  • 1 lb pork breakfast sausage
  • 1 medium onion diced
  • 8 large eggs
  • 2 cups shredded cheddar cheese
  • 2 cups whole milk
  • 1 tsp kosher salt
  • ½ tsp black pepper
  • 6 slices white bread cut into 1” cubes and toasted


  • Preheat the oven to 350F. Grease a 9x13 baking dish.
  • In a heavy skillet, cook the sausage with a little vegetable oil, breaking up the sausage with a spoon, until cooked and browned. Remove from the pan.
  • In the same skillet, cook the onion until translucent, about 4-5 minutes. Remove from the pan and set aside.
  • In a large mixing bowl, whisk together the eggs, ½ the cheese, milk, and seasoning until combined. Stir in the toasted bread, cooked sausage and onions. Pour into the prepared baking dish, top with the remaining cheese, cover, and refrigerate at least 8 hours or preferably overnight.
  • Let the casserole come to room temperature before baking for 40-50 minutes, uncovered, or until a cake tester comes out clean.
