- Minced garlic: Fresh and fragrant, it elevates the savory flavor base.

- Half and half: Creates a luscious, creamy sauce without heaviness.

How to Make One Pot Cajun Chicken Alfredo Recipe
Step 1: Sear the Chicken
Start by heating the olive oil over medium-high heat in a large pot or deep skillet. Sprinkle the cubed chicken generously with Cajun seasoning, then add it to the hot oil. Let the chicken pieces brown and cook through, which should take about 5 to 7 minutes. Browning is key here—it locks in juices and gives you a crispy texture that contrasts beautifully with the creamy sauce. Once cooked, remove the chicken from the pot and set it aside.
Step 2: Sauté the Garlic
Using the same pot (this is the beauty of the one-pot method—minimal cleanup!), add the minced garlic and sauté it for about a minute, just until it becomes fragrant. This quick step helps release those delicious garlicky aromas that will infuse your entire dish.
Step 3: Build the Sauce
Pour the chicken broth and half and half into the pot, stirring to combine the liquids with the garlic-infused oil. Then sprinkle in the salt, freshly ground black pepper, and garlic powder to layer the seasoning. This mixture is where your creamy, flavorful Alfredo sauce begins to take shape.
Step 4: Cook the Pasta in the Sauce
Add the uncooked fettuccini pasta directly into the pot, making sure it’s mostly submerged in the creamy liquid. Bring the mixture to a gentle boil, then lower the heat to a simmer. Keep the pot uncovered and stir occasionally to prevent sticking. Over about 10 to 12 minutes, the pasta will cook al dente, and the sauce will naturally thicken as the starches release. This step is pure magic because the pasta absorbs all those great flavors.
Step 5: Reincorporate the Chicken
Once your pasta is perfectly cooked, return the browned, spiced chicken back to the pot. Give everything a gentle stir to combine, letting the chicken warm through and meld with the creamy sauce for a couple more minutes.
Step 6: Finish with Parmesan
Remove the pot from heat and fold in the grated Parmesan cheese. It will melt into the sauce, creating a silky, cheesy finish that makes this meal so irresistible. Serve it immediately to enjoy the dish at its creamiest and most flavorful.

Garnishes
To elevate your presentation and flavor, sprinkle some extra grated Parmesan cheese and a little chopped fresh parsley or green onions. The garnish adds a pop of color that brightens up the creamy, spicy base while also giving a subtle fresh crunch.
Side Dishes

Make Ahead and Storage
Storing Leftovers
If you have leftovers, let them cool to room temperature before transferring to an airtight container. Stored properly in the refrigerator, your One Pot Cajun Chicken Alfredo Recipe will stay fresh for up to 3 days, allowing you to enjoy its creamy goodness again with minimal effort.
Freezing
This dish freezes well but with a slight change in texture due to the creamy sauce. For best results, freeze leftovers in a freezer-safe container for up to 2 months. When ready to eat, thaw overnight in the refrigerator before reheating gently to preserve creaminess.
Reheating
Reheat in a skillet over low heat, stirring frequently and adding a splash of milk or broth if the sauce becomes too thick. This method helps revive the velvety Alfredo texture without drying out the chicken or pasta.
FAQs
Can I use thighs instead of chicken breasts?
Absolutely! Boneless, skinless chicken thighs would add a bit more juiciness and depth of flavor, making your One Pot Cajun Chicken Alfredo Recipe even more tender and indulgent.
Is it possible to make this recipe dairy-free?
Yes! Substitute the half and half with coconut milk or a creamy plant-based milk, and use a dairy-free Parmesan alternative to keep the creamy texture and bold flavor intact.
Can I make this recipe spicier?
Definitely. Feel free to increase the Cajun seasoning or add a pinch of cayenne pepper while cooking. This dish is versatile and welcomes a bit of extra heat to suit your palate.
What pasta can I use if I don’t have fettuccini?
While fettuccini is ideal for coating with creamy sauce, any long pasta like linguine, pappardelle, or even penne would work well in this recipe.
How do I prevent the pasta from sticking?
Make sure to stir occasionally while simmering the pasta, and ensure it stays mostly covered with liquid. This helps the pasta cook evenly and prevents sticking to the bottom of the pot.
