Scalloped Potatoes and Beef

This casserole goes over well with my family. It's best prepared well ahead of time so you have plenty of time for the long bake it requires.

Scalloped Potatoes and Beef
1 1/2 pounds ground beef
1 small onion
a small green pepper
2 Tbsp freshly chopped garlic
1/2 tsp red pepper flakes
1 tsp salt OR seasoned salt
1 tsp pepper

6-8 large baking potatoes, peeled and sliced thinly

Cook beef with onion, garlic, green pepper, salt, pepper and chili flakes. Cook until meat is browned. Drain if needed.

Sauce
1 recipe Cream of...soup, quadrupled (4x)
1/2 cup milk
1 cup sour cream or plain yogurt
1/2 cup grated Parmesan cheese
2 tsp garlic powder
2 tsp seasoned salt
black pepper to taste
2-2 1/2 cups grated cheese

Combine all sauce ingredients except cheese and stir until well combined.

In two greased 9x13's, begin layering potatoes, then sauce then a bit of cheese. Repeat until pans are full. Do not top with cheese yet. Cover with foil. Bake at 350 for 1 hour, then uncover and bake 30 more minutes. Remove from oven and sprinkle with remaining cheese. Bake for 5 more minutes. Allow to set for 10 minutes before serving.
