This breakfast casserole recipe is one of our family favorite recipes we use for a number of occasions.  It’s so great for having guests over.  We love making it for Holidays too!  It’s so great for Christmas morning because you can prepare the recipe a couple days in advance and keep in the refrigerator.  You’ve got lots of options with this recipe and I think you’ll love it just as much as we do!

Easy Breakfast Casserole

With just a little prep work, you’ll find this an easy breakfast casserole.  Slice your French Bread into 1 inch slices, then into 1 inch pieces.  Place into a lightly greased 9 x 13 inch baking dish.  I love the Emile Henry brand you can get at your favorite kitchen stores.  I believe I got mine from Williams Sonoma.

You’ll place your cooked sausage over the French Bread pieces then start to prepare the egg mixture that gets poured over the breakfast casserole.  It’s best to use a large mixing bowl.

Once you’ve added your seasonings and pesto to the eggs, whisk until well beaten.  Pour over bread and sausage layer.

Remove breakfast casserole from oven and garnish with finely sliced fresh basil.  Let cool for about 5 minutes then cut into squares and serve.

How To Serve Casserole

The great thing about this recipe is you can serve it as is or serve with a nice fruit plate to share.  You can also have some sweet breakfast dishes to pair with this savory dish.  Pancakes go great with this casserole, even waffles.  Get creative.  Have fun and enjoy!


Prepare this recipe a couple days before actually serving.  Cover tightly with foil and keep in refrigerator.  Remember to take out of refrigerator a couple hours before ready to bake if possible.  Having the dish more room temperature will keep cook time the same as recipe states.  If dish comes right out of the refrigerator to the oven, you may need to bake longer.
