• Forgiving & flexible: Easily adapt with different cheeses or veggies.
• Great leftovers: Flavors meld and improve overnight.
• One-pan wonder: Cook and bake in one skillet for easy cleanup.

Ingredients & Tools

• 1.5 lbs russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
• 1.5 lbs lean ground beef
• 1 large yellow onion, finely diced
• 3 cloves garlic, minced
• 1 (15 oz) can crushed tomatoes
• 1 cup beef broth
• 2 tbsp tomato paste
• 1 tbsp Worcestershire sauce
• 1.5 tsp dried oregano
• 1 tsp smoked paprika
• 2 cups shredded sharp cheddar cheese, divided
• 1/4 cup chopped fresh parsley
• To taste kosher salt and black pepper

Tools: A large, oven-safe skillet (at least 12 inches) or a Dutch oven, a mandoline (highly recommended for even potato slices), and a wooden spoon.

Notes: The quality of your ingredients really shines here. Using a good, lean ground beef means less grease to drain, and sharp cheddar provides a tangy punch that cuts through the richness beautifully.

Before You Start: Tips & Ingredient Notes

• Slice those potatoes thin and even. This is probably the most important step for success. Uneven slices will cook at different rates, leaving you with some crunchy and some mushy potatoes. A mandoline is your best friend here for perfect, paper-thin slices.
• Don’t skip the Worcestershire sauce. It might seem like a small ingredient, but it adds a deep, savory, umami richness to the beef that you’ll really miss if it’s not there. It’s the secret flavor booster.
• Use an oven-safe skillet from the start. This allows you to build your entire recipe in one pan, from browning the beef to baking the final casserole. If you don’t have one, you can transfer everything to a 9×13 inch baking dish before topping with cheese and baking.
• Let it rest before serving. I know it’s tempting to dive right in, but giving the casserole 5-10 minutes to settle after it comes out of the oven will make it much easier to slice and serve neatly.

How to Make Ground Beef and Potato Casserole

Storage & Freshness Guide

• Fridge: Cool completely, store in an airtight container for up to 4 days.
• Freezer: Wrap baked and cooled casserole tightly; freeze up to 2 months.
• Reviving: Reheat in oven at 350°F until hot; avoid microwave for best texture.

Serving Suggestions

Complementary Dishes

• A simple green salad with a tangy vinaigrette — The crisp, acidic greens cut through the richness of the casserole perfectly, balancing the whole meal.
• Garlic bread or crusty dinner rolls — You’ll want something to mop up every last bit of that savory sauce, and nothing does it better than warm, buttery bread.
• Steamed green beans with almonds — Their bright, snappy texture and nutty flavor provide a lovely contrast to the soft, cheesy layers of the main dish.

Drinks

• A robust red wine like a Zinfandel or Malbec — The berry notes and slight spice in these wines stand up beautifully to the hearty beef and tomato flavors.
• A dark lager or amber ale — The malty, caramel notes in these beers complement the savory depth of the casserole without overpowering it.
• Sparkling water with a squeeze of lemon — For a non-alcoholic option, the effervescence and citrus cleanse the palate wonderfully between bites.

Something Sweet

• Classic apple crumble with vanilla ice cream — The warm, spiced fruit and cold, creamy ice cream is a timeless and comforting way to end this hearty meal.
• Dark chocolate brownies — A rich, fudgy brownie satisfies that chocolate craving and feels like a real treat after a savory dinner.
• Lemon sorbet — Its bright, clean, and tart flavor is incredibly refreshing and acts as a perfect palate cleanser after such a substantial dish.

Top Mistakes to Avoid

• Mistake: Using potatoes that are sliced too thick. Thick slices won’t cook through in the allotted time, leaving you with unpleasantly crunchy potatoes in your finished casserole. Thin and even is the key.
• Mistake: Forgetting to use an oven-safe skillet. If you start in a regular skillet, you’ll have to transfer the hot mixture to a baking dish, which is messy and risks burning yourself. Plan ahead!
• Mistake: Skipping the rest time. I’ve messed this up before too, diving in with a spoon straight from the oven. It will be soupy and difficult to serve. Letting it rest allows the starches to set and the layers to firm up.
• Mistake: Overcrowding the beef while browning. If you add too much beef to the pan at once, it will steam instead of brown. Cook in batches if necessary to get that nice, flavorful sear.

Expert Tips

• Tip: Soak your potato slices. For an even better texture, you can soak the sliced potatoes in cold water for 20 minutes before assembling. This removes excess starch, which prevents them from getting gummy and helps them stay distinct.
• Tip: Brown the beef well. Don’t just gray it—really let it develop a deep, brown crust. Those browned bits, called fond, are packed with flavor and will dissolve into your sauce, making it incredibly rich.
• Tip: Customize your cheese blend. While cheddar is classic, try a mix! A combination of cheddar, Monterey Jack, and a little parmesan creates a more complex, gooey, and flavorful cheesy topping.
• Tip: Add a hidden veggie layer. For a sneaky nutritional boost, add a layer of thawed frozen spinach (squeezed very dry) or sautéed mushrooms between the beef and the potatoes. No one will suspect a thing!

FAQs

Can I make this Ground Beef and Potato Casserole ahead of time?
Absolutely! You can assemble the entire casserole up to the point of baking (through Step 5), cover it tightly, and refrigerate it for up to 24 hours. When you’re ready, you’ll just need to add about 10-15 minutes to the initial covered baking time since it will be going into the oven cold. It’s a fantastic make-ahead meal for busy days.

What’s the best way to store and reheat leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I strongly recommend using an oven or toaster oven at 350°F until warmed through. This will keep the texture of the potatoes and cheese much better than the microwave, which can make them a bit rubbery. If you must use a microwave, do it in short bursts with a cover to trap steam.

Can I use a different type of potato?
You can, but the results will vary. Russets are ideal because they are starchy and break down a little, helping to thicken the sauce and giving a fluffy texture. Yukon Golds will work and are waxier, holding their shape better but resulting in a less cohesive dish. I’d avoid red potatoes as they can become too waxy and firm for this application.

My casserole is too watery. What happened?
This usually happens for one of two reasons: the potatoes weren’t sliced thinly enough, so they didn’t absorb enough liquid, or the casserole wasn’t allowed to rest before serving. The resting time is crucial for the starches to fully absorb the surrounding liquid. Also, make sure you’re simmering the beef sauce until it’s nicely thickened before adding the potatoes.

Is it possible to freeze this casserole?
Yes, but with a caveat. The texture of the potatoes can become a little grainy upon thawing and reheating. For best results, assemble and bake the casserole completely, let it cool entirely, then wrap it tightly and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating, covered, in a 350°F oven until hot all the way through.
