Slow Cooker Green Bean Casserole
Author: Sarah Olson
Prep time: 10 mins
Cook time: 2 hours 40 mins
Total time: 2 hours 50 mins
  • (3) 10¾ ounce cans Cream of Mushroom Soup
  • ½ Cup Milk
  • ⅛ teaspoon Black Pepper
  • ⅛ teaspoon Onion Powder
  • (10) 14.5 ounce Cans Del Monte Cut Green Beans (drained)
  • (2) 6 ounce canisters French's French Fried Onions (note- one is mixed in, one is the topping)
  • Non-Stick Cooking Oil Spray
  1. In a very large bowl, add the cream of mushrooms soup, milk, black pepper, and onion powder, whisk until smooth.
  2. Add the drained green beans, and 1 of the canisters of french fried onions into the large bowl with the soup mixture you just made, and with a spatula, fold everything together, being careful not to break the green beans up.
  3. Spray the slow cooker with the non-stick cooking spray, and add the green bean mixture to the slow cooker.
  4. Cook on HIGH for 2.5 hours.
  5. After cooking time is done, add the other canister of french fried onions onto the green beans. Take the slow cooker insert out of the heating element, and put into the oven (without the lid on!). My oven was set at 350 degrees. Cook for about 10 minutes, or until the onions are browned.
  6. Set the insert back into the slow cooker heating elelment, replace the lid, and set the slow cooker to WARM until ready to serve. Enjoy!
