Amish Ground Beef and Potato Casserole

This Amish-style ground beef and potato casserole is a Pennsylvania Dutch–inspired supper from the United States, made with sliced potatoes, seasoned beef, and a simple creamy sauce. Families make potato casseroles in different ways; this version layers the ingredients and bakes them until the potatoes are tender, making a filling one-dish meal.

Ingredients

2 lb russet or Yukon Gold potatoes (900 g), peeled if desired and sliced about ⅛ inch (3 mm) thick
1 lb lean ground beef (454 g)
1 medium yellow onion (about 150 g), finely chopped
2 cloves garlic (about 6 g), minced
2 tbsp unsalted butter (28 g)
2 tbsp all-purpose flour (16 g)
1 cup whole milk (240 ml)
1 cup low-sodium beef broth (240 ml)
1 tsp fine salt (5 g), divided, plus more to taste
½ tsp black pepper (1 g)
½ tsp dried thyme (about 0.5 g)
1½ cups shredded sharp cheddar cheese (170 g), divided
Chopped parsley, optional, for serving (about 2 tbsp / 8 g)

Instructions

Heat the oven and prepare the dish. Set the oven to 375°F (190°C). Grease a 9-by-13-inch (23-by-33-cm) baking dish lightly with butter or cooking spray. Peel the potatoes if you prefer a softer, more uniform texture; leaving the skins on is fine if they are clean and unblemished. Slice them evenly, about ⅛ inch (3 mm) thick. Consistent slices matter more than exact precision because pieces of very different thicknesses will finish at different times.
Brown the beef and onion. Put a large skillet over medium heat. Add the ground beef and chopped onion and cook for about 7–8 minutes, breaking the meat into small crumbles with a spoon. Stir in the garlic for the final 30 seconds. Continue cooking until the beef is no longer pink and a food thermometer inserted into several of the larger crumbles reads 160°F (71°C), the USDA FSIS safe minimum temperature for ground beef. Carefully drain excess fat, leaving a little in the pan for flavor. Set the skillet aside.
Make the creamy sauce. Melt the butter in a small saucepan over medium heat. Whisk in the flour and cook for about 1 minute, stirring so it does not brown. Gradually whisk in the milk and broth. Add ½ teaspoon of the salt, the pepper, and thyme. Cook for 3–4 minutes, whisking often, until the sauce is smooth and lightly thickened; it should coat a spoon but still pour easily. Remove it from the heat. It will thicken a little more in the oven.
Layer the casserole. Arrange about half of the potato slices in the prepared dish, overlapping them slightly. Sprinkle with a pinch of the remaining salt, then spread the cooked beef and onion evenly over the potatoes. Scatter 1 cup (115 g) of the cheddar over the beef. Add the remaining potatoes in an even layer and season with the rest of the salt. Pour the sauce slowly over the top, moving around the dish so it reaches the edges and runs between the slices. Finish with the remaining ½ cup (55 g) of cheddar.
Bake covered until the potatoes soften. Cover the dish tightly with foil and bake for 50 minutes. A tight cover traps steam and helps the potato slices cook through before the cheese browns. Keep the foil from touching the cheese where possible, or lightly grease the underside so melted cheese is less likely to stick.
Uncover and finish baking. Remove the foil and bake for another 20 minutes, until the cheese is golden in spots and a thin knife slides easily into the center potatoes. If the potatoes still feel firm, cover the dish again and bake in 10-minute increments, checking the center each time. Oven performance and potato-slice thickness can affect the timing.
Rest before serving. Let the casserole stand for 10 minutes so the sauce settles and portions hold together better. Sprinkle with parsley if you like, then scoop into bowls or onto plates. The casserole will be very hot beneath the browned cheese, so give children smaller portions and allow them to cool before eating.

Tips

Slice evenly. A sharp knife works well, or use a mandoline with its hand guard. Thin, even slices are the key to tender potatoes in the stated baking time. If your slices are closer to ¼ inch (6 mm), expect to add baking time and test the center rather than relying on the clock alone.
Choose a potato that holds its shape. Yukon Gold potatoes become creamy but generally stay intact; russets soften more and give the sauce a thicker, homier texture. Either is suitable. Avoid mixing very thick slices with very thin ones, since the thin pieces may turn mushy while the thick ones finish cooking.
Keep the sauce smooth. Add the milk and broth gradually while whisking, and do not let the flour-and-butter mixture darken. If the sauce seems too thick to pour, whisk in another tablespoon or two of milk. If it is a little lumpy, whisk firmly or strain it before pouring over the casserole.
Drain without drying the beef out. Lean beef may need little draining, while higher-fat beef can leave a greasy layer. Pour off most of the excess, but there is no need to rinse the cooked meat. Rinsing can remove flavor and makes it harder for the sauce and cheese to cling.

Serving Suggestions

Serve this casserole hot as the main dish, with a crisp green salad or a simple bowl of dressed cabbage to balance the creamy layers. Steamed green beans, buttered peas, or roasted carrots are also easy sides that can cook while the casserole is in the oven. For a traditional farmhouse-style table, add pickles or a spoonful of tangy chow-chow; the acidity provides a pleasant contrast to the rich beef and cheese.

