Ingredients for chili’s copycat cajun chicken pasta
Restaurant-quality Cajun crunch and creamy tomato hug start with these 15 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Chicken Breast 🍗 | 1 ½ lb | Cut into 1-inch pieces |
| Medium Yellow Onion 🧅 | 1 whole | Diced, about 1 cup |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Cajun Seasoning 🌶️ | 2 tbsp | Store-bought or homemade blend |
| All-Purpose Flour 🌾 | ½ cup | For coating chicken pieces |
| Unsalted Butter 🧈 | ½ cup | Full-fat for best flavor |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Tomato Paste 🍅 | ¼ cup | Smooth, not chunky |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Fennel Seeds 🌾 | ½ tsp | Lightly toasted for aroma |
| Fettuccine Pasta 🍝 | 12 oz | Or other medium pasta |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The chicken is your star—boneless, skinless breasts work best for even cooking. Grab freezer-burned-free chicken from Costco or your local butcher for the freshest cut. The Cajun seasoning matters too: Tony Chachere’s is the gold standard, but any blend with paprika, cayenne, and garlic powder works. Toast your fennel seeds in a dry pan for 30 seconds—they add a subtle licorice note that elevates everything. For the pasta, Barilla or De Cecco hold up best to the rich sauce without turning mushy.
No Cajun seasoning? Mix 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne, and 1/2 tsp dried oregano. Short on butter? Olive oil works in a pinch, though it won’t give the same richness. The tomato paste can be the squeeze-tube kind from Trader Joe’s—it’s perfect for this recipe and lasts forever. For the broth, low-sodium is key so you don’t over-salt the dish. The lemon juice brightens everything—don’t skip it, even if you’re not a fan of citrus in pasta.
This sauce gets better the next day, so make extra if you’re feeding a crowd. Store leftovers in the fridge for 4-5 days or freeze for 3 months. I always double the chicken and sauce when I make this—lunches for the week sorted. The pasta reheats best with a splash of water or broth to loosen it up. For crispy chicken every time, pat the pieces dry before coating them in flour.

Step-by-step instructions for Chili’s copycat Cajun chicken pasta
Here’s how to recreate that signature restaurant flavor at home—rich, creamy, and packed with spice-crusted chicken.
Prepare the Chicken for Maximum Crunch
Cut the 1.5 lb boneless chicken breast into 1-inch pieces. Place them in a bowl and toss with 2 tbsp cajun seasoning and 1.5 tsp salt until fully coated. Here’s the thing—this seasoning step is crucial. Let the chicken sit for 10 minutes while you prep the rest. This gives the spices time to adhere and develop flavor.
After resting, dredge each piece in 0.5 cup all-purpose flour, pressing gently to ensure an even coating. Shake off any excess flour—you want a light, crispy crust, not a heavy batter. The flour will create that signature crunch we’re after. Arrange the floured chicken on a plate and set aside.
Cook the Pasta and Build the Sauce Base
Bring a large pot of water to a rolling boil and add 12 oz fettuccine pasta along with 0.5 tsp black pepper. Cook until 1 minute shy of package instructions for al dente pasta. Reserve 1 cup pasta water before draining—this starchy liquid is our secret weapon for creamy perfection.
While the pasta cooks, heat 0.5 cup unsalted butter in a large skillet over medium heat. Add the diced 1 whole medium yellow onion and cook for 5 minutes until softened. Stir in the 4 minced garlic cloves and 0.5 tsp fennel seeds, toasting for 30 seconds until fragrant. This aromatic base forms the flavor foundation of our sauce.
Create the Spice-Crusted Chicken
Working in batches if needed, add the floured chicken to the skillet with the onions and garlic. Cook for 4-5 minutes per side until the chicken is golden brown and cooked through to 165°F internally. Don’t crowd the pan—this prevents proper browning. Transfer the chicken to a plate and set aside, keeping it warm.
In the same skillet, reduce heat to medium-low and stir in the 0.25 cup tomato paste. Cook for 2 minutes until slightly darkened. Pour in the 1 cup chicken broth and scrape up any browned bits from the bottom—this is where all the flavor hides. Add the 1 tsp dried thyme and let the mixture simmer for 3 minutes until slightly thickened.
Combine Everything for the Creamy Finish
Return the chicken to the skillet and stir in the 0.5 cup heavy cream. Add the drained pasta and toss everything together. The sauce should begin to coat the pasta immediately. If it’s too thick, add pasta water 1 tablespoon at a time until you reach a creamy consistency that clings beautifully to each strand.
Stir in the 1 tbsp lemon juice and taste. Here’s where you can adjust seasoning—add more cajun seasoning if you want extra heat, or a pinch more salt if needed. The lemon brightens all the rich flavors and cuts through the creaminess just enough to keep it balanced. Let the whole dish simmer together for 2-3 minutes so all the flavors meld perfectly.
