Instructions Checklist
  • Preheat the oven to 375 degrees F (190 degrees C).

  • Mix 1/2 of the Cheddar cheese and 1/2 of the onions into the mashed potatoes. Spread potato mixture over the bottom and up the sides of a 2-quart casserole dish to form a shell.

  • Combine ham, frozen peas and carrots, mushroom soup, mustard, garlic, and pepper in a bowl; mix well. Spoon mixture into the mashed potato shell. Cover loosely with aluminum foil.

  • Bake in preheated oven for 45 minutes. Remove from oven and sprinkle remaining Cheddar cheese and onions over the top. Bake uncovered until cheese is melted, about 5 minutes. Remove and let rest for 5 to 10 minutes before serving.
