This Vegan Mexican Egg Casserole gets a delicious Mexican flair with layers of roasted potatoes, onion and bell peppers, spinach, tomatoes, vegan cheese, and fluffy tofu eggs seasoned with taco spice. Your whole family will gobble this easy brunch recipe up! Nut-free + gluten-free option.
I love me a good breakfast casserole and today we are adding a Mexican twist to it!
This easy Vegan Mexican Casserole is my new favorite weekend brunch recipe. I guess you could call it Mexican Egg Casserole or Mexican Egg Bake. Essentially, it is vegan tofu eggs mixed with some pre-baked veggies, some bread, and some vegan cheese shreds then all baked in a casserole dish. It is almost like a vegan egg souffle dish packed with vegetables. You can also add in some cooked beans if you like to make it even more hearty.
Now let’s talk about the seasonings because that is where we get the Mexican flavors in. Taco seasoning and chipotle chili powder are your best friends for whenever you want to add a pinch of fiesta to any dish.
I make my own taco spice using this taco seasoning recipe but storebought is fine as well. Making your own is quick and easy and takes mere minutes using common spices you probably already have, so it’s worth checking out the recipe. When made at home, you can also adjust the flavor and heat to preference.
Back to the vegan Mexican casserole – we use a mix of pre-roasted veggies and veggies as add ons. Pre-roasting the potatoes, onion and bell peppers before adding to vegan tofu “egg” mixture is necessary to allow for them to cook. And we all love that aroma of roasted bell peppers and charred onions, don’t we? It makes this vegan egg casserole taste a bit like fajitas.

Notes
Nutrition
Ingredients:
- any breakfast casserole needs potatoes – I use Yukon gold potato here.
- onion and red bell pepper are great here and will be roasted along with the potatoes. If you don’t like onion, skip them and add some onion powder, if wanted.
- later on, we add fresh spinach and tomatoes or salsa – those don’t have to bake
- Cubed day-old slices of bread or toast add some texture! And yes, it NEEDS to be toasted!
- Chipotle pepper flakes and taco seasoning bring on the Mexican flair
- the base of our vegan egg mixture is blended soft or firm tofu
- flour is added to thicken the egg mix while baking
- turmeric for that golden egg color
- I like to use a mix of salt and Indian Sulfur Salt (kala namak) to get that eggy taste into the egg sauce. Sulfur salt smells pretty intense, similar to hard-boiled eggs. If that sounds a bit scary to you, feel free to skip it but I recommend you try it.
- apart from salt and pepper we also add some ground mustard and taco seasoning to the eggs for some more oomph
- in traditional egg casseroles, the eggs make the casserole rise. Here we use baking powder for the same effect.
Tips:
- You want to make sure your potatoes are cubed small and evenly.
- For gluten-free use gluten-free bread and cornstarch or gluten-free flour for thickening
- Make sure your sandwich bread is vegan. Some have eggs or milk powder added. At the bottom of the nutrition information, it will say if it contains eggs or dairy.
- Want the casserole extra? Add some vegan cheese shreds to to the tofu egg mix as well
- Vegan sausage would be another great addition. If you plan to use vegan sausage or chorizo, add it to the potato mixture so that it gets golden brown, and then add in your egg mixture.

This has been on my “make this week” list for over 19 months!!! (I think I might have to retitle that list). I’ll be making it again much sooner. It was very tasty, quick, easy and used ingredients I normally have on hand. Another winner and big thank you to you, Richa, for your hard work and always-delicious recipes.
Vegan Richa Support
yay! so glad you finally made it and will again!
Carol Murphy
I’m going to try this recipe as it looks great! I’m wondering if you ever tried this in muffin cups to make individual quiches?
Vegan Richa Support
I have not tried but it sounds interesting. Please let us know your thoughts if you give this a try!
Jen
I was wondering if you think I could substitute okara for the tofu. I make soymilk frequently and have a lot of leftover soy pulp (which I use to make vegan biscotti and also vegan cheeses). However, I would like to find additional uses for it. Any opinions?
Richa
I haven’t tried it. Make a small portion to check
Emily
Yum! Your taco seasoning blend is my favorite homemade mix. The best part are the crispy, browned edges of the casserole. I’m stealing another reviewer’s idea of making burritos with the leftovers for easy lunch to-go!
Vegan Richa Support
Love it!
Michelle
If I want to make this for a larger group and use a 9×13 casserole dish, would I double everything including the tofu? Or just use the same amount of tofu and double everything else?
Vegan Richa Support
goign from 9×9 to 9×13 – doubling will be too much…. you could do another 1/2 recipe
Sheena Verma
I loved the recipe, thank you Richa, it was amazing. Only modifications I made were: I put broccoli instead of spinach because I had it on hand, I omitted taco seasoning because I didn’t have any, and I used “real” shredded cheddar cheese on top because I’m vegetarian, not vegan.
Richa
Awesomec
Nancy
This looks fantastic! Do you have any thoughts on putting it in the fridge after combining everything and baking the next morning?
Vegan Richa Support
thanks, you could do that – but it would be even better if you kept all the veggies in the dish, covered and the ‘egg’ mixture separate and combined when ready to bake. but either way will work just fine.
Belvy
Yum! I used an anaheim (and an orange) pepper to go with the Mexican flair. Breakfast for dinner! Could even be for company.
Vegan Richa Support
mmmmmmm Ole!
Jessica
So good!
I added 1/2 of a Trader Joe’s soy chorizo to it and 1 can of rinsed/drained black beans. It was perfectly spicy for us.
I’m not sure where I went wrong, but I ended up with enough that I had to bump up to a 9x11pan. (That’s ok-lots of leftovers for tomorrow!)
I missed the step about blending the tofu, so mine turned out to be more of a crumbly-style scramble but it’s still really good! We just rolled it up into breakfast burritos!
I will absolutely make this again.
Richa
Ooh great idea for baked scramble casserole version ! Yes the volume of the beans and soyrizo would need a bigger pan
Bev
Delicious!!! The flavors are fantastic—all the way through!
Mine turned out watery, though. Probably because I used silken tofu instead of a block of tofu. I suppose it could be used with more thickener (flour or cornstarch) added.
I served it with (homemade) vegan sour cream, avocado and cilantro.
I’ll be making this again and again!
Richa
Yes, I usually use firm tofu. Or the one that says medium firm . Silken is way too soft and high moisture. You can add 2 tsp more flour to help it set. Bake a few minutes longer as well
Diana
I saw this last night and had to try it this morning since I had all the ingredients. Recipe was a bit involved because I made your taco seasoning and made homemade salsa for this. About 5 minutes before it was done, I added more salsa on top and sprinkled cheddar cheese on top. Next time I will try it with the diced tomato in the tofu mix and continue to add the salsa on top with the cheese. Thank you for this recipe! I will definitely be making this again and again.
Richa
Awesome! Yes prep those before
Barbara
This looks delicious and exactly what I need to take to work for morning snack! I am very new to cooking with tofu and wonder does it have to be drained?
Vegan Richa Support
yay! yes, you do need to drain it
