- 3 tablespoons butter
- 3 tablespoons flour
- 1 pint heavy cream
- 3 ounces Pecorino Romano cheese (about 1 1/2 cups)
- Kosher salt and freshly ground black pepper
- 10 ounces freshly ground beef, formed into two 5-ounce patties
- 2 slices hearty white toast
- 4 slices bacon, crisply cooked
- 4 slices ripe tomato
- Dash paprika
- 2 tablespoons finely chopped fresh parsley leaves
- Preheat broiler or toaster oven to high. Melt butter in a small saucepan over medium-high heat. Add flour and whisk to combine. Continue to cook, whisking constantly until pale golden blond, about 1 minute. Slowly pour in heavy cream, whisking constantly. Bring to a simmer then remove from heat. Whisk in grated cheese, then season to taste with salt and pepper.
- When ready to serve, season burger patties generously with salt and pepper and cook burgers to desired doneness on a hot grill or in a skillet on the stovetop, 125°F for medium rare or 135°F for medium. Let burger patties rest for 5 minutes off heat.
- Place 1 slice toast in the bottom of each gratin dish or both slices in the bottom of one oval baking dish and top each with a burger patty. Pour half the sauce over each sandwich, completely coating it. Place under broiler until spotty brown and bubbly, 2 to 3 minutes. Place 2 slices of bacon in a cross on top of each dish and add 2 slices of tomato to the side of the toast. Sprinkle with paprika and parsley and serve immediately with a knife and fork.
