Ingredients

Scale
  • 1 pound (450g) chicken breast, cut into bite-sized pieces
  • 2 tablespoons olive oil
  • 2 medium bell peppers (one red, one green), sliced thin
  • 1 medium yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons fajita seasoning (store-bought or homemade blend with chili powder, cumin, paprika, oregano, and a pinch of cayenne)
  • 2 cups (480ml) low sodium chicken broth
  • 8 ounces (225g) uncooked penne or rotini pasta
  • 1/2 cup (120ml) heavy cream
  • 1 1/2 cups (170g) shredded sharp cheddar cheese
  • 1/2 cup shredded Monterey Jack or mozzarella cheese (optional)
  • Salt and pepper to taste
  • A handful fresh cilantro, chopped (for garnish)
  • Juice of half a lime

Instructions

  1. Slice bell peppers and onion thinly, mince garlic, and cut chicken into bite-sized pieces (about 10 minutes prep).
  2. Heat 2 tablespoons olive oil in a large deep skillet or pot over medium-high heat until shimmering (1-2 minutes).
  3. Add chicken pieces in a single layer and cook for 4-5 minutes, stirring occasionally, until chicken starts to brown but is not fully cooked.
  4. Add sliced onions, bell peppers, and minced garlic; cook for about 4 minutes, stirring, until veggies soften but still have a little crunch and garlic is fragrant.
  5. Sprinkle in 2 tablespoons fajita seasoning, salt, and pepper; stir well to coat evenly.
  6. Pour in 2 cups chicken broth and 1/2 cup heavy cream; stir to combine.
  7. Add 8 ounces uncooked pasta, gently pushing it down to submerge in liquid.
  8. Bring mixture to a gentle boil, then reduce heat to medium-low; cover with lid slightly ajar and simmer for 12-15 minutes, stirring occasionally to prevent sticking.
  9. Check pasta at 12 minutes for tenderness; add a splash more broth or water if needed and cook a few more minutes.
  10. Turn off heat and stir in 1 1/2 cups shredded cheddar and 1/2 cup shredded Monterey Jack or mozzarella if using; mix until cheese melts into creamy sauce.
  11. Squeeze fresh lime juice over the top and sprinkle chopped cilantro; give a gentle stir.
  12. Serve hot immediately, optionally topped with sour cream or sliced avocado.

Notes

If sauce is too thick, add a splash of broth or water to loosen. Avoid overcrowding pan to ensure chicken browns well. Stir occasionally during simmering to prevent pasta sticking. Leftovers thicken; add milk or broth when reheating. Can substitute chicken with turkey or tofu and use veggie broth for vegetarian version. Gluten-free pasta alternatives work well.
