How to Make Air Fryer Brussel Sprouts

If you don't have an air fryer, but you have an Instant Pot and the crisping lid, you're in luck! This recipe works perfectly with the Instant Pot's Crisping lid, which acts as a broiler and circulates hot air around your food – without bringing it to pressure. If you love the ease and convenience of an Instant Pot for meals that are only one pot to clean – you can love this recipe, too!

Steps To Air Fry Brussels Sprouts

Once you have assembled the ingredients, use this method:

Trim Brussels

Start by rinsing brussels sprouts well, trimming stems off, and cutting in half. Remove any discolored (lightly yellow) leaves from the outside of brussels sprouts.

Season Brussels

Add trimmed and halved brussels to a bowl and toss in olive oil, salt, pepper, and any desired spices and herbs.

Air Fry

We will air fry brussels sprouts for a few moments without cheese or breadcrumbs to soften and cook before finishing. Partway through cooking, flip brussels sprouts over. If adding breadcrumbs or keto breadcrumbs to brussels, add when adding cheese after flipping over brussels sprouts.

Fry to Crisp

Continue air frying until brussels sprouts are crisp and crunchy. Check as often as needed to ensure they don't burn.

Kitchen notes

Balsamic Brussels Sprouts. Drizzle balsamic glaze (we especially love fig balsamic glaze) over brussels sprouts when fresh out of the air fryer.

Make in Ninja Foodi. If you have a Ninja Foodi (our favorite pressure cooker/air fryer combo – the air fry and broil method on the Ninja tend to crisp better than the Instant Pot in our opinion – and it offers more space than the Phillips Air Fryer, though we do love both those tools as well, we like the Ninja the most for Air Frying without a larger standalone Air Fryer.) To make this dish in your Ninja Foodi set up as an air fryer, please remove pressure cooker lid and add air fryer lid, and place brussels in Foodi basket. select air fry cooking method.

Spicy Brussels Sprouts. To kick up the flavor of these brussels sprouts, you can a pinch of cayenne, paprika, aleppo pepper, guajillo pepper, fermented pepper, sweet chili sauce, or hot sauce when you add the salt and pepper.

Herbed Brussels Sprouts. Add Italian seasonings when adding the salt and pepper and use Italian seasoned bread crumbs or pork rinds (for gluten free.)
