Step-by-step: Copycat Chili’s Cajun Chicken Pasta
Time the steps so the pasta finishes as the sauce reaches its glossy finish. Read each short section before you start — multitasking is rewarded here.
Step 1 — Prep and season the chicken
Pat the chicken dry with paper towels. Toss the strips with the Cajun seasoning, a pinch of salt, and a few grinds of black pepper so every piece is well coated.
Tip: If you like a deeper crust, let the seasoned chicken rest for 10–15 minutes at room temperature before cooking. It helps the spices adhere and gives you a better sear.
Step 2 — Cook the pasta
Bring a large pot of salted water to a rolling boil and cook the penne according to package directions until just shy of al dente (about 1 minute less than recommended). Reserve 1 cup of pasta water, then drain the pasta and set aside.
Step 3 — Brown the chicken
Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the chicken in a single layer and don’t crowd the pan — work in batches if necessary.
Let the strips sear undisturbed for 2–3 minutes, flip and cook another 1–2 minutes until cooked through. Remove chicken to a plate; it will finish in the sauce so avoid overcooking.
Step 4 — Build the sauce
Lower heat to medium, add butter and 1 tbsp olive oil to the same pan. Add onion and bell peppers and sauté until softened and fragrant, about 4–5 minutes.
Stir in garlic, smoked paprika, and cayenne and cook 30 seconds. Pour in chicken broth and scrape any browned bits from the pan with a wooden spoon.
Pour in heavy cream and bring to a gentle simmer. Let the mixture reduce slightly, about 3–4 minutes, until it begins to thicken.
Step 5 — Finish with cheese and combine
Lower the heat and whisk in the Parmesan cheese a little at a time so the sauce becomes silky. If it’s too thick, add pasta water a splash at a time until the consistency coats the back of a spoon.
Return chicken to the skillet along with the cooked penne and toss to combine. Adjust seasoning with salt, black pepper, and lemon juice to brighten the flavors.
Step 6 — Serve
Spoon into warm bowls, scatter with chopped parsley and extra Parmesan. The sauce should cling to the pasta, the chicken should be juicy, and the peppers give a sweet snap with every bite.
Why this version stands out
I wanted to capture Chili’s balance of creamy and bright without loading the dish with butter alone. Using a bit of chicken broth to temper the cream keeps the sauce luscious but not heavy.
The quick sear on the chicken plus a touch of smoked paprika echoes that grilled flavor you get at the restaurant. Fresh lemon at the end lifts the dish so it never feels cloying.
Ingredient spotlight & smart swaps
Penne is the classic choice because its ridges and tubes hold sauce, but rigatoni or ziti also work well. If you prefer a lighter dish, swap half-and-half for heavy cream and reduce the Parmesan by a few tablespoons.
Don’t have Cajun seasoning? Mix 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp dried oregano, 1/2 tsp thyme, 1/2 tsp cayenne, and 1/2 tsp black pepper for a close stand-in.
Make-ahead, storage, and reheating
This pasta is great for make-ahead meals. Store in an airtight container in the fridge for up to 3 days. The sauce firms a bit when chilled, so loosen it with 2–4 tbsp milk or cream when reheating.
Reheat gently in a skillet over medium-low heat with a splash of broth or milk, stirring until the sauce loosens. Avoid the microwave for best texture, but use it in a pinch—stir halfway through and add a little liquid.
Serving suggestions and variations
Serve with a simple green salad and crusty bread to mop up extra sauce. For a smoky twist, toss browned andouille sausage slices into the pan with the peppers.
To make it lighter, swap chicken for shrimp (cook 2–3 minutes per side) and use half-and-half plus a tablespoon of cornstarch slurry to thicken the sauce.
Common mistakes and how to avoid them
Overcooking the chicken is the usual culprit; pull it from the pan a touch early because it’ll finish in the sauce. Undersalting the pasta water makes the whole dish taste flat—season it like the sea.
Throwing cheese into boiling cream can cause clumping. Reduce heat and whisk cheese in gradually so it melts smoothly.
FAQ — Copycat Chili’s Cajun Chicken Pasta
Can I use pre-shredded Parmesan?
Pre-shredded cheese often has anti-caking agents that prevent smooth melting. It’ll still work, but for the creamiest finish use freshly grated Parmesan.
How spicy is this recipe? Can I make it milder?
The heat is moderate with the suggested amounts. Reduce or omit cayenne and use a mild paprika instead to tone it down. You can always add hot sauce at the table.
Can I make this gluten-free?
Yes—swap the penne for your favorite gluten-free pasta and check your chicken broth and Cajun seasoning labels for hidden gluten. Cook the pasta according to its package instructions.
Is there a lower-calorie version that still tastes good?
Use half-and-half or a mixture of milk and a touch of cream, reduce the cheese, and use skinless chicken thighs for flavor with less dried-out texture. Add more vegetables to increase volume without many calories.
How do I prevent the sauce from breaking?
Keep the sauce at a gentle simmer—not a rolling boil—and add cheese off the heat or on very low heat. If it does separate, whisk in a tablespoon of cold water or a splash of milk to bring it back together.
