Instructions to Make Baked Kielbasa Pierogi Casserole

This baked kielbasa pierogi casserole recipe is pretty much foolproof. No need to thaw the pierogies or pre-cook the sausage—it all bakes together in creamy, cheesy perfection. You’re welcome.

Preheat and Prep the Pan

Preheat oven to 375°F. Spray a 9×13-inch baking dish with nonstick spray. Trust me, you’ll want easy cleanup.

Layer Pierogies and Sausage

Toss those frozen pierogies and sliced kielbasa right into the dish. No thawing, no frying. Just vibes.

Mix the Sauce

In a mixing bowl, use a hand mixer (or some elbow grease) to blend cream cheese and sour cream until smooth. Then add chicken broth, onion powder, garlic powder, salt, pepper, and half of both the cheddar and mozzarella. Mix until smooth and luscious.

Combine and Coat

Pour that dreamy sauce over the pierogies and sausage. Gently mix everything so it’s nicely coated but not mashed.

Add That Cheese Topping

Sprinkle the remaining cheddar and mozzarella evenly on top. Don’t skimp—this is where the magic happens.

Bake Covered

Cover the dish with foil and bake for 30 minutes. Let everything get cozy and melty.

Bake Uncovered

Uncover and bake an extra 10 minutes, until that cheese on top is golden and bubbly.

Cool and Garnish

Let it sit for a few minutes before serving. Top with sliced green onions for a little zip and color.

What to Serve with Baked Kielbasa Pierogi Casserole

This dish is already a full-on comfort bomb, but if you’re looking to round out the meal, try pairing it with something fresh or crunchy. A simple green salad with vinaigrette balances the richness. Roasted veggies (think broccoli or Brussels sprouts) make a great sidekick. Even something like a tangy coleslaw or sautéed cabbage nods to its Eastern European roots. Bread? Optional—but no judgment here if you want to sop up the cheesy sauce with a hunk of crusty baguette. Hosting guests? Serve this alongside Creamy Dill Pierogi Soup for a full-on Polish-style feast.

Key Tips for Making Baked Kielbasa Pierogi Casserole

1. Don’t thaw the pierogies—they bake up perfectly from frozen and hold their shape better.
2. Use a hand mixer for the sauce. It gets everything super smooth and saves you from wrestling cream cheese with a spoon.
3. Make it spicy by tossing in crushed red pepper or a dash of smoked paprika.
4. Play with cheese—pepper jack, gouda, or Colby Jack all melt beautifully.
5. Short on sour cream? Greek yogurt totally works as a swap.
6. Want veggies? Stir in some sautéed mushrooms or caramelized onions before baking.
7. Garnish generously—green onions add freshness and a little bite.

Storage and Reheating Tips for Baked Kielbasa Pierogi Casserole

Leftovers? You lucky duck. Store them in an airtight container in the fridge for up to 3 days. To reheat, pop individual portions in the microwave for 2-3 minutes until hot, or reheat the whole thing (covered) in a 350°F oven for about 20 minutes. Pro tip: a splash of broth before reheating helps loosen the sauce. Want to freeze it? Assemble it in a foil pan but don’t bake—cover tightly and freeze. When ready, thaw overnight in the fridge and bake as usual (add about 10 minutes to the bake time).

FAQs

Can I make this ahead of time?
Absolutely. Assemble it, cover, and refrigerate up to 24 hours. Bake when you’re ready—just add 5-10 minutes extra bake time.

Can I use different pierogies?
Yep! Any flavor works, though cheddar and potato is classic. Sauerkraut pierogies? Also great if you’re into tang.

Is this dish gluten-free?
Not by default. But if you use gluten-free pierogies and double-check your kielbasa, you’re golden.

Can I add vegetables?
Totally. Mushrooms, spinach, even chopped bell peppers all work. Sauté them first so they don’t water down the sauce.
