Stir in flour and cook for 2-3 minutes until bubbly and slightly browned. Whisk the entire time while it is browning.
¼ cup flour
Slowly whisk in milk. Cook over medium heat until the milk begins to thicken. Whisk often to prevent scorching.
2 cups milk
Add seasonings and turn heat to low.
½ teaspoon salt, ½ teaspoon pepper, ¼ teaspoon garlic powder
Continue whisking until the gravy reaches desired thickness.
Serve hot.
Notes
Use a heavy skillet. It will help diffuse the heat and prevent scorching. If you only have a thin skillet, reduce heat to low.
Whisk milk in slowly. This will help prevent lumps from forming. If small lumps do form, whisk to help remove them. You can strain your gravy through a sieve to remove any lumps if needed.
