Portobello Steaks With Mashed Celery Root Recipes

Steps:

• Remove stems and clean the mushrooms; set aside.
• Mix vinegar, Worcestershire, oil, garlic, onion powder, salt, and pepper together in a small bowl.
• Place mushrooms inside a large zip-top bag. Pour in the marinade and turn the bag so the mushrooms get evenly coated. Let sit in a refrigerator for a minimum of 5 minutes, or up to 12 hours.
• Spray a large skillet with cooking spray and heat over high heat. Grill mushrooms in the hot pan until heated through and browned, about 4 minutes per side.

Steps:

• Preheat the oven to 350˚F.
• Overnight, or several hours in advance, make the marinade and set it aside.
• Remove the stems from the mushrooms, then use a fork to remove the gills. Do so by gently scraping in the direction of the gills about 1/8-inch deep. Set the mushrooms top side down in a baking dish and pour the marinade over them. Let them sit for at least 20 minutes or up to 8 hours.
• While the mushrooms marinate, place the whole celery root into a glass baking dish with about 1/4 inch of water in the bottom. Cover the dish with tinfoil and roast the root in the oven for 45 minutes to 1 hour. Remove the tinfoil and allow the root to cool until you can handle it with your hands.
• Use a knife to peel away the celery root skin, then roughly chop the root and place the pieces into a food processor. Purée the root with the horseradish and coconut butter, and add enough almond milk for the mixture to reach a mashed potato-like texture and consistency. Season with sea salt then fold in the chopped scallions. Set aside and keep warm.
• Place the mushrooms onto a baking dish and cook in the oven until tender, about 10 to 12 minutes.
• Slice the mushrooms then set them on top of mounds of the celery root mash. Enjoy with garlicky greens or roasted asparagus.

Steps:

• Brush the mushrooms all over with olive oil. Sprinkle the pepper evenly over the gill sides (about 1/2 teaspoon per mushroom). Heat a large cast-iron skillet over medium-high, then add the mushrooms gill side up and sear until the underside is browned and the gill side looks wet, 3 to 6 minutes. Flip and cook until golden and the pepper is fragrant, 2 to 4 minutes.
• Reduce heat to medium-low. Flip the mushrooms so they're gill side up, then add the butter and garlic, and season with salt. While stirring the garlic to keep it from scorching, tilt the skillet to spoon up the melting butter and baste the mushrooms until tender, 2 to 5 minutes. Transfer the mushrooms to a plate, leaving the butter in the skillet.
• Add the shallot and stir until softened, 2 to 4 minutes, adding a little more butter if the pan is dry. Stand back, and carefully add the Cognac. (It might flame.) Stir until the Cognac has nearly evaporated. Add the heavy cream and mustard, season with salt, and stir to combine. Return the mushrooms to the pan gill side down, and cook until the cream is thickened and the color of a latte, 2 to 4 minutes. Eat the mushrooms with a drizzle of the sauce.
