Chili's Copycat Cajun Chicken Pasta Recipe: Celery-Crusted Crunch Meets Spicy Creamy Sauce

This Chili's copycat Cajun chicken pasta brings the restaurant's signature creamy, spicy sauce and celery-crusted chicken right to your kitchen—restaurant-quality without the markup. 💛 Growing up in small-town Georgia, I learned that great food starts with bold flavors and a few key techniques, and this dish delivers exactly that.

The secret lies in properly browning the chicken and building the sauce from scratch, layering spices and cream for that unmistakable tangy heat.

The recipe begins with crispy celery-crusted chicken—tender inside, perfectly seasoned, and coated in a light, crunchy batter that holds up through the creamy sauce. Meanwhile, the sauce simmers until thick and velvety, balancing heat from cayenne and paprika with the richness of cream and chicken broth.

It’s the kind of dish that feels indulgent but comes together in under 45 minutes, making it perfect for weeknight dinners when you crave something hearty and flavorful.

By the time you twirl that first forkful, you’ll taste the creamy, spicy sauce clinging to perfectly cooked pasta, with each bite delivering tender chicken and that signature celery crunch. The dish is bold enough to stand alone but pairs beautifully with garlic bread or a simple side salad.

This is the version of Cajun chicken pasta that’ll have your family asking for seconds—and wondering why they ever ordered takeout.

Ready to recreate the experience? Let’s break down the steps to ensure every element—from the crispy chicken to the perfectly balanced sauce—comes together just like the restaurant’s. The key is precision, not complexity, so even if you’re new to copycat recipes, this one’s foolproof.

Ingredients for chili's copycat cajun chicken pasta

Bold flavors, crispy crunch, and creamy sauce—this copycat brings restaurant magic home with just 15 ingredients.

The chicken cutlets are the star, so boneless, skinless breasts are non-negotiable—they stay tender while the celery crust gets crispy. Pound them to even thickness (about 1/4-inch) so they cook uniformly. For the celery, fresh is best—no frozen or canned. I grab mine from the produce section at Whole Foods or any well-stocked grocery store, but even the sad plastic containers at Kroger work if you rinse and chop it right. The key is to chop it finely, almost like confetti, so it blends into the batter without chunks. Pre-shredded celery? Skip it—it’s too wet and won’t crisp up.

No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch, but the flavor won’t be identical. Short on heavy cream? Half-and-half with a splash of whole milk keeps the sauce creamy, though it’ll be slightly lighter. The chicken broth can be low-sodium or homemade—just taste it first and add salt if needed. For the pasta, fettuccine is traditional, but linguine or pappardelle also work. Just don’t go too wide—you want the sauce to cling. And if you’re feeling fancy, truffle oil in the sauce adds a luxurious touch (start with 1/2 tsp).

This dish reheats like a dream—just add a splash of water or broth to loosen the sauce. Keeps for 3 days in the fridge, but honestly, it’s better fresh. For leftovers, store in airtight containers with a layer of plastic wrap pressed against the sauce to prevent a skin from forming. Freezes beautifully for up to 2 months, though the celery crust might get soggy if thawed. To serve, I always toss with extra fresh parsley and Parmesan—it’s the little details that make it feel restaurant-worthy.

Step-by-step instructions for Cajun chicken pasta with celery-crusted crunch

Here's how to recreate Chili's signature dish at home—crispy celery crust meets rich, spicy cream sauce.

In a food processor, pulse the 1 whole celery stalks until you get a fine, wet pulp—about ½ cup total. Transfer this to a mixing bowl and whisk in the 1 cup all-purpose flour, 1.5 tsp kosher salt, 1 tsp paprika, 0.5 tsp cayenne pepper, and 0.5 tsp ground black pepper. The mixture should resemble coarse sand with visible celery flecks.

This celery crust is what gives the dish its signature crunch and subtle celery flavor. I like to use fresh celery here—it adds a nice bright note that dried celery powder can't match. If your processor struggles with the celery, chop it finely by hand first. The texture matters: you want it coarse enough to create crunch but fine enough to stick to the chicken.

