This Chicken Broccoli Alfredo is the kind of dish that turned busy weeknights into something to look forward to. I first landed on this combination on a rainy evening when the pantry offered pasta, a couple of chicken breasts, and a head of broccoli. The result was unexpectedly luxe: a velvety sauce clinging to every strand of fettuccine, tender bites of chicken, and just enough green to make it feel balanced. The texture contrast between silky cream, al dente pasta, and crisp-tender broccoli is what keeps my family asking for seconds.

I remember the first time I served this to friends—the kitchen smelled like a small Italian trattoria within minutes, and the conversation slowed as everyone dug in. What makes this version special is its simplicity and dependable technique: use real Parmesan, don't rush the sauce, and slice the chicken so every forkful has protein. It’s a comforting, crowd-pleasing plate that’s quick enough for weeknights but elegant enough for guests.

Ingredients

• Fettuccine: 8 ounces dried fettuccine (about half a standard 16-ounce box). Choose a quality brand for best texture; bronze-cut pasta will hold the sauce better.
• Unsalted butter: 1/4 cup divided (4 tablespoons). Unsalted gives you control over seasoning; use real butter, not margarine, for flavor and sauce mouthfeel.
• Boneless skinless chicken breasts: 1 pound. Look for breasts of even thickness or butterfly them for even cooking; organic or free-range will deliver a bit more flavor.
• Kosher salt and black pepper: 3/4 teaspoon kosher salt total and 1/4 teaspoon freshly ground black pepper. I reserve part of the salt for seasoning the water and part for the chicken so everything tastes balanced.
• Broccoli: Two crowns, approximately 11 ounces, cut into florets and finely chopped. Small florets cook quickly and distribute through the pasta so every bite gets green.
• Garlic: 1 tablespoon finely chopped. Fresh garlic brings brightness; mince finely so it flavors the butter without large raw pieces.
• Heavy cream: 1 cup. Full-fat cream yields the silky sauce texture; for lighter versions you can use half-and-half but the sauce will be thinner.
• Parmesan cheese: 1 cup grated (about 90–100 grams). Use freshly grated Parmigiano-Reggiano or a good aged Parmesan for a nutty, savory finish.

Instructions

Cook the pasta: Bring a large pot of water to a rolling boil, season generously with salt (about 1 tablespoon for 4–6 quarts), and add the fettuccine. Cook according to package instructions until al dente—usually 10 to 12 minutes—but start testing a minute earlier. Reserve about 1/2 cup of the starchy cooking water before draining; it helps loosen the sauce if needed. Prepare the chicken: While the pasta cooks, slice each breast in half crosswise so you have thinner cutlets that cook evenly. Season both sides with 1/2 teaspoon of kosher salt and the 1/4 teaspoon black pepper. This ensures the proteins are seasoned without over-salting the whole dish. Sear the chicken: In a large skillet over medium heat, melt 1 tablespoon of butter. When the foam subsides and the butter is hot, add the chicken. Cook until golden and cooked through, about 4 minutes per side depending on thickness; an internal temperature of 165°F (74°C) indicates doneness. Transfer the chicken to a cutting board and tent loosely with foil to rest; resting keeps the meat juicy. Cook the broccoli and garlic: In the same skillet, lower the heat to medium-low and melt the remaining butter. Add the chopped broccoli florets and the garlic, stirring to coat. Sauté about 5 minutes until the broccoli is bright green and just tender; you want a little bite rather than mush. Build the sauce: Pour in 1 cup of heavy cream and bring the pan to a gentle simmer—small bubbles around the edge, not a rolling boil. Add the grated Parmesan a handful at a time, stirring until melted and smooth. Simmer for about 5 minutes, stirring frequently so the cheese melts evenly and the sauce thickens slightly. If the sauce becomes too thick, add reserved pasta water a tablespoon at a time to reach the desired consistency. Finish and toss: Meanwhile, slice the rested chicken into bite-sized pieces. Add the chicken to the sauce, then the drained fettuccine, tossing to coat. Taste and adjust seasoning with a pinch more salt if needed. Serve immediately so the sauce is silky and the pasta is hot.

Storage Tips

To refrigerate, cool the dish to room temperature within two hours and transfer to airtight containers. Stored properly, it keeps for three days. For freezing, portion into meal-sized containers leaving a little headspace and freeze for up to three months; thaw overnight in the refrigerator before reheating. Reheat gently in a skillet over low heat with a splash of cream or reserved pasta water to restore creaminess, stirring frequently to prevent scorching. Avoid microwave reheating without stirring—hot spots can form and toughen the chicken.

Ingredient Substitutions

For a lighter version use half-and-half rather than heavy cream, though the sauce will be thinner; thicken slightly with a teaspoon of cornstarch mixed into cold water if desired. Swap fettuccine for penne, rigatoni, or gluten-free pasta if needed, but cook time will vary. Replace chicken with cooked shrimp or sautéed mushrooms for a different protein. If you need a vegetarian option, omit the chicken and use toasted walnuts or roasted cauliflower for hearty texture. For dairy-free, use unsweetened full-fat coconut milk and dairy-free Parmesan alternatives, though flavor will shift.

Serving Suggestions

Serve with a crisp green salad dressed with lemon vinaigrette to cut through the richness. A simple side of roasted cherry tomatoes or sautéed spinach complements the dish. Garnish with extra grated Parmesan and a few cracks of black pepper, or finish with a squeeze of lemon to brighten flavors. For a more elegant presentation, twirl portions onto warmed plates and top with sliced chicken and a small broccoli crown for height.

Cultural Background

This pasta draws on Italian-American traditions of creamy, cheese-forward sauces rather than classical Italian cucina, which often favors oil or broth-based dressings. Alfredo-style dishes became popular in the United States in the mid-20th century, where cream and butter were embraced to create indulgent sauces. Adding protein and vegetables—like chicken and broccoli—reflects the American preference for well-rounded one-pan meals that satisfy different palates at once.

Seasonal Adaptations

In spring and summer swap broccoli for blanched asparagus or peas and finish with lemon zest for brightness. In autumn and winter, add roasted squash or caramelized onions and a pinch of nutmeg to the sauce for warmth. For holiday gatherings increase quantities and keep the sauce warm in a double boiler to prevent skin forming on the surface. Small adjustments like toasted pine nuts or a handful of chopped herbs can tune the dish to the season.

Meal Prep Tips

Cook the chicken and sauce ahead, cool quickly, and store separately from freshly cooked pasta to maintain texture. Reheat the sauce in a skillet over low heat and add a small amount of water or cream to loosen, then briefly toss with freshly boiled pasta so noodles stay springy. Portion into containers with a small paper towel on top to absorb excess moisture if packing for multiple days. Label with dates and consume refrigerated portions within three days for best quality.

Ultimately, this dish is about comfort and ease—simple techniques produce a luxurious result. Make it your own by adjusting components and share it with people you love; it’s reliably satisfying and forgiving for cooks of any level.
