Ingredients: 12 oz penne pasta; 1 tbsp kosher salt for pasta water.; 1 lb boneless skinless chicken breast sliced; 2 tbsp Cajun seasoning; 1 tbsp olive oil; 1 tbsp unsalted butter; ½ tsp smoked paprika optional; black pepper to taste.; 1 red bell pepper sliced; 1 green bell pepper sliced; ½ medium yellow onion sliced; 3 cloves garlic minced.; 2 tbsp unsalted butter; 1 cup heavy cream; ¾ cup chicken broth; 1 cup grated parmesan cheese; 1 tbsp tomato paste optional; ½ tsp salt to taste; ¼ tsp black pepper; ½ cup reserved pasta water as needed.; fresh parsley for garnish; lemon wedges optional.

Cajun Chicken Creamy Pasta is my kind of weeknight dinner when I want something rich and saucy but still straightforward. You get seasoned chicken, tender pasta, and peppers that keep it from feeling too heavy.

The flavor here is smoky-spicy with a creamy parmesan sauce that clings to every piece of penne. I like this version because it tastes like a restaurant-style pasta, but it still feels like real home cooking, not fussy.

This is especially good when you want a one-skillet dinner that’s filling on its own. I usually serve it with lemon wedges and a simple salad, and call it done.

It’s a quick one: about 10 minutes of prep and 20 minutes on the stove, and it makes 4 solid servings. The spice level mostly depends on your Cajun seasoning, so you can keep it gentle or let it bite a little.

Why You’ll Love This Recipe

Weeknight Friendly: It’s done fast, and it’s the kind of dinner that doesn’t need much else on the table.

Real Cajun Flavor: The seasoning, peppers, and a little bit of smoky warmth give it that classic Cajun pasta taste.

One-Skillet Sauce: The sauce comes together right in the same pan, so you keep all those browned bits and you’re not washing extra dishes.

Extra Creamy: Parmesan and cream make a smooth sauce that actually coats the pasta instead of sliding off.

Easy to Adjust: You can calm the heat down, crank it up, or swap the chicken for shrimp without changing the whole recipe.

Key Ingredients

Pasta

Penne pasta: I like penne here because it holds onto the sauce in the ridges. Rigatoni or farfalle work too if that’s what you have.
Kosher salt: Don’t be shy with the pasta water. It’s the easiest way to keep the final dish from tasting flat.

Cajun Chicken

Chicken breast: Slice it thin so it cooks quickly and stays tender. Chicken thighs work too, just give them a little extra time.
Cajun seasoning: Use your favorite brand, but keep in mind the salt and heat levels vary a lot. If yours is salty, go lighter on extra salt later.
Olive oil: Helps the chicken sear and keeps the spices from scorching too fast.
Unsalted butter: I like the combo of oil and butter for browning and flavor. If you only have salted butter, just adjust the salt later.
Smoked paprika (optional): This adds a little smoky depth that’s really good with the peppers. It’s optional, but I use it when I have it.
Black pepper: Add it to taste since Cajun seasoning already brings some heat and bite.

Vegetables

Red bell pepper: Adds sweetness and a softer texture once it cooks down.
Green bell pepper: I like the slightly sharper flavor next to the red pepper. You can use all one color if you want.
Yellow onion: Sliced onion melts into the sauce a bit and makes the whole skillet taste more savory.
Garlic: Fresh garlic is best here. Jarred works in a pinch, but it won’t taste quite as bold.

Cream Sauce

Unsalted butter: This helps the sauce taste a little richer and rounds out the spices.
Heavy cream: This is what gives you that classic creamy Cajun pasta sauce texture. It also stands up well to the heat from the seasoning.
Chicken broth: Loosens the sauce and keeps it from feeling too thick or heavy. Low-sodium is nice if your Cajun seasoning is salty.
Parmesan cheese: Freshly grated melts smoother and doesn’t clump as much. The pre-shredded kind can work, but it’s not as creamy.
Tomato paste (optional): I like a little bit for color and a subtle savory sweetness. If you leave it out, the sauce is still great.
Salt: Taste at the end and adjust. Between the Cajun seasoning and parmesan, you may not need much.
Black pepper: A little more pepper helps the sauce taste finished.
Reserved pasta water: This is how you get a silky sauce that clings. I almost always use a splash, even if the sauce looks fine at first.

Finish

Fresh parsley: Brightens everything up and makes the pasta feel a little lighter.
Lemon wedges (optional): A squeeze at the end cuts the richness and wakes up the Cajun spices.

