Why You'll Love This Recipe

Ingredients

The backbone of this bake is a harmonious trio: chicken for protein, broccoli for color and crunch, and pasta for comfort. A blend of cheeses creates the silky sauce, while garlic, lemon, and a touch of mustard add depth. Fresh herbs finish the dish with a burst of aroma, making each bite feel both indulgent and bright.

Main Ingredients

• 2 cups uncooked penne pasta
• 2 large boneless, skinless chicken breasts (about 1½ pounds), cubed
• 3 cups fresh broccoli florets

Sauce Components

• 2 tablespoons unsalted butter
• 2 tablespoons all‑purpose flour
• 2 cups low‑fat milk (whole works best)
• ½ cup grated Parmesan cheese
• ½ cup shredded mozzarella cheese
• 1 teaspoon Dijon mustard

Seasonings & Garnish

• 3 cloves garlic, minced
• Zest of 1 lemon
• 1 tablespoon fresh lemon juice
• ½ teaspoon dried thyme
• Salt and freshly cracked black pepper, to taste
• 2 tablespoons chopped fresh parsley (optional)

Together these ingredients create a dish that’s both hearty and bright. The butter‑flour roux forms a smooth base that carries the cheese, while the lemon zest lifts the richness. Garlic and thyme add aromatic depth, and the broccoli supplies a pop of green that balances the creamy sauce perfectly.

Step-by-Step Instructions

Preparing the Pasta & Broccoli

Bring a large pot of salted water to a rolling boil. Add the penne and cook for 2 minutes less than the package directs—this “al dente” stage prevents the pasta from becoming mushy during baking. In the last 3 minutes of the pasta cook, toss in the broccoli florets so they soften just enough to retain a slight bite. Drain, rinse briefly with warm water, and set aside.

Cooking the Chicken

While the pasta cooks, heat 1 tablespoon of olive oil in a large skillet over medium‑high heat. Pat the cubed chicken dry, season with salt, pepper, and thyme, then add to the pan in a single layer. Sauté for 4‑5 minutes, turning once, until the pieces are golden on the outside but not fully cooked through. Transfer the chicken to a bowl; it will finish cooking in the oven.

Building the Creamy Sauce

1. Make the roux. In the same skillet, melt 2 tablespoons unsalted butter over medium heat. Sprinkle 2 tablespoons all‑purpose flour over the butter, whisking constantly for 1‑2 minutes until the mixture turns a light golden color. This cooks out the raw flour taste and creates a thickening base.
2. Incorporate the milk. Slowly whisk 2 cups low‑fat milk into the roux, a little at a time, to avoid lumps. Continue stirring until the sauce thickens and coats the back of a spoon, about 4‑5 minutes. The gradual addition ensures a silky texture.
3. Season and enrich. Add 1 teaspoon Dijon mustard, 3 cloves minced garlic, zest of 1 lemon, and 1 tablespoon lemon juice. Stir in ½ cup grated Parmesan and ½ cup shredded mozzarella until melted. Taste and adjust with salt and pepper.

Assembling the Bake

Preheat the oven to 375°F (190°C). In a large mixing bowl, combine the drained pasta‑broccoli mixture, partially cooked chicken, and the creamy sauce. Toss gently to coat everything evenly. Transfer the mixture to a greased 9‑x‑13‑inch baking dish, spreading it into an even layer. Sprinkle an extra handful of mozzarella on top for a golden crust.

Baking & Finishing

Place the dish in the preheated oven and bake for 20‑25 minutes, or until the cheese is bubbling and the edges are lightly browned. Remove from the oven and let it rest for 5 minutes; this rest period allows the sauce to set, making serving cleaner. Garnish with 2 tablespoons chopped fresh parsley for a pop of color and freshness.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

Add a pinch of red‑pepper flakes to the sauce for subtle heat, or stir in a tablespoon of grated Pecorino Romano for extra sharpness. A splash of white wine deglazed after searing the chicken adds depth without overwhelming the creamy base.

Common Mistakes to Avoid

Avoid over‑baking; a 20‑minute bake keeps the cheese creamy while still achieving a golden top. Also, don’t skip the resting step—cutting too early releases the sauce onto the plate, leaving the bake dry.

Pro Tips

Variations

Ingredient Swaps

Swap the chicken for diced turkey breast, pork tenderloin, or firm tofu for a vegetarian twist. Replace broccoli with cauliflower, green beans, or roasted red peppers to change the color palette. Use sharp cheddar or Gruyère instead of mozzarella for a richer cheese profile.

Dietary Adjustments

For a gluten‑free version, use gluten‑free pasta and substitute the flour with cornstarch (1:1 ratio). Dairy‑free diners can replace butter with olive oil, use almond or oat milk, and choose a dairy‑free cheese blend. Keto fans can cut the pasta in half and add cauliflower rice for extra volume without the carbs.

Serving Suggestions

Pair the bake with a simple arugula salad dressed in lemon vinaigrette for a peppery contrast. A side of garlic‑buttered sourdough or warm naan works well to mop up any extra sauce. For a brunch spread, serve alongside fresh fruit and a sparkling mimosa.

Storage Info

Leftover Storage

Allow the bake to cool to room temperature, then transfer portions into airtight containers. Refrigerate for up to 4 days. For longer keeping, freeze individual servings in freezer‑safe bags or containers for up to 3 months; label with the date to track freshness.

Reheating Instructions

Reheat in a preheated 350°F (175°C) oven, covered with foil, for 15‑20 minutes until warmed through. Remove the foil for the last 5 minutes to restore the cheese crust. In a microwave, heat a single portion on medium power for 2‑3 minutes, stirring halfway and adding a splash of milk if the sauce looks dry.
