Step 1

Preheat the oven to 400 degrees F (200 degrees C). Spread french fries out on a baking sheet. Bake for 20 minutes in the preheated oven, or until golden brown.

Step 2

Meanwhile, divide the ground beef into four equal parts and form into patties. Fry the patties in a large skillet over medium-high heat until well done, about 4 minutes per side.

Step 3

Melt the butter in a saucepan over medium heat and whisk in the flour. Cook while stirring constantly for 4 minutes to cook out the flavor of raw flour. Gradually whisk in the half-and-half so that no lumps form. Bring to a simmer then remove from the heat and add the cheese; stir until melted. Season with salt, pepper, and hot sauce to taste.

Step 4

Place 2 slices of toasted bread onto 2 dinner plates and top each slice with a hamburger patty. Top each patty with cooked french fries. Pour the cheese sauce on top of everything and serve immediately.
