I’ve decided from this point on a vegan breakfast casserole is the best way to welcome rising guests.
A traditional breakfast casserole includes layers like biscuits, sausage, scrambled eggs, and cheese. However, it was so easy to make the layers in this breakfast casserole vegan.

How to Make Vegan Breakfast Casserole
Here is a summary of the steps to make this tasty dish. See the recipe card below for more detailed instructions (with step-by-step photos).
- Make the biscuits homemade or use store-bought biscuits.
- Lay biscuits or press homemade biscuit dough into the bottom of a prepared pan.
- Prepare the tofu scramble.
- Cook the vegan sausage and spread them out over the sausage layer.
- Top with tofu scramble, spreading it evenly over the dish.
- Are you adding potatoes? If so, sprinkle them evenly over the tofu layer.
- Top with vegan cheese shreds. See more on the ways to melt vegan cheese.
- Cover with foil and bake until the cheese has melted and the biscuit layer is done.
- Remove the foil and bake for a few more minutes, to get a crispy golden crust around the edges.
I am fascinated with the idea of making perfect biscuits. This article by Joe Sevier about The Fluffiest Biscuits Ever has some great advice on doing just that.
To make the breakfast casserole gluten-free, substitute all-purpose flour with gluten-free baking flour.
Don’t want to use tofu scramble? Look at this vegan frittata with Just Egg. It’s a great example of how you can make vegan scramble without tofu.
Quick Fix Tip
You can skip making the vegan biscuit from scratch and use a 16-ounce can of store-bought biscuits. See these Accidentally Vegan Products for vegan biscuits to buy. There are eight biscuits in a can. Cut the biscuits into quarters and layer them in the bottom of the pan. This is a great time saver!
Sometimes vegan cheese may take a little bit more heat to melt. If so, turn up the oven temperature by 15 degrees for the last 5 minutes to coax that vegan cheese to melt.
When making breakfast, you don’t want to spend the entire day in the kitchen. This is especially true if you have family in town (Unless they’re that kind of family, then, by all means, tell them the recipe takes lots of time… Wink, wink).
Casseroles are a great way of making an easy meal because you put everything into one dish and bake it all together.
If you’ve got a big gathering in the morning, you can make this dish the night before. Here’s how:
- Make this casserole the night before by compiling all the ingredients into your prepared casserole dish.
- Cover and refrigerate overnight.
- In the morning, turn on the oven and remove the casserole from the fridge and let it sit while the oven preheats.
- Bake the casserole as suggested.
Breakfast Casserole Flavor Options
When it comes to this casserole, you’ve got options for what you put inside it. I’m more of a maximalist when it comes to flavor, so I say add it all! Play around with these flavor option ideas until you find your favorite mix.
- Tater Tots — Add rows of tater tots on top of the tofu scramble then top with cheese before baking.
- Green onion — Remove the stem ends from 3 or 4 green onions and then chop up the rest. Add the chopped green onions over the tofu scramble.
- Gravy — Serve this easy vegan gravy on the side to create a “biscuits and gravy” vibe to your morning.
- Vegan Hashbrown Casserole — Add frozen shredded hash browns as a layer in this scramble. I prefer hash browns on top so they’re get crispy in the oven.
- Just Egg — Tofu scramble only takes minutes to make, but if you prefer an alternative, then cook up some scrambled Just Egg and use it in place of the tofu.
- Veggie Bacon — You can substitute the veggie sausage with veggie bacon. Or add veggie bacon with veggie sausage for a “supreme” type flavor combination. Use store-bought veggie bacon or this smoky vegan tempeh bacon.
Can I Add Hash Browns?
If you’d like to transform this into a vegan hash brown casserole, let me just say, I get you. Potatoes are always a welcome addition around here! Add a layer of air fryer potatoes in between the sausage and tofu scramble.
What Makes this Casserole Vegan?
By using plant-based ingredients, you can make any casserole vegan. For example, you can use vegan cheddar shreds, tofu scramble, and vegan sausage crumbles for a vegan breakfast casserole.

Vegan Breakfast Casserole
- 2 cups flour
- 4 teaspoons baking powder

- 1 teaspoon salt
- ½ cup vegan butter sliced
- ⅔ cup vegan buttermilk
- Heat your oven to 400°F. Prepare a 9×13 baking dish by spraying with vegetable spray.
For the Biscuit Layer
- (See my note on using store-bought biscuits). In a food processor combine the flour, baking powder, baking soda, and salt. Pulse for a second or two to combine.
- Next, add the sliced vegan butter and soy buttermilk. Pulse again for several seconds to allow the mixture to combine. If it's too crumbly, add a tablespoon or two more of plant-based milk.
- Press the biscuit mixture into the bottom of the pan. You don't have to worry if there are bits of flour here and there. Just make sure it's evenly distributed across the bottom.
- Prepare the Easy Scrambled Tofu according to the recipe linked above.
- While you're waiting for the Scrambled Tofu to cook, spread the veggie sausage crumbles evenly over the top of the biscuit layer.
- Optional: Add a layer of hashbrowns
- Spread the finished Scrambled Tofu evenly over the top of the sausage crumbles.
- Top with shredded vegan cheese.
- Place your dish in the oven and bake for 30 minutes, until the biscuit layer appears done and the cheese is melted. Tip: Sometimes vegan cheese may take a little bit more heat to melt. If so, turn the oven up to 425°F for the last 5 minutes to coax that vegan cheese to melt.
- Remove from the oven to cool. Serve warm.

Vegan Sausage Options
- Homemade — Add my sausage spice mix to store-bought veggie crumbles, diced sweet potatoes, quinoa, etc.
- Gimme Lean Veggie Sausage — buy it at health food stores or some national grocery store chains. It’s soft right out of the package, so you should sauté it in a skillet before sprinkling it over the biscuit layer.
- Field Roast makes vegan sausage links, which can be broken into pieces and used in this recipe.
- Vegan Breakfast Sausage Patties — make your own at home with simple ingredients.
Biscuit LayerYou can skip making the vegan biscuits layer and use a 16-ounce can of store-bought biscuits. See my Accidentally Vegan Products for vegan biscuits you can buy. There will be 8 biscuits in a can. Cut the biscuits into quarters and then layer them in the bottom of the pan. This is a great time saver!
