Ground Beef and Potatoes Casserole is a hearty, comforting dish that brings together simple, familiar ingredients like seasoned ground beef, tender potatoes, and melted cheese. It’s one of those classic casseroles where the flavors blend perfectly, making a warm and filling meal that feels like a big, cozy hug.
I love making this casserole on a busy weeknight because it’s easy to put together, and it fills up the whole kitchen with a delicious, homey smell that everyone loves. One little trick I like is to add a sprinkle of herbs or a bit of onion and garlic for extra flavor, but you can keep it basic too, and it’s still great. Plus, leftovers heat up wonderfully, which is a big win in my book.
We usually serve this casserole with a simple side salad or some steamed veggies to add a little green to the plate. It’s a great meal for feeding the family or even taking along to a potluck because it’s always a hit. Whenever I make it, I remember how my family gathered around the table, enjoying each bite, and that’s what makes this dish special to me.
Key Ingredients & Substitutions
Ground beef: It’s the heart of this dish, giving rich flavor and protein. I like to use lean ground beef to keep it from getting too greasy, but ground turkey or chicken works well if you want a lighter option.
Potatoes: Thin slices help them cook evenly and soak up juices. Yukon gold or red potatoes are great for their creamy texture. Russets work too, but may absorb more liquid.
Cheddar cheese: Sharp cheddar brings a nice tang and melts beautifully. If you prefer milder cheese, mozzarella or Monterey Jack are good substitutes.
Tomatoes and tomato paste: They add moisture and a touch of acidity to balance the beef. If canned tomatoes aren’t available, fresh diced tomatoes or tomato sauce can be used instead.
How Do You Get the Potatoes Perfectly Tender and Layered?
The trick is slicing the potatoes thin and layering carefully. Thin slices cook faster and soften well in the oven. Here’s how to do it right:
- Use a sharp knife or mandoline to slice potatoes about 1/8-inch thick for even cooking.
- Arrange the slices in an even layer to avoid clumping and ensure heat spreads evenly.
- Lightly season each potato layer to boost flavor throughout the casserole.
- Cover with foil during baking to trap steam, helping the potatoes soften without drying out.
Letting the casserole rest after baking helps the layers set and makes serving easier. This simple attention to layering and baking creates tender, tasty potatoes every time.

Equipment You’ll Need
- Large skillet – perfect for browning the ground beef and sautéing onions evenly.
- Sharp knife or mandoline – makes slicing potatoes thin and uniform quick and easy.
- 9×13 inch casserole dish – roomy enough for layering potatoes and beef without crowding.
- Aluminum foil – keeps moisture in while baking so potatoes cook tender.
- Spatula or large spoon – for spreading and layering ingredients smoothly in the dish.
Flavor Variations & Add-Ins
- Swap ground beef with ground turkey or chicken for a lighter, leaner casserole.
- Add sliced mushrooms or bell peppers to the beef mixture for extra veggies and flavor.
- Use a mix of cheeses like mozzarella and cheddar to create a milder, gooey topping.
- Stir in fresh or dried herbs like thyme or rosemary to give the dish a fragrant, earthy touch.
How to Make Ground Beef and Potatoes Casserole
Ingredients You’ll Need:
For the Beef Mixture:
- 1 1/2 pounds ground beef
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes, drained
- 1 tablespoon tomato paste (optional)
- 1 teaspoon dried oregano
- 1 teaspoon paprika
- Salt and pepper, to taste
- 2 tablespoons olive oil or butter
For the Casserole Layers:
- 4 large potatoes, peeled and thinly sliced
- 2 cups shredded sharp cheddar cheese
- 1/4 cup chopped green onions or fresh parsley for garnish
How Much Time Will You Need?
This casserole takes about 20 minutes to prepare and 1 hour to bake. After baking, allow 5-10 minutes to rest before serving to let it set up nicely.
Step-by-Step Instructions:
1. Preparing the Beef Mixture:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until it becomes translucent, about 4 to 5 minutes. Add the minced garlic and cook for another 30 seconds until fragrant.
Next, add the ground beef to the skillet. Cook it thoroughly, breaking it apart with your spoon, until browned. Drain any excess fat. Then stir in diced tomatoes, tomato paste if using, oregano, paprika, and salt and pepper. Let it simmer gently for 5 minutes so the flavors blend. Remove from heat.
2. Layering the Casserole:
Arrange half of the thinly sliced potatoes in an even layer on the bottom of your greased casserole dish. Lightly sprinkle with salt and pepper. Spread half of the beef mixture evenly over the potatoes, then sprinkle 1 cup of shredded cheddar cheese on top.
Repeat with the remaining potatoes and beef, topping it finally with the last cup of cheese. Cover the dish tightly with aluminum foil.
3. Baking and Serving:
Bake the covered casserole for 45 minutes. Then, remove the foil and bake for another 15 to 20 minutes, or until the potatoes are tender when pierced with a fork and the cheese is melted and bubbly.
Take the casserole out of the oven and let it rest for 5 to 10 minutes. Sprinkle with chopped green onions or parsley for a fresh, colorful touch before serving.
Can I Use Frozen Ground Beef for This Casserole?
Yes, you can use frozen ground beef, but be sure to thaw it completely before cooking. Thaw it overnight in the fridge or use the defrost setting on your microwave for quicker thawing. This ensures even cooking and better texture.
Can I Prepare This Casserole Ahead of Time?
Absolutely! Assemble the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. When ready, bake as instructed, adding a few extra minutes if baking straight from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through to keep the potatoes tender and the cheese melty.
Can I Substitute Sweet Potatoes for Regular Potatoes?
Yes! Sweet potatoes add a nice sweetness and vibrant color. Slice them thinly just like regular potatoes, and follow the same baking instructions. Keep in mind the flavor will be slightly different but equally delicious.
