Air Fryer Roasted Vegetables
If you want to know exactly how long and at what temperature to cook vegetables in the air fryer so they turn out golden on the outside and tender on the inside without some overcooking while others stay raw, here’s the full table by vegetable type — the most common mistake is mixing vegetables with very different cooking times, and here’s how to avoid it.

Time and Temperature for Air Fryer Roasted Vegetables (Quick Table)
| Vegetable Type | Temperature | Approximate Time |
|---|---|---|
| Zucchini, mushrooms, cherry tomatoes | 190°C (375°F) | 8-10 min |
| Bell pepper, eggplant, onion | 190°C (375°F) | 12-15 min |
| Broccoli, cauliflower, Brussels sprouts | 200°C (390°F) | 15 min |
| Carrot, sweet potato, potato, beetroot | 200°C (390°F) | 20 min |
Vegetables fall into two broad groups: fast-cooking ones (higher water content, soften quickly) and slow-cooking ones (denser, need more time). Mixing both groups without accounting for this is the number one cause of an uneven result.
Why Do Some Vegetables Take So Much Longer Than Others?
The difference comes down to each vegetable’s density and water content. Zucchini softens in 10 minutes because it has a lot of water, while carrot needs twice as long because it’s much denser. That’s why, if you mix them all in the same batch without adjusting, the zucchini overcooks while the carrot is still hard.
Ingredients
- 500 g (1.1 lb) mixed vegetables (bell pepper, zucchini, onion, broccoli, or whichever you prefer)
- 1-2 tablespoons extra virgin olive oil
- Salt, to taste
- Black pepper, to taste
- Herbs or spices, to taste (oregano, rosemary, paprika)
- Lemon juice (optional, for a finishing touch)
How to Prepare the Vegetables Before Air Frying
- Cut all the vegetables into similarly sized pieces within each group, so they cook evenly.
- Mentally separate the fast-cooking vegetables (zucchini, mushrooms, tomatoes) from the slow-cooking ones (carrot, broccoli, onion), since they’ll go into the air fryer at different times.
- Toss the vegetables with the oil, salt, pepper, and whichever spices you prefer, mixing well until they’re all lightly coated.
Why You Need to Add the Hard Vegetables Before the Soft Ones
If you put all the vegetables in at once, the fast-cooking ones (zucchini, mushrooms) will overcook long before the slow-cooking ones (carrot, broccoli) are ready. The solution is to start cooking with just the hard vegetables and add the soft ones several minutes later, so both finish at the same time.
Step-by-Step: Air Fryer Roasted Vegetables
- Preheat the air fryer to 190-200°C (375-390°F) for 3 minutes.
- Cut all the vegetables into similarly sized pieces within each group.
- Toss the slow-cooking vegetables (carrot, broccoli, onion) with part of the oil and the spices.
- Place them in the basket and cook for 8-10 minutes.
- Meanwhile, toss the fast-cooking vegetables (zucchini, mushrooms, bell pepper) with the rest of the oil.
- Add these vegetables to the basket along with the ones already cooking and mix well.
- Cook for 8-10 more minutes, tossing or shaking the basket halfway through this second stretch.
- If using cherry tomatoes, add them only in the last 5 minutes, since they cook very quickly.
- Check doneness: the vegetables should be tender and slightly golden at the edges.
- Serve hot, with a squeeze of lemon juice on top if you want a fresh finishing touch.

How Much Oil Should You Use So the Vegetables Don’t Turn Out Greasy?
1-2 tablespoons of oil for the whole recipe is usually enough. If you use too much, the vegetables end up frying instead of roasting, and the result turns soft and greasy instead of golden and textured.
How to Tell When the Vegetables Are Done
The vegetables should be tender when pierced with a fork, with the edges slightly golden or toasted. Zucchini and bell pepper should give easily; carrot and broccoli should feel soft without falling apart.
Common Mistakes When Making Air Fryer Roasted Vegetables (and How to Avoid Them)
- Some vegetables end up raw and others overcooked → the most common mistake; it’s fixed by separating the vegetables by cooking time and adding them at different points, not all at once.
- They turn out soft and greasy → usually from too much oil; 1-2 tablespoons for the whole recipe is more than enough.
- They cook unevenly inside the basket → happens when you don’t toss or shake the basket halfway through cooking; a simple shake around the 7-8 minute mark fixes the problem.
- Cherry tomatoes burst or shrivel up too much → add them only in the last 5 minutes, since they cook much faster than the rest of the vegetables.
Frequently Asked Questions About Air Fryer Roasted Vegetables
Can you mix all the vegetables in the same batch? You can, but it’s worth keeping their cooking times in mind: add the slow-cooking ones first (carrot, broccoli, onion) and the fast-cooking ones (zucchini, mushrooms) several minutes later, so they all finish at the same time.
How much oil is needed for air fryer roasted vegetables? 1-2 tablespoons for the whole recipe (about 500 g / 1.1 lb of vegetables) is enough. Using more oil than necessary makes the vegetables fry instead of roast, losing that characteristic golden texture.
Why do my vegetables turn out soft instead of golden? It’s almost always from too much oil or from overcrowding the basket with too many vegetables, which prevents hot air from circulating well and achieving that golden effect.
Do you need to toss the vegetables during cooking? Yes, it’s recommended to shake the basket or toss halfway through, since otherwise the vegetables at the bottom stay softer and the ones on top get too toasted.
How long do frozen vegetables take in the air fryer? Frozen vegetables usually need a few extra minutes compared to fresh ones, since they start at a much lower temperature. There’s no need to thaw them first — just adjust the time by adding 3-5 extra minutes.
Which vegetables work best together in the same batch? Bell pepper, zucchini, onion, eggplant, and mushrooms pair well together since they have similar cooking times. If you add carrot or broccoli, put them in earlier, since they need more time.
Can you use olive oil, or is another type of oil better? Extra virgin olive oil works well for most air fryer recipes, although if you’re aiming for very high temperatures over a long time, oils with a higher smoke point (like sunflower oil) hold up better without affecting the flavor.
Why do some vegetables turn out raw while others are overcooked? It’s the most common mistake, caused by mixing vegetables with very different cooking times from the start. The solution is to stagger when each vegetable goes in based on how dense it is, starting with the hardest ones.
Can you add cheese or nuts to roasted vegetables? Yes, it’s a common way to add an extra touch: you can add shredded cheese or nuts (like pine nuts or walnuts) in the last few minutes of cooking, so they brown without burning.
How many calories does a serving of air fryer roasted vegetables have? It depends on the vegetables used, but with 1-2 tablespoons of oil for the whole recipe, a serving usually comes to between 80 and 120 kcal, making it one of the lightest side dishes you can prepare in the air fryer.
