There is something special about waking up on Christmas morning and enjoying a delicious meal with your family and loved ones. Breakfast on Christmas morning has always been such a wonderful memory from my childhood. My brother and I would wake up super early, peek at the gifts, then wake our parents up to open them. Afterward, we’d sit down for the best meal of the year.

strata ingredients

Ever since I was a little kid, we would enjoy breakfast strata on Christmas morning. Not only is strata super delicious, but it’s also designed to be prepped the night before and popped in the oven for an hour in the morning (while we opened gifts), and then it’s ready to enjoy! After all, who wants to prepare a huge breakfast on Christmas morning?  As you’ll see below, the batter for our vegan strata needs to soak into the bread for 8-12 hours to set fully, so it’s perfect for making on Christmas Eve.

If you’re unfamiliar with strata, it’s a layered casserole dish, similar to quiche, traditionally made with eggs, meat, cheese, and bread. For our veganized version, we replaced the eggs with a chickpea flour batter, the cheese with dairy-free vegan cheese, and the meat with vegan beef crumbles. We also added some veggies to make it a little “healthier” ?. The key is getting a nice absorbent loaf of Italian bread to soak up all the batter. We are so excited for you to try this vegan strata– it’s very close to my heart, and the final product is incredibly tasty. Enjoy!

Vegan Strata | Make-Ahead Holiday Breakfast Casserole

  • Author: Sweet Simple Vegan
  • Total Time: 9 hours 30 minutes
  • Yield: 8 servings


The perfect breakfast for Christmas morning? This vegan strata aka a make-ahead breakfast casserole that is easy to make and incredibly tasty!


  • 1/2 cup vegetable broth or water, to sauté with
  • 1 cup finely chopped onion
  • 1 cup finely chopped celery
  • 4 oz. mushrooms, cleaned and thinly sliced
  • 14 oz. vegan sausage (we use Impossible sausage grounds)
  • 1 tablespoon German mustard
  • 2 cups spinach
  • ~2 cups vegan mozzarella shreds
  • ~5 cups diced sourdough bread

Egg batter*

  • 1 1/2 cups chickpea (garbanzo bean) flour
  • 3 cups unsweetened almond milk
  • 2 tablespoons flaxseed meal
  • 2 tablespoons nutritional yeast
  • 1 teaspoon salt
  • 1 teaspoon turmeric
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon black salt
  • A few dashes of nutmeg


  • 24 oz Just Egg or similar liquid egg substitute

Garnish with:

  • Green onion, thinly sliced
  • Fresh parsley, roughly small


  1. Grease a deep 9″ baking dish and set it aside.
  2. In a medium pan over medium heat, add in 1/4 cup of vegetable broth. Once heated, add the onions, celery, and mushrooms and sauté until the onions are translucent and fragrant, or about 3-4 minutes. Once cooked, add in the vegan sausage and crumble it in with a wooden spoon or fork. Sauté for about 3 minutes or until the sausage is cooked through, being sure to add vegetable broth as needed to prevent burning. Once cooked, remove from heat and add in the mustard and spinach. Mix until uniform and set aside.
  3. In a medium bowl, whisk together all of the ingredients for the egg mixture until smooth. (skip this step if using Just Egg or similar)
  4. Into the greased baking dish, layer in the sausage mixture, bread cubes, egg mixture, and cheese into the baking dish. Mix the layers together as you go so that they are uniform throughout the dish and continue until all of the ingredients have been used. Cover and set in the refrigerator overnight (or at least 8 hours).
  5. Remove from the refrigerator and place into the oven at 350°F for 1 hour.
  6. Cool completely before serving and garnish with fresh parsley and green onions


  • You can substitute the egg batter with 24oz of Just Egg or any other liquid egg substitute.

  1. To make ahead… do we prepare the night before and only bake in the morning? Or bake ahead of time and reheat in the morning?

    1. We had an error in the recipe, my apologies! One step was missing: set in the refrigerator overnight then bake in the morning! 🙂

  2. I do not have any black salt (I accidentally sent it to my school address instead of my home address. I will be trying it out without it I guess!

  3. This looks delicious! I bet this is the perfect way to use up any leftover bread and veggies from the night before! Also, I adore how Caitlin’s recipe is more sweet and yours is more savory. Adds a great mix to different kinds of palettes!

  4. I love the idea of preparing this ahead and then just warming it up the following morning! Such a time saver especially on Christmas morning!

  5. This recipe looks stunning. I’m more of a sweet breakfast kind of girl (that’s the habit in many European countries) but I will definitely make this during the holidays as a meal ♥ thank you for the discovery!
