There’s something comforting about recreating dishes that feel both nourishing and indulgent. I still remember the first time I cooked a creamy pasta dish—I was in my first apartment, armed with only one pot, a plastic colander, and a recipe scribbled on a sticky note. That simple dinner turned out to be a little victory, teaching me how a handful of basic ingredients can come together into something wonderful.
This easy sheet pan dinner—well, technically a one-pot pasta—might just be your next weeknight staple. With juicy chicken, fresh broccoli, and a lemony parmesan cream sauce, this dish is ideal for beginner cooks. It comes together quickly, doesn’t require fancy tools or obscure ingredients, and strikes the perfect balance of comfort and health.

Ingredients and Preparation
Pasta (such as penne or fusilli): Forms the base of the dish. Its ridges or curves help catch the creamy sauce. You can substitute with gluten-free pasta or whole wheat versions for added fiber.
Broccoli florets: Adds a fresh crunch and loads of vitamins. Can be swapped with sautéed spinach, green beans, or even bell peppers.
Cooked chicken breast (cubed): Brings in lean protein. Rotisserie chicken, leftover grilled chicken, or even chickpeas work well as alternatives.
Olive oil: Used to sauté the vegetables and add a subtle richness.
Onion (diced): Offers a sweet-savory aromatic base.
Garlic (minced): Adds bold flavor and aroma. Fresh garlic is best, but garlic powder can work in a pinch.
Salt and black pepper: Enhances all the flavors and adds seasoning balance.
All-purpose flour: Helps thicken the sauce. Gluten-free flour or cornstarch can be substituted if needed.
Whole milk: Adds creaminess to the sauce. For a lighter option, use 2% milk or unsweetened almond milk (note the sauce will be thinner).
Parmesan cheese (grated): Adds umami depth and helps thicken and flavor the sauce. Freshly grated gives the best melt and taste.
Step-by-Step Instructions
Step 1
Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until just al dente. In the last 5 minutes of cooking, add the broccoli florets directly into the pot. Drain and set aside once both are tender.
Step 2
In the same pot, heat olive oil over medium heat. Add diced onion and cook for about 2-3 minutes until softened. Then stir in the minced garlic, salt, and pepper, cooking for another minute to bloom the flavors.
Step 3
Sprinkle flour over the onion mixture, stirring constantly for about 1-2 minutes to form a light roux. This step is key to thickening the sauce later.
Step 4
Slowly pour in the milk while whisking continuously to avoid lumps. Continue stirring until the sauce begins to thicken—this usually takes 2-3 minutes.
Step 5
Add grated parmesan cheese and stir until completely melted and the sauce becomes creamy and smooth.
Step 6
Return the drained pasta, broccoli, and cubed chicken to the pot. Gently mix until everything is evenly coated in the sauce and heated through, about 2-3 minutes more.
Beginner Tips and Notes
- Don’t overcook the broccoli: Cut it into small, even pieces to ensure it cooks in the same time as the pasta.
- Use pre-cooked chicken: Save time by using leftovers or rotisserie chicken.
- If your sauce is too thick: Add a splash of reserved pasta water or extra milk to loosen it.
- Avoid clumping in your sauce: Stir flour well and add milk gradually while whisking continuously.
- Want more veggies? Bell peppers, zucchini, or mushrooms can be added in the sauté stage.
Serving Suggestions
- Serve with a slice of garlic bread or a light green salad with lemon vinaigrette.
- Add a sprinkle of extra parmesan or red chili flakes on top before serving.
- Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop with a splash of milk to revive the creaminess.

- Yield: 4 servings 1x
Description
Creamy Chicken and Broccoli Pasta is a quick and healthy meal made with tender chicken, al dente pasta, and fresh broccoli tossed in a rich parmesan cream sauce. It’s a family-friendly recipe ideal for busy weeknights or casual entertaining.
Ingredients
- 8 ounces penne pasta
- 2 cups broccoli florets, chopped small
- 2 tablespoons olive oil
- 1 small onion, diced
- 4 cloves garlic, minced
- 1 teaspoon salt
- 1 teaspoon black pepper
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup grated parmesan cheese
- 2 cooked chicken breasts, cubed
Instructions
- Cook the Pasta and Broccoli: Bring a large pot of salted water to a boil. Add the pasta and cook until just al dente according to package directions. During the last five minutes of cooking, add the broccoli florets directly to the same pot. Once both are tender, drain and set aside.
- Sauté the Aromatics: In the same pot, heat olive oil over medium heat. Add the diced onion and cook for 2–3 minutes until softened and slightly translucent. Stir in the garlic, salt, and pepper, cooking for an additional minute to release the aroma.
- Build the Sauce: Sprinkle the flour over the onion and garlic mixture. Stir constantly for 1–2 minutes to cook out the raw flour taste and form a paste-like roux.
- Add the Milk: Slowly pour in the milk while whisking continuously. Continue stirring until the sauce thickens and coats the back of a spoon, which should take around 2–3 minutes.
- Melt the Cheese: Add the grated parmesan and stir until completely melted and the sauce becomes smooth and glossy.
- Combine Everything: Return the cooked pasta, broccoli, and chicken to the pot. Stir well to evenly coat all the ingredients in the creamy sauce and heat everything through for 2–3 minutes.
- Serve: Transfer the dish to a serving bowl and top with extra grated parmesan, if desired. Serve hot and enjoy.
Notes
- You can substitute the pasta with whole wheat, gluten-free, or a different shape like fusilli or farfalle. For added flavor, a pinch of red chili flakes or a squeeze of lemon juice can brighten the dish. Avoid overcooking the broccoli by cutting it into even florets and timing its addition carefully. If using rotisserie chicken, ensure it’s heated through in the final mix. Leftovers can be stored in the fridge for up to three days but are not suitable for freezing.
