The 1500W PowerPod and borosilicate glass container do the heavy lifting, turning a plain bag of sprouts into the best air fryer Brussels sprouts you’ve made at home.

Below you’ll get the exact settings, timing, and the one toss-halfway trick that guarantees golden, crackly sprouts every single time.

Why You’ll Love These Ninja Crispi Brussels Sprouts

• Genuinely crispy, never steamed. The Ninja Crispi pushes superheated air up to 450°F, blasting moisture off the sprouts so they crisp instead of going soft.
• One glass container, minimal cleanup. Season, cook, and serve from the same dish. The crisper plate and CleanCrisp glassware are dishwasher safe.
• Weeknight fast. From bag to plate in about 20 minutes, start to finish.
• Low oil, big flavor. A little over a tablespoon of oil is all it takes for restaurant-style caramelized edges.
• Endlessly adaptable. Balsamic, parmesan, bacon, honey-sriracha — the base recipe takes every topping beautifully.

Ingredients Needed

• Fresh Brussels sprouts: Trimmed and halved for crisping
• Olive oil or avocado oil: To coat evenly
• Kosher salt: To season and enhance the flavor
• Black pepper: For a subtle warm, peppery bite
• Garlic powder: For savory depth in every bite

Optional finishing touches:

• Grated parmesan: For salty, nutty, golden finishing flavor
• Balsamic glaze: For a sweet, tangy caramelized drizzle
• Honey and red pepper flakes: For sweet heat
• Lemon Juice: A squeeze of fresh lemon for bright acidity

Equipment

• Ninja Crispi or Ninja Crispi Pro (4-qt glass container with crisper plate + PowerPod)
• Mixing bowl
• Tongs or a spatula

How to Make Brussels Sprouts in the Ninja Crispi

Step 1: Prep the sprouts

Trim the dry stem end off each Brussels sprout and pull off any loose or yellowed outer leaves. Cut each sprout in half lengthwise through the stem. Don’t toss the loose leaves — throw them in too, because they crisp into little chip-like flakes that everyone fights over.

For even browning, keep the sprouts a uniform size. Halve any large ones again into quarters so they cook at the same rate.

Step 2: Season

Add the halved sprouts to a bowl. Drizzle with olive oil, then sprinkle on the salt, pepper, and garlic powder. Toss until every piece has a light, even coat. Oil is what carries the seasoning and drives the crisping, so don’t skip it — but don’t drown them either.

Step 3: Load the Ninja Crispi

Set the crisper plate inside the 4-quart glass container. Add the sprouts and spread them into as even a layer as you can, ideally cut-side down for maximum caramelization. A little overlap is fine; you’ll toss them partway through. Lock the PowerPod into place on top.

Step 4: Air fry on Max Crisp

Press MODE to select Max Crisp and set the timer to 14 minutes. At the 8-minute mark, lift off the PowerPod, give the sprouts a good toss or shake so the edges rotate, and spread them back out. Return the pod and finish cooking.

Step 5: Check and finish

The sprouts are done when the outsides are deep golden-brown and crackly and a fork slides easily into the centers. Want them extra dark and crispy? Add 2–3 more minutes and check again.

Toss with your finishing touches — parmesan, a drizzle of balsamic glaze, or honey and chili flakes — and serve immediately while they’re at peak crunch.

Tips for the Crispiest Brussels Sprouts

• Cut-side down matters. The flat face against the crisper plate gives you that caramelized, almost-fried surface.
• Don’t overcrowd. Doubling the batch? Cook in two rounds. Crowding traps steam and you’ll get soft, pale sprouts instead of crisp ones.
• Dry them well. If you rinse your sprouts, pat them completely dry before oiling. Surface water is the enemy of crispiness.
• Add cheese at the end. Parmesan added before cooking can scorch — toss it on in the last 2 minutes or right after cooking.
• Frozen sprouts work too. No thawing needed; add 4–6 minutes to the cook time and expect them slightly less crisp than fresh.

Flavor Variations

• Balsamic parmesan: Finish with balsamic glaze and a heavy hand of grated parmesan.
• Honey sriracha: Whisk 1 tbsp honey with 1 tsp sriracha and toss the hot sprouts in it.
• Bacon lover’s: Add chopped raw bacon to the container with the sprouts; the rendered fat crisps everything beautifully.
• Garlic parmesan: Extra garlic powder in the seasoning, parmesan and fresh parsley at the finish.
• Maple Dijon: Toss cooked sprouts with 1 tbsp maple syrup mixed with 1 tsp Dijon.

How to Store and Reheat

• Fridge: Store leftovers in an airtight container for up to 4 days.
• Reheat: Pop them back in the Ninja Crispi on the Recrisp setting for 3–4 minutes to bring back the crunch. Skip the microwave — it’ll make them soft.
• Freezing: Not recommended once cooked; they lose their texture.

Frequently Asked Questions

What temperature do you cook Brussels sprouts in the Ninja Crispi?

The original Ninja Crispi uses preset modes rather than a manual temperature dial. Use the Max Crisp setting, which runs the PowerPod at its highest heat (up to 450°F of superheated air) for the crispiest results. On the Crispi Pro, which has a manual dial, set it to 425–450°F.

How long do Brussels sprouts take in the Ninja Crispi?

Fresh halved Brussels sprouts take about 12–15 minutes on Max Crisp, tossed once halfway through. Add 4–6 minutes if you’re cooking from frozen, or a couple extra minutes if you like them very dark and crunchy.

Do you need to boil or steam the sprouts first?

No. Fresh sprouts go straight into the Ninja Crispi raw. The hot circulating air both cooks the inside and crisps the outside in one step.

Can you cook frozen Brussels sprouts in the Ninja Crispi?

Yes. Add them frozen — no thawing needed — and increase the cook time by 4–6 minutes. They’ll be a touch less crisp than fresh but still delicious.

Why are my Brussels sprouts soggy?

Almost always one of three things: too much water on the sprouts, too little oil, or overcrowding the container. Pat them dry, coat them lightly in oil, and cook in a single layer with room around each piece.

How many Brussels sprouts fit in the Ninja Crispi?

The 4-quart container comfortably handles about 1 pound of halved sprouts in a single layer. For larger amounts, cook in batches so they stay crisp.
