It’s never too late to enjoy a relaxing vacation with your family or guests, even though Christmas is over! One way to serve breakfast is to make the always-popular Overnight Breakfast Casserole, which comes in so many varieties. I’ve posted several here on RE, one with Italian sausage, one in the slow-cooker, one with kale and sausage, and one with pears. Yes, sweet pears!

Another lovely way to think of others is to exchange a breakfast casserole with a friend, for either their own favorite recipe, or better yet, a pan of Cinnamon Rolls.

Our friends who own the brand new NW Raw, a 100% natural cold-pressed juice bar in Ashland, Oregon, make the best cinnamon rolls you’ll ever indulge in. They’re made with all organic ingredients, and topped with a salted-caramel frosting. No calories, right? Wrong. But seriously, if you’re going to take the plunge, they really have to be top notch. Gooey, flavorful, moist, and the kind that melt in your mouth.

I’m drooling as I type.

So my friend and I exchanged. One 9×13 for another. Breakfast casserole for a pan of cinnamon rolls, to enjoy with our families on Christmas morn! It could be an annual tradition or just an occasional, fun thing to do.

This year I made Recipe Girl’s delicious recipe, and also made one for ourselves. I used Organic Sausage, which I sautéed up ahead of time. Yummy! (Look for Lori’s book at your local Target!)

Then added all the other yummy ingredients, sealed with foil, and popped in the fridge overnight!

It truly is a melt-in-your-mouth casserole.

One thing easy about overnight casseroles is that they are easy to double up and make 2 pans’ worth, for either a large breakfast party, or to share with another family!
