Preheat the oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish. Melt 6 tablespoons butter.

Place English muffin cubes in a large bowl and drizzle with the melted butter and Dijon mustard. Toss until evenly coated and spread them in a single layer on a baking sheet. Bake in the preheated oven until lightly browned and lightly toasted, 12 to 14 minutes.

Meanwhile, whisk the eggs, half-and-half, 1 teaspoon salt, and 1/2 teaspoon pepper together in a bowl until well combined; set aside.

Place half of the bread cubes in the prepared baking dish. Fold half of the ham slices, tear them into 1 1/2-inch pieces, and distribute the ham among the bread cubes. Evenly top with 2 cups of grated Swiss cheese.

Add the remaining bread, ham, and grated Swiss cheese. Pour the egg mixture over the casserole and press lightly to submerge most of the bread. Let stand at room temperature for 30 minutes.

Bake the casserole until the egg mixture is absorbed, 45 to 50 minutes. Cover with foil during the last 20 minutes of baking if the casserole is browning too quickly.

Meanwhile, melt the remaining butter in a saucepan over medium heat. Whisk in the flour and cook, stirring constantly, about 1 minute. Whisk in the milk until smooth. Bring the mixture to a boil, then reduce the heat to a simmer, stirring occasionally until thickened, about 3 minutes. Add the remaining salt, pepper, and nutmeg and stir. Cook about 8 minutes on low, stirring occasionally, then remove from the heat.

Remove the casserole from the oven and turn on the oven’s broiler. Pour the cream sauce over the casserole and top with grated Parmesan. Return the casserole to the oven and broil until bubbly and lightly browned, about 3 minutes. Let stand for 5 to 10 minutes. Sprinkle with chives and serve.

How easyChef Pro scores recipes and products
easyChef Pro analyzes up to 41 nutrients using data sourced from USDA and other verified food databases. Its scoring method uses the nutrients relevant to nutrition quality, calorie density, processing level, and your selected health goal. Recipes and food products get a health score from 0 to 100, calculated using consistent rules instead of being estimated by AI. The same nutrition data, serving size and health goal will produce the same result.
The calculation evaluates nutrients, calorie density, processing level, and how well the food supports your selected health goal. Protein, fiber, vitamins, minerals and other beneficial nutrients can strengthen the score. High amounts of sodium, saturated fat, added sugar and other nutrients may lower it.
Your health goal also matters. easyChef Pro evaluates recipes and products across six health areas and adjusts their importance for your selected goal. This means the same food may be a better fit for one health goal than another.
For recipes, changing an ingredient, quantity or serving size changes the nutrition and may change the score. Remix the recipe in easyChef Pro to calculate fresh nutrition and scores for the version you actually make. Product scores are based on the nutrition and serving information associated with that specific product.
