Preparation
- Preheat your oven to 375°F (190°C).
- In a large skillet over medium heat, add your chopped onion and sausage. Cook until the sausage is browned and the onions are translucent, about 5-7 minutes.
- In a greased casserole dish, layer half of the frozen pierogi on the bottom. Optionally, you can add the sauerkraut over this layer.
- Spread half of the sausage and onion mixture over the layer of pierogies.
- Spread half of the shredded cheese and all of the sour cream over the sausage. Then repeat the layers: remaining pierogi, sausage mixture, and top with the remaining cheese.
- Sprinkle salt and pepper on top.
- Cover with aluminum foil and bake for 20 minutes. Uncover and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.
- Remove from the oven, allow to cool slightly, and garnish with chopped green onions before serving.
Notes
If you have leftovers, store the casserole in an airtight container in the refrigerator for up to 3 days. For longer storage, wrap tightly and freeze for up to 3 months. Thaw in the fridge overnight and reheat in the oven at 350°F (175°C) for 20-25 minutes.
