How to make the biscuits:

How to make the sausage (will go in casserole and gravy):

  • 1 1/2 pounds ground pork
  • 1 1/2 T sage dried or minced fresh
  • 1 1/2 tsp kosher salt
  • 1 1/2 tsp brown sugar
  • 1 tsp pepper freshly ground
  • 1/2 tsp marjoram fresh if you have it
  • 1/8 tsp ground cloves

For the casserole:

  • 1/3 of the cooked sausage from above
  • 1/2 cup cheddar cheese grated
  • 1/2 cup pepper jack cheese grated
  • 8 whole eggs beaten
  • 1 cup whole milk

For the gravy:

  • 2/3 of the cooked sausage from above
  • 3 tbsp butter
  • 1/4 cup all-purpose flour
  • 3 cups whole milk


To make the biscuit dough:

  • In a medium sized bowl, combine flour, baking powder, salt, and sugar. For best results, freeze mixture for at least 15 minutes to get it really cold. Add in butter by grating cold butter over dry ingredients. Mix well to ensure each piece of butter is coated with the flour mixture.
  • Make a well in the middle and add the buttermilk. Use your hands to mix just enough to make all of the ingredients.
  • Dump dough onto a lightly floured surface and gently flatten out to a rectangle that is about 9 inches long and 5 inches wide. Fold the long sides over in thirds so that you now have a rectangle that is 3 inches long and 5 inches wide. Repeat process two more times. This is how you get the layers. Flatten the final rectangle so that its about an inch thick. Place inside a 9x13 baking dish and press down to expand the dough so that it covers the bottom of the dish.

To make the sausage:

  • Combine all sausage ingredients in a large bowl and mix well to combine. Cook over medium high heat in heavy bottom pan until brown and crumbly, about 10-15 minutes. 

To assemble the casserole:

  • Add about 1/3 of the cooked sausage to the top of the bisuit dough. Cover with grated cheese.

To make the gravy:

  • While the casserole is cooking, make the gravy. In the same pan you cooked the sausage, combine the remaining 2/3 quantity of sausage with the butter over medium high heat. Once the butter has melted, sprinkle sausage with flour, stir, and allow to cook for several minutes.

I highly recommend making your own flaky buttermilk biscuit dough from scratch, but you can always substitute with 16-ounces of biscuit dough in a tube.
