What Is A Pierogi?
A pierogi is a popular Polish dumpling that’s made with unleavened dough and a savory filling. These boiled or fried dumplings can be made with potatoes, sauerkraut, cabbage, and various other fillings. This hearty family dinner recreates the flavor of a fresh potato pierogi in the form of a cheesy casserole!
Pierogi Casserole Ingredients
Simple, easy to find ingredients are all you need to make this casserole. Yes, I know, noodles + potatoes = carbs on carbs! But let me tell you it is WORTH IT.
- Diced Onion
- Kosher Salt
- Lasagna Noodles
- Cottage Cheese: I use small curd, 4% cottage cheese in my casserole.
- Mashed Potatoes
- Black Pepper
- Onion Powder
- Grated Cheddar Cheese
- Fresh Parsley: If desired, garnish your pierogi casserole with a sprinkle of chopped parsley.
This casserole really is layer upon layer of cozy flavor. Here’s how to make it:
- Prepare for Baking: Preheat the oven to 350°F. Coat a 9×13-inch baking dish with nonstick spray. Set aside.
- Cook Onions: Heat the butter in a skillet over medium heat. Add the diced onions into the melted butter and season with 1/2 teaspoon of kosher salt. Cook the onions until they are soft and caramelized, stirring frequently. Remove from the heat and set aside.
- Cook Noodles: Bring a large pot of water to a boil and cook the lasagna noodles according to the package directions. Drain.
- Make Filling: While the noodles are cooking, combine the cottage cheese, mashed potatoes, egg, pepper, onion powder, 1 cup of grated cheese, remaining 1 teaspoon kosher salt, and HALF of the onions. Stir to combine.
- Assemble Casserole: Place 3 noodles into the bottom of the prepared dish. Top with half of the cottage cheese mixture and spread to cover the noodles. Lay 3 more noodles on top of the filling and top that with the remaining filling mixture. Lay the last 3 noodles on top, sprinkle with the reserved onions and remaining 1/2 cup of cheese.
- Bake: Cover the pan with foil and bake for 30 minutes. Remove the foil and broil for 3 minutes.
- Let Cool & Serve: Allow the casserole to cool for 15-20 minutes. Sprinkle with parsley, if desired, and serve!
Tips For This Lasagna-Style Casserole:
- Add TINY amount of Olive Oil to Noodles: To prevent your lasagna noodles from sticking together, toss them with a small drizzle of olive oil after you drain them and stir to coat. You don’t want to add too much, as the starch on the noodles helps hold it all together, but a small amount will save you from them sticking together!
- Use Homemade Mashed Potatoes: You can buy pre-made mashed potatoes at the grocery store, but this recipe is a great way to use up leftovers. Try my easy Crockpot Mashed Potatoes!
- Cool Before Serving: Let your casserole cool for at least 15 minutes before you serve it. This will help you get those pretty slices!
- Add Bacon: Top your casserole with crumbled bacon to add a crispy, savory crunch.
- Mix up the Flavors: Feel free to change up the seasonings in this casserole to give it different flavors. Try using garlic powder or another kind of cheese!
- Add Chicken: This casserole would taste great with cubed or shredded chicken on top.
- Add Sausage: For another hearty add-in idea, top your pierogi casserole with slices of smoked sausage.
What Goes with Pierogi Casserole
- Salad: I love pairing this casserole with a simple tomato or cucumber salad! It’ll go great with pretty much any salad you can think of.
- Sour Cream: Sour cream is a tasty dip to serve with this pierogi casserole.
- Apple Cider: For the ultumate fall dinner, pair your casserole with a helping of hot or cold apple cider!
How to Store and Reheat Leftovers
Store leftovers in an airtight container in the fridge for up to 3 days. You can also make this casserole ahead of time and freeze it before baking, if desired. Store it airtight in the freezer and thaw it in the fridge overnight before you plan to serve it.
You can reheat your leftover casserole in the oven or the microwave. If you’re reheating individual servings, microwave them in 10 second intervals until warm. To reheat your casserole in the oven, cook it at 350°F for 10-15 minutes, or until the cheese starts bubbling.
