How to Make It

Follow these steps to create your hamburger potato casserole.

Preheat the oven

Preheat your oven to 375°F (190 °C) to prepare for baking.

Cook the beef

In a skillet over medium heat, place the ground beef and break it apart. Cook for 7 to 10 minutes, or until fully browned. Drain excess fat to maintain a lighter dish.

Sauté the onion

Return the skillet to medium heat and add the chopped onion. Sauté for 3 to 4 minutes until the onion is translucent and fragrant. Season with salt, pepper, and garlic powder, stirring for an additional minute.

Prepare the potatoes

While the beef mixture cooks, peel and slice the potatoes as thinly as possible. In a greased 9×13-inch baking dish, lay half of the potato slices in a single, even layer. Season with a touch of salt and pepper.

Layer the ingredients

Spread the beef-onion mixture evenly over the potato layer, then top with the remaining potato slices.

Mix the milk and butter

In a small bowl, whisk together the milk and melted butter. Pour this mixture carefully over the top, ensuring it seeps between the layers.

Add cheese

Sprinkle 1 to 2 cups of shredded cheese evenly over the casserole to ensure complete coverage.

Bake covered

Cover the baking dish with foil and place it in the preheated oven for 45 minutes to allow the potatoes to soften.

Bake uncovered

After 45 minutes, remove the foil and continue baking for another 15 to 20 minutes until the cheese is bubbly and golden brown. Check the doneness by poking a fork into the potatoes; they should be tender.

Rest and serve

Once baked, let the casserole rest for about 10 minutes before slicing and serving.

How to Store It

Fridge: 3 to 4 days in an airtight container.
Freezer: Yes, for up to 3 months.
Reheat: In the oven at 350°F for 20 minutes or until heated through.

Tips for Best Results

• Slice the potatoes as thinly as possible for even cooking.
• Use fresh spices for the best flavor and aroma.
• Allow the casserole to rest before slicing to keep layers intact.
• Experiment with different cheese blends for variety.

Serving Suggestions

• Serve with a side salad for a balanced meal.
