Main Ingredients

  • 1 16 oz can refrigerated buttermilk biscuits (8-count)
  • 1 lb breakfast sausage (pork or turkey)
  • 1/4 cup all-purpose flour
  • 2 1/2 cups whole milk (for gravy)
  • 6 large eggs
  • 1/2 cup milk (for eggs)
  • 1 cup shredded cheddar cheese (optional)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • N/A Nonstick cooking spray For baking dish preparation

Instructions
 

Preparation

  • Gather all your ingredients and preheat your oven to 350°F (175°C). Spray a 9x13-inch baking dish with nonstick cooking spray.

Cooking the Sausage

  • In a large skillet over medium heat, cook the breakfast sausage until browned and fully cooked—about 8-10 minutes. Do not drain the fat.

Making the Gravy

  • Sprinkle the flour over the cooked sausage and stir to coat. Gradually pour in the 2 1/2 cups of whole milk while stirring constantly. Let it simmer until thickened, about 5-7 minutes. Season with salt and pepper.

Preparing the Biscuits

  • Cut each biscuit into quarters and scatter them evenly across the bottom of the prepared baking dish.

Assembling the Casserole

  • Pour the sausage gravy mixture over the biscuits. In a separate bowl, whisk together the eggs, 1/2 cup of milk, and additional salt and pepper. Stir in the cheese if using, then pour evenly over the casserole.

Baking

  • Place the casserole in the preheated oven and bake uncovered for 35-40 minutes until the eggs are set and biscuits are golden.

Serving

  • Remove from oven and cool for 5-10 minutes before slicing and serving.

Notes

Customize with jalapeños for spice or swap turkey sausage for a lighter option. Can be made a day in advance.
