🥩 Ingredients for the Perfect Cheesy Hamburger Potato Casserole

To create the most flavorful and satisfying casserole, start with high-quality ingredients that balance taste and texture.

1 lb (450g) ground beef – Use 80/20 lean beef for the best flavor.
1 medium onion, finely chopped
2 cloves of garlic, minced
4 medium potatoes, thinly sliced (Yukon Gold or Russet are ideal for structure and taste)
1 can (10.5 oz / 295g) cream of mushroom soup
½ cup sour cream
½ cup milk (whole milk preferred for creaminess)
2 cups shredded cheddar cheese, divided
1 teaspoon paprika
Salt and freshly ground black pepper, to taste
Butter or cooking spray, for greasing the baking dish
Optional garnishes: freshly chopped parsley, green onions, or crumbled bacon

🔥 Step-by-Step Instructions to Prepare This Casserole Masterpiece

1. Prepare the Baking Dish and Preheat Oven

Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) casserole dish with butter or non-stick spray to prevent sticking and ensure easy cleanup.

2. Brown the Ground Beef and Aromatics

In a large skillet over medium heat, add the ground beef and chopped onion. Sauté for 7–9 minutes, or until the beef is fully browned and the onions are translucent. Stir in minced garlic, paprika, salt, and pepper. Cook for an additional minute to bloom the spices. Drain any excess fat to prevent a greasy casserole.

3. Prepare the Creamy Sauce

In a medium mixing bowl, combine:

Cream of mushroom soup
Sour cream
Milk
1 cup of shredded cheddar cheese

Whisk until the mixture is smooth and well-blended. This sauce is what binds the entire casserole together, adding moisture and creamy texture.

4. Slice the Potatoes Thinly

Using a mandoline or sharp knife, slice the potatoes into ⅛-inch (3mm) rounds. The thinner the slices, the faster and more evenly they cook.

🥘 Assembling the Cheesy Hamburger Potato Casserole

Layering is key to achieving even cooking and a well-balanced bite in every forkful.

First layer: Arrange half of the sliced potatoes on the bottom of the greased baking dish.
Second layer: Spread half of the ground beef mixture evenly over the potatoes.
Third layer: Pour half of the creamy cheese sauce over the beef.
Add a sprinkle of shredded cheese for extra richness.

Repeat the layers with the remaining potatoes, beef, and sauce. Finish by topping the entire casserole with the remaining 1 cup of shredded cheddar cheese, covering the top completely for that golden, melty crust.

⏲️ Baking Instructions for Perfect Texture

Cover the dish tightly with aluminum foil and bake in the preheated oven for 60 minutes.
After an hour, remove the foil and bake uncovered for an additional 20–25 minutes, or until the potatoes are fork-tender and the cheese on top is bubbly and golden brown.

🛑 Let It Rest Before Serving

Once baked, remove the casserole from the oven and let it rest for 10 minutes. This allows the layers to settle and makes serving cleaner and easier.

🍴 Serving Suggestions for a Balanced Meal

This casserole is a rich, satisfying dish on its own but pairs beautifully with:

Steamed vegetables like green beans, broccoli, or carrots
A crisp green salad with vinaigrette to cut through the richness
Garlic bread or dinner rolls to scoop up any cheesy, saucy goodness
