Oven-Baked Pierogi Kielbasa Casserole

Introduction

Oven-Baked Pierogi Kielbasa Casserole is a warm, hearty comfort dish that combines soft potato-and-cheese pierogi with smoky kielbasa sausage in a creamy, cheesy sauce. It is simple to prepare, family-friendly, and perfect for busy weeknights or cozy weekend dinners. Baking everything together allows the flavors to blend beautifully while creating a golden, bubbling top layer.

Ingredients

• 1 package frozen potato and cheese pierogi
• 14 oz kielbasa sausage, sliced into rounds
• 1 small onion, sliced
• 1½ cups shredded cheddar cheese
• 1 can cream of mushroom soup
• ¾ cup sour cream
• ½ cup milk
• 1 tablespoon butter
• Salt and black pepper, to taste
• Optional: chopped parsley or green onions for garnish

Instructions

1. Preheat the oven
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Cook the sausage and onion
   In a skillet over medium heat, melt the butter. Add the sliced kielbasa and onion. Cook for 5–7 minutes until lightly browned and fragrant.
3. Prepare the sauce
   In a bowl, mix together the cream of mushroom soup, sour cream, milk, and a pinch of black pepper until smooth.
4. Assemble the casserole
   Spread the frozen pierogi evenly in the baking dish. Add the cooked kielbasa and onions over the top. Pour the sauce mixture evenly over everything.
5. Add cheese
   Sprinkle the shredded cheddar cheese across the casserole.
6. Bake
   Cover with foil and bake for 30 minutes. Remove the foil and bake an additional 10–15 minutes until hot, bubbly, and lightly golden on top.
7. Serve
   Let the casserole rest for 5 minutes before serving. Garnish with parsley or green onions if desired.

Description

This casserole is creamy, cheesy, smoky, and incredibly satisfying. The pierogi become tender while soaking up the rich sauce, and the kielbasa adds a savory depth that balances the creamy texture perfectly. It is a complete meal in one dish and pairs wonderfully with a crisp green salad or steamed vegetables.

Tips

• Brown the kielbasa well for extra flavor.
• Add sautéed mushrooms or bell peppers for more texture and color.
• Use sharp cheddar cheese for a richer taste.
• If you like a crispier top, broil the casserole for 2–3 minutes at the end.
• Thawing the pierogi slightly before baking can help them cook more evenly.
• For extra creaminess, stir a little cream cheese into the sauce mixture.

Correction

Here are a few improvements that make this recipe even better:

• Adding milk prevents the sauce from becoming too thick while baking.
• Covering the casserole during the first part of baking keeps the pierogi soft and moist.
• Resting the casserole before serving helps the sauce thicken slightly for cleaner portions.
• Season lightly with salt since kielbasa and cheese already contain plenty of seasoning.
