4-Ingredient Slow Cooker Pierogi Casserole is the ultimate comfort-food shortcut. With just a handful of ingredients and a slow cooker, you get all the cozy flavors of classic pierogies without the extra work. Creamy, cheesy, and satisfying, this dish is perfect for busy weeknights, potlucks, or when you want something hearty with minimal effort.
Ingredients
- 1 package frozen potato and cheese pierogies
- 1 cup shredded cheddar cheese
- 1 cup sour cream
- 225 g smoked sausage or kielbasa, sliced
Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the inside of the slow cooker to prevent sticking and make cleanup easier.
Step 2: Add the Ingredients
Place the frozen pierogies in the bottom of the slow cooker. Add the sliced sausage evenly over the top. Spoon the sour cream over the pierogies and sausage, spreading it as evenly as possible.
Step 3: Add the Cheese
Sprinkle the shredded cheddar cheese over everything, making sure it is evenly distributed for a creamy, cheesy finish.
Step 4: Slow Cook
Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours, until the pierogies are tender and heated through and the cheese is fully melted.
Step 5: Stir and Serve
Gently stir the casserole before serving to coat the pierogies in the creamy sauce. Serve hot.
Tips for Best Results
Use frozen pierogies straight from the freezer without thawing. Smoked sausage or kielbasa adds the best flavor, but you can use any fully cooked sausage you like. Stir gently to avoid breaking the pierogies.
Serving Suggestions
This casserole is filling on its own but pairs well with a simple green salad or steamed vegetables to balance the richness.
Make-Ahead and Storage
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop with a splash of milk or water to loosen the sauce.
Variations
You can add sautéed onions for extra flavor if you do not mind using an extra ingredient. For a creamier version, mix the sour cream with a little milk before adding it to the slow cooker.
Conclusion
4-Ingredient Slow Cooker Pierogi Casserole proves that simple ingredients can create big comfort. Creamy, cheesy, and effortless, this recipe is perfect when you want a warm, satisfying meal with almost no prep.
