4 medium russet or Yukon Gold potatoes (about 2 lbs), thinly sliced (⅛-inch thick)
2 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
½ teaspoon paprika (optional)
For the Meat Layer:
1½ lbs ground beef (85/15 or 90/10 works well)
1 medium yellow onion, finely diced
2 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried thyme (or 1 tablespoon fresh)
1 teaspoon Worcestershire sauce
2 tablespoons tomato paste (optional, adds depth)
½ cup beef broth
For the Cheese Layer:
2 cups shredded cheddar cheese (or a mix of cheddar and mozzarella)
½ cup grated Parmesan cheese
For Garnish:
Fresh parsley or chives, chopped
The Method: Layer, Bake, Devour
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish or similar-sized casserole dish.
Step 2: Prepare the Potatoes
Scrub potatoes thoroughly (peeling is optional). Slice into ⅛-inch thick rounds. A mandoline makes this quick and ensures uniform thickness.
In a large bowl, toss potato slices with olive oil, salt, pepper, garlic powder, and paprika until evenly coated. Set aside.
Step 3: Cook the Meat Layer
In a large skillet over medium-high heat, cook ground beef until browned, breaking it into crumbles, 6-8 minutes.
Add onion and cook until softened, 4-5 minutes.
Add garlic and cook until fragrant, about 1 minute.
Drain excess grease if needed.
Stir in salt, pepper, thyme, Worcestershire sauce, tomato paste (if using), and beef broth. Simmer for 2-3 minutes until slightly thickened. Remove from heat.
Step 4: Assemble the Casserole
Arrange half the potato slices in an even layer in the prepared dish, slightly overlapping.
Spread half the meat mixture evenly over the potatoes.
Sprinkle 1 cup shredded cheese over the meat.
Repeat layers: remaining potatoes, remaining meat mixture.
Top with remaining 1 cup shredded cheese and Parmesan.
Step 5: Cover and Bake
Cover tightly with foil and bake for 45 minutes.
Remove foil and bake for another 15-20 minutes, until potatoes are tender when pierced with a fork and the top is golden and bubbly.
Step 6: Rest and Serve
Let the casserole rest for 10-15 minutes before serving. This allows the layers to set and makes serving much cleaner.
Garnish with fresh parsley or chives.
Pro-Tips for Casserole Perfection
1. Slice Potatoes Uniformly
A mandoline is worth the effort. Slices of uneven thickness mean some potatoes will be undercooked while others turn to mush.
2. Don't Skip the Resting Period
Those 10-15 minutes after baking are crucial. A hot casserole fresh from the oven is a delicious mess. After resting, it becomes a beautiful, sliceable masterpiece.
3. Test Potato Doneness
Pierce the center with a knife—it should slide through with minimal resistance. If potatoes are still firm, re-cover and bake 10-15 minutes more.
4. Drain the Meat Well
If your ground beef releases a lot of fat, drain it before adding broth and seasonings. Too much grease can make the casserole heavy.
5. Grate Your Own Cheese
Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grating your own takes 2 minutes and makes a noticeable difference.
6. Make It Your Own
See variations below—this recipe is endlessly adaptable.

Your Casserole Questions, Answered
Can I use sweet potatoes?
Yes! Sweet potatoes work beautifully. They may cook slightly faster, so check for doneness at 60 minutes.
Do I need to peel the potatoes?
Not for this recipe. The skins add texture, nutrients, and help the layers hold together. Just scrub them well.
My potatoes are still hard after baking. What went wrong?
Likely sliced too thick or underbaked. Next time, slice thinner and/or bake longer. You can also parboil potato slices for 3-4 minutes before assembling.
Can I make this dairy-free?
Use dairy-free cheese alternatives and ensure your Worcestershire sauce is dairy-free. The texture will be slightly different but still delicious.
Can I add other vegetables?
Absolutely! Mushrooms, zucchini, spinach, and carrots all work well. Sauté harder vegetables before adding to remove excess moisture.
Can I use ground turkey or chicken?
Yes. Add a tablespoon of olive oil to the pan since they're leaner than beef.
