Preheat your air fryer. Set it to 390–400°F (200–205°C) for 3–5 minutes. A hot basket helps the veggies sear on contact.
Prep the veggies. Wash, dry well, and cut them into even, bite-size pieces.
Pat dry again to remove excess moisture. Dry veggies brown better.
Season generously. In a large bowl, toss the veggies with 1–2 tablespoons olive oil, 1 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon garlic powder, 1 teaspoon smoked paprika, and 1 teaspoon Italian seasoning. Add lemon zest for brightness.
Don’t overload the basket. Arrange veggies in a single layer for the best color. Work in batches if needed. Crowding = steaming, not grilling.
Air fry and shake. Cook for 8–12 minutes, shaking the basket halfway.
Thinner items (peppers, zucchini) cook faster; thicker ones (broccoli, mushrooms) need a touch longer. Aim for caramelized edges and tender centers.
Finish with acid and herbs. Right after cooking, splash with 1–2 teaspoons balsamic or red wine vinegar. Toss with chopped parsley or basil.
Taste and adjust salt.
Serve immediately. Add lemon wedges on the side. The heat brings out the citrus aroma and brightens every bite.
