Cut the broccoli heads into florets and mince the garlic.
Place the broccoli florets in a large bowl or a sealable bag. Add the minced garlic, olive oil, salt, and black pepper. Toss or shake until the broccoli is evenly coated.
Arrange the broccoli in a single layer in the air fryer basket or tray, ensuring there is space between pieces for proper air circulation.
Set the air fryer to 400°F and cook the broccoli for 8–10 minutes, shaking the basket or turning the florets halfway through to ensure even cooking. The broccoli should be tender-crisp and lightly browned when done.
While the broccoli is cooking, zest and juice the lemon. Transfer the cooked broccoli to a serving dish. Drizzle the lemon juice over the broccoli, sprinkle with lemon zest, and top with grated Parmesan cheese. Serve immediately.
Notes
Spicy Kick: Add 1/4 teaspoon red pepper flakes or 1/8 teaspoon cayenne pepper to the olive oil mixture.
Herbs: Sprinkle 1/2 teaspoon dried thyme, rosemary, or oregano over the broccoli before cooking.
Cheese Lovers: Substitute the Parmesan with 1/2 cup shredded cheddar, mozzarella, or crumbled feta cheese.
Asian-inspired: Toss the broccoli with 1 teaspoon soy sauce and 1/2 teaspoon sesame oil before cooking.
Savory & Sweet: Drizzle 1 teaspoon honey or 1 teaspoon maple syrup over the cooked broccoli.
