Best 5 Roasted Red Onion Mayo Recipes

ROASTED RED ONIONS

Steps:

• Halve 2 pounds unpeeled red onions; toss in a large bowl with 1/4 cup olive oil, 1 teaspoon sweet smoked paprika and a pinch each of sugar and salt. Place the onions cut-side down on a baking sheet; roast at 450 degrees until soft and browned, 30 minutes.

SOUR CREAM AND ROASTED RED ONION DIP

Steps:

• Heat the oven to 400 degrees, and line a baking sheet with parchment paper. Arrange the onion slices in a single layer on the prepared sheet, leaving room between each. (Use 2 baking sheets if the onions won't all fit comfortably on 1.) Drizzle with olive oil, sprinkle with 1 teaspoon salt and the sugar and gently flip to coat, keeping the rings as intact as possible. Cook for 30 to 40 minutes, turning once, until soft and browning (It's O.K. if some parts get crisp and charred).
• Let the onions cool slightly, then transfer to a cutting board and roughly chop. (You want to have small pieces of onion without making a paste.)
• Transfer the onions to a medium bowl and add the sour cream, yogurt, mayonnaise, garlic, remaining 3/4 teaspoon salt, lemon juice and black pepper. Fold to combine.
• Transfer to a serving dish and garnish with minced chives. Serve with potato chips.

ROASTED RED ONION MAYO

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.
