Ingredients
  

Main Ingredients
  • 1.5 lbs ground beef (or ground turkey)
  • 1 medium onion (chopped)
  • 3 cloves garlic (minced)
  • 5–6 medium russet potatoes (thinly sliced, about 1/8 inch)
  • 2 cups shredded cheddar cheese (divided)
  • 1 cup shredded mozzarella (optional, for extra meltiness)
  • 1 can cream of mushroom soup (or cream of chicken, 10.5 oz)
  • 1 cup milk
  • 1 tsp salt
  • 0.5 tsp black pepper
  • 0.5 tsp paprika (optional)
  • 1 tbsp olive oil or butter (for greasing the dish)

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with olive oil or butter.
  2. In a skillet, brown ground beef with chopped onion until fully cooked. Drain the excess fat.
  3. Stir in minced garlic, salt, pepper, and paprika.
  4. In a bowl, whisk together the cream of mushroom soup and milk until smooth.
Layering
  1. Layer half the sliced potatoes on the bottom of the baking dish.
  2. Spread half the beef mixture over the potatoes.
  3. Pour half the sauce over the beef and sprinkle with 1 cup of cheddar cheese.
  4. Repeat the layers with the remaining potatoes, beef, and sauce. Top with the remaining cheddar and mozzarella.
Baking
  1. Cover the dish with foil and bake for 45 minutes.
  2. Uncover and bake for an additional 15–20 minutes until potatoes are tender and cheese is bubbly and golden.
  3. Let rest for 5 minutes before serving.

Notes

For extra flavor, try adding some chopped bell peppers or mushrooms to the beef mixture. Use a mix of cheeses for different flavors; Monterey Jack or pepper jack works well. To save time, you can use pre-sliced potatoes from the store. You can assemble the casserole a day in advance, just ensure to add a few extra minutes to the baking time if it’s cold from the fridge.
