A hearty and flavorful casserole combining savory sausage, tangy sauerkraut, and creamy mashed potatoes, topped with melted cheese.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking and the right texture for your casserole.
Butter a 9x13 inch casserole dish to prevent sticking.
Using unsalted butter adds flavor without extra salt.
Spread half of the mashed potatoes evenly on the bottom of the dish.
Ensure the layer is even for consistent baking.
Layer half of the sauerkraut over the mashed potatoes.
Draining the sauerkraut slightly prevents excess moisture.
Repeat the layers with the remaining mashed potatoes and sauerkraut.
Press gently to compact the layers for better structure.
Distribute the pork sausage and kielbasa evenly over the top.
Cook the sausage slightly beforehand for enhanced flavor.
Sprinkle ground black pepper over the top.
Adjust the pepper to your taste preference.
Top with shredded cheddar cheese.
Use freshly shredded cheese for better melting.
Bake in the preheated oven for 35-40 minutes, until the cheese is melted and bubbly.
Check at 35 minutes to avoid over-browning.
Let the casserole cool for 5 minutes before serving.
Cooling helps the layers set for easier serving.
