Air Fryer Brussels Sprouts (Crisp Leaves, Tender Centres)

CrispyAir Kitchen · Updated October 22, 2026 · Air fryer recipes with exact times & temperatures

Brussels sprouts take 15–18 minutes at 375°F (190°C), halved and shaken twice, until the outer leaves shatter crisp and the centres are tender and sweet. The air fryer is the sprout's best friend — it does what the oven promises but faster, crisping the loose leaves into chips while the cut faces caramelise. A balsamic finish in the final minutes (never at the start — it burns) completes the conversion of every sprout sceptic at the table.

Ingredients

• 1 lb (450 g) Brussels sprouts
• 1 1/2 tbsp olive oil
• 3/4 tsp fine sea salt
• 1/2 tsp black pepper
• 1/2 tsp garlic powder
• 1 tbsp balsamic vinegar or glaze, plus 1 tsp honey (optional finish)
• Grated Parmesan, to serve (optional)

Method

1. Trim the stem ends and halve the sprouts lengthwise. Peel away any yellowed outer leaves — but keep the loose leaves that fall; they become the crispiest part.
2. Toss with the oil, salt, pepper and garlic powder, working the seasoning onto the cut faces.
3. Preheat the air fryer to 375°F (190°C) for 3 minutes. Spread the sprouts in a single layer, cut side up where they land that way.
4. Cook 8 minutes, shake hard, then cook 7–10 minutes more until the edges are deeply browned, loose leaves are crisped dark, and a centre pierces tender.
5. Toss with the balsamic and honey while hot, scatter Parmesan if using, and serve immediately.

Tips that actually matter

• Bacon-fat route: a spoonful of the fat saved from our air fryer bacon, or chopped bacon cooked with the sprouts for the final 8 minutes — the holiday table version.
• Frozen sprouts: halve after 5 minutes of cooking (they soften enough to cut), then continue 10–12 minutes more. Season midway so it sticks.
• Very large sprouts should be quartered; the size of the piece, not the clock, decides doneness.

Why this recipe works

A sprout is a tiny cabbage of layered leaves, and heat treats each layer differently: the outer leaves dry and crisp into chips while the dense heart steams tender inside them. Halving doubles the caramelisable cut surface, which is where the bitter green flavour converts to nutty sweetness.

Variations to try

The same vegetables, new accents: smoked paprika and cumin for a Spanish lean; curry powder and a squeeze of lime; everything-bagel seasoning after cooking; Parmesan and lemon; or chilli crisp spooned over at the table.

What to serve with it

At the holiday table with the turkey breast, beside pork chops, or tossed warm through grains with feta.

Storage & reheating

Refrigerate up to 4 days. Reheat at 375°F (190°C) for 4 minutes to revive the leaves.

Frequently asked questions

Why are my sprouts bitter?

Undercooking, or old sprouts. Full caramelisation is what converts the bitter compounds to sweetness — cook until the edges are properly dark, not just warm.

Cut side up or down?

Mixed is fine in a basket fryer because the shaking redistributes them; the cut faces brown wherever they land against hot air and oil.

Can I cook sprouts whole?

Small ones, yes — add 3–4 minutes. Halving is better: more caramelised surface, faster and more even cooking.
