This vegan breakfast casserole is perfect for brunch, holidays with family, and even weekly meal prep! With the best vegan "egg" mixture you've ever tasted, hearty sourdough, veggies, plant-based sausage, and melted cheese. Customize it with different veggies, spices (think Italian or Tex-Mex), and vegan meat alternatives. See the Notes section for oil-free and gluten-free options.
3tablespoonsflour - such as all-purpose, a GF blend, rice, or whole wheat
Other ingredients:
10ouncessourdough bread, cut or torn into large bite-size pieces - about half of a boule
4servingsvegan sausage, chopped and/or crumbled - choose any flavor you'd like in the casserole (Italian, spicy, breakfast sausage, etc)
1largered bell pepper, seeded and chopped
½cupchopped green onion
3 ouncesfresh baby spinach
7ouncesmild, shredded vegan cheese such as mozzarella or cheddar - I used Chao Original; Tip: if the shreds are long, chop to help with melting
Instructions
Preheat the oven to 350°F and lightly oil a 13 x 9-inch baking dish.
In a blender combine all of the tofu "egg" ingredients EXCEPT flour. Slowly increase speed, and blend until smooth. The mixture will be very thick; stop to stir as needed. Taste for seasoning. Add the flour and blend again for a few seconds to incorporate. Set aside.
Preheat a saute pan over medium heat, and cook the sausage for about 2 minutes or until starting to brown. Add the bell pepper and green onion and cook for another 1 to 2 minutes.
Refer to step-by-step photos above if needed. Arrange bread in a single layer in the casserole dish, followed by spinach and the sausage mixture. Sprinkle with a handful of cheese, if desired.
Pour the tofu mixture on top, using a spoon or spatula to remove as much as possible from the blender. Carefully stir to incorporate the ingredients and coat everything with tofu. If there's any messy tofu "egg" on the sides of the dish, wipe it off so it won't burn during baking.
Bake uncovered for 30 minutes. Sprinkle the remaining cheese on top, cover tightly with foil (careful—it's hot!), and bake for another 25 to 30 minutes or until the cheese is melted and the center of the casserole is hot.
Let the covered dish rest for 10 minutes. This gives the cheese more time to melt and helps the casserole set before slicing. Serve hot.

Notes
Oil-free - replace the store-bought vegan sausage with a homemade seitan sausage, seasoned beans, or tempeh bacon. And instead of store-bought vegan shreds, add dollops of this easy vegan mozzarella on top!Gluten-free - choose a thick and sturdy gluten-free bread or replace the bread with 2 packages of frozen hash browns. Thaw the hash browns before adding to the dish. Also be sure to use a gluten-free flour blend (I used King Arthur GF 1:1 during recipe testing).Make ahead: to prep it the night before, assemble through Step 5, cover and refrigerate overnight. In the morning, since the entire dish will be cold, add 5–10 minutes to the bake time.Store leftover breakfast casserole in the refrigerator for up to 5 days. It reheats best in the microwave. Or freeze for up to one month.
