1 (16 oz) package frozen potato and cheese pierogies
12 oz kielbasa sausage, sliced into rounds
1 tbsp olive oil
1 small onion, diced
2 cups shredded cheddar cheese
1 cup shredded mozzarella cheese
1 cup heavy cream

Salt and black pepper to taste
1 tbsp fresh parsley, chopped

Directions

1. Preheat oven to 375°F (190°C) and grease a baking dish.
2. Heat olive oil in a skillet over medium heat. Sauté kielbasa slices until browned, about 3–4 minutes per side. Remove and set aside.
3. In the same skillet, cook onions until softened and lightly caramelized.
4. In a saucepan, combine heavy cream, chicken broth, cheddar cheese, mozzarella cheese, garlic powder, salt, and pepper. Stir over low heat until the cheese is melted and the sauce is smooth.
5. Arrange pierogies in the prepared baking dish. Top with kielbasa and onions, then pour the cheese sauce evenly over the top.
6. Bake uncovered for 20–25 minutes, until bubbly and golden on top.
7. Garnish with fresh parsley before serving.

Storage/reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for about 15 minutes, or until heated through. For quicker reheating, use the microwave, though the texture will be slightly softer.

FAQs

Can I use fresh pierogies instead of frozen?

Yes, but reduce the baking time slightly since fresh pierogies cook faster.

Do I need to boil frozen pierogies before baking?

No, they will cook fully in the oven when baked in the sauce.

Can I make this dish ahead of time?

Yes, assemble it up to 24 hours in advance, cover, refrigerate, and bake when ready to serve.

What type of kielbasa works best?

Smoked pork kielbasa is traditional, but beef or turkey kielbasa also work well.

Can I freeze leftovers?

Yes, but the sauce may separate slightly when reheated. For best results, freeze in individual portions and reheat in the oven.

Can I make this without meat?

Absolutely — just omit the kielbasa or replace it with sautéed vegetables.

How do I prevent the cheese sauce from becoming grainy?

Cook over low heat and avoid boiling once the cheese is added.

Can I use milk instead of heavy cream?

Yes, but the sauce will be thinner. You may need to thicken it with a bit of flour or cornstarch.

What sides go well with this bake?

A crisp green salad, steamed vegetables, or roasted Brussels sprouts pair well.

Can I make this spicier?

Add red pepper flakes or use spicy kielbasa for a little heat.
