Ingredients
  

  • 16 ounces Ground Breakfast Sausage (diced links work too)
  • 1 Tablespoon Dried Rosemary
  • 1 teaspoon Dried Sage
  • 1 teaspoon Dried Thyme
  • 1/4 teaspoon Salt
  • 1 Tablespoon Flour
  • 2 Cups Milk
  • 5 Slices Sourdough Bread, cubed (Approx. 10 ounces or 6 cups)
  • 2 Cups Shredded Fontina Cheese (Approx. 6 ounces)
  • 5 Eggs, beaten
  • 2 Tablespoons Butter

Instructions
 

  • Use one tablespoon of softened butter to grease a 2 quart glass casserole dish.
  • Place cubed sourdough bread in the buttered dish and set aside.
  • In a medium saucepan, melt one tablespoon of butter over medium-low heat, add ground sausage.
  • When the sausage begins to brown, sprinkle the rosemary, sage, thyme, salt, and flour over the meat. Mix in the herbs and flour while breaking up the meat with a spatula.
  • Let the meat, herbs, and flour cook on medium to low heat for two minutes.
  • Add the milk and mix well. Continue to cook on medium to low heat, stirring occasionally, until the milk begins to steam. (Do not allow the milk to boil)
  • Once the milk is steaming, add the shredded cheese 1/4 cup at a time, making sure all of the cheese is melted before adding more.
  • After all the cheese is incorporated, remove from heat and let the sauce cool until it's no longer hot to the touch.
  • Whisk in the beaten eggs until thoroughly combined.
  • Pour the mixture over the top of the bread.
  • Use a spatula or knife to lift some of the bread so the liquid can reach the bottom, while pushing some of the sausage to the lower layers.
  • Cover tightly with foil or plastic wrap and refrigerate overnight.
  • In the morning, take the casserole out of the fridge about 30 minutes before you're ready to put it in the oven.
  • Preheat the oven to 350 degrees Fahrenheit.
  • Bake the breakfast casserole uncovered for 45 minutes, or until the internal temperature reaches 160 degrees Fahrenheit, or a knife inserted in the middle comes out clean.
  • Let the dish cool for about 5-10 minutes before slicing to serve.
