I call this recipe Christmas Morning Casserole because it has become one of my family’s Christmas traditions. I started making this casserole several years ago and now I make it every Christmas morning. It’s gluten, dairy, and soy-free. This breakfast casserole is easily adapted to your family’s likes and preferred tastes. I make ours with mushrooms since, as you may remember from a previous recipe, Mini-Mushroom Pizzas, my family loves mushrooms. This breakfast recipe is a simple, overnight, egg casserole. I prepare it the night before. On Christmas morning I pop it in the oven, and while it’s baking, we open our presents.
Place a food thermometer in the center of your casserole. It’s finished when the thermometer reads 160 degrees Fahrenheit. If you don’t have a thermometer, place a small knife in the center of your casserole, and when it comes out clean, it’s done. Once baked, it can sit out for about 2 hours.
You can keep your prepared casserole up to 3-4 days in the refrigerator before baking it. Once you bake it, your casserole will last 3-4 days cover, or sealed in an airtight container in the refrigerator. You can freeze your casserole for up to 3 months in an airtight container.
To reheat your casserole, remove it from the refrigerator. Cover it with foil and heat it in the oven at 375 degrees for 25 minutes. Remove the foil and finish heating it uncovered for 5 more minutes. To reheat frozen casserole, thaw it in the refrigerator first, then reheat in the oven.
Sometimes your casserole may turn out runny. If this happens, it often depends on the type of vegetables you use in your casserole. Some vegetables, are higher in moisture and cause excess water when baking. Saute your vegetables first, before adding them to your casserole. This should prevent your casserole from becoming too runny.
I hope you enjoy this recipe for Christmas Morning Casserole. No matter what your Christmas traditions, I hope you have a wonderful Christmas and enjoy every minute of this blessed season.
