How to Make Ground Beef Potato Casserole
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish with butter or nonstick cooking spray.
Set the dish aside while preparing the ingredients.
Step 2: Brown the Ground Beef
Place a large skillet over medium-high heat.
Add the ground beef, finely diced onion, and minced garlic.
Cook for approximately 7–10 minutes, breaking the beef into small pieces with a wooden spoon as it browns.
Once the beef is fully cooked and no longer pink, drain any excess grease.
Season with salt, black pepper, paprika, and dried thyme if using.
Stir well to distribute the seasonings evenly, then remove the skillet from the heat.
Step 3: Prepare the Creamy Sauce
In a medium mixing bowl, combine the cream of mushroom soup and whole milk or half-and-half.
Whisk until the mixture becomes smooth and creamy.
Make sure there are no large lumps remaining. This sauce will add moisture to the potatoes and help bring all the flavors together.
Step 4: Slice the Potatoes
Peel the russet potatoes and slice them into thin, even rounds.
Aim for slices approximately ⅛ inch thick so they cook evenly in the oven.
A mandoline slicer can make this step easier, but a sharp knife works perfectly too.
Keep the slices as uniform as possible to avoid having some potatoes undercooked while others become too soft.
Step 5: Assemble the First Layer
Arrange half of the sliced potatoes in an even layer across the bottom of the prepared baking dish.
Spread half of the seasoned ground beef mixture over the potatoes.
Pour half of the creamy mushroom sauce evenly over the beef and potatoes.
Sprinkle 1 cup of shredded cheddar cheese over the top.
Step 6: Add the Second Layer
Repeat the layering process with the remaining ingredients.
Add the remaining sliced potatoes, followed by the rest of the ground beef.
Pour the remaining creamy mushroom sauce over everything.
Finish with the remaining 1 cup of shredded cheddar cheese.
Scatter the small cubes of butter evenly across the top.
Step 7: Bake the Casserole
Cover the baking dish tightly with aluminum foil.
Place it in the preheated oven and bake for approximately 40 minutes.
The foil helps trap moisture and steam the potatoes until tender.
After 40 minutes, carefully remove the foil and return the casserole to the oven.
Bake uncovered for another 20 minutes, or until the potatoes are fork-tender and the cheese is melted, golden, and bubbly.
If you want a slightly crispier cheese topping, broil for an additional 1–2 minutes, watching carefully to prevent burning.
Step 8: Rest and Serve
Remove the casserole from the oven and allow it to rest for approximately 10 minutes before serving.
This resting time helps the creamy sauce settle and makes the casserole easier to slice.
Garnish with freshly chopped parsley.
Serve warm and enjoy every delicious layer of tender potatoes, savory beef, creamy sauce, and melted cheddar cheese.
Tips for the Best Hamburger Potato Casserole
Slice the potatoes evenly: Thin, uniform potato slices are important for even cooking. A mandoline slicer is especially helpful.
Choose the right potatoes: Russet potatoes work beautifully because they become tender and absorb the creamy sauce. Yukon Gold potatoes are another excellent option.
Drain excess grease: After browning the beef, remove excess fat to prevent the casserole from becoming greasy.
Season the beef well: Don’t skip the onion, garlic, paprika, and black pepper. They add wonderful flavor to the entire dish.
Use freshly shredded cheese: Freshly shredded cheddar melts beautifully and creates a smoother, creamier topping than many pre-shredded varieties.
Cover during the first baking stage: Keeping the dish covered helps the potatoes cook through without drying out.
Check the potatoes before removing the casserole: Insert a fork or knife into the center. It should slide through the potato slices easily.
Let it rest before serving: A short resting period helps the layers hold together and makes serving much easier.
Variations and Substitutions
Ground Beef and Potato Casserole with Cream Cheese
For an extra creamy version, add 3–4 ounces of softened cream cheese to the mushroom soup and milk mixture. Whisk until smooth before layering.
Cheesy Ground Beef Potato Casserole
If you love extra cheese, add a layer of mozzarella along with the cheddar. The mozzarella creates a delicious stretchy cheese texture, while cheddar provides a stronger flavor.
Ground Beef Potato Casserole with Vegetables
Add a layer of frozen peas, corn, green beans, or finely chopped carrots between the beef and potato layers. This is an easy way to add extra vegetables.
