“Caramelized onions accent the mayonnaise in this delicious sandwich spread.” - by mistycolleen
Original recipe yields 3 cups
- Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with aluminum foil and lightly grease.

- Place the onions into a food processor or blender, add the mayonnaise, and puree until smooth. Season to taste with salt and pepper. Store in the refrigerator.

"I halved this recipe. I did drizzle a little EVOO over the onions before baking and the mayonnaise I used was reduced fat. I made no other changes. I actually made this the night before last as I want..." See moreed it to sit in the fridge for as long as possible before using. This. Is. MONEY. I used this in a BLT Sandwich Wrap for dinner last night and let me tell you, it made the wrap incredible. I don't know why I haven't heard of this before but you bet that I'll make this frequently. This would be a wonderful addition to homemade ranch dressing or Secret Sauce. What a killer idea!"
"THIS ROCKS!!!! If I could give it 10 stars, I would. The roasting of the onions brings out the flavor. This was delicious on hamburgers, but our favorite thing is to use it as a french fry dipping ..." See moresauce. Everyone I have served this to, loves it. Great stuff. Thank you!"
"This was awesome. I am having burgers tomorrow so I wanted something with alittle zing and this is it. I used about 3/4 cup of mayo and 1 medium onion. Cut the onion into fourths and added 2 cloves..." See more of garlic...drizzled with EVOO and salt and pepper, cooked for about 35 minutes and let my blender do the rest....AWESOME"
