Instructions

  1. Season the chicken
    In a bowl, coat the chicken with olive oil, garlic powder, onion powder, Cajun seasoning, oregano, paprika, and salt.
  2. Cook the chicken
    Heat a little oil in a hot pan over medium-high heat. Add the chicken and cook until golden and fully cooked through. Remove from the pan and set aside.
  3. Cook the pasta
    Boil the rigatoni in salted water until al dente. Reserve a little pasta water before draining.
  4. Start the sauce
    In the same pan, melt the butter over medium heat. Add the diced onion and red bell pepper and cook until softened.
  5. Add the garlic and tomato paste
    Stir in the minced garlic and tomato paste and cook for another minute or two.
  6. Season the sauce
    Add the red pepper flakes, Cajun seasoning, garlic powder, oregano, and cayenne powder. Stir well so the spices bloom.
  7. Add the cream
    Pour in the heavy cream and let it come to a gentle simmer.
  8. Finish the sauce

  10. Add the chicken back
    Slice the cooked chicken and add it back on top of the pasta or mix it in before serving.

About this recipe

This creamy Cajun chicken pasta is one of those dinners that feels a little extra but is actually so easy to make. It has everything you want in a comforting pasta dish: juicy seasoned chicken, tender rigatoni, a creamy sauce, plenty of garlic, and just enough spice to make it really flavorful. It’s the kind of meal that works for weeknights when you want something satisfying, but it also feels good enough to make when you want dinner to feel a little more special.

What makes this recipe so good is the balance of flavors. The chicken is seasoned really well with Cajun seasoning, paprika, garlic, and oregano, while the sauce gets extra depth from onion, red bell pepper, tomato paste, parmesan, and a little heat from cayenne and red pepper flakes. The spinach adds a bit of freshness, and the rigatoni holds onto the sauce perfectly, so every bite is creamy and full of flavor.

This is also a great recipe because it feels customizable. You can make it a little spicier, add more vegetables, or adjust the creaminess depending on what you like. If you’re looking for an easy creamy Cajun chicken pasta recipe that tastes restaurant quality but comes together at home, this is such a good one to make.

Good to know

Why you'll love it

  • It tastes like a restaurant-style pasta but is easy enough for a weeknight
  • The Cajun-seasoned chicken adds so much flavor and makes the dish extra satisfying
  • The sauce is creamy, rich, and perfectly balanced with a little spice

Ingredient notes

  • Chicken breasts: Slicing the chicken breasts in half helps them cook more evenly and more quickly.
  • Cajun seasoning: This is the main flavor base for the chicken and part of the sauce, so use one you really like. Some blends are saltier than others.
  • Paprika: Paprika adds color and warmth and works really well with the Cajun spices.
  • Rigatoni: Rigatoni is a great shape for this sauce because the creamy sauce gets inside the pasta and coats it well.
  • Heavy cream: Heavy cream gives the sauce its rich texture. It helps balance the spice and makes the pasta extra creamy.
  • Butter: Butter adds richness and helps build the sauce base with the onion, pepper, and garlic.
  • Yellow onion and red bell pepper: These add sweetness, flavor, and texture to the sauce.
  • Garlic: Fresh minced garlic adds a lot of flavor, so it’s worth using fresh here.
  • Tomato paste: Tomato paste adds depth and helps round out the creamy sauce.
  • Spinach: A handful of spinach adds freshness and color and wilts right into the sauce.
  • Parmesan: Freshly grated parmesan melts more smoothly and gives the sauce the best flavor.
  • Cayenne and red pepper flakes: These add heat, so you can adjust them depending on how spicy you want the pasta.

Tips & tricks

  • Pound the chicken slightly if needed so it cooks more evenly.
  • Do not overcrowd the pan when cooking the chicken or it will not brown as nicely.
  • Reserve some pasta water before draining in case you need to loosen the sauce.
  • Let the spices cook briefly in the pan before adding the cream so they bloom and taste more flavorful.
  • Add the parmesan over low heat so it melts smoothly into the sauce.
  • Do not overcook the spinach — it only needs a minute or two to wilt.
  • Slice the chicken after resting it for a few minutes so it stays juicy.

Storage & make-ahead

Storage: Store leftovers in an airtight container in the fridge for up to 3 days.

Reheating: Reheat gently on the stove or in the microwave with a splash of water, milk, or cream to loosen the sauce.

Make ahead: You can season and cook the chicken ahead of time, and you can also chop the vegetables in advance to make dinner faster.

Best tip: Cream-based pasta sauces thicken as they sit, so add a little liquid when reheating to bring the sauce back to life.