Pound the 1.5 lb boneless, skinless chicken breast cutlets to an even ½-inch thickness between two sheets of plastic wrap. This ensures even cooking and maximum crispiness. Dip each cutlet into the 2 whole large eggs (beaten with a fork in a shallow bowl), letting excess drip off, then press into the celery-flour mixture, coating both sides completely.

Heat 2 tbsp unsalted butter in a large skillet over medium-high heat until foaming. Add the coated cutlets and cook for 3-4 minutes per side until golden brown and the internal temperature reaches 165°F. The celery crust should be crisp and crunchy—don't skip this step. If the crust browns too quickly, reduce heat slightly to prevent burning. Transfer the chicken to a plate and tent with foil to keep warm.

Bring a large pot of salted water to a rolling boil and cook the 12 oz fettuccine pasta for 1 minute less than package instructions. You want it al dente—it'll finish cooking in the sauce. Reserve 1 cup pasta water before draining, then return the pasta to the pot off heat and toss with 2 tbsp unsalted butter to prevent sticking.

Here's the thing—this pasta water is liquid gold. It contains starch that helps emulsify the sauce later. I always reserve more than I think I'll need because you can always add it back later if the sauce gets too thick. Don't rinse the pasta either; that starch is what makes the sauce cling beautifully to each strand.

In the same skillet (don't wipe it clean—those browned bits are flavor), melt 2 tbsp unsalted butter over medium heat. Add the 4 cloves garlic cloves (minced) and sauté for 30 seconds until fragrant. Pour in the 1.5 cups chicken broth and scrape up any browned bits from the bottom of the pan. Bring to a simmer and cook for 2 minutes to reduce slightly.

Lower heat to medium-low and stir in the 1 cup heavy cream, 0.5 cup parmesan cheese, 0.5 tsp cayenne pepper, and 0.5 tsp ground black pepper. Simmer for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. If it gets too thick, add pasta water 1 tablespoon at a time until you reach a velvety consistency. This sauce should be rich but still coat the pasta lightly—not heavy enough to smother the fettuccine.

Add the cooked chicken cutlets and fettuccine to the sauce, tossing gently to combine. Let it simmer together for 1-2 minutes so the chicken absorbs some of the creamy sauce. Divide the pasta among plates, top each serving with ¼ cup fresh parsley (chopped), and serve immediately while the celery crust is still crisp.

Real talk: this dish is best served fresh off the stove. The celery crust loses its crunch as it cools, and the sauce thickens further. I like to serve it with extra parmesan on the side and a simple arugula salad to cut through the richness. The combination of crispy, creamy, and spicy flavors is what makes this copycat version so worth recreating at home.

Creative variations of this dish

Spicy Cajun Twist

For a bolder kick, add 1 tbsp hot sauce (like Tabasco) or ½ tsp smoked paprika directly to the sauce. I like to use Cholula for its smoky depth—it balances the creaminess beautifully.

For extra heat, sprinkle ½ tsp cayenne pepper on top of each serving before plating. This version is perfect for spice lovers who still want that creamy, comforting base. 🌶️

Creamy White Wine Version

Swap the heavy cream for 1 cup dry white wine (like Sauvignon Blanc) and reduce it by half before adding the chicken broth. This lighter version has a bright, citrusy note that pairs wonderfully with the celery crust.

I add 1 tbsp lemon juice at the end for extra zing. It’s a fantastic alternative for those who prefer less richness but still crave bold flavors.

Protein Swaps

Need a different protein? Swap the chicken for shrimp (peeled and deveined) or chicken thighs for extra juiciness. For shrimp, toss them in the celery crust and cook for just 2-3 minutes per side—they’re done when opaque.

For a vegetarian version, replace the chicken with 12 oz extra-firm tofu (pressed and sliced into cutlets). Toss the tofu in the celery crust and pan-fry until golden. Add 1 cup sliced mushrooms and 1 zucchini (diced) to the sauce for extra texture.

This version keeps the creamy, spicy profile while adding hearty veggies. It’s a great way to keep the dish satisfying without meat. 🥦

Gluten-Free Adaptation

Use 1 cup gluten-free all-purpose flour (like Bob’s Red Mill 1:1>) for the celery crust, and ensure your pasta is certified gluten-free. The texture will be slightly different—more delicate—but the flavors remain rich and satisfying.
