Crock Pot Pierogi Casserole With Kielbasa
Prep time: 15 minutes Cook time: 4-6 hours (low) or 2-3 hours (high) Total time: 4 hours 15 minutes Servings: 6-8 Calories: Approximately 600 kcal per serving
Ingredients:
- 1 tablespoon olive oil
- 1 large yellow onion, thinly sliced
- 1.5 lbs smoked kielbasa sausage, sliced into 1/2-inch rounds
- 1 can (10.5 oz) cream of mushroom soup (or cream of chicken)
- 1 can (10 oz) Rotel diced tomatoes with green chiles, undrained
- 1/2 cup chicken broth
- 1 teaspoon dried parsley
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 1 (16 oz) package frozen potato and cheese pierogi (do not thaw)
- 2 cups shredded cheddar cheese, divided
- 1/2 cup sour cream (for serving)
- Fresh chives or parsley, chopped (for garnish)
Instructions:
- Sauté Onions & Kielbasa (Optional but Recommended!): Heat olive oil in a large skillet over medium heat. Add sliced onion and cook for 5-7 minutes, until softened and lightly caramelized. Add sliced kielbasa and cook for another 3-5 minutes, just until lightly browned. This step builds so much flavor! (If skipping, just add raw onions and kielbasa directly to the slow cooker).
- Mix Sauce: In a large bowl, whisk together the cream of mushroom soup, Rotel, chicken broth, dried parsley, garlic powder, and black pepper.
- Layer Slow Cooker: Spray your slow cooker insert with non-stick spray. Add half of the frozen pierogi to the bottom in an even layer. Top with half of the cooked kielbasa and onions. Pour half of the sauce mixture over the top. Sprinkle with 1 cup of shredded cheddar cheese.
- Repeat Layers: Repeat the layers: remaining pierogi, remaining kielbasa and onions, remaining sauce, and finally, the last cup of shredded cheddar cheese.
- Cook: Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours, or until the pierogi are tender and the cheese is bubbly.
- Serve: Ladle into bowls and top each serving with a dollop of sour cream and a sprinkle of fresh chives or parsley.
