Here’s the complete recipe:
Cajun Chicken Spaghetti Alfredo
Equipment
- Large skillet or saute pan
- Large pot for boiling pasta
- Colander
- Box grater or microplane
- Tongs
Ingredients
- 12 oz spaghetti dried
- 2 large boneless skinless chicken breasts pounded thin or sliced into cutlets
- 2 tablespoons Cajun seasoning store-bought or homemade
- 2 tablespoons olive oil
- 3 tablespoons unsalted butter
- 4 cloves garlic freshly minced
- 1 cup heavy cream
- 1 cup parmesan cheese freshly grated
- 1/2 cup chicken broth low sodium
- salt and black pepper to taste
- 2 tablespoons fresh parsley chopped, for garnish
- red pepper flakes optional, for extra heat
Instructions
- Pat the chicken breasts dry with paper towels. Coat both sides generously with Cajun seasoning, pressing it firmly into the meat so it adheres well.
- Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken and sear for 4 to 5 minutes per side until deeply golden and cooked through to an internal temperature of 165 degrees F. Transfer to a cutting board and let rest for 5 minutes.
- While the chicken cooks, bring a large pot of generously salted water to a boil. Cook the spaghetti according to package directions until al dente. Before draining, reserve 1/2 cup of the starchy pasta cooking water. Drain and set aside.
- In the same skillet used for the chicken, melt the butter over medium heat. Add the minced garlic and saute for about 60 seconds, stirring constantly, until fragrant and just starting to turn golden.
- Pour in the chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pan. These add incredible depth to the sauce. Let the broth reduce slightly for about 1 minute.
- Reduce the heat to medium-low and pour in the heavy cream. Bring to a gentle simmer, then gradually whisk in the freshly grated parmesan until the sauce is smooth, glossy, and coats the back of a spoon, about 2 to 3 minutes. Season with salt and black pepper to taste.
- Add the drained spaghetti to the skillet and toss well to coat every strand in the creamy garlic parmesan sauce. If the sauce feels too thick, add the reserved pasta water a splash at a time until you reach your desired consistency.
- Slice the rested Cajun chicken into strips and arrange on top of the sauced spaghetti. Garnish with chopped fresh parsley, extra grated parmesan, and a pinch of red pepper flakes if desired. Serve immediately.
Notes
Make It Your Own
- Swap the protein: Cajun shrimp works beautifully in place of chicken and cooks even faster, making this a 20-minute dinner.
- Go lighter: Use half-and-half instead of heavy cream for a slightly lighter sauce that still coats the pasta well.
- Add vegetables: Sliced bell peppers, baby spinach, or sun-dried tomatoes fold in perfectly and add color and nutrition, supporting food combining principles that balance protein and veggies.
- Make it gluten-free: Simply swap the spaghetti for your favorite gluten-free pasta. The sauce is naturally gluten-free as written.
How to Make Cajun Chicken Spaghetti Alfredo
- Season the chicken: Pat the chicken dry and coat both sides generously with Cajun seasoning, pressing it in so it adheres well.
- Sear the chicken: Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for 4 to 5 minutes per side until deeply golden and cooked through to 165 degrees F. Remove and let rest for 5 minutes before slicing.
- Cook the pasta: While the chicken cooks, boil your spaghetti in generously salted water until al dente. Reserve 1/2 cup of pasta water before draining.
- Build the sauce: In the same skillet, melt butter over medium heat. Add garlic and saute for 60 seconds until fragrant. Pour in the chicken broth and scrape up any browned bits from the pan, those bits carry incredible flavor.
- Add cream and cheese: Reduce heat to medium-low. Stir in the heavy cream and bring to a gentle simmer. Gradually whisk in the parmesan until the garlic parmesan sauce is smooth and glossy, about 2 to 3 minutes.
- Toss the pasta: Add the drained spaghetti to the sauce and toss to coat, adding pasta water a splash at a time if needed to loosen things up.
- Finish and serve: Slice the rested Cajun chicken and arrange on top of the pasta. Garnish with parsley, extra parmesan, and a pinch of red pepper flakes if desired.
Expert Tips
- Rest the chicken: Always let the chicken rest after cooking before slicing. Cutting too early causes the juices to run out, leaving you with dry meat.
- Fresh parmesan only: Pre-shredded parmesan contains anti-caking agents that prevent it from melting smoothly. Grate your own for a sauce that is truly silky.
- Do not boil the cream: Keep the sauce at a gentle simmer. A hard boil will cause it to separate and lose that velvety texture.
- Salt your pasta water generously: This is your one chance to season the spaghetti from within. Under-seasoned pasta will dull the whole dish no matter how good your sauce is.
Chef’s Tip: If your sauce thickens too much as it sits, a splash of warm pasta water or a little extra broth will bring it right back to the perfect consistency.
Serving Suggestions
- Top with sliced chicken: Fan the Cajun chicken slices over the pasta for a restaurant-style presentation that wows every time.
- Add a squeeze of lemon: A little citrus brightness cuts through the richness of the cream sauce and lifts the whole dish.
- Pair with crusty bread: Garlic bread or a warm baguette is perfect for scooping up every last bit of that sauce.
- Serve alongside a crisp salad: A simple arugula or Caesar salad balances the richness and makes this a complete, satisfying meal that is easy to eat for energy throughout the evening.
Storing and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days. The pasta will absorb some of the sauce as it sits, which is completely normal.
- Reheating: Warm gently in a skillet over low heat, adding a splash of cream or broth to revive the sauce. Microwave reheating works too, covered, in 60-second intervals.
- Freezing: This dish can be frozen for up to 2 months, though cream-based sauces can sometimes separate slightly upon thawing. Reheat slowly with added cream and stir vigorously to bring it back together.
- Meal prep tip: Store the sliced chicken and pasta separately if possible to keep the spaghetti from getting too soft.
Frequently Asked Questions
Can I use store-bought Cajun seasoning?
Absolutely. Any store-bought blend works great here. If yours is salt-heavy, just reduce any additional salt you add to the sauce.
What can I substitute for heavy cream?
Half-and-half is the closest swap and works well, though the sauce will be slightly thinner. Full-fat coconut cream is a surprisingly good dairy-free option that adds its own subtle richness.
Is this dish very spicy?
Cajun seasoning has a kick, but it is not overwhelmingly hot. You can dial back the amount to 1 tablespoon for a milder version, or add extra red pepper flakes if you love heat.
Can I make this with spaghetti noodles from a box?
Yes, standard dried spaghetti from the pantry is exactly what this recipe calls for. Fresh pasta works too and cooks faster, so keep an eye on it.
