Slow Cooker Green Bean Casserole

  • Prep Time: 10 minutes
  • Cook Time: 2 hours on high or 4 hours on low
  • Total Time: 55 minute
  • Yield: 6-8 servings 1x


A very simple version of your favorite green bean casserole made in the slow cooker. Making this casserole in your slow cooker can free up valuable oven space and also makes this dish very portable.


  • 3 (14.5 oz) cans green beans, drained
  • 1 (13.75 oz) can cream of mushroom soup
  • 1/4 cup half and half
  • 1 tsp soy sauce
  • 1/4 tsp pepper
  • 1 1/3 cup french fried onions (divided)


  1. In your slow cooker add the green beans, cream of mushroom soup, half and half, soy sauce and pepper. Use a spoon to toss the mixture together. Thoroughly coat the green beans with the soup. Toss in 2/3 cup of the fried onions.
  2. Cover the slow cooker and cook on high for 2 hours or on low for 4 hours.
  3. Remove the lid. Sprinkle the remaining onions on top. Turn the broiler of your oven on and stick the crock insert under the broiler for 2 minutes. Remove the crock from the oven and serve the casserole when ready. Keep on warm setting until ready to serve.


I used my 3-quart casserole crock made by the Crock-Pot brand.*

I used canned green beans and a can of cream of mushroom soup for this easy slow cooker green bean casserole recipe out of pure convenience. But you you can also make your own cream of mushroom soup and use frozen green beans too. If you end up using frozen green beans just add 30-60 minutes to the cooking time.
