Ingredients

Chicken breast is the star of this dish, giving the pasta a hearty, satisfying bite. You want it tender and juicy, with enough surface area to absorb all the Cajun flavor.

Olive oil is essential for searing the chicken. It adds richness and helps develop that delicious golden crust while also acting as the base for building flavor in the pan.

Cajun seasoning brings the spice and smoky depth that sets this Alfredo apart. It’s bold, slightly fiery, and absolutely delicious against the creamy sauce.

Garlic infuses the sauce with a warm, savory aroma that deepens the flavor of the entire dish. It’s one of those must-have ingredients that elevates everything.

Chicken broth provides the liquid needed to cook the pasta while infusing it with savory flavor. It’s much more flavorful than plain water.

Heavy cream makes this Alfredo sauce luscious and thick, coating each piece of pasta in velvety goodness.

Uncooked pasta, like penne or fettuccine, cooks right in the same pot, soaking up every drop of flavor and cutting down on extra dishes.

Parmesan cheese is stirred in at the end for a salty, nutty finish that ties the sauce together beautifully.

How to Make One Pot Cajun Chicken Alfredo

Step 1: Sear the Chicken

Heat olive oil in a large pot over medium-high heat. Season the chicken breasts generously with Cajun seasoning and sear them until golden on both sides and cooked through. Remove the chicken and set aside.

Step 2: Build the Flavor Base

In the same pot, add minced garlic and cook for a minute until fragrant. This step creates a rich base of flavor from the browned bits left behind by the chicken.

Step 3: Add Liquids and Pasta

Pour in the chicken broth and heavy cream. Bring the mixture to a simmer, then stir in the uncooked pasta. Let it cook uncovered, stirring occasionally, until the pasta is tender and the liquid has thickened into a creamy sauce.

Step 4: Return the Chicken

Slice the seared chicken and return it to the pot. Let it warm through in the sauce, allowing the Cajun spices to mix into the Alfredo base.

Step 5: Finish with Cheese

Stir in freshly grated Parmesan cheese until melted and smooth. Taste and adjust seasoning as needed.

Step 6: Serve

Serve hot with extra Parmesan and a sprinkle of Cajun seasoning if you want more kick.

Recipe Variations and Possible Substitutions

You can play with this One Pot Cajun Chicken Alfredo in all sorts of ways. If you’re not a fan of chicken breast, swap it out for chicken thighs or even shrimp for a Cajun seafood twist. To make it vegetarian, skip the meat and add mushrooms, spinach, or zucchini for a hearty plant-based version. Not into spicy? Use less Cajun seasoning or opt for a mild version. And if you’re dairy-free, coconut cream and nutritional yeast can be used to create a creamy, flavorful alternative.

Different pasta shapes work too—short types like penne or rigatoni hold the sauce beautifully, but fettuccine or linguine give a more elegant feel. You could even use whole wheat or gluten-free pasta to suit dietary needs.

Serving and Pairing Suggestions

This dish is rich and creamy, so I love serving it with something light and crisp to balance it out. A simple green salad with a lemon vinaigrette cuts through the richness nicely. Garlic bread or warm crusty rolls are perfect for scooping up any extra sauce.

If you want to round it out into a bigger meal, roasted vegetables like broccoli, asparagus, or Brussels sprouts make a fantastic side. A chilled glass of white wine like Chardonnay or a sparkling lemonade pairs well too.

Storage and Reheating Tips

Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, add a splash of cream or milk and warm it on the stove over medium heat until everything is creamy again. You can also microwave it in 30-second bursts, stirring in between.

If you plan to freeze it, keep in mind that the cream sauce may separate slightly when thawed. Stirring in a little extra cream or broth while reheating usually brings it back together.
