For the sausage gravy:

  • 1 pound bulk breakfast sausage hot or mild
  • 1/3 cup flour
  • 4 cups whole milk
  • 1/2 teaspoon seasoning salt
  • 1 & 1/2 - 2 teaspoons freshly ground black pepper

For the egg mixture:

  • 6 eggs
  • 1/2 cup milk
  • 3/4 teaspoon seasoning salt
  • 1/4 teaspoon dry mustard
  • 1/4 teaspoon paprika
  • 1/2 teaspoon salt
  • pepper to taste
  • 1 can Pillsbury Grands Biscuits
  • 1 cup cheddar cheese shredded


  • In a large skillet, brown the sausage over medium-high heat, breaking it up into small pieces with a wooden spoon.
  • Reduce the heat to medium-low. When the sausage is cooked and no longer pink, sprinkle half of the 1/3 cup flour on the sausage and stir until it is absorbed. Add the rest a little at a time, and stir until all the flour is soaked up. Stir for 1 more minute to get the flour taste out.
  • Turn the heat to medium. Pour in the milk, 1 cup at a time, stirring to thicken it up each time.
  • Once you have added all the milk, continue stirring for another 10-12 minutes until the gravy has thickened up some.
  • Add 1/2 teaspoon seasoning salt and 1 and 1/2 to 2 teaspoons pepper.
  • Meanwhile, mix together the eggs. Break the eggs into a large bowl or stand mixer and whisk. Add 1/2 cup milk, 3/4 teaspoons seasoning salt, mustard, paprika, 1/2 teaspoon salt, and pepper to taste.*
  • Grease a 9x13 inch casserole dish. Open the can of biscuits and separate all the biscuits. Use scissors to cut each biscuit into 4 pieces.
  • Drop the quartered biscuits onto the prepared pan and spread them out evenly.
  • Pour the egg mixture over the biscuits.
  • Sprinkle with 1 cup cheese.
  • Pour the gravy over the cheese and spread it out.
  • (At this point you can cover tightly and refrigerate overnight).
  • Bake in a preheated 350 degrees F oven for about 38-45 minutes if you are making is right away.
  • If you have just taken it out of the fridge, cover with aluminum foil.
  • There is no need to preheat the oven first. Just put it in the oven and turn it on to 350 degrees.
  • Bake for about 30 minutes, then remove the foil. Continue baking for another 15-30 minutes, or until the biscuits have browned and the sauce is bubbly. (45-60 minutes total if it's been in the fridge overnight).


*All of the spices I put in the eggs are totally optional. That's the way I like it, but you can add just salt and pepper if you want to keep it simple.
