Ground Beef and Potato Casserole (Easy One-Pan Dinner)
This hearty ground beef and potato casserole comes together in one pan with simple ingredients you already have on hand. It's the ultimate easy beef dinner the whole family will ask for again and again.
The Ground Beef and Potato Dinner That Never Lets You Down
Some recipes just work, no matter how many times you make them. This ground beef and potato casserole is exactly that kind of dish. It is warm, filling, bubbling with melted cheddar, and comes together with ingredients most of us already keep on hand. If you have been searching for easy casserole recipes that actually satisfy a hungry household, this one belongs in your regular rotation.
This is not a fancy recipe. It is the kind of beef dinner that feels like a hug after a long day. Layers of thinly sliced potatoes, seasoned ground beef, creamy mushroom sauce, and a golden cheese crust on top. It is the definition of comfort food, and it feeds a crowd with almost no fuss.
Why This Recipe Works So Well
The secret to a great ground beef and potato casserole comes down to two things: even potato slices and a well-seasoned beef mixture that has real depth of flavor. Cutting the potatoes uniformly means everything cooks at the same rate, so you never end up with some layers mushy and others still firm.
The cream of mushroom soup and sour cream combo creates a sauce that keeps everything moist and cohesive without being heavy or gluey. Add smoked paprika to the beef and it transforms this from a basic weeknight dish into something that genuinely tastes like it took effort.
This is one of those beef recipes easy enough for a Tuesday but satisfying enough to serve at a Sunday family dinner.
Chef's Tip: Do not skip draining the fat after browning the beef. Excess grease will make the sauce oily and prevent the potatoes from absorbing all that good flavor.
The Tools That Make It Easier
Getting those potato slices thin and even is honestly the most important prep step in this recipe. The right equipment makes it effortless instead of tedious, and a good baking dish ensures even heat distribution from edge to center.
How to Build the Perfect Layers
Think of this casserole like a savory lasagna. You are building layers, and each one matters.
- Bottom layer: Potato slices, lightly seasoned. These will steam and soften from the bottom up.
- Middle layer: The ground beef mixture, rich with mushroom cream sauce and just enough cheese to bind it.
- Top layer: More potatoes, the rest of the beef, and a generous blanket of shredded cheddar that goes on during the final uncovered bake.
The foil-covered portion of the bake traps steam so the potatoes cook through completely. Removing the foil at the end lets the cheese go bubbly, golden, and slightly crisp at the edges. That contrast is everything.
Making It Your Own
This easy casserole is wonderfully flexible. A few easy variations worth trying:
- Stir in a cup of frozen corn or diced green bell pepper with the beef mixture for extra texture and color.
- Add a pinch of red pepper flakes if your household likes a little heat in their beef dishes.
- Swap cheddar for a blend of Gruyere and mozzarella for a more melty, pull-apart top.
- For a lighter version, use ground turkey instead of beef and reduced-fat sour cream. It still delivers on flavor.
Make It Vegetarian: Swap the ground beef for a mix of lentils and finely chopped mushrooms, use vegetable broth, and follow the rest of the recipe exactly. It is a surprisingly hearty vegetarische option that does not feel like a compromise.
Ready to Dig In?
This dish is best served straight from the oven after a short rest. Let it sit for about 10 minutes before cutting in so the layers hold together on the plate. Serve it alongside a simple green salad or some roasted green beans to round out the meal.
As far as fast dinners go, this one takes about an hour total but the oven does most of the work. You can even assemble it the night before and slide it straight into the oven after work. That is the kind of beef casserole recipe that genuinely makes weeknight life easier.

Ground Beef and Potato Casserole (Easy One-Pan Dinner)
This hearty ground beef and potato casserole comes together in one pan with simple ingredients you already have on hand. It's the ultimate easy beef dinner the whole family will ask for again and again.
Ingredients
- 1 1/2 lb ground beef, 80/20 blend recommended
- 2 lb Yukon Gold potatoes, peeled and sliced thin, about 0.25 inch thick
- 1 yellow onion, medium, diced
- 3 garlic cloves, minced
- 1 cup beef broth, low sodium
- 1 can cream of mushroom soup, 10.5 oz can, undiluted
- 1 1/2 cups shredded cheddar cheese, divided
- 1/2 cup sour cream, full fat preferred
- 1 tbsp olive oil, for browning
- 1 tsp smoked paprika
- 1/2 tsp garlic powder
- 1 tsp salt, or to taste
- 1/2 tsp black pepper, freshly ground
- 2 tbsp fresh parsley, chopped, for garnish
Instruction
Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13 inch baking dish and set aside.
Heat olive oil in a large skillet over medium-high heat. Add the diced onion and cook for 3 to 4 minutes until softened. Add the minced garlic and cook for another 30 seconds until fragrant.
Add the ground beef to the skillet. Break it apart with a wooden spoon and cook until no pink remains, about 6 to 8 minutes. Drain any excess fat.
Stir in the smoked paprika, garlic powder, salt, and black pepper. Mix well to coat the beef evenly.
Remove the skillet from heat and stir in the cream of mushroom soup, sour cream, and beef broth until fully combined.
Arrange half of the sliced potatoes in an even layer across the bottom of the prepared baking dish. Season lightly with a pinch of salt and pepper.
Spoon half of the ground beef mixture evenly over the potato layer. Sprinkle with half a cup of shredded cheddar cheese.
Layer the remaining potato slices on top, followed by the rest of the beef mixture. Cover tightly with aluminum foil.
Bake covered for 40 minutes, then remove the foil and sprinkle the remaining 1 cup of cheddar cheese over the top.
Return to the oven uncovered and bake for another 15 to 20 minutes, until the potatoes are fork-tender and the cheese is bubbly and golden.
Remove from the oven and let the casserole rest for 10 minutes before serving. Garnish with fresh chopped parsley and enjoy.
Equipment
- 9x13 inch baking dish
- Large skillet or saute pan
- Sharp knife and cutting board
- Mandoline slicer (optional, for even potato slices)
- Wooden spoon or spatula
- Aluminum foil
- Measuring cups and spoons
Notes
Storing and Reheating Leftovers
This casserole keeps beautifully. Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave on medium power for 2 to 3 minutes, or warm the whole dish covered with foil in a 325 degrees F oven for about 20 minutes.
One honest note: the potatoes do not freeze well after baking. The texture turns grainy once thawed, so this is best enjoyed fresh or from the fridge within a few days. Good thing it rarely lasts that long.
