Ground Beef and Potatoes Casserole is a hearty, comforting dish that’s perfect for those days when you want something filling and simple. It brings together tender ground beef, soft potatoes, and a flavorful sauce, all baked until bubbly and golden on top. The mix of textures—from the smooth mashed potatoes to the savory beef—makes it a real crowd-pleaser.
I love making this casserole because it’s one of those recipes that feels like a warm hug on a plate. It’s super easy to throw together, and I usually make a big batch so we have leftovers for the next day. One trick I like is to season the beef well with garlic and onion powder to really bring out the flavor without too much fuss.
My favorite way to serve this is with a simple green salad on the side to balance out all that richness. It’s perfect for family dinners or when friends come over because it’s both cozy and satisfying. Plus, it’s a great way to use up potatoes in the fridge! Every time I make it, I’m reminded of those slow, relaxed weekend meals where everyone gathers around the table and enjoys good, no-fuss food together.
Key Ingredients & Substitutions
Ground Beef: This is the heart of the casserole. You can swap it for ground turkey or chicken for a lighter dish. If you prefer plant-based, try lentils or crumbled tofu with similar seasoning.
Potatoes: Thin slices cook evenly and absorb flavor well. Yukon Gold or red potatoes work best because they hold shape but get tender. Russets can be used but may become softer.
Cheese: Sharp cheddar gives great flavor and meltiness. You can mix in mozzarella for a stretchier texture or use a dairy-free cheese if needed.
Tomatoes: Canned diced tomatoes add moisture and tang. If fresh aren’t available, use tomato sauce or omit for a milder taste, adding a bit more broth.
How Do You Make Sure the Potatoes Cook Through in the Casserole?
Cooking potatoes fully inside a layered casserole can be tricky. Here’s how to get tender potatoes every time:
- Slice Potatoes Thinly: Aim for about 1/8 inch thick slices so they cook evenly and quickly.
- Layer Evenly: Spread layers uniformly to help heat circulate around each slice.
- Add Moisture: The beef broth and tomatoes help steam the potatoes inside the oven.
- Cover While Baking: Use foil initially to trap steam and soften potatoes.
- Test for Doneness: Poke with a fork near the end of baking to check tenderness before adding cheese.
Equipment You’ll Need
- Large skillet – perfect for browning ground beef and sautéing onions evenly.
- Sharp knife and cutting board – for slicing potatoes thinly and chopping onions safely.
- 9×13 inch baking dish – roomy enough to layer everything and bake evenly.
- Aluminum foil – helps keep moisture in during baking so potatoes cook well.
- Spatula or wooden spoon – great for stirring the beef mixture without scratching the pan.
Flavor Variations & Add-Ins
- Try ground turkey or chicken instead of beef for a lighter, milder casserole.
- Add diced bell peppers or mushrooms to the beef mixture for extra veggies and flavor.
- Mix in shredded mozzarella with cheddar on top for a gooey, stretchy finish.
- Sprinkle smoked paprika or chili powder into the beef mixture for a smoky or spicy kick.
How to Make Ground Beef and Potatoes Casserole
Ingredients You’ll Need:
- 1 ½ pounds ground beef
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 (14.5 oz) can diced tomatoes, drained
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon paprika (optional)
- 1 teaspoon dried oregano
- 3 pounds potatoes, peeled and thinly sliced
- 2 cups shredded sharp cheddar cheese
- ¼ cup green onions or fresh parsley, chopped (for garnish)
- 2 tablespoons olive oil or butter
- 1 cup beef broth or water
- 1 tablespoon tomato paste (optional, for richer flavor)
How Much Time Will You Need?
This dish takes about 20 minutes to prepare, including chopping and cooking the beef mixture, plus 1 hour baking time. Overall, plan for about 1 hour and 20 minutes from start to ready-to-serve.
Step-by-Step Instructions:
1. Prepare the Beef Mixture:
Preheat your oven to 375°F (190°C). In a large skillet, heat the olive oil or butter over medium heat. Add the chopped onion and sauté until soft and translucent, about 5 minutes. Stir in minced garlic and cook 1 minute more until fragrant. Add ground beef and cook for 7-10 minutes, breaking it up with a spoon, until browned. Drain excess fat if needed.
Mix in drained diced tomatoes, salt, pepper, paprika, oregano, and tomato paste if using. Pour in broth or water and let simmer for 5 minutes to blend flavors and thicken slightly. Remove from heat.
2. Assemble the Casserole:
Lightly grease a 9×13 inch baking dish. Spread a layer of thinly sliced potatoes over the bottom. Spoon half the beef mixture evenly on top. Add another layer of potato slices, then the remaining beef mixture. Finish with a final potato layer on top.
3. Bake and Finish:
Cover the casserole tightly with aluminum foil and bake for 45 minutes. Remove the foil and evenly sprinkle shredded cheddar over the top layer of potatoes. Return the dish to the oven, uncovered, for an additional 15 minutes, or until cheese is bubbly and golden.
Remove from the oven, let the casserole rest for 5-10 minutes to set, then garnish with chopped green onions or parsley before serving.

Can I Use Frozen Ground Beef for This Casserole?
Yes, you can, but be sure to fully thaw it first. Thaw overnight in the fridge or use the defrost setting on your microwave. Cooking with thawed beef ensures even browning and better texture.
Can I Prepare the Casserole Ahead of Time?
Absolutely! Assemble the casserole up to step 9, then cover and refrigerate for up to 24 hours. When ready to bake, add the cheese topping and bake as directed, adding a few extra minutes if baking from cold.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through. For best texture, cover with foil if reheating in the oven to prevent drying out.
What Can I Serve with This Casserole?
This casserole pairs well with a fresh green salad or steamed vegetables to add brightness and balance the rich flavors. A side of crusty bread also complements the meal nicely.
