This air fryer Brussels sprouts recipe is made with bacon, diced red onion, soy sauce, and garlic to give a tasty blend. It’s a quick and easy side to pair with dinner tonight!

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!
Keto
This air fryer Brussels sprouts keto recipe is delicious with a hint of bacon and diced red onion. It falls in line with the keto diet by being low carb and having some protein and fat needed from the bacon.

Storing Brussels Sprouts
Store leftovers in an airtight container for up to 3 to 5 days.
If you want to extend their shelf life further, you can also freeze cooked Brussels sprouts. Freezing them can allow them to last for several months. To freeze cooked Brussels sprouts, place them in airtight freezer bags or containers, making sure to remove as much air as possible before sealing. Properly frozen Brussels sprouts can maintain their quality for up to 10 to 12 months in the freezer.
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 to achieve crispy Brussels sprouts while cooking the other ingredients to perfection. It’s a tasty and satisfying way to enjoy a flavorful vegetable dish.
