Roasted Onion Mayonnaise Recipes

Steps:

• Caramelized Onions:
• Heat the butter and oil in a medium saute pan over medium heat. Add the onions and cook, stirring occasionally, until golden brown and caramelized, season with salt and pepper.
• Roasted Tomato Mayonnaise:
• 1. Preheat the oven to 375 degrees F. Place the tomato in a small dish or baking sheet, drizzle with oil and season with salt and pepper. Roast until the tomato is very soft and golden brown, about 20 minutes. Remove from the oven and let cool slightly.
• 2. Put the mayonnaise, tomato, garlic and thyme in a food processor and process until smooth, season with salt and pepper. Scrape into a bowl.
• Sandwich:
• 1. Place 4 slices of the bread on a flat surface, divide half of the cheese among the slices. Top the cheese with 2 slices of prosciutto then top the proscuitto with some of the onions and the remaining cheese. Place the 4 remaining slices of bread on top to make four sandwiches. Butter the top of the bread using half of the butter.
• 2. Preheat a cast iron pan or cast iron griddle over medium heat. Place the sandwiches in the pan, butter-side down (may need to do in batches) and cook until lightly golden brown. Spread the remaining butter on the bread facing up, then flip and continue cooking until the bottom is golden brown and the cheese has melted. Serve with roasted tomato mayonnaise on the side.

Steps:

• Preheat oven to 375*F.
• Spread roughly chopped onions out on a small rimmed baking sheet and drizzle with olive oil. Sprinkle with salt and freshly ground black pepper. Toss all together to coat and spread evenly on the pan. Roast for 25-30 minutes, checking at 20 and again at 25. Onions should be soft and starting to brown. Remove from oven and let cool completely.
• Once onions are cooled, put them into a food processor and pulse until the onions are finely chopped. Add mayo and pulse until the spread becomes incorporated. Taste for desired seasoning, adding more if desired. (If the spread sits in the fridge overnight while flavors meld, the flavor will change, so use caution on the seasonings). I recommended that you make this at least 8 hours before using for best taste.
• Enjoy on anything that you like mayo spread on.

Steps:

• Adjust oven rack to lowest position; heat to 425 degrees.
• Cut onions in half; toss with oil and a generous sprinkle of salt and pepper. Place, cut-side down, on a lipped cookie sheet.
• Roast until tender and cut surfaces are golden brown, 25 to 30 minutes. Adjust seasonings; drizzle with balsamic vinegar.

Steps:

• Preheat the oven to 400 degrees F.
• Remove the stem end of each onion and carefully slice off the brown part of the root end, leaving the root intact. Peel the onion. Stand each onion root end up on a cutting board and cut the onion in wedges through the root. Place the wedges in a bowl.
• For the dressing, combine the lemon juice, mustard, garlic, thyme, salt, and pepper in a large bowl. Slowly whisk in the olive oil. Pour the dressing over the onions and toss well.
• With a slotted spoon, transfer the onions to a sheet pan, reserving the vinaigrette that remains in the bowl. Bake the onions for 30 to 45 minutes, until tender and browned. Toss the onions once during cooking. Remove from the oven, and drizzle with the reserved dressing. Sprinkle with parsley, season to taste and serve warm or at room temperature.

Steps:

• Preheat oven to 425°F. Line large rimmed baking sheet with foil. Gently toss red onions, 5 tablespoons oil and vinegar in large bowl. Sprinkle with salt and pepper. Arrange onions in single layer on prepared sheet. Bake onions until brown at edges and just tender, about 40 minutes. Cool.
• Mix mayonnaise, basil, lemon juice, lemon peel and 2 tablespoons oil in small bowl. (Onions and mayonnaise can be made 2 days ahead. Cover separately and chill.)
• Spread mayonnaise over cut sides of bread. Place bottom halves on plates. Top with roast beef, onions and arugula. Cover with top halves of bread.
