This ground beef and potatoes casserole has become my go-to rescue meal on busy weeknights when I need something hearty that pleases everyone at the table. The combination of savory beef, tender potatoes, and melty cheese creates the ultimate comfort food experience that never disappoints.
I first made this casserole during a particularly chaotic week when I needed something substantial that would provide leftovers. My family devoured it so quickly that I now regularly double the recipe to ensure we have extras for lunch the next day.
Ingredients
- Ground beef: Provides the hearty protein base. Choose 85/15 lean to fat ratio for the best flavor without excess grease
- Potatoes: The star starch that creates that satisfying comfort food texture. Yukon golds hold their shape while remaining creamy
- Onion: Creates the aromatic foundation. Sweet varieties like Vidalia add subtle flavor
- Garlic: Essential for depth of flavor. Fresh cloves make a noticeable difference over pre minced
- Cheddar cheese: Forms that irresistible golden topping. Sharp varieties provide the most flavor impact
- Sour cream: Creates the creamy binding texture. Full fat versions yield the richest result
- Beef broth: Adds moisture and intensifies the meaty flavor. Use low sodium to control salt levels
- Olive oil: For sautéing with a hint of flavor. Extra virgin isn't necessary here
- Salt and pepper: The essential seasoning duo. Freshly ground black pepper makes a difference
- Dried thyme: Adds earthy notes that complement beef beautifully. Crush between your fingers before adding
- Paprika: Provides subtle color and smoky undertones. Hungarian varieties offer the best flavor
Step-by-Step Instructions
- Prep Work:
- Begin by preheating your oven to 375°F. This temperature creates the perfect environment for the potatoes to cook through while developing a golden cheesy top. While the oven heats, peel and dice your potatoes into uniformly sized cubes about half an inch across to ensure they cook evenly. Finely chop the onion and mince the garlic cloves, keeping them separate since they'll go into the pan at different times.
- Create the Flavor Base:
- Heat olive oil in a large skillet over medium heat until it shimmers but doesn't smoke. Add the chopped onion first, cooking for about 3 minutes until it begins to soften and turn translucent. Then add the minced garlic and cook for just 30 seconds until fragrant. Be watchful here as garlic burns quickly and becomes bitter.
- Brown the Beef:
- Add the ground beef to the skillet, breaking it apart with a wooden spoon. Season with salt, pepper, thyme, and paprika, distributing the spices evenly throughout the meat. Cook for 5 to 7 minutes, continuing to break up any large chunks until no pink remains. The meat should develop some caramelized edges for maximum flavor.
- Deglaze and Simmer:
- Pour the beef broth into the skillet, using a wooden spoon to scrape up any browned bits from the bottom of the pan. These contain concentrated flavor that enriches the final dish. Allow the mixture to simmer for 2 to 3 minutes, reducing the liquid slightly and allowing the flavors to meld together.
- Combine Components:
- Transfer the beef mixture to a large mixing bowl and add the diced raw potatoes. The residual heat from the beef will give the potatoes a head start on cooking. Fold in the sour cream and half the cheddar cheese until everything is evenly coated. This creamy mixture will become the binding agent that holds everything together.
- Assemble and Bake:
- Transfer the mixture to a 9×13 inch baking dish, spreading it in an even layer. Sprinkle the remaining cheese over the top in an even layer. Cover tightly with aluminum foil, which traps steam to help cook the potatoes. Bake covered for 30 minutes, then remove the foil and continue baking for 10 to 15 minutes until the cheese is bubbly and beginning to brown in spots.
- Rest and Serve:
- Allow the casserole to rest for 10 minutes before serving. This critical step lets the casserole set and allows the flavors to settle. The wait is worth it for the perfect texture and taste experience.

My absolute favorite part of this recipe is how the potatoes absorb all the savory flavors from the beef and seasonings. I discovered this recipe during a particularly cold winter when my kitchen became the heart of our home. Now whenever I make it, the rich aroma instantly brings my family to the table with eager anticipation.
Make It Your Own
This casserole welcomes customization based on your preferences and what you have available. For a more substantial vegetable presence, add 1 cup of frozen mixed vegetables or diced bell peppers when combining the ingredients. If you enjoy heat, incorporate diced jalapeños or a dash of hot sauce. The recipe is incredibly forgiving, making it perfect for using up odds and ends from your refrigerator drawer.
Storage and Reheating
Once cooled, this casserole keeps beautifully in the refrigerator for up to 4 days in an airtight container. The flavors actually improve overnight as they have time to meld together. For reheating, the microwave works for individual portions, but for the best texture, reheat covered in a 350°F oven for about 20 minutes until heated through. If freezing, portion into individual servings for easier thawing, and use within 3 months for optimal quality.

Perfect Pairings
This hearty casserole stands beautifully on its own, but pairs wonderfully with simple sides. A crisp green salad with vinaigrette provides welcome freshness against the rich casserole. Steamed green beans or broccoli add color and nutrition. For bread lovers, garlic bread or dinner rolls make excellent companions for soaking up any extra sauce. Consider serving with a dollop of extra sour cream on top for added creaminess.
The History Behind the Dish
Beef and potato casseroles have long been a staple in American home cooking, especially in the Midwest where hearty, satisfying dishes are valued. This particular style of casserole gained popularity in the 1950s when convenient one dish meals became fashionable for busy households. The recipe has evolved over decades, with each family adapting it to their own tastes and available ingredients. This version combines the best traditional elements with modern flavor preferences.
