A quick and easy recipe for crispy smashed Brussels sprouts cooked in an air fryer, tossed with Parmesan cheese and fresh lemon for a healthy and flavorful snack or side dish.

Ingredients

Scale
  • 1 pound (450 g) Brussels sprouts, trimmed and halved
  • 2 tablespoons extra virgin olive oil
  • 1/4 cup (25 g) finely grated Parmesan cheese
  • 1 medium lemon, juiced and zest reserved
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt (sea salt flakes recommended)
  • 1/4 teaspoon freshly ground black pepper
  • Pinch of red pepper flakes (optional)

Instructions

  1. Rinse about 1 pound (450 g) of Brussels sprouts under cold water. Trim the stem ends and slice each sprout in half lengthwise. Pat dry thoroughly with a clean towel to avoid sogginess.
  2. Place the halved sprouts cut-side down on a baking sheet or sturdy plate. Using a potato masher or the bottom of a heavy glass, gently press down on each sprout until it’s flattened but still holds together.
  3. Transfer the smashed sprouts to a mixing bowl. Drizzle with 2 tablespoons (30 ml) of extra virgin olive oil, then sprinkle 1/2 teaspoon garlic powder, 1/2 teaspoon salt, 1/4 teaspoon freshly ground black pepper, and a pinch of red pepper flakes if using. Toss gently to coat evenly.
  4. Preheat air fryer to 375°F (190°C) and let it warm up for about 3 minutes.
  5. Arrange the seasoned sprouts in a single layer in the air fryer basket, cut side up if possible, making sure they don’t overlap. Cook for 12-15 minutes, flipping halfway through (at about 7 minutes) to get an even golden crust.
  6. When the sprouts are crispy and tender, transfer them to a serving bowl. While still hot, toss with 1/4 cup (25 g) finely grated Parmesan cheese, the zest of 1 lemon, and juice of half to a whole lemon (to taste). Stir gently to combine.
  7. Serve immediately for best texture and flavor. Optionally, sprinkle a bit more Parmesan or lemon zest on top.

Notes

If you don’t have an air fryer, roast smashed sprouts in a conventional oven at 425°F (220°C) for 20-25 minutes, flipping halfway. Pat Brussels sprouts dry thoroughly to ensure crispiness. Smash gently to increase surface area without breaking apart. Cook in batches if air fryer basket is small to avoid overcrowding. Toss with Parmesan and lemon immediately after cooking for best flavor. Store leftovers in an airtight container in the refrigerator for up to 2 days and reheat in air fryer or oven to restore crispiness.
