This Make-Ahead Veggie Breakfast Casserole is loaded with veggies, cheese, and eggs. It’s very easy to make and is a perfect healthy breakfast for Christmas morning!
I love making casseroles like my Cauliflower Casserole Recipe and Zucchini Casserole Recipe because they’re so easy to make. So it wasn’t long before I tried to make a casserole but for breakfast instead!
Today, I share this make-ahead veggie breakfast casserole recipe that you will love it because it’s so D.E.L.I.C.I.O.U.S., and at the same time, it’s very versatile! You can use any fresh veggies you have in your fridge.
I used what I had available, such as red onions, broccoli, mushrooms, cherry tomatoes, and spinach. But if you don’t have one of these ingredients, you can still make it. You can add anything you please, such as sausage, chicken, bell peppers, cauliflower, and the list goes on and on.
Also, choose your favorite cheese. I added a mixture of cheddar cheese and mozzarella, but this recipe also goes really well with Swiss or even goat cheese. It’s totally up to you! If you avoid dairy, simply skip this ingredient. No problem at all. This breakfast is full of goodies for your health like fiber and protein, which makes it hearty and keeps you satisfied for hours. It always feels good to get those veggies in first thing in the morning, don’t you think?
I really think it would be an amazing recipe for Christmas morning breakfast for two reasons. First, it’s the perfect way to use leftovers from your holiday meals (I always have extra veggies because of my go-to Ground Beef Veggie Skillet Recipe and Roasted Parmesan Green Beans for dinner). Second, you’ll have free time to open your gifts, give presents, and enjoy the special Christmas morning since you can make it ahead and just bake it in the morning.
Believe me, this Make-Ahead Veggie Breakfast Casserole makes a great overnight casserole. Prepare everything the night before, such as chopping and sautéing the veggies. Then, pour the egg mixture over top, add the cheese, and then cover with foil. Refrigerate it overnight, and then bake it in the morning. It’s very good, gluten-free, and low-carb! This breakfast will absolutely make your Christmas morning merry and very special. Enjoy!
