Ingredients
Here’s what you’ll need to whip up this deliciousness. Most of these are probably already in your pantry!
- For the Chicken:
- 1.5 lbs boneless, skinless chicken breasts: Cut into bite-sized cubes for quick cooking and easy eating.
- 2 tablespoons olive oil: Helps get a nice sear on the chicken.
- 4 tablespoons butter, divided: Because everything is better with butter, right?
- 4 cloves garlic, minced: Don’t skimp on the garlic!
- 1 tablespoon Cajun seasoning: The key to that spicy kick. Adjust to your heat preference!
- 1 teaspoon smoked paprika: Adds a lovely depth and smoky note.
- ½ teaspoon salt: Enhances all the flavors.
- ¼ teaspoon black pepper: Just a touch for seasoning.
- For the Cheesy Cajun Rotini:
- 1 lb rotini pasta: Those spirals are perfect for holding onto that creamy sauce, but any short pasta works!
- 6 tablespoons butter: The base for our luscious cheese sauce.
- 4 cloves garlic, minced: More garlic for the sauce because, why not?
- 3 tablespoons all-purpose flour: Our thickening agent for the roux.
- 3 cups whole milk: Gives us that necessary creaminess. Whole milk works best here!
- 2 cups shredded sharp cheddar cheese: For that classic cheesy flavor.
- 1 cup shredded mozzarella cheese: Adds gooey stretchiness!
- 1 tablespoon Cajun seasoning: Ties the sauce flavor into the chicken.
- ½ teaspoon salt: Seasoning the sauce.
- ¼ teaspoon black pepper: A little extra warmth in the sauce.
- 2 green onions, thinly sliced, for garnish: Adds a fresh, mild oniony bite at the end.
How to Make It
Okay, let’s get cooking! Follow these simple steps, and you’ll have a fantastic meal in no time.
First up, get that big pot of salted water boiling. You’ll need a good amount for the pasta. Add the rotini and cook it according to the package directions until it’s al dente. That means cooked through but still has a little bite to it. Nobody likes mushy pasta! Once it’s done, drain it well and set it aside. It’s waiting for its cheesy bath!
While the water’s doing its thing, let’s tackle the chicken. Grab a bowl and toss your cubed chicken breasts in it. Drizzle with the olive oil, sprinkle over the Cajun seasoning, smoked paprika, salt, and pepper. Give it a good toss with your hands or a spoon to make sure every single piece is coated in that gorgeous spice blend.
Now, let’s cook that chicken. Heat up a large skillet over medium-high heat. Melt 2 tablespoons of the butter from your chicken ingredients in the hot pan. Once it’s sizzling slightly, add the seasoned chicken cubes in a single layer if you can. You want to get some lovely color on them and sear them for about 6-8 minutes, stirring occasionally, until they’re golden brown and cooked all the way through. Don’t overcrowd the pan; cook in batches if you need to. Once they’re beautifully browned and cooked through, transfer the chicken to a plate and set it aside for a moment. Don’t clean the pan yet!
In that same skillet (the one you just cooked the chicken in!), melt the remaining 2 tablespoons of butter from your chicken ingredients over medium heat. Add the 4 cloves of minced garlic (from the chicken ingredients list) and cook for about 1 minute, stirring constantly, until it’s fragrant. Oh, the smell! Keep this garlic butter mixture and the skillet handy.
Time for the star: the cheesy sauce! Grab a separate medium saucepan and melt the 6 tablespoons of butter (from the sauce ingredients) over medium heat. Add the 4 cloves of minced garlic (from the sauce ingredients) and sauté for about a minute until fragrant.
Sprinkle the flour over the butter and garlic in the saucepan. Whisk constantly for 1-2 minutes to cook out the raw flour taste and form a smooth, golden roux. It should smell a little nutty.
Gradually pour in the whole milk, a little at a time, while whisking constantly to keep the mixture smooth. This is key for a lump-free sauce! Once all the milk is in, increase the heat slightly and bring it to a gentle simmer, whisking occasionally. Let it simmer for about 5-6 minutes until it thickens slightly. It should coat the back of a spoon.
Turn the heat down to low now. Stir in the shredded cheddar and mozzarella cheeses. Keep stirring gently until the cheeses are fully melted and the sauce is beautifully smooth and creamy. Season the sauce with the tablespoon of Cajun spice (from the sauce ingredients), salt, and pepper. Give it a little taste – does it need more spice? More salt? Adjust it to your liking!
