Ingredients you will need

You can swap the ingredients and spices easily and feel free to adapt how you serve them using your favorite fajita fixing ingredients. See below for more inspiration!

For the sheet-pan vegan fajitas

Bell peppers: you will need 2 large bell peppers for this recipe. Feel free to choose any colors, such as red, orange, yellow or even green bell peppers.
Onion: a large yellow onion or a sweet onion, such as Vidalia, works well for making fajitas. A red onion would work too and add a little sweetness.
Garlic: I used 3 cloves of garlic, but add more if you like garlic flavor.
Tofu: you will need one block of tofu for this recipe. I used the extra firm tofu from the brand Wildwood.
Spices: I used a homemade fajita seasoning mix made out of chili powder, ground cumin, smoked paprika, garlic powder, onion powder, dried oregano and salt. You can also use the spices from the packaging of taco seasoning for this recipe.

To serve

Tortillas: I used these whole wheat flour tortillas for serving the fajitas. I like using the regular tortilla size, although large burrito tortillas are great for making burrito sandwiches too. Hard taco shells or corn tortillas would be great as well!
Romaine lettuce: for a nice crunch and some freshness.
Avocado: optional, but the creamy consistency works well in contrast with the other ingredients.
Sour cream: adds a nice cooling effect and some more creaminess. Use a store-bought vegan sour cream or make your own sour cream using silken tofu.
Salsa: I used a jar of store-bought mild salsa, which saved me some time. Most jarred salsas are super healthy and made without oil (just check for the amount of salt added). For a spicy recipe, you can try pairing it with this roasted mango habanero salsa!
Lime: to squeeze some zesty juice over the fajitas when serving, which enhances the flavors from the spices.

What type of tofu to choose for this recipe

Extra-firm tofu works better for this recipe since it has less moisture and will create a more chewy texture when cooked. It gives the baked tofu such a pleasant meaty texture!

If you only have firm tofu, then it is fine, although the tofu will be softer and might break up more easily.

Do not use soft tofu or it won't hold well after cooking.

How to make a sheet pan tofu fajitas recipe

This is such a quick and easy recipe you can make on busy weeknights. It is so convenient, everything goes on one pan!

Start by preheating the oven to 400º and line a baking sheet with parchment paper.

Prepare the tofu and the vegetables

Drain the water from the tofu packaging and then, wrap the block of tofu in a few layers of paper towel or a clean kitchen towel. Add a heavy object on top and let it rest until ready to use. You can also use a tofu press if you have one. Even just 5-10 minutes can make a difference!

Meanwhile, clean and slice the peppers and onions.

Bake in the oven

Transfer the sliced onion and peppers to the prepared baking sheet and add the crushed garlic.

Then, using your hands, break up the block of tofu into chunks. Add the tofu pieces to the baking sheet as well.

Sprinkle all the spices and dried herbs over the baking sheet and use your fingers to toss the ingredients so they are all covered with the spices.

Space everything out on the baking sheets and spray some oil over it (optional, can be made oil-free).

Bake in the oven for 15 minutes, then toss/flip, and bake for another 15-20 minutes or until golden brown.

Finish up and serve

Once done, I like to squeeze some lime juice over the sheet pan.

Heat up the tortillas and serve the fajita vegetables and tofu with your favorite fajita fixings.

Cooking tips

I like to spray some olive oil over the veggies and tofu to help them crisp and caramelize. But this is optional if you are following an oil-free diet!
The size of your tofu chunks matters: you do not want them too big so they fit better in the tortillas and they get more surface to be covered with the spices. On the other side, pieces that are too small will get crumbly and not as chewy. You can have a peek at my in-process pictures and video to have an idea of the size you should aim for.

Variations

Feel free to experiment and include different vegetables to bake, such as mushrooms, cauliflower, zucchini or even spinach.

If the vegetable is tender and does not require much cooking, such as spinach, then simply add them midway through cooking.

You can also use different spices depending on your preference or what you have. Try adding a dash or two of ground cayenne pepper or chipotle powder for some heat or swap the smoked paprika for regular paprika if you are not a fan of smoked flavors.

Storage tips and how to meal-prep ahead

Keep the leftover veggies and tofu in an airtight container in the fridge for up to 4 days. To reheat, use the oven for the best texture or the microwave, if in a pinch.

I haven't tried it, but I do not recommend freezing the leftovers as I think the texture will become mushy once thawed.

Meal prep tip

You can make this recipe ahead, especially if you like to prepare lunches to-go ahead of a busy week.

For the best texture, then I recommend combining the spices and slicing the veggies ahead, store them in containers and toss + bake the ingredients just when ready to eat. You can also bake it ahead and transfer it to a container, although this will give you tofu bites that are less crispy.

FAQs

Can I pan-fry instead of baking in the oven?

Yes, you can. In that case, I would work in batches starting by roasting the vegetables first with a little oil (without the spices) in a large skillet. When tender, transfer to a plate and cook the tofu until crispy in the same skillet. Then, add the veggies back to the pan with the tofu, add the garlic and spices and cook until combined and fragrant, about 4-5 more minutes.

How are fajitas usually served?

Traditional fajitas come served on a hot plate still sizzling with a side of warm tortillas and fresh ingredients to garnish. This is usually the way to serve them in restaurants!

Is this recipe gluten-free?

The fajita tofu and vegetables are completely gluten-free. If you are following a GF diet, then be sure to use GF tortilla bread when serving them!

Can I use frozen peppers?

Frozen vegetables work too, although they don't need as much cooking and will be softer then if using fresh veggies. Check on them after about 20 minutes or so.
