The frozen pierogies are the heart of this casserole. Choose a potato and cheese filling for the most classic taste.

Smoked sausage brings deep, savory flavor. Slice it into coins for easy layering and bite-sized pieces in every forkful.

Yellow onion, sauteed until soft, adds sweetness and a touch of sharpness that balances the richness.

Cream cheese and sour cream combine for a luscious sauce that holds the dish together and keeps it creamy.

Shredded cheddar cheese brings melty goodness and that signature cheesy crust on top.

A bit of butter, garlic powder, and simple salt and pepper round out the flavors perfectly.

How To Make the Easy Pierogi Casserole with Sausage

Step 1: Prep the Oven and Pan

Preheat your oven to 375°F. Grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Cook the Sausage and Onion

In a skillet over medium heat, cook the sliced sausage and diced onion until browned and tender. Set aside.

Step 3: Make the Creamy Sauce

In a saucepan over low heat, melt butter, then stir in cream cheese, sour cream, garlic powder, salt, and pepper. Whisk until smooth and warmed through.

Step 4: Assemble the Casserole

Layer half the frozen pierogies in the baking dish. Top with half the sausage-onion mix and half the sauce. Repeat with the remaining pierogies, sausage mix, and sauce. Sprinkle shredded cheddar cheese on top.

Step 5: Bake and Serve

Cover with foil and bake for 20 minutes. Remove the foil and bake an additional 15 minutes, until the cheese is golden and bubbly. Let rest a few minutes before serving.

How to Serve and Store This Casserole

This dish is rich, hearty, and filling—a full meal in itself. It serves 6 to 8 people easily, especially with a simple side or salad. You can store leftovers in an airtight container in the fridge for up to 4 days. To reheat, just pop a portion in the microwave or warm in a 350°F oven until heated through.

It also freezes surprisingly well. Just let the baked casserole cool completely, then wrap tightly and freeze for up to 2 months. Reheat from frozen or thaw overnight for quicker baking.
