Extra-Crispy Air Fryer Brussels Sprouts
These air fryer Brussels sprouts come out deeply browned and crackly on the outside in about 15 minutes. No soggy centers, no waiting for the oven, just a side dish that makes people grab seconds.
If you have ever been burned by limp, steamed sprouts, the air fryer changes everything. You get those dark, crispy leaves you usually only see in restaurant versions, with almost no effort.
What Makes These Air Fryer Brussels Sprouts So Good
The high, dry heat of the air fryer forces moisture off the surface fast, so the leaves crisp instead of steaming. That means you get the nutty, almost sweet flavor that only happens when Brussels sprouts char a little.
A simple mix of olive oil, salt, and pepper is all you need. The sprouts carry the rest of the flavor on their own, no heavy sauces required.
I make these when the rest of the meal is simple, maybe a roast chicken or a steak, because the sprouts taste like they took real work. They never fail to turn out crispy, even on the first try.
Ingredients
- 1 lb Brussels sprouts: look for tight, bright green heads without yellowing leaves
- 2 tbsp olive oil: extra virgin works, but any neutral oil is fine
- 3/4 tsp kosher salt: Diamond Crystal if you have it; use a little less if using table salt
- 1/2 tsp black pepper: freshly cracked gives a better bite
- 1/2 tsp garlic powder: optional, but adds a savory depth
- Balsamic glaze or grated Parmesan: for finishing, pick one or both
Variations / Substitutions
- No oil: toss the sprouts with 2 tbsp vegetable broth and a pinch of salt before air frying; they will not get quite as crispy but still work
- Spicy: add 1/4 tsp red pepper flakes or a pinch of cayenne with the seasonings
- Maple: drizzle 1 tbsp maple syrup over the sprouts during the last 2 minutes of cooking for a sweet, sticky glaze
- Cheesy: toss hot sprouts with 2 tbsp grated Parmesan and a squeeze of lemon right after cooking

How to Make Extra-Crispy Air Fryer Brussels Sprouts
Step 1: Trim and Halve the Sprouts
Start by trimming the dry stem end off each Brussels sprout, just enough to remove the tough bit. Then cut them in half lengthwise, keeping the core intact so the leaves hold together.
You want all the halves close to the same size. That way they cook evenly, and the little loose leaves that fall off while you trim turn into crunchy chips in the air fryer basket.
Step 2: Toss with Oil and Seasonings
Place the trimmed sprouts in a large bowl. Drizzle the 2 tbsp olive oil over the top and sprinkle on the 3/4 tsp salt, 1/2 tsp pepper, and the garlic powder if you are using it. Toss well with your hands or a spoon until every sprout feels lightly coated and the seasoning is distributed.
The oil should just glisten on the leaves, not pool in the bottom of the bowl. If some halves look dry, give them one more quick toss.
Step 3: Air Fry Until Deeply Browned
Preheat your air fryer to 375°F (190°C) for 3 minutes. Arrange the seasoned sprouts in a single layer in the basket, cut side down for maximum browning. Cook for 8 minutes, then shake the basket or flip the sprouts. Continue cooking for another 6 to 8 minutes, until the edges are dark brown and the leaves look crispy and shaggy.
Right around the 14-minute mark, the smell will shift from earthy to nutty and toasty. That is your cue they are almost ready. If you like them extra charred, let them go another minute.
Step 4: Drizzle and Serve Hot
Transfer the sprouts to a serving plate while they are still piping hot. Drizzle lightly with balsamic glaze or shower them with grated Parmesan, whatever you are in the mood for. A small finishing pinch of salt right before serving wakes everything up.
Serve them right away while the edges are still crackly. They soften as they sit, so this is one dish best eaten fresh.
Tips for the Crispiest Sprouts
- Dry the sprouts thoroughly after washing. Any leftover water will steam the sprouts and soften the crisp edges.
- Do not crowd the basket. The sprouts need space around them for air to circulate, or they will steam in their own moisture.
- Toss the loose, single leaves that fall off during trimming into the basket too. They turn into crunchy little chips faster than the halves.
- If you want more char, increase the temperature to 400°F (200°C) for the last 2 minutes, but watch them closely so they do not burn.
Air fryers vary, so use these times as a starting point:
| Air Fryer Style | Cook Time |
|---|---|
| Basket-style, single layer | 14 to 16 mins |
| Oven-style with trays | 16 to 18 mins |
Keeping Leftover Sprouts Fresh
- Refrigerate: store cooled sprouts in an airtight container for up to 3 days.
- Reheating: the air fryer brings them back best. Reheat at 350°F for 3 to 4 minutes to re-crisp the edges. A skillet over medium heat also works.
What Goes Well With These Sprouts
They pair naturally with roasted chicken, where the crispy skin and the crackly sprout edges play off each other. A pan-seared steak works just as well, especially if you finish the sprouts with a little balsamic glaze that echoes the meat’s char. For a seafood option, try them alongside a simple broiled salmon fillet, the richness of the fish balances the earthy sprouts.
Frequently Asked Questions
Can I use frozen Brussels sprouts?
Yes, but they will be less crispy. Thaw them completely, pat them very dry, and expect to add 3 to 4 extra minutes of cook time. The texture will be softer inside.
Do I need to preheat the air fryer?
Yes, a short preheat helps the sprouts start crisping as soon as they hit the basket. Without it, the first few minutes are spent warming up, and you lose some of the browning.
What dipping sauce goes well with these sprouts?
A quick lemon-garlic aioli works great, or even plain Greek yogurt with a splash of lemon juice and black pepper. The creamy dip cools the charred leaves.
Can I double the recipe?
You can, but you will need to cook in batches. Overfilling the basket wrecks the crispiness because the sprouts will steam instead of fry. Two batches is far better than one soggy batch.
