Let’s walk through the steps to bring this comforting dish to life. Just as Mama Lou guided me through my first culinary adventures, let me guide you:

1. Preheat your oven to 375°F (190°C) to prepare for a delicious transformation.
2. In a large bowl, combine the corned beef, sauerkraut, and half of the shredded Swiss cheese. Mix until well combined, reminiscent of the way Mama Lou would tell us stories that intertwined seamlessly.
3. In a separate bowl, whisk together the cream cheese, mayonnaise, Dijon mustard, heavy cream, and caraway seeds until smooth. This creamy mixture will serve as the glue that binds the flavors together, much like the bonds of family.
4. Combine the dry and wet ingredients, ensuring every piece is coated with the creamy mixture. Season with salt and pepper to taste, remembering that balance is the key in both cooking and life.
5. Transfer the mixture to a greased baking dish, spreading it evenly like layers of a cherished story.
6. Sprinkle the remaining Swiss cheese on top, allowing it to melt into a golden crust that will evoke smiles around the table.
7. Bake for 25-30 minutes, or until the top is bubbly and golden. As it bakes, let the aroma transport you to a place of warmth and nostalgia.

As you pull the casserole from the oven, let it cool slightly before serving, just as Mama Lou would always remind us to have patience, for the best things in life are worth waiting for.
