Step 1

Preheat the oven to 400°F and lightly coat a 7 x 11-inch baking dish with cooking spray.

Step 2

Cut the biscuits into quarters and place half of the biscuits in the baking dish. Bake for 10 minutes.

Step 3

While the biscuits are baking, brown the sausage in a skillet over medium heat until fully cooked. Remove and drain. Add the butter to the empty skillet and melt over low heat. Then whisk in the flour and cook for 2 minutes. Add the milk, salt, pepper, and cayenne, bring to a low boil, and cook until thick. Return the sausage to the skillet with the gravy and stir to combine.

Step 4

Pour the mixture over the biscuits and layer the remaining biscuits on top. Bake for 30 minutes, until the top of the casserole is golden brown. Serve.
