Fajita Chicken and Enchilada Pasta

Bright, smoky, and comfortably cheesy, this Fajita Chicken and Enchilada Pasta is the kind of dinner that sparks joy on weeknights and earns raves on weekends. It brings together the sizzling flavors of fajitas — peppers, onions, and a bold spice blend — with the cozy, saucy comfort of enchilada-style pasta. The result is a single-pan celebration of zesty chicken, tender pasta, and melty cheese that feeds a crowd and makes excellent leftovers.

This recipe uses simple pantry spices, fresh produce, and shredded cheddar for a familiar, craveable finish. The chicken is cut into bite-sized pieces and tossed in a smoky, slightly sweet spice mix before being seared; bell peppers and onions are softened until just tender. A generous pour of enchilada sauce turns everything into a saucy, richly flavored base for penne (or any short cut pasta you prefer). A final squeeze of lime and a scattering of avocado and cilantro add fresh brightness that keeps each bite lively.

Before we get into the how-to, here’s what you’ll need. The ingredient list below is the source of truth for everything in this recipe, so have it handy.

Ingredients

• 1 pound penne pasta or other short cut pasta
• 1 pound boneless skinless chicken breast, cut into bite size pieces
• 2 tablespoons olive oil, divided
• 2 teaspoons chipotle chili powder
• 2 teaspoons cumin
• 2 teaspoons smoked paprika or paprika
• 2 teaspoons brown sugar
• 1 teaspoon chili powder
• 1/2 teaspoon crushed red pepper flakes, optional
• 1 teaspoon kosher salt
• 1 teaspoon black pepper
• 2 large red bell peppers, sliced
• 1/2 onion, sliced
• 2 cloves garlic, minced or grated
• 2 1/2 cups canned enchilada sauce
• 1/2 lime, juiced
• 1 1/4 cups finely shredded cheddar cheese
• 1 avocado, diced (optional)
• Fresh cilantro for garnish

Notes on ingredients and swaps

If you prefer a milder dish, reduce the chipotle chili powder or omit the crushed red pepper flakes. You can swap penne for any short cut pasta such as rigatoni, short fusilli, or rotini. Use smoked paprika for a deeper, woodsy note; regular paprika will still be delicious. The avocado and cilantro are optional, but they add a lovely fresh contrast to the smoky, cheesy pasta.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan (12-inch recommended)
• Wooden spoon or spatula
• Knife and cutting board
• Measuring spoons and cups

Step-by-step Instructions

The following directions have been rewritten into clearer, step-by-step wording based on the ingredient list. They keep the same order of operations and the exact ingredient amounts listed above.

1. Cook the pasta: Bring a large pot of salted water to a boil. Add 1 pound penne pasta (or other short cut pasta) and cook according to package directions until al dente. Reserve about 1/2 cup of the pasta cooking water before draining. Drain the pasta and set it aside while you make the sauce and chicken.
2. Make the spice mix: In a small bowl, combine 2 teaspoons chipotle chili powder, 2 teaspoons cumin, 2 teaspoons smoked paprika or paprika, 2 teaspoons brown sugar, 1 teaspoon chili powder, 1/2 teaspoon crushed red pepper flakes (if using), 1 teaspoon kosher salt, and 1 teaspoon black pepper. Stir until evenly mixed.
3. Season the chicken: Pat 1 pound boneless skinless chicken breast pieces dry with a paper towel. Toss the bite-size pieces with about half of the spice mix, ensuring each piece is evenly coated. You can reserve the remaining spice blend for the vegetables.
4. Sear the chicken: Heat 1 tablespoon olive oil in a large skillet or sauté pan over medium-high heat. Once the oil shimmers, add the seasoned chicken in a single layer and let it cook without moving for 1 to 2 minutes to develop a light sear. Stir and continue cooking until the chicken pieces are cooked through and no longer pink in the center, about 4 to 6 minutes total depending on size. Transfer the cooked chicken to a plate and set aside.
5. Sauté the peppers and onion: Add the remaining 1 tablespoon olive oil to the same skillet over medium heat. Add 2 large red bell peppers, sliced, and 1/2 onion, sliced. Sprinkle the reserved spice mix over the vegetables (use the remaining seasoning you set aside). Cook, stirring occasionally, until the peppers and onion soften and begin to char at the edges, about 5 to 7 minutes.
6. Add garlic: Reduce the heat to medium-low and stir in 2 cloves garlic, minced or grated. Cook for about 30 seconds to 1 minute, until fragrant, being careful not to let the garlic brown.
7. Build the sauce: Pour 2 1/2 cups canned enchilada sauce into the skillet with the vegetables and stir to combine. Bring the sauce to a gentle simmer, scraping up any browned bits from the bottom of the pan. Let it simmer for 2 to 3 minutes to meld the flavors.
8. Return chicken to the pan: Add the cooked chicken back into the skillet with the sauce and vegetables. Stir to coat the chicken evenly. Simmer everything together for 2 to 3 minutes to heat the chicken through and marry the flavors.
9. Toss with pasta: Add the drained penne pasta to the skillet and toss well to combine. If the sauce feels too thick, add a splash of the reserved pasta cooking water (start with 2 tablespoons) to loosen it until you reach the desired saucy consistency. Taste and adjust seasoning with more salt or pepper if needed.
10. Add cheese and lime: Remove the skillet from heat and stir in 1 1/4 cups finely shredded cheddar cheese until the cheese melts into the sauce, creating a creamy, cheesy coating on the pasta and chicken. Squeeze the juice of 1/2 lime over the pasta and toss once more.
11. Garnish and serve: Transfer the pasta to a serving bowl or plate. Top with diced avocado (optional) and a generous sprinkle of fresh cilantro leaves. Serve immediately so the cheese is melty and the peppers retain a bit of texture.

Serving suggestions

This Fajita Chicken and Enchilada Pasta is terrific on its own, but it also pairs well with a simple green salad, tortilla chips, or warm corn tortillas on the side. Add a dollop of plain yogurt or sour cream if you like extra creaminess, and serve lime wedges for anyone who wants more citrus brightness.

Make-ahead and leftovers

You can prepare the whole dish up to the point of adding cheese and lime, then cool it and refrigerate for up to 2 days. When reheating, warm gently in a skillet over low heat with a splash of water or broth to loosen the sauce, then stir in the shredded cheddar just before serving. Leftover pasta keeps well and the flavors often deepen overnight.

Troubleshooting

• If the sauce becomes too thick when reheating, add reserved pasta water, vegetable or chicken broth, or a splash of milk to loosen it.
• To prevent dry chicken, avoid overcooking the bite-size pieces — they cook quickly and will stay juicy if removed from the pan as soon as they’re opaque inside.
• If you want more heat, add extra chipotle chili powder or a drizzle of hot sauce at serving time.

Why this works

The technique of searing seasoned chicken first locks in flavor and creates tasty fond — those browned bits on the pan — which become flavor boosters when deglazed into the sauce. Sautéing peppers and onions until slightly charred adds sweet, smoky notes that complement the enchilada sauce. The combination of spices balances smokiness, warmth, and a hint of sweetness from the brown sugar, while lime and cilantro lift the whole dish so it never feels heavy.

Final thoughts

This Fajita Chicken and Enchilada Pasta is an approachable, flavorful dinner that reliably pleases a crowd. It’s flexible, too: swap in different bell pepper colors, use a different short cut pasta, or double the veggies for extra bulk and color. Whether you’re feeding family or meal-prepping for the week, this one-pan-style pasta offers comfort and excitement in every forkful.
