Ingredients

Scale

Green Bean Mixture

  • 2 (14.5 ounce) cans green beans, drained
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1/2 cup shredded Cheddar cheese

Topping

  • 1/2 cup shredded Cheddar cheese
  • 1 (6 ounce) can French-fried onions

Instructions

  1. Preheat Oven: Preheat the oven to 350 degrees F (175 degrees C) to get it ready for baking the casserole.
  2. Mix Green Beans and Soup: In a large microwave-safe bowl, combine the drained green beans and condensed cream of mushroom soup. Stir well to blend the flavors evenly.
  3. Warm the Mixture: Microwave the green bean and soup mixture on high for 3 to 5 minutes until warmed through, which helps meld the flavors.
  4. Add Cheese: Stir 1/2 cup of shredded Cheddar cheese into the warm mixture. Microwave again on high for 2 to 3 minutes to melt the cheese and make the casserole creamy.
  5. Assemble in Casserole Dish: Transfer the cheesy green bean mixture into a casserole dish, spreading it evenly across the bottom for uniform baking.
  6. Add Toppings: Sprinkle the remaining 1/2 cup of shredded Cheddar cheese evenly over the top, then spread the French-fried onions on top for a crispy, golden topping.
  7. Bake: Place the casserole in the preheated oven and bake for about 10 minutes, or until the cheese is melted and the French-fried onions are just turning golden brown and crispy.

Notes

  • For best results when reheating, allow the casserole to come to room temperature for about 30 minutes before baking again.
  • When reheating, add fresh French-fried onions on top for extra crunch.
  • You can substitute fresh green beans if preferred; blanch them first before mixing.
  • Use reduced-fat Cheddar cheese for a lighter version, but it may affect creaminess.
  • This recipe can easily be doubled to feed a larger crowd.