If you are serving a larger group, cut the casserole into six generous portions or eight smaller ones and put the dish on a heat-safe trivet. A loaf of crusty bread or soft dinner rolls can help gather up the sauce. Since the casserole contains potatoes, beef, and dairy, it is substantial on its own; a lighter vegetable side is often enough.

Variations

Use a different cheese. Mild cheddar gives a familiar, creamy finish. Colby, Monterey Jack, or a mix of cheddar and Swiss can be substituted in the same quantity. Swiss adds a nuttier flavor, while a milder cheese makes the beef and thyme more prominent. Avoid using only a very strongly flavored cheese if you want the casserole to remain gentle in taste.

Add vegetables. Stir 1 cup (130 g) of thawed, drained peas or 1 cup (100 g) of sliced mushrooms into the cooked beef before layering. Mushrooms can be cooked with the onion until their liquid evaporates. If you add watery vegetables without draining them, the sauce may become thin. Finely diced carrots can also be sautéed with the onion, but give them a few extra minutes to soften.

Make it without cheese. Cheese is a convenient variation rather than a requirement for a potato-and-beef bake. Leave it out and add ½ cup (120 ml) more milk to the sauce for a softer, less rich topping. The casserole will not have a browned cheese crust, so uncover it for the final 20 minutes as directed and check that the potato edges are cooked.

Use a shortcut sauce thoughtfully. If you need to save time, a can of condensed cream-of-mushroom soup (about 10.5 oz / 298 g) mixed with ½ cup (120 ml) milk can replace the homemade sauce. It will make the dish saltier and give it a stronger mushroom flavor, so use low-sodium beef, reduce or omit the added salt, and taste the sauce before assembling. This is a convenience variation, not the same flavor as the simple milk-and-broth sauce.

Storage and Reheating

Refrigerate leftovers within 2 hours of baking. Transfer them to a shallow airtight container, or cover the baking dish once it has cooled enough to handle safely. Keep the casserole refrigerated for 3–4 days. For easier reheating, store individual portions separately; the potatoes may absorb some sauce as they sit, which is normal.

To reheat a larger portion, cover it with foil and warm it in a 350°F (175°C) oven until hot throughout, usually 20–30 minutes depending on portion size and whether it is cold from the refrigerator. Reheat individual servings in the microwave, covered loosely, in 1-minute intervals, turning or stirring where practical. Check the center with a food thermometer: USDA FSIS guidance is to reheat leftovers to 165°F (74°C). Add a tablespoon of milk or broth to a portion if it seems dry.

You can freeze the baked casserole for about 2–3 months for best quality. Cool it promptly, divide it into freezer-safe portions, and label with the date. Thaw overnight in the refrigerator before reheating; do not thaw it on the counter. The potatoes may be softer after freezing, but the flavor remains suitable for a convenient meal. Keep it refrigerated or frozen rather than storing it at room temperature.

Frequently Asked Questions

Can I assemble the casserole ahead of time?
Yes. Assemble it, cover it, and refrigerate it for up to 24 hours before baking. The potatoes may darken slightly where exposed to air, but they will still cook. Because the dish starts cold, allow extra oven time—often 10–15 minutes—and check that the potatoes are tender in the center. If the baking dish is glass, avoid moving it directly from the refrigerator into a hot oven; let it sit briefly while the oven heats, following the dish maker’s guidance.

Can I use frozen hash browns instead of sliced potatoes?
You can, but the texture and timing will change. Use about 2 lb (900 g) of thawed shredded or diced hash browns, and squeeze out excess moisture before layering. They will not form distinct potato slices, and the casserole may need less time, so begin checking for bubbling and a hot center earlier. Keep the beef at its safe cooking temperature before assembly and reheat leftovers to 165°F (74°C).

Why are the potatoes still firm after baking?
The most common causes are thick or uneven slices, a loose foil cover, or an oven that runs cool. Cover the dish again to trap steam and bake in 10-minute increments until a knife enters the center easily. If the sauce looks dry, pour a few tablespoons of milk or broth around the edges before covering. Avoid turning up the oven sharply; the top can brown before the middle cooks.

Can I prepare it without peeling the potatoes?
Yes, especially with thin-skinned Yukon Gold potatoes. Scrub them thoroughly and remove any green areas, eyes, or damaged spots before slicing. Leaving the skins on adds a slightly more rustic texture and saves preparation time. Russet skins are thicker, so peeling those is often preferable for a smoother casserole, though it is a matter of preference.

How do I know the casserole is done besides checking the time?
The top should be bubbling around the edges, and a thin knife should pass through the potato layers in the center with little resistance. Color alone is not enough: cheese can brown while thick potato slices remain firm. If you have assembled the casserole with fully cooked ground beef, use tenderness of the potatoes as the main doneness check; the initial beef-cooking step should reach 160°F (71°C) on a food thermometer.

Can I make it with ground turkey?
Yes. Substitute 1 lb (454 g) ground turkey and cook it until a thermometer reads 165°F (74°C), the USDA FSIS safe minimum for poultry. Turkey is usually leaner than beef, so you may not need to drain it. The casserole will taste milder; a little extra black pepper or thyme can add flavor without changing the method.
