• Heat butter in a pan. Add garlic and fry for a few seconds.
• Add flour and fry for a minute on low heat.
• Add milk gradually and keep whisking continuously to make a lump free mixture.
• Add chicken broth and cook until the sauce thickens.
• Add parmesan cheese, garlic powder, salt and black pepper and cook until cheese melts. Use the sauce as required.

Notes:

• Make sure there are no lumps after you add milk in the flour. To do this use a wire whisk vigorously to mix while pouring the milk.
• Chicken broth adds a nice flavor to the sauce, so make sure to use a nice one.
