Easy Crock Pot Green Bean Casserole

A simple and warm side dish made mostly in the slow cooker using canned green beans, cream of mushroom soup, milk, and crispy fried onions.

  • Total Time: 255 minutes
  • Yield: 8 servings 1x

Ingredients

Scale
  • 4 (14.5-ounce) cans cut green beans, drained
  • 2 (10.5-ounce) cans condensed cream of mushroom soup
  • 1 cup whole milk
  • 1/2 cup sour cream
  • 1 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 2 tablespoons low-sodium soy sauce
  • 1 (6-ounce) can crispy fried onions, divided
  • Optional: 1 cup shredded cheddar cheese
  • Optional: 1/4 cup vegetable broth
  • Cooking spray or unsalted butter

Instructions

  1. Thoroughly drain green beans. In a large bowl, whisk together cream of mushroom soup, milk, sour cream, black pepper, garlic powder, onion powder, and soy sauce until smooth. Set aside 1 to 1.5 cups of crispy fried onions for topping.
  2. Lightly grease a 6-quart or larger slow cooker. Layer half of the drained green beans, half of the creamy soup mixture, half of the reserved crispy fried onions (approx. 1/2-3/4 cup), and half of the optional shredded cheese in the slow cooker. Repeat layering with the remaining green beans, soup mixture, crispy fried onions, and optional cheese.
  3. Cover and cook on LOW for 3-4 hours, or on HIGH for 1.5-2 hours, until hot, bubbly, and the sauce is thick and creamy. If too thick, stir in 1/4 cup vegetable broth and cook for an additional 15-20 minutes.
  4. Evenly sprinkle the remaining 1 to 1.5 cups of crispy fried onions over the hot casserole. If your slow cooker insert is oven-safe, transfer it to a preheated 375°F (190°C) oven and bake for 10-15 minutes until onions are golden brown and perfectly crispy. (Alternatively, if insert is not oven-safe, carefully scoop casserole into an oven-safe dish before baking.)
  5. Alternatively, after sprinkling the remaining crispy fried onions, replace the slow cooker lid and cook on HIGH for 15-30 minutes until onions are heated through and softened slightly (they will not be as crispy as the oven method).
  6. Turn off the slow cooker or remove from the oven. Let the casserole rest for 10-15 minutes before serving. Enjoy your delicious homemade Easy Crock Pot Green Bean Casserole!
