  • Unsalted butter
  • Yellow onion, diced
  • Garlic, minced
  • Heavy cream
  • Lemon zest
  • Parmesan
  • Kosher salt
  • Freshly ground black pepper

  • Parmesan

You can cook the penne ahead of time and reheat it in simmering water for about 30 seconds before using it in this recipe. 

You can use any fresh plum tomatoes you prefer in this recipe, but Roma tomatoes are probably the most common ones you will find. Do not use canned tomatoes.

How to Make Chili’s Cajun Chicken Pasta

Here are the steps for making this copycat Chili’s Cajun chicken pasta recipe. Note there’s a printable recipe card below.

To cook the chicken:

  1. Trim the chicken breasts to remove any extra fat or skin, and use paper towels to pat them dry.
  2. Liberally sprinkle the chicken breasts with the Cajun seasoning. 
  3. Heat a large pan over medium-high heat. When the pan is hot, add the olive oil and wait until it starts to shimmer. 
  4. Carefully place the chicken breasts in the pan. Cook on the first side for 6 to 7 minutes. Turn over and cook for another 5 to 6 minutes or until the internal temperature reaches 165 degrees. 
  5. Transfer the chicken to a plate and cover it with aluminum foil to keep it warm.

To make the sauce:

  1. Dice the onions and mince the garlic. Put aside for later. 
  2. Return the same pan you used to cook the chicken to the stove. Using the same pan will save you from additional cleaning and add a ton of flavor to your sauce. 
  3. Melt the butter over medium heat and saute the diced onions until barely translucent. 
  4. Add the garlic and cook for about a minute before whisking in the heavy cream, lemon zest, and grated parmesan. 
  5. Continue whisking until the cream mixture begins to bubble and thickens. 
  6. Season the sauce with salt and freshly ground black pepper.

Recipe Variation

Try making this dish with grilled or sauteed shrimp or andouille sausage. Combining shrimp, chicken, and andouille sausage will give the pasta a more authentic Cajun flavor. 

Several ingredients that are wonderful additions to this recipe include:

  • Green bell peppers
  • Chipotle peppers
  • Mushrooms
  • Celery
  • Other vegetables (broccoli, cauliflower, or zucchini)

What to Serve With Cajun Chicken Pasta

The sauce is so good that you will want some sort of bread to mop up any leftovers. French bread or dinner rolls will work fine, but if you have time, think about making Commanders Palace’s famous Garlic Bread for the ultimate dinner combination.

A simple green salad or some steamed or roasted veggies would be great sides for the dish.

How to Store Leftover Cajun Chicken Pasta 

Keep cooked pasta, sauce, chicken, and garnishes in separate airtight containers in the fridge for up to three days. 

How to Reheat Chilis Cajun Chicken Pasta

Reheat the cooked chicken strips with the sauce over low heat while frequently stirring to prevent the sauce from scorching. You may want to add extra heavy cream or milk to the sauce to thin it out a little before reheating. Heat the cooked pasta in simmering water.
