Add about half the mushrooms, shallots, garlic and rosemary, and season lightly with salt and generously with pepper. (You'll add soy sauce later, so avoid overseasoning at this stage.) Cook, stirring occasionally, until caramelized and tender, about 10 minutes. Transfer to a medium bowl and repeat with the remaining 1/4 cup oil and the remaining mushrooms, shallots, garlic and rosemary.
• Once the second batch of chopped mushrooms is cooked and caramelized, return the first batch to the skillet. Add the port, soy sauce and thyme leaves and cook over medium-high, stirring occasionally, until the liquid evaporates, 3 to 5 minutes. (If using balsamic vinegar instead of port, reduce the cook time to 1 to 2 minutes.) Transfer the mushroom mixture back to the medium bowl and stir in the walnuts. Set the bowl over the prepared ice bath to cool, stirring occasionally, at least 20 minutes.
• Prepare the cider-caramelized onions: Wipe out the skillet, then melt the butter over medium heat. Add the onions, sprinkle with the sugar, salt and pepper, and cook, stirring occasionally, until starting to soften, about 5 minutes. Add the cider and cook, stirring every few minutes, until the liquid evaporates and the onions are caramelized, about 15 minutes. Stir in the vinegar, if using, then transfer to a bowl to cool.
• Heat the oven to 400 degrees. Place a large piece of parchment paper on your work surface and lightly dust it with flour. Unfold your thawed puff pastry and set it on the parchment. Using a lightly floured rolling pin, roll the pastry out into a 13-by-16-inch rectangle. Transfer the parchment paper and puff pastry to a large sheet pan. Rotate the sheet pan, if needed, so that one of the 16-inch sides is closest to you. Arrange half the cooked mushroom mixture in a strip in the center of the puff pastry (it should be about 4-by-10 inches), leaving a 1½-inch border at the ends. Arrange the caramelized onions in a single, 3-inch-wide strip on top of the mushroom mixture, leaving about ½ inch of the mushrooms exposed on both sides. Lay the portobello mushrooms on top of the onions in a single line, stem-side down. (If the portobellos are too large to all fit in a row, square off edges so the cut sides lay snugly without overlapping.) Spoon the remaining mushroom mixture on top of the filling, covering the portobello mushrooms, then gently pack the mushroom mixture to form an even layer on top. (You can shape this the same way you might shape a freeform meatloaf.)
• To assemble, lift one side of the puff pastry over the mushroom filling to almost completely cover it. Brush the surface of the puff pastry covering the mushrooms with the beaten egg. Lift the remaining puff pastry flap over the egg-washed puff pastry, gently stretching it if need be to create a second layer of puff pastry on top, then gently press the top layer of pastry onto the lower layer using your fingertips to seal. Brush the insides of the short ends of the puff pastry and press to seal. Trim any parchment paper that extends beyond the sheet pan.
• Brush the exposed puff pastry on top with the remaining beaten egg. Decorate the top of the puff pastry as you like: Create a cross-hatch pattern by gently slicing through only the top layer of puff pastry in parallel lines, then cutting parallel lines in another direction. (Apply very little pressure, as you only want to cut through the top layer of puff pastry, not the second layer.) You can also slice small decorative vents in the puff pastry (be sure to slice all the way through both layers of puff pastry), or top with additional strips or shapes made from egg-washed puff pastry.
• Transfer to the middle rack in the oven and bake until puff pastry is deep golden and flaky, 45 to 50 minutes. Let cool slightly on the baking sheet, about 10 minutes.
• While the Wellington bakes, prepare the optional port reduction: In a medium saucepan, heat the oil over medium. Add the shallot, garlic and peppercorns, and cook, stirring occasionally, until softened, about 3 minutes. Add the port, stock and thyme, and cook over medium-high until the sauce is thick enough to coat the back of a spoon, 25 to 30 minutes. Strain the sauce, discarding the solids. (You should have about 1/2 cup sauce.) Cover and set aside until ready to serve. When ready to serve, warm the sauce over medium. Once warmed, whisk in the butter, season to taste with salt and pepper and serve.
• To serve the mushroom Wellington, cut it crosswise into 8 even slabs. (Each slab will include a pretty cross-section showcasing the halved portobello mushroom in the center; this is considered the presentation side.) Serve each piece presentation-side up. Pass with port reduction for drizzling on top.

Steps:

• Heat the oven to 220C/200C fan/gas 7. Remove the stalks from the mushrooms. Heat half the oil in a large frying pan and sizzle the mushrooms for 3-4 mins on each side until golden and cooked through - add a drop more oil if needed. Lift the mushrooms out onto kitchen paper to drain.
• Place the same pan back on the heat with the rest of the oil. Fry the garlic for a moment, add the spinach to the pan, then cook for 2-3 mins over a high heat until completely wilted. Season with salt and pepper, then tip the spinach into a large sieve to drain thoroughly.
• On a lightly floured surface scattered with the thyme leaves, roll the pastry out to the thickness of a £1 coin. Using a saucer and a larger-size plate, cut out 4 circles about 5cm wider than the mushrooms (for the bottoms) and 4 circles about 10cm wider (for the tops), re-rolling the trimmings if you need to.
• Place the four smaller circles on a baking tray and top each with a quarter of the spinach, making sure the pile of spinach isn't wider than the mushrooms. Top the spinach with a slice of cheese, then a mushroom, smooth-side up, and top the mushroom with another slice of cheese. Brush the border to each circle with egg, then gently stretch the larger circle over the mushroom, trying not to trap any air, then press the edges together with a fork. Trim the edges with a knife if you want, then brush each generously with egg. Bake for 40 mins until golden, then leave to cool for a few mins before serving.