Recipe Instructions

Cook the pasta: Bring a large pot of water to a boil, salt it well, and cook the penne until al dente. Reserve about 1/2 cup of pasta water, then drain.
Season the chicken: Pat the chicken dry, then toss it with Cajun seasoning, smoked paprika (if using), and black pepper.
Sear the chicken: Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Sear the chicken until browned and cooked through, about 3 to 4 minutes per side, then transfer to a plate.
Cook the vegetables: In the same skillet, add the peppers and onion and cook until softened, about 4 to 5 minutes. Add the garlic and cook about 30 seconds, just until fragrant.
Make the sauce: Add the remaining 2 tablespoons butter, then stir in the chicken broth and scrape up the browned bits. Stir in the heavy cream and tomato paste (if using) and simmer 2 to 3 minutes.
Add the parmesan: Reduce the heat to low and stir in the parmesan until smooth. Thin the sauce with reserved pasta water as needed.
Toss and serve: Return the chicken and any juices to the skillet, add the drained pasta, and toss until coated and heated through, about 1 to 2 minutes. Taste and adjust salt, pepper, and Cajun seasoning, then garnish with parsley and serve with lemon wedges if you want.

My Tips!

This is the section that separates “good” from “wow.” If you read only one part of this post, make it this one — it’s where I reveal my recipe trick.

Recipe Tips & Tricks

Slice the chicken thin. Thin slices cook fast and stay juicy. If the pieces are thick, the outside can brown before the middle is done.

Keep the heat under control. Cajun seasoning can burn if the pan is screaming hot, especially once the spices hit the skillet. Medium-high is plenty for a good sear.

Use low heat for the cheese. Parmesan melts smoother when the sauce is not boiling. If it’s bubbling hard, pull the pan off the heat for a minute, then stir.

Don’t skip the pasta water. Even a small splash helps the sauce cling to the penne instead of sitting at the bottom of the pan. Add it a little at a time so it doesn’t get too thin.

Adjust the spice at the end. I’d rather add a pinch more Cajun seasoning at the finish than overdo it up front. If it’s too spicy, a little extra cream in the skillet helps.

Simple tweaks

Here’s where the fun begins — a few simple tweaks can turn this recipe from casual treats into the star of any party.

Serving Suggestions

Salad: A simple chopped romaine salad with cucumbers and tomatoes is great next to this. I usually do a light vinaigrette.
Bread: Garlic bread or a warm crusty loaf is really useful for swiping up the extra sauce. Even basic dinner rolls work.
Vegetables: Roasted broccoli, green beans, or asparagus are easy on the side. Keep the seasoning simple since the pasta has a lot going on.
Garnish: Extra parmesan, fresh parsley, and a squeeze of lemon make each bowl taste brighter. If you like more heat, add a pinch of Cajun seasoning on top.
Drink: I like this with iced tea or sparkling water with lemon. Anything light is nice with a creamy pasta.

Eat it later

This section explains how to store leftovers properly and how far in advance the recipe can be prepared.

Storage and Make Ahead

Store leftovers covered in the fridge for up to 4 days. The sauce thickens as it sits, which is normal for a cream sauce.

Reheat portions gently on the stove or in the microwave. I usually add a small splash of water, broth, or cream while reheating so the pasta loosens back up.

You can prep parts ahead by slicing the peppers, onion, and chicken earlier in the day. It makes the actual cooking go really fast.

If you want it longer term, you can freeze individual portions, but cream sauces can separate a bit when thawed. It still tastes good—just reheat slowly and stir well, and add a splash of cream or broth if needed.

Recipe FAQs

How spicy is Cajun Chicken Creamy Pasta?

It depends almost entirely on your Cajun seasoning. Some blends are mild and more herby, and some are pretty hot.

If you’re unsure, start lighter on the seasoning and add more at the end. A squeeze of lemon and a little extra cream can calm it down if it gets too spicy.

Can I use half-and-half instead of heavy cream?

Yes. The sauce will be a bit thinner and it usually needs a little longer simmer to thicken.

I’d keep the heat fairly low once the dairy is in so it doesn’t get grainy, and use pasta water to help it come together.

Why did my parmesan clump in the sauce?

This usually happens when the sauce is too hot or the cheese is pre-shredded and doesn’t melt as smoothly. Take the pan down to low heat (or off the heat for a minute) and stir steadily.

Freshly grated parmesan helps a lot, and adding it gradually instead of all at once helps too.

Can I swap the chicken for shrimp?

Yes, shrimp works great here. Season it the same way, then cook it quickly—about 1 to 2 minutes per side—so it doesn’t get rubbery.

I usually cook the shrimp after the veggies, then pull it out and add it back at the end like the chicken.

What other add-ins work well?

Spinach and mushrooms are both easy here. Add mushrooms with the peppers and onion, and stir spinach in at the very end so it just wilts.
