What You’ll Need (Full Ingredient List)
Before we get cooking, let’s round up everything. The good news: all of these are easy to find at any grocery store, and you probably have several already in your pantry.

- 3 cups whole milk
- 1 cup chicken broth
- 8 ounces cream cheese, softened
- 2 cups shredded mozzarella cheese, divided

That’s it! Nothing fancy, nothing you need to hunt down. Just real, flavorful ingredients that come together into something truly special.
A Quick Word on the Star Players
Understanding what each ingredient does helps you cook with confidence – and make smart swaps if needed.
Cajun Seasoning + Smoked Paprika – This is the soul of the dish. Cajun seasoning is a bold blend of paprika, cayenne, garlic powder, oregano, and thyme. The smoked paprika adds an extra layer of depth and that gorgeous reddish color on the chicken.
Cream Cheese – Don’t skip this. It’s the secret to that ultra-silky, velvety sauce texture. Make sure it’s softened before you add it so it melts in smoothly without clumping.
Whole Milk + Chicken Broth – This combination gives you creaminess AND savory depth. Using only milk makes the sauce too sweet; using only broth makes it too thin. Together? Perfection.
Two Kinds of Cheese – Mozzarella melts beautifully and gives you those gorgeous stretchy pulls. Parmesan adds a sharp, nutty edge that keeps the sauce from being one-dimensional.
Al Dente Spaghetti – Pull it a minute before the package says it’s done. It finishes cooking in the sauce and soaks up all that Cajun garlic goodness without going mushy.
How to Make Cajun Chicken Spaghetti – Step by Step
Ready to cook? Here’s exactly how to pull this off, from start to finish.
Step 1: Season and Rest the Chicken
Cut your chicken breasts into bite-sized pieces – roughly 1-inch chunks work great.
Toss them in a bowl with the 2 tablespoons olive oil, 2 tablespoons Cajun seasoning, and 1 teaspoon smoked paprika. Mix until every piece is thoroughly coated.
Let it sit for 10 minutes while you prep everything else. This little rest makes a big difference – the spices start to penetrate the meat and you get more flavor in every bite.
Step 2: Cook the Spaghetti
Bring a large pot of water to a boil. Salt it generously – it should taste like the ocean. Add your spaghetti and cook until just al dente (about 1 minute less than the package says).
Drain and set aside. Don’t rinse it! The starch on the pasta helps the sauce cling.
Step 3: Sear the Chicken to Golden Perfection
Heat a large skillet over medium-high heat. Add the seasoned chicken in a single layer.
Cook for 6 to 8 minutes, turning occasionally, until the pieces are golden-brown on the outside and cooked through. You want those slightly crispy edges – they add incredible texture against the creamy sauce.
Pro Tip: Don’t overcrowd the pan! If your skillet isn’t huge, cook the chicken in two batches. Crowding = steaming, and you want that beautiful sear.
Once done, remove the chicken and set it aside on a plate. Don’t clean the skillet – all those browned bits left behind are pure flavor gold.
Step 4: Build Your Garlic Butter Roux
In the same skillet, reduce heat to medium. Add the 4 tablespoons of butter and let it melt.
Add the 4 cloves of minced garlic and sauté for about 1 minute, stirring constantly. You want it fragrant and golden – not brown.
Now sprinkle in the 1/4 cup of flour and whisk it in immediately. Keep whisking for about 1 to 2 minutes. This cooks out the raw flour taste and creates the thick base for your sauce.
Your kitchen is going to smell absolutely incredible right now.
Step 5: Whisk in the Liquids
Slowly pour in the 3 cups of whole milk, whisking constantly as you go. Then add the 1 cup of chicken broth, continuing to whisk.
Bring everything to a gentle simmer over medium heat and let it cook for 3 to 4 minutes, stirring frequently, until the sauce visibly thickens and coats the back of a spoon.
You’ll see it transform right in front of you – thin and pale one moment, rich and silky the next.
Step 6: Melt in the Cheeses
Reduce the heat to medium-low. Add the 8 ounces of softened cream cheese and stir until it’s completely melted and smooth. No lumps allowed!
Now add 1 cup of the shredded mozzarella (save the other cup for topping) and the 1/2 cup of Parmesan cheese. Stir until everything is melted together into one gorgeous, glossy, cheesy sauce.
Season with salt, black pepper, and red pepper flakes if you want that extra kick.
Step 7: Bring It All Together
Add the cooked chicken back into the sauce and stir to combine. Let it simmer for 2 to 3 minutes so the chicken heats through and soaks up all that saucy goodness.
Now add the drained spaghetti to the skillet. Toss everything together until every strand is coated in that luscious Cajun garlic mozzarella sauce.
Take a moment to appreciate what you’ve just created. You’ve earned it.
Step 8: The Golden Finish
Sprinkle the remaining 1 cup of shredded mozzarella evenly over the top.
Cover the skillet with a lid and let it sit on low heat for 2 to 3 minutes until the cheese melts into a gooey, stretchy layer on top. Or, for a golden bubbly crust, transfer to an oven-safe dish and broil for 2 to 3 minutes – but watch it closely! Broilers move fast.
Finish with a handful of fresh chopped parsley and a sprinkle of extra Parmesan. Then serve it hot, straight from the skillet.
