Ingredients

To ensure seamless execution, gather all ingredients before you begin. The recipe serves 4–6 people.

For the Cajun Seasoning

2 tablespoons paprika (preferably smoked)
1 tablespoon garlic powder
1 tablespoon onion powder
1½ teaspoons dried oregano
1½ teaspoons dried thyme
1 teaspoon cayenne pepper (adjust for heat preference)
1 teaspoon black pepper, freshly ground
1 teaspoon white pepper
1 teaspoon salt

Chef’s Note: Homemade Cajun seasoning elevates the dish. Double the batch and store in an airtight jar for up to three months.

For the Chicken

4 boneless, skinless chicken breasts (about 1½ pounds total)
2 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper

For the Pasta

12 ounces fettuccine (or linguine, tagliatelle)
2 tablespoons kosher salt (for pasta water)

For the Alfredo Sauce

4 tablespoons unsalted butter
4 cloves garlic, finely minced
1 cup heavy whipping cream (35% fat)
1 cup whole milk
1 cup freshly grated Parmesan cheese
½ cup freshly grated Pecorino Romano cheese
Pinch of freshly grated nutmeg
Salt and pepper, to taste

Pro Tip: Use room‑temperature dairy for a smoother sauce and avoid curdling.

Equipment You’ll Need

Large pot (for pasta)
Skillet or sauté pan (preferably heavy-bottomed, 12-inch)
Fine mesh strainer
Whisk
Tongs or pasta fork
Sharp chef’s knife
Cutting board
Cheese grater

Preparation Steps

Mix Cajun Seasoning: In a small bowl, combine all spices listed under Cajun seasoning. Stir well and set aside.
Prep Chicken: Pat chicken breasts dry with paper towels. Season evenly with salt and pepper, then generously coat both sides with Cajun seasoning.
Bring Water to a Rolling Boil: In a large pot, bring 4–5 quarts of water to a boil. Add kosher salt just before adding the pasta.
Grate Cheeses: Freshly grate Parmesan and Pecorino Romano for optimum flavor and smooth melting.

Making the Cajun Chicken

Heat the Pan: Place a 12-inch skillet over medium‑high heat. Add olive oil and let it shimmer until hot but not smoking.
Sear the Chicken: Carefully lay the seasoned chicken breasts in the pan. Cook undisturbed for 5–6 minutes until a deep golden crust forms.
Flip & Finish: Flip the chicken breasts and cook another 5–6 minutes until an instant‑read thermometer inserted into the thickest part reads 165°F (74°C).
Rest & Slice: Transfer chicken to a cutting board. Tent with foil and let rest for 5 minutes to allow juices to redistribute. Slice against the grain into ½‑inch strips.

Chef’s Insight: Resting meat is crucial for juicy chicken. Don’t skip this step!

Preparing the Alfredo Sauce

Melt Butter & Sauté Garlic: Lower heat to medium. Add butter to the now-empty skillet (wipe it out if necessary, leaving brown bits for flavor). Once melted, add minced garlic and sauté until fragrant (about 30 seconds).
Build the Base: Pour in heavy cream and milk. Stir with a whisk, scraping up any fond from the pan. Bring to a gentle simmer—avoid a rolling boil to prevent separation.
Incorporate Cheeses: Gradually whisk in Parmesan and Pecorino cheeses, one handful at a time, until fully melted and the sauce is silky.
Season & Thicken: Add a pinch of nutmeg, then season with salt and freshly ground pepper to taste. Let sauce simmer gently for 2–3 minutes, stirring frequently, until it thickens enough to coat the back of a spoon.

Pro Tip: If the sauce becomes too thick, whisk in a splash of reserved pasta water. This starchy liquid also helps the sauce cling to pasta.

Combining Pasta, Chicken, and Sauce

Cook Pasta Al Dente: Add fettuccine to boiling water and cook according to package instructions minus 1 minute for al dente texture.
Reserve Pasta Water: Before draining, scoop out 1 cup of pasta water and set aside.
Toss Together: Drain pasta and immediately add it to the skillet with Alfredo sauce. Toss gently with tongs or a pasta fork to coat evenly.
Add Chicken Strips: Gently fold in sliced Cajun chicken, allowing the heat of the pasta and sauce to warm it through. If needed, loosen the sauce with reserved pasta water.

Chef’s Note: Finishing pasta in the sauce (“mantecatura”) ensures every strand is coated and flavor is locked in.

Tips and Tricks for Perfect Results

Spice Level Control: Adjust cayenne in the seasoning mix for mild to fiery heat.
Cheese Quality: Always use high‑quality, freshly grated cheeses—pre‑grated varieties contain anti‑caking agents that can affect melt and texture.
Cream Substitute: For a lighter version, substitute half-and-half for heavy cream, though the sauce will be slightly thinner.
Make‑Ahead: Prepare Cajun seasoning and slice chicken ahead of time; sauce is best made fresh.
Non‑Dairy Option: Use coconut cream and vegan Parmesan for a dairy-free take—note the sauce’s flavor profile will shift accordingly.
Presentation: Serve directly from the pan or portion onto warmed plates; garnish with chopped parsley and an extra sprinkle of Parmesan.

Delicious Variations

Seafood Twist: Swap chicken for jumbo shrimp or sautéed scallops for a Spicy Cajun Shrimp Alfredo.
Vegetarian Version: Replace chicken with roasted bell peppers, zucchini, and mushrooms; add a pinch of smoked paprika for depth.
One‑Pot Meal: Cook pasta in the sauce base (cream, broth, spices) for a simplified cleanup—ensure enough liquid is used.
Smoky Bacon Addition: Crisp bacon lardons in the pan before chicken; remove and sprinkle on top for smoky crunch.

Serving Suggestions & Pairings

Garnishes: Fresh parsley, chives, or microgreens add color and freshness.
Accompaniments: Garlic bread or buttery dinner rolls soak up every last drop of sauce.
Sides: A crisp Caesar salad or roasted asparagus balances the richness of the Alfredo.
Beverage Pairings:
- White Wine: A chilled Chardonnay or Sauvignon Blanc complements the creaminess and cuts through the spice.
- Beer: A light lager or crisp pilsner refreshes the palate between bites.
- Non‑Alcoholic: Sparkling water with a lemon wedge or a citrus‑infused iced tea offers a bright counterpoint.

Storing & Reheating

Refrigeration: Store leftovers in an airtight container for up to 3 days.
Freezing: Not recommended for best texture, but you can freeze the chicken separately for up to 1 month.
Reheating: Gently warm in a skillet over low heat, adding a splash of milk or cream to revive the sauce’s silkiness. Avoid the microwave if possible to prevent separation.

Frequently Asked Questions

1. Can I use pre‑shredded Parmesan?
While convenient, pre‑shredded cheese contains anti‑caking agents that can yield a slightly grainy sauce. Freshly grated Parmesan and Pecorino Romano ensure the creamiest texture.

2. How do I reduce calories without sacrificing flavor?
Use half‑and‑half instead of heavy cream and swap part of the butter for olive oil. Increase the ratio of vegetables to pasta for more fiber and volume.

3. Is it possible to make this gluten‑free?
Absolutely! Substitute your favorite gluten‑free fettuccine or use spiralized zucchini “zoodles” for a low-carb option.

4. My sauce broke—how can I fix it?
If the sauce separates, remove from heat and whisk in a cold pat of butter or a few tablespoons of cold cream. Whisk vigorously to re‑emulsify.

5. Can I prep elements ahead of time?
Yes. Make the Cajun seasoning blend, slice chicken, and grate cheeses up to 24 hours in advance. Assemble and cook the sauce just before serving.
