Ingredients You’ll Need
Keeping things simple is the key to letting each flavor shine in this recipe. Every ingredient plays an essential role, from the spicy Cajun seasoning that brings that signature zest, to the creamy half and half that creates the silky sauce texture. Here’s what you’ll want to gather before you start:
- Chicken breast, 1 pound: Cut into bite-sized pieces for quick, even cooking and perfect tenderness.
- Olive oil, 2 tablespoons: Adds a subtle fruitiness and is perfect for searing the chicken to golden perfection.
- Cajun seasoning, 2 teaspoons: This bold blend infuses the chicken with that classic Louisiana spice and smokiness.
- Minced garlic, 2 teaspoons: Fresh garlic enhances the aroma and gives the sauce an inviting depth.
- Chicken broth, 1 ½ cups: The flavorful liquid base that helps cook the pasta and enriches the sauce.
- Half and half, 1 cup: Provides that creamy, luscious texture without being too heavy.
- Salt, 1 teaspoon: Balances and amplifies the flavors throughout the dish.
- Ground black pepper, 1 teaspoon: Introduces a subtle heat that harmonizes with the Cajun spice.
- Garlic powder, ¼ teaspoon: A little extra garlic punch to complement the fresh minced garlic.
- Fettuccini pasta, 8 ounces uncooked: The star noodle that soaks up the sauce perfectly, delivering satisfying bite.
- Grated Parmesan cheese, ½ cup: The finishing touch that melts into the sauce for an irresistible, cheesy richness.
How to Make One Pot Cajun Chicken Alfredo Recipe
Step 1: Brown the Chicken
Start by heating olive oil in a large pot or deep skillet over medium-high heat. Toss your chicken pieces in the Cajun seasoning, ensuring every bite is packed with flavor. Sear the chicken until it’s a beautiful golden brown and cooked through, which usually takes about 5 to 7 minutes. Once done, remove the chicken from the pot and set it aside for now.
Step 2: Sauté the Garlic
In the same pot, you’ll add the minced garlic next. Sauté it for just about a minute — this quick step releases that aromatic garlicky goodness you can’t resist. Be careful not to burn it, as you want it fragrant and mellow.
Step 3: Build the Sauce Base
Now pour in the chicken broth and half and half. Give everything a good stir so the liquids combine nicely. Season with salt, black pepper, and garlic powder to layer in additional savory notes and a subtle depth of flavor that complements the Cajun heat.
Step 4: Cook the Pasta
Add the uncooked fettuccini right into the pot, making sure it’s mostly submerged in the liquid mixture. Bring everything to a gentle boil, then turn the heat down and let it simmer uncovered. Stir occasionally so the pasta doesn’t stick and to help the sauce thicken. This process takes about 10 to 12 minutes, enough time for your noodles to cook to a perfect al dente.
Step 5: Reintroduce the Chicken
Once your pasta is cooked and the sauce has thickened beautifully, it’s time to toss the chicken back into the pot. Stir gently so every bite gets a delicious hit of that spicy, creamy goodness.
Step 6: Finish with Parmesan
Finally, remove the pot from heat and sprinkle in the grated Parmesan cheese. Stir until the cheese melts completely and the sauce becomes irresistibly creamy, wrapping every noodle and chicken bite in decadent flavor.
Step 7: Serve Immediately
This dish is best enjoyed fresh and hot — the flavors are most vibrant and the sauce is dreamily smooth right off the stove. Get ready for some serious compliments!
How to Serve One Pot Cajun Chicken Alfredo Recipe

Garnishes
Add a sprinkle of extra grated Parmesan or freshly chopped parsley for a pop of color and freshness. A few cracks of fresh black pepper on top can also elevate the dish’s flavor and presentation instantly.
Side Dishes
Pair this hearty Cajun chicken Alfredo with a simple green salad dressed with lemon vinaigrette to cut through the richness. Roasted or steamed vegetables like broccoli or asparagus also make excellent companions for an all-around balanced meal.
Creative Ways to Present
Serve your One Pot Cajun Chicken Alfredo Recipe in a rustic cast-iron skillet or an oversized pasta bowl for that cozy homemade vibe. For a fun twist, you can sprinkle some crispy bacon bits or toasted pine nuts on top for added texture and surprise.
Make Ahead and Storage
Storing Leftovers
Transfer any uneaten portions into an airtight container and store them in the refrigerator for up to 3 days. This keeps the creamy sauce intact and the chicken tender.
Freezing
While the sauce and pasta combination freezes okay, it’s best to freeze the chicken separately if possible to maintain texture. When freezing the whole dish, use a freezer-safe container and consume within 1 month for best quality.
Reheating
To reheat, warm leftovers gently on the stove over low heat, stirring frequently to prevent the sauce from separating. Adding a splash of milk or broth can help rejuvenate the creamy consistency.
FAQs
Can I use a different type of pasta for this recipe?
Absolutely! While fettuccini is classic for Alfredo, feel free to swap in penne, linguine, or even rigatoni. Just remember to adjust cooking times, as some pastas take longer to cook than others.
Is this recipe very spicy because of the Cajun seasoning?
The Cajun seasoning adds a noticeable but balanced kick — think flavorful warmth rather than overpowering heat. If you prefer milder flavors, simply reduce the amount of seasoning or use a mild Cajun blend.
Can I make this dish dairy-free?
Yes, you can substitute half and half with a creamy non-dairy milk like coconut milk or cashew cream, and choose a dairy-free Parmesan alternative. Keep in mind this may slightly change the flavor but will still be rich and delicious.
What’s the best way to get the sauce thick and creamy?
Simmering uncovered and stirring frequently helps the sauce reduce and thicken naturally. Also, finishing with freshly grated Parmesan cheese is key to that irresistibly creamy texture.
Can I use pre-cooked chicken in this recipe?
You can, but since this is a one-pot recipe designed to cook chicken fresh with the seasoning, using pre-cooked chicken means you’ll add it at the end just to warm through. Adjust seasoning accordingly to keep the bold Cajun flavors.
