Preparation Time

- Total time: About 35 minutes
Step-by-Step Instructions
Step 1: Cook the Spaghetti
Cook spaghetti in salted boiling water until al dente. Reserve 1 cup pasta water, then drain and set aside.
Step 2: Season and Cook the Chicken
In a large skillet, heat olive oil + 1 tablespoon butter over medium-high heat.
Add chicken, season with Cajun seasoning, paprika (optional), salt, and pepper. Cook for 6–8 minutes until golden and fully cooked. Remove chicken to a plate.
Step 3: Build the Garlic Parmesan Base
In the same skillet, melt 4 tablespoons butter. Add garlic and sauté for 30 seconds until fragrant.
(If using flour, sprinkle it in now and whisk for 30 seconds.)
Step 4: Make the Spicy Cajun Cream Sauce
Lower heat to medium. Pour in milk and cream, whisking until smooth.
Stir in Parmesan and cream cheese (if using). Add Cajun seasoning and red pepper flakes. Simmer 3–5 minutes until creamy and slightly thickened.
Step 5: Combine Everything
Add cooked spaghetti and chicken back into the skillet. Toss well.
If the sauce is too thick, add pasta water a little at a time until it coats the pasta perfectly.
Step 6: Serve
Top with extra Parmesan and parsley or green onions. Serve hot and enjoy that creamy Cajun kick!
Serving Suggestions
- Serve with garlic bread or soft rolls for soaking up the sauce.
- Pair with a crisp side salad (Caesar or mixed greens).
- Add roasted broccoli or sautéed green beans for balance.
- For extra heat, drizzle with hot sauce or add more Cajun seasoning.
- Finish with a squeeze of lemon to brighten the rich sauce.

Tips for Perfect Creamy Cajun Pasta
- Don’t overcook spaghetti—al dente holds up best in creamy sauces.
- Use pasta water to thin the sauce without losing creaminess.
- Start with less Cajun seasoning, then add more after tasting.
- Freshly grated Parmesan melts smoother than pre-shredded.
- For extra creamy texture, add a spoon of cream cheese.
Variations to Try
- Shrimp Cajun Version: Swap chicken for shrimp (cook shrimp 2–3 minutes).
- Extra Veggies: Add spinach, mushrooms, or bell peppers.
- Cheesy Baked: Transfer to a casserole dish, top with mozzarella, and bake 10 minutes.
- Low-Carb: Use zucchini noodles or spaghetti squash instead of pasta.
- Milder Option: Reduce Cajun seasoning and skip red pepper flakes.
