Appetizers Sides

Roasted Brussels Sprouts with Roasted Garlic Aioli

Take simple roasted brussels sprouts up a notch by pairing them with a creamy garlic and lemon aioli.

I love a good charred brussel sprout. We make these in the oven, super simply, with olive oil, salt and pepper. Adding an aioli on the side takes them up a notch and makes a nice presentation to turn a side dish into an party-ready appetizer.

Aioli is traditionally a Mediterranean sauce made with garlic and olive oil, similar in taste and consistency to a mayonnaise. The bright lemon flavors in this creamy garlic aioli are a perfect complement to the flavor of the oven roasted brussels sprouts.

If you are a brussels sprouts fan — you’ll enjoy the pairing of the aioli!
