Ingredients
Scale
For the Casserole:
- 1/2 cup whole milk
- 1/4 tsp ground black pepper
- 1 tsp soy sauce
- 1 can (10.5 oz) condensed cream of mushroom soup (Campbell’s recommended)
- 4 cups green beans (fresh, frozen, or canned; thawed if frozen)
For the Topping:
- 1 1/3 cups crispy fried onions (French’s brand recommended; divided)
Instructions
- Prepare Your Ingredients and Preheat Equipment: If using frozen green beans, thaw them fully and drain excess moisture. For fresh beans, trim ends, cut into 2-inch pieces, and blanch briefly in salted boiling water before draining. Canned beans should be well drained. Preheat your oven to 350°F (175°C) or an air fryer to the same temperature. Measure crispy fried onions, dividing into about 2/3 cup for mixing and 1/3 cup reserved for topping.
- Build the Creamy Soup Base: In a large mixing bowl, whisk the condensed cream of mushroom soup, whole milk, and soy sauce until smooth and fully combined. The soy sauce adds umami depth to the creamy base without excess saltiness.
- Combine Green Beans with Sauce and Seasonings: Add the prepared green beans, 2/3 cup fried onions, and 1/4 teaspoon ground black pepper to the creamy mixture. Gently fold together until green beans are evenly coated and fried onions distributed. Avoid overmixing to keep onions intact and crispy before baking.
- Transfer to Baking Dish and Initial Bake: Pour the green bean mixture into a 9×9-inch baking dish, spreading an even layer. Bake in the preheated 350°F oven for 25 minutes or air fryer for 10 minutes, until bubbly around the edges and heated through.
- Stir and Top with Crispy Onion Garnish: Remove the casserole from heat. Give it a gentle stir to redistribute sauce and ensure even cooking. Sprinkle the reserved 1/3 cup fried onions over the top as garnish, adding a fresh crispy texture before serving.
Notes
- Use whole milk for best creamy texture, but 2% milk can be substituted.
- Thaw frozen green beans completely to avoid excess water in the casserole.
- For a crisper topping, add the fried onions just before serving rather than baking them.
- This casserole can be prepared in advance and baked prior to serving; add the topping onions after baking.
- Adjust seasoning with salt sparingly as the cream of mushroom soup and soy sauce contribute salty flavors.
