My Pierogi, Cabbage & Kielbasa Casserole with Cheddar Cheese might just be the most Polish casserole ever. It’s loaded with tender pierogies, buttery cabbage, smoky kielbasa, and a creamy cheddar sauce for the ultimate comfort food dinner.

The Most Polish Casserole Ever (Pierogies, Cabbage & Kielbasa)
If there was ever a casserole that felt like pure comfort food heritage, this might be it. My casserole is buttery cabbage, tender pierogies, smoky kielbasa, and a creamy cheddar sauce all baked together into what I can only call the most Polish casserole ever. It’s hearty, cozy, and the kind of dinner that makes everyone go quiet for a second bite.
And honestly, I think I’ve fully accepted that I’m just on a pierogi-and-cabbage kick lately. I’ve always loved that combination, especially in my Pierogies With Cabbage recipe, so turning it into a full baked casserole with kielbasa just felt right. This is the kind of comfort food I make when I want something filling, nostalgic, and a little bit extra in the best way.
Recipe Tips + Helpful Notes
- Cabbage — Use a small head of green cabbage, coarsely chopped. It looks like a lot at first, but it cooks down beautifully.
- Butter — I know 2 tablespoons doesn’t look like enough, but you’ve got to trust your girl on this one. The cabbage releases plenty of liquid as it cooks, and it all turns into that perfect saucy base.
- Pierogies — I use 2 packages of frozen mini pierogies (Ms. T’s is my go-to). Take them out at the very beginning when you start chopping the cabbage so they can thaw naturally while you cook everything else.
- Kielbasa — Slice it thin, then cut each slice in half so you get nice bite-sized pieces throughout the casserole.
Let’s Make My Pierogi Casserole!

Add in some seasonings!
Add in the cream sauce ingredients and some cheese and cook until nice and creamy. Throw it in the casserole dish!
Add in the pierogies and kielbasa.
Cover with foil and cook. Then sprinkle a little more cheese on top…
And bake until bubbly golden and well, perfect!
Serve and enjoy this delicious casserole!
Seriously, there’s leftovers?
Store leftovers covered in the fridge for up to 4 days. This casserole reheats really well the next day.
To reheat, warm individual portions in the microwave or reheat covered in the oven until hot. Add a splash of milk if needed to loosen the sauce back up and keep it creamy.

Pierogi, Cabbage and Kielbasa Casserole
PrintIngredients
- 2 tablespoons butter
- 1 small head cabbage coarsely chopped
- 1 small yellow onion finely chopped
- 2 cloves garlic minced
- 1/2 teaspoon salt
- 1/2 teaspoon paprika
- 1/4 teaspoon dried thyme
- 1 cup milk
- 1/2 cup chicken broth
- 1 tablespoon all-purpose flour
- 1/2 teaspoon onion powder
- 1/2 teaspoon black pepper
- (2) 12 ounce packages frozen mini pierogies, thawed
- 12 ounces cooked kielbasa sliced thin and halved
- 2 cups shredded cheddar cheese divided
Instructions
- Preheat oven to 350 degrees F. Lightly spray a 9×13-inch baking dish with nonstick spray. Let the boxes of mini pierogies sit at room temperature while you prepare the casserole so they can thaw slightly.
- In a large skillet, melt butter over medium heat. Add cabbage and onion and cook, stirring occasionally, until softened and lightly golden, about 10-15 minutes.
- Stir in garlic, salt, paprika, and thyme and cook for 1 minute until everything smells really good.
- In a small bowl whisk together milk, chicken broth, flour, onion powder and black pepper until smooth. Pour the gravy mixture into the skillet with the cabbage. Stir and cook for a few minutes until slightly thickened and creamy. Stir in 1 cup of the shredded cheddar cheese until melted into the sauce.
- Pour cabbage mixture into the baking dish. Gently fold in pierogies and kielbasa until everything is evenly coated.
- Cover with foil and bake for 25 minutes.
- Remove foil, sprinkle remaining cheddar cheese over the top, and bake uncovered for 10 more minutes, until melted and bubbly.
- Let rest for a few minutes before serving. Enjoy dinner!
