Step-by-Step Instructions
1. Prepare the Oven and Baking Dish
Preheat your oven to 190°C (375°F).
Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of oil. Set it aside.
2. Prepare the Potatoes
Peel the potatoes and slice them into approximately ¼-inch-thick rounds.
Try to keep the slices as uniform as possible so they cook evenly. Set the sliced potatoes aside while you prepare the beef mixture.
3. Brown the Ground Beef
Heat a large skillet over medium-high heat.
Add the ground beef and diced onion. Cook for approximately 6–8 minutes, breaking the meat apart with a wooden spoon, until the beef is completely browned and the onion is tender.
Drain excess grease if necessary.
4. Add the Garlic and Seasonings
Add the minced garlic, Italian seasoning, salt, and black pepper.
Cook for another 30–60 seconds, stirring constantly, until the garlic becomes fragrant.
5. Add the Sauce
Pour the tomato sauce and beef broth into the skillet.
Stir everything together and allow the mixture to simmer gently for about 3–5 minutes. This allows the flavors to combine and creates a flavorful sauce for the casserole.
Remove the skillet from the heat.
6. Assemble the First Layer
Arrange approximately half of the sliced potatoes in an even layer across the bottom of the prepared baking dish.
Slightly overlap the potato slices if necessary, but avoid creating extremely thick layers.
7. Add the Beef Mixture
Spread approximately half of the seasoned ground beef and tomato mixture evenly over the potatoes.
Sprinkle about ½ cup of mozzarella cheese over the beef.
8. Create the Second Layer
Add the remaining sliced potatoes over the first layer.
Spread the remaining beef and tomato mixture evenly over the potatoes.
Cover the top with the remaining mozzarella and all of the shredded cheddar cheese.
9. Cover and Bake
Cover the baking dish tightly with aluminum foil.
Bake at 190°C (375°F) for 40 minutes.
Covering the casserole helps trap steam, allowing the potatoes to become tender without drying out the beef mixture.
10. Finish Baking Uncovered
Carefully remove the aluminum foil.
Return the casserole to the oven and bake for another 15–20 minutes, or until the potatoes are completely tender and the cheese is melted, golden, and bubbling.
For an extra-golden cheese topping, you can switch the oven to broil for 1–2 minutes at the end. Watch carefully so the cheese does not burn.
11. Rest Before Serving
Remove the casserole from the oven and let it rest for approximately 10 minutes before serving.
This short resting period allows the layers to settle and makes the casserole easier to portion.
Best Tips for Success
For the best results, slice the potatoes evenly. Thin, uniform slices cook more consistently and prevent some pieces from remaining firm while others become overcooked.
Use freshly shredded cheese whenever possible. It generally melts more smoothly and creates a better bubbly, golden topping.
Do not skip the resting period. Allowing the casserole to sit for about 10 minutes helps the sauce thicken slightly and keeps the layers together when served.
If your potatoes are particularly large or thick, they may require a few additional minutes of baking time.
Best Ingredient Options
Ground beef: Lean ground beef works beautifully, but you can use regular ground beef and drain the excess fat after browning.
Potatoes: Russet potatoes are ideal because they become tender and absorb the savory sauce. Yukon Gold potatoes are another excellent option and have a naturally buttery texture.
Cheese: Mozzarella provides excellent meltability, while sharp cheddar adds stronger flavor. You can also use Monterey Jack, Colby, or a Mexican-style cheese blend.
Tomato sauce: Plain tomato sauce keeps the recipe simple, but you can substitute marinara sauce for additional herbs and flavor.
Recipe Variations
For a creamy ground beef and potato casserole, replace part of the tomato sauce with a small amount of cream or sour cream.
For a spicy version, add ½ teaspoon of red pepper flakes or diced jalapeños to the beef mixture.
For extra vegetables, add diced bell peppers, mushrooms, zucchini, or frozen mixed vegetables.
You can also turn this into a loaded cheeseburger potato casserole by adding a little Worcestershire sauce to the beef and topping the finished casserole with chopped pickles and green onions.
What to Serve With This Casserole
This hearty casserole pairs wonderfully with a crisp green salad, steamed broccoli, roasted vegetables, or fresh green beans.
For a more substantial family dinner, serve it with warm dinner rolls or crusty bread to soak up the flavorful sauce.
A simple side salad with a light vinaigrette also provides a refreshing contrast to the rich beef, potatoes, and cheese.
Make-Ahead Instructions
You can assemble the casserole several hours ahead of time.
Cover it tightly and refrigerate until you are ready to bake. Remove it from the refrigerator while the oven preheats.
Because the casserole is starting cold, it may require approximately 5–10 additional minutes of baking time.
Storage
Allow leftover casserole to cool before transferring it to an airtight container.
Store in the refrigerator for up to 3–4 days.
For convenient meal prep, divide leftovers into individual portions before refrigerating.
Reheating
For individual portions, microwave for approximately 2–3 minutes, stirring or rotating halfway through if needed.
For larger portions, place the casserole in an oven-safe dish, cover with foil, and reheat at 175°C (350°F) until heated through.
Adding a small splash of beef broth before reheating can help keep the casserole moist.
Freezing
This casserole can be frozen, although the texture of the potatoes may become slightly softer after thawing.
Allow it to cool completely before wrapping it tightly with plastic wrap and aluminum foil or placing it in a freezer-safe airtight container.
Freeze for up to 2–3 months for best quality.
Thaw overnight in the refrigerator before reheating.
Common Mistakes to Avoid
Cutting the potatoes too thick: Thick slices take much longer to become tender. Aim for approximately ¼-inch slices.
Skipping the foil: Baking uncovered from the beginning can cause the cheese to brown too quickly while the potatoes are still firm.
Using too much liquid: Excess sauce can make the casserole watery. Stick closely to the recommended measurements.
Not draining very fatty beef: Too much grease can make the finished casserole heavy and oily.
Cutting immediately: Give the casserole about 10 minutes to rest so the layers can settle before serving.

Frequently Asked Questions
Can I use ground turkey instead of ground beef?
Yes. Ground turkey is an excellent substitute if you prefer a lighter meat option. Because turkey is usually leaner, make sure the sauce provides enough moisture to keep the casserole flavorful.
Can I prepare this casserole without peeling the potatoes?
Absolutely. If you prefer, you can leave the potato skins on. Just scrub the potatoes thoroughly before slicing.
Why are my potatoes still hard?
The most common reasons are slices that are too thick, insufficient baking time, or a dish that was not covered during the initial baking stage. Slice the potatoes thinly and cover the casserole for the first 40 minutes.
Can I use pre-shredded cheese?
Yes, although freshly shredded cheese generally melts more smoothly. Pre-shredded cheese is perfectly acceptable when convenience is important.
Can I add vegetables?
Definitely. Bell peppers, mushrooms, peas, corn, spinach, or zucchini can all work well. Sauté vegetables with the beef and onion before assembling the casserole.
How do I know when the casserole is finished?
The potatoes should be fork-tender, and the cheese should be completely melted and bubbling with a lightly golden surface.
