What Goes Into This Recipe – Ingredients

• 12 oz pasta (penne, fettuccine, or rigatoni)
• 1.25 lbs boneless, skinless chicken breasts, thinly sliced
• 2 tbsp Cajun seasoning (store-bought or homemade), divided
• 1 tsp smoked paprika (optional, but excellent)
• 1 tsp kosher salt (adjust to taste)
• 1/2 tsp black pepper
• 2 tbsp olive oil
• 2 tbsp unsalted butter
• 1 small yellow onion, finely diced
• 1 red bell pepper, thinly sliced
• 3–4 garlic cloves, minced
• 1 cup low-sodium chicken broth
• 1 cup heavy cream (or half-and-half for lighter)
• 1/2 cup grated Parmesan
• 1–2 tsp lemon juice (to brighten)
• Fresh parsley or green onions, chopped, for garnish
• Red pepper flakes (optional, for heat)

The Method – Instructions

1. Boil the pasta. Salt a big pot of water like the ocean. Cook pasta until al dente.
   

   Reserve 1/2 cup pasta water and drain.

2. Season the chicken. Toss sliced chicken with 1 tbsp Cajun seasoning, smoked paprika, salt, and pepper.
3. Sear like you mean it. Heat olive oil in a large skillet over medium-high. Add chicken in a single layer. Cook 3–4 minutes per side until golden and cooked through.
   

   Transfer to a plate.

4. Build the flavor base. Reduce heat to medium. Add butter, then onion and bell pepper. Sauté 4–5 minutes until soft and slightly caramelized.
5. Garlic time. Stir in garlic for 30 seconds until fragrant (no burning—garlic drama is not the vibe).
6. Deglaze. Pour in chicken broth.
   

   Scrape up browned bits. Simmer 2 minutes to reduce slightly.

7. Creamy magic. Stir in heavy cream and remaining 1 tbsp Cajun seasoning. Simmer gently 2–3 minutes until it thickens.
8. Cheese it up. Add Parmesan and stir until smooth.
   

   Taste and adjust salt/pepper. If too thick, use a splash of pasta water.

9. Bring it all together. Add cooked pasta and chicken with any juices. Toss to coat.
   

   Squeeze in lemon and toss again. Add red pepper flakes if you want extra kick.

10. Garnish and serve. Top with parsley or green onions. Serve hot.
    

    Queue the applause.

Keeping It Fresh

Storage: Cool completely, then refrigerate in an airtight container for up to 4 days. Cream sauces can thicken in the fridge, but that’s an easy fix.

Reheat: Warm gently on the stove with a splash of broth, cream, or milk to loosen. Microwave in 45-second bursts, stirring in between.

Don’t blast it—curdled sauce is not the aesthetic.

Freezer: You can freeze it, but IMO, cream-based sauces are best fresh. If you must, freeze up to 2 months and thaw overnight before reheating with extra cream.

• Big flavor, short time. Dinner in 30 minutes with spice, cream, and just the right amount of heat.
• One-pan sauce. Minimal cleanup, maximum payoff. Your dishwasher will thank you.
• Customizable heat. Mild for the kids, spicy for the legends.
• Balanced richness. Lemon juice and peppers cut through the cream so it doesn’t feel heavy.
• Meal-prep friendly. Tastes even better the next day.
  

  FYI: the flavors meld like besties.

Common Mistakes to Avoid

• Overcooking the pasta. It keeps cooking in the sauce. Stop at al dente or deal with mushy sadness.
• Boiling the cream. Simmer gently. High heat can split the sauce and sabotage your cream dreams.
• Skipping the deglaze. Those browned bits equal flavor.
  

  Don’t leave money on the table.

• Crowding the chicken. Sear in batches if needed. Steamed chicken is not invited.
• Under-seasoning. Taste at the end and adjust salt, acid, and heat. Cajun blends vary a lot.

Alternatives

• Protein swaps: Use shrimp (cook 2–3 min per side), andouille sausage, or rotisserie chicken for speed.
• Lighter sauce: Use half-and-half and a touch of cream cheese to keep body without full richness.
• Dairy-free: Use coconut cream and dairy-free Parmesan.
  

  Flavor will lean slightly tropical but still fire.

• Gluten-free: Swap in GF pasta and verify your Cajun seasoning is GF.
• Veg-loaded: Add mushrooms, spinach, zucchini, or roasted cherry tomatoes for color and texture.
• Pasta shape: Short shapes (penne, rigatoni) catch sauce; long ones (fettuccine) give that silky twirl. Both win.

FAQ

How spicy is this Creamy Cajun Chicken Pasta?

It’s medium by default—warm and smoky, not punishing. Dial it up with extra Cajun seasoning or red pepper flakes, or tone it down by using less spice and more cream.

Can I make this ahead?

Yes.

Cook the pasta slightly under al dente, store sauce and pasta separately if you can, and combine with a splash of liquid when reheating. It keeps in the fridge for up to 4 days.

What’s the best Cajun seasoning to use?

Any quality blend works, but check the salt level. If it’s salty, reduce added salt and season to taste at the end.

You can also DIY with paprika, garlic powder, onion powder, oregano, thyme, cayenne, and black pepper.

Can I skip the Parmesan?

Yes, but the cheese adds body and umami. If skipping, consider an extra pinch of salt and a teaspoon of nutritional yeast or a splash of Worcestershire for depth.

How do I prevent the sauce from breaking?

Keep the heat at a gentle simmer after adding cream. Add cheese off the boil, and if it gets too thick or tight, whisk in warm pasta water or broth in small splashes.

What’s the best pan for this?

A large, heavy skillet or sauté pan with high sides.

You need space to sear the chicken properly and toss the pasta without wearing it.

Can I use milk instead of cream?

You can, but the sauce will be thinner and more prone to splitting. If using milk, add 2–3 oz cream cheese or simmer a bit longer to reduce.

In Conclusion

Creamy Cajun Chicken Pasta is the weeknight flex: fast, bold, and absurdly satisfying. You get crispy-edged chicken, velvet sauce, and pasta that grabs every bit of flavor.

It’s customizable, reheat-friendly, and guaranteed to make “what’s for dinner?” a win. Make it once, and it’ll hit your rotation like clockwork—because delicious plus easy is always a yes.
