An easy summery sauce made with roasted red peppers, basil, and mayo...use this on everything from burgers to grilled chicken to grilled veggies, or as a dip or spread.
This flavored mayo, kind of like a red pepper aioli, would be great on Chipotle Barbecue Turkey Burgers, Buffalo Turkey Burger Sliders, or even just a regular grilled hamburger. You can use homemade roasted red bell peppers or grilled red bell peppers (with the skins peeled off), or store-bought roasted red peppers. The taste is a little tangy, a little sweet, and this mayo packs a whole lot of summer flavor. And if you have some left after the burger party, it makes a really nice dip or sauce for other grilled foods, like grilled chicken breasts, grilled cod, or grilled halibut.
Served at room temperature, this red pepper mayo will be a looser type of sauce. If you want it to be thicker, use it cool from the fridge, and it will still get nice and runny when it hits a hot burger. If you use jarred bell peppers, make sure they are not pickled in vinegar, which will make the sauce overly tangy and a bit watery.

Ingredients
- Red bell pepper – When roasted, red peppers transform into such a sweet and silky treat.
- Garlic – For a bit of spiciness.
- Fresh basil – For sweet and aromatic notes.
- Mayonnaise – You can use any brand of mayonnaise you like. I like Hellman’s.
How to Make Roasted Red Pepper Basil Mayo
- Combine everything: In a food processor, pulse the pepper and garlic. Add in the basil and mayonnaise, then let the motor run until all is smooth and incorporated. Season with salt and pepper
Variations
- In addition to the basil, if you have some fresh thyme or oregano lying around, you could add in a teaspoon of that as well.
- If you wanted to use a different color bell pepper, that will make the sauce another pretty hue — don’t use green, though, as it’s not sweet enough. Yellow or orange or even purple will be great.
Storage
Red pepper mayo will last up to 2 weeks in a sealed container in the fridge.

Roasted Red Pepper Mayo
Ingredients
- 1 red bell pepper
- 1 teaspoon minced garlic
- 2 tablespoons chopped fresh basil
- ½ cup mayonnaise
- Kosher salt and freshly ground black pepper
Instructions
- Turn a gas grill to medium-high and place the pepper directly over the flame. Cook, turning it with tongs as the underside blisters and chars, until the whole pepper is blistered. Place in a bowl and cover with a dishtowel until cooked. Peel off the skin, discard any seeds, and rib from the inside of the pepper. Coarsely chop the pepper. (You can also roast the pepper underneath the broiler on a rimmed baking sheet.)
- Combine pepper and garlic in a food processor and pulse to combine. Pulse in the basil and mayonnaise, then let the motor run until all is smooth and incorporated. Season with salt and pepper.

A cute thing to do when you are hosting a grilling/burger gathering is to make up a few simple sauces and put them out for people to choose from. Yes, you should also probably put out ketchup, mustard, and relish, but here are some other sauces and spreads that would make any burger proud.
It will be helpful if the starting point for salt and pepper is included. A pinch, a dash? How much do you normally use? Thanks!
start with 1/2 teaspoon of kosher salt, and 1/4 teaspoon of freshly ground pepper, taste, and see what you think!!
