This cozy slow cooker green bean casserole delivers creamy, savory flavor with almost no effort. Toss it together, let it bubble, then finish with a crunchy onion topping.
Grease the slow cooker lightly or mist with cooking spray.
Whisk the condensed soup, milk, soy sauce, garlic powder, onion powder, salt, and pepper in a large bowl.
Fold in the green beans, cheddar, and 1 cup fried onions until evenly coated.
Spread the mixture into the slow cooker and smooth the top.
Cover and cook on Low for about 2 hours 20 minutes, until hot and bubbling at the edges.
Scatter the remaining fried onions on top. Cover and cook 10 minutes more to warm the topping.
Notes
Make it your own: Swap cheddar for Swiss or pepper jack, or stir in sautéed mushrooms or crisp bacon before cooking. For an extra-crispy finish, broil the topping separately on a sheet pan for 2–3 minutes, then add just before serving. Leftovers keep 3–4 days refrigerated; reheat covered at 325°F until warmed through.This recipe is an original creation inspired by classic Easy Crock Pot Green Bean Casserole flavors.
