Air Fryer Green Beans Casserole (Healthy and Tasty)

An easy Christmas side dish is the air fryer green bean casserole. 

It is simple to make, incredibly creamy, and topped with perfectly fried onions for crispness. All year long, you will desire it. 

I don’t recall having this great casserole with our holiday meals, but it has since established itself as a seasonal staple in my home.

The aromas of the Thanksgiving meal, which includes turkey, stuffing, dinner rolls, and of course, green bean casserole, flood the home. 

Just thinking about those crunchy onions makes me hungry. We slightly alter the fundamental recipe because we prefer ours with a little more crispy topping.

Ingredients You Need to Make Air Fryer Green Beans Casseroles

To make this wonderful side dish recipe, you just need a few basic ingredients. 

Most of the ingredients may already be in your pantry, but if not, just stop by the grocery store and you’ll be all set to enjoy this festive staple.

Soup/coconut creamThe simple creamy basis for these beans comes from a can of condensed cream of mushroom soup. These beans would also go well with a can of cream of chicken soup or cream of potato soup.
Green beansFor this recipe, use fresh yellow, green, or French beans. In a pinch, frozen beans might also suffice. Make careful to cook from frozen, though.
VariationsAfter removing the dish from the air fryer, top it with some blanched slivered almonds or cranberries.
Soy sauceThe dish gains umami flavor from the soy sauce. It’s amazing how much of a difference even a tiny amount of soy sauce can make! It boosts the flavor, and I believe that is one reason why this side dish has endured for so long.
French fried onionsThese give it a great flavor and a crunchy coating on top.
SeasoningAvoid adding salt! There is already plenty of salt in this dish between the soup and soy sauce. But adding some black pepper is an excellent idea.
MilkThe milk is used to thin out the soup and create a creamy sauce.

How to Make Air Fryer Green Beans

  1. When using fresh green beans, you must wash, trim the ends of the stems, and blanch them. 
  2. They should be cooked for about 2 minutes in a large pot of boiling water to blanch them. 
  3. Just drain the cans if you’re using canned green beans. There is no need to defrost frozen beans. 
  4. Mix both milk and cream of mushroom soup in a bowl. For nostalgic reasons, I enjoy using my mother’s Corning bowl from the 1970s, which is bright gold. 
  5. To make a smooth sauce, combine everything and mix out any lumps. Then stir once more after adding the soy sauce.
  6. Finally, air-fried everything at 340°F/171°C for about 15 minutes, or until everything is well cooked and mixed. Enjoy warm servings!
  7. In the bowl containing the soup mixture, add the beans and half of the fried onions. Stir everything together and season with pepper.

Can You Use Frozen or Canned Green Beans?

Frozen: Green beans can be used frozen. Simply disregard the timing I’ve provided for fresh green beans. Green beans that are frozen just require minor cooking or a warming-up process.

To prepare frozen green beans to your desired texture, air-fried them until they are warmed through. Proceed with the recipe after that. 

Canned: Green beans can be used in canned form. Green beans should be added to the air fryer cooking plate after the can’s water has been completely drained.

At 360°F for approximately 4 minutes, reheat the green beans in the can. When you add the cream of mushroom combination to the green beans in Step 3 of the recipe, continue with the steps from there.

Can You Make Green Beans Casserole Ahead of Time?

Every Christmas season, I find myself designing a menu that includes just as many dishes that can be prepared in advance as day-of meals. 

Nothing is simpler than transferring your prepared casserole from the refrigerator to the oven without creating a mess for the holidays. This casserole can simply be prepared the night before and stored in the refrigerator until cooking time. 

If so, remove the dish from the refrigerator about 30 minutes before cooking it so it can gradually come to room temperature. Then, quickly mix it before placing it in the air fryer.

Additionally, you might need to increase the cooking time by a few minutes. Although it’s quick to cook, this casserole does not store or thaw well. 

When vegan green bean casserole is refrigerated, it keeps for approximately 3 to 4 days before the beans start to soak up too much liquid and turn mushy. However, the sauce makes this a fantastic addition to your sandwich leftovers the next day!

Before cooking, you must trim the ends of the beans.

While many of my friends like to add a little something more to their casserole, I prefer to keep mine plain with just the essentials. 

The fried onions on top are by far the most well-liked addition. These can be made yourself or purchased from a business. I add the sautéed onions to mine instead of the fried chunks since I like them better.
