A stress-free, creamy green bean casserole made in a slow cooker. This easy holiday side dish uses simple pantry ingredients to create a rich, savory dish that stays warm and delicious without taking up oven space.

Ingredients

Scale
  • 1 bag frozen cut green beans (thawed and drained)
  • 1 can condensed mushroom soup (high quality, not light)
  • 1/2 cup heavy cream or half-and-half
  • 1 cup sharp cheddar cheese, freshly grated
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon black pepper
  • 1 can fried onions (for topping)
  • 1 tablespoon butter (optional, for greasing or sautéing)

Instructions

  1. Prep the beans: If using frozen, thaw slightly and squeeze out excess liquid to prevent a watery casserole. Place beans in the slow cooker insert.
  2. Mix the base: In a large bowl, whisk together the condensed mushroom soup, heavy cream, garlic powder, onion powder, and black pepper until smooth.
  3. Combine: Pour the sauce over the green beans and stir well to coat evenly.
  4. Cook: Cover and cook on LOW for 3 to 4 hours. Do not cook on HIGH to avoid mushy beans and separated sauce.
  5. Add cheese: About 30 minutes before serving, stir in the shredded cheddar cheese. Cover and let sit on LOW for another 20-30 minutes until melted.
  6. Top and serve: Just before serving, top with fried onions. Stir slightly to distribute but leave some on top for crunch. Serve immediately.

Notes

Ensure frozen beans are thoroughly drained and squeezed to avoid a soupy texture. Use freshly grated cheese rather than pre-shredded to ensure smooth melting. Taste the sauce before cooking as condensed soup is very salty. For a gluten-free version, verify that the soup and fried onions are certified gluten-free.
