How to Make Hamburger and Potato Casserole Recipe

Step 1: Brown the Ground Beef

Start by heating a large sauté pan over medium-high heat. Add the ground beef and cook it thoroughly, breaking it apart with a spatula until fully browned. This step builds the rich, savory foundation for the casserole. Then, mix in Italian seasoning, garlic powder, onion powder, and season with salt and pepper. The aromatic spices layer in extra depth that will infuse the entire dish.

Step 2: Prepare the Creamy Sauce

Next, whisk together cream of mushroom soup, sour cream, half and half, and Worcestershire sauce in a large bowl. Add generous pinches of salt and pepper to taste until you get a smooth, velvety mixture. Stir in about one cup of shredded Colby Jack cheese — this cheese will melt into the sauce, providing gooey richness throughout the casserole.

Step 3: Combine Beef, Potatoes, and Sauce

Now it’s time to bring it all together. Add the frozen diced hashbrowns and creamy soup mixture to the browned beef in the pan. Gently fold everything until the potatoes are thoroughly coated in the cheesy sauce. This combination ensures each bite offers a wonderful balance of tender potatoes, savory meat, and creamy goodness.

Step 4: Bake to Perfection

Transfer the mixture to a casserole dish, then sprinkle the remaining shredded cheese evenly over the top. Cover the dish tightly with foil to keep the moisture in and bake at 375 degrees for 45 to 55 minutes. You’ll know it’s ready when the potatoes are tender and the casserole is piping hot throughout.

Step 5: Broil for a Golden Finish

Once baking is done, remove the foil and pop the casserole under the broiler for 1 to 2 minutes. Watch carefully as the cheese melts and bubbles, turning a beautiful dark golden brown. This adds a crispy, irresistible top layer that contrasts perfectly with the creamy interior.

Step 6: Garnish and Serve

After removing from the oven, let the casserole rest for about 5 minutes. Sprinkle fresh sliced green onions and chopped parsley on top for a burst of color and mild freshness. Your Hamburger and Potato Casserole Recipe is now ready to be enjoyed!

Garnishes

Bright garnishes like green onions and parsley are wonderful because they add freshness and just a hint of sharpness to balance the rich casserole. Feel free to experiment with finely diced red bell pepper or a light dusting of smoked paprika for a pop of color and subtle smoky notes.

Side Dishes

This casserole is hearty enough to be a meal on its own, but serving it alongside a crisp green salad or steamed vegetables can add refreshing contrast. Lightly steamed broccoli or roasted asparagus pairs beautifully and keeps the meal balanced and vibrant.

Creative Ways to Present

For a fun twist, try serving this casserole in individual ramekins for personal portions at dinner parties. Alternatively, you can spoon it over a bed of fresh baby spinach or serve with a dollop of sour cream and a sprinkle of cheddar cheese for extra indulgence. The possibilities make this Hamburger and Potato Casserole Recipe perfect for casual family dinners or special occasions.

Make Ahead and Storage

Storing Leftovers

Leftover casserole should be transferred into an airtight container and stored in the refrigerator. It stays delicious for up to four days, making it perfect for quick reheats during busy weeks. The flavors even deepen after a day or two, so leftovers can be just as satisfying as the first serving.

Freezing

This Hamburger and Potato Casserole Recipe freezes well if you want to prep in advance. Place the cooled casserole in a freezer-safe container or cover tightly with foil and plastic wrap. It keeps for up to three months. Thaw overnight in the refrigerator before reheating for best texture and taste.

Reheating

Reheat the casserole in the oven at 350 degrees covered with foil until warmed through, about 20-25 minutes depending on portion size. Alternatively, microwave single servings on medium heat in short intervals, stirring occasionally to distribute heat evenly and keep that creamy texture intact.

FAQs

Can I use fresh potatoes instead of frozen hashbrowns?

Absolutely! Just be sure to peel and dice fresh potatoes into small, uniform cubes. Parboil them briefly to ensure they cook through evenly during baking, as fresh potatoes take longer to become tender compared to frozen hashbrowns.

Is there a way to make this casserole vegetarian?

Yes! You can substitute the ground beef with plant-based meat alternatives or sautéed mushrooms and lentils. Use vegetable broth and a mushroom-based soup to maintain the rich umami flavors while keeping it veggie-friendly.

Can I prepare this casserole a day ahead?

Definitely. You can assemble the casserole the day before, cover it tightly, and refrigerate it overnight. When ready to serve, just add a few extra minutes to the baking time since the casserole will be cold from the fridge.

What cheese works best for this casserole?

Colby Jack is ideal because it melts smoothly and has a mild flavor. However, cheddar, Monterey Jack, or a combination can also work wonderfully. Pick cheeses that melt well and complement the savory flavors.

How can I make this casserole spicier?

To add a spicy kick, stir in some crushed red pepper flakes or diced jalapeños to the beef while cooking. You can also sprinkle cayenne pepper into the sauce mixture for extra heat that balances with the creamy elements.