How to Customize This Recipe for Your Party Crowd
This is where the fun really starts. This pasta is incredibly flexible – here’s how to make it work for any group.
Adjusting the Heat Level
Hosting a mixed crowd with different spice tolerances? No problem.
To make it milder: Use only 1 tablespoon of Cajun seasoning, skip the red pepper flakes, and add an extra ounce of cream cheese to the sauce. You’ll still get all the flavor without the fire.
To make it spicier: Add 1/4 teaspoon of cayenne pepper, double up on the smoked paprika, or stir a splash of your favorite hot sauce into the finished sauce. For serious heat lovers, both red pepper flakes AND cayenne is the move.
Pasta Swaps
Don’t have spaghetti on hand? Totally fine. This sauce works beautifully with:
- Fettuccine for a heartier, thicker bite
- Penne if you’re planning to bake it casserole-style
- Linguine for an elegant dinner party presentation
- Gluten-free pasta to make it celiac-friendly – just watch the cook time
Protein Options
Chicken thighs are actually even juicier than breasts if you prefer dark meat. Just add a minute or two to the cook time.
Rotisserie chicken is a total lifesaver when you’re short on time. Just shred it, toss with the Cajun seasoning, warm it in the pan, and fold it into the sauce. Done in half the time.
Cheese Variations
No mozzarella in the fridge? Monterey Jack melts just as beautifully. Want something smokier? Smoked gouda adds an incredible depth that takes this dish to a whole new level.
Make It Vegetarian
Skip the chicken and swap in roasted mushrooms, chickpeas, or even crispy tofu. Use vegetable broth instead of chicken broth. The creamy garlic mozzarella sauce is the star either way.
Make-Ahead Tips for Stress-Free Party Hosting
Here’s one of my favorite things about this recipe: you can do almost all the work ahead of time.
Prepare the entire dish up through the step where you toss the pasta and chicken into the sauce. Stop before adding the final cup of mozzarella on top. Cover tightly and refrigerate for up to 2 days.
When party time comes, top with the remaining cheese and either broil until golden or cover and heat through on the stovetop with a small splash of milk to loosen the sauce. It tastes just as incredible – sometimes even better, because the spices have had extra time to meld.
For bigger parties, make a double batch in a large casserole dish. Prep it the morning of, refrigerate, and broil right before guests arrive. That golden, bubbly cheese top is guaranteed to get a reaction.
How to Store and Reheat Leftovers
Good news: this pasta reheats like a dream.
In the fridge: Store in an airtight container for up to 4 days. When reheating, add a splash of milk or chicken broth to the pan and warm it over low heat, stirring gently. The sauce comes right back to its creamy, glossy self.
In the freezer: Let the pasta cool completely, then portion into freezer-safe containers. It keeps well for up to 2 months. Thaw overnight in the fridge and reheat on the stovetop with a bit of added milk.
Microwave hack: If you have to microwave it, do it in 60-second bursts and stir between each one. This keeps the sauce from separating.
Leftover remix idea: Spread the leftovers in a baking dish, add a fresh layer of mozzarella on top, and bake at 375°F for 15 minutes. Instant Cajun pasta bake. You’re welcome.
How to Serve It Like You Mean It
This pasta is stunning on its own, but if you want to really pull off a full party spread, here are some winning combinations.
For the table: Serve it straight from a cast iron skillet or a rustic ceramic baking dish for that “I cooked all day but it was effortless” vibe.
Garnish ideas: Freshly chopped parsley, a light dusting of smoked paprika, and a drizzle of garlic olive oil right before serving. Simple, beautiful, and it photographs incredibly well.
Side dishes that pair perfectly:
- Toasted garlic bread or warm cheesy focaccia (great for mopping up that sauce)
- A crisp arugula salad with lemon vinaigrette to cut through the richness
- Roasted green beans or grilled asparagus for a fresh, light contrast
- A simple cherry tomato salad to cool down any Cajun heat
Drink pairings: A chilled Sauvignon Blanc or a buttery Chardonnay pairs beautifully with the creamy garlic sauce. For non-alcoholic options, sparkling water with lemon is perfect.
Frequently Asked Questions
Can I make this for a large party crowd?
Absolutely – and it scales up like a dream. Double the recipe and use a large casserole dish or roasting pan. You can assemble it ahead of time, refrigerate it, and broil right before guests arrive. It serves 10 to 12 people easily when doubled.
What if I don’t have Cajun seasoning?
Make your own quick blend! Combine 1 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon cayenne, 1/4 teaspoon dried oregano, and salt and pepper to taste. Works perfectly.
Can I use heavy cream instead of whole milk?
Yes! Heavy cream will make the sauce even richer and thicker. If you go this route, you can reduce the amount slightly – use about 2 cups of heavy cream instead of 3 cups of whole milk.
How is this different from Alfredo?
Great question! Traditional Alfredo is butter, cream, and Parmesan – simple and mild. This Cajun Chicken Spaghetti adds garlic, Cajun seasoning, smoked paprika, cream cheese, AND mozzarella. The result is so much more layered, bold, and complex. It’s not even really a competition.
Can kids eat this?
With a few tweaks, yes! Reduce the Cajun seasoning to 1/2 tablespoon, skip the red pepper flakes entirely, and use a mild paprika instead of smoked. The creamy garlic mozzarella sauce is kid-approved all the way.
