Preheat the oven to 350℉, and lightly spray a 2-quart casserole dish with cooking spray.
Heat a medium skillet over medium heat, and cook the ground beef until it's no longer pink. Drain the excess grease and return the beef to the pan.
1 pound ground beef
Add the onion powder, garlic powder, Italian seasoning, salt, and pepper. Stir to combine and continue cooking for an additional 2-3 minutes then remove from heat.
½ teaspoon onion powder, ½ teaspoon garlic powder, ½ teaspoon Italian seasoning, ½ teaspoon salt, ¼ teaspoon black pepper
Add the diced potatoes to the prepared casserole dish, and arrange in an even layer.
3 cups potatoes
In a medium mixing bowl, whisk together the cream of mushroom soup and milk and pour over the potatoes.
10 ½ ounces cream of mushroom soup, ¾ cup milk
Sprinkle the cooked ground beef over the potatoes and soup mixture. Cover tightly with aluminum foil, and bake for 55-65 minutes or until the potatoes are fork tender.
Remove from the oven and sprinkle the shredded cheese over the top. Return to the oven and bake, uncovered, for an additional 5-10 minutes or until the cheese melts.
