The first night I tossed together this Garlic Parmesan Chicken Spaghetti in a Cajun-tinged creamy sauce, it was cold enough outside to crave a big, cozy bowl. The kitchen smelled amazing as garlic and butter started sizzling, mixing with all those Cajun spices and bubbling cheese. Right then, I could tell it would hit the spot—rich and bold, but not totally overpowering, with just the right kick to wake up your taste buds.
I first tried pressing Parmesan onto chicken to jazz up a boring weeknight pasta. Searing it after made the chicken way more fun—crunchy outside, cheesy all around, but still juicy inside. It goes so well with the creamy sauce, too.
Irresistible Ingredients
- Heavy cream: keeps the sauce ultra-creamy with loads of richness; go for full-fat for the smoothest finish.
- Mozzarella and sharp cheddar: these two bring a sharp, stretchy goodness to pull the sauce together.
- Parmesan cheese: you'll want fresh-grated so the flavor really pops, both in the chicken crust and the sauce.
- Smoked paprika: adds a deep, toasty smokiness that makes Cajun dishes sing.
- Cream cheese: melts into the sauce to thicken and bring out a slight tang.
- Spaghetti: opt for classic durum wheat pasta—holds up in creamy sauce without falling apart.
- Cajun seasoning: a must for zingy Southern heat; go homemade or store-bought, just be sure it’s got both spice and herbs balanced.
- Chicken breasts: lean, soak up flavor best when they’re firm and fresh.
- Fresh garlic: you want plump, hard cloves to get that punchy aroma right.
Look for the best dairy you can find and fresh herbs if you’re adding them. Cream cheese should feel soft, not chunky. Parmesan from a block, grated right before, gives you way more flavor than bagged stuff. Fresh garlic will feel solid and snap a bit when you squeeze it.
How To Make It
- Tossing Pasta In Sauce
- Get your spaghetti right into the pan with the sauce—al dente is best—so every noodle soaks up all that flavor.
- Simmering To Meld Flavors
- Let the sauce bubble gently to mix herbs, cheese, and spices. This mellows the heat and makes the sauce super cozy and thick.
- Building The Cream Sauce
- Swirl together cream and broth, melt in both cream cheese and grated cheeses a little at a time for a sauce that's thick but never gloopy.
- Infusing Garlic Butter
- Just before you take out the chicken, drop garlic into butter so the whole kitchen smells savory and full of flavor.
- Searing The Parmesan-Crusted Chicken
- Cover seasoned chicken with Parmesan, press it on tight, then fry it up for an epic, cheesy crust that stays juicy inside.

Top Highlights
- Comforting, still packs lean protein thanks to chicken and cheese
- Fits special diets: use gluten-free pasta or even zoodles and the cheesy sauce still shines
- Herbs and spices make it bold but not overwhelming
Once I rushed and threw in the cream cheese while the sauce was blazing hot—ended up a little lumpy. Now I always take my time, keep heat gentle, and whisk. That’s how you keep the sauce velvety. Sometimes, your mess-ups make you better in the kitchen.
Taste Twists
Want more smoky? Try chipotle powder instead of smoked paprika. Love herbs? Throw in fresh basil or oregano at the end. If you’re the spicy type, sprinkle extra red pepper flakes or dash in some hot sauce before serving.
Gear You’ll Need
A non-stick skillet really helps when browning cheesy chicken—less cleanup, too. Grab a wooden spoon or silicone spatula for stirring the melty stuff, and a whisk with a tighter mesh keeps your sauce super smooth when you’re mixing in the cream cheese.
Secret Moves
- Press that Parmesan in good—don’t just sprinkle—so you get a real, crispy edge on the chicken.
- Let cream cheese warm up on the counter so it blends easily (cold stuff gets clumpy).
- Keep the sauce on low, stirring lots, so everything melts together without burning or splitting.

Common Questions
- → How can I keep the chicken crust crispy?
Dry the chicken well before seasoning and pressing on the Parmesan. Then cook it over medium-high heat without crowding the pan so the crust stays crisp.
- → What’s the easiest way to stop spaghetti from overcooking?
Boil the spaghetti just until it’s al dente. Drain it, then toss it in olive oil so it won’t stick while you prepare the sauce.
- → Can the sauce be made less spicy?
Definitely. You can add or skip red pepper flakes depending on how much heat you want. Adjust the Cajun seasoning to your liking too.
- → How do I make sure the sauce gets thick enough?
Once the cheeses and cream cheese are in, let the sauce simmer gently. This helps it thicken without boiling hard.
- → What’s a good substitute for chicken broth?
If you don’t have chicken broth, vegetable broth or water works fine, but the sauce might be a bit less rich.
- → Can I prepare this in advance?
It tastes best fresh, but you can cook parts ahead and heat everything together later to keep the texture nice.
