Ingredients

  • 2 cans green beans, drained
  • 1 can cream of mushroom soup
  • 1 cup milk
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 cup shredded cheddar cheese
  • 1 cup French fried onions
  • Salt and pepper to taste

Instructions

  1. Step 1: Combine the green beans, cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper in the slow cooker. Stir until well mixed.
  2. Step 2: Cover and cook on low for 4 hours, allowing the flavors to meld and the mixture to heat through.
  3. Step 3: Stir in the shredded cheddar cheese and half of the French fried onions, then cook uncovered for an additional 30 minutes.
  4. Step 4: Before serving, top the casserole with the remaining fried onions and let it sit for a few minutes to allow the topping to crisp up.

Tips & Variations

  • For a creamier texture, add a splash of heavy cream instead of milk.
  • Try using fresh green beans blanched briefly if you prefer less canned ingredients.
  • Add a sprinkle of paprika or cayenne pepper for a subtle smoky kick.
  • To make it vegetarian-friendly, ensure the cream of mushroom soup and fried onions use no animal products.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven at 350°F (175°C) until heated through, or microwave individual portions until hot. The fried onion topping may lose some crispness—add fresh fried onions after reheating for best texture.
