HOW TO MAKE CHRISTMAS BREAKFAST CASSEROLE:

  1. Cook the sausage and bacon off beforehand, and save 1 tablespoon of bacon grease.
  2. Place the bacon grease into a large skillet over medium heat. Add the onion and bell peppers, and stir to combine.
  3. Cook, stirring occasionally, until the veggies are softened, 8-10 minutes; take off the heat and set aside.
  4. Spray a 9×13 baking dish with cooking spray.
  5. Add the cubed bread into the bottom of the dish.
  6. Top with the cooked sausage.
  7. Add the peppers and onion mixture on top.
  8. Top with the bacon.
  9. Add the diced Velveeta on top.
  10. In a large bowl, whisk the eggs with the half and half, salt, and pepper. Pour this all over the top of the casserole. Gently press down on the top of the casserole so the bread starts soaking in the egg mixture.
  11. Cover and place in the fridge for at least 8 hours, or best overnight.
  12. Preheat the oven to 375°F. 
  13. Top the casserole with the shredded cheddar cheese. 
  14. Bake for 40 minutes or until a toothpick comes out clean with no wet egg in the center. You may need to cover the casserole with foil if it starts browning too much.
  15. Allow it to sit for 10 minutes before slicing and serving.

FREQUENTLY ASKED QUESTIONS ABOUT THIS RECIPE:

WHAT KIND OF BREAD IS THE BEST TO USE?

Crusty bread works best. It soaks up the egg mixture and holds its shape in the casserole.

All you really need to do is chop up some slices of bread and leave it on the counter for a few hours.

CAN THIS BE MADE AHEAD?

Absolutely! The beauty of this dish is you can prepare it on Christmas Eve, cover it with plastic wrap, and pop it in the oven the next day.

Your Christmas casserole will be ready to roll when you roll out of bed!
