How to Make Ground Beef and Potato Casserole
1. Preheat the Oven
Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with butter or cooking spray so the casserole does not stick.
Starting with a properly heated oven helps the casserole cook evenly from the beginning.
2. Brown the Ground Beef
Heat a large skillet over medium heat. Add the ground beef and chopped onion. Cook for 6 to 8 minutes, breaking the beef apart with a spoon, until the meat is browned and the onion is soft.
Stir in the garlic, salt, black pepper, and paprika. Cook for another 30 seconds until fragrant. If there is a lot of grease in the skillet, drain the excess.
This step gives the casserole its main savory flavor, so it is worth seasoning the beef well.
3. Mix the Creamy Sauce
In a medium bowl, stir together the cream of mushroom soup, milk, and sour cream until smooth.
The mixture should be creamy and spreadable, not too thick. If it seems overly dense, add a splash more milk to loosen it slightly.
4. Slice the Potatoes
Wash and peel the potatoes if you prefer, then slice them thinly and as evenly as possible.
Thin, even slices are important because they help the potatoes cook through in the same amount of time. A mandoline is helpful here, but a sharp knife works just fine if you cut carefully.
5. Layer the Casserole
Arrange half of the sliced potatoes in the bottom of the prepared baking dish. Spread half of the cooked ground beef mixture over the potatoes. Spoon some of the creamy sauce over the top, then sprinkle with about 1 cup of the shredded cheese.
Repeat with the remaining potatoes, remaining beef mixture, the rest of the creamy sauce, and the remaining cheese.
Layering keeps the flavors distributed evenly and helps every serving have a little of everything.
6. Cover and Bake
Cover the baking dish tightly with aluminum foil and bake for 40 minutes.
This covered stage is important because it traps steam and helps the potatoes become tender instead of drying out.
7. Uncover and Finish Baking
Remove the foil and bake for another 15 to 20 minutes, or until the cheese is melted and lightly golden and the potatoes are fork-tender.
If you want a bit more color on top, you can broil the casserole for 1 to 2 minutes at the end, but watch it closely.
8. Rest and Serve
Let the casserole rest for 5 to 10 minutes before serving. Garnish with chopped parsley if using.
This short rest helps the layers settle and makes it easier to scoop neat portions.
Tips for the Best Ground Beef and Potato Casserole
Slice the Potatoes Thinly
This is one of the most important details in the recipe. Thin slices cook more evenly and help prevent undercooked potatoes in the center.
Drain Excess Grease
If your ground beef releases a lot of fat, drain it before layering. That keeps the casserole rich but not greasy.
Season Every Layer
The beef should be well seasoned, and the creamy layer should also have flavor from the soup and dairy. That layered seasoning makes the final dish taste more complete.
Cover Tightly While Baking
The foil helps the potatoes steam and soften. If the casserole is left uncovered the whole time, the top may brown before the potatoes are ready.
Let It Rest Before Serving
Straight from the oven, casseroles are often too loose. A short rest helps the sauce settle and improves the texture.
Easy Variations
This casserole is flexible, which is one of the reasons it is so useful.
Add Vegetables
Mushrooms, peas, corn, or green beans can be added between layers for more texture and flavor.
Use a Different Cheese
Cheddar is classic, but Monterey Jack, Colby Jack, or a cheddar blend all work well.
Swap the Soup
Cream of chicken or cream of celery can replace cream of mushroom if that is what you have in the pantry.
Add Extra Herbs
A little dried thyme, Italian seasoning, or parsley can give the casserole a more herb-forward flavor.
Make It Richer
A little extra sour cream or an added layer of cheese will make the casserole even creamier if that is your preference.
What to Serve with Ground Beef and Potato Casserole
Because this casserole is hearty, simple side dishes usually work best.
Green salad
Roasted broccoli
Steamed green beans
Glazed carrots
Dinner rolls
Cucumber salad
If I am serving this for dinner, I usually pair it with something fresh and green to balance the richness of the casserole.
