Heat a large skillet over medium heat. Add the sausage, break into pieces, and cook until browned and no longer pink, about 5 minutes.
Sprinkle flour over the cooked sausage and stir continuously for 1 minute until golden.
1 pound breakfast sausage
Slowly whisk in milk until silky smooth. Simmer gently for 2–3 minutes until thickened.
3 tablespoons all-purpose flour
Season with salt and pepper to taste. Serve immediately over warm biscuits.
2 cups milk, 0.25 teaspoon salt
Notes
I found that browning the sausage one minute longer gave a richer nutty taste.Whisking in milk gradually prevented lumps and created a glossy texture.Store cooled leftovers in an airtight container in the fridge for up to 4 days; reheat gently over low heat.
