Cheesy Leftover Ham and Mashed Potato Casserole

Ingredients

  • 3 cups leftover mashed potatoes
  • 1 cup shredded Cheddar cheese, divided
  • 1 (2.8 ounce) package French fried onions, divided
  • 1.5 cups diced leftover cooked ham
  • 1 (10 ounce) package frozen peas and carrots, thawed and drained
  • 1 (10.75 ounce) can condensed cream of mushroom soup
  • 0.75 teaspoon dry mustard
  • 0.5 teaspoon granulated garlic
  • 0.25 teaspoon fresh ground black pepper
  • aluminum foil

Method

  1. Set your oven to heat to 375 degrees F (190 degrees C).
  2. Stir half of the shredded Cheddar cheese and half of the French fried onions into the leftover mashed potatoes. Press this potato blend to cover the base and sides of a 2-quart casserole dish, creating a shell.
  3. In a separate bowl, mix the diced ham, thawed peas and carrots, condensed cream of mushroom soup, dry mustard, granulated garlic, and fresh ground black pepper until well combined. Transfer this filling into the prepared potato shell. Loosely cover the dish with aluminum foil.
  4. Place the covered dish in the preheated oven and bake for 45 minutes. Take it out and scatter the remaining Cheddar cheese and French fried onions over the top. Return to the oven, uncovered, and bake until the cheese has melted, about 5 minutes. Allow the casserole to stand for 5 to 10 minutes before you serve it.
