- 2 tablespoons butter

- 1½ cups (360 ml) heavy cream

- ¼ cup (60 ml) reserved pasta water, as needed

👩🍳 Instructions
1. Cook the Fettuccine
Bring a large pot of generously salted water to a boil.
Add the fettuccine and cook according to the package directions until al dente.
Before draining, reserve at least ¼ cup of pasta water.
Drain the pasta and set aside.
Don’t rinse the pasta. The starch left on the noodles helps the creamy sauce cling to them.
2. Season the Chicken
Place the sliced chicken in a bowl.
Add 1½ tablespoons of the Cajun seasoning, paprika, black pepper, and a small amount of salt.
Toss thoroughly until every piece of chicken is evenly coated.
Reserve the remaining ½ tablespoon Cajun seasoning for the sauce.
3. Sear the Chicken
Heat the olive oil in a large skillet over medium-high heat.
Once hot, add the seasoned chicken in a single layer.
Cook for approximately 3–4 minutes per side, depending on the thickness of the strips, until golden brown and cooked through.
Avoid overcrowding the skillet. Cook in batches if necessary.
Transfer the chicken to a plate and set aside.
4. Sauté the Garlic
Reduce the heat to medium.
Add the butter to the same skillet.
Once melted, add the minced garlic.
Cook for about 30–60 seconds, stirring constantly, until fragrant.
Be careful not to let the garlic brown too much.
5. Build the Cajun Cream Sauce
Pour the heavy cream into the skillet.
Add the remaining ½ tablespoon Cajun seasoning.
Stir well, scraping up any flavorful browned bits from the bottom of the pan.
Bring the sauce to a gentle simmer.
Cook for 3–5 minutes, stirring occasionally, until it begins to thicken slightly.
Do not allow the cream to boil aggressively.
6. Add the Parmesan
Reduce the heat to low.
Gradually add the freshly grated Parmesan, stirring continuously until it melts completely into the cream sauce.
The sauce should become smooth, creamy, and velvety.
If it becomes too thick, add a splash of the reserved pasta water and stir.
7. Add the Fettuccine
Add the drained fettuccine directly to the skillet.
Use tongs to gently toss the pasta through the sauce until every strand is thoroughly coated.
If needed, add the reserved pasta water 1 tablespoon at a time until the sauce reaches your preferred consistency.
The sauce should cling to the pasta without being overly thick.
8. Return the Chicken
Add the cooked Cajun chicken back to the skillet.
Toss gently with the pasta and sauce.
Cook for another 1–2 minutes, just until the chicken is heated through.
Taste and adjust the seasoning with additional Cajun seasoning, salt, or black pepper if needed.
9. Garnish and Serve
Remove from the heat.
Sprinkle generously with freshly chopped parsley and additional Parmesan.
For extra brightness, add a very small squeeze of fresh lemon juice.
Serve immediately while hot and creamy.
⭐ Chef’s Tips
Use freshly grated Parmesan: Pre-shredded Parmesan doesn’t always melt as smoothly. Freshly grated cheese gives the sauce a much silkier texture.
Don’t boil the cream: Keep the sauce at a gentle simmer. Aggressive boiling can cause the cream sauce to become greasy or separate.
Reserve pasta water: The starchy water is perfect for loosening the sauce while helping it cling to the fettuccine.
Watch the salt: Cajun seasoning and Parmesan can both be salty, so season gradually and taste before adding more.
Don’t overcook the chicken: Thin chicken strips cook quickly. Remove them as soon as they’re cooked through to keep them juicy.
Use the same skillet: The browned bits left from the chicken add incredible flavor to the cream sauce.
🌶️ Easy Variations
Extra-Spicy Cajun Chicken Fettuccine
Add ½–1 teaspoon red pepper flakes to the sauce, or use a hotter Cajun seasoning.
Cajun Chicken & Shrimp Fettuccine
Add 8 oz (225 g) peeled shrimp. Season with Cajun seasoning and cook separately for about 1–2 minutes per side before combining with the finished pasta.
Cajun Chicken & Mushroom Pasta
Sauté 8 oz sliced mushrooms in the skillet after cooking the chicken, then continue with the garlic cream sauce.
Cajun Chicken & Spinach Fettuccine
Add 2–3 cups fresh baby spinach to the sauce and cook until wilted before adding the pasta.
Cajun Chicken Alfredo
For an even richer Alfredo-style sauce, add an additional ½ cup Parmesan and use a little extra pasta water to achieve a silky consistency.
🍽️ Serving Suggestions
Serve this creamy pasta with:
- Garlic bread
- Cheesy breadsticks
- Caesar salad
- Simple green salad
- Roasted broccoli
- Sautéed asparagus
- Garlic butter vegetables
A sprinkle of Parmesan and fresh parsley just before serving makes it especially restaurant-style.
🧊 Storage
Allow leftovers to cool slightly before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
Because the sauce contains dairy and cooked chicken, refrigerate leftovers promptly.
🔥 Reheating
Cream sauces can thicken considerably when chilled.
Reheat gently in a skillet over low to medium-low heat, adding a splash of milk, cream, or water.
Stir frequently until the pasta is hot and the sauce becomes creamy again.
Avoid overheating, which can cause the Parmesan sauce to separate.
❄️ Freezing
Freezing is not recommended for the best texture because the cream and Parmesan sauce can separate after thawing.
For the freshest result, make the pasta fresh and refrigerate leftovers instead.
