I don’t know about you, but the minute I see the first leaf change color in October, my mind is immediately in holiday planning mode. What am I going to be for Halloween? Where is Thanksgiving going to be? Who is in charge of the turkey? Who is making green bean casserole? Then it is immediately Christmas time.

Where are we spending Christmas Eve? What are we eating for Christmas dinner? Who’s name did I draw for secret Santa? Do you feel a little crazy reading this already? Me, too. LOL. One thing I do to help me manage the holiday craziness is planning ahead. I love the cooking and baking part of the holidays so I like to plan and prep my recipes in a way where they won’t cause me stress!

Easy Holiday Breakfast Idea

This Spicy Italian Sausage Egg Bake has been one of my go-to holiday breakfast meals for many reasons. Why?

  • You can make this healthy breakfast casserole the night before and just bake it in the oven the morning of your event. No last minute preparation required while guests are arriving.
  • There are many ways you can change up this recipe. If you don’t have peppers, use whatever veggies are in your fridge. The sky is the limit.
  • If you have to serve this spicy Italian sausage breakfast casserole gluten-free, remove the bread and replace it with sweet potatoes!
  • Need to make this dish vegetarian? Go ahead and skip the sausage and add sauteed mushrooms.

You see? there are so many reasons to love this breakfast casserole. Not only does it ease my mind to know that breakfast is cleaned up and ready to go in the morning, but my family absolutely loves this healthy breakfast casserole. It is the #1 most requested dish and has squeezed its way into our family tradition. I mean…the goat cheese and sun dried tomato combination is everyone’s favorite.

Step One: Bake and Prep your Veggies

Remember that you can choose whatever bread you would like as well whatever potatoes you desire! Roast

Step Two: Saute veggies and Prepare Your Breakfast Casserole

Sautee your onions, garlic, and peppers in a saute pan. It really gives your veggies an amazing flavor! Keep in mind that you can use your favorite veggies, too! Mushrooms, eggplant, and cauliflower would all be delicious in this healthy breakfast casserole!

Step Three: Crack those EGGS.

We loved oven baked eggs on Team Fit Foodie, so this Spicy Italian Sausage Breakfast Casserole is one of our favorites! You have two choices when it comes to WHEN you bake this casserole.

  1. You can crack your eggs over the casserole and bake immediately.
  2. Cover and place your casserole in the refrigerator overnight and crack eggs over your casserole in the morning and bake. This is my favorite way to prepare and bake this dish! I love that all the flavors soak into the sourdough bread. It’s SO tasty.

Step Four: Top with Goat Cheese + Enjoy

After you pull your breakfast casserole out of the oven, top it with goat cheese (or your favorite cheese) and enjoy! Sometimes we drizzle a little balsamic vinegarette over the top and sometimes we eat it as is! YUM.
