Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish with butter or cooking spray and set it aside.
2. Prepare the Potatoes
Peel the potatoes and slice them into thin, even slices approximately 1/4 inch (6 mm) thick.
Try to keep the slices similar in thickness so they cook evenly.
If you are preparing the potatoes ahead of time, keep the slices submerged in cold water to help prevent discoloration. Drain and pat them thoroughly dry before layering.
3. Cook the Ground Beef
Place a large skillet over medium-high heat.
Add the ground beef and diced onion.
Cook for approximately 7–10 minutes, breaking the beef apart with a wooden spoon as it cooks.
Continue until the beef is fully browned and the onion becomes soft and translucent.
Add the minced garlic and cook for another 1 minute, stirring constantly until fragrant.
Drain any excess grease from the skillet.
Set the cooked beef mixture aside.
4. Make the Creamy Cheese Sauce
Place a medium saucepan over medium heat.
Add the butter and allow it to melt.
Whisk in the flour and cook for approximately 1 minute, stirring constantly. This creates the base of the sauce.
Gradually pour in the whole milk while whisking continuously.
Slowly add the heavy cream and continue whisking to keep the sauce smooth.
Bring the mixture to a gentle simmer.
Cook for approximately 3–5 minutes, stirring frequently, until the sauce thickens enough to lightly coat the back of a spoon.
5. Add the Cheese and Seasonings
Remove the saucepan from the heat.
Add 1 1/2 cups of the shredded cheddar cheese.
Stir until the cheese melts completely into the sauce.
Add the salt, black pepper, garlic powder, and onion powder.
Taste the sauce and adjust the seasoning if needed.
6. Assemble the First Layer
Arrange approximately half of the sliced potatoes evenly across the bottom of the prepared baking dish.
Try to create an even layer without leaving large gaps.
Spread half of the cooked ground beef and onion mixture over the potatoes.
Pour approximately half of the cheese sauce evenly over the beef and potatoes.
7. Repeat the Layers
Add the remaining sliced potatoes over the first layer.
Spread the remaining ground beef mixture evenly across the potatoes.
Pour the remaining cheese sauce over the top.
Use a spatula or the back of a spoon to spread the sauce as evenly as possible.
8. Cover and Bake
Cover the baking dish tightly with aluminum foil.
Place it in the preheated 375°F (190°C) oven.
Bake for 45 minutes.
The foil traps steam inside the dish, helping the potatoes cook until tender.
9. Finish Baking Uncovered
After 45 minutes, carefully remove the foil.
Return the casserole to the oven.
Continue baking uncovered for another 25–30 minutes, or until the potatoes are completely tender when pierced with a fork and the top is bubbling.
The edges should be lightly golden and the sauce should be visibly bubbling.
10. Add the Final Cheese
Remove the casserole from the oven.
Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top.
Cover the casserole loosely and let it stand for approximately 3 minutes, allowing the residual heat to melt the cheese.
11. Garnish and Serve
Remove the cover and sprinkle freshly chopped parsley over the top.
Allow the casserole to rest for approximately 5–10 minutes before slicing.
This short resting period allows the creamy sauce to settle slightly and makes the casserole easier to serve.
Serve warm.
Best Tips
Use a mandoline slicer or a sharp knife to create evenly thin potato slices. Consistent thickness is one of the most important factors for ensuring that all the potatoes become tender at the same time.
Freshly shredding the cheddar cheese is recommended because it melts smoothly into the sauce and creates a creamier consistency.
When making the cheese sauce, add the milk and cream gradually while whisking. This helps prevent lumps and produces a smooth sauce.
Do not skip the covered portion of the baking time. The trapped steam is important for cooking the potato layers until tender.
Allow the casserole to rest for several minutes before serving. Cutting immediately can cause the creamy sauce to spread too quickly.
Best Ingredient Options
Ground Beef
An 80/20 ground beef blend provides excellent flavor and moisture. If you prefer a leaner casserole, 85/15 or 90/10 ground beef can also be used.
Potatoes
Yukon Gold potatoes provide a naturally buttery and creamy texture. Russet potatoes are another excellent choice because they become soft and fluffy while absorbing the cheese sauce.
Cheddar Cheese
Sharp cheddar provides a bold cheese flavor, while mild cheddar gives the casserole a softer, creamier taste.
A combination of cheddar and Monterey Jack can also be used for an especially smooth and melty topping.
Cream
Heavy cream gives the sauce a rich consistency. For a slightly lighter version, you can replace part of the heavy cream with additional whole milk.
Recipe Variations
Loaded Beef and Potato Casserole
Add sliced green onions and extra cheddar cheese to the finished casserole for a loaded baked-potato-inspired version.
Mushroom Beef Casserole
Sauté sliced mushrooms with the onion and ground beef for an earthy flavor that pairs beautifully with the creamy cheese sauce.
Spicy Beef Potato Casserole
Add crushed red pepper flakes, cayenne pepper, or diced jalapeños to the beef mixture for a spicy variation.
Extra Cheesy Version
For an especially cheesy casserole, increase the cheddar to 2 1/2 cups and add some cheese between the potato layers.
Vegetable Version
Add thinly sliced bell peppers, mushrooms, spinach, or broccoli to incorporate additional vegetables into the casserole.
What to Serve With
A crisp green salad makes a refreshing side for this rich casserole. The fresh vegetables and light dressing provide a nice contrast to the creamy potatoes and beef.
Steamed green beans, roasted broccoli, or glazed carrots also pair beautifully with this hearty main dish.
For an especially comforting meal, serve the casserole with warm dinner rolls or crusty bread.
Make-Ahead Instructions
This casserole can be prepared in advance for easier meal planning.
You can cook the beef mixture and prepare the cheese sauce ahead of time. Store them separately in covered containers in the refrigerator.
The potatoes are best sliced shortly before assembling the casserole to maintain their texture and appearance.
If assembling the complete casserole ahead of time, cover it tightly and refrigerate. Allow the chilled casserole to sit at room temperature briefly before baking, and expect the baking time to be slightly longer because the ingredients start cold.
Storage
Allow leftover casserole to cool before transferring it to an airtight container.
Refrigerate for up to 3–4 days.
Keep the casserole refrigerated whenever it is not being served.
Reheating
Individual portions can be reheated in the microwave until hot throughout.
For larger portions, place the casserole in an oven-safe dish, cover with foil, and reheat at 350°F (175°C) until warmed through.
Adding a small splash of milk before reheating can help restore some of the sauce’s creamy consistency.
Freezing
This casserole can be frozen, although the potatoes may become slightly softer after thawing.
Allow the casserole to cool completely before transferring portions to freezer-safe containers.
Freeze for up to 2 months for best quality.
Thaw overnight in the refrigerator before reheating.
Common Mistakes to Avoid
Slicing the Potatoes Too Thick
Thick potato slices may remain firm while the cheese sauce becomes overly cooked. Keep the slices around 1/4 inch thick for more consistent results.
Making the Cheese Sauce Too Thin
Allow the milk and cream mixture to simmer until it has thickened before adding the cheese. A sauce that is too thin can make the finished casserole watery.
Adding Cold Cheese
Cheese melts more smoothly when incorporated into a hot sauce. Add the shredded cheddar after removing the sauce from the heat and stir until completely melted.
Skipping the Foil
The covered baking stage helps create the steam needed to cook the potato layers. Removing the foil too early can result in undercooked potatoes.
Cutting the Casserole Immediately
Let the finished casserole rest for several minutes before serving. This gives the sauce time to settle and makes portions easier to scoop.
