Chicken Fajita Pasta brings two dinner favorites together in one skillet. You get tender pieces of seasoned chicken, colorful peppers, onions, and creamy pasta with that familiar fajita flavor in every bite.

The first time I made this, I was really just trying to use up some chicken and peppers in the fridge. Once everything started cooking together, it quickly became one of those meals I knew I would make again.
I keep the seasoning simple with chili powder, cumin, paprika, garlic, and a little lime. The combination gives the pasta plenty of flavor without needing a complicated sauce or a long list of spices.
What I like most is how flexible it is. You can make it a little spicy, add extra vegetables, or finish it with cheese and fresh cilantro. It is an easy weeknight dinner that still feels like something different from the usual pasta.
Why You Will Love This Recipe
Chicken Fajita Pasta has the comfort of a creamy pasta dinner but with the bold, smoky flavors you expect from fajitas. The peppers and onions add sweetness and texture, while the seasoned chicken makes the dish filling.
Everything comes together in one skillet after the pasta is cooked, which keeps cleanup pretty manageable. I also like that you can adjust the heat easily by adding more chili powder or a little hot sauce.
The sauce is creamy without being too heavy. A little cream cheese and pasta water are enough to bring everything together, while the lime at the end adds a fresh finish.

How to Make Chicken Fajita Pasta
- Cook the pasta: Bring a pot of salted water to a boil and cook the pasta according to the package directions until al dente.
- Save the pasta water: Before draining, reserve about ½ cup of the cooking water.
- Season the chicken: Add the chicken pieces to a bowl and season with chili powder, paprika, cumin, garlic powder, salt, and black pepper.
- Cook the chicken: Heat the olive oil in a large skillet over medium-high heat. Add the chicken and cook for about 5 to 6 minutes, stirring occasionally, until browned and cooked through.
- Cook the peppers and onions: Remove the chicken from the skillet and add the sliced peppers and onions. Cook for 4 to 5 minutes until they soften but still have a little bite.
- Bring back the chicken: Return the cooked chicken to the skillet and stir everything together.
- Make the sauce: Reduce the heat to medium and add the cream cheese and chicken broth. Stir until the cream cheese melts into a smooth sauce.
- Add the pasta: Add the drained pasta and toss everything together.
- Loosen the sauce: Add a little reserved pasta water at a time until the sauce reaches a creamy consistency that coats the pasta.
- Add the cheese: Stir in the shredded cheddar and let it melt into the sauce.
- Finish with lime: Squeeze the fresh lime juice over the pasta and stir gently.
- Taste and adjust: Add more salt, pepper, chili powder, or lime juice if needed.
- Serve: Top with fresh cilantro and extra shredded cheese if desired.
What to Serve Chicken Fajita Pasta

Chicken Fajita Pasta already has chicken, vegetables, and pasta in one dish, so I usually keep the sides simple. A fresh green salad works especially well because its crisp texture balances the creamy pasta.
You can also serve it with warm tortillas or crusty bread if you want something to scoop up the extra sauce. For a more fajita-style dinner, add a small bowl of salsa, guacamole, or sour cream to the table.
Corn is another easy side. Grilled corn, roasted corn, or even a simple corn salad works nicely with the smoky seasoning in the pasta.
If you want more vegetables, roasted zucchini or a simple tomato salad would be a good addition. I would not make too many sides, though. The pasta is filling enough to be the main event.
How to Store and Reheat
Store leftover Chicken Fajita Pasta in an airtight container in the refrigerator for 3 to 4 days. Let it cool slightly before transferring it to the refrigerator.
The sauce will thicken as it sits, so add a splash of chicken broth or water before reheating. This helps bring the creamy texture back without making the pasta watery.
For the best results, reheat it in a skillet over low to medium heat. Stir occasionally and add a little extra liquid as needed. A small handful of shredded cheddar can also help make the sauce creamy again.
You can microwave individual portions in short intervals, stirring between each one. Do not overheat the pasta, since the chicken can become dry and the creamy sauce can separate.
Finish reheated portions with a squeeze of fresh lime and a little cilantro. It brightens the leftovers and makes them taste much fresher.
