Mashed Potato Green Bean Casserole

Ingredients

  • 3 lb. mashed potato
    • 3 lb. Yukon gold potatoes
    • butter
    • milk or cream

    OR

    • 48 oz. store-bought mash
  • salt and pepper to taste
  • 4 cups green beans (fresh or frozen are perfect, canned are okay but won't be firm)
  • 1 can cream of mushroom soup (284 mL / 10.5 fl oz)
  • ⅓ cup milk
  • 1 tsp soy sauce
  • 1½ cup cheddar cheese, shredded
  • 6 oz. crispy onions (1 can if using French's)
  • butter or cooking spray (to grease pan)

Directions

  1. Preheat oven to 350°F.
  2. Lightly grease a baking dish (if making the full recipe, you'll want 9"x13") and set aside.
  3. Making your own mashed potatoes?
  4. If using fresh or frozen green beans, cook them first (steaming them over the boiling potatoes works nicely).
  5. Make the bean topping by mixing green beans, soup, milk, soy sauce, half the cheese, and half the onions.
  6. Add mashed potatoes to pan and smooth out to make an even layer. Pour green bean mix on top, then top with remaining cheese and crispy onions.
  7. Bake for 30 minutes.

Leftovers reheat nicely in the microwave, but throwing them back in the oven for 10 minutes is even better!
