I can almost smell the garlic and butter when I think about this Easy Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce. The kitchen hums with the gentle clatter of pots and the soft sizzle of chicken hitting a hot skillet. That sound means dinner is on its way, and everyone will gather around the table soon.

I started making this recipe on busy weeknights when my kids needed something comforting but quick. It pairs well with backyard conversations and small victories like finishing homework or learning to ride a bike. If you love creamy pasta with a warm kick, you are in the right place.

Why this works

This dish works so well because it balances speed and flavor. The Cajun seasoning gives the chicken a lively, smoky flavor while the garlic mozzarella sauce keeps everything smooth and kid-friendly.

It is a real time-saver. You cook the pasta while you brown the chicken and then make the sauce in the same pan. That means fewer dishes and more time to set the table and help little hands.

The flavors are built in simple layers. The roux thickens the sauce and holds the cheesy goodness. The cream cheese adds a silky body so that every forkful clings to the spaghetti.

Process Overview

“This is where the magic happens—when the aroma fills the kitchen.”

I break this recipe into three simple parts: cook the pasta, brown the chicken, and make the sauce. The sauce comes together quickly, so having your ingredients ready makes a big difference.

You will whisk the sauce smooth, return the chicken, and toss everything with pasta. This method keeps the chicken juicy and the sauce creamy.

If you like one-pan dinners, this is a great technique. For another hands-off option that pairs well with pasta nights, check out my easy crockpot chicken thighs with creamy gravy: Easy Crockpot Chicken Thighs with Creamy Gravy.

Ingredients

Below are the ingredients you will need. I include small tips next to each one to make the dish even better.

1 pound boneless, skinless chicken breasts, cut into bite-sized pieces. Tip: Trim any fat and pat the chicken dry so it browns evenly.
2 tablespoons olive oil. Tip: Use a good-quality olive oil for a clean flavor.
2 tablespoons Cajun seasoning. Tip: Taste before adding more. Store-bought is fine or mix your own if you like it milder.
1 teaspoon smoked paprika. Tip: This adds warmth and a gentle smokiness without heat.
1 pound spaghetti. Tip: Use a sturdy spaghetti that holds up to the sauce, and reserve a cup of pasta water if you need to loosen the sauce.
4 tablespoons butter. Tip: Unsalted butter lets you control the final salt level.
4 cloves garlic, minced. Tip: Mash the garlic with the side of your knife for a more aromatic release.
1/4 cup all-purpose flour. Tip: Measure by spooning into the cup for accuracy.
3 cups whole milk. Tip: Whole milk gives the richest, creamiest texture for families.
1 cup chicken broth. Tip: Use low-sodium broth so you can adjust salt later.
8 ounces cream cheese, softened. Tip: Let it sit at room temperature for easier melting.
2 cups shredded mozzarella cheese, divided. Tip: Part-skim mozzarella melts well and keeps things lighter.
1/2 cup grated Parmesan cheese. Tip: Freshly grated Parmesan will give the best depth.
Salt and freshly ground black pepper, to taste. Tip: Add in small amounts and taste as you go.
Optional: Red pepper flakes for extra heat. Tip: Add a pinch at a time. My kids like it without heat but the family can add their own sprinkle at the table.

If you are feeding picky eaters who prefer simpler flavors, try leaving out the red pepper flakes and use a milder Cajun blend. For another recipe the family loves, my grilled Asian chicken skewers with honey garlic sauce are a hit: Easy Grilled Asian Chicken Skewers with Honey Garlic Sauce.

Directions

Cook spaghetti according to package directions in salted water until al dente. Drain and set aside.
- Encouraging note: It is okay if the pasta is just shy of perfect. It will finish cooking a bit in the sauce.
While pasta cooks, season chicken with Cajun seasoning and smoked paprika.
- Encouraging note: Rub the spices in with your hands. Letting the chicken sit for a few minutes helps the flavors sink in.
In a large skillet, heat olive oil over medium-high heat. Add chicken and cook until browned and cooked through, about 6–8 minutes. Remove from skillet and set aside.
- Encouraging note: A good sear locks in juices and gives great texture. If pieces stick, give them another 30 seconds to release.
In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
- Encouraging note: Watch the garlic so it does not brown. That first burst of aroma tells you the sauce is beginning.
Sprinkle in the flour and whisk continuously for 1–2 minutes to form a roux.
- Encouraging note: Whisking keeps the roux smooth. This step builds the body of your sauce.
Gradually whisk in the milk and chicken broth, stirring constantly to avoid lumps. Bring to a gentle simmer.
- Encouraging note: If the sauce looks too thick, stir in a splash of the reserved pasta water.
Add cream cheese and 1 cup of mozzarella, stirring until melted and smooth.
- Encouraging note: Soften the cream cheese first for a silkier result. Keep stirring until everything is glossy.
Stir in Parmesan cheese and season with salt, pepper, and red pepper flakes if using.
- Encouraging note: Taste and adjust seasonings. A small pinch more salt can bring the flavors together.
Add cooked chicken back into the sauce and simmer for 2–3 minutes to heat through.
- Encouraging note: This short simmer lets the flavors mingle without drying the chicken.
Add cooked spaghetti to the skillet and toss to coat in the sauce.
- Encouraging note: Use tongs for even coating. If the sauce clings too tightly, add a tablespoon of pasta water at a time.
Sprinkle remaining 1 cup mozzarella on top, cover, and let sit for 2–3 minutes until cheese melts.
- Encouraging note: The covered melt gives you that irresistible stringy cheese that everyone loves.
Serve hot, garnished with fresh parsley or extra Parmesan if desired.
- Encouraging note: A sprig of parsley brightens the plate. Bring it to the table family-style and watch the smiles.

