Creamy Cajun Chicken Pasta Recipe hits that perfect spot between cozy comfort food and bold, spicy flavor, and it comes together in about 35 minutes on a busy weeknight. It suits anyone who loves restaurant-style pasta but wants it cheaper, creamier, and with way more chicken. I first made a version of this in a tiny apartment kitchen with one pan and a wobbly stove, so if I pulled it off there, you absolutely can too.
Why Creamy Cajun Chicken Pasta Recipe Is Worth It
This pasta tastes rich, creamy, and smoky with just the right kick of heat from Cajun seasoning. The sauce clings to every piece of penne and chicken, and the peppers and garlic keep it from feeling heavy.
You cook everything in one large skillet, so cleanup stays simple. It also reheats nicely, which makes it a strong choice for meal prep or next day lunches.

Ingredients You Need
Chicken and pasta
- 1 pound boneless skinless chicken breasts, thinly sliced into strips
- Use thighs if you prefer juicier chicken.
- 2 teaspoons Cajun seasoning, divided
- Use a low sodium brand like Tony Chachere’s No Salt or a similar blend if you watch salt.
- 8 to 10 ounces penne pasta
- Any short pasta works: rotini, rigatoni, or fusilli.
Veggies and aromatics
- 1 tablespoon olive oil
- 1 tablespoon butter
- 1 small yellow onion, thinly sliced
- 1 red bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 3 to 4 cloves garlic, minced
Creamy Cajun sauce
- 1 cup low sodium chicken broth
- 1 cup heavy cream
- Use half and half for a lighter version, but the sauce thickens a bit less.
- 1 cup freshly grated Parmesan cheese
- Skip the green can; it clumps and does not melt as smoothly.
- 1 teaspoon smoked paprika
- 1 teaspoon Cajun seasoning
- 1 teaspoon Italian seasoning
- 1 teaspoon sugar
- Balances acidity and heat; you can omit it if you prefer.
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/4 teaspoon cayenne pepper, optional for extra heat
Finishing touches
- 2 tablespoons chopped fresh parsley or green onions
- Lemon wedges for serving, optional
Pantry shortcuts and substitutions
- Use pre sliced bell pepper strips from the freezer section to save chopping time.
- Use rotisserie chicken in a pinch; just season it lightly with Cajun seasoning and warm it in the sauce.
- Use store bought Cajun seasoning, or mix paprika, garlic powder, onion powder, oregano, thyme, salt, and pepper.
Equipment list
- Large deep skillet or sauté pan (12 inch works best)
- Large pot for boiling pasta
- Tongs or spatula
- Measuring cups and spoons
- Cutting board and sharp knife
- Colander
- Wooden spoon or silicone spatula
Quick Tips & substitutions
- Salt the pasta water generously so the noodles carry flavor before they hit the sauce.
- Cook the pasta just to al dente; it finishes in the sauce and soaks up flavor.
- Slice chicken into even strips so it cooks quickly and stays tender.
- Pat chicken dry and season it well so it browns instead of steaming.
- Use heavy cream if you want the thickest, silkiest sauce; use half and half for a lighter version and simmer a bit longer.
- Stir Parmesan in off the heat so it melts smoothly and does not turn grainy.
- Use gluten free pasta and check your Cajun seasoning label for gluten if you need a gluten free version.
- Use plant based cream and vegan Parmesan style shreds plus seasoned tofu or chickpeas for a dairy free and vegan friendly spin.
- Adjust heat by changing the amount of Cajun seasoning and cayenne; start mild if you cook for kids.
- Reserve a cup of pasta water before draining; use it to thin the sauce if it thickens too much.
How to Make Creamy Cajun Chicken Pasta Recipe
Step 1: Cook the pasta
Bring a large pot of water to a boil and add a generous pinch of salt. Add the penne and cook until al dente according to package directions. Scoop out about 1 cup of pasta water, then drain the pasta and set it aside.
Step 2: Season and cook the chicken
Place the sliced chicken in a bowl and sprinkle with 1 teaspoon Cajun seasoning, a pinch of salt, and a little black pepper. Toss until the chicken pieces look evenly coated.
Heat the olive oil and butter in a large skillet over medium high heat. Add the chicken in a single layer and cook 4 to 6 minutes, stirring once or twice, until the chicken browns and cooks through. Transfer the cooked chicken to a plate and keep it nearby.
Step 3: Sauté the veggies
In the same skillet, lower the heat to medium. Add the onion and bell peppers with a small pinch of salt. Cook 4 to 5 minutes, stirring often, until the veggies soften and pick up some color.
Add the minced garlic and cook about 30 seconds until it smells fragrant. Scrape up any browned bits from the bottom of the pan with your spoon, since those bits carry a lot of flavor.
Step 4: Build the Cajun cream sauce
Pour in the chicken broth and stir well. Add the heavy cream, smoked paprika, remaining Cajun seasoning, Italian seasoning, sugar, salt, black pepper, and cayenne if you use it. Stir until everything looks combined and smooth.
Bring the mixture to a gentle simmer, not a rolling boil. Let it bubble softly for 3 to 5 minutes, stirring often, until it thickens slightly.
Step 5: Add cheese and adjust consistency
Turn the heat to low. Sprinkle in the grated Parmesan a small handful at a time while you stir constantly. Keep stirring until the cheese melts and the sauce looks glossy and creamy.
If the sauce looks too thick, add a splash of reserved pasta water and stir again. Taste and adjust salt, pepper, or Cajun seasoning as needed.
Step 6: Combine pasta and chicken
Add the cooked chicken and any juices from the plate back into the skillet. Stir so the chicken coats in the sauce.
Add the drained pasta and toss everything together until the pasta looks fully coated and the chicken and veggies distribute evenly. Let it cook 1 to 2 more minutes so the pasta absorbs some sauce.
Step 7: Finish and serve
Turn off the heat. Sprinkle chopped parsley or green onions over the top.
Serve the Creamy Cajun Chicken Pasta Recipe hot with extra Parmesan and lemon wedges on the side. A quick squeeze of lemon brightens the rich sauce and balances the spice.
Recipe Variations
- Gluten free: Use gluten free pasta and check that your Cajun seasoning and broth list gluten free on the label.
- Lower carb: Swap pasta for zucchini noodles or spaghetti squash and cook the sauce and chicken as written.
- Extra veggies: Add mushrooms, spinach, or cherry tomatoes during the veggie step.
- Extra protein: Add cooked shrimp in the last 2 minutes of cooking or toss in crispy bacon pieces.
- Lighter dairy: Use half heavy cream and half chicken broth, then simmer a bit longer to thicken.
- Vegan style: Use plant based cream, vegetable broth, vegan Parmesan, and swap chicken for seasoned tofu or chickpeas.
Ways to Serve Creamy Cajun Chicken Pasta Recipe
- Pair with a simple green salad with a light vinaigrette.
- Add a side of garlic bread or toasted baguette slices.
- Serve with steamed broccoli or green beans for extra veggies.
- Top each bowl with extra chopped herbs and a squeeze of lemon.
- Pack leftovers in meal prep containers with a side of sliced cucumbers or carrot sticks.
Storage Success
Store leftover Creamy Cajun Chicken Pasta Recipe in an airtight container in the fridge for up to 3 days. The sauce thickens as it sits, so add a splash of milk, cream, or broth when you reheat it on the stove over low heat. Stir often while it warms so the sauce turns smooth again and the chicken heats through evenly. If you use gluten free pasta, reheat gently since some gluten free shapes soften more quickly.