Ground Beef Potato Casserole Without Cream of Mushroom Soup
If you prefer not to use canned soup, replace the mushroom soup and milk with approximately 1½ cups of homemade béchamel or creamy cheese sauce.
Season the sauce with salt, black pepper, and a little garlic powder for extra flavor.
Ground Turkey Potato Casserole
Replace the ground beef with ground turkey or chicken for a lighter alternative. Season well to keep the meat flavorful.
Ground Beef Potato Casserole with Bacon
Cook and crumble 4–5 slices of bacon and sprinkle them between the layers or over the cheese topping before baking. Bacon adds a smoky, savory flavor.
Spicy Hamburger Potato Casserole
Add ½ teaspoon of chili powder or a pinch of red pepper flakes to the ground beef mixture for a little heat.
What to Serve with Ground Beef Potato Casserole
This hearty casserole can easily stand on its own, but a few simple side dishes make the meal even more delicious.

- Steamed green beans: Add freshness and color to your dinner plate.
- Roasted broccoli: A delicious vegetable side that pairs perfectly with melted cheddar.

Make-Ahead Instructions
Ground Beef Potato Casserole is an excellent make-ahead dinner.
You can prepare the ground beef mixture, slice the potatoes, and mix the creamy sauce in advance.
For the best texture, assemble the casserole shortly before baking. If assembling it completely ahead of time, cover tightly and refrigerate, then bake within 24 hours.
When baking directly from the refrigerator, allow approximately 10–15 extra minutes of cooking time, checking that the potatoes are completely tender and the center is thoroughly heated.
Storage and Reheating Instructions
Refrigerator: Allow leftover casserole to cool and transfer it to an airtight container. Refrigerate for up to 3–4 days.
Oven Reheating: Place individual portions in an oven-safe dish, cover with foil, and reheat at 350°F (175°C) for approximately 15–20 minutes, or until heated through.
Microwave Reheating: Place a portion on a microwave-safe plate and heat in 1-minute intervals until thoroughly warm.
Freezing: For best results, assemble the unbaked casserole in a freezer-safe baking dish, wrap it tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking according to the recipe instructions.
You can also freeze cooked portions in airtight containers, although the potatoes may become slightly softer after thawing.
Frequently Asked Questions
What potatoes are best for ground beef potato casserole?
Russet potatoes and Yukon Gold potatoes are both excellent choices. Russet potatoes become soft and absorb the creamy sauce, while Yukon Gold potatoes have a naturally buttery texture and hold their shape well.
Do I need to cook the potatoes before assembling the casserole?
No. The potatoes are sliced thinly and cook directly in the oven with the beef and creamy sauce. Covering the casserole during the first 40 minutes helps them become tender.
Why are my potatoes still hard after baking?
The potatoes may be sliced too thickly, or the casserole may need additional baking time. Make sure the dish is tightly covered during the first baking stage and check the center with a fork before removing it from the oven.
If the potatoes are still firm, cover the dish again and continue baking until tender.
Can I make ground beef potato casserole ahead of time?
Yes! You can assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. Add approximately 10–15 extra minutes to the baking time if starting with a cold casserole.
Can I use ground turkey instead of ground beef?
Absolutely! Ground turkey or ground chicken can replace the beef. Brown the meat with the onions and garlic, season well, and follow the same layering and baking instructions.
Can I use a different cheese?
Yes! Cheddar is a classic choice, but mozzarella, Colby Jack, Monterey Jack, or a combination of cheeses will also work beautifully.
Can I make this casserole without cream of mushroom soup?
Yes. You can replace the canned soup and milk with approximately 1½ cups of homemade béchamel or cheese sauce.
How do I keep the casserole from becoming watery?
Drain excess grease from the browned beef and avoid adding extra liquid beyond the recipe measurements. Also, allow the casserole to rest for about 10 minutes after baking so the sauce can settle.
Can I add vegetables to this casserole?
Definitely! Frozen peas, corn, green beans, and sautéed mushrooms are delicious additions. Add them between the layers for extra flavor and variety.
How do I know when the casserole is fully cooked?
The potatoes should be completely tender when pierced with a fork, the cheese should be melted and bubbly, and the center should be thoroughly heated. If using a food thermometer, the center should reach 165°F (74°C).
