  • Preheat the oven to 392°F / 200°C
    Mix all the spices and dried herbs together in a small mixing bowl.

    Pour the marinade over the vegetable, add the salt and pepper and mix well. Leave the vegetables to soak up the marinade for about 10 minutes.

  • Nutritional information is calculated using an online nutrition tool and is approximate. The information does not include tortillas, sour cream, cheese or/and avocado. 
  • This recipe makes enough to serve 4 people, we used 2 medium tortillas per person. This recipe is easy to scale up, please see the scale tool in the recipe card.
  • If you want to make these quicker then skip marinating the vegetables. I have made these both ways and they are absolutely fine without the 10-minutes to marinate.
  • Make them Vegan, these vegetable fajitas are vegan I haven't listed them as such as I have added cheese and sour cream to the final dish.
  • Make them Gluten Free, use your favourite gluten-free tortillas.
  • Storing these vegetable fajitas, these are really best made and eaten fresh however if you have any leftover vegetables then you can keep them in the fridge for a day or two. I don't recommend freezing the vegetables as they will get soggy once defrosted.
  • Reheating, add any leftover cooked vegetables to a skillet and cook with a little oil until they are piping hot.
