Kentucky Hot Brown Sliders take a traditionally open-faced sandwich and turn it into an appetizer with turkey, tomatoes, homemade cheese sauce, and bacon.
In a medium saucepan over medium heat, melt butter. Whisk in flour and cook until smooth and golden brown (1-2 minutes).
Slowly add in milk, whisking constantly.
Add the salt, pepper, and nutmeg. Continue cooking until thickened (3-5 minutes).
Remove from heat and add the cheeses. Whisk until melted. Set aside.
In a small bowl, mix together the melted butter, garlic salt, parsley, and salt. Set aside.
Preheat oven to 350°F. Spray a 9x13-inch baking dish with nonstick spray.
Split the rolls in half, placing the bottom halves in the prepared baking dish.
Top the buns with turkey, tomato slices, cheese sauce, and crumbled bacon.
Place the tops of the buns on top and brush with the melted butter mixture.
Cover the dish with aluminum foil and bake for 15 minutes, or until the cheese is hot and bubbly.
Remove foil and bake an additional 5 minutes, or until the tops of the sliders turn golden brown.
Remove from the oven, slice, and serve.
