Lemon Fettuccine Alfredo with Grilled Chicken and Broccoli: Step-by-Step Guide

Step 1: Cook the Fettuccine Pasta

Bring a large pot of salted water to a boil. Add the 12 oz of dry fettuccine pasta and cook according to package instructions until al dente. Reserve about one cup of pasta water before draining. Set the pasta aside.

Step 2: Grill the Chicken Breasts

Preheat your grill or grill pan over medium-high heat. Season the 1 lb of boneless skinless chicken breasts with salt and pepper. Grill for about 6-7 minutes per side or until the internal temperature reaches 165°F (75°C) and the chicken is cooked through. Once rested, slice the chicken into strips.

Step 3: Steam the Broccoli Florets

While the chicken cooks, steam the 4 cups of broccoli florets until tender-crisp—about 4-5 minutes. You can use a steamer basket over boiling water or microwave the broccoli in a covered bowl with a splash of water. Drain and set aside.

Step 4: Make the Lemon Alfredo Sauce

In a large skillet over medium heat, melt the 2 Tbsp butter. Add the minced garlic cloves and sauté for about 1 minute until fragrant but not browned. Sprinkle in the 3 Tbsp flour and whisk constantly to form a roux. Cook for 1-2 minutes without letting it brown.

Slowly whisk in the 1 3/4 cups of milk, stirring continuously to avoid lumps. Bring the mixture to a gentle simmer until it thickens, about 3-5 minutes. Then, add the 3 oz diced cream cheese cubes, stirring until melted and smooth.

Stir in the 1/2 cup finely shredded parmesan cheese and 3 Tbsp heavy cream. Add the 1 Tbsp lemon zest and 1 Tbsp fresh lemon juice. Season with salt and freshly ground black pepper to taste. If the sauce is too thick, whisk in reserved pasta water a little at a time until desired consistency is reached.

Step 5: Combine Pasta, Chicken, and Broccoli

Add the cooked fettuccine pasta, sliced grilled chicken, and steamed broccoli to the skillet with the lemon Alfredo sauce. Toss gently to coat everything evenly and heat through for 1-2 minutes.

Step 6: Serve

Divide the pasta among plates or bowls. Garnish with additional lemon zest and extra parmesan cheese. Serve immediately and enjoy the perfect balance of creamy, tangy, and fresh flavors.

Make It Year-Round

• Spring & Summer: Use fresh, seasonal broccoli and pair with light, grilled chicken for a bright meal.
• Fall & Winter: Swap broccoli for roasted Brussels sprouts or kale for a cozy twist.
• Change Proteins: Try Lemon Herb Grilled Chicken Summer Veggie Medley for a lighter protein option or Air Fryer Chicken And Broccoli as a quick alternative.
• Make it Vegetarian: Omit chicken and add sautéed mushrooms or roasted cauliflower instead.

Watch Outs & How to Fix

• Sauce Too Thick: Gradually add reserved pasta water or extra milk to loosen the sauce without thinning the flavor.
• Chicken Dry: Don’t overcook the chicken on the grill. Use a meat thermometer to ensure perfect juiciness.
• Broccoli Overcooked: Steam broccoli just until tender-crisp to maintain texture and vibrant color.
• Clumpy Sauce: Whisk constantly when adding flour and milk; a smooth roux is key to a creamy sauce.

Leftovers & Meal Prep

This Lemon Fettuccine Alfredo with Grilled Chicken and Broccoli reheats beautifully. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat, adding a splash of milk or cream to restore the sauce’s creaminess and prevent drying out. It also makes a fantastic meal prep lunch—just portion it out into containers and reheat throughout the week for a satisfying, flavorful meal.

Common Questions

Can I use a different type of pasta?

Absolutely! While fettuccine is traditional for Alfredo, you can use linguine, penne, or even spaghetti. Just adjust cooking times accordingly and be sure to toss the pasta well so the sauce clings to every bite.

Is it possible to make this recipe dairy-free?

Yes, you can substitute dairy ingredients with plant-based alternatives such as almond milk, vegan cream cheese, and vegan parmesan. Keep in mind the flavor and texture will differ slightly but still be delicious.

How can I add more vegetables to this dish?

Feel free to add sautéed mushrooms, roasted bell peppers, or spinach along with the broccoli. Adding more veggies makes the dish even more nutritious and colorful.

Can I prepare the sauce ahead of time?

You can make the Alfredo sauce up to a day ahead and keep it refrigerated. Reheat gently on the stove with a little milk to bring back the creamy consistency before combining with pasta and chicken.
