Where are fajitas from?

Fajitas originated in Western Texas in the 1930s. Mexican ranch workers working along the American/Mexican border wanted a tasty way to incorporate skirt steak into their meals, and so the fajita was born! These days, recipes have evolved to include much more than skirt steak, but the basics are still the same…some seasoned meat and vegetables all wrapped up in a tortilla and served with a dollop of guacamole. Yum!

Our oven chicken fajitas

Our fajitas are made with mildly spiced chicken, peppers and onions and served with a choice of toppings including guacamole, yogurt and cheese. They are super simple to put together as the chicken and vegetables all go into one pan in the oven to cook. While it’s cooking you can whip up a simple and wholesome guacamole topping. Put it all on the table with some freshly warmed tortillas and dinner is served!


One pan chicken fajitas

  • ½ red pepper
  • ½ green pepper
  • 1 medium red onion
  • 2 skinless free-range chicken breasts
  • 1 teaspoon smoked paprika
  • 1 small pinch of ground cumin
  • 2 limes
  • 2 tablespoons olive oil
  • fresh coriander to garnish


  • 4 cherry tomatoes
  • 1 ripe avocado
  • Juice of 2 limes

To serve

  • 4 small flour tortillas
  • 180 ml natural yoghurt
  • 75 grams Cheddar cheese grated


  1. Preheat the oven to 180°C.
  2. Halve the green and red pepper and deseed them both. Slice half of the pepper into long thin strips.
  3. Top and tail the onion and remove the outer skin, cut into thin slices. Slice the chicken into strips.
  4. Put the chicken, peppers, and red onion in a bowl with 2 tablespoons of olive oil, paprika and cumin. Squeeze the juice of half a lime over everything, season with salt and pepper and mix well.
  5. Put it in the fridge to marinate for 20 minutes or more. If you’re short on time, just move on to the next step.

Put everything into a bowl and drizzle 2 tablespoons olive oil over the top.

Add  your cumin and paprika, squeeze the juice of half of a lime over the mix and add salt and freshly milled black pepper.

Stir to mix everything up and cover all the pieces in oil.

You can let everything marinate in the fridge….leave it for anywhere from 20 minutes to overnight, or if you’re pressed for time, just give it all a good stir and move onto baking!

Place your chicken and veg and on oiled baking tray.

Give each piece it’s own individual space to cook and avoid overlapping.

Tongs are useful for spreading everything out evenly.

Now bake for 20-30 minutes, making sure the chicken is cooked through and everything is nice and tender.

While your fajitas are baking get started on your homemade guacamole, which will be a lot tastier (and healthier) than the store bought kind!

All you need to do is drop four cherry tomatoes, a chopped (ripe) avocado and the juice of two limes into your blender and whizz everything up.

Take it out of the blender and stick it in the fridge until your fajitas are out of the oven.
