Ingredients
  

Ingredients
  • 4 cups fresh green beans, trimmed and cut into 2-inch pieces (or use two 14.5 oz cans, drained)
  • 1 medium onion, finely chopped
  • 1 cup sliced mushrooms (optional, but traditional in Amish recipes)
  • 2 cans (10.5 oz each) Halal cream of mushroom soup
  • 1 cup Halal sour cream
  • 1 cup shredded Halal cheddar cheese or Colby Jack (divided, half included in sauce and half for topping)
  • 1 cup crispy fried onions (divided, half stirred into the mixture and half for topping)
  • 1/2 cup Halal milk
  • 1 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt (adjust if using canned beans)

Equipment

  • Slow cooker
  • Large mixing bowl
  • Whisk

Method
 

  1. Prepare your slow cooker by coating the inside with nonstick spray or butter.
  2. In a large mixing bowl, whisk together the 2 cans of Halal cream of mushroom soup, 1 cup of Halal sour cream, and 1/2 cup of Halal milk until smooth.
  3. Stir in the garlic powder, salt, and black pepper.
  4. Add the chopped onion, sliced mushrooms (if using), half of the shredded cheese, and half of the crispy fried onions to the mixture and stir until combined.
  5. Place the fresh green beans (or drained canned beans) into the prepared slow cooker and pour the creamy mixture over them, stirring gently to coat evenly.
  6. Cover the slow cooker and set it to low heat for 4 to 6 hours.
  7. During the last 15-20 minutes of cooking, sprinkle the remaining cheese and crispy fried onions on top, then continue cooking uncovered until the topping turns golden and slightly crunchy.

Notes

This slow cooker casserole is ideal for those busy days when you want a delicious, comforting meal with minimal effort. You can easily substitute the mushrooms with cream of celery or chicken soup for a different twist, and if fresh green beans aren’t available, canned or thawed frozen beans work just as well. The dish comes together with a rich sauce that melds into the beans during slow cooking, and the crispy fried onions added at the end give it a satisfying crunch. Store any leftovers in an airtight container and reheat gently for another comforting meal.
