Air Fryer Brussels Sprouts

Toss together Brussels sprouts and olive oil in a large bowl until thoroughly coated.

Preheat air fryer to 350°F for 6 minutes. Lightly coat basket with cooking spray. Add Brussels sprouts to basket, and cook until golden brown and crispy, 20 to 25 minutes, stirring halfway through cooking.

Meanwhile, trim both ends off lemon. Stand lemon on 1 end. Using a sharp knife, carefully cut peel and white pith away from lemon flesh, starting at the top end and moving down toward the bottom end; discard peel. Slice along each section, removing lemon segment from membrane; reserve lemon membrane and segments separately. Cut reserved lemon segments into small cubes to equal 1 1/2 tablespoons; set aside. Squeeze juice from reserved lemon membrane to equal 1 teaspoon. 

Transfer Brussels sprouts to a medium bowl, and toss with butter, thyme, lemon juice, and cubed lemon segments. Transfer Brussels sprout mixture to a platter, and sprinkle evenly with grated cheese; serve immediately.
