Prep the sprouts: Rinse, trim the stem ends, and peel off any yellow or damaged leaves.
Halve lengthwise. If a sprout is very large, quarter it so everything cooks evenly.
Season simply: In a large bowl, toss sprouts with olive oil, salt, pepper, garlic powder, onion powder, and smoked paprika. Make sure every piece gets a light, even coat.
Preheat the air fryer: Set to 390–400°F (200°C).
Preheating helps you get crispier edges from the start.
Arrange in the basket: Spread sprouts in a single layer, cut side down. If your air fryer is small, cook in two batches. Crowding leads to steaming instead of crisping.
Air fry: Cook for 10–12 minutes, shaking the basket halfway.
You’re aiming for browned edges and fork-tender centers. Add 1–2 minutes if needed for extra char.
Mix the glaze: While the sprouts cook, whisk sweet chili sauce, soy sauce, rice vinegar or lime juice, and sriracha (if using). Taste and adjust for sweetness, salt, and heat.
Toss to coat: Transfer hot sprouts to a bowl and pour on the glaze.
Toss gently until every sprout is glossy. The residual heat will help the sauce cling.
Finish and serve: Drizzle with a little toasted sesame oil if you like. Top with green onions and sesame seeds.
Serve with lime wedges for a bright squeeze at the table.
