If you are looking for a hearty, comforting, and incredibly flavorful casserole that brings together the best of Eastern European flavors, this Cheesy Pierogi Bake is exactly what you need. It features tender potato pierogi, savory corned beef, and tangy sauerkraut layered under a rich, creamy sauce and topped with a golden, bubbly cheese crust. It is the perfect family dinner for a chilly evening or a cozy weekend gathering.
The magic of this recipe lies in the layers of flavor. The pierogi provide a soft, pillowy base, while the corned beef and sauerkraut add a hearty, savory depth. The creamy sauce, flavored with Dijon mustard and garlic, ties everything together, and the Swiss and cheddar cheeses melt into a gooey, golden topping.
Why This Recipe Works
This recipe relies on the classic combination of potato, beef, and sauerkraut. The pierogi are boiled briefly before baking to ensure they are tender and fully cooked. The homemade cream sauce, thickened with a roux and enriched with sour cream, creates a velvety, luxurious base. Baking the casserole until bubbling and golden allows all the flavors to meld together beautifully.
Ingredients
For the Casserole
- 24 frozen potato pierogi
- 2 cups chopped cooked corned beef
- 2 cups sauerkraut, well drained
- 1 large onion, thinly sliced
- 3 tablespoons butter
- 1 teaspoon caraway seeds, optional
- 1 1/2 cups shredded Swiss cheese

For the Sauce
- 3 tablespoons butter
- 3 tablespoons flour
- 1 cup whole milk
- 1 cup reserved pierogi cooking water
- 1/2 cup sour cream

- 1/4 teaspoon white pepper
- Salt to taste
Instructions
- Preheat oven. Butter a 9×13-inch baking dish.
- Boil pierogi for about 3 minutes, until floating. Reserve cooking water; drain.

- For sauce, melt butter in a saucepan. Whisk in flour; cook 1 minute. Gradually whisk in milk and reserved water. Simmer until thickened, then stir in remaining sauce ingredients.

Tips for the Best Results
Drain the sauerkraut well. Excess moisture can make the casserole watery. Squeeze the sauerkraut in a clean kitchen towel to remove as much liquid as possible.
Reserve the pierogi water. The starchy cooking water adds flavor and helps thicken the sauce. If you forget to reserve it, you can use additional milk instead.
Watch the bake time. Ovens vary, so start checking at 25 minutes. You want the casserole hot and bubbling and the cheese golden and melted.
Let it rest. The 10-minute resting time after baking allows the sauce to thicken and the casserole to set up slightly, making it easier to serve.
Add a little flair. A sprinkle of fresh chopped parsley or a dollop of extra sour cream on top before serving are both delicious additions.
Storage and Serving
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven until warmed through. Serve it with a simple green salad or a slice of crusty bread for a complete meal.
Hearty, cheesy, and completely irresistible, this Cheesy Pierogi Bake is a fantastic recipe to keep in your rotation for easy, comforting dinners.
