How to Make Crispy Brussels Sprouts in the Air Fryer

Preheat the air fryer to 375°F (190°C). In a large mixing bowl, toss the halved Brussels sprouts with olive oil, salt, pepper, and garlic powder until evenly coated.
STEP TWO: Air fry the Brussels Sprouts
Place the Brussels sprouts in a single layer in the air fryer basket. Air fry for 12-15 minutes, shaking the basket halfway through for even cooking.
STEP THREE: Prepare the Parmesan topping
Once the Brussels sprouts are crispy, remove them from the air fryer and sprinkle with grated Parmesan cheese.
STEP FOUR: Make the Garlic Aioli
In a small bowl, combine mayonnaise, minced garlic, lemon juice, and a pinch of salt. Stir until smooth and well combined. Serve the crispy Brussels sprouts immediately with the garlic aioli on the side for dipping.

Recipe FAQs
Yes, you can cook frozen Brussels sprouts in the air fryer. Just make sure to thaw them first and pat them dry to remove excess moisture before air frying. They will not be as crispy as fresh brussel sprouts.
The best way to season Brussels sprouts for air frying is to toss them with olive oil, salt, pepper, and garlic powder. You can also add other seasonings like red pepper flakes, smoked paprika, or balsamic vinegar for extra flavor.
To prevent Brussels sprouts from getting soggy in the air fryer, make sure they are thoroughly dried after washing. Don't overcrowd the air fryer basket and shake the basket halfway through cooking to ensure even crisping.
