Ground Beef Potatoes Casserole

This Ground Beef Potatoes Casserole is pure comfort food that reminds me of Sunday dinners at my grandmother’s house. This hearty casserole combines seasoned ground beef with tender potato cubes and plenty of sharp cheddar cheese for a meal that satisfies everyone at the table. I love how the sour cream makes everything creamy while the beef broth keeps the potatoes perfectly moist.

I first made this ground beef and potato casserole on a chilly October evening when I needed something warming and filling. The smell of thyme and paprika mixing with browning beef and onions immediately transported me back to my childhood. This Ground Beef Potatoes Casserole has become my go-to dish for feeding a crowd because it’s affordable, simple to make, and universally loved. Even my pickiest eater devours this without complaint, and the leftovers taste even better the next day.

Simple Ingredients for Hearty Comfort

I always use Yukon Gold potatoes for this Ground Beef Potatoes Casserole because they hold their shape beautifully during baking and have a naturally buttery flavor. Pro tip: dice your potatoes into uniform half-inch cubes so they cook evenly.

• 1 pound ground beef (80-85% lean)
• 4 medium russet or Yukon Gold potatoes, peeled and diced into 1/2-inch cubes
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 1 cup shredded cheddar cheese, sharp cheddar preferred
• 1 cup sour cream, full fat for best texture
• 1/2 cup beef broth, low sodium
• 1 tablespoon olive oil, extra virgin preferred
• 1 teaspoon salt, fine sea salt
• 1/2 teaspoon black pepper, freshly ground
• 1 teaspoon dried thyme
• 1/2 teaspoon paprika

Personal tip: I prefer sharp cheddar cheese in this Ground Beef Potatoes Casserole because it has more flavor than mild cheddar. Full-fat sour cream makes the dish creamier and richer, but you can use low-fat if you’re watching calories. Fresh garlic is always better than garlic powder for this recipe.

Building Your Beef and Potato Casserole

Step 1: Preheat your oven to 375°F so it’s ready when you need it. Take your peeled potatoes and dice them into small, uniform cubes about half an inch wide. Try to keep them all the same size so they cook at the same rate. Set the diced potatoes aside in a bowl.

Step 2: Finely chop the onion and mince the garlic cloves. The smaller you chop the onion, the better it will distribute throughout the Ground Beef Potatoes Casserole. I like my onion pieces pretty small, about the size of a pea.

Step 3: Heat the tablespoon of olive oil in a large skillet over medium heat. When the oil shimmers, add the chopped onion and minced garlic. Cook slowly for 4-5 minutes, stirring often so they don’t burn. The onions should become soft and fragrant, turning translucent with golden edges. The garlic should smell amazing but shouldn’t brown or it will taste bitter.

Step 4: Add the ground beef to the skillet with the onions and garlic. Break it up with a wooden spoon as it cooks, crumbling it into small pieces. Sprinkle in the salt, black pepper, dried thyme, and paprika. Keep stirring and breaking up the meat as it cooks. You want small, even crumbles, not big chunks. Cook for 7-8 minutes until the meat is fully browned and no pink remains anywhere. The beef should be nicely caramelized in spots.

Step 5: Pour in the beef broth and stir thoroughly, scraping up any browned bits stuck to the bottom of the pan. Those bits are pure flavor. Let the mixture simmer for about 4 minutes so the flavors can meld together and the liquid reduces slightly. The broth should almost completely absorb into the beef, leaving it moist but not soupy.

Step 6: Remove the skillet from the heat. In a large mixing bowl, gently combine the cooked beef mixture with the diced raw potatoes. Add the sour cream and half of the shredded cheddar cheese (about 1/2 cup). Fold everything together well, making sure the potatoes are evenly coated with the creamy mixture. Every potato cube should have some beef and sauce clinging to it.

Step 7: Spoon the entire mixture into a lightly greased 9×13 inch baking dish. Use a spatula to spread it out into an even layer, pressing down gently so there are no air pockets. Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top, making sure to cover all the way to the edges.

Step 8: Cover the baking dish tightly with aluminum foil. This is important because it traps steam and helps the potatoes cook through. Bake covered for 30 minutes. The potatoes will become soft and the flavors will blend beautifully.

Step 9: After 30 minutes, carefully remove the foil (watch out for hot steam). Return the uncovered Ground Beef Potatoes Casserole to the oven and bake for another 10-15 minutes. You’re looking for the cheese topping to be bubbling, melted, and turning golden brown in spots. The edges should be slightly crispy.

Step 10: Let the casserole rest for 10 minutes before serving. This resting time is crucial because it allows the sauce to thicken slightly and makes the casserole easier to serve. If you cut into it right away, everything will be too loose and runny. Serve hot, either on its own or with a simple green salad.

Pro tip: Test the potatoes with a fork before removing the foil. They should be tender all the way through. If they still feel firm, cover again and bake 10 minutes more.

Perfect Sides for Ground Beef Casserole

This Ground Beef Potatoes Casserole is filling on its own, but these sides add freshness and balance to the rich, hearty flavors.

Crisp green salad: A simple salad with mixed greens, cucumbers, and tomatoes dressed with vinaigrette cuts through the richness. The cool, crunchy vegetables balance the warm, creamy casserole perfectly.

Roasted green vegetables: Brussels sprouts, broccoli, or green beans roasted until slightly charred add nutrition and a slight bitterness that complements the savory beef and potatoes beautifully.

Sliced pickled jalapeños: For those who like heat, pickled jalapeños on the side add tangy spice. They’re especially good spooned right on top of each serving of the Ground Beef Potatoes Casserole.

Extra sour cream: A dollop of cold sour cream on top of your hot serving makes it even more luscious. The temperature contrast is wonderful and adds extra creaminess.

Dinner rolls: While not necessary, warm, buttery rolls are perfect for soaking up any sauce left on your plate. They turn this into an even more substantial meal.

Storing Your Potato Casserole

Your Ground Beef Potatoes Casserole will stay fresh in an airtight container in the refrigerator for up to 4 days. The flavors continue to develop as it sits, making leftovers incredibly delicious. Make sure to let it cool completely before covering and storing to prevent condensation.

When you’re ready to reheat, you can warm individual portions in the microwave in 90-second intervals, stirring between each, until hot throughout. For larger portions, reheat gently in the oven at 325°F covered with foil for about 20 minutes. Add a splash of beef broth or water if it seems dry.

Pro tip: This casserole freezes beautifully for up to 3 months. I recommend wrapping it tightly in plastic wrap, then covering with aluminum foil for extra protection against freezer burn. You can freeze the whole casserole or portion it into individual servings for easier reheating. Thaw overnight in the refrigerator before reheating. The texture of the potatoes might change slightly after freezing, but the flavor remains delicious.
