This Chili's copycat cajun chicken pasta recipe is delicious! The Cajun chicken breast is so flavorful, juicy, and tender, while the homemade alfredo sauce is both creamy and silky smooth, and not at all gritty.
What is Cajun Chicken Pasta
It's a penne pasta dish served with creamy melt-in-your-mouth alfredo sauce and cajun chicken breast.
The Ingredients to Make the Creamiest Penne Pasta with Chicken and Alfredo Sauce:
To make this cajun chicken alfredo pasta, you will need only a few simple ingredients. Here's an overview of what you'll use:
- Chicken breast. Find chicken breasts that aren't too big, 8-9 oz per piece is a perfect size.
- Cajun seasoning. You can use store-bought or homemade Cajun seasoning. In this recipe, I used this homemade cajun seasoning with no added salt.
- Penne pasta
- Heavy whipping cream
- Freshly grated parmesan cheese. Be sure to use fresh block parmesan cheese and grate it at home. Do not use pre-grated parmesan cheese, like from Kraft to avoid grainy alfredo sauce.
- Fresh garlic
- Unsalted butter
- Lemon zest
- Salt and black pepper to taste

How to Make Cajun Chicken Pasta:
This cajun chicken pasta with alfredo sauce recipe is easy and very inexpensive to make. It requires multiple steps but not complicated. So, here are some important steps to follow:
Step 1. Marinate the Chicken Breast
- Trim any membranes or fat from the breasts with a knife.
- Working with 1 chicken breast at a time, place inside a gallon zip-top bag and seal the bag, pressing out as much air as possible. Use a meat mallet, rolling pin, saucepan, or skillet to slightly flatten the breast to an even thickness from end to end, between ¼ to ½-inch.
- Season the chicken with 1 tablespoon of cajun seasoning and ½ teaspoon of kosher salt (skip the salt if you are using a store-bought cajun seasoning). Marinate in the fridge for 15-30 minutes.
Step 2. Cook pasta according to package instructions
Step 3. Cook Cajun Chicken Breast
- To start, pre-heat a grill pan to high heat for about 3-5 minutes.
- Next, lower the heat to medium-high and lightly grease the pan with oil or cooking spray.
- After that, add the chicken breasts to the pan and cook for 5-6 minutes on the first side without moving until it developed nice grill marks.
- Last, flip the chicken breast and continue cooking for 5-6 minutes or until the internal temperature reaches 165°F. Set aside and let it rest.
Or you can bake the cajun chicken breast in the oven at 425° for about 15-18 minutes depending on the thickness or until the chicken is cooked through and no longer pink.
Step 4. Make the Alfredo Sauce
Perfect Alfredo sauce requires the right technique with the best ingredients. Make sure that you have everything ready before you start cooking. Also, use fresh parmesan cheese instead of pre-shredded/grated cheese then bring it to temperature by letting it sit on the counter for 15 minutes.
- First, melt butter in a saucepan over medium heat. Add garlic and cook just until fragrant for about 30 seconds to 1 minute.
- After that, gradually add heavy cream and lemon zest. Cook, continue whisking constantly for about 2 minutes or until slightly thickened.
- Next, reduce the heat to the lowest heat and slowly add freshly grated parmesan and continue stirring until the cheese is melted and the sauce thickens to coat the back of a spoon. Season with salt and pepper if necessary.
