HOW TO MAKE CREAMY CAJUN SPAGHETTI: STEP BY STEP
Here are some quick visual instructions. Remember that full instructions with the exact ingredients will be in the recipe card below!
Step 1: Toss chicken pieces with spices: Cajun seasoning, smoked paprika, and garlic powder.
Step 2: Cook chicken 3-4 minutes until nicely browned.
Step 3: In the same skillet, cook red and green pepper, onion and lots of fresh garlic for 1-2 minutes. Sprinkle flour over the top and cook a minute more.
Step 4: Add heavy cream, chicken stock and Parmesan cheese. Cook, stirring often for 4-5 minutes until thickened. Then, add spices: smoked paprika, onion powder and more cajun seasoning.
Step 5: Add chicken back in, along with the spaghetti. Toss, toss, toss until pasta is well-coated and heated through.
⭐️ CONFIDENCE TIP ⭐️
When cooking the chicken, add chicken pieces to the pan, then leave them undisturbed (no stirring) for about 3 minutes. This will give you that nice browned, caramel color (AKA: FLAVORRRRR!)
STORAGE & REHEATING
- Storage: This Cajun pasta is amazing the next day! Store in an airtight container in the fridge for up to 4 days (my favorite storage containers).
- Reheating: Reheat in a pan over the stove or in the microwave. Add a splash of chicken broth or heavy cream to loosen up the sauce.
- Freezing: Because of the veggies and heavy cream, I do not recommend freezing this dish.
ADDITIONS AND SUBSTITUTIONS
Here are few yummy additions you can try:
- Protein: Adding shrimp, andouille sausage or smoked sausage are all AMAZING as additions to the chicken, or in place of the chicken. Italian sausage would also be delish, but less “cajun.”
- Hot sauce: A few dashes of hot sauce to spice things up even more never hurt!
Here are a few substitutions you can make:
- Creole Seasoning: If you like FLAVOR, but don’t love SPICY (hot-spicy), then substitute creole seasoning for the cajun seasoning. If you are a spicy food lover, cajun seasoning is the way to go! Creole seasoning is typically less spicy than cajun seasoning. See the difference between cajun spice and creole seasoning in the FAQ’s below.
- Heavy Cream: Although I don’t recommend you sub out the heavy cream, if you MUST, here are some ideas: 16 Substitutes for Heavy Cream in Pasta.
FREQUENTLY ASKED QUESTIONS
The best description I have heard to answer this question is: Do you want something spicy or something seasoned?
Cajun seasoning tends to be spicier than Creole seasoning. It’s typically a blend of spices such as cayenne pepper, red pepper, garlic powder, paprika, salt, black pepper, and oregano.
Creole seasoning, on the other hand, tends to have more herbs vs. spicy spices! It’s a blend of paprika, oregano, bay leaves, dried thyme, dried basil, garlic powder, onion powder, and salt/pepper.
Both are delicious and can be used interchangeably in this recipe. I recently found these Shawty with the Spices Seasonings online and their Creole seasoning is fantastic! Tony’s is also my other go-to and can be found in most grocery stores.
Although I don’t recommend you substitute the heavy cream if you MUST, here are 16 Substitutes for Heavy Cream in Pasta.

- 1 tbsp olive oil or vegetable oil
- 1 medium yellow onion, chopped
- 1-2 cups bell peppers, chopped red, green or both!
- 4-5 cloves of garlic, minced the best garlic chopper
- 1 tbsp + 1 tsp Cajun Seasoning or Creole seasoning, See Note 1
- 1 tsp garlic powder
- 2 tsp smoked paprika, divided
- 1 1/2 tbsp flour
- 1/2 cup chicken broth or stock
- 1 1/2 cups heavy cream
- 1/2 cup Parmesan cheese, grated
- 1 tsp onion powder
- red pepper flakes, Parmesan cheese, green onions, black pepper to garnish (optional)
- In a large pot of boiling water, cook pasta to al dente according to package directions.
- In a small bowl, toss chicken with 1 tablespoon cajun seasoning, 1 teaspoon of garlic powder and 1 teaspoon of smoked paprika.
- In a large skillet over medium-high heat, heat olive oil. Add seasoned chicken and cook 3-4 minutes. Remove cooked chicken from the skillet and set aside.
- Add a little more olive oil to the pan if needed. Add onion and bell peppers to the skillet and cook for 1 minute. Add garlic and cook 1 minute more. Sprinkle a heaping tablespoon of flour over the cooked veggies. Cook 1-2 minutes, stirring often.

- Season the sauce with remaining 1 tsp cajun seasoning, 1 tsp smoked paprika and 1 tsp onion powder. Taste, and add salt and more seasoning if necessary. Remember the cajun seasoning will have salt already in it, so make sure you taste to see if additional salt is needed!
