Instructions
Layer the Green Beans – Place the trimmed and halved green beans in the bottom of your slow cooker.
Mix the Sauce – In a mixing bowl, combine the cream of mushroom soup, milk, sour cream, and chopped onion. Stir until well blended.
Assemble the Casserole – Pour the soup mixture over the green beans. Top with crumbled bacon and shredded cheddar cheese. Sprinkle with garlic powder, salt, and pepper.
Cook – Cover and cook on LOW for 4–5 hours, or until the green beans are tender.
Finish with the Topping – About 30 minutes before serving, sprinkle French fried onions over the top. Cover again to warm them through and keep them crispy.

Tips
- For a deeper flavor, sauté the onion in a bit of butter before adding it to the sauce.
- Swap cheddar for Gruyère or Colby Jack for a fun flavor twist.
- If you prefer softer beans, extend the cooking time by 30–45 minutes.
Storage
Refrigerate leftovers in an airtight container for up to 3 days. Reheat in the oven or air fryer to keep the onion topping crispy.
