Creamy, savory, and topped with crispy bacon, this Air Fryer Green Bean and Bacon Casserole is a comforting side dish made faster and easier in the air fryer. Tender green beans are coated in a rich mushroom cream sauce, blended with cheese and seasonings, then finished with crunchy bacon and a golden topping. It delivers all the flavor of a traditional holiday casserole without heating up the oven.
The air fryer creates a beautifully bubbly casserole with crispy edges and perfectly cooked green beans in less time than conventional baking. Because the circulating hot air cooks evenly, the sauce thickens quickly while the bacon becomes irresistibly crisp. This makes it an ideal recipe for busy weeknights, holiday dinners, potlucks, or family gatherings when oven space is limited.
One of the best features of this recipe is its flexibility. Fresh, frozen, or canned green beans can all work well depending on what you have available. You can also customize the casserole by adding sautéed onions, mushrooms, garlic, or shredded cheddar cheese for even more flavor and texture. The smoky bacon pairs perfectly with the creamy sauce, giving every bite a rich and satisfying taste.
Serve this casserole alongside roasted chicken, turkey, steak, or holiday favorites for a hearty and comforting meal. The crispy topping and creamy filling make it a crowd-pleasing side dish that feels both classic and modern thanks to the quick air fryer preparation.

Ingredients
For the Casserole
- 1 pound fresh green beans, trimmed and cut in half
- 6 slices bacon, cooked and crumbled
- 1 can (10.5 oz) cream of mushroom soup
- ½ cup milk
- 1 cup shredded cheddar cheese
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- ½ teaspoon salt
For the Topping
- ½ cup crispy fried onions
- 2 tablespoons grated Parmesan cheese
Instructions
Step 1: Prepare the Green Beans
Bring a pot of water to a boil and blanch the green beans for 3–4 minutes until slightly tender. Drain and rinse with cold water to stop the cooking process.
Step 2: Cook the Bacon
Cook the bacon in a skillet until crispy, then crumble into small pieces. Set aside.
Step 3: Make the Sauce
In a large bowl, combine cream of mushroom soup, milk, cheddar cheese, garlic powder, onion powder, salt, and black pepper. Stir until smooth.
Step 4: Assemble the Casserole
Add the green beans and half the bacon to the sauce mixture and toss until evenly coated.
Transfer everything into a greased air-fryer-safe baking dish or cake pan. Sprinkle the remaining bacon, fried onions, and Parmesan cheese over the top.
Step 5: Air Fry
Preheat the air fryer to 360°F (182°C) for 3 minutes.
Place the casserole dish into the air fryer basket and cook for 14–16 minutes, or until hot and bubbly with a golden crispy topping.
Step 6: Serve
Allow the casserole to rest for 5 minutes before serving so the sauce thickens slightly.
