A delightful twist on a classic casserole, combining the tangy flavors of sauerkraut with the richness of kielbasa and cheese, topped with a golden biscuit crust.
Preheat your oven to 400°F.
Ensure your oven is fully preheated to achieve even cooking.
In a mixing bowl, combine the sauerkraut, mayonnaise, and horseradish until well mixed.
Mix thoroughly to ensure the flavors are evenly distributed.
Spread the sauerkraut mixture evenly in the bottom of a greased 8x8-inch casserole dish.
Use the back of a spoon to smooth out the layer.
Arrange the sliced kielbasa over the sauerkraut mixture.
Ensure the kielbasa slices are evenly distributed for consistent flavor.
Sprinkle the Swiss cheese evenly over the kielbasa.
For extra cheesiness, add a bit more cheese.
Bake the casserole in the preheated oven for 15 minutes.
Check the casserole halfway through to ensure even cooking.
Place the biscuits on top of the casserole and bake for an additional 13-15 minutes, or until the biscuits are golden brown.
Brush the biscuits with melted butter for a golden finish.
Remove from the oven and let cool slightly before serving.
Allowing the casserole to cool slightly helps the layers set.
