Fajita Seasoning – Short on time? Use two tablespoons of your favorite premade fajita spice blend instead of mixing your own. Just be sure to choose one without added cornstarch—it can thicken the sauce too much.

Bell Peppers – Use any combination of bell peppers you like. The mix of red, green, and yellow adds color and flavor, but you can stick to one or two types based on what you have on hand.

Chicken – This recipe would be just as delicious with chicken thighs if you prefer dark meat to white meat.

Pasta – Bow-tie, rigatoni, rotini, or any other short pasta will work just as well as penne in this one-pot dish.

Cheese – Colby-jack melts beautifully into the sauce and keeps things mild and creamy. For a kick, swap in pepper-jack. Prefer a classic flavor? Mild cheddar works too.

Broth – If using low or no sodium chicken broth, you may want to add an additional ½ teaspoon of salt to the seasoning blend.

🌶️ This dish has a bold, smoky flavor but stays mild on the heat—perfect for families and spice-sensitive eaters. If you want to turn it up a notch, add ⅛ to ¼ teaspoon of cayenne pepper or swap in pepper-jack for an extra kick. 🌶️

🔥 Pro Tips for the Best Chicken Fajita Pasta

Sear the chicken in batches if needed
If your skillet is crowded, cook the chicken in two batches so it browns instead of steaming. Golden edges = better flavor.

Don’t overcook the veggies
Stop cooking the peppers and onions once they’re just tender but still vibrant. You want that classic fajita texture—not soggy veg.

Stir the pasta once halfway—no more, no less
Stirring halfway helps prevent sticking without over-agitating the starches, which can make the sauce gluey.

Add cream and cheese gradually
After cooking, reduce the heat (or remove the skillet from heat entirely), then stir in the cream and cheese slowly. This keeps the sauce silky and prevents curdling.

🍽️ How to Serve

  • Serve hot, straight from the pot — it’s best fresh!
  • Top with extra shredded cheese or a dollop of sour cream.
  • Garnish with fresh cilantro or sliced green onions.
  • Pair with a simple green salad or Spanish Rice.
  • Add lime wedges on the side.

    Storing a Mexican Pasta

    This one pot pasta is best served fresh, but leftovers can be saved for later. Store any cooled leftovers in an airtight container in the refrigerator for up to three days. The pasta will continue to absorb the sauce as it sits, so it may thicken over time.

    To reheat, warm the pasta gently in a skillet over medium heat. Add a splash of chicken broth or cream to help loosen the sauce and bring back that creamy texture. Avoid microwaving in large batches, as it can dry out the chicken—reheat in smaller portions if using the microwave.

    🚫 We don’t recommend freezing this fajita pasta—the creamy sauce can separate and the pasta tends to get mushy once thawed. 🚫

    Make Ahead: Chicken, onion, bell peppers, and garlic can all be pre-chopped and stored in airtight containers in the refrigerator until you are ready to make this recipe. Make sure to store the raw chicken in a separate container.

    Big flavour, one pot, so easy to make—that’s dinner done right. This one-pot chicken fajita pasta checks all the boxes: hearty, creamy, loaded with veggies, and guaranteed to leave clean plates. Definitely one to keep in the weeknight rotation.

    Ingredients
      

    • 2 teaspoons chili powder
    • 1 teaspoon garlic powder
    • 1 teaspoon onion powder
    • ¾ teaspoons salt
    • ½ teaspoon ground cumin
    • ½ teaspoon dried oregano
    • ¼ teaspoon black pepper
    • 3 tablespoons olive oil divided (2 tablespoons to cook the chicken and 1 tablespoon for the vegetables)
    • 1 ½ pounds boneless skinless chicken breasts cut into ½ inch strips
    • 1 cup large yellow onion approximately half, cut into ½ inch strips
    • 1 cup red bell pepper seeded and cut into ½ inch strips (approximately 1 medium pepper)
    • 1 cup green bell pepper seeded and cut into ½ inch strips (approximately 1 medium pepper)
    • 1 cup yellow bell pepper seeded and cut into ½ inch strips (approximately 1 medium pepper)
    • 2 ½ cups chicken broth
    • 8 ounces penne pasta
    • ¼ cup heavy cream
    • 1 cup grated colby-jack cheese
    • Chopped fresh cilantro optional garnish

    Instructions
     

    • Combine together in a small bowl the chili powder, garlic powder, onion powder, salt, ground cumin, dried oregano and black pepper. Set aside.
    • Add 1 tablespoon of the seasoning blend to the chicken breast strips and toss to evenly coat.
    • To a large (12 inch) heavy duty skillet over medium-high heat, add 2 tablespoons olive oil. When the oil is hot, add the seasoned chicken breast strips. Cook the chicken for 6-8 minutes or until golden brown and no pink remains.
    • Transfer the cooked chicken to a plate and set aside.
    • Add the remaining 1 tablespoon olive oil, yellow onion, red bell pepper, green bell pepper, yellow bell pepper and remaining seasoning blend to the skillet. Stir to coat the vegetables in the seasoning blend and cook for 4-6 minutes or until the vegetables are crisp tender.
    • Add the chicken broth and penne pasta to the skillet. Stir to combine.
    • Bring the liquids to a boil then reduce the heat to medium-low. Cover the skillet with a tight fitting lid and simmer the pasta for 12-15 minutes or until the pasta is tender. Be sure to stir the pasta half way through the cooking process to ensure that all the pasta is cooking evenly.
    • Remove the lid to the skillet. Stir in the heavy cream and shredded colby-jack cheese until the cheese is fully melted and the sauce is thickened.
    • Add the chicken back to the skillet and stir to combine all the ingredients. Remove the chicken fajita pasta from the heat. Sprinkle with chopped fresh cilantro if desired for garnish.

      I was curious can this be done in the slow cooker??? Adding the pasta and cream at the end?? If so how long could I cook 4 or 6 hours on high or low?
