Air Fryer Brussels Sprouts Recipe

If you want crisp, caramelized Brussels sprouts without fuss, the air fryer is the way. I roast these often—they’re easy, don’t heat up the kitchen, and usually get kids and adults to eat more greens. Here’s how I do it.

What You’ll Need

• Brussels sprouts, about 1 pound. Look for bright green, firm ones. Wilted ends are okay—just trim them off.
• Olive oil, around 1 tablespoon. It keeps things crispy, not mushy.
• Salt, to taste. Kosher salt is what I use.
• Black pepper, a few grinds. Fresh is best, but ground works fine.
• (Optional) Parmesan cheese, grated. About 1/4 cup if you want a cheesy finish.
• (Optional) Garlic powder, 1/2 teaspoon. Adds a little bite.
• (Optional) Red pepper flakes, a pinch. For heat if you like.

How to Prep

Start by rinsing the Brussels sprouts. Cut off any brown ends. Remove loose outer leaves—they crisp up nice. Cut each sprout in half from top to bottom. Big sprouts can be quartered. Try to keep pieces the same size so they cook evenly.

Put the sprouts in a bowl. Drizzle olive oil and toss with your hands until lightly coated. If you’re using garlic powder, pepper flakes, or other seasonings, add them now. Add salt and pepper last—start easy and add more later if you need.

Cooking in the Air Fryer

Set your air fryer to 360°F (180°C). Spread the sprouts in the basket. Don’t crowd—air should flow around them. If you have a lot, cook in batches.

Cook for about 10 minutes. Shake the basket about halfway. This stops sticking and helps them brown evenly. Check at 8 minutes—some air fryers run hot.

They should look brown and crispy outside, tender inside. If not, give them another minute or two. You know Brussels sprouts are done when a fork slides in easily.

Finishing Touches

If you’re adding Parmesan, sprinkle it on now and air fry 1 more minute so the cheese melts in.

Serving Ideas

Eat them right away when they’re hottest and crispiest. I serve these as a quick side with roasted chicken or pork chops. Or toss them with pasta or drop a handful on a salad. Sometimes I mix in toasted walnuts or almonds. And I love a squeeze of lemon juice for brightness.

What If They’re Not Crispy?

If your sprouts come out a little soft, next time try a bit more oil or shake the basket more often. If the edges are too dark, lower the temp by 10°F. Every air fryer is a little different—you’ll get a feel for yours.

Leftovers

Leftover Brussels sprouts aren’t as crisp, but they’re still good. I reheat them in the air fryer for 2-3 minutes, or use them on top of a grain bowl the next day.

Variations

• Add a dash of honey or maple syrup after cooking for a sweet-spicy mix.
• Mix in halved cherry tomatoes or thin slices of red onion before air frying.
• For a balsamic touch, drizzle a little right after cooking.
• Smoked paprika or cumin gives them a smoky flavor.

Common Questions

Why do I need to halve the sprouts?
Cutting them helps the insides cook and the outside crisp. Whole sprouts can stay chewy in the middle.

Should I preheat the air fryer?
I skip it. These cook fast either way. But if yours takes a while to heat up, you might try preheating for 2-3 minutes.

Can I use frozen Brussels sprouts?
You can, but they’ll release more water and won’t crisp as well. If you must use frozen, pat dry a bit and add a few extra minutes.

How do I make sure they’re not bitter?
Crispiness helps, but a little lemon or vinegar right at the end also balances bitterness.

What about the smell?
Cooking Brussels sprouts can have a strong smell. The air fryer keeps it mostly contained, but open a window if it bothers you.

Why I Like This Method

It’s easy to do a few servings for a side dish or a big batch for meal prep. The air fryer doesn’t smoke up the kitchen like roasting sometimes does. And Brussels sprouts are cheap in season, so this is a good way to use them.

What I Wish I Knew When I Started

Sometimes I’d spray oil instead of drizzling, but olive oil in a bowl works just as well and doesn’t clog up my air fryer. I’d also forget to shake the basket, so some pieces would get too dark. Now I set a timer for 5 minutes to remind myself.

Final Tweaks

Taste before you serve. Sometimes another pinch of salt or a grind of pepper makes all the difference. And if my kids are around, I sprinkle on extra cheese or drizzle a little honey. It’s not fussy—just do what you like.
