Method
- Preheat your air fryer to 200°C (400°F) so it's ready to go.
- Trim the ends off your fresh green beans and give them a quick rinse under cold water. Pat them completely dry with a kitchen towel — this helps them crisp up during roasting.

10 Practical Q&As About Air Fryer Roasted Green Beans
1. Can I use frozen green beans?
Use fresh green beans for the best snap and flavor. Avoid dull, limp beans, as they won’t crisp well.
2. Should I toss the beans with oil before roasting?
Yes, but thaw and dry them thoroughly first. Frozen beans release more moisture and won’t crisp up as nicely.
3. Can I add seasoning before roasting?
Absolutely, a light toss with oil helps with browning and gives a nice crispy texture. Use a neutral oil like canola or a little olive oil.
4. How do I prevent them from burning?
Yes, sprinkle with salt, pepper, or even garlic powder before air frying. It helps the flavors penetrate during cooking.
5. What if my green beans are too soft after roasting?
Keep an eye on the beans, especially near the end. Shake the basket halfway through to promote even browning.
6. Can I roast other vegetables this way?
Check the cooking time and temperature. If they’re too soft, reduce the time slightly or lower the heat next time.
7. What’s a good dipping sauce for these beans?
Definitely. Broccoli, Brussels sprouts, and asparagus work well, just adjust the cooking time accordingly.
8. How long do leftovers keep?
A simple lemon aioli or a balsamic glaze can add a bright, tangy touch. Keep it light so it doesn’t overpower the beans.
9. Can I make these ahead for a party?
Store in an airtight container in the fridge for up to 2 days. Reheat briefly in the air fryer for crispness.
Once you get the hang of it, these roasted green beans become a regular in your snack rotation. They’re perfect for munching on during a movie or tossing into salads for a warm crunch.
It’s funny how a simple kitchen hack can make vegetables feel new again—more exciting, even. And in this season of quick, seasonal bites, they feel just right, a little bit fresh, a little bit roasted, and totally addictive.
