• Condensed Soup: We used traditional Campbell's condensed cream of mushroom soup, but you can also use cream of chicken or cream of celery.
• Milk: We like whole milk for its rich, creamy texture, but you could use low-fat if that’s what you have on hand.
• Worcestershire Sauce: The addition of this savory, punchy sauce enhances its flavor. You can also substitute soy sauce.
• Spices: Dried onion and garlic, plus salt and black pepper to taste.
• French Fried Onions: The crispy onions really bring this dish to life.

Variations & Substitutions

• Green Bean:You can use 2 pounds of fresh or frozen green beans in your slow cooker green bean casserole. You’ll need to trim and halve the fresh green beans. If you want, blanch them briefly in boiling water for 2-3 minutes and then plunge them into ice water to retain their vibrant green color.
• Cheese: To add richness to the sauce, add 1 cup of shredded cheddar cheese or ½ cup Parmesan cheese.
• Condensed Soup: If you're not a fan of mushrooms, cream of chicken soup or cream of celery soup can be suitable alternatives.
• Bacon: Add cooked and crumbled crispy bacon for a smoky flavor.
• Sautéed Mushrooms:Boost the mushroom flavor by adding sautéed fresh mushrooms to the casserole sauce before cooking.

Step-By-Step Instructions

1.Prepare the Beans:Open and drain the green bean cans. Place them in the slow cooker.

2.Mix the Sauce: In a medium bowl, whisk together the cream of mushroom soup, milk, Worcestershire sauce, garlic powder, onion powder, half of the French-fried onions, salt, and pepper (Image 1). Pour the soup mixture over the green beans and gently stir to combine (Image 2).

PRO TIP: You can add shredded cheddar cheese or Parmesan to the sauce at this point if you want to add extra richness.

3.Cook: Cover with the lid and cook on LOW for about 4 hours or until bubbly and heated through.

4.Add Topping:Just before serving, sprinkle the remaining onions over the top of the casserole (Image 3). Serve warm.

PRO TIP:Optional—If you want an extra crispy top, transfer the slow cooker insert (if it’s oven-safe) to the oven and broil for a few minutes until the onions are golden brown.

Expert Tips

• Add Toppings at the End: To keep the crispy texture of the fried onions, add the remaining as a topping for the last 30 minutes of cooking. So good!

• Make-Ahead: Combine all the ingredients except the onion topping. When ready to cook, transfer the mixture to a crock pot and cook as instructed.
• Serving: You can leave the casserole in the slow cooker or transfer it to a casserole dish for your holiday meal.
