Copycat Chili’s Cajun Chicken Pasta

Prep time: 15 min Cook time: 25 min Servings: 4

Chili’s Cajun Chicken Pasta is one of those dishes that keeps people coming back. Thick-cut penne tossed in a spicy cream sauce with seared Cajun chicken, colorful bell peppers, and a generous hit of Parmesan. It hits every craving — creamy, spicy, savory, and filling.

This recipe comes together in about 40 minutes, which is often faster than the drive to Chili’s, the wait for a table, and the time spent flagging down your server. Everything cooks in one skillet (aside from the pasta pot), and the technique is straightforward enough for a weeknight dinner.

The Cajun seasoning is the backbone of this dish. It brings paprika, garlic, oregano, and cayenne together in a way that gives the chicken a deep, complex crust without requiring a dozen individual spice jars. If you have a favorite Cajun blend, use it. If not, any grocery store brand works fine here.

Why Make It at Home?

Chili’s prices this dish at $16.49 as of early 2026. Add a drink and tip and you’re past $25 per person. This homemade version costs about $5 per serving. A pound and a half of chicken runs $6-8, a box of penne is $1.50, heavy cream is about $4, and the vegetables and cheese add another $4-5. The whole pot feeds four generously for under $20.

You also get to control the spice level precisely. The restaurant version is fairly mild to appeal to a broad audience. At home, you can push the Cajun seasoning harder or add crushed red pepper flakes for real heat.

What Makes Chili’s Cajun Chicken Pasta So Good

The sauce walks a careful line between rich and light. Heavy cream gives it body, but the chicken broth thins it just enough so it coats the penne without turning the dish into a bowl of liquid cheese. The Parmesan melts into the sauce and adds a salty, nutty undertone that complements the Cajun spice rather than competing with it. Getting this balance right means simmering the sauce until it reduces slightly — about 5-6 minutes — before adding the cheese.

The chicken gets seared hard in a hot skillet, which builds a dark Cajun crust packed with flavor. Cooking the chicken whole and slicing after resting keeps the interior juicy. Cutting before cooking would dry out thin pieces and wash the seasoning off into the pan. Resting for five minutes lets the juices redistribute, so each slice stays moist when it hits the sauce.

Bell peppers and onion add sweetness and crunch that balance the richness of the cream sauce. Chili’s uses both red and green peppers, and the color contrast makes the dish look as good as it tastes. The tomatoes go in raw at the end, which gives them just enough warmth to release their juice without turning them into mush.

Tips & Variations

• Pound the chicken even. Use a meat mallet or rolling pin to flatten the thickest parts of the breast to uniform thickness. This prevents thin edges from overcooking while the center finishes.

• Don’t boil the cream sauce. Keep it at a gentle simmer. Boiling can cause the cream to break and turn grainy, especially after adding the Parmesan.

• Add mushrooms. Slice 8 oz of cremini mushrooms and saute them with the peppers for an earthy layer that works well with the Cajun spice.

• Make it with shrimp. Swap the chicken for 1.5 lbs of large shrimp. Season and sear them for 2-3 minutes per side instead of 6-7.

• Finish with a squeeze of lemon. A half lemon squeezed over the finished dish brightens the cream sauce and cuts through the richness.

Storage & Reheating

This pasta stores well in the fridge for up to 3 days. The sauce will thicken as it cools because the cheese and cream set up in the cold. When reheating, add a splash of chicken broth or milk to the pan and warm over medium-low heat, stirring frequently, until the sauce loosens back up.

Microwave reheating works in a pinch — add a tablespoon of water, cover loosely, and heat in 90-second intervals, stirring between each. Freezing is not recommended for this dish. The cream sauce tends to separate and become grainy when thawed, and the pasta overcooks during reheating. If you want to meal prep, freeze the cooked chicken and sauce separately from the pasta, then cook fresh penne when you’re ready to eat.
