Preheat the air fryer to 390–400°F (200–205°C). A hot basket helps you get crisp edges right away.
If your model doesn’t preheat, let it run empty for 3–4 minutes.
Prep the vegetables evenly. Cut everything into similar sizes so they cook at the same pace. Tough veggies like carrots and sweet potatoes should be about 1-inch pieces; softer veggies like zucchini can be a bit thicker to avoid overcooking.
Pat dry for maximum crisp. Moisture is the enemy of browning. If you’ve rinsed your vegetables, blot them with a clean kitchen towel before seasoning.
Toss with oil and seasoning. In a large bowl, use about 1–1.5 tablespoons of oil per pound of vegetables.
Add salt, pepper, and your chosen spices. Coat thoroughly so every piece gets love.
Load the basket in a single layer. Don’t overfill. A little space around the vegetables lets the hot air circulate and crisp the edges.
Work in batches if needed.
Air fry and shake. Cook for 10–16 minutes depending on the veggies. Shake the basket or toss with tongs halfway through to ensure even browning.
Check doneness. You’re looking for caramelized edges and a fork-tender center. Softer vegetables (zucchini, peppers) may be done in 8–10 minutes; denser ones (carrots, sweet potatoes) often take 14–18 minutes.
Finish and serve. Taste and adjust salt.
Add a squeeze of lemon, a sprinkle of Parmesan, or fresh herbs. Serve hot as a side, toss into grain bowls, or top with a fried egg for a quick meal.
