Ingredients

8–10 Idaho potatoes 3 cups of milk scalded (heat it to just below boiling point) 5 Tbsp butter 5 Tbsp flour 1/2 tsp mustard powder 1 1/2 cups shredded Swiss cheese Salmon and white pepper to taste 1 1/2 cups diced ham 5 or 6 slices of firm white sandwich bread (crusts removed and cubed) 3 tbsp melted butter Paprika, optional Grated Parmesan cheese, optional

Preparation

Step 1: Prepare the Potatoes

Start by baking the potatoes until they are fork tender. Allow them to cool on a wire rack until they are completely at room temperature. You can reserve this step to prepare the day before serving. Once cooled, peel the potatoes and dice them roughly. This step ensures that the casserole will be evenly seasoned and not too dry.

Step 2: Prepare the Cheese Sauce

Melt the butter in a heavy-bottomed saucepan over medium heat. Once melted, stir in the flour and cook for approximately 3 minutes, stirring constantly. As you stir, avoid browing the roux to keep the sauce smooth and creamy. Next, add the mustard powder and stir it into the sauce. Gradually pour in the scalded milk, one cup at a time, stirring vigorously to prevent lumps. Bring the sauce to a boil, then reduce the heat. Slowly incorporate shredded Swiss cheese, stirring until the sauce is smooth and glossy. Season with salt and white pepper to taste.

Step 3: Mix and Assemble

In a large mixing bowl, combine the diced ham and potatoes. Toss them together to distribute the ham evenly. Pour the cheese sauce over the ham and potatoes, then mix until the entire mixture is coated. Transfer this mixture to a buttered 9x13-inch baking pan. Use a fairly deep roasting pan to ensure the casserole bakes evenly.

Cover the casserole with a layer of parchment paper followed by aluminum foil to prevent the bread cubes from becoming soggy. Bake the casserole at 350°F (175°C) for 45 minutes. After 45 minutes, uncover and allow the casserole to bake for an additional 10–15 minutes to crisp the top. Sprinkle with fresh grated Parmesan cheese and paprika for an extra kick.

Step 4: Serve

After baking, let the casserole rest for 10–15 minutes to prevent the bread cubes from becoming too soggy. This resting period allows the flavors to meld together, creating a cohesive and delicious dish.

Serving Suggestions: The casserole can be enjoyed as a hearty meal with ham or as a side dish without the ham. It pairs well with roasted beef or ham. Serve alongside a fresh green salad and a light dessert like Bavarian cream for a satisfying dinner experience.

Tips and Variations

Alternative Cheeses: While Swiss cheese is traditional, you can experiment with cheddar or Gouda for a different taste. Meat Substitutions: Omit the ham and increase the bread cubes for a vegetarian option. Or, add cooked chicken for a different flavor profile. Spice Adjustments: Increase or decrease the amount of paprika and mustard powder according to your preference.

Auntie Ginnie's Delmonico Casserole is a versatile and delicious recipe that is sure to become a family favorite. Whether you're hosting a dinner party or simply looking for a comforting meal, this casserole is a perfect choice.
