A flavorful make-ahead breakfast casserole is the best way to welcome family and friends to a celebratory morning gathering. By prepping ahead, all you have to do is pop the casserole in the oven until cooked through. It’s a perfect time-saver and allows you to mingle with your guests when they arrive, especially if you have not seen them for quite a while.
This overnight breakfast casserole is fluffy, full of veggies and spice if you decide to include serrano peppers and a spicy sausage. Those ingredients can be replaced with more mild ingredients without compromising flavor. Ingredients such as a non-spicy sausage or bell pepper will do the trick. What gives this fancy breakfast its unique flavor is the addition of Maille Dijon Original Mustard to the mix.
The result is a delicious, family-style meal everyone can enjoy for the holidays. It not only tastes amazing but any leftovers can be kept well for a few days in the refrigerator. It also travels well if transporting to a potluck type of gathering. The colorful, texture-rich contribution to the party will wow the guests and keep them asking for seconds and thirds.
