Looking for a cozy, satisfying weeknight dinner that comes together in minutes but feels like comfort food at its best? This Easy Pierogi Casserole with Sausage is your answer. Creamy, cheesy, and loaded with smoky sausage and pillowy pierogies, this casserole is the kind of dish that disappears fast at the dinner table.

The pierogies bake in a creamy, cheesy sauce that hugs every bite, while the sausage adds rich, savory flavor. It’s a perfect balance of texture and taste. Whether you need something hearty after a long day or want a crowd-pleasing option for casual get-togethers, this one hits the mark.

What Kind of Pierogies Should I Use?

Frozen pierogies are the hero of this dish. You can go with classic potato and cheese, or switch it up with varieties like onion, bacon, or even jalapeño if you like a kick. No need to boil them beforehand—they cook up beautifully right in the oven.

If you prefer a homemade touch, feel free to use your own pierogi dough and filling, but the frozen kind makes this dish ultra-convenient.

Ingredients for the Easy Pierogi Casserole with Sausage

1 (16 oz) package frozen potato and cheese pierogies
1 tablespoon butter
1 small yellow onion, thinly sliced
2 cloves garlic, minced
12 oz smoked sausage, sliced into coins (kielbasa works great)
1/2 cup sour cream
1/2 cup cream cheese, softened
1/2 cup milk
1/2 teaspoon black pepper
1/2 teaspoon paprika
1 1/2 cups shredded cheddar cheese
2 tablespoons chopped green onions (for garnish)

How To Make the Easy Pierogi Casserole with Sausage

Step 1: Sauté the Onion, Garlic, and Sausage

In a large skillet, melt the butter over medium heat. Add sliced onion and cook until soft and translucent, about 5 minutes. Stir in garlic and cook for another 30 seconds. Add sausage slices and cook until lightly browned. Remove from heat.

Step 2: Make the Creamy Sauce

In a bowl, whisk together sour cream, cream cheese, milk, pepper, and paprika until smooth. This mixture should be pourable but creamy.

Step 3: Assemble the Casserole

Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Layer frozen pierogies evenly in the dish. Top with the sausage mixture, then pour the creamy sauce over everything. Sprinkle shredded cheddar cheese on top.

Step 4: Bake Until Bubbly

Cover the dish with foil and bake for 20 minutes. Remove foil and bake an additional 10-15 minutes, until the cheese is melted and the casserole is bubbling.

Step 5: Garnish and Serve

Remove from oven, let sit for 5 minutes, then top with chopped green onions. Serve warm and enjoy!

How to Serve and Store This Pierogi Casserole

This casserole is best served hot, fresh out of the oven when the cheese is melted and bubbly. Pair it with a crisp green salad or roasted veggies for a well-rounded dinner.

To store leftovers, let the casserole cool completely. Transfer to an airtight container and refrigerate for up to 3 days. To reheat, microwave individual portions or place back in the oven at 350°F until heated through. This dish also freezes well—just wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I use different types of sausage?

Absolutely. Kielbasa, Andouille, or even chicken sausage all work well depending on your flavor preference.

Do I need to thaw the frozen pierogies first?

No need! Just place them directly in the baking dish. They cook perfectly in the oven.

Can I make this ahead of time?

Yes. Assemble everything in the dish, cover tightly, and refrigerate up to 24 hours before baking. You may need to add a few extra minutes to the bake time if baking straight from the fridge.

What cheese is best for this recipe?

Sharp cheddar gives it that classic comfort flavor, but feel free to mix in mozzarella or pepper jack for a twist.

Is this casserole spicy?

Not inherently. If you’d like some heat, use a spicy sausage or add a pinch of red pepper flakes to the sauce.

Can I make it vegetarian?

Sure! Just skip the sausage and add sautéed mushrooms, spinach, or bell peppers for flavor and texture.
