Step-by-Step Cooking Instructions

Follow these easy steps to make your Crockpot Pierogi Casserole with Kielbasa:
1. Prepare the Kielbasa and Onion
Start by heating a small amount of oil in a skillet over medium heat. Add the sliced kielbasa and diced onion, sautéing for about 5-7 minutes until the onions are soft and the kielbasa is slightly browned. This step is optional but adds a deeper flavor to the casserole.
2. Layer the Pierogies and Kielbasa
Spray your crockpot with non-stick cooking spray or use a liner for easy cleanup. Begin by layering half of the frozen pierogies in the bottom of the crockpot. Then, spread half of the kielbasa and sautéed onion mixture over the pierogies. Repeat with the remaining pierogies and kielbasa to create two layers.
3. Make the Creamy Sauce
In a medium mixing bowl, combine the cream of mushroom (or chicken) soup, sour cream, minced garlic, and paprika. If the mixture is too thick, you can thin it out with chicken broth or water. Stir in 1½ cups of the shredded cheddar cheese, reserving the remaining ½ cup for later.
4. Pour the Sauce Over the Casserole
Pour the creamy mixture evenly over the layered pierogies and kielbasa. Use a spatula to spread the sauce, ensuring that all the pierogies are covered.
5. Cook in the Crockpot
Cover the crockpot and cook on low for 3-4 hours or high for 2-3 hours. The pierogies should be tender, and the sauce should be hot and bubbly.
6. Add Cheese and Finish
In the last 15-20 minutes of cooking, sprinkle the remaining ½ cup of cheddar cheese on top of the casserole. Cover and let the cheese melt.
7. Garnish and Serve
Once the cheese is melted and everything is hot and creamy, remove the crockpot lid. Garnish with fresh parsley and serve the casserole hot. This dish pairs well with a side salad or steamed veggies.
How to Cook Crockpot Pierogi Casserole with Kielbasa: A Step-by-Step Guide
- Don’t Overcook: The key is to cook the pierogies just long enough to become tender but not mushy. Check the pierogies toward the end of cooking to ensure they’re soft but holding their shape.
- Sauté for Extra Flavor: While you can add the kielbasa and onion straight to the crockpot without sautéing, browning them first adds extra depth of flavor and texture to the dish.
- Adjust the Sauce Consistency: If you prefer a looser sauce, you can add extra chicken broth or a splash of milk. For a thicker sauce, reduce the amount of liquid or add a little cream cheese.
Common Mistakes to Avoid
- Forgetting to Spray the Crockpot: This dish can be sticky due to the cheesy sauce. Make sure to spray your crockpot with non-stick spray or use a liner to prevent sticking and make cleanup easier.
- Overcooking the Pierogies: Check your pierogies to make sure they don’t become too soft or mushy, as overcooking can cause them to lose their structure.
- Not Stirring the Cheese into the Sauce: Make sure to mix the cheese into the sauce before pouring it over the pierogies. This ensures even distribution of the cheesy goodness throughout the casserole.
Serving and Presentation Tips
While this is a cozy and rustic dish, you can still make it visually appealing with thoughtful garnishes and sides. Here’s how to serve and present your Crockpot Pierogi Casserole:
- Serve with a Side Salad: A fresh green salad with a tangy vinaigrette will balance out the richness of the casserole.
- Add a Crunchy Side: Serve with garlic bread or crusty baguette slices to add a crunchy contrast to the creamy dish.
- Top with Fresh Herbs: Garnish with freshly chopped parsley or chives to add a pop of color and brightness to the dish.
How to Serve Crockpot Pierogi Casserole with Kielbasa
