Ground Beef Potato Casserole
There's something magical about a golden, bubbling casserole fresh from the oven-especially one built on layers of creamy Yukon Gold potatoes, savory ground beef, and melted Colby Jack cheese. Home cooks adore this dish for weeknight suppers when comfort trumps fuss, yet it's substantial enough to feed a crowd at potlucks or game-day gatherings. The rich mushroom sauce and tender potato slices make every bite deeply satisfying, while the gooey cheese top promises a hug in every forkful. It's the kind of recipe you'll want to make again and again, because leftovers taste even better the next day.
What Makes This Recipe Special
- The ultra-thin 1/8-inch potato slices ensure every bite has tender, creamy texture without turning mushy, even after baking.
- Using cream of mushroom soup and half-and-half together creates a velvety sauce that clings beautifully to the beef and potatoes, avoiding dryness.
- Layering the cheese between beef and potatoes (not just on top) delivers gooey pockets of melt in every bite, not just a blanket on the surface.
- Letting the casserole rest for 15 minutes after baking prevents a runny center-letting starches set so each portion holds its shape when served.

Instructions
1
Cut the Yukon gold potatoes into 1/8-inch thick slices and keep submerged in water to prevent discoloration.
2
Set oven to 350°F. Lightly coat a 9x13-inch baking dish with nonstick spray and reserve.
3
Sauté ground beef, diced onions, and minced garlic in a large saucepan over medium-high heat until the meat is well browned, breaking apart clumps as it cooks. Drain any rendered fat.
4
Combine cream of mushroom soup, half and half, onion powder, kosher salt, and black pepper in a medium bowl, whisking until completely smooth.
5
Drain the potato slices and layer one-third of them evenly in the prepared baking dish. Spread one-third of the beef mixture over the potatoes, then sprinkle with 3/4 cup shredded Colby Jack cheese and pour over one-third of the soup mixture.
6
Repeat layering process with another one-third of the potatoes, beef mixture, 3/4 cup cheese, and one-third of the soup mixture.
7
Arrange remaining potatoes and beef mixture as the top layer. Pour all remaining soup mixture evenly over the top and finish with the remaining 1.5 cups of shredded Colby Jack cheese.
8
Cover the dish tightly with aluminum foil and bake for 1 hour and 10 minutes.
9
Remove the foil and continue baking for an additional 20 minutes until bubbling and the top is golden.
10
Remove from oven and let the casserole stand for 15 minutes to set before portioning for service.
Essential Tips
Slice potatoes thin
Use a mandoline for consistent 1/8-inch slices to ensure even cooking and tender texture throughout the casserole. If you don't have one, sharpen your knife and take your time-thickness matters for doneness.
Brown the beef well
Cook the ground beef over medium-high heat until deeply browned and the onions are translucent. This builds flavor and prevents a greasy, watery sauce in the final dish.
Keep potatoes submerged
Soak sliced potatoes in cold water until ready to layer-this prevents browning and removes excess starch, which can make the casserole gummy.
Use fresh cheese
Shred Colby Jack cheese just before layering; pre-shredded cheese contains anti-caking agents that can make the casserole less gooey and more clumpy.
Cover tightly before baking
Tent the dish with foil during the first hour to steam the potatoes and prevent the top from drying out. Remove only after the initial bake for a golden finish.
Smart Swaps & Variations
Turkey or Chicken
Substitute 2 pounds of lean ground turkey or chicken for the beef to lighten the dish while keeping the same layered structure and sauce.
Vegetarian
Replace beef with 2 cups cooked lentils or 2 pounds crumbled firm tofu sautéed with umami-rich mushrooms and soy sauce for depth.
Spicy Kick
Add 1 teaspoon smoked paprika and 1/2 teaspoon cayenne pepper to the beef mixture for warmth, or top with pickled jalapeños before serving.
Creamy Herb
Mix 1 tablespoon fresh thyme or rosemary into the sauce and top with 1/2 cup grated Parmesan for a fresh, aromatic twist.
What to Serve With This
- Warm crusty sourdough bread or garlic dinner rolls to soak up the creamy sauce.
- A crisp green salad with a bright lemon vinaigrette to cut through the richness.
- Steamed green beans or roasted Brussels sprouts for a veggie balance.
- Cold glasses of iced tea or lemonade for a family-friendly meal.
Storage & Reheating
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. The casserole will firm up as it chills, making it easier to reheat in portions.
Reheating
Reheat covered in the oven at 325°F for 20-25 minutes until warmed through, adding a splash of half-and-half to refresh the sauce. Avoid microwaving-it can make the potatoes gummy.
Expert Chef Tips
- Use an instant-read thermometer to check doneness: the center should reach 165°F, ensuring both beef and potatoes are fully cooked without over-baking.
- For extra flavor, deglaze the beef pan with 1/4 cup red wine or beef stock before adding the cream of mushroom mixture-this intensifies the sauce's depth.
- Swap half the Colby Jack for sharp cheddar or pepper jack for a more complex flavor profile that cuts through the creaminess with a subtle kick.
Equipment You’ll Need
- Mandoline slicer (for uniform potato slices)

Frequently Asked Questions
Can I use instant potatoes instead of fresh?
Fresh Yukon Gold potatoes are essential for texture-they hold their shape and become creamy without turning gluey. Instant potatoes will result in a dry, pasty casserole.
My casserole is watery after baking. What went wrong?
Over-sliced or unsoaked potatoes release too much starch, or the beef wasn't browned enough, releasing moisture. Next time, blot the beef with a paper towel after cooking and rinse the potatoes well before slicing.
Can I make this ahead and bake later?
Yes! Assemble the casserole up to 24 hours ahead, cover tightly, and refrigerate. When ready to bake, let it sit at room temperature for 30 minutes before baking-add 10-15 minutes to the initial bake time.
What's the best way to reheat individual portions?
Reheat in a skillet over low heat with a splash of broth or cream, covered, to refresh the sauce and texture. Microwaving works in a pinch but can make the potatoes rubbery.
Can I freeze this casserole?
Absolutely. Freeze assembled (unbaked) or baked casserole for up to 3 months. Thaw overnight in the fridge before baking-add 10-15 minutes to the bake time if frozen.
Is there a substitute for cream of mushroom soup?
Yes. Blend 1 cup milk with 3 tablespoons flour, 1/2 cup finely chopped mushrooms, and 1 tablespoon soy sauce for a homemade version with cleaner ingredients.
How do I prevent the top from burning?
Tent the dish with foil for the first hour, then remove only for the last 20 minutes. Place a baking sheet underneath the casserole if your oven runs hot.
Can I use pre-shredded cheese?
It's not recommended-pre-shredded cheese contains anti-caking agents that inhibit melting. Freshly shredded cheese melts smoothly, creating those coveted gooey layers.
