I’ll be honest — frozen veggies used to be my last resort, but once I started tossing them in the air fryer, everything changed. Brussels sprouts went from a soggy side dish to one of my weeknight MVPs. No chopping, no thawing, just straight into the basket and out come crispy, golden little bites that taste like they’ve been oven-roasted for an hour.
I love keeping a bag of frozen Brussels in the freezer for nights when I need something green fast. They pair perfectly with air fryer boneless skinless chicken thighs, healthy mac & cheese, and this secretly healthy alfredo pasta. Easy, healthy, and seriously addicting.

Why You’ll Love This Recipe

- Quick + easy – just 20 minutes in the air fryer.
- Crispy edges, tender inside – tastes like oven-roasted sprouts without the 45-minute wait.

Ingredients You’ll Need

- Frozen Brussels sprouts: I always keep a bag in my freezer for quick sides. No trimming or thawing needed — they go straight into the air fryer and crisp up beautifully.
- Olive oil or avocado oil: A light drizzle helps the spices stick and gives you that golden, roasted texture without needing a ton of oil. I like avocado oil for its high smoke point, but either works.
- Cornstarch: My secret ingredient for extra crunch! It soaks up any surface moisture and helps the edges crisp faster in the air fryer. Trust me.
- Garlic powder, salt, and black pepper: A simple but reliable combo that brings out the natural sweetness of Brussels sprouts. Garlic powder especially gives that savory, roasted flavor.
- Red pepper flakes (optional): For a touch of heat. I sprinkle these on when I’m making them just for me, but you can skip if serving to kids.

Substitutions & Variations
- Make it gluten-free: This recipe is naturally gluten-free.
- Make it dairy-free & vegan: Simply omit the parmesan cheese and use nutritional yeast instead for that cheesy flavor!
- Make it spicy: Sprinkle with cayenne or chili powder.
- Cornstarch substitute: If you don’t have it, arrowroot starch and tapioca flour work too.
- Fun flavor upgrades: Toss the cooked sprouts with balsamic glaze, buffalo sauce, honey mustard, homemade teriyaki sauce, or a drizzle of hot honey for a totally different vibe.
- Seasonings Swaps: Garlic powder is my go-to, but you can swap in onion powder, smoked paprika, or Italian seasoning for a different flavor twist.

Top Recipe Tips
- Cook from frozen, always: I’ve tested this recipe both ways, and sprouts actually turn out crispier if you skip thawing. Straight from the freezer is the way to go.
- Cornstarch is the secret weapon: After lots of testing, I’ve found a tiny dusting of cornstarch makes a big difference for crunch — especially if your sprouts come with ice crystals.
- Work in batches if needed: I’ve made these in both small and large air fryers. In smaller baskets, overcrowding leads to soggy sprouts. Spread them out and cook in two rounds if you need to.
What to Serve with Air Fryer Frozen Brussels Sprouts
These crispy Brussels sprouts make a super versatile side dish, so you can pair them with just about anything you’re cooking up for dinner.
- Protein mains: Try these grilled boneless skinless chicken thighs or this ground beef and zucchini casserole for a protein-packed meal, but they also go great with air fryer teriyaki salmon bites.
- Lighter options: Try them alongside my Blackened salmon Caesar salad or open-faced tuna melts.
- Comfort food: Serve them with this healthy mac and cheese or one pot lasagna soup.

Frequently Asked Questions
