I’ve made a lot of pasta dishes in my time, but this Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo is one that stops the table mid-bite. The combination of bold, smoky Cajun-seasoned chicken and the luxuriously creamy mozzarella Alfredo sauce clinging to rigatoni pasta makes every forkful ridiculously satisfying. It’s that balance of heat and richness that hits all the right notes—comforting, flavorful, and just indulgent enough without being over the top.

What I love most about this dish is how it takes simple ingredients and transforms them into something that tastes like a weekend restaurant splurge. Whether I’m making it for guests or just treating myself after a long day, it’s always a hit. The crispy seared chicken against the creamy pasta is a pairing I just can’t get enough of.

What Kind of Pasta Works Best for Spicy Cajun Chicken in Creamy Mozzarella Alfredo?

I used rigatoni for this recipe because those big tubes do a fantastic job catching all that creamy mozzarella Alfredo sauce inside and out. But you’ve got flexibility here. Penne, ziti, or even fettuccine can work if that’s what you’ve got on hand. Just aim for a pasta shape that holds sauce well and has some bite to it. Rigatoni, with its ridges and sturdy size, holds up beautifully next to that spicy chicken and velvety cheese sauce.

Options for Substitutions

Sometimes you’ve got to work with what’s in the kitchen, and that’s no problem at all with this recipe. Here are a few easy swaps:

Chicken: Boneless chicken thighs instead of breasts give even more flavor and stay juicy.
Mozzarella: Feel free to use provolone, Monterey Jack, or a blend of Italian cheeses if mozzarella isn’t available.
Cream: Half-and-half or whole milk will lighten the sauce a bit if you don’t want to use heavy cream.
Pasta: Swap in gluten-free pasta, whole wheat, or any short cut pasta that holds sauce well.
Cajun seasoning: If you’re out, try a mix of paprika, garlic powder, onion powder, cayenne, oregano, thyme, and a touch of salt.
Vegetarian: Skip the chicken and toss in roasted mushrooms or grilled zucchini for a meatless version.

Ingredients for This Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo

Boneless, Skinless Chicken Breasts
These are the protein star of the dish, absorbing all the Cajun spice and getting a beautiful sear for texture and flavor.
Cajun Seasoning
This bold, smoky blend gives the chicken its spicy kick and deep color. It also ties the whole dish together with a signature Southern-style warmth.
Rigatoni Pasta
The ridged tubes trap every bit of the creamy Alfredo sauce, making each bite rich and satisfying.
Heavy Cream
The foundation of the Alfredo sauce—provides that silky, indulgent texture that makes the dish feel so luxurious.
Mozzarella Cheese
Melted into the sauce, mozzarella adds that iconic stretchy, creamy, cheesy goodness we all crave.
Butter
Used to start the sauce and cook the garlic. Adds richness and helps bring everything together.
Garlic (Freshly Minced)
Adds a layer of aromatic depth to the sauce—don’t skip it!
Olive Oil
Used for searing the chicken, helping it get that golden crust while locking in moisture.
Salt & Black Pepper
Simple but essential, these balance the spice and elevate the overall flavor.
Parsley (Fresh or Dried)
Used as a garnish and for a pop of freshness to cut through the richness of the sauce.

Step 1: Season and Prep the Chicken

Pat the chicken breasts dry and generously coat both sides with Cajun seasoning, salt, and a touch of black pepper. Let them sit for 10–15 minutes to absorb the flavors.

Step 2: Sear the Chicken

Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for 5–6 minutes on each side until golden brown and fully cooked through. Remove from the pan and let rest before slicing.

Step 3: Boil the Rigatoni

In a large pot of salted boiling water, cook the rigatoni according to package instructions until al dente. Drain and set aside, reserving about ½ cup of pasta water.

Step 4: Make the Creamy Mozzarella Alfredo Sauce

In the same skillet used for the chicken, lower the heat and add butter. Once melted, toss in the minced garlic and sauté for about a minute until fragrant.

Step 5: Add Cream and Mozzarella

Pour in the heavy cream and bring to a gentle simmer. Gradually stir in the shredded mozzarella, letting it melt into a smooth, creamy sauce. If the sauce gets too thick, use a splash of reserved pasta water to loosen it up.

Step 6: Combine Pasta and Sauce

Add the drained rigatoni into the sauce and toss well to coat every piece evenly. Let it simmer on low for 1–2 minutes to help the sauce cling to the pasta.

Step 7: Slice and Serve

Slice the rested chicken breasts into strips. Plate the creamy mozzarella rigatoni and top or serve alongside the spicy Cajun chicken. Garnish with a sprinkle of parsley for a final touch.

