Add butter, flour, salt, black pepper, and garlic powder to a skillet and heat over medium heat until browned, whisking frequently.
Slowly whisk in milk until no longer lumpy.
Heat gravy until it begins to thicken, which takes about 5 minutes.
Serve white gravy immediately over warm flaky biscuits. Serves approximatly 6-8 biscuits.
Notes
Seasoning VariationsI like to keep creamy gravy simple with salt, pepper, and garlic. However, feel free to flavor it with other savory seasonings and herbs like basil, oregano, thyme, and onion powder. Gravy also does well with a spicy kick like Slap Ya Mama Seasoning. How to thin gravyIf gravy cooks too long, it can become thick. It's so easy to thin out gravy by whisking in a bit of milk a little at a time until the consistency is desired. Can Gravy be made ahead of time? It can, but the fridge will thicken up the gravy. To reuse, pour into a saucepan and heat on low on the stove. Add a bit of heavy whipping cream or additional milk to thin as needed.
