One Pan Cajun Chicken Alfredo

There are few things in life that deliver pure comfort faster than a creamy bowl of pasta — and this One Pan Cajun Chicken Alfredo does it in under 30 minutes. It’s rich, spicy, and cozy all at once, which is probably why it’s one of my absolute favorites. The creamy Alfredo sauce meets that little Cajun kick and… yum. It’s like date night and comfort food had a delicious baby.

Why You’ll Love It

• One pan, zero stress. Everything cooks together — chicken, pasta, sauce — which means fewer dishes (and less judgment from your dishwasher).
• Creamy + spicy = perfection. The Alfredo sauce balances out the Cajun seasoning beautifully.
• Quick enough for weeknights. From fridge to fork in under 30 minutes.
• Crowd favorite. Even picky eaters go back for seconds.

Ingredients

• 1 pound boneless, skinless chicken breast, cut into bite-size pieces
• 2 tablespoons butter
• 2 teaspoons Cajun seasoning, divided
• 2 teaspoons minced garlic (about 2-3 cloves)
• 2 cups chicken broth
• 1 ½ cups half and half
• 1 teaspoon salt
• 1 teaspoon ground black pepper
• ½ teaspoon garlic powder
• 8 ounces uncooked fettuccine pasta
• ¾ cup grated Parmesan cheese

Instructions

1. Cook the chicken: Heat butter in a dutch oven or large pot over medium-high heat. Add your chicken pieces and 1 teaspoon of Cajun seasoning. Cook for about 5–7 minutes, stirring now and then, until the chicken is no longer pink and reaches an internal temp of 165°F. Stir in the minced garlic and cook for another minute until fragrant.
2. Build the sauce: Pour in the chicken broth, half and half, and the remaining Cajun seasoning. Add salt, black pepper, and garlic powder, then stir to combine. Add the uncooked pasta (break it in half if you’d like) and give everything a good stir so the noodles are covered.
3. Let it all cook together: Cover and bring to a boil, then remove the lid and reduce the heat to medium-low. Continue cooking for 10–12 minutes, stirring frequently so the pasta doesn’t clump. You’ll know it’s ready when the noodles are tender and most of the liquid has been absorbed — you want just a little saucy goodness left at the bottom.
4. Cheese, please: Remove from heat, stir in the grated Parmesan until melted and creamy, and that’s it! Serve it right away — no one likes waiting for Alfredo.

Pro Tips

• Stir often while the pasta cooks — it helps prevent sticking and keeps the sauce smooth.
• Sauce too thick? Just add a splash of chicken broth, milk or pasta water to loosen it up.
• Want it extra spicy? Add a pinch more Cajun seasoning or a few red pepper flakes.
• Don’t skip the Parmesan — it ties the whole dish together.

Pairing Suggestions

• Garlic bread – because carbs on carbs is always a good life choice.
• Simple side salad – something fresh and crisp to balance all that creamy goodness.
• Roasted veggies – asparagus, broccoli, or even zucchini pair beautifully.

Favorite Tools Used

• Dutch Oven – the hero of any one-pan meal.
• Tongs – makes flipping chicken and tossing pasta so much easier.
• Wooden spoon – for stirring without scratching your pan.
• Cheese grater – freshly grated Parmesan melts like a dream.
