How to Make Air Fryer Green Bean Casserole with Step-by-Step Instructions
A complete printable recipe and the measurements in both US customary and metric are available in the recipe card below.
Begin by setting your air fryer to preheat at 350°F/180°C. Proper preheating ensures an even cooking temperature, which is crucial for achieving that creamy texture and golden brown finish.
Creating the Casserole Mixture
For this step, you’ll need to first boil your green beans until they reach a balance between tenderness and crispness. Once done, drain the beans and add green beans to a casserole dish.
Next, add cream of mushroom soup (many recipes call for chicken soup or chicken broth, but this is a vegetarian-friendly recipe), milk, a cup of crispy onions, and some sharp cheddar cheese (parmesan cheese works wonderfully, too) to the baking dish, along with salt and black pepper.
Stir the soup mixture ingredients well to get a consistent and creamy green bean mixture.
Baking in the Air Fryer
Place your casserole dish in the air fryer basket and air fry it until you notice it starting to bubble, which should take around 12 minutes, giving it a gentle stir midway through (around 6 minutes).
After the initial baking, remove the dish, give it another mix, and sprinkle the remaining fried onions on top.
Return the dish to the air fryer and cook until the onions are golden brown, typically taking another 2-3 minutes.
Once done, remove your air fryer green bean casserole from the air fryer and let it sit for a couple of minutes before serving.
This short rest allows the flavors to meld and the creamy sauce to thicken just a bit more, ensuring every bite is a perfect blend of creaminess and crunch.
Serve this creamy green bean casserole recipe with all of the trimmings!

Notes
- Green beans: When deciding between fresh green beans, canned, or frozen green beans, always opt for fresh whenever possible. Fresh beans provide a superior texture and flavor. However, if using frozen, ensure they’re fully thawed and well-drained to avoid a watery casserole. For canned green beans, make sure they are well-drained as well.
- Can I use fresh mushrooms instead of mushroom soup? Unfortunately for this recipe, condensed mushroom soup is needed for the creaminess and extra flavor.
- Turn up the flavor: While the basic ingredients already promise a delicious dish, consider adding a sprinkle of garlic powder or onion powder for an extra layer of depth. A dash of vegetarian Worcestershire sauce or soy sauce can also give the creamy mushroom sauce a unique twist.
- Perfect onion topping: The key to those irresistible crispy fried onions is ensuring your air fryer is at the right temperature. Watch them closely during the final minutes of cooking to avoid over-browning. We love the French’s brand Crispy French Fried Onions for this recipe.
- Other additions: While the recipe is perfect as it is, don’t hesitate to customize it to your liking. Some may prefer adding chopped veggie bacon for a smoky touch or mixing in sour cream for a richer texture. Experiment and find what works best for you and your family!
- Make this dish ahead: Yes, you can make this green bean casserole ahead and refrigerate it. Just be sure to save the crispy onion topping and add it right before reheating to retain its crunch.
- Baking dish: Oven-safe dishes are perfect for baking in an air fryer! Make sure that your baking dish fits the air fryer basket before you begin cooking.
- Storage instructions: Cool the air fryer green bean casserole down completely before storing in an airtight container in the fridge for up to 4 days. For the best flavor and texture, it’s recommended to consume within the first two days.
- Reheat: Reheat your casserole in the air fryer. This method ensures the topping remains crispy and the casserole retains its creamy consistency. Avoid microwaving, as it might make the dish a bit soggy. If your onions have turned soft in the fridge and won’t crisp back up, sprinkle some fresh crispy onions over the casserole.
