How to Cook Brussels Sprouts in Air Fryer (Quick and Easy)

Brussels sprouts used to make people groan. But honestly, the air fryer changed everything. So many people boil them and end up with something sad and soggy. This article shows you exactly how to cook Brussels sprouts in air fryer the right way, with the perfect time, temp, and tips for crispy results every single time.

Key Takeaways: Wash and dry your Brussels sprouts completely, then trim the ends and cut them in half. Toss with olive oil, salt, and pepper. Set your air fryer to 375°F and cook halved Brussels sprouts for 12 to 15 minutes, shaking the basket halfway through. They should look golden and crispy on the outside but soft inside.

How Long to Cook Brussels Sprouts in Air Fryer?

This is the most common question, and for good reason. Get the time wrong and you either eat raw sprouts or burnt ones. Neither is fun. So let’s make it simple.

For halved Brussels sprouts, 12 to 15 minutes at 375°F is the sweet spot. Whole sprouts take a bit longer, around 18 to 20 minutes. Smaller ones cook faster, so always check around the 10-minute mark just to be safe.

Every air fryer runs a little differently too. Some run hotter, some don’t. So the first time you make these, peek at them around minute 10 and adjust from there. That one habit will save your sprouts every time.

Also, don’t skip shaking the basket halfway through. That step makes sure every side gets crispy and nothing burns on the bottom. It takes two seconds and makes a big difference.

• Halved Brussels sprouts: 12 to 15 minutes at 375°F
• Whole Brussels sprouts: 18 to 20 minutes at 375°F
• Shake the basket at the halfway point every time
• Smaller sprouts cook faster, so check them early
• Overcrowding the basket slows down cooking and ruins crispiness
• Always dry them well before cooking or they steam instead of crisp

How to Cook Brussels Sprouts in Air Fryer the Right Way

This is your full step-by-step guide. Follow this and you’ll get golden, crispy, delicious Brussels sprouts every single time.

Step 1: Pick and Prep Your Brussels Sprouts

Start with fresh Brussels sprouts if you can. Frozen ones work too, but fresh ones get crispier and taste better overall. Look for firm, bright green ones with tight leaves.

Once you’ve got them, rinse them well under cold water. Then, and this part really matters, dry them completely. Pat them dry with a paper towel or let them air dry. Any water left on them turns into steam in the air fryer, and steam makes them soft instead of crispy.

After drying, trim off the tough bottom end and pull away any yellow or loose outer leaves. Those burnt leaves aren’t fun to eat.

• Buy fresh, firm, bright green sprouts
• Rinse under cold water thoroughly
• Pat completely dry with a paper towel
• Trim the bottom stem off each one
• Remove any yellow or wilted outer leaves
• Smaller sprouts cook more evenly, so size matters

Step 2: Cut Them in Half for Better Results

Cutting your Brussels sprouts in half is not just a suggestion. It’s the move. The flat cut side goes face down in the air fryer, and that’s where you get that gorgeous golden crust.

Halved sprouts also cook faster and more evenly than whole ones. So you get better texture in less time. That’s a win on both sides.

If your sprouts are really tiny, you can leave them whole. But for most regular-sized ones, cut straight through the middle from top to bottom.

• Cut each sprout straight down the middle
• Place flat side down in the air fryer basket
• Flat side = the crispy, golden side you want
• Tiny sprouts can stay whole if needed
• Even halves cook more evenly than uneven cuts
• Don’t quarter them, they get too small and burn easily

Step 3: Season Them Right

Here’s where the flavor comes in. Keep it simple or go bold, either works. But you always need olive oil, salt, and pepper as your base. Without oil, they dry out instead of crisping up.

Toss your halved sprouts in a bowl with about 1 to 2 tablespoons of olive oil. Add salt, pepper, and garlic powder if you like. Some people add a little balsamic vinegar or parmesan at the end too, and honestly that combo is incredible.

Make sure every sprout is coated in oil. Dry spots won’t crisp up. So take an extra minute to toss them well before they go in the basket.

