How to Make Green Bean Casserole in the Slow Cooker – Step by Step
Step 1: Prepare the Green Beans
Wash and trim the ends off your green beans. Cut them in half and place them evenly at the bottom of your slow cooker. Using fresh green beans ensures a tender-crisp texture after slow cooking.
Step 2: Mix the Creamy Sauce
In a mixing bowl, combine the cream of mushroom soup, milk, sour cream, and chopped onion. Stir until smooth and well blended. This rich mixture forms the savory base of your casserole.
Step 3: Assemble the Casserole
Pour the creamy mushroom sauce over the green beans in the crockpot. Then layer the crumbled bacon and shredded cheddar cheese on top. Sprinkle in garlic powder, salt, and pepper for added flavor.
Step 4: Slow Cook to Perfection
Cover and cook on LOW for 4 to 5 hours or until the green beans are fork-tender and the flavors are fully combined.
Step 5: Add the Crispy Onion Topping
About 30 minutes before serving, open the lid and sprinkle the French fried onions evenly over the top of the casserole. Close the lid again and let them warm up, becoming slightly crispy while soaking up some of the savory steam.
Step 6: Serve and Enjoy
Serve this hot and cheesy green bean casserole as a side dish for Thanksgiving, Christmas, or any comforting dinner.
