For the Sauce:

Instructions
-
Prepare the Bread Crumbs:
- Shred about 2 slices of rye bread to make 1/2-3/4 cup of bread crumbs. Set aside.
-
Layer the Casserole:
- Butter enough of the remaining rye bread to line the bottom of a large casserole dish, placing it buttered side down.
-
Prepare the Sauerkraut and Pork Mixture:
- In a skillet, melt 1 tablespoon of butter and sauté half of the diced onions with the ground pork until the onions are lightly browned.
- Mix the sautéed onion and pork mixture into the sauerkraut.
-
Prepare the Mushroom Sauce:
- In the same skillet, melt 2 tablespoons of butter and sauté the remaining diced onions and sliced fresh mushrooms until the onions are clear.
- In a small saucepan, combine sour cream, mustard, 1 tablespoon of flour, and milk. Heat over low heat, stirring constantly until the mixture thickens.
- Gradually stir in the chicken or beef broth, continuing to heat and stir until the sauce thickens again.
- Stir the sautéed mushroom mixture into the sauce.
-
Assemble the Casserole:
- Spread the sauerkraut and pork mixture evenly over the buttered rye bread in the casserole dish.

- Mix the melted butter with the rye bread crumbs and spread the mixture over the kielbasa.
-
Bake the Casserole:
- Cover the casserole dish tightly with foil.
- Bake in a preheated 350°F oven for about 25-35 minutes, or until the noodles are tender.
-
Finish with Cheese:

Serve and Enjoy:
- Once baked, remove the casserole from the oven and let it rest for a few minutes before serving.
- Serve hot, alongside a fresh tomato salad, pickles, and additional rye bread for a complete and satisfying meal.
Recipe Notes and Variations
-
Shortcut Option: If you prefer a quicker version, you can substitute two 10 1/2-ounce cans of Cream of Mushroom soup and 1 1/2 cups of milk for the scratch-made mushroom sauce. Simply mix the soup, mustard, and remaining sautéed onions with milk and use in place of the scratch sauce in the recipe.
-
Ingredient Tips: Ensure the kielbasa is fully cooked before layering it into the casserole. Adjust the amount of cheese according to your preference for richness.