If you need a softer spice approach for toddlers or sensitive palates, reduce the Cajun seasoning by half in the seasoning step. For helpful tips on shaping family meals, you may enjoy my chicken kofta recipe with creamy garlic yogurt sauce: Chicken Kofta with Creamy Garlic Yogurt Sauce.

Serving

This dish shines when you serve it family-style in a large, warm serving bowl. Place the skillet or bowl in the center of the table and let everyone help themselves.

Provide simple sides like a crisp green salad and crusty bread to soak up extra sauce. A small dish of red pepper flakes or extra Parmesan allows each person to season to taste.

For a more formal dinner, plate individual portions with a sprinkle of parsley and a lemon wedge. The citrus brightens the dish and adds a fresh note that kids can skip if they prefer.

Storage

Leftovers keep well and make a wonderful next-day lunch.

Fridge: Store in an airtight container for up to 3 days. Cool the pasta to near room temperature before sealing.
Reheat gently: Use a skillet over low heat with a splash of milk or chicken broth to revive creaminess. Stir frequently until heated through.
Freezing: I do not recommend freezing this dish with the mozzarella melted on top. If you freeze, leave out the mozzarella topping and freeze in a shallow container for up to 1 month. Thaw overnight in the fridge and reheat gently.
Tip: If the sauce separates upon reheating, whisk in a tablespoon of cream cheese or a splash of milk to bring it back together.

Kitchen Notes

Shortcut: Use rotisserie chicken in step 3 to save time. Simply shred and fold into the sauce.
Shortcut: Pre-shred your mozzarella to avoid clumping. Bagged shredded cheese works well for weeknights.
Shortcut: Make the sauce ahead and store it separately. Reheat and add freshly cooked pasta for the best texture.
Shortcut: Use a nonstick skillet for easier cleanup when cooking the chicken.
Shortcut: Double the sauce recipe and freeze half in a freezer-safe bag for busy nights.

Variations

For picky eaters: Reduce the Cajun seasoning and smoked paprika. Finish with extra Parmesan for a familiar cheesy flavor.
Gluten-free: Use a gluten-free all-purpose flour for the roux and gluten-free spaghetti. The method stays the same.
Lighter version: Substitute whole milk with a mixture of part-skim milk and half-and-half. Use low-moisture part-skim mozzarella.
Shrimp swap: Replace chicken with peeled shrimp and reduce cooking time accordingly. Shrimp cooks very quickly and pairs well with the garlic-mozzarella sauce.
Veggie-forward: Add sliced bell peppers and spinach when you return the chicken to the sauce. Wilted greens add color and nutrients.

FAQ

Q: Can I use chicken thighs instead of breasts?
A: Yes. Chicken thighs stay moist and add extra flavor. Cut them into bite-sized pieces and adjust the cooking time until they reach 165°F.

Q: Why does my sauce sometimes get lumpy?
A: Lumps usually come from adding cold milk too quickly or not whisking the roux well. Warm the milk a little and add it slowly while whisking.

Q: Can I make this dairy-free?
A: For dairy-free, try a dairy-free cream cheese and a plant-based milk with a thicker mouthfeel, like canned coconut milk thinned with broth. Use dairy-free shredded cheese if available. Expect a slightly different texture.

Q: Is this recipe spicy?
A: The Cajun seasoning gives a warm flavor. If you or the kids prefer milder food, reduce the Cajun seasoning or skip the red pepper flakes.

Q: How do I keep the chicken from getting dry?
A: Cut the chicken into similar-sized pieces and do not overcook. Remove it from the pan once it is cooked through and return it to the sauce just to heat through.
