Ingredients You’ll Need
This recipe relies on everyday ingredients that deliver big flavor with minimal effort:
- 1 lb (450 g) ground beef
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 can (10.5 oz / 300 g) cream of mushroom soup
Swap with cream of celery or cream of chicken if preferred. - ½ cup sour cream
- 1 cup shredded cheddar cheese, plus extra for topping
- 4 cups peeled and diced potatoes (about 4 medium)
- 1 cup milk
- 2 tablespoons butter
- Salt and black pepper, to taste
- Optional garnish: chopped parsley or green onions
Step-by-Step Method
1. Preheat the Oven
Set your oven to 350°F (175°C) so the casserole cooks evenly and the cheese melts into a golden, bubbly topping.
2. Parboil the Potatoes
Dice potatoes into small, even cubes.
Boil in lightly salted water for 5–7 minutes until just slightly tender.
Drain and set aside.
This step ensures soft, perfectly cooked potatoes after baking.
3. Brown the Beef
In a skillet over medium heat, melt 1 tablespoon butter.
Sauté onion and garlic for 3–4 minutes until fragrant.
Add ground beef, breaking it apart, and cook until browned with no pink remaining.
Drain excess fat.
4. Mix the Creamy Base
In a large bowl, combine:
- Cream of mushroom soup
- Sour cream
- Milk
- 1 cup shredded cheddar
- Salt and pepper
Stir until smooth and creamy—this forms the rich sauce that binds the casserole together.
5. Layer the Casserole
Grease a 9×13-inch baking dish, then layer:
- Half the parboiled potatoes
- All the cooked beef mixture
- Half the creamy sauce
- Remaining potatoes
- Remaining sauce
Finish with a generous sprinkle of cheddar cheese on top.
6. Bake Until Golden
- Cover with foil and bake 30 minutes
- Remove foil and bake 15–20 minutes more, until
- Cheese is melted and bubbly
- Potatoes are fork-tender
7. Rest and Serve
Let the casserole sit 5 minutes before serving.
Garnish with parsley or green onions for color and freshness.
Serve hot with a simple salad or steamed vegetables for a complete meal.

The result is a simple, nostalgic, family-friendly dinner that’s easy to prepare and always satisfying.
