Muffin Tin Potatoes Gratin

Ingredients

Preheat oven to 400 degrees F (200 degrees C).
Spray 12 muffin cups with cooking spray or grease with butter.
Heat butter in a saucepan over medium heat.
Cook and stir garlic in the melted butter until fragrant, about 1 minute.
Add flour to the garlic mixture; cook and stir until the mixture is smooth and thickened, about 2 minutes.
Slowly pour milk into the flour-butter mixture while continuously stirring with a whisk until the sauce is smooth and thickened, about 5 minutes.
Remove the saucepan from heat and stir Parmesan cheese into the sauce until the cheese melts from the heat of the sauce; season with salt and pepper.
Divide the potatoes among the 12 prepared muffin cups and spoon cheese sauce over the potatoes.
Bake in the preheated oven until potatoes are tender, about 25 minutes.
