8slicesbacon (lower-sodium), cut into lardons (1/4" matchsticks)
8mini croissants, sliced in half
8ouncedeli turkey (lower-sodium), sliced as thick as you like
1cupcherry tomatoes, halved
1tablespoonunsalted butter
2tablespoonall purpose flour
2tablespoonbourbon
1½cupsmilk (2% or whole), warmed
1dashnutmeg
6ouncegruyere cheese, shredded, divided
kosher salt + fresh cracked black pepper
1tablespoonfresh thyme leaves
Instructions
Place an oven rack in the upper third of the oven and preheat the broiler.
Place the bacon lardons in a cool skillet and set over medium heat (note 1). Cook the bacon until crisp, stirring occasionally for even cooking. Using a slotted spoon, transfer the bacon to a paper towel drain. Remove all but 1 tbsp of the bacon fat from the skillet. Set it aside.
Spritz a 9 by 13-in casserole with cooking spray. Arrange the halved mini croissants across the bottom of the dish. Arrange the turkey over the croissants in puddles, but so it covers the bread. Sprinkle the halved tomatoes evenly over the turkey.
Add the butter to the skillet with the bacon fat and place it over medium heat. Once the butter has melted, whisk in the flour and cook for 1 to 2 minutes, stirring constantly. Next, whisk in bourbon, then follow immediately with the warm milk and continue stirring until the sauce is smooth and creamy and begins to thicken (note 2). Take the saucepan off the heat and stir in the nutmeg and 4 oz of gruyere until completely melted. Season to taste with kosher salt + black pepper.
Pour the sauce evenly over assembled ingredients in the casserole dish. Broil the casserole for 3 minutes. Remove from the oven and sprinkle with the bacon and remaining 2 oz of gruyere. Broil for another 2 minutes.
Garnish with fresh thyme before serving.
Notes
1. Place the lardons in a cold skillet, then place it on the burner. This allows the fat to slowly render out and create crispy, not soggy, bacon.2. Warm or hot milk will help prevent lumps and create a smooth sauce. It will also thicken quicker. Simply warm it in the microwave for a minute or two or in a small saucepan on your cooktop.3. Transfer leftovers into an airtight container and store in the refrigerator for 2 to 3 days. Warm in the microwave or 350°F oven until heated through.See the full post for additional tips, substitutions and make ahead instructions.
