Chicken fajitas are ALWAYS a popular choice in our house so it’s no surprise that this Chicken Fajita Pasta was a huge hit also!

It’s such an easy and quick one pot meal – my kids love it because it’s packed with their favourite chicken fajita spices. I love it because it is also slimming friendly! Plus you know how much I LOVE one pot recipes… Anything that cuts down on washing up will always get the thumbs up from me! 

Cooking the pasta right in the sauce is also just altogether more delicious – just take a look at my popular Cajun Chicken Pasta or One Pot Crab Pasta. 

I used Fajita Seasoning in this recipe as I happened to have some – you can also make your own just take a look at the recipe card notes.

How to Make Chicken Fajita Pasta

1. Prep your chicken and vegetables – cut the chicken into bite-sized pieces so that it cooks quickly. Slice the onions and peppers.
2. Mist a deep lidded pan (I use this Chef’s pan) or a Dutch Oven with low calorie cooking spray or add a little olive oil. Heat the pan and add the chicken, salt and seasonings and quickly stir to combine.

3. Throw in the sliced onions and minced garlic (or garlic paste from a tube if you’re in a hurry) and cook, stirring for 5 minutes until the onions have softened slightly. Add the chopped chili and sliced peppers and stir to combine.
4. Stir in the tomato paste, chopped tomatoes and chicken stock and bring to a rolling simmer.

5. Add the pasta, stirring so that it is mostly submerged in the water and other ingredients. Lower heat to a gentle simmer and cook for 15-20 minutes, stirring occasionally, until that pasta is cooked through and most of the liquid has been absorbed.

6. At this point you can stir in some sour cream if you prefer a creamier sauce. Do this off the heat so that it doesn’t split. A little bit of lime juice, to taste, adds a lovely contrast to the mildly spicy flavors.

7. Add the grated cheese and stir so it melts into the sauce (can we say yum!). Stir in the chopped cilantro (coriander) and season with salt and pepper. Serve with a little extra cheese, if you like.

Recipe Notes and Tips

• Cooking pasta in with the sauce takes a little longer than it would if cooked separately. Make sure to give the pasta the occasional stir while this dish is cooking to avoid sticking.
• You can use any short pasta shapes you like such as penne, ziti, rigatoni etc. Use wholemeal pasta to up to the fiber content.
• Recipe variations – replace the chicken with raw shrimp or prawns, adding them to the sauce about 4 minutes before the end of the cooking time. 
• This recipe is SYN FREE on Slimming World, using some of your cheese allowance. One portion is under 500 calories and 13 SmartPoints on WeightWatchers.
• Replace the Fajita Seasoning in this recipe with two teaspoons smoked paprika, one teaspoon chili powder and half a teaspoon ground cumin.
• Store leftovers in an airtight container in the fridge for up to 3–4 days. Gently warm in a skillet or microwave, adding a splash of water if needed to loosen the sauce.
