Heat a small saucepan over medium/high heat and add the butter to the saucepan. When the butter is melted, add the garlic to the butter. Sauté the garlic in the butter for 1-2 minutes until fragrant.

Add the all-purpose flour to the butter and whisk the two ingredients together. Cook the butter and flour mixture for 2 minutes.

Slowly pour the milk to the saucepan, whisking constantly as you add the milk to the butter and flour mixture. The mixture should thicken pretty quickly.

Once the mixture has thickened, remove the saucepan from the heat and add the parmesan cheese. Stir the cheese into the thickened mixture until the cheese is completely melted.

Place the saucepan over the heat and turn the heat to low. Add the salt, fresh thyme, and ground pepper to the sauce and stir to combine.

Serve over chicken wings, as a warm dip for vegetables, or toss with pasta sauce.
