Sliced Kielbasa: Look for quality smoked kielbasa with a firm texture and rich flavor – it’s the star protein here.
Frozen Pierogies: These save so much time and have a tender potato and cheese filling that pairs perfectly with kielbasa.
Cream Cheese: Softened to creamy perfection, it adds richness and helps thicken the sauce.
Sour Cream: Adds a bit of tang and silky smoothness to the sauce.
Chicken Broth: Keeps the sauce pourable and infuses subtle savory depth.
Onion & Garlic Powder: These spices enhance the flavor without overpowering the dish.
Salt & Pepper: Essential for balancing and bringing out the natural flavors.
Cheddar & Mozzarella Cheese: A duo for melty, gooey, bubbly topping – cheddar brings sharpness, mozzarella adds that stretch.
Sliced Green Onions: Fresh garnish that adds a mild onion crunch and pops of color.

Make It Your Way

One of the best things about this baked kielbasa pierogi casserole recipe is how you can tweak it to suit your mood or pantry. I love adding a little heat or swapping cheeses depending on what I have on hand.

Add Some Heat: I sometimes mix in diced jalapeño or a pinch of red pepper flakes to give it a nice spicy kick that contrasts the creamy sauce.
Cheese Swaps: Feel free to experiment with pepper jack for spice or smoked gouda for a different smoky vibe; the casserole still bakes beautifully.
Vegetable Boost: Sometimes adding sautéed onions, mushrooms, or bell peppers adds nice texture and flavor complexity.
Make it Lighter: You can substitute Greek yogurt for sour cream to lighten the sauce without losing tang.

Step-by-Step: How I Make Baked Kielbasa Pierogi Casserole Recipe

Step 1: Assemble the Base Ingredients

Start by preheating your oven to 375°F – this temp is perfect to cook everything evenly without drying it out. Then, spray your 9×13-inch baking dish with non-stick spray so nothing sticks (trust me, it helps for easy cleanup). Layer the sliced kielbasa and frozen pierogies evenly on the bottom. I like to spread them out a bit to avoid clumping, which helps them bake through evenly.

Step 2: Whisk the Creamy Sauce

In a bowl, soften up the cream cheese first so it blends smoothly. I usually let it sit at room temp or zap it in the microwave for 15 seconds. Then, mix it with sour cream until you get a silky texture. Slowly pour in the chicken broth and fold in your seasonings – onion powder, garlic powder, salt, pepper – and half the cheddar and mozzarella cheeses. Whisk it all till it’s uniform; this sauce will soak nicely into the pierogies and kielbasa.

Step 3: Combine and Bake

Pour the creamy sauce over the pierogies and kielbasa in the baking dish. Use a spoon or spatula to gently toss and coat everything evenly – don’t worry if some sauce pools at the bottom, it’ll absorb while baking. Then sprinkle the rest of your shredded cheddar and mozzarella on top for that irresistible gooey, golden crust. Cover the dish tightly with foil – this traps steam to cook the pierogies through. Bake covered for 30 minutes.

Step 4: Finish and Garnish

After 30 minutes, take off the foil and bake for an additional 10 minutes so the cheese browns and bubbles beautifully. Once out of the oven, let it cool for a few minutes – this helps the sauce thicken up slightly so it’s not too runny. Sprinkle sliced green onions on top for a fresh, bright finish that cuts through the richness.

Top Tip

From my kitchen to yours, I’ve learned a few things that make this Baked Kielbasa Pierogi Casserole Recipe come out consistently fantastic every time.

Room Temperature Dairy: Softening the cream cheese and sour cream before mixing helps your sauce come out super smooth without lumps.
Even Layering: Spreading out pierogies and sausage helps heat circulate so everything cooks evenly — don’t overcrowd your dish!
Foil Covering: Baking covered retains moisture so your pierogies don’t dry out; removing foil at the end ensures a bubbly, golden top.
Rest Before Serving: Give the casserole a few minutes after baking to firm up the sauce and make serving cleaner and easier.

How to Serve Baked Kielbasa Pierogi Casserole Recipe

Kielbasa Pierogi Casserole - Serving Suggestion

Garnishes

I always top this casserole with fresh sliced green onions – the mild onion flavor and crunch add the perfect finishing touch. Sometimes I add a dollop of sour cream on the side for extra creaminess and a little fresh parsley for color.

Side Dishes

This casserole is so filling, but a crisp green salad with a bright vinaigrette balances the richness beautifully. Roasted or steamed veggies, like asparagus or green beans, also pair wonderfully for a complete meal.

Creative Ways to Present

For special occasions, I like to bake individual portions in small ramekins topped with fresh herbs and a sprinkle of paprika for color. It makes the dish feel a little fancy but keeps that comforting, homey vibe.

Make Ahead and Storage

Storing Leftovers

I usually store leftover baked kielbasa pierogi casserole in an airtight container in the fridge for up to 3 days. Before reheating, it’s best to let it come to room temperature so it heats evenly.

Freezing

This casserole freezes well! Just bake it as usual, cool completely, then cover tightly with foil and plastic wrap before freezing. When you want to enjoy it again, thaw overnight in the fridge and reheat gently in the oven.

Reheating

I find reheating in the oven at 350°F keeps the cheese bubbly and doesn’t dry the pierogies out like microwaving can. Cover loosely with foil for the first 10 minutes to retain moisture, then remove foil to crisp the top again.

Frequently Asked Questions:

Can I use fresh pierogies instead of frozen?

Absolutely! If you have fresh pierogies, you can use them – just reduce the covered baking time by about 5 to 10 minutes since fresh ones cook faster than frozen.

Can I prepare this casserole ahead of time?

Yes! You can assemble the casserole up to a day before baking. Just cover it tightly and keep it refrigerated, then bake it fresh when you’re ready.

What sauces or dips pair well with this casserole?

A dollop of sour cream is classic and complements the richness perfectly. You could also serve it with a tangy mustard sauce or a mild horseradish cream for a little zing.

Is it possible to make this dish vegetarian?

You can make a vegetarian version by swapping kielbasa for smoked or seasoned mushrooms, or a plant-based sausage alternative. Just adjust seasoning accordingly for the best flavor.
