This Easy Crockpot Pierogi Casserole is a cozy dish packed with tasty pierogis, hearty kielbasa, and gooey cheese. Just toss everything in the slow cooker and let it work its magic!
I love how simple this recipe is! You basically just need to layer it all in the crockpot, then kick back while it cooks. Perfect for busy days when you want a warm meal waiting for you!
Key Ingredients & Substitutions
Pierogis: Frozen pierogis are a must for this recipe. I prefer using cheese and potato ones, but you can also choose sauerkraut or mushroom varieties for a different twist.
Kielbasa: This adds lots of flavor, and I love how it complements the pierogis. If you’re looking for a lighter option, turkey kielbasa works great. For a vegetarian version, consider using sautéed mushrooms or a meat substitute.
Cheddar Cheese: Cheddar is my go-to for this dish because it melts beautifully. You can also try Monterey Jack or a cheese blend for a creamier texture.
Sour Cream: I use sour cream for a rich and tangy flavor, but Greek yogurt is a great substitute if you want a healthier option. You can even skip it if you prefer a lighter casserole.
How Do I Get the Best Flavor in My Casserole?
The key to a flavorful casserole is to sauté the kielbasa, onions, and garlic first. This step enhances their taste and adds a delicious base for your layers. Here’s how to do it:
- Heat olive oil or butter in your skillet over medium heat.
- Add the sliced kielbasa and cook until slightly browned, about 5 minutes.
- Incorporate the sliced onion and minced garlic, cooking until the onions are soft (3-4 minutes).
- Let this mixture cool slightly before layering it in the crockpot.
Enjoying this dish becomes even easier when you focus on these steps for special flavors!

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and then you’ll let the crockpot do the work for 3-4 hours on low. It’s a great option for those busy days when you want a tasty meal waiting for you!
Step-by-Step Instructions:
1. Prepare the Crockpot:
Start by lightly greasing the inside of your crockpot with butter or non-stick spray to prevent sticking.
2. Cook the Kielbasa and Onions:
In a skillet, add olive oil or butter and heat it over medium heat. Add the sliced kielbasa. Cook for about 5 minutes, stirring occasionally, until it starts to brown. Then, add the sliced onions and minced garlic. Cook for another 3-4 minutes until the onions become soft and translucent. Once done, remove from heat.
3. Mix the Creamy Sauce:
In a mixing bowl, whisk together the sour cream and heavy cream (or milk) until you have a smooth mixture. It will add a rich flavor to your casserole!
4. Start Layering:
Now it’s time to assemble! Begin by layering half of the frozen pierogis evenly on the bottom of the crockpot.
5. Add Kielbasa and Onions:
Spread half of the cooked kielbasa and onion mixture evenly over the layer of pierogis.
6. Pour the Creamy Mixture:
Next, pour half of the creamy sour cream mixture over the layers. This ensures that everything gets deliciously combined.
7. Cheese Time:
Sprinkle 1 cup of shredded cheddar cheese evenly on top. Who doesn’t love cheesy goodness?
8. Repeat the Layers:
Now, repeat the layering process with the remaining pierogis, followed by the leftover kielbasa and onion mixture, the rest of the cream mixture, and finish it off with the last 1 cup of cheddar cheese on top.
9. Cook to Perfection:
Cover the crockpot and cook on low for about 3-4 hours. Check on it after 3 hours to make sure the pierogis are tender and the cheese is melted and bubbly.
10. Garnish and Serve:
Once it’s done cooking, garnish your delicious casserole with chopped parsley or green onions. Serve warm and enjoy this comforting, cheesy delight!
This recipe is very flexible—feel free to add sautéed mushrooms or bell peppers for extra flavor. Happy cooking!
FAQ for Easy Crockpot Pierogi Casserole with Kielbasa
Can I Use Fresh Pierogis Instead of Frozen?
Yes, you can use fresh pierogis! However, you should adjust the cooking time slightly, as fresh pierogis may cook faster than frozen ones. Start checking for doneness around the 2-3 hour mark.
What Can I Substitute for Kielbasa?
If you’re looking for a lighter option, turkey kielbasa is a great substitute. For a vegetarian version, try using sautéed mushrooms, tempeh, or a meat alternative like Beyond Sausage for a similar texture.
How Do I Store Leftover Casserole?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it up in the microwave or in a skillet over low heat, adding a splash of milk or cream if it seems too dry.
Can I Add Vegetables to This Recipe?
Absolutely! Adding vegetables like bell peppers, spinach, or mushrooms is a fantastic way to customize this dish. Just sauté them with the kielbasa and onions before layering them in the crockpot for added flavor and nutrition.
