- A quick pre-soak or steam trick softens the core so sprouts cook evenly and don’t dry out.

Ingredients
Method
- Prep the sprouts: Rinse, trim the stem ends, and remove any yellowed outer leaves. Halve lengthwise. If your sprouts are very large, quarter them so they cook evenly.
- Optional quick soak for tenderness: Place halved sprouts in a bowl of hot tap water for 5 minutes, then drain and pat very dry. This helps soften the core without overcooking the edges.
- Season: In a large bowl, toss sprouts with oil, salt, pepper, and garlic powder until evenly coated. Add lemon zest if using.
- Preheat the air fryer: Set to 375°F (190°C) for 3 minutes. A hot basket gives better browning.
- Arrange in the basket: Place sprouts cut-side down in a single layer. Do not overcrowd. Work in batches if needed.
- Air fry: Cook at 375°F (190°C) for 10 to 12 minutes total, shaking the basket or stirring at the 6-minute mark. For extra char, bump to 390°F (200°C) for the last 2 minutes.
- Finish: Transfer to a bowl. Toss with lemon juice and, if you like, a light drizzle of honey or maple syrup. Adjust salt and pepper. Add red pepper flakes or smoked paprika if desired.
- Serve right away: They’re best hot and crispy. If making multiple batches, keep finished sprouts on a sheet pan in a 200°F (95°C) oven to stay crisp.
How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Reheat to re-crisp: Air fry at 350°F (175°C) for 3 to 5 minutes, shaking once. Or use a hot skillet with a touch of oil for 2 to 3 minutes. Avoid the microwave if you want to keep the crunch.
- Freeze: Not ideal.
Freezing softens the texture and they won’t re-crisp well.
Why This is Good for You
- Nutrient-dense: Brussels sprouts are rich in vitamin C, vitamin K, and folate.
- High in fiber: Supports digestion and helps you feel satisfied.
- Antioxidants and plant compounds: Contain glucosinolates and other compounds linked to cellular health.
- Light on oil: Air frying uses far less oil than deep frying, cutting calories while keeping great texture.
Common Mistakes to Avoid
- Crowding the basket: If sprouts touch or overlap too much, they steam and turn soggy. Cook in batches for even crisping.
- Skipping the dry step: Wet sprouts won’t brown. After rinsing or soaking, pat very dry before seasoning.
- Using too much oil: A light coating is all you need.
Extra oil can make them heavy and smoky.
- Uneven sizes: Large halves and tiny halves cook at different rates. Cut to similar sizes for consistent results.
- Not checking early: Air fryers vary. Start checking at 8 to 9 minutes to prevent burning, especially with loose leaves.
Recipe Variations
- Balsamic-Parmesan: Toss hot sprouts with 1 tablespoon balsamic glaze and 2 to 3 tablespoons freshly grated Parmesan.
Add cracked black pepper.
- Honey-Mustard: Mix 1 tablespoon Dijon with 1 tablespoon honey and 1 teaspoon olive oil. Toss with hot sprouts and a squeeze of lemon.
- Garlic-Lemon: Add 1 minced garlic clove and extra lemon zest before air frying. Finish with parsley and more lemon juice.
- Smoky Maple Bacon: Air fry 2 to 3 slices of chopped bacon until crisp, remove, then cook sprouts in the rendered fat plus 1 teaspoon oil.
Toss with 2 teaspoons maple syrup and the bacon.
- Spicy Chili-Crunch: Finish with chili crisp or a mix of sesame oil, soy sauce, and red pepper flakes. Sprinkle toasted sesame seeds.
- Pecan and Cranberry: Toss cooked sprouts with toasted pecans, dried cranberries, and a touch of orange zest for a holiday vibe.
FAQ
Do I need to soak Brussels sprouts first?
A short soak in hot water is optional but helpful. It softens the core so the centers cook through as the leaves crisp.
If skipping the soak, just make sure to halve any large sprouts.
What temperature is best for air frying Brussels sprouts?
375°F (190°C) gives you a great balance of tender centers and crispy edges. For extra char, raise to 390°F (200°C) in the last couple of minutes.
How do I keep them from getting bitter?
Use fresh sprouts, trim the stem and any tough outer leaves, and add acidity. A squeeze of lemon juice or splash of vinegar balances any bitterness.
A touch of honey or maple also helps.
Can I use frozen Brussels sprouts?
Yes, but results vary. Thaw, drain well, and pat very dry before seasoning. Expect slightly softer texture and less charring than fresh.
How much oil should I use?
About 1 to 1.5 tablespoons per pound is ideal.
Enough to help browning, not so much that they turn greasy.
Why are my Brussels sprouts burning on the outside but hard inside?
They’re likely too large or too dry. Cut large sprouts into quarters, consider the quick soak, and reduce the temperature slightly while extending cook time by a couple of minutes.
Can I double the recipe?
Yes, but cook in batches. Keep finished sprouts warm in a low oven so everything stays crisp until serving.
What should I serve these with?
They pair well with roasted chicken, salmon, pork chops, or grain bowls.
They also make a great taco or salad topper.