Pro Tips For Making Chili’S Copycat Cajun Chicken Pasta
- SEAR CHICKEN IN BATCHES: Chicken breasts release more moisture than thighs, and crowding the pan turns your Cajun crust into a sad, greasy mess. Work in single layers—no overlapping—and resist the urge to flip too soon. The golden-brown crust happens in the first 3-4 minutes, not the last.
- MINCE ONION FINE: This isn’t a “chop roughly” recipe—you want the onion to disappear into the sauce, not sit as chunks. Pulse it in a food processor for 2 seconds at a time, or hand-chop until it’s almost paste-like. I used to skip this, and the texture always felt off.
- DEGLAZE WITH WARM BROTH: After browning chicken and onions, pour in just enough warm chicken broth (not cold) to loosen the fond. Cold liquid shocks the pan and makes it harder to scrape up those flavor-packed bits. A splash of broth + a wooden spoon works wonders—just don’t over-dilute.
- REST CHICKEN 5 MINUTES: Slice those breasts too soon, and they’ll turn to mush in the pasta sauce. Tent them with foil and let them sit while you prep the roux—even 5 minutes makes a difference. I learned this after serving rubbery chicken to guests (twice).
Make-ahead tips for this dish
Marinade Ahead
I always marinate the chicken overnight for maximum flavor penetration and tenderness. Place the 1.5 lb chicken pieces in a resealable bag with 2 tbsp Cajun seasoning, 1.5 tsp salt, and 1 tbsp olive oil.
Seal tightly and refrigerate for 12-24 hours. This step transforms tough chicken into melt-in-your-mouth perfection. Pro tip: Add 1 tbsp lemon juice to the marinade for extra brightness. 💫
Prep Sauce Base
The sauce components can be prepped a day ahead to save time. In a bowl, mix 0.25 cup tomato paste, 1 cup chicken broth, 0.5 cup heavy cream, 1 tsp dried thyme, and 0.5 tsp fennel seeds.
Store in an airtight container in the fridge. When ready to cook, simply heat this mixture in the skillet after browning the chicken. This shortcut cuts your active cooking time by 20 minutes.
Pasta Pre-Cook
For the fastest assembly, cook the pasta 1 minute less than package instructions and immediately shock it in ice water to stop cooking. Drain thoroughly and store in an airtight container with a splash of olive oil to prevent sticking.
Reheat by tossing with fresh pasta water when ready to combine with the chicken and sauce. This method keeps the pasta perfectly al dente even after reheating. ⏰
Complete Assembly
Here’s my foolproof reheating method: Combine all components in a large skillet over medium heat. Add 2 tbsp butter to prevent sticking, then add the pre-cooked pasta, chicken, and sauce mixture. Heat for 5-7 minutes until everything is piping hot.
The residual heat from the pan will finish cooking the pasta perfectly. For extra crunch, add 1 tbsp flour to the chicken pieces before reheating.
Freezer-Friendly
This dish freezes beautifully for up to 3 months. Assemble completely, then divide into portioned containers with parchment paper between layers to prevent sticking. Thaw overnight in the fridge, then reheat in the skillet as directed.
The texture remains excellent, though the chicken crust may lose some crispness. For best results, reheat only what you plan to eat immediately and store the rest separately. 🍲
Garnish Fresh
Always add fresh garnishes after reheating to maintain vibrant presentation. I recommend chopped parsley, grated Parmesan cheese, and a sprinkle of red pepper flakes for color and flavor.
The parsley adds freshness while the cheese and pepper flakes enhance the Cajun profile. Keep these garnishes separate until serving to preserve their freshness and visual appeal. 🌿

Frequently asked questions
Why does this recipe use heavy cream instead of milk?
The heavy cream creates that signature velvety texture found in Chili’s version. It adds richness and helps the sauce cling beautifully to the pasta. You can substitute with half-and-half if needed, but the dish will be slightly lighter. For a dairy-free option, coconut cream works well but may alter the flavor slightly.
Can I make this dish without a skillet?
Use a large oven-safe pot with a tight-fitting lid. Cook the chicken on medium-high heat until golden, then cover and let it steam for 2-3 minutes to finish cooking. The pasta can be cooked directly in the pot after browning the chicken. Just be sure to deglaze thoroughly to capture all the flavor.
How do I adjust the spice level for kids or sensitive eaters?
Start by reducing the Cajun seasoning to 1 tbsp total instead of 2. For extra mildness, omit the cayenne from any homemade spice blends. You can also serve the chicken and sauce separately so kids can enjoy the pasta without the spice. Always taste and adjust gradually—this sauce is forgiving!
What’s the best way to store leftovers?
Store in an airtight container with parchment paper between layers to prevent sticking. Keep for 4-5 days in the fridge or freeze for up to 3 months. When reheating, add 1-2 tbsp pasta water or broth to restore creaminess. Never reheat in the microwave—use a skillet over medium heat for best results.
Can I use ground chicken instead of breast?
Ground chicken works but will require different cooking times—aim for 5-6 minutes total to avoid drying out. The texture will be more tender than crispy, but the flavor remains excellent. For best results, keep the pieces slightly larger than typical ground chicken to help them hold their shape.