How Long to Cook Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo

The total cooking time is about 35–40 minutes from start to finish:

Chicken: 10–12 minutes (depending on thickness)
Pasta: 8–10 minutes for al dente rigatoni
Sauce: 10–12 minutes for building flavor and melting the cheese
Combining and simmering: Another 2–3 minutes

That means you can have this restaurant-style dinner on the table in under an hour—even faster with a little prep ahead!

Tips for Perfect Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo

Pound the Chicken Evenly: This ensures it cooks uniformly and gets that delicious golden sear without drying out.
Don’t Overcook the Pasta: Stop at al dente so it doesn’t turn mushy when mixed into the sauce.
Use Freshly Shredded Mozzarella: Pre-shredded cheese doesn’t melt as smoothly and can make the sauce grainy.
Control the Heat: Cajun spice levels vary—taste your seasoning and adjust if needed to match your heat tolerance.
Reserve Pasta Water: This starchy water is your secret weapon to thinning the sauce while keeping it creamy.
Rest the Chicken Before Slicing: Give it 5 minutes after cooking so the juices don’t run out all over your cutting board.
Finish with Fresh Parsley or Basil: Adds color and freshness that cuts through the richness beautifully.

Watch Out for These Mistakes While Cooking

Even a straightforward dish like this one can go sideways if you’re not careful. Here are the key pitfalls to avoid:

Overcooking the Chicken: Cajun seasoning can darken quickly, so don’t mistake color for doneness. Use a thermometer if needed—165°F (74°C) is the goal.
Not Letting the Chicken Rest: Cutting it too soon releases all the juices. Let it sit at least 5 minutes before slicing.
Using Pre-Shredded Cheese: It often contains anti-caking agents that prevent smooth melting. Always grate it fresh for the silkiest Alfredo.
Boiling the Cream: High heat can break the sauce. Simmer it gently and stir frequently.
Skipping Pasta Water: That reserved liquid is gold—it helps bind the sauce to the pasta and fixes any thickness issues.
Underseasoning the Sauce: Once the cream and cheese go in, give the sauce a final taste and adjust with salt and a touch more Cajun spice if needed.

What to Serve With Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo?

This dish is rich and filling, so lighter or fresh sides balance it out beautifully. Here are a few pairing ideas:

Garlic Roasted Broccoli

Roasting brings out broccoli’s nutty sweetness, and garlic ties it back into the pasta’s flavor profile.

Caesar Salad with Croutons

A crisp Caesar with tangy dressing is a classic contrast to creamy pasta.

Warm Garlic Bread

Perfect for scooping up that extra Alfredo sauce—because you won’t want any of it left behind.

Baked Parmesan Zucchini

Zucchini slices roasted with a Parmesan crust bring crunch and a lighter veggie option to the table.

Cherry Tomato Salad

Fresh cherry tomatoes, basil, and balsamic glaze help cut through the richness with a burst of acidity.

A Glass of White Wine

A cold Sauvignon Blanc or Chardonnay pairs beautifully with the creamy-spicy flavor combo.

Marinated Olives or Antipasto Plate

If serving this as part of a bigger dinner spread, a little antipasto is a fun and flavorful starter.

Storage Instructions

Leftovers? You’re in luck—Spicy Cajun Chicken Rigatoni in Creamy Mozzarella Alfredo reheats beautifully if you store it right.

Refrigerator: Store in an airtight container for up to 3–4 days. The sauce may thicken, but a splash of milk or cream while reheating brings it back to life.
Freezer: While you can freeze it, creamy sauces may separate. If you do, freeze for up to 2 months and reheat gently on the stovetop with added cream to re-emulsify the sauce.
Reheating Tips: Use a covered skillet over low heat, stirring occasionally. Add a little water, broth, or cream to loosen the sauce as it warms. Microwave works in a pinch—just heat in short intervals and stir in between.

Frequently Asked Questions

What if I don’t have Cajun seasoning?

No problem! You can make your own with paprika, cayenne, garlic powder, onion powder, oregano, thyme, and salt. Adjust the spice level to your taste.

Can I make this dish ahead of time?

Yes—prepare the sauce and chicken ahead, and store them separately. Reheat and combine with fresh-cooked pasta when you’re ready to serve.

Will it still work without heavy cream?

You can substitute with half-and-half or whole milk, but the sauce will be lighter and less rich. Add a bit more cheese to thicken it up.

Pound the chicken to even thickness and don’t overcook it. Letting it rest after cooking helps seal in those juices.

Can I add vegetables to this pasta?

Is this dish very spicy?

It has a moderate kick from the Cajun spice. You can tone it down by using less seasoning or choose a mild Cajun blend.

What kind of mozzarella should I use?

Low-moisture, whole milk mozzarella is best for melting smoothly into the sauce. Avoid pre-shredded if you can.
