The combination of Brussels sprouts, bacon, onion, and garlic creates a savory and aromatic dish with a variety of flavors.

The air frying method helps achieve crispy Brussels sprouts while perfectly cooking diced red onion and infusing the bacon flavor. It’s a tasty and satisfying way to enjoy a flavorful vegetable dish.

Brussels sprouts are surprisingly nutritious but can have a bitter flavor if eaten plain. Something that helps counter that in this tasty dish is the addition of soy sauce.

In this air fryer recipe, the saltiness of the soy sauce helps balance the flavor, and to add a little extra pop of flavor, I combined it with diced bacon and red onion. The red onion is caramelized, and the crispy bacon gives a salty and tasty crunch. It’s the best way to serve Brussels sprouts!
