Ingredients and substitutions
- Olive oil – or another neutral cooking oil like avocado or canola oil.

- Taco seasoning – use 1 tbsp. chili powder and 1 tsp. cumin instead or make your own taco seasoning.

- Yellow onion – white onion, shallots or red onion would also be good in this recipe.

Frequently Asked Questions
Chicken fajita pasta combines two of your favourite dishes: chicken fajitas and pasta! It’s a super easy dinner idea and is ready in a flash thanks to the Instant Pot. Feel free to add on more of your favourite fajita toppings like green onions, jalapenos, corn, tomatoes and red onions.
You don't have to use store-bought taco seasoning – one of my fave meal prep tricks is to make your own at home! This way you don't get any extra sodium, and you can control what you put in it. I typically make a big giant batch of taco seasoning then store it in an airtight container along with my other spices. Just mix together chili powder, cumin, paprika, coriander, garlic powder, onion powder and chili flakes.
This recipe has 521 calories per serving. If you want to cut down on the calorie count, use low-fat sour cream or Greek yogurt and cut the amount of cheese in half (or leave it out altogether). Making your own taco seasoning is another great way of keeping this recipe healthy since you won’t be using as much sodium.
Storing and reheating
You can store this recipe in the fridge for up to 5 days and reheat it in the microwave for 2-3 minutes. Be sure to sprinkle some water over top so the pasta doesn't dry out – this is the key to reviving pasta perfectly every time so that it tastes just like new! I prefer to use glass meal prep containers because you can reheat directly in the container itself and ensure you are getting the proper portion size.
Freezing this recipe
You can freeze this pasta too! It will last in the freezer for up to 3 months. To reheat from frozen, simply sprinkle some water over top and microwave for 7-9 minutes, stirring halfway through. You can also let the pasta defrost in the fridge for up to 24 hours and then reheat as directed above.
