Step 1: Preheat the Oven

• Preheat your oven to 350°F (175°C).

• Lightly grease a 9×13-inch baking dish with butter or nonstick spray.

Step 2: Par-Bake the Biscuits

• Cut each biscuit in half.

• Arrange half the biscuit halves evenly across the bottom of the dish.

• Bake for 10 minutes, just until lightly golden.

Step 3: Brown the Sausage

• In a skillet over medium heat, cook the ground sausage until fully browned and crumbled.

• Do not drain unless excess grease remains.

Step 4: Make the Sausage Gravy

• Sprinkle flour over the sausage and stir to coat.

• Cook for 2–3 minutes to remove the raw flour taste.

• Gradually whisk in the milk, stirring constantly to avoid lumps.

• Add salt and black pepper, and continue to simmer until the mixture thickens (about 5 minutes).

Step 5: Assemble the Casserole

• Pour the hot sausage gravy evenly over the pre-baked biscuits in the dish.

• Top with the remaining biscuit halves.

Step 6: Final Bake

• Return the dish to the oven and bake for 25–30 minutes, or until biscuits on top are golden and the casserole is bubbling.

Step 7: Cool and Serve

• Let the casserole cool for 5–10 minutes before slicing.

• Serve warm with a sprinkle of fresh herbs, if desired.
