This Air Fryer Green Bean Casserole is the classic holiday side dish, made right in your air fryer: tender green beans in a creamy mushroom sauce, topped with crispy fried onions.
I've always loved green bean casserole for the holidays, but there isn't always room in the oven with the turkey and everything else. So I decided to make it in the air fryer, where I could save time and space.

Key Ingredients
Canned Green Beans: Use cut or French-style. Thawed frozen beans also work well.
Cream of Mushroom Soup: Go with low sodium so it doesn't get too salty.
Worcestershire Sauce: Soy sauce works too.
Heavy Cream: Thins the soup and makes it a little richer.
Black Pepper & Paprika: Try smoked paprika for a deeper taste.
French Fried Onions: The classic crispy topping.
How to Make Air Fryer Green Bean Casserole
In a large bowl, stir together everything except the French fried onions.
Spoon the mixture into a deep baking dish that fits in your air fryer basket. Air fry at 350°F for 10 minutes, stirring halfway through so it cooks evenly. Add the fried onions only at the end so they stay crisp, then air fry at 300°F for 3 more minutes.
Let it rest a few minutes before serving so the sauce thickens slightly.
Variations
- Use cream of chicken or celery soup instead of mushroom.
- Stir in sautéed mushrooms or garlic.
- Sprinkle parmesan over the fried onions before air frying for a cheesy finish.
- Sprinkle shredded cheddar cheese over the top.
- Swap the French fried onions for crispy fried jalapeños for a spicy version.
Top Tips
- Stir halfway through for even cooking.
- Add onions only at the end to keep them crisp.
- Let the dish rest a few minutes before serving to thicken slightly.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 5 days. Reheat in the air fryer at 300°F for 5-7 minutes to warm the casserole through and crisp the topping again.
Serve With...

Yes, but cook them first. Steam them on the stovetop for 5-7 minutes, then mix them in like you would the canned beans.