• Use 1 to 2 tablespoons of olive oil per pound
• Always add salt and black pepper
• Garlic powder adds a nice savory kick
• Toss well so every piece gets coated
• Add parmesan or balsamic after cooking, not before
• Avoid too much oil or they get greasy instead of crispy

Step 4: Set Your Air Fryer the Right Way

Preheat your air fryer for about 3 minutes before you add the sprouts. A hot basket helps them start crisping right away instead of slowly warming up. This small step actually makes a real difference.

Set the temperature to 375°F. That’s the sweet spot for Brussels sprouts. Too low and they go soft. Too high and the outside burns before the inside cooks through.

Place your sprouts in a single layer with the flat side down. Don’t pile them on top of each other. Crowding the basket traps steam and kills the crispiness completely.

• Preheat for 3 minutes before adding sprouts
• Set temperature to 375°F
• Always use a single layer in the basket
• Flat side faces down for the best crust
• Cook in batches if you have a lot of sprouts
• Never stack them, even a little

Step 5: Cook and Shake at the Right Time

Put the basket in and set your timer for 12 to 15 minutes. But at the 7-minute mark, pull out the basket and give it a good shake. This flips the sprouts around and lets all sides get some heat.

After shaking, slide the basket back in for the rest of the time. In the last couple of minutes, peek through the window or open it quick to check the color. You want them golden brown, not dark brown.

Pull them out the second they look right. Leaving them in even 2 extra minutes can turn perfect sprouts into bitter, overdone ones. So stay close during that last stretch.

• Set timer for 12 to 15 minutes total
• Shake the basket hard at the 7-minute mark
• Check color in the last 2 minutes
• Golden brown is perfect, dark brown is too far
• Pull them out right when they look done
• Let them sit for 1 minute before serving

Step 6: Serve Them While They Are Hot

Brussels sprouts are best eaten right away. As soon as they sit too long, that crispiness starts to fade. So time them to come out of the air fryer close to when you’re ready to eat.

Right out of the basket, you can finish them with a squeeze of lemon, a sprinkle of parmesan, or a drizzle of balsamic glaze. These little additions make them feel fancy without any extra effort.

If you have leftovers, store them in an airtight container in the fridge. Then, reheat them in the air fryer at 350°F for about 4 minutes to bring back some of that crunch.

• Serve immediately after cooking
• Finish with lemon juice, parmesan, or balsamic glaze
• Don’t let them sit out too long or they soften
• Store leftovers in an airtight container
• Reheat in the air fryer, not the microwave
• Microwaving makes them soggy all over again

How Long to Cook Halved Brussels Sprouts in Air Fryer?

Halved Brussels sprouts are honestly the best way to do it. And the time question is super important here because it’s the difference between perfect and awful.

At 375°F, halved Brussels sprouts need about 12 to 15 minutes. The flat side gets beautifully caramelized and golden. The inside stays soft and tender. That contrast is exactly what makes them so good.

Halfway through cooking, shake the basket. That one move helps the rounded sides get some color too, not just the flat cut side. So you end up with crispy edges all around.

If your sprouts are on the larger side, go closer to 15 minutes. Smaller ones are usually done around 12. The best way to know is just to look at them. Golden and slightly charred on the edges means they are ready.

• Halved sprouts cook in 12 to 15 minutes at 375°F
• Flat side down gives the best caramelized crust
• Shake the basket at the halfway point
• Larger halves need closer to 15 minutes
• Small halves are usually ready around 12 minutes
• Look for golden edges, that’s your sign they’re done

How to Make Brussels Sprouts Crispy and Not Soggy?

Soggy Brussels sprouts are a real disappointment. But the good news is, it almost always comes down to a few fixable mistakes.

The biggest one is moisture. If your sprouts are wet when they go into the air fryer, they steam instead of roast. So dry them completely before adding oil and seasoning. That step alone fixes so much.

The second issue is overcrowding. When you pile too many into the basket, hot air can’t move around each sprout. So instead of crisping, they just sit there and steam each other. Cook in batches if you have a lot.

The third thing is oil. You need some. Not a ton, but enough to coat each piece. Oil helps the outside brown and crisp. Without it, you just get dry and chewy sprouts that nobody wants.

• Dry sprouts completely before seasoning them
• Never cook in a crowded basket
• Always use some olive oil, it helps them crisp
• Don’t use too much oil either, a light coat is enough
• Cook at 375°F, not lower
• Shake the basket halfway through every single time
