Equipment

Ingredients

  • 6-8 slices plain white sandwich bread
  • butter very soft, for buttering bread
  • 2 cups Jack cheese, shredded not pre-shredded from a bag
  • 2 cups cheddar cheese, shredded not pre-shredded from a bag
  • 12 ounces pork sausage crumbled and browned (I use Jimmy Dean)
  • 1 4-ounce can green chiles
  • 6 eggs large
  • 2 cups milk
  • 1 teaspoon kosher salt
  • ½ teaspoon paprika
  • 1 teaspoon oregano
  • ½ teaspoon black pepper
  • ¼ teaspoon garlic powder
  • ¼ teaspoon dry mustard
US Customary - Metric

Instructions

  • Start by removing the crusts from your bread and lightly buttering one side.
  • Place bread, butter side down, in a 9x13 baking dish. You want the bottom of the pan covered with no big gaps, so cut up some pieces like a puzzle to cover the whole pan.
  • Grate cheese and sprinkle evenly over bread. Then, layer on browned sausage, followed by green chiles.
  • In a medium sized mixing bowl, whisk eggs. Add milk and seasonings; combine well.  Give the mixture a final whisk before immediately pouring evenly on top of the assembled casserole.
  • Cover well and place in the refrigerator overnight.
  • In the morning preheat your oven to 350℉.  Bake (uncovered) for 50-60 minutes. You'll want the center to be puffed and set and the outside edges to be golden brown. Let cool for about 10 minutes before serving.

Notes

  • Store leftovers in an airtight container in the refrigerator and consume within 3-4 days for best results.
  • Reheating tip: Leftovers will reheat more evenly if you cut your piece of casserole into a few smaller pieces before popping in the microwave.
