Air Fryer Roasted Vegetables

Roasted vegetables are one of those dishes where the method matters more than the recipe. The same zucchini that goes limp and pale in a crowded oven turns sweet, caramelized, and crisp-edged in an air fryer. High heat plus constant air circulation is exactly what vegetables want: moisture escapes fast, natural sugars caramelize, and edges brown before the centers turn to mush.

This recipe is a template as much as a recipe. The seasoning is simple and the technique works for almost any vegetable you have on hand, which makes it the perfect answer to the crisper drawer full of odds and ends. Thirty minutes, one basket, a side dish that goes with everything.

Why This Recipe Works

• Hot, moving air is ideal for vegetables. Moisture evaporates quickly, so vegetables roast instead of steam — that’s the difference between caramelized edges and a soggy pile.
• Uniform cuts cook uniformly. Cutting everything to roughly the same size means the zucchini and the carrots finish at the same time. No burnt bits, no raw bits.
• Oil is a browning agent, not a bath. A light, even coating helps vegetables brown and keeps seasoning stuck. More oil doesn’t mean more flavor — it means greasy vegetables.
• The shake replaces the flip. Shaking the basket halfway redistributes everything for even browning with zero fuss.
• Air fryer models vary. Wattage and basket size differ, so this recipe gives you a time range plus doneness cues. If you’re new to the appliance, our guide to using an air fryer covers preheating and batch cooking.

Ingredients

• 1 medium zucchini (about 200 g), cut into 3/4-inch half-moons — cooks quickly and caramelizes beautifully.
• 1 red bell pepper, cut into 1-inch pieces — sweetness and color.
• 1 small red onion, cut into wedges — the layers crisp into sweet, charred petals.
• 2 medium carrots (about 200 g), sliced 1/2-inch thick on the diagonal — denser, so cut thinner than the rest.
• 2 cups broccoli florets — the little florets get wonderfully crisp tips.
• 2 tablespoons olive oil — just enough for browning and seasoning adhesion.
• 1 teaspoon garlic powder — savory depth.
• 1 teaspoon Italian seasoning — a balanced herb base.
• 3/4 teaspoon fine sea salt — vegetables need confident seasoning.
• 1/2 teaspoon freshly ground black pepper
• 1 tablespoon balsamic vinegar (optional, added after cooking) — brightens everything.

Substitutions

• Vegetable swaps: Use any sturdy vegetables in roughly equal total volume (about 6–7 cups): cauliflower, Brussels sprouts (halved), butternut squash (1/2-inch cubes), green beans, or asparagus (add these in the last 6–8 minutes). Skip very watery vegetables like cucumber or raw tomatoes.
• Seasoning: Try smoked paprika + cumin for a warm profile, or za’atar for a Middle Eastern angle. Fresh herbs go on after cooking.
• Oil: Avocado oil or any neutral oil works. For an oil-free version, the vegetables will still cook but won’t brown as deeply.
• Vegan/gluten-free: This recipe is naturally both.

Equipment

Instructions

1. Cut everything evenly. This is the step that determines success. Cut the zucchini into 3/4-inch half-moons, the bell pepper into 1-inch pieces, the onion into wedges, the carrots into 1/2-inch diagonal slices, and break the broccoli into bite-size florets. Denser vegetables (carrots) go thinner; quick-cooking ones (zucchini) go chunkier.
2. Season. In a large bowl, toss all the vegetables with the olive oil until lightly and evenly coated. Sprinkle over the garlic powder, Italian seasoning, salt, and pepper, and toss again.
3. Preheat the air fryer. Set it to 400°F (200°C) and run for 3 minutes.
4. Cook in batches. Spread the vegetables in a single layer — cook in two batches if needed. Air fry at 400°F (200°C) for 12–15 minutes, shaking the basket well at the halfway mark, until the edges are browned and caramelized and the densest pieces are tender when pierced.
5. Finish. Transfer to a serving bowl, drizzle with balsamic vinegar if using, and serve warm.

Conventional oven alternative

Heat the oven to 425°F (220°C). Spread the seasoned vegetables on a large parchment-lined baking sheet — give them real space, using two sheets if needed — and roast for 25–30 minutes, flipping once halfway.

Recipe Scaling Notes

Vegetables shrink as they cook, so a “crowded” raw basket becomes a sad, steamed one. When scaling up, add batches, not layers — each batch takes the same 12–15 minutes. A good rule of thumb: one batch per 3–4 cups of raw vegetables. To recalculate quantities for your headcount, use our Recipe Scaler and read How to Scale Recipes Without Ruining Them.

Storage and Reheating

Refrigerate leftovers in an airtight container for up to 4 days. Reheat in the air fryer at 375°F (190°C) for 4–5 minutes to restore some crispness — the microwave makes them soft but they’re still tasty in grain bowls and wraps. Leftover roasted vegetables are excellent cold in salads.

Common Mistakes and Troubleshooting

• Soggy vegetables: The basket was overcrowded, or the vegetables went in wet. Dry them after washing, give them space, and cook in batches.
• Some burnt, some raw: Uneven cutting. Match piece sizes to cooking speed — dense vegetables thinner, quick ones chunkier.
• Bland despite seasoning: You probably under-salted, or seasoned before oiling so the spices slid off. Oil first, then season, then taste and adjust after cooking.
• Broccoli florets burn: The tiny floret tips char fast. Keep florets on the larger side, or add them 5 minutes into the cook.
• Sticking: Preheat the basket and make sure every piece has a light oil coating.

FAQ

Can I mix any vegetables together? Almost — just group by density. Root vegetables and squash need smaller cuts or a head start; quick-cooking vegetables like zucchini, peppers, and asparagus can join later in the cook.

Do I need to peel the vegetables? No, except for carrots if you prefer them peeled (a good scrub is fine). Skins add texture and nutrients.

Why are my vegetables steaming instead of roasting? Too much water and too little space. Pat vegetables dry after washing, don’t overcrowd, and make sure the air fryer is fully preheated.

Can I prep these ahead? Yes — cut the vegetables up to 2 days ahead and refrigerate in a sealed container (keep cut potatoes in water). Season and cook fresh for the best texture.

How do I keep leftover roasted vegetables from getting mushy? Cool them completely before refrigerating, store in a single layer if possible, and reheat in the air fryer rather than the microwave. To keep vegetables fresh for longer in general, our storage guide covers the best methods for each type.
