10 Practical Q&As About Air Fryer Roasted Green Beans

1. Can I use frozen green beans?

Use fresh green beans for the best crunch and flavor. They should be firm and bright green.

2. Can I use other beans?

Yes, but thaw and pat them dry to avoid sogginess. Frozen beans release more water, which can steam instead of roast.

3. What if my beans are bitter?

Absolutely, snap peas or asparagus work well too, but adjust cooking time as they might cook faster.

4. How do I prevent them from burning?

A quick blanch in boiling water for 30 seconds can reduce bitterness before roasting.

5. What’s the best oil for roasting?

Keep an eye on the beans in the last few minutes. Shake the basket for even cooking and check frequently.

6. Can I add seasoning beforehand?

A light spray of olive oil or avocado oil works best—just enough to coat without making them greasy.

7. How do I get crispy beans?

Yes, toss them with your preferred spices before roasting for more flavor, but go easy on salt; it draws out water.

8. How long do they last after roasting?

Avoid overcrowding the basket, and roast at a high temp (200°C/400°F) to promote crispness.

9. Can I make this in advance?

Eat them fresh for the best crunch, but they keep in the fridge for up to a day—reheat in the air fryer for crispiness.

10. What’s the key to perfect roasted green beans?

You can prep the beans ahead, but roast just before serving for maximum crunch.

Once they’re out of the air fryer, I like to toss the beans with a squeeze of lemon or a sprinkle of parmesan. It’s a simple upgrade that makes all the difference. These green beans are a reminder that small, easy dishes can hold a lot of personality.

And honestly, they’re so versatile. Serve them as a snack, a side, or toss into salads. They’re just happy green spears, roasted to perfection, waiting to be enjoyed.
