Not only is my Overnight Breakfast Casserole easy and tasty, it’s also very versatile! You can change it up by using ham or sausage instead of bacon. You could also use Pepper Jack or another favorite cheese instead of Cheddar. You could stir some veggies into the eggs, like spinach or a small can of green chilies. There are so many possibilities! Obviously if you change the meat or cheese, the nutrition information and WW points may change as well. Make it my way or make it your own!

Overnight Breakfast Casserole

This easy Overnight Breakfast Casserole is perfect for weekends or Christmas morning. Prep it the night before and in the morning, just bake!


  • 6 slices center cut bacon
  • 9 slices light bread, cubed (I used Pepperidge Farm light style oatmeal bread)
  • 3 ounces 50% reduced fat sharp cheddar cheese, shredded (I use Cabot cheese)
  • 8 large eggs
  • 3 1/2 cups skim milk
  • 1 1/4 teaspoons dry mustard powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper


  • Cook the bacon according to package directions. Allow to drain on paper towels and then chop or crumble into smaller pieces.
  • Mist a 9x13 baking dish with cooking spray. Spread the bread cubes across the surface of the dish and sprinkle the shredded cheese evenly across the bread cubes. In a large mixing bowl, whisk together the eggs, milk, mustard powder, salt and pepper until combined and smooth. Pour the egg mixture over the bread and cheese. Sprinkle with the crumbled bacon. Cover with plastic cling wrap or aluminum foil and refrigerate overnight.
  • In the morning, remove the casserole from the refrigerator 30 minutes before you plan to bake. Preheat the oven to 350 degrees.
  • Uncover the casserole and bake for 50-60 minutes or until the casserole seems mostly set and a toothpick inserted in the center comes out clean. Let stand for 10 minutes before cutting to serve. Cut into 8 pieces.

  1. Is this dish freezer friendly? 

  2. This is going to be our Christmas Breakfast for the family – hope its good 🙂

  3. Sounds delish. The mustard powder is an ingredient that I have forgotten all about. Can’t wait to try this.

  4. What is sodium content per serving for breakfast casserole.

  5. I wonder if it would taste good with Almond Milk. it may save a point or two. What do you think? PS. Love your recipes! 

  6. We did not like this at all. Very bland and took way longer to bake in the oven. Sorry 

  7. Made this last night and baked it for my family this morning! Added mushrooms, a red pepper and an onion. Turned out great! Thanks for sharing!5 stars
