Step by Step: How to Make Pierogi Casserole with Sausage
Step 1: Cook the Sausage and Onions
Slice sausage into bite sized pieces. Heat a large skillet over medium heat. Add the sausage and cook until browned, about 5 minutes. Add the chopped onion and garlic. Stir until the onion softens.
Step 2: Prepare the Baking Dish
Grease a 9×13-Inch baking dish with butter or nonstick spray. Spread half of the frozen pierogi in an even layer.
Step 3: Layer the Casserole
Top the pierogi with half the sausage and onion mixture. Add a few spoonfuls of sour cream and sprinkle with shredded cheese. Repeat the layers until all ingredients are used.
Step 4: Bake
Preheat oven to 375°F (190°C). Cover the dish with foil and bake for 25 minutes. Remove the foil and bake another 10 minutes until the cheese melts and bubbles.
Step 5: Serve
Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley or green onions if you like. Serve warm with a side salad or roasted vegetables.
