Roasted Red Onion Mayo

by Laura

I love the flavor of onion. It goes well with so many things. I especially love it on burgers and sandwiches, but I don’t like it when it’s raw. This is where this roasted red onion mayo comes in.

This recipe is the perfect way to get that onion flavor on you burgers and sandwiches with out having to have it raw. Plus, it is super simple to make!

All you need is 3 ingredients plus some salt and pepper (I always count these as free ingredients and never include them in my ingredient count). You obviously need a red onion. It gets finely diced and tossed with olive oil, salt, and pepper. It then get’s roasted in the oven. This really helps develop an awesome flavor from the onion and brings out the sweetness from the red onion.

Now really, you could do a bunch of roasted onion and keep measure amounts of it in the freezer for whenever you want to make this mayo. You can also keep some onion in a container in the fridge for a month and add it to mayo as needed. The actual mayo itself will keep for up to 2 weeks in the fridge.

This is my new favorite condiment. It adds such a great flavor to whatever I add it to. Be sure to check back tomorrow. I have a great sandwich recipe to use this mayo on.
