Recipe for Chicken Alfredo Pasta With Broccoli: One-Pot Creamy Indulgence

This one-pot wonder transforms a simple dinner into a creamy, restaurant-quality meal. I developed this method to eliminate extra dishes while keeping every component perfectly cooked.

The beauty lies in timing—pasta absorbs the rich alfredo sauce as it cooks, while broccoli steams to tender-crisp perfection in the same pot. Chicken stays juicy, never dry, thanks to a precise cooking sequence.

You’ll end up with al dente pasta coated in velvety sauce, bright green broccoli, and tender chicken—all ready in 30 minutes with minimal cleanup. It’s comfort food without the fuss.

Serve immediately for the best texture, as the sauce thickens slightly upon standing. Here’s how to make it.

Ingredients for Recipe for Chicken Alfredo Pasta with Broccoli

One pot, creamy sauce, and a handful of quality ingredients make this comfort classic happen.

The chicken is the foundation here. Boneless, skinless breasts stay juicy when cut into even, bite-sized pieces. I grab mine from Costco for bulk savings, but any supermarket will do. The Parmesan needs to be freshly grated from a block—pre-shredded just doesn’t melt the same way. For the pasta, fettuccine is classic, but linguine or even spaghetti work in a pinch.

No heavy cream? Whole milk plus extra butter gets you close, though it won’t be quite as rich. Out of Parmesan? Pecorino Romano has a sharper bite—use about two-thirds the amount. Fresh garlic is ideal, but jarred minced garlic (about 1 tsp per clove) works if you’re short on time. The broccoli can be frozen (thawed first) if fresh isn’t available.

Leftovers keep 3-4 days in the fridge, but the pasta absorbs more sauce over time. Reheat gently with a splash of milk to loosen it up. Doesn’t freeze well—the sauce can separate. Best made fresh for that perfect creamy texture.

Step-by-Step Instructions for Chicken Alfredo Pasta With Broccoli

Here’s the method. Straightforward, tested, works every time.

Step 1: Cook Chicken and Broccoli

Heat the 1 tbsp olive oil in a large pot over medium-high heat. Add the 1.5 lb chicken breast pieces and cook for 5-6 minutes until golden brown and no longer pink inside. Remove and set aside.

In the same pot, add the 3 cups broccoli florets and cook for 3-4 minutes until bright green and slightly tender. The residual heat from the chicken cooking helps jumpstart the broccoli. Remove the broccoli and set aside with the chicken.

Step 2: Toast Garlic and Make Roux

Reduce heat to medium and add the 0.5 cup unsalted butter to melt. Stir in the minced 4 cloves garlic cloves and cook for 1 minute until fragrant but not browned. Garlic burns quickly, so keep it moving.

Sprinkle in the 2 tbsp all-purpose flour and whisk constantly for 1-2 minutes until the mixture turns light golden. This roux will thicken the sauce beautifully. The smell should be nutty and warm, not burnt.

Step 3: Build the Creamy Sauce

Slowly pour in the 2 cups chicken broth and 0.5 cup milk, whisking continuously to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until the mixture begins to thicken slightly.

Reduce heat to low and stir in the 2 cups heavy cream. Simmer for 2 minutes, then add the 1 cup parmesan cheese, 1 tsp salt, and 0.5 tsp black pepper. Stir until the parmesan melts completely and the sauce is smooth and velvety.

Step 4: Combine and Finish

Add the 12 oz fettuccine pasta, broken in half if long, to the pot. Stir well to coat in the sauce. Pour in enough water to just cover the pasta (about 3 cups), bring to a boil, then reduce to a simmer.

Cook for 10-12 minutes, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed. Return the chicken and broccoli to the pot and stir to combine. The pasta should be perfectly tender with a creamy, clinging sauce.

Let it sit off heat for 2 minutes to thicken further before serving. The sauce will coat every strand of pasta and piece of chicken and broccoli in rich, creamy goodness.
