One Pot Creamy Cajun Chicken Penne
Some nights you want a real dinner without dragging out five pots and pans, and this is exactly that meal. Everything cooks together in one skillet, the pasta soaks up all that spicy, creamy sauce, and you’ve got dinner on the table in about half an hour. This is the kind of recipe that gets requested again the following week.
Why You’ll Love This Recipe

First off, it’s genuinely one pot. No boiling pasta separately, no dirtying a strainer, no extra saucepan for the sauce. Everything happens right in the skillet, which means less cleanup and more actual eating time.
The flavor is the other big win here. Cajun seasoning gives the chicken and sauce a warm, smoky kick, and it’s balanced out by a rich, creamy base that keeps things from getting too spicy for picky eaters. It’s comfort food with a little personality.
It’s also fast. This isn’t a recipe you need to plan a whole weekend around — it comes together on a busy Tuesday just as easily as it would for guests.
Ingredients You’ll Need

You’ll want boneless, skinless chicken breasts or thighs here, cut into bite-sized pieces so they cook quickly and evenly. Thighs stay a little juicier if you tend to overcook chicken, so don’t be afraid to swap them in.
Cajun seasoning is really the heart of this dish. Store-bought blends work great, but if you have a favorite homemade mix, use that instead. Just taste as you go, since some blends run saltier than others.
For the pasta, penne is ideal because those ridges and hollow centers grab onto the creamy sauce. You could use rotini or rigatoni in a pinch, though cook times may shift slightly.
The sauce comes together with chicken broth, heavy cream, and a good handful of parmesan cheese. Diced tomatoes add a little brightness and acidity that cuts through the richness, and garlic and onion build the savory base everything else sits on. Bell peppers are optional, but they add nice color and a bit of sweetness that plays really well with the cajun spice.
Tips for the Best Results

Tip: don’t skip searing the chicken first. Getting a little golden color on the outside before you add the liquid builds a lot of flavor into the sauce.
Keep an eye on your pasta while it simmers and stir occasionally so it doesn’t stick to the bottom of the pot. Every stove runs a little different, so start checking for doneness a couple minutes before the package time suggests.
If your sauce looks too thick once the pasta is cooked, splash in a little extra broth or cream to loosen it up. It’ll also thicken more as it sits, so don’t panic if it seems slightly loose right off the heat.
Freshly grated parmesan melts smoother than the pre-shredded stuff, which tends to have anti-caking additives that can make your sauce a bit grainy.
Storage and Reheating

Leftovers keep well in an airtight container in the fridge for up to 4 days. The pasta will keep absorbing sauce as it sits, so don’t be surprised if it looks thicker the next day.
Note: when reheating, add a splash of broth, milk, or cream before microwaving or warming it on the stove. This brings the sauce back to life instead of leaving you with dry, clumpy pasta.
Reheat gently, either in the microwave in short bursts, or in a skillet over low heat, stirring often. This isn’t a dish that loves the freezer, since cream sauces can separate once thawed, so it’s best enjoyed within that first few days.
Frequently Asked Questions

Can I make this less spicy?
Yes, just use a mild cajun blend or cut the amount you add, then taste and adjust as you go.
Can I use a different protein?
Shrimp works really well here and cooks even faster than chicken, or you could use andouille sausage for a smokier take.
Can I make this ahead of time?
It’s best fresh since the pasta keeps soaking up sauce, but you can prep your chicken and veggies ahead to speed up cooking later.
Is this recipe freezer-friendly?
It’s not ideal for freezing because the cream sauce can separate when thawed, so it’s better as a fridge-and-eat-within-a-few-days kind of meal.
