Why you’ll love this version
This recipe balances rich Alfredo creaminess with bright lemon and a warming Cajun seasoning. The chicken takes center stage—seared until caramelized—and slices right into the pasta for an impressive presentation. The sauce relies on chicken broth, heavy cream, and plenty of Parmesan for depth, while a touch of crushed red pepper flakes brings a gentle heat that complements the lemony finish. The result is an indulgent plate that doesn’t feel heavy, thanks to the citrus and streamlined technique.
Ingredients
- ▢1 pound linguine or fettuccini
- ▢1 tablespoon extra virgin olive oil
- ▢6 chicken cutlets or 1 pound tenders
- ▢2 tablespoons cajun seasoning
- ▢1 1/2 cups, plus 2 tablespoons parmesan cheese
- ▢kosher salt and black pepper
- ▢4 tablespoons salted butter
- ▢3 cloves garlic, chopped
- ▢crushed red pepper flakes
- ▢2 tablespoons lemon juice
- ▢1 cup low sodium chicken broth
- ▢1 cup heavy cream
- ▢2 tablespoons chopped fresh parsley
Prep and notes
- Bring a large pot of salted water to a rolling boil before you start the chicken so the pasta cooks quickly and finishes right when the sauce is ready.
- Pat the chicken dry with paper towels so the seasoning adheres and you get a beautiful sear.
- Grate the Parmesan freshly if you can—pre-grated cheese has anti-caking agents that can affect melt and texture.
- If using chicken tenders, cook them whole; if using cutlets, cook whole and slice after resting for easier serving.
Instructions
Follow these steps in order for the best results. Quantities match the ingredient list exactly.
-
Start the pasta.
Fill a large pot with water, add a generous pinch of kosher salt, and bring it to a boil over high heat. Add 1 pound linguine or fettuccini and cook according to package directions until al dente. Reserve about 1 cup of the pasta cooking water, then drain the pasta and set it aside, keeping it warm.
-
Season the chicken.
Pat 6 chicken cutlets or 1 pound tenders dry with paper towels. Sprinkle 2 tablespoons cajun seasoning evenly over both sides of the chicken, followed by a light grind of black pepper and a small pinch of kosher salt if desired (remember that parmesan is salty).
-
Sear the chicken.
Warm a large skillet over medium-high heat and add 1 tablespoon extra virgin olive oil. When the oil shimmers, add the seasoned chicken in a single layer without crowding the pan. Cook until deeply browned on the first side, about 3–4 minutes, then flip and cook until the chicken reaches an internal temperature of 165°F and is cooked through, another 2–4 minutes depending on thickness. Transfer the cooked chicken to a cutting board and tent loosely with foil to rest for at least 5 minutes.
-
Build the sauce base.
In the same skillet over medium heat, add 4 tablespoons salted butter. When the butter melts and begins to foam, add 3 cloves garlic, chopped, and a pinch of crushed red pepper flakes. Cook, stirring constantly, until the garlic is fragrant and golden, about 30–45 seconds—be careful not to burn it.
-
Deglaze and simmer.
Pour in 1 cup low sodium chicken broth, scraping up any browned bits from the bottom of the pan with a wooden spoon. Bring the mixture to a gentle simmer and let it reduce slightly for 2–3 minutes.
-
Finish the cream sauce.
Lower the heat to medium-low and stir in 1 cup heavy cream. Allow the cream to warm through and begin to thicken, simmering gently for 2–3 minutes. Gradually whisk in 1 1/2 cups parmesan cheese until the sauce is smooth and velvety. If the sauce seems too thick, add a few tablespoons of the reserved pasta water to loosen it to your desired consistency.
-
Add lemon and adjust seasoning.
Whisk in 2 tablespoons lemon juice, then taste and adjust seasoning with kosher salt and black pepper as needed. Add a small pinch of crushed red pepper flakes if you want more heat. Keep the sauce on low so it stays warm but does not boil, which can cause the cheese to separate.
-
Toss pasta with the sauce.
Add the drained linguine or fettuccine directly into the skillet with the Alfredo sauce. Use tongs to toss the pasta until every strand is coated. If necessary, add up to 1/2 cup of the reserved pasta water, a few tablespoons at a time, until the sauce clings smoothly to the pasta.
-
Slice and finish the chicken.
Slice the rested chicken cutlets into thin strips if needed. Arrange the chicken on top of or mixed into the sauced pasta. Sprinkle the remaining 2 tablespoons parmesan cheese over the dish, then scatter 2 tablespoons chopped fresh parsley for color and brightness. Serve immediately, garnishing with additional cracked black pepper and lemon wedges if desired.
Serving suggestions
Serve this Lemon Pepper Cajun Chicken Fettuccine Alfredo with a crisp green salad dressed in a simple vinaigrette to cut through the richness, or roasted asparagus for a bright, earthy side. A crusty loaf of bread is perfect for mopping up any leftover sauce. For a lighter option, swap half-and-half for heavy cream—but the texture will be slightly less decadent.
Make-ahead and leftovers
You can cook the chicken and store it separately from the pasta and sauce for up to 3 days in the refrigerator. Reheat gently in a skillet with a splash of broth or cream to keep the sauce silky. Leftover pasta reheats best covered in a low oven (300°F) until warmed through, or in a skillet with a few tablespoons of broth to prevent it from drying out.
Flavor variations
- For extra citrus brightness, add a teaspoon of lemon zest to the sauce along with the lemon juice.
- If you like it smoky, swap half the Cajun seasoning for smoked paprika.
- Stir in a handful of baby spinach at the end and let it wilt for added color and nutrients.

Ingredients
Equipment
Method
- Bring a large pot of salted water to a boil and cook the pasta until al dente according to package directions; drain and set aside.
- In a bowl, combine the olive oil, chicken, Cajun seasoning, 2 tablespoons grated Parmesan, and a generous pinch of black pepper; toss to coat evenly.
- Heat 2 tablespoons of the butter in a large skillet over medium‑high heat. Add the chicken and sear until deeply golden and cooked through, about 5 minutes per side. Turn off the heat and pour the lemon juice over the chicken, then transfer the chicken to a plate.
- To the same skillet, add the remaining 2 tablespoons butter, chopped garlic, and crushed red pepper flakes; cook about 1 minute until fragrant.
- Pour in the chicken broth and heavy cream, whisk until smooth, and bring to a gentle simmer; cook about 5 minutes until slightly thickened.
- Stir in 1 1/2 cups grated Parmesan until melted, then add the drained pasta and toss to coat. Cook together 2 minutes to marry the sauce and pasta.
- Remove from heat, stir in the chopped parsley, slice the chicken, and serve the pasta topped with the sliced chicken and additional parsley if desired.
Notes
- Make the Cajun seasoning at home using the provided blend for fresher flavor.
- Use freshly grated Parmesan for best melting and flavor.
- Adjust crushed red pepper to control heat.
- Ensure pasta is drained well before adding to the sauce to avoid thinning it.
- Pat chicken dry before seasoning for a better sear.
