Air Fryer Smashed Brussel Sprouts - Crispy, Garlicky, and Fast

Prep Time10 minutes
Cook Time18 minutes
Total Time28 minutes
Servings: 4 servings

Ingredients

  • 1.5 pounds Brussels sprouts, trimmed and halved if large
  • 2 tablespoons olive oil (plus a little more if needed)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder (or 2 cloves fresh garlic, minced)
  • 1/2 teaspoon onion powder (optional but nice)
  • 1/4 teaspoon red pepper flakes (optional, for heat)
  • 1/3 cup grated Parmesan (freshly grated works best)
  • Lemon wedges, for serving
  • Cooking spray (to prevent sticking)

Instructions

  • Par-cook the sprouts: Bring a pot of salted water to a boil. Add Brussels sprouts and cook for 6–8 minutes, until just fork-tender but not mushy. Drain well and pat dry. Drying is important for crisping.
  • Preheat the air fryer: Set it to 400°F (200°C) for 3–5 minutes. A hot basket helps with browning.
  • Toss with seasoning: In a large bowl, combine sprouts, olive oil, salt, pepper, garlic powder, onion powder, and red pepper flakes. Coat evenly.
  • Smash: Place the sprouts on a cutting board. Use the bottom of a drinking glass, a heavy jar, or a small skillet to press down gently until each sprout flattens to about 1/2 inch thick. Don’t overdo it—keep them in one piece.
  • Prepare the basket: Lightly spray the air fryer basket with cooking spray. Arrange the smashed sprouts in a single layer with a bit of space between them. Work in batches if needed.
  • Air fry, round one: Cook at 400°F for 8–10 minutes. They should start to brown and crisp at the edges.
  • Add Parmesan: Sprinkle the grated Parmesan over the sprouts. Return to the air fryer for 2–4 more minutes, until the cheese melts and turns golden.
  • Finish and serve: Transfer to a plate. Squeeze a little lemon over the top and taste for salt. Serve hot with your favorite dip.
