Vegetarian overnight breakfast casserole with morning star farms grillers crumbles.

My husband and I may not be vegetarians ourselves, but we have friends and family that are.

When we have guests, we try and accommodate all of their diets. We don’t want anyone to not be able to enjoy the food that we serve. That is why we believe that it is important to have vegetarian options to offer our guests, especially during the holidays.

This cheesy vegetarian overnight breakfast casserole is perfect for serving Thanksgiving morning, Christmas morning, New Year’s day, or anytime over the holidays that you are hosting overnight guests. We like to serve it up along with overnight French toast casserole (my favorite) and this hearty farmer’s breakfast casserole for the meat-eaters.

The casserole is quick and easy to prepare, and perfect for feeding a crowd.

The best part about this delicious recipe is that it can be enjoyed not only by vegetarians, but by everyone. MorningStar Farms® Grillers® Crumbles™ are the perfect addition to this recipe, giving it a great flavor that everyone is sure to love.

This vegetarian breakfast casserole can be prepared the night before, then refrigerated overnight. In the morning it just needs to be baked for about an hour and then it is ready to serve. It truly is the perfect breakfast to serve overnight guests on busy holiday mornings.

I like to pop the breakfast casserole in the oven as soon as I wake up, and then go ahead and get ready for my day. The casserole is ready to serve by the time the rest of the house is up and ready for breakfast.
