Air Fryer Frozen Brussels Sprouts (Crispy, No Thawing)

Air fryer frozen Brussels sprouts go straight from the bag to the basket. You get browned, crisp-edged sprouts with tender centers in about 18 minutes, with no thawing, trimming or cutting.

The trick is cooking them in two stages. First they cook plain to drive off the ice. Then you toss them with oil and seasoning and finish them hot. Seasoning frozen sprouts at the start mostly washes off as they thaw, and the oil can’t crisp anything while the outside is still wet.

I keep a bag of frozen Brussel sprouts in the freezer for busy weeknights and for holiday dinners when the oven is full. If you’re starting with fresh sprouts, my Air Fryer Lemon Pepper Brussels Sprouts are made for those.

The first time I made frozen Brussels sprouts in the air fryer, I was surprised by how nicely the edges browned without thawing them first. I used my Cuisinart Air Fryer with a 6-quart basket, cooking in small batches so the sprouts had room to crisp up.

Can You Cook Frozen Brussels Sprouts in the Air Fryer?

Yes, and you should cook them straight from frozen. Thawed sprouts release water and turn soft and mushy before they ever brown. Frozen sprouts hold their shape, so the outer leaves crisp while the inside steams tender.

One honest note: frozen sprouts won’t get quite as crunchy as fresh ones. They’re blanched before freezing, so they start out softer. What you get is deep browning on the outside leaves and a sweet, creamy center.

​Ingredients

The full amounts are in the printable recipe card below.

• Frozen Brussels sprouts (16 oz bag): Bags labeled “petite” or “baby” cook more evenly. Large frozen sprouts can stay firm in the middle.
• Olive oil or avocado oil (1 tablespoon): Added after the first stage, so it coats dry sprouts instead of sliding off icy ones.
• Kosher salt and black pepper: Season after the first stage for the same reason.
• Garlic powder (optional): A little goes a long way.
• Finishing touches (optional): Grated Parmesan, a squeeze of lemon, or a drizzle of balsamic.

How to Cook Frozen Brussels Sprouts in the Air Fryer

Step 1: Preheat. Heat the air fryer to 400°F for 3 minutes.

Step 2: Cook them plain. Spread the frozen sprouts in a single layer in the basket. Air fry for 8 minutes. They’ll look thawed, a little wet, and only lightly browned.

Step 3: Season. Tip the sprouts into a bowl. Toss with the oil, salt, pepper and garlic powder. Want them halved? Now is the time. They’re soft enough to cut easily, and every cut side browns.

Step 4: Finish. Return the sprouts to the basket in a single layer. Air fry 6 to 10 minutes more, shaking once, until the outer leaves are deep golden and the centers are fork-tender.

Step 5: Serve right away. Add Parmesan, lemon or balsamic if you like.

Time and Temperature Guide

All times are at 400°F, starting from frozen. Treat them as starting points, since air fryers vary by model and wattage.

Amount	Basket size	Stage 1 (plain)	Stage 2 (oiled)	Total
10–12 oz bag	4 qt or larger	7 min	6–8 min	13–15 min
16 oz bag	5–6 qt	8 min	6–10 min	14–18 min
16 oz bag	4 qt	Cook in 2 batches	6–8 min per batch	About 30 min
32 oz (2 bags)	Dual-basket	8 min	8–10 min	16–18 min

For a holiday crowd, a dual-basket air fryer lets you cook two bags at once. Otherwise, cook in batches and rewarm the first batch for 2 minutes before serving.

Tips for Crispy, Not Soggy, Sprouts

• Salt at the end too. A pinch of flaky salt right before serving tastes brighter than salt baked on.
• Don’t thaw them. Thawing is the main cause of mushy sprouts.
• Use one layer. Piled sprouts steam each other. If they overlap, cook in batches.
• Oil after stage one. Oil on icy sprouts pools in the bottom of the basket instead of coating them.
• Don’t skip the shake. The sides touching the basket brown first, so turn them once during stage two.
• Pat off extra frost. If the bag has a lot of ice crystals, knock them off before cooking.

Flavor Variations

Add these during stage two, when the sprouts are dry enough to hold onto a coating.

• Parmesan garlic: Add garlic powder with the oil. Sprinkle grated Parmesan over the sprouts for the last 2 minutes so it melts without burning.
• Honey balsamic: Toss the finished sprouts with balsamic and a little honey. My Crispy Air Fryer Honey Balsamic Brussels Sprouts has the full glaze.
• Bacon: Stir in chopped cooked bacon at the end. For the full version, see my Air Fryer Brussels Sprouts and Bacon. For a sweet-salty twist, use crumbled Bob Evans-style candied bacon.
• Caramelized, restaurant-style: My Seasons 52 Caramelized Brussels Sprouts copycat shows how to get that sticky, sweet glaze.
• Lemon pepper: Swap the black pepper for lemon pepper seasoning and finish with fresh lemon juice.
• Spicy: Add a pinch of red pepper flakes with the oil, or toss with hot sauce and melted butter at the end.

What to Serve With Air Fryer Brussels Sprouts

These go with almost any main. A few pairings that make a complete air fryer dinner:

Holiday table: They free up oven space next to the turkey or ham, and they’re ready in the time it takes to carve.

Salmon: Frozen Salmon in the Air Fryer also cooks straight from frozen, so the whole dinner comes out of the freezer.

Steak: Serve them next to Air Fryer New York Strip Steak with Boursin for a steakhouse-style plate.

Pierogies: Easy Air Fryer Pierogies and Onions plus these sprouts makes a fast meatless dinner.

Eggplant Parmesan: Pair them with Crispy Air Fryer Eggplant Parmesan for a vegetarian main.

Storing and Reheating

• Fridge: Cool completely, then store in an airtight container for up to 3 days.
• Reheat: Air fry at 350°F for 3 to 4 minutes, shaking once. The microwave works but softens them.
• Freezing leftovers: Not recommended. Sprouts that were frozen, cooked and frozen again turn mushy.

FAQs

Do I need to thaw frozen Brussels sprouts before air frying? No. Cook them straight from frozen. Thawed sprouts get soggy before they brown.

Why are my frozen Brussels sprouts soggy? Usually one of three things: they were thawed, the basket was overcrowded, or they were oiled while still icy. Cook in one layer and add the oil after the first 8 minutes.

Can I cut frozen Brussels sprouts in half? Not while they’re frozen solid. Cut them after the first stage, when they’ve softened. Halving them then gives you more browned, crispy edges.

What temperature do I air fry frozen Brussel sprouts at? 400°F. Lower temperatures thaw them slowly and they steam instead of browning.

How long do frozen Brussels sprouts take in the air fryer? About 14 to 18 minutes for a 16 oz bag: 8 minutes plain, then 6 to 10 minutes after tossing with oil.

Do I need oil? No, but a tablespoon makes a big difference in browning and flavor. Cooking spray works too.

Can I cook Trader Joe’s or store-brand frozen sprouts this way? Yes. Any plain frozen Brussels sprouts work. Skip bags that come with a sauce packet, or add the sauce only at the end.

Can I make them in the oven instead? Yes. Roast at 425°F on a sheet pan for 15 minutes, toss with oil and seasoning, then roast 10 to 15 minutes more.
