Ingredients

Vegetables

  • 4 (14.5 oz) cans French Cut Green Beans, drained

Soups

  • 1 (10.5 oz) can Cream of Mushroom Soup
  • 1 (10.5 oz) can Cream of Celery Soup

Cheese and Toppings

  • 2 cups Sharp Cheddar Cheese, grated and divided (about one 8 oz block)
  • 1 (6 oz) container French Fried Onions, divided

Seasoning

  • ¼ teaspoon Kosher Salt

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for slow roasting the casserole.
  2. Mix Ingredients: In a large mixing bowl, gently combine the drained French cut green beans, cream of mushroom soup, cream of celery soup, half of the French fried onions, half of the grated sharp cheddar cheese, and ¼ teaspoon of kosher salt. Mix just until evenly combined to maintain some texture.
  3. Prepare Baking Dish: Grease a casserole dish lightly to prevent sticking and transfer the mixture into the dish, spreading it out evenly.
  4. Add Toppings: Sprinkle the remaining cheddar cheese evenly over the top of the green bean mixture, then add the rest of the French fried onions as the final topping to create a crispy crust.
  5. Bake: Place the casserole in the preheated oven and bake for 1 hour. At the 30-minute mark, carefully turn the casserole to ensure an evenly golden and crispy crust on all sides.
  6. Cool Before Serving: Once baked, remove the casserole from the oven and allow it to cool for 20 minutes before serving. This resting time helps the casserole set and enhances flavors.

Notes

  • Turning the casserole halfway through baking ensures an evenly crispy crust all around.
  • Slow roasting at 375°F creates a creamier texture compared to traditional baking methods.
  • You can substitute sharp cheddar with a different cheese if preferred, but cheddar adds a nice sharpness and melting quality.
  • This casserole pairs wonderfully with roasted meats and is a classic holiday side dish.
  • Letting it cool before serving helps the casserole hold its shape better when plated.
