Best Roasted Red Onion Mayo Recipes

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.

GRILLED APPLE, BACON AND CHEDDAR SANDWICH WITH ROASTED RED ONION MAYO

Steps:

• Preheat a seasoned grill pan or griddle over medium heat. Assemble this sandwich just as you would a traditional grilled cheese sandwich: spread 1 slice of bread with some Red Onion Mayo, then top with 2 slices Cheddar, the bacon, the apple slices, then 2 more slices of Cheddar, finishing with another mayo-slathered slice of bread. Butter the outsides of the bread and transfer to the hot grill. Grill about 3 minutes per side, since this sandwich is so thick. Remove to a cutting board and cut the sandwich in half on the diagonal to serve.
