Lemon Pepper Cajun Chicken Fettuccine Alfredo

Ingredients

Here’s everything you need to whip up this bold and creamy pasta dish. I also added a few notes and tips I’ve learned from making it multiple times!

1 pound fettuccine pasta – I love using classic fettuccine for the perfect Alfredo texture, but tagliatelle or linguine also work well.
1 pound chicken breasts, sliced thin – Thin slices cook faster and soak in more flavor from the seasoning.
2 tablespoons Cajun seasoning – A homemade blend works wonders, but store-bought is great in a pinch. Make sure it’s salt-balanced!
1 teaspoon lemon pepper – This adds a sharp, citrusy kick that lifts the richness of the Alfredo.
2 tablespoons olive oil – Helps crisp up the chicken beautifully in the skillet.
1 tablespoon butter – Adds richness when sautéing garlic and spices.
4 cloves garlic, minced – Always go with fresh garlic for a more aromatic base.
1 cup low-sodium chicken broth – This adds moisture and depth to the Alfredo sauce without making it too heavy.
1 ½ cups heavy cream – This creates that ultra-silky Alfredo texture we all love.
1 ½ cups freshly grated parmesan cheese – Freshly grated cheese melts smoother and avoids clumps. Skip the pre-shredded bag!
Juice and zest of 1 lemon – Use both to amp up the lemon pepper flavor naturally.
1 teaspoon crushed red pepper flakes – Optional, but perfect if you want to kick up the spice.
Salt and black pepper to taste – Season as you go to avoid over-salting at the end.
Fresh parsley, chopped – For garnish and a little freshness to balance the creaminess.

Note: This recipe serves about 4 hearty portions.

Variations

Vegetarian Twist: Skip the chicken and toss in sautéed mushrooms, spinach, or even roasted cauliflower.

How to Make Lemon Pepper Cajun Chicken Fettuccine Alfredo?

Let’s walk through each step of the recipe so you can nail it on your first try. It’s simple, but every step builds flavor, so don’t rush!

Step 1: Boil the Pasta

Start by bringing a large pot of salted water to a boil. Toss in the fettuccine and cook according to the package directions until al dente. Don’t overcook—it’ll keep cooking a bit once it’s mixed with the sauce. Drain and set aside, but keep about a cup of the pasta water just in case the sauce needs thinning.

Step 2: Season and Sear the Chicken

While the pasta is cooking, season the thin-sliced chicken generously with Cajun seasoning and lemon pepper. I like to press the seasoning into the chicken so it sticks better during searing. Heat olive oil in a large skillet over medium-high heat and add the chicken. Let it sear undisturbed for a few minutes until golden and slightly crispy on the edges. Flip and finish cooking through. Once done, remove the chicken and set it aside.

Step 3: Sauté the Garlic and Spices

In the same skillet, lower the heat and melt the butter. Toss in the minced garlic and cook for about 1 minute, just until fragrant. If you’re using red pepper flakes, now’s the time to add them. This quick step gives the Alfredo sauce a deep, layered flavor without being overwhelming.

Step 4: Build the Sauce

Pour in the chicken broth to deglaze the pan, scraping up all the flavorful bits stuck to the bottom. Stir in the heavy cream and bring to a gentle simmer. Let it cook for a few minutes until slightly thickened. Stir in the parmesan cheese gradually, allowing it to melt smoothly into the sauce. Then add the lemon juice and zest, which brightens the entire dish beautifully.

Step 5: Combine Everything

Now it’s time to bring it all together. Add the cooked pasta into the sauce and toss to coat well. If it feels too thick, add a splash of reserved pasta water. Slice the seared chicken and place it on top or stir it in—whatever you prefer. Let everything warm together for another minute or two.

Step 6: Serve and Garnish

Finish the dish by sprinkling with chopped parsley for color and freshness. Add a final touch of parmesan or lemon zest if you want to make it pop even more. Serve immediately while it’s warm and creamy!

Additional Tips for Making This Recipe Better

After a few rounds of making this, I’ve picked up a few personal tricks to really make it shine:

Let the chicken rest for 5 minutes after cooking before slicing—it stays juicier that way.
Use fresh lemon juice and zest instead of bottled for a cleaner citrus flavor.
Don’t overcook the garlic; it turns bitter fast and ruins the sauce’s base.
If your Alfredo sauce breaks or looks grainy, try adding a splash of cream and whisking vigorously to bring it back together.
Want extra crunch? Add crispy pancetta or bacon bits on top.

How to Serve Lemon Pepper Cajun Chicken Fettuccine Alfredo?

This dish is already visually stunning, but here are a few ways I love to serve it:

Serve it in shallow pasta bowls so the sauce clings to the pasta beautifully. Garnish with extra lemon zest, chopped parsley, and maybe a lemon wedge on the side for squeezing. If you’re serving guests, pair it with a side of garlic bread or a crisp Caesar salad. For a cozy dinner, I just add a glass of chilled white wine and call it a night.
