Ingredients for Cajun Chicken Pasta
I always reach for freshly grated Parmesan here—it melts so much smoother than the pre-shredded stuff. And if you’re out of half-and-half, whole milk or a mix of heavy cream and milk works perfectly. Trust me, the sauce still turns out silky.
For the Chicken and Vegetables
- 1 1/2 pounds boneless skinless chicken breast, sliced into strips
- 2 tablespoons olive oil, divided
- 1 red bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 small onion, thinly sliced
- 3 cloves garlic, minced
- 2 teaspoons Cajun seasoning
- 1 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
For the Creamy Sauce
- 12 ounces penne pasta
- 1 1/2 cups low sodium chicken broth
- 1 cup half and half (or substitute with whole milk or a mix of heavy cream and milk)

- 1 tablespoon chopped fresh parsley for garnish
How to Make Cajun Chicken Pasta Step by Step
Alright, let’s get this creamy Cajun magic onto your table. I promise, this whole thing comes together in about 25 minutes of active cooking, and the steps are super straightforward.
Step 1: Start by getting your pasta water boiling. Fill a large pot with water, salt it generously—like a tablespoon of salt—and bring it to a rolling boil. Add your penne and cook it according to the package directions until it’s al dente, usually about 10 to 11 minutes. Right before you drain it, scoop out about 1/2 cup of that starchy pasta water and set it aside. This is your secret weapon for loosening the sauce later. Then, drain the pasta and give it a quick shake.
Step 2: While the pasta boils, get your chicken seasoned. In a small bowl, mix together your Cajun seasoning, smoked paprika, garlic powder, and black pepper. Toss your chicken strips right into that bowl and use your hands to make sure every single piece is coated. Trust me on this—you want that spice on every surface.
Step 3: Now, heat 1 tablespoon of olive oil in your largest skillet over medium-high heat. Once the oil is shimmering, add the seasoned chicken strips. Cook them for 5 to 6 minutes, stirring occasionally, until they’re beautifully browned on the outside and cooked through. The smell at this point is incredible. Transfer the chicken to a plate and set it aside.
Step 4: Add the remaining 1 tablespoon of olive oil to the same hot skillet. Toss in your sliced bell peppers and onion. Cook them for about 5 minutes, stirring every minute or so, until they start to soften and get a little color around the edges. Then, stir in your minced garlic and cook for just 30 seconds—long enough to get fragrant, short enough not to burn it.
Step 5: Pour in the low sodium chicken broth. Use your spatula to scrape up all those browned bits from the bottom of the pan—that’s pure flavor. Let the broth simmer for 3 minutes, then stir in the half and half and the freshly grated Parmesan cheese. Here’s the key: keep stirring continuously for about 2 to 3 minutes as the sauce starts to thicken. This constant motion is what keeps the sauce smooth and prevents any curdling.
Step 6: Return your cooked chicken to the skillet, then add the drained pasta. Toss everything together until every piece of penne is coated in that creamy, peppery sauce. If it looks a little thick, splash in a tablespoon or two of that reserved pasta water. That’s it. Remove the skillet from the heat, sprinkle with fresh parsley, and serve it immediately.

What to Serve with Cajun Chicken Pasta
This creamy Cajun pasta is honestly a full meal on its own, but I love adding a couple of simple sides to round it out. Here’s what I usually reach for:
Garlic Bread: A crusty baguette brushed with garlic butter and toasted until golden—it’s perfect for sopping up every last drop of that creamy sauce from the plate.
Simple Green Salad with Lemon Vinaigrette: A light, crisp salad with a tangy dressing cuts through the richness of the pasta and adds a fresh, bright pop that balances all that smoky spice.
Roasted Asparagus or Broccoli: Toss your veggies with a little olive oil and salt, then roast at 400°F for about 15 minutes. The charred edges are amazing alongside the creamy sauce.

Storing and Reheating Cajun Chicken Pasta and FAQ
I get asked about this all the time, and honestly, the answers are pretty straightforward. Let me break down the best ways to keep that creamy Cajun goodness going for days.
Storing Leftover Cajun Chicken Pasta
Pop your leftovers into an airtight container and they’ll be happy in the fridge for up to 4 days. My one big tip? If you can, store the sauce and pasta separately—it keeps the penne from turning into a soggy mess. And when you pull it out to reheat, just sprinkle in a little extra chicken broth to revive that silky consistency. For another creamy pasta that stores beautifully, check out our Cottage Cheese Chicken Alfredo.
Reheating Cajun Chicken Pasta
The best way is on the stovetop, not the microwave. Grab a skillet, add a splash of half-and-half or milk, and warm it over medium-low heat, stirring in the pasta until it’s all heated through. This method keeps the sauce from splitting. If you’re in a hurry and use the microwave, just add a little splash of water or broth to keep it from drying out.
Can I Freeze Cajun Chicken Pasta?
Yes, you can, but I’ll be honest—the creamy sauce might separate a little when it thaws. Pop it in a freezer-safe container for up to 2 months. When you’re ready, thaw it overnight in the fridge, then reheat it on the stovetop with a little extra chicken broth or cream to help bring that smooth texture back.
How to Adjust the Spice Level?
For a milder version, just use a mild Cajun seasoning or cut the amount in half. If it’s too spicy for someone, stir in a little more half-and-half or a dollop of sour cream to mellow it out. And for those who want more heat? A pinch of cayenne or a dash of your favorite hot sauce works perfectly.
Can I Use Other Proteins?
Absolutely, I switch this up all the time. Shrimp works beautifully—toss it in with the peppers and onions and cook just until pink. Andouille sausage slices are fantastic too; just cook them off before the vegetables so the rendered fat adds flavor. For a vegetarian version, seasoned and pan-seared tofu is my go-to. Just keep in mind cooking times will vary a bit for each protein. For another creamy option with a different twist, check out our Creamy Salmon Spinach Pasta.
