Ingredients

• ▢8 oz pasta, any shape
• ▢1 lb boneless skinless chicken breasts, cut into small bite size pieces (about 1/2 inch)
• ▢3 tablespoons fajita seasoning, homemade or store bought packet, see note below for recipe
• ▢2 tablespoons olive oil
• ▢1 bell pepper, any color, seeded and sliced
• ▢1 medium onion, sliced
• ▢5-6 cloves fresh garlic, minced
• ▢1 cup heavy cream
• ▢1/2 cup cheddar cheese

Simple homemade fajita seasoning (optional)

If you’d like to make your own fajita seasoning instead of using a packet, whisk together the following: 2 teaspoons chili powder, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon dried oregano, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. This makes roughly 1 tablespoon, so double or triple to reach the 3 tablespoons called for in the recipe.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan with a lid
• Tongs or a slotted spoon
• Measuring spoons and cups

Prep tips

• Cut the chicken into uniform 1/2‑inch pieces so it cooks evenly and quickly.
• Slice the bell pepper and onion into thin strips so they soften while the chicken finishes.
• Grate the cheddar ahead of time for a smoother melt into the sauce.
• Bring your pasta water to a boil while you start cooking the chicken so everything finishes around the same time.

Step-by-step instructions

1. Cook the pasta: Bring a large pot of salted water to a boil. Add 8 oz pasta and cook according to package directions until al dente. Reserve about 1/2 cup of the pasta cooking water, then drain the pasta and set it aside. Keeping a bit of the starchy water helps loosen the sauce later if it becomes too thick.
2. Season the chicken: Place the 1 lb cut chicken pieces in a bowl and sprinkle 3 tablespoons fajita seasoning over them. Toss thoroughly so each piece is evenly coated with seasoning. This ensures the chicken is flavorful from the first sear.
3. Brown the chicken: Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Once hot, add the seasoned chicken in a single layer. Let it sear undisturbed for 1–2 minutes so it develops color, then stir and continue cooking until the chicken is cooked through and no longer pink in the center, about 4–6 minutes total depending on piece size. Transfer the cooked chicken to a plate and set aside. You don’t need to perfectly finish cooking the chicken now as it will reheat with the sauce, but make sure it’s mostly cooked through.
4. Sauté the vegetables: In the same skillet, add the sliced bell pepper and sliced onion. If the pan looks dry, add a small drizzle of olive oil. Cook, stirring occasionally, until the vegetables are softened and beginning to caramelize, about 4–6 minutes. The peppers should be tender but still have a bit of bite for texture.
5. Add the garlic: Reduce the heat to medium, then add the 5–6 cloves minced garlic to the skillet with the softened vegetables. Sauté the garlic for 30–60 seconds until fragrant, taking care not to let it burn.
6. Build the creamy sauce: Pour in 1 cup heavy cream and stir to combine with the vegetables and any browned bits in the skillet. Bring the mixture to a gentle simmer. Allow it to cook for 2–3 minutes so the cream warms through and starts to thicken slightly.
7. Melt in the cheese and finish the sauce: Reduce the heat to low and add 1/2 cup cheddar cheese to the skillet. Stir until the cheese melts into the cream, creating a smooth, velvety sauce. If the sauce seems very thick, stir in reserved pasta water a tablespoon at a time until you reach the desired consistency.
8. Combine chicken and pasta: Return the cooked chicken to the skillet and stir to reheat and coat the pieces in the sauce. Add the drained pasta and toss gently until the pasta is fully coated with the creamy fajita sauce and the chicken and vegetables are evenly distributed. Taste and adjust seasoning if needed — a pinch of salt or a grind of black pepper can make the flavors pop.
9. Serve: Spoon the Creamy Chicken Fajita Pasta into bowls or onto plates. For brightness and contrast, garnish with a squeeze of lime, chopped fresh cilantro, or a sprinkle of additional cheddar if desired. Serve hot.

Notes and variations

• Pasta shape: Any shape works — try penne, rotini, farfalle, shells, or even spaghetti. Smaller shapes hold the sauce well; long noodles also make for fun twirls on the fork.
• Vegetable add-ins: Add sliced mushrooms, zucchini, or a handful of baby spinach for extra veggies. Add mushrooms when you cook the peppers and onions so they have time to release their liquid and caramelize.
• Cheese swap: If you like a sharper finish, use Monterey Jack or pepper jack for a little heat. For a milder, creamier result keep the cheddar.
• Spice level: If you want more kick, stir in a pinch of red pepper flakes or dice a jalapeño along with the peppers and onions.
• Make it lighter: Substitute half-and-half for heavy cream if you prefer a slightly lighter sauce, keeping in mind the texture will be somewhat thinner.
• Leftovers: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of water or cream to loosen the sauce if needed.

Serving suggestions

• Serve with a simple green salad or a crunchy slaw to add freshness and contrast to the rich pasta.
• Warm flour tortillas on the side make an easy way to turn leftovers into fajita-style wraps.
• A squeeze of lime and a scattering of chopped fresh cilantro or green onions brighten each bite and add color.

Troubleshooting

• If the sauce is grainy after adding cheese, remove the pan from high heat and stir slowly until it smooths. Cheddar can sometimes separate if added over very high heat.
• If the chicken is overcooked, reduce the searing time next time and finish cooking through in the sauce to keep it tender.
• Too-thick sauce? Add a splash of the reserved pasta water or more cream a tablespoon at a time until it loosens.
