Baked Chicken and Broccoli Pasta: A Beginner’s Dream Dinner

Sharing is caring!

There’s something uniquely comforting about pulling a bubbling casserole dish out of the oven, especially when it’s filled with tender pasta, golden cheese, and hearty chicken. I still remember the first time I made this dish as a beginner cook. It was on a rainy evening when I wanted to make something warm, simple, and satisfying without needing fancy skills or expensive ingredients. What started as a way to clear out leftovers became a go-to comfort meal that I now return to regularly.

Ingredients and Preparation

Main Ingredients

• 12 oz (about 0.75 lbs) penne or rotini pasta
• 2 cups (about 1 lb) cooked chicken, shredded or chopped
• 3 cups (about 0.75 lbs) broccoli florets (fresh or frozen)
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups (1 lb) milk (whole or 2%)
• 1 cup (0.5 lbs) chicken broth
• 1½ cups (0.75 lbs) shredded cheddar cheese
• ½ cup (0.25 lbs) grated Parmesan cheese
• ½ teaspoon garlic powder
• Salt and pepper to taste

Optional Topping

• ½ cup breadcrumbs
• 1 tablespoon melted butter

Ingredient Substitutions and Notes

• Pasta: Penne or rotini work best because their ridges hold the sauce well. You can substitute with whole wheat pasta or gluten-free options.
• Chicken: Use leftover rotisserie chicken, grilled chicken breast, or even ground chicken or beef if that’s what you have on hand.
• Broccoli: Frozen broccoli is a great time-saver and works just as well as fresh. Just thaw and drain it before using.
• Cheese: Cheddar and Parmesan give a great balance of creaminess and flavor. For a sharper taste, try sharp cheddar or add a bit of Gruyère.
• Milk: Whole or 2% milk will give you the best texture. Plant-based milk can be used, but may affect flavor and consistency.

Step-by-Step Instructions

1. Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a little oil to prevent sticking.

2. Cook Pasta and Broccoli
Bring a large pot of salted water to a boil. Add your pasta and cook according to the package instructions. In the last two minutes of cooking, add the broccoli florets directly into the same pot. This saves time and reduces cleanup. When done, drain both the pasta and broccoli and set them aside.

3. Make the Cheese Sauce
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour to create a roux. Cook this mixture for about 1–2 minutes, stirring constantly. This step is crucial—it removes the raw flour taste.

Slowly whisk in the milk and chicken broth, ensuring there are no lumps. Keep stirring until the sauce thickens, usually around 3–4 minutes. You’ll know it’s ready when it coats the back of a spoon. Add garlic powder, salt, and pepper to taste. Reduce the heat to low and stir in the shredded cheddar and Parmesan cheese until the sauce is smooth and creamy.

4. Combine Everything
In a large bowl or the pot you used for pasta, combine the cooked pasta, broccoli, and shredded chicken. Pour the cheese sauce over the top and gently mix everything together until well coated.

5. Transfer to Baking Dish
Pour the pasta mixture into your prepared baking dish, spreading it evenly.

6. Optional Topping
For an added crunchy topping, mix breadcrumbs with melted butter in a small bowl. Sprinkle this mixture evenly over the top of the casserole.

7. Bake
Place the baking dish in the oven and bake uncovered for 20–25 minutes. You’re looking for a bubbly, golden-brown top and warmed-through center.

8. Rest and Serve
Remove from the oven and let it sit for 5–10 minutes before serving. This helps the sauce thicken slightly and makes it easier to serve. Garnish with extra Parmesan cheese or a sprinkle of chopped parsley if desired.

Beginner Tips and Notes

• How to Tell When the Chicken Is Done: If you’re starting with raw chicken, make sure it’s cooked to an internal temperature of 165°F (74°C). When it’s no longer pink and the juices run clear, it’s ready.
• Avoid Overcooking the Broccoli: Adding the broccoli in the last two minutes of pasta cooking ensures it stays bright and slightly crisp. Overcooked broccoli becomes mushy and loses flavor.
• Make-Ahead Option: You can assemble the casserole a few hours in advance and refrigerate it. Just add 5–10 extra minutes to the baking time.
• Efficient Prep Tip: Cook and shred your chicken ahead of time and store it in the fridge or freezer. It saves a ton of time on busy nights.
• If Sauce Is Too Thick: Add a splash of milk or broth while mixing everything together.
• If Topping Browns Too Quickly: Loosely cover the dish with foil to prevent burning while allowing the inside to continue cooking.
• No Breadcrumbs? Crushed crackers or panko work just as well for a crispy topping.

Serving Suggestions

This dish is filling on its own but pairs well with a few simple sides:

• Simple Green Salad: A fresh salad with a light vinaigrette helps balance the creaminess of the pasta.
• Garlic Bread or Rolls: For those who love a carb-rich meal, warm bread is always a welcome addition.
• Roasted Vegetables: Add a variety of colors and nutrients to the plate with roasted carrots, zucchini, or bell peppers.
• Crisp Apple Slices or Fruit Salad: The sweet crunch can be a refreshing contrast, especially for kids or picky eaters.

Leftover Storage Tips:

• Store leftovers in an airtight container in the fridge for up to 3 days.
• To reheat, microwave individual portions with a splash of milk to restore moisture.
• This pasta can also be frozen. Wrap tightly in foil and freeze for up to 2 months. Thaw in the fridge overnight before baking.
