How to Make One Pot Cajun Chicken Alfredo
Step 1: Brown the Chicken
Start by heating olive oil in a large, deep skillet or pot over medium-high heat. Add the chicken pieces, sprinkle generously with Cajun seasoning, and sauté for 5 to 6 minutes. You want each piece nicely browned on the outside and cooked through—don’t rush this step, as it builds the foundation of smoky, savory flavor for your One Pot Cajun Chicken Alfredo.
Step 2: Add Garlic for Aroma
Stir in the minced garlic and let it sizzle for a full minute. This quick sauté releases all those irresistible garlicky aromas, infusing the chicken with even more flavor and prepping your kitchen for dinner magic.
Step 3: Pour in Broth and Cream
Next, pour in the chicken broth and heavy cream. Give everything a good stir, scraping any browned bits off the bottom of the pan for extra depth. This mixture will be the creamy, flavorful base that cooks the pasta and ties the whole dish together.
Step 4: Add Fettuccine and Simmer
Nestle the uncooked fettuccine right into the pot, spreading it out so it’s mostly submerged. Crank up the heat and bring everything to a gentle boil. Once bubbling, lower the heat to a simmer and cook uncovered for 12–15 minutes, stirring occasionally. The pasta will soak up the Cajun-spiked sauce, becoming tender and flavorful.
Step 5: Stir in Parmesan and Butter
When the pasta is al dente and the sauce thickens, stir in the grated Parmesan cheese and butter. This step is pure magic: the sauce becomes velvety, glossy, and impossibly creamy. Taste and season with salt and black pepper as needed.
Step 6: Finishing Touches
Turn off the heat and give everything one last loving stir. Sprinkle the chopped parsley over top for a hit of color and freshness. Your One Pot Cajun Chicken Alfredo is now ready to wow!
How to Serve One Pot Cajun Chicken Alfredo

Garnishes
Don’t underestimate the power of a beautiful garnish! A shower of fresh chopped parsley over each bowl not only adds color, but also a welcome burst of herby flavor. For extra flair, try a pinch of freshly cracked black pepper or a little more grated Parmesan right before serving.
Side Dishes
One Pot Cajun Chicken Alfredo is rich and satisfying on its own, but it pairs wonderfully with a crisp green salad or roasted vegetables. A hunk of crusty garlic bread on the side lets you savor every last drop of the creamy Cajun sauce.
Creative Ways to Present
If you’re serving guests, twirl the pasta into nests using tongs for a restaurant-style look, and fan a few extra slices of chicken on top. For weeknight fun, serve this dish family-style straight from the pot—it’s a crowd-pleaser every way.
Make Ahead and Storage
Storing Leftovers
Once cooled, spoon leftovers into an airtight container and refrigerate within two hours. The flavors deepen overnight, making One Pot Cajun Chicken Alfredo even more irresistible for lunch or dinner the next day. Eat within 3 to 4 days for the best texture.
Freezing
While the cream sauce can separate slightly when frozen and reheated, you can freeze individual portions in freezer-safe containers for up to 2 months. For best results, thaw gently overnight in the fridge and whisk the sauce while reheating.
Reheating
Warm leftovers gently in a saucepan over low heat. If the sauce appears too thick, add a splash of milk or chicken broth to loosen it up. Stir constantly to help the creamy Alfredo sauce return to its silky best.