Okay, time to bring it all together! Add the drained rotini pasta to the cheese sauce in the saucepan. Gently stir everything together with a spoon or spatula, making sure every nook and cranny of those spirals is coated in that glorious cheesy sauce. It should look incredibly inviting!
Almost there! Let’s finish the chicken. Add the cooked chicken cubes back into the skillet with the garlic butter you made earlier (the one from step 4). Give it a quick toss to coat the chicken in that extra layer of garlicky, buttery flavor. This makes the chicken extra delicious!
Serve it up! Spoon generous portions of the creamy, cheesy Cajun rotini pasta into bowls. Top generously with that amazing garlic butter Cajun chicken. Sprinkle with the thinly sliced green onions for a little pop of color and freshness. Serve warm and watch it disappear!

Substitutions & Additions
This recipe is super forgiving and easy to customize! Here are a few ideas to make it your own:
- Protein Swap: Not feeling chicken? Try shrimp (cook quickly after the garlic butter step in the chicken pan), sliced smoked sausage like Andouille (cook first to render fat), or even plant-based chicken substitutes.
- Veggie Boost: Sauté some chopped bell peppers and onions in the chicken pan before adding the chicken for a classic Cajun base. Stir in a handful of fresh spinach into the cheese sauce at the end; it will wilt beautifully.
- Pasta Shapes: Penne, farfalle (bow ties), cavatappi, or even elbow macaroni would work wonderfully in place of rotini.
- Cheese Please: Feel free to play with the cheese blend! Monterey Jack, Colby Jack, or even Pepper Jack would be delicious for an extra kick. Just make sure they’re good melting cheeses.
- Spice Level: Adjust the amount of Cajun seasoning in both the chicken and the sauce. You can add a pinch of cayenne pepper to the sauce for more heat if you like it fiery!
- Extra Richness: Stir in a few tablespoons of cream cheese or a splash of heavy cream into the cheese sauce right before adding the pasta for an even richer, creamier result.
Tips for Success
Want to make sure your pasta dish is absolutely perfect every time? Keep these tips in mind:
- Don’t Overcook the Pasta: Cook it just until al dente. Remember, it will finish cooking slightly when you stir it into the hot sauce.
- Cook the Roux Properly: Whisking the flour and butter for a couple of minutes helps eliminate that raw flour taste and ensures a smooth sauce.
- Add Milk Gradually: This is crucial for a smooth, lump-free cheese sauce. Pour slowly and whisk constantly!
- Don’t Boil the Cheese Sauce: Once the cheese is added, keep the heat low. High heat can cause the cheese to separate and become grainy.
- Taste and Adjust: Always taste the cheese sauce and the finished dish before serving. Does it need more salt? More Cajun spice? Don’t be afraid to tweak!
- Prep Ahead: You can cook the chicken and make the cheese sauce separately a day in advance. Store them in airtight containers in the fridge. Gently reheat the sauce on the stovetop with a splash of milk before combining with freshly cooked pasta and the reheated chicken.
How to Store It
If you’re lucky enough to have leftovers (it’s rare in my house!), here’s how to keep them fresh.
Store any leftover Garlic Butter Cajun Chicken Pasta in an airtight container in the refrigerator for up to 3-4 days. When you’re ready to reheat, the sauce will likely have thickened quite a bit. The best way to reheat is gently on the stovetop in a saucepan over low heat, stirring frequently and adding a splash or two of milk or chicken broth to loosen the sauce back up to your desired consistency. You can also microwave individual portions, stirring halfway through.
FAQs
Got questions? I’ve got answers!
Q: Is this dish very spicy?
A: The spice level largely depends on the Cajun seasoning you use and how much you add. The recipe calls for 1 tablespoon in the chicken and 1 tablespoon in the sauce, which gives it a noticeable but usually not overpowering kick for most people. You can easily reduce the amount of Cajun seasoning or add a pinch of sugar to the sauce to mellow the heat if needed.
Q: Can I use pre-shredded cheese?
A: While you can use pre-shredded cheese, I highly recommend shredding your own from a block if possible. Pre-shredded cheeses often contain anti-caking agents that can make your cheese sauce less smooth and sometimes a little grainy. Shredding your own results in a much creamier sauce!
Q: What kind of Cajun seasoning should I use?
A: There are many great brands out there! Find one you like. They vary in saltiness and heat, so if you’re using a new-to-you blend, start with a little less than the recipe calls for and add more to taste.
Q: Can I make this dish without the chicken?
A: Absolutely! You can omit the chicken entirely for a delicious cheesy Cajun pasta dish. Follow the sauce instructions and add some extra veggies if you like!
