Equipment

  • Large ovenproof pan or Large skillet and oven dish

Ingredients
  

  • 320 g chicken cubed
  • 3 peppers red, yellow, and green, thinly sliced
  • 1 onion
  • 3 tablespoon fajita seasoning
  • 1 tablespoon tomato puree
  • 1 teaspoon chipotle paste
  • 150 ml double cream
  • 250 ml chicken stock
  • 150 g mozzarella grated
  • 50 g cheddar grated
  • 300 g pasta

Instructions
 

  • Preheat your oven to 200°C (392°F). In a large ovenproof skillet over medium heat, add a splash of oil and toss in your sliced peppers and onion, season with salt and pepper. Sauté for about 6 to 7 minutes until they become soft and slightly caramelized. Add the pasta on to boil and cook for 3 minutes less than the package instructions.

  • Add in the cubed chicken to the pan with the onions and peppers and sprinkle over the fajita seasoning. Stir everything together and cook for around 5 minutes until the chicken is just cooked through.

  • Stir in the tomato puree and chipotle paste, letting them coat the chicken and vegetables for a minute. Pour in the double cream and chicken stock. Season with a pinch of salt and pepper. Let the sauce simmer gently for 2 to 3 minutes, allowing everything to meld.

  • Drain the pasta, saving a little pasta water, and stir it into the sauce. Add a splash of the pasta water to help loosen the sauce and coat the pasta evenly. Stir in half the grated cheddar cheese, then transfer everything into an oven-safe baking dish.
  • If baking in the skillet, top the dish with the remaining cheddar and all of the mozzarella. If baking in a tray then transfer the mixture and top with the cheeses. Bake for 20 minutes until the top is golden and bubbling.

Notes

Take time to soften the peppers and onions properly before adding the chicken. This unlocks their natural sweetness and builds a strong flavor base. If you rush this stage, the vegetables can stay a little raw and won’t melt into the sauce as beautifully as they should.
