Ingredients
Scale
Casserole Mixture
- 2 (10.5-ounce) cans cream of mushroom soup
- ⅓ cup whole milk
- ½ teaspoon salt
- ½ teaspoon black pepper
- 3 (14.5-ounce) cans cut green beans, drained
- ½ cup French fried onions (from one 6-ounce can)
Topping
- Remaining ½ cup French fried onions (from one 6-ounce can)
Others
- Nonstick cooking spray
Instructions
- Mix the Soup Base: In a medium mixing bowl, combine the cream of mushroom soup, whole milk, salt, and black pepper. Stir well until the mixture is smooth and evenly blended.
- Fold in Green Beans and Onions: Add the drained green beans to the soup mixture and gently fold them together. Stir in half of the French fried onions (about ½ cup) to incorporate some crunch into the casserole base.
- Prepare the Slow Cooker: Spray the inside of the slow cooker with nonstick cooking spray to prevent sticking. Spread the green bean mixture evenly across the bottom of the slow cooker.
- Cook the Casserole: Place the lid on the slow cooker and cook on low heat for 2 to 3 hours or on high heat for about 1 hour. The casserole is done when the green beans are tender and the sauce is bubbly and well combined.
- Add the Topping: Remove the slow cooker lid carefully. Sprinkle the remaining French fried onions evenly over the top of the casserole to add a crispy, golden finish.
- Serve: Serve the casserole hot or warm as a savory side dish alongside your main course.
Notes
- Drain the cans of green beans really well to avoid a watery casserole.
- If you prefer a thicker casserole, you can add a little more cream of mushroom soup or cook uncovered for the last 15 minutes to reduce liquid.
- For a lighter version, substitute whole milk with skim milk or a milk alternative.
- This dish can be kept warm in the slow cooker on the ‘warm’ setting for up to 1 hour after cooking.
- French fried onions added before cooking will soften, so the majority should be reserved for topping just before serving to maintain crunch.
