Ingredients

Chicken breast is the protein of choice here. It cooks quickly and absorbs the Cajun seasoning well, adding that essential meaty bite.

Linguine is perfect for this creamy sauce. It holds onto the rich garlic parmesan base beautifully and cooks directly in the pot, saving time and dishes.

Cajun seasoning is what gives this dish its signature heat and depth. It blends paprika, cayenne, garlic powder, and other spices into a flavorful mix that makes the chicken shine.

Garlic builds the base of the sauce, providing a rich, aromatic background that enhances the cream and cheese.

Parmesan cheese melts into the sauce, adding a nutty sharpness that balances the spice.

Heavy cream is the magic that makes this sauce luscious and decadent.

Chicken broth gives the linguine enough liquid to cook while infusing the dish with added savory depth.

Butter and olive oil combine to help sear the chicken and sauté the garlic without burning, giving everything a golden, tasty foundation.

How to Make Creamy One Pot Cajun Chicken Linguine with Garlic Parmesan Sauce

Step 1: Season and Sear the Chicken

Start by cutting the chicken breast into bite-sized pieces and generously coating them with Cajun seasoning. Heat olive oil and butter in a large pot or deep skillet over medium-high heat, then sear the chicken until golden brown on all sides. Remove and set aside.

Step 2: Sauté the Garlic

In the same pot, reduce the heat slightly and add a bit more butter if needed. Sauté the minced garlic until fragrant. Be careful not to let it brown, as you want a mellow, aromatic flavor.

Step 3: Build the Sauce

Pour in the chicken broth and heavy cream, stirring to scrape up any bits from the bottom of the pan. Add the parmesan cheese and whisk until it melts into the sauce.

Step 4: Add the Pasta

Break the linguine in half if needed to fit in the pot. Add it directly to the sauce and bring everything to a simmer. Cook uncovered, stirring frequently to prevent sticking, until the pasta is tender and the sauce thickens.

Step 5: Return the Chicken and Finish

Add the seared chicken back into the pot and stir to coat it in the creamy sauce. Let everything simmer together for a few more minutes until the flavors meld. Taste and adjust seasoning if needed. Serve hot and garnish with extra parmesan or chopped parsley.

Recipe Variations and Possible Substitutions

One of the best things about Creamy One Pot Cajun Chicken Linguine with Garlic Parmesan Sauce is how easy it is to tweak based on what you have in your kitchen. Don’t have chicken breast? Try boneless skinless thighs for a richer bite, or even cooked sausage slices to bring out a smokier flavor.

If linguine isn’t your favorite or you simply ran out, fettuccine or penne will work just as well. You can also lighten the dish up a bit by using half-and-half instead of heavy cream, though the sauce won’t be quite as luscious. For a low-dairy version, use unsweetened oat milk and nutritional yeast in place of cream and parmesan—surprisingly creamy and flavorful.

Spice level can be dialed down by cutting the Cajun seasoning in half or swapped out with a milder mix like smoked paprika and thyme. Toss in spinach or kale in the last few minutes for a boost of color and nutrition, or stir in cherry tomatoes for some juicy brightness.

Serving and Pairing Suggestions

This creamy Cajun pasta is a full meal on its own, but it pairs beautifully with lighter sides that balance the richness. A crisp green salad with a tangy vinaigrette cuts through the creamy sauce, while roasted vegetables like asparagus or zucchini add depth and earthiness. Want something bready to soak up every bit of sauce? A warm slice of garlic bread or herbed focaccia will do the trick.

For drinks, go with a chilled glass of sauvignon blanc or a citrusy sparkling water with lemon. The brightness balances the creaminess and complements the spice. If you’re entertaining, a light dessert like fruit salad or lemon sorbet can round off the meal perfectly.

Storage and Reheating Tips

If you’re lucky enough to have leftovers, this pasta stores wonderfully. Transfer to an airtight container and refrigerate for up to 3 days. To reheat, add a splash of milk or cream to loosen the sauce, then warm gently on the stove or in the microwave. Avoid high heat, as it can cause the sauce to break.

You can freeze the pasta, but it’s best enjoyed fresh or refrigerated. If freezing, let it cool completely, then pack into individual portions. Reheat from frozen slowly on the stove with extra cream to revive the texture.
