Kentucky Hot Brown

1. To roast the turkey, preheat the oven to 425 degrees F. Rub the entire breast with 4 tablespoons butter and season with salt and pepper. Place in a small roasting pan and roast for 15 minutes. Reduce the heat to 350 degrees F and continue roasting the turkey until a thermometer inserted into the center registers 155 degrees F, 1 to 1 ½ hours. Remove from the oven, tent loosely with foil, and let rest for 10 minutes before slicing.

2. To make the sauce, put the milk in a small saucepan and bring to a simmer over low heat. Melt the remaining 2 tablespoons butter over medium-high heat in a medium saucepan. Whisk in the flour and cook for 1 minute. Gradually whisk in the hot milk. Bring to a boil and cook, whisking constantly, until thickened and the raw flour haste has cooked out, 4 to 5 minutes. Stir in more milk if the sauce is too thick to pour.

3. Remove from the heat and whisk in the cheddar and Parmesan cheeses, whisking until the cheddar has melted. Season with the nutmeg and salt and pepper to taste. Keep warm.

4. To make the sandwiches, whisk together the eggs and milk in a medium baking dish. Season with salt and pepper. Dip each slice of bread in the mixture and let sit until completely soaked through, about 10 seconds per side.

5. Heat 1 tablespoon of the butter and 1 tablespoon of the oil in a large nonstick sauté pan over medium-high heat. Working in batches, cook 2 slices of the bread at a time until golden brown on both sides, about 2 minutes per side. Repepat with the remaining butter, 3 tablespoons oil, and bread.

6. Preheat the broiler. Put the tomatoes on a rimmed baking sheet, brush with the remaining 2 tablespoons oil, and season with salt and pepper. Broil until slightly charred and just cooked through, 3 to 4 minutes.

7. Place 4 slices of the egg bread on a baking sheet, slide under the broiler, and heat just to warm through, 20 seconds on each side. Repeat with the remaining bread.

8. Top each slice of bread with 2 to 3 slices turkey. Ladle sauce over the top and divide the cheddar and Parmesan over the top of each slice. Place under the broiler and cook until bubbly and the tops are golden brown, about 2 minutes. Remove from the oven, top each slice with 2 slices of bacon and a tomato slice, and sprinkle with parsley.
