The trick I’ve found (and that this recipe uses) is to soak the Brussels sprouts in water before seasoning and tossing them into the fryer. During soaking, water gets trapped between the leaves, which will turn to steam in the heat of the air fryer. This ensures that they don’t have an unpleasant, raw bite.  I love air fryer Brussels sprouts as a side at dinner, but I’ve also been known to snack on them throughout the day. Even though they need about 15 minutes to soak, this recipe come together in less time than cooking them in the oven and they are easy enough to make at a moment’s notice.

Tips for the Best Air Fryer Brussels Sprouts 

Just like ovens or stovetops, all air fryers work slightly differently from one another. Soaking the Brussels sprouts helps to ensure the sprouts are cooked through, but also slows down the speed at which the sprouts brown, reducing the risk of burning. Still, because all air fryers are different and some can run hotter, it doesn’t hurt to keep an eye on the sprouts during cooking.

Easy Variations

I season Brussels sprouts simply with olive oil, salt, black pepper, and crushed red pepper, but you can easily dress them up with nutty Parmesan or bright lemon zest.

Lemon: Finely zest about half a lemon over the sprouts before serving.  Balsamic: Drizzle them with balsamic glaze after air frying.   Parmesan: In the last few minutes of cooking, grate Parmesan cheese over the Brussels sprouts in the air fryer. Continue cooking for the last few minutes until the sprouts are crisp and tender and the cheese is toasty and starting to brown. Top with more grated Parmesan if desired. Breadcrumbs: Top the cooked sprouts with toasted, garlicky breadcrumbs. 

How to Reheat Air Fryer Brussels Sprouts

Preheat the air fryer to 375°F (if needed) on the air fryer setting (if your model has multiple settings).Place the leftover Brussels sprouts in the basket of the air fryer in a single layer. Return the basket to the fryer and reheat until the sprouts are heated through and have re-crisped on the outside, about 3 minutes. Serve immediately.

Transfer the cut Brussels sprouts to a medium bowl and cover with hot water. The water doesn’t need to be boiling; the hottest temperature water that comes out of your tap is okay.  Let the Brussels sprouts soak for about 15 minutes. Soaking the Brussels sprouts lessens some of the bitterness as well as traps moisture between the leaves, which turns to steam during frying and ensures the sprouts are tender and cooked through. Transfer the soaked Brussels sprouts to a strainer and shake over the sink to get rid of the excess moisture from the outside of the sprouts. Rinse and dry the medium bowl used to soak the Brussels sprouts and place the cut sprouts back into the bowl. Transfer the Brussels sprouts to a plate and serve immediately while still crisp.  Store any leftovers in an airtight container in the refrigerator for up to 3 days.  Did you love the recipe?
