Fajitas are traditionally made with grilled meat, onions, and bell peppers, all served in warm tortillas. For this version, I've used tofu instead, cooking it in a skillet until golden and slightly crispy so it soaks up all the spices and lime juice from the spices and lime juice. It's a simple swap that keeps everything you love about fajitas while making them completely plant-based. Cooking the tofu first helps it get golden, slightly crispy, and full of flavor.

They're perfect for a quick lunch or dinner and also work really well for meal prep. You can make the filling ahead of time, store it in the fridge, and just reheat it when you're ready to eat. Serve it with warm tortillas and your favorite toppings for an easy, delicious meal any day of the week.

Why You'll Love These Tofu Fajitas

There are so many reasons to make this recipe, but here are some of my favorites:

So flavorful: The combination of spices and lime juice makes every bite bold and delicious.
Golden on the outside, tender on the inside: Cooking the tofu in a skillet gives it a nice golden texture while keeping it soft in the center.
Quick and easy: Ready in about 30 minutes with simple steps and no complicated techniques.

Great for meal prep: You can make the filling ahead of time and reheat it for an easy lunch or dinner.

Tofu Fajitas Ingredients

Tofu: Extra-firm or firm tofu works best because it holds its shape and gets nicely golden in the pan. Avoid soft or silken tofu, as it will fall apart. Pressing the tofu is not strictly necessary, but it's recommended because it helps remove excess moisture so it browns better and absorbs more flavor. For more details, check out my How to Press Tofu guide.
Olive oil: I like to use olive oil, but any oil will work. For an oil-free version, you can cook everything with a splash of water or vegetable broth instead.
Onion: I used yellow onion, but red or white onion will also work just fine.
Bell peppers: Use any color you like. I usually go for a mix for more color, but one or two types work great too.
Spices: Chili powder, cumin, smoked paprika, garlic powder, salt, and black pepper give these fajitas their classic flavor. Adjust the chili powder to taste depending on how mild or bold you like it. For a spicier version, add a pinch of cayenne pepper or red pepper flakes. You can also make your own using my chili powder recipe.
Lime juice: Adds freshness and really brings all the flavors together. Lemon juice works as a substitute if needed.

How to Make Tofu Fajitas

Press the tofu for 10-15 minutes (optional but recommended), then cut it into strips.

Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add the tofu and cook until golden on all sides. Remove and set aside.

Reduce the heat to medium-low, return the tofu to the skillet, and add the spices. Stir well for 1-2 minutes until coated and fragrant, then remove from the heat and set aside.

Tips for the Best Results

Don't overcrowd the pan: Cook the tofu in a single layer so it browns properly instead of steaming.
Cook the tofu first: This helps it get golden and keeps it from becoming too soft when you add it back to the pan.
Slice everything evenly: Cutting the tofu and vegetables into similar sizes helps them cook at the same rate.
Use medium-high heat: This allows the veggies to get slightly charred while staying tender and not soggy.
Add lime juice at the end: It keeps the flavor fresh and bright instead of cooking it away.

Serving Suggestions

The most popular way to enjoy them is in warm flour or corn tortillas with your favorite toppings. You can set everything out and let everyone build their own, which makes it a fun and easy option for any meal. Some of my favorite toppings are avocado, salsa, and a drizzle of vegan sour cream.

You can also serve them with a side of guacamole dip, beans, or even some tortilla chips to make the meal more filling. If you want something fresh on the side, a simple salad or some pico de gallo works really well too.

Another option is to skip the tortillas and serve the fajita filling in a bowl with your favorite toppings. It's just as flavorful and works especially well for meal prep or a quick weeknight dinner.

How to Store and Reheat Leftovers

Refrigerator: Store the leftover tofu fajitas in an airtight container in the fridge for up to 4 days. Let them cool completely before storing to keep the best texture.
Freeze: You can freeze the filling for up to 2-3 months. Place it in a freezer-safe container. When you're ready to use it, transfer it to the fridge and let it thaw overnight.
Reheat: Warm the fajita filling in a skillet over medium heat until heated through. Add a splash of water or vegetable broth if needed to keep it from drying out. You can also use the microwave, but the skillet works best.
Tip: Reheat the filling separately and warm the tortillas just before serving for the best texture.
