Kielbasa sausage: Adds a smoky, meaty punch and a little spice that pairs wonderfully with creamy textures.
Frozen pierogies: These are the star carbohydrate — starchy, soft, and filling. Using them frozen keeps things easy and saves prep time.
Cream cheese: Gives the sauce a rich creaminess and helps bind everything together silky smooth.
Sour cream: Adds a subtle tang that cuts through the richness and keeps the flavors bright.
Chicken broth: Lightens the sauce just enough so it’s creamy but not heavy or gluey.
Onion powder & garlic powder: Simple, pantry staples that deepen the savory flavor without overpowering.
Salt & pepper: Essential to balance and enhance all the ingredients’ tastes.
Shredded cheddar and mozzarella cheese: A duo that brings gooey meltiness and sharp bite — the cheddar adds punch and mozzarella the stretch.
Green onions: Fresh garnish that adds color and a bit of crunch, lifting the casserole with freshness.

Make It Your Way

I often tweak this recipe based on what I have on hand or who I'm cooking for. It’s super adaptable, so feel free to make it your own. You can switch up the cheese or add veggies for extra color and nutrition.

Variation: One of my favorite tweaks is stirring in sautéed mushrooms or caramelized onions into the sauce before baking — it adds surprisingly wonderful depth.
Dietary switch: For a lighter version, swap out half the cream cheese for Greek yogurt and use reduced-fat cheese, but keep the flavor balance in mind.
Spicy kick: Toss in a pinch of smoked paprika or cayenne if you like a little heat that complements the kielbasa.
Extra veggies: Frozen peas or chopped bell peppers mixed with the pierogies make this meal even more colorful and satisfying.

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

Step 1: Prep the Base with Kielbasa and Pierogies

Start by preheating your oven to 375°F and greasing a 9×13-inch baking dish with non-stick spray — trust me, it’s one less sticky mess to worry about. Lay down the sliced kielbasa and frozen pierogies right into the baking dish, spreading them out evenly. Skipping the extra boiling means less fuss, and the oven will do the work to warm and cook everything perfectly.

Step 2: Whisk Up the Creamy Sauce

Grab a bowl and use a hand mixer or whisk to blend the softened cream cheese and sour cream until smooth — no lumps allowed! Add in chicken broth, onion powder, garlic powder, salt, pepper, and half of both cheddar and mozzarella cheeses. Whisk thoroughly until you have a creamy, velvety sauce that’s bursting with flavor.

Step 3: Combine and Bake

Pour the creamy sauce over your kielbasa and pierogies, then stir gently to coat everything without smashing the pierogies. Sprinkle the remaining cheddar and mozzarella cheese evenly over the top. Cover the dish tightly with foil to keep moisture in, and bake for 30 minutes. Then, remove the foil and bake for another 10 minutes so you get a bubbly, golden cheesy crust that’s oh-so-tempting.

Step 4: Rest, Garnish, and Serve

After pulling the casserole from the oven, let it sit for about 5 minutes so it can set up a bit and cool down—this also helps the sauce thicken slightly. Then, top with a handful of freshly sliced green onions for a fresh crunch and a pop of color before serving.

Top Tip

Making this Baked Kielbasa Pierogi Casserole Recipe for the first time, I learned several tricks that really improved the outcome — and I want you to have the same success right away!

Don’t skip the foil cover: It traps steam and melts the cheese gently without drying out the pierogies.
Use room-temperature cream cheese: It mixes easier, giving you a smoother sauce without lumps.
Even slices of kielbasa: About ¼-inch thick pieces cook evenly and distribute flavor throughout the casserole.
Let it rest: Cutting in too soon means the sauce will run all over the place — patience pays off with perfect plated servings.

How to Serve Baked Kielbasa Pierogi Casserole Recipe

Garnishes

I always go with freshly sliced green onions because their mild sharpness contrasts beautifully with the rich casserole. Some days, I add a dollop of sour cream on the side for extra creaminess and tang — it’s a game-changer!

Side Dishes

This casserole is pretty filling on its own, but I like pairing it with a crisp side salad dressed with a light vinaigrette or some steamed green beans for a fresh burst. Roasted Brussels sprouts or a simple cucumber salad also balance the richness perfectly.

Creative Ways to Present

For the holidays or special dinners, I’ve served this casserole in individual ramekins topped with a sprinkle of fresh herbs like parsley or chives — it feels special and keeps portions tidy. You could even add some crispy bacon bits on top for a fun twist!

Make Ahead and Storage

Storing Leftovers

Leftovers store wonderfully in an airtight container in the fridge for up to 3 days. When I reheat, I usually use the oven or toaster oven to keep that delicious crust crispy rather than soggy.

Freezing

I’ve frozen this casserole both before and after baking. When freezing before baking, cover tightly with foil and plastic wrap. Bake from frozen, adding extra time. For baked leftovers, let cool completely, then freeze in portions. It thaws and reheats nicely without losing flavor or texture.

Reheating

To keep that cheesy topping beautiful, I reheat leftovers in a 350°F oven for about 15-20 minutes, uncovered. Avoid microwaving unless you’re in a rush, as it can make the pierogies a bit rubbery.

Frequently Asked Questions:

Can I use fresh pierogies instead of frozen in the Baked Kielbasa Pierogi Casserole Recipe?

You certainly can! Fresh pierogies may cook faster, so I recommend reducing the initial covered baking time by about 5-10 minutes to avoid overcooking. Keep an eye on the golden cheese topping.

What type of kielbasa should I buy?

I prefer smoked kielbasa for this recipe because the smokiness adds depth, but feel free to use mild or spicy kielbasa based on your flavor preference. Just slice it evenly for best results.

Can I make this dish gluten-free?

Absolutely! Use gluten-free pierogies (which some specialty stores offer) or even swap in gluten-free gnocchi for a similar starchy base. Just be sure to check other ingredients for gluten content.

Is this recipe freezer-friendly?

Yes, this casserole freezes very well both before and after baking. Be sure to cool it completely if freezing baked leftovers. When baking from frozen, add 10-15 extra minutes to cooking time and cover with foil to retain moisture.

Final Thoughts

This Baked Kielbasa Pierogi Casserole Recipe is a go-to for me when I want a meal that’s both satisfying and surprisingly simple to pull together. It never fails to impress friends and family alike, delivering that perfect mix of creamy, cheesy, and savory flavors. I hope you find it just as comforting and effortless to make as I do — probably will be a favorite in your rotation before long!
