Ingredients for Your One Pot Cajun Chicken Pasta
Gathering your ingredients is half the battle, right? I love keeping staple spices like Cajun seasoning on hand because they just transform a dish like this. For the chicken, boneless, skinless breasts are easiest, but thighs work too if you’re feeling it! Just know they might take a minute or two longer to cook.
- 1 1/2 tablespoons olive oil (divided)
- 1 pound boneless, skinless chicken breasts, cut into 1-inch pieces
- 1 1/2 tablespoons Cajun seasoning (my go-to has a nice kick!)
- 1 medium red bell pepper, sliced
- 1 medium yellow bell pepper, sliced
- 1 small red onion, thinly sliced
- 2 cloves garlic, minced (hello, flavor!)
- 2 cans low-sodium chicken broth
- 1 can fire-roasted diced tomatoes (gives it that smoky depth)
- 3/4 cup heavy cream (for that luxurious, creamy finish)
- 12 ounces penne pasta (or whichever short pasta shape you love!)
- 2 teaspoons cornstarch
- 1 tablespoon water
- 3/4 cup grated Parmesan cheese (freshly grated is best, trust me!)
- 3 tablespoons chopped fresh parsley (adds a lovely pop of freshness)
- 1/2 teaspoon salt (or to taste!)
- 1/4 teaspoon black pepper
Step-by-Step Instructions for One Pot Cajun Chicken Pasta
Okay, let’s get this party started! First things first, grab a nice big skillet or a Dutch oven – something with some depth will make life easier. Heat about a tablespoon of olive oil over medium-high heat. While that’s warming up, toss your diced chicken pieces with about half of your Cajun seasoning. Make sure they’re all coated nicely. Then, carefully add the chicken to the hot skillet in a single layer. You want them to get a good sear, so don’t crowd the pan! Cook them for about 5 to 6 minutes, flipping once, until they’re nicely browned and cooked through. The most important thing here is to make sure they reach an internal temperature of 165°F for food safety. Once they’re done, scoop them out onto a plate and cover them loosely with foil to keep warm and juicy.

Now, back to that same skillet – it’s got all those yummy bits from the chicken! Add the remaining half tablespoon of olive oil. Toss in your sliced bell peppers (both red and yellow!) and that thinly sliced red onion. Let them sauté for 3 to 4 minutes, just until they start to soften a bit. Don’t cook them to mush; we want them to still have a little bite. Next, stir in your minced garlic and the rest of that glorious Cajun seasoning. Cook for just another minute until you can smell that amazing aroma – that means the garlic and spices are releasing all their flavor!
Time for the liquid magic! Pour in the two cans of low-sodium chicken broth and the can of fire-roasted diced tomatoes. Give it a good stir to loosen up any bits stuck to the bottom of the pan. Now, stir in about half a cup of the heavy cream. Bring this whole beautiful mixture up to a boil. Once it’s bubbling away, it’s time for the pasta! Stir in your 12 ounces of penne pasta. You’ll need to reduce the heat to medium and let it cook, uncovered, for about 12 to 13 minutes. Here’s a crucial tip that makes all the difference: stir it often! This prevents the pasta from sticking to the bottom and helps the sauce get wonderfully creamy. Keep stirring until the pasta is perfectly tender.
Once the pasta is cooked, we’re going to thicken that sauce. In a small bowl, whisk together the 2 teaspoons of cornstarch with 1 tablespoon of water until it’s smooth. Now, stir this mixture into the bubbling pasta and sauce. Cook for just another minute or so until the sauce thickens up slightly. It should have a lovely, luscious consistency. Finally, take the skillet off the heat. Stir in the remaining quarter cup of heavy cream, the grated Parmesan cheese, and all that fresh chopped parsley. Add your cooked chicken back into the pot, along with the salt and pepper. Give everything a gentle stir to combine. Let it rest for about 3 minutes – this lets all those glorious flavors meld together perfectly.

Serving Suggestions for Your One Pot Cajun Chicken Pasta
This pasta dish is pretty fantastic on its own, but a few little additions can really take it over the top! Here are my favorite things to serve alongside this Cajun delight:
Crusty Bread: You absolutely need something to sop up all that incredible creamy sauce. A nice crusty baguette or some garlic bread is perfect for it!
Simple Green Salad: A light, crisp salad with a zesty vinaigrette cuts through the richness of the pasta and adds a nice fresh crunch. Super simple, super effective.
Guacamole: For a bit of cool, creamy, and fresh contrast, a scoop of my Easy Guacamole is amazing. It adds those healthy fats and a pop of lime that just works.
Grilled Corn Salad: If you want to double down on the summery, slightly smoky vibes, some Grilled Corn Salad ties into the flavors beautifully.
Storing and Reheating Your One Pot Cajun Chicken Pasta
Got leftovers? Lucky you! This One Pot Cajun Chicken Pasta actually reheats really well. Once it’s cooled down, pop your leftovers into an airtight container and stash it in the fridge. It should be good for about 3 to 4 days. I usually make a big batch specifically for meal prep because it’s just so good for lunches during the week!
When you’re ready to dive back in, you’ve got a couple of options. A quick zap in the microwave for about 90 seconds to 2 minutes, stirring halfway through, works great. If you want to get that sauce a bit creamier again, you can gently reheat it in a skillet over medium-low heat, stirring frequently, until it’s warmed through. It’s like you just made it fresh!

Frequently Asked Questions about One Pot Cajun Chicken Pasta
Can I make this One Pot Cajun Chicken Pasta recipe less spicy?
Absolutely! Cajun seasoning can vary in heat, so start with just 1 tablespoon and add more to your taste. You can also omit the chili powder if your seasoning blend is already quite zesty. It will still be incredibly flavorful!
What can I use instead of heavy cream if I want a lighter version of this pasta?
For a lighter touch, you can try using half-and-half instead of heavy cream, or even a good quality evaporated milk. Just know that it might not be quite as rich or creamy, but it’ll still be delicious! Some folks even use a bit of milk thickened with a little extra cornstarch, but I find the half-and-half gives the best flavor and texture balance.
