Step-by-Step Instructions
Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C).
Lightly grease a 9 × 13-inch (23 × 33 cm) baking dish with vegetable oil or cooking spray and set it aside.
Cook the Onion
Heat the vegetable oil in a large deep skillet over medium-high heat.
Add the diced onion and cook for about 3 minutes, stirring occasionally, until softened and translucent.
Brown the Ground Beef
Add the ground beef to the skillet.
Break it apart with a wooden spoon and cook for approximately 7–8 minutes, stirring frequently, until completely browned.
Drain any excess fat from the skillet.
Season the Beef
Add the minced garlic, smoked paprika, salt, and black pepper.
Cook for about 1 minute, stirring constantly, until the garlic becomes fragrant.
Add the Sauce
Pour the tomato sauce and beef broth into the skillet.
Stir well to combine everything.
Reduce the heat to low and simmer for approximately 5 minutes, allowing the sauce to thicken slightly and the flavors to come together.
Build the First Layer
Spread half of the beef mixture evenly across the bottom of the prepared baking dish.
Add the Potatoes
Arrange the thinly sliced potatoes over the beef mixture, slightly overlapping each slice.
Try to distribute the potatoes evenly so they cook at the same rate.
Add the Remaining Beef
Spread the remaining beef sauce evenly over the potatoes.
Cover the baking dish tightly with aluminum foil.
Bake Covered
Place the covered casserole in the preheated oven and bake for approximately 30–35 minutes.
The potatoes should become tender enough to pierce easily with a fork.
Add the Cheese
Carefully remove the aluminum foil.
Sprinkle the grated cheddar and mozzarella evenly over the entire surface.
Finish Baking
Return the uncovered casserole to the oven.
Bake for another 15–20 minutes, or until the cheese is completely melted, bubbling, and lightly golden.
For an extra golden top, you can place the casserole under the broiler for 1–2 minutes, watching it carefully to prevent burning.
Rest Before Serving
Remove the casserole from the oven and let it rest for approximately 5–10 minutes before serving.
This allows the layers to settle and makes the casserole easier to portion.
Best Tips
Slice the potatoes as evenly as possible. Pieces that are approximately ¼ inch (6 mm) thick are ideal for this recipe.
A mandoline slicer can make it easier to achieve consistent slices, but a sharp kitchen knife works perfectly well.
Freshly grated cheese usually melts more smoothly than many pre-shredded varieties, so grating the cheddar and mozzarella yourself is recommended.
Make sure to drain excess fat from the ground beef after browning. This helps keep the casserole rich without making it unnecessarily greasy.
Keep the casserole covered during the first stage of baking. The trapped steam helps the potatoes cook until tender.
Allow the finished casserole to rest for a few minutes before cutting into it. This helps the layers hold together.
Best Ingredient Options
Potatoes
Russet potatoes are an excellent choice because they become tender and absorb the flavorful sauce.
Yukon Gold potatoes are another great option and provide a slightly creamier texture.
Ground Beef
A 90% lean ground beef works particularly well because it provides plenty of flavor without producing excessive grease.
Cheese
Cheddar provides a sharp, savory flavor, while mozzarella contributes excellent melting and stretch.
For an even richer topping, you can combine cheddar, mozzarella, and a little Monterey Jack.
Tomato Sauce
Use a plain tomato sauce or a lightly seasoned variety. Avoid sauces that are heavily sweetened because they can make the casserole taste unbalanced.
Recipe Variations
Add Vegetables
Add diced bell peppers, mushrooms, peas, corn, or finely grated carrots to the beef mixture.
Cook firmer vegetables with the onion before adding the ground beef.
Make It Spicy
Add ¼–½ teaspoon of crushed red pepper flakes or a pinch of cayenne pepper to the beef sauce.
Change the Cheese
Try Monterey Jack, Colby Jack, provolone, or a Mexican-style cheese blend instead of some or all of the cheddar.
Creamier Casserole
For a creamier version, stir ½ cup of sour cream or cream cheese into the beef sauce after removing it from the heat.
Sweet Potato Version
Replace the Russet potatoes with thinly sliced sweet potatoes for a slightly sweeter flavor and colorful presentation.
What to Serve With
Because this casserole is hearty and filling, it pairs especially well with lighter side dishes.
A crisp green salad with a simple lemon vinaigrette provides freshness and acidity.
Steamed green beans, roasted broccoli, or asparagus are also excellent choices.
For a more substantial meal, serve it with warm crusty bread or dinner rolls.
Make-Ahead Instructions
The casserole can be assembled up to 24 hours in advance.
Prepare the beef sauce and assemble the casserole as directed, but leave off the cheese topping.
Cover tightly and refrigerate.
When ready to bake, remove the casserole from the refrigerator while the oven preheats.
Because the ingredients are cold, you may need to add approximately 5–10 minutes to the covered baking time.
Add the cheese during the final baking stage.
Storage
Allow leftovers to cool, then transfer them to an airtight container.
Store in the refrigerator for up to 4 days.
For the best texture, store individual portions separately so they are easy to reheat.
Reheating
Microwave
Place an individual portion on a microwave-safe plate.
Cover loosely and heat for approximately 2–3 minutes, checking halfway through.
Continue heating until the center is thoroughly hot.
Oven
Place the casserole or individual portions in an oven-safe dish.
Cover loosely with aluminum foil and heat at 350°F (175°C) for approximately 15–25 minutes, depending on the portion size.
Freezing
The casserole can be frozen for up to 3 months.
For best results, cool it completely before wrapping it tightly in freezer-safe packaging.
If possible, freeze individual portions for convenient reheating.
Thaw overnight in the refrigerator before reheating.
The texture of the potatoes may be slightly softer after freezing, but the casserole will still be delicious.
Common Mistakes to Avoid
Cutting the Potatoes Too Thick
Very thick potato slices may remain firm while the rest of the casserole is finished.
Aim for slices around ¼ inch (6 mm) thick.
Skipping the Covered Baking Stage
The foil traps steam and helps cook the potatoes. Removing it too early can leave the potatoes undercooked.
Using Too Much Liquid
The beef sauce should be flavorful and moist but not excessively watery. Too much liquid can make the finished casserole loose.
Not Draining the Beef
Excess fat can make the casserole greasy, especially when combined with the melted cheese.
Adding Cheese Too Early
Adding the cheese from the beginning can cause it to become overly browned before the potatoes are completely tender.
