Equipment

  • 1 large mixing bowl
  • Measuring cups
  • 1 9x13 inch baking dish

Ingredients
  

  • 2 lbs Ground breakfast sausage (I typically use one hot and one medium)
  • 9 Eggs, room temperature
  • 3 cups Milk (regular milk or almond milk both work fine)
  • 9 Slices of white bread, crusts removed & cut into 1″ cubes
  • 1.5 cups Shredded sharp cheddar cheese
  • 1.5 tsp Ground mustard
  • 1 tsp Salt
  • Pepper to taste

Instructions
 

  • Preheat the oven to 350 degrees. Brown the sausage in a large skillet over medium-high heat, drain, and set aside. In a large bowl, whisk the eggs, ground mustard, salt, and pepper. Add the milk, cheese, and sausage to the bowl and mix together. Add the bread last and stir in just to combine. Pour the egg mixture into a 9 × 13 casserole dish, greased with cooking spray. Bake for 50-60 minutes or until a toothpick comes out clean and it’s not jiggly in the center. Easy peasy!

Notes

I spray my casserole dish with olive oil using my oil sprayer. I love this thing!
