Air Fryer Crispy Brussel Sprouts - Fast, Flavorful, and Perfectly Crunchy
Ingredients
- Brussels sprouts: About 1 to 1.5 pounds, trimmed and halved.
- Olive oil or avocado oil: 1.5 to 2 tablespoons, enough to lightly coat.
- Kosher salt: 1/2 to 3/4 teaspoon, to taste.
- Black pepper: 1/4 teaspoon, freshly ground.
- Garlic powder: 1/2 teaspoon for savory depth.
- Onion powder: 1/4 teaspoon (optional, but nice).
- Red pepper flakes: Pinch for a gentle kick (optional).
- Balsamic vinegar or lemon juice: 1 to 2 teaspoons for brightness at the end.
- Honey or maple syrup: 1 to 2 teaspoons for a light glaze (optional, balances bitterness).
- Parmesan cheese: 2 tablespoons, finely grated, for serving (optional).
- Equipment: Air fryer, large bowl, knife, cutting board, and tongs.
Instructions
- Prep the sprouts: Rinse Brussels sprouts. Trim the stem ends and remove any yellow or tough outer leaves. Slice sprouts in half lengthwise. For very large ones, quarter them for even cooking.
- Dry them well: Pat the sprouts dry with a clean towel. Removing moisture is key to crisp edges and less steaming in the air fryer.
- Season evenly: In a large bowl, toss sprouts with oil, salt, pepper, garlic powder, and onion powder. Add red pepper flakes if using. Make sure each piece has a light, glossy coat.
- Preheat the air fryer: Set to 375°F (190°C) for 3 to 5 minutes. A hot basket helps the cut sides caramelize quickly.
- Arrange in the basket: Spread the sprouts in a single layer, cut side down when possible. A few loose leaves are great—those get extra crispy. Cook in batches if needed to avoid overcrowding.
- Air fry until crisp-tender: Cook for 8 minutes, then shake the basket or flip with tongs. Continue for 4 to 6 more minutes, until edges are deeply browned and centers are tender when pierced. Total time is usually 12 to 14 minutes.
- Finish with acid and sweetness: Transfer to a bowl. Toss with balsamic or lemon juice and, if you like, a drizzle of honey or maple syrup. Taste and adjust salt and pepper.
- Serve hot: Sprinkle with Parmesan if desired and serve right away while the leaves are still crisp.
What Makes This Recipe So Good
- Super crispy texture: The air fryer circulates hot air so the leaves get shatter-crisp while the centers stay soft.
- Quick and low effort: Minimal prep, no long roasting time, and easy cleanup.
- Balanced flavor: A mix of salt, pepper, garlic, and a hint of sweetness brings out the sprouts’ natural nuttiness.
- Flexible and forgiving: Works with fresh or slightly older sprouts, and you can adjust seasoning to taste.
- Great for meal prep: Reheats well and stays tasty for days.
