Cajun Chicken Pasta
This Cajun Chicken Pasta features tender chicken, bold spices, and a velvety cream sauce that clings to every penne ridge.
- Searing the chicken separately prevents overcooking and preserves its juicy, tender interior.
- Deglazing the pan with chicken broth lifts the browned bits (fond), packing the sauce with deep, caramelized flavor.
- Starch from the pasta water acts as a natural emulsifier, binding the heavy cream and cheese into a velvety glaze.
The first time I attempted a Cajun pasta was in my cramped college apartment, where the smoke detector was so sensitive it would go off if I even thought about searing meat. I ended up setting off the entire building's alarm while trying to blacken chicken in a cheap, thin aluminum pan that warped the second it touched the coil, which got annoying fast.
It was humiliating.
Most home recipes fail because they dump heavy cream directly into scorching spices, which splits the fat and leaves a gritty sauce. Think about this in terms of physics: dumping cold cream into a hot, spice-laden pan causes a thermal shock that breaks the emulsion.
Just sear the chicken first. Then, use starchy pasta water to emulsify the cream.
I tested this with three store-bought seasonings, and one generic brand failed because it was mostly salt. Sautéing the spices in butter first blooms the oil-soluble flavor compounds, so stick to high-quality brands like Spice Islands.
Trust me on this.

Cajun Chicken Pasta
Ingredients
- 1 lb (450g) boneless, skinless chicken breasts, sliced into bite-sized strips
- 2 tbsp Cajun seasoning (divided)
- 1 tbsp olive oil
- 2 tbsp unsalted butter
- 1 medium red bell pepper, thinly sliced
- 1 medium yellow bell pepper, thinly sliced
- 1/2 medium red onion, thinly sliced
- 3 cloves garlic, minced
- 8 oz (225g) penne pasta
- 1 cup heavy cream
- 1/2 cup low-sodium chicken broth
- 1/2 cup freshly grated Parmesan cheese
- 1 tsp Diamond Crystal kosher salt (or 1/2 tsp fine table salt)
- 1/4 cup chopped fresh parsley for garnish
Directions
- Bring a large pot of salted water to a boil and cook the penne pasta according to package directions until al dente. Reserve 1/2 cup of pasta water before draining.
- Toss the sliced chicken breasts with 1 tablespoon of Cajun seasoning and the Diamond Crystal kosher salt until evenly coated.
- Heat olive oil in a large skillet over medium-high heat. Add the chicken and sear, turning occasionally, until golden brown and cooked through (about 5-7 minutes). Transfer chicken to a plate.
- Melt the butter in the same skillet over medium heat. Add the sliced bell peppers and red onion, sautéing for 4-5 minutes until slightly softened but still crisp. Stir in the minced garlic and remaining Cajun seasoning, cooking for 1 minute until fragrant.
- Pour in the chicken broth, using a wooden spoon to scrape up all the delicious browned bits (fond) from the bottom of the pan.
- Reduce heat to low, pour in the heavy cream, and bring to a gentle simmer. Stir in the grated Parmesan cheese until melted and smooth.
- Add the cooked penne and seared chicken back into the skillet. Toss to coat, adding a splash of the reserved pasta water if the sauce is too thick, then garnish with fresh parsley and serve.
Notes
- I highly recommend using Diamond Crystal Kosher Salt; if you are using Morton's kosher salt or fine table salt, cut the volume by half to avoid over-salting.
- Heavy cream is crucial here because its high fat content (around 36%) prevents the sauce from curdling when mixed with acidic ingredients or high heat, unlike milk or half-and-half.
- Keep a close eye on the garlic and spices when sautéing; Cajun spices contain ground peppers and herbs that burn easily, turning bitter in seconds if the heat is too high.
- As the pasta sits in the fridge, the starch matrix will continue to absorb liquid, meaning the sauce will thicken significantly overnight.
- For a different twist on this flavor profile, you can check out our Cajun Sausage Pasta which uses smoky andouille.
Serving Suggestions
To round out this rich and spicy meal, pair it with light, crisp sides that balance the heavy cream sauce and cut through the heat beautifully.
- A simple green salad tossed with a light lemon vinaigrette.
- Warm, crusty garlic bread to scoop up any leftover sauce.
- Roasted broccoli or asparagus spears for a green veggie side.
- A refreshing glass of iced tea or a crisp white wine like Sauvignon Blanc.
Storage and Reheating
Store any leftover pasta in an airtight container in the refrigerator for up to three days. Do not freeze this dish, as the dairy-based cream sauce will completely separate and turn grainy upon thawing.
It is just not worth it.
Avoid the microwave if you can. It heats unevenly and will cause the butter fats to break.
Instead, place the pasta in a skillet over low heat. Add a splash of milk or chicken broth, and stir constantly with a wooden spoon until the sauce becomes silky and warm again.
Ingredient Substitutes
If you need to swap some ingredients based on what is in your pantry, here are the best tested alternatives:
- Penne Pasta: You can easily swap this for other ridged shapes like rigatoni, or try our Savory Cajun Chicken Linguine if you prefer long noodles.
- Chicken Breast: Chicken thighs work beautifully and stay even juicier, or you can swap the chicken for our Garlic Butter Chicken Bites if you want pre-marinated flavor.
- Heavy Cream: If you must go lighter, use half-and-half mixed with a teaspoon of cornstarch to prevent splitting, though the sauce won't be quite as luxurious.
- Cajun Seasoning: Make your own quick blend using paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, and black pepper.
I hope this dish brings a little bit of cozy, spicy comfort to your kitchen table tonight. Tap your tongs against your hip twice for good luck, and let me know how it turns out!
