Creamy Cajun Chicken Pasta combines seasoned chicken, colorful bell peppers, fire-roasted tomatoes, linguine, and a rich, creamy sauce in one pot. It's an easy, flavor-packed dinner that's ready in about 30 minutes.
Place the chicken breast cubes in a large mixing bowl. Add the Old Bay seasoning and toss until the chicken is evenly coated.
2½ pounds boneless skinless chicken breasts, 4 tablespoons Old Bay seasoning
Heat the cooking oil in a large stockpot or Dutch oven over medium heat until shimmering but not smoking.
2 tablespoons cooking oil
Add the chicken, scraping any remaining seasoning from the bowl into the pot. Sear briefly on all sides for 2-3 minutes.
Add the onion, bell pepper, and garlic. Sauté for 1-2 minutes, until fragrant.
¾ cup yellow onion, 1½ cups bell pepper, 1 tablespoon garlic
Pour in the chicken broth and undrained fire-roasted tomatoes. Bring the mixture to a boil.
4 cups chicken broth, 1 can fire-roasted diced tomatoes
Once boiling, add the linguine. Simmer for 9-11 minutes, or until the pasta reaches your desired texture. Stir frequently to prevent the pasta from sticking together.
12 ounces linguine
Remove 1 tablespoon of the hot cooking liquid from the pot and mix it with the cornstarch to make a thick slurry.
2 tablespoons cornstarch
Stir the cornstarch slurry into the pasta and simmer for 1 minute.
Turn off the heat and gradually stir in the heavy cream.
¾ cup heavy cream
Remove the pot from the heat and allow the pasta to rest for 5 minutes to cool slightly and thicken.
Garnish with chopped green onions or fresh chopped parsley, if desired. Serve warm.

Notes
🥡 Storage
Allow leftover Cajun Chicken Pasta to cool before storing.
Transfer leftovers to an airtight container and refrigerate for 3-4 days.
The pasta will continue to absorb some of the sauce while refrigerated, so expect it to thicken as it sits.
♨️ Reheating
Reheat individual portions in the microwave until heated through.
Larger portions can be gently reheated on the stovetop.
Because the pasta thickens during storage, you may need to loosen the sauce slightly while reheating.
Make sure the chicken reaches an internal temperature of 165°F before serving.
❄️ Freezing
Cool the Cajun Chicken Pasta completely before freezing.
Transfer it to an airtight freezer-safe container.
Freeze for 2-3 months.
Thaw overnight in the refrigerator before reheating.
Keep in mind that creamy sauces and cooked pasta can have a slightly different texture after freezing and thawing.
💡 Tips for best results
Cut the chicken into similar-sized pieces so it cooks evenly.
Don't fully cook the chicken during the initial sear. It will continue cooking as the pasta simmers.
Stir the linguine frequently while it cooks to prevent the noodles from sticking together.
Different Cajun seasoning blends vary in salt and heat. Adjust the amount according to the seasoning you're using and your preferred spice level.
Mix the cornstarch thoroughly with the hot cooking liquid before adding it back to the pot.
Turn off the heat before gradually adding the heavy cream.
Let the finished pasta rest for the full 5 minutes. The sauce will continue to thicken as it sits.
🍳 Alternate cooking methods
No alternate cooking methods are recommended for this recipe. The one-pot stovetop method allows the pasta to cook directly in the seasoned broth and helps create the creamy sauce.
♻️ Leftovers
Turn leftovers into a quick lunch by reheating individual portions.
Serve smaller portions alongside a green salad or roasted vegetables.
If the pasta has absorbed too much sauce during storage, loosen it slightly when reheating.
📝 Notes
The spice level can easily be adjusted by changing the amount or type of seasoning.
For more heat, add cayenne pepper or crushed red pepper flakes.
For a milder version, reduce the seasoning or use plain diced tomatoes.
Spaghetti or fettuccine can replace the linguine, but cooking times may vary.
Penne can also be substituted, although you may need to adjust the cooking time or amount of liquid.
Half-and-half or whole milk can replace the heavy cream, but use less since they are thinner.
The pasta may look fairly saucy when you first turn off the heat. Allow it to rest for 5 minutes before deciding whether it needs additional thickening.
