In a medium sauce pan, melt butter over medium-high heat.

Slowly whisk in ½ cup flour and stir continuously. Let bubble for 2 minutes while stiring with a whisk.

Pour in 2 cups milk and whisk for 1 minute on medium heat until it thickens.

Turn heat to low and stir in shredded cheese.

Season with ground mustard, salt, pepper, and onion powder. Stir until mixed well and cheese is fully melted.

This recipe is the perfect amount to use with 1 lb cooked pasta.

Enjoy!
