Ingredients

  • 1 pound macaroni
  • 2 cups chicken stock
  • 1/2 cup heavy cream
  • 1 packet (about 2 tablespoons) fajita seasoning
  • 1 teaspoon salt
  • 3 (about 1 1/2 pounds) boneless skinless chicken breasts, diced
  • 2 tablespoons olive oil
  • 1 small onion, finely diced
  • 2 red bell peppers, finely diced
  • 2 cloves garlic, minced
  • 1 cup shredded cheddar cheese
  • chopped fresh parsley, for garnish

Equipment

  • Large deep skillet or Dutch oven with lid
  • Cutting board
  • Sharp knife
  • Box grater
  • Wooden spoon

Instructions

  1. Heat the olive oil in a large deep skillet or Dutch oven over medium heat, then add the onion, red bell peppers, and garlic. Cook, stirring often, until the vegetables soften and turn translucent, about 5 to 6 minutes, so they melt into the sauce instead of staying crunchy.
  2. Push the vegetables to the edges of the pan to make a well in the center, then add the diced chicken in a single layer. Sprinkle in the fajita seasoning and salt, and let the chicken sear undisturbed for a minute or two so it picks up a little color and the spices bloom.
  3. Pour in the heavy cream, chicken stock, and dry macaroni, then stir everything together until the pasta is submerged in the liquid.
  4. Reduce the heat to low, cover, and simmer gently for about 20 minutes, stirring once or twice, until the macaroni is tender and most of the liquid has thickened into a creamy sauce.
  5. Add the shredded cheddar and stir until it melts smoothly into the pasta, coating every noodle. If it looks too thick, splash in a little extra stock.
  6. Sprinkle with chopped parsley and serve hot.

Tips from the kitchen

  • Cut the chicken into even bite-sized pieces so it cooks through at the same rate the pasta does.
  • Shred your own cheddar off the block if you can; pre-shredded cheese has anti-caking agents that can make the sauce grainy.
  • Stir the pasta once or twice while it simmers so it doesn't stick to the bottom of the pan.

Make it your own

  • Swap the red bell peppers for a mix of red and green, or add a diced jalapeno for extra heat.
  • Use a blend of cheddar and Monterey Jack or pepper jack for a meltier, spicier finish.
  • Trade the chicken for sliced smoked sausage or leftover rotisserie chicken to save time.

Storing & make-ahead

Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stove or in the microwave with a splash of stock or cream to loosen the sauce back up.

Good to know

Can I use a different pasta shape?
Yes. Any short pasta like penne, shells, or rotini works, but check the package cook time and adjust the simmer so it turns out tender.
My sauce got too thick. What happened?
The pasta keeps soaking up liquid as it sits. Just stir in a little extra warm chicken stock or cream until it's creamy again.
Can I make my own fajita seasoning?
Absolutely. Mix chili powder, cumin, smoked paprika, garlic powder, onion powder, and a pinch of cayenne, roughly 2 tablespoons total.
Is this spicy?
It's mild to medium depending on your seasoning packet. Add jalapeno or pepper jack cheese to turn up the heat.
