Why You'll Love This Recipe

Ingredients

For this bake, fresh, high‑quality ingredients make all the difference. The chicken breasts provide a lean, juicy foundation, while the broccoli brings a pop of color and a gentle crunch. Whole‑wheat penne holds the sauce beautifully, and the three‑cheese blend creates a luxurious, creamy coating. A splash of milk and a dash of Dijon mustard lift the sauce, and the herbs add a fragrant finish that ties everything together.

Main Ingredients

• 2 large boneless, skinless chicken breasts, cubed (≈½ lb)
• 2 cups fresh broccoli florets
• 12 oz whole‑wheat penne pasta

Cheese Sauce

• 2 cups shredded mozzarella cheese
• 1 cup shredded sharp cheddar cheese
• ½ cup grated Parmesan cheese
• 1 ½ cups whole‑milk
• 2 tablespoons unsalted butter
• 2 tablespoons all‑purpose flour
• 1 teaspoon Dijon mustard

Seasonings & Garnish

• 1 teaspoon garlic powder
• ½ teaspoon smoked paprika
• Salt and freshly ground black pepper, to taste
• 2 tablespoons chopped fresh parsley

Each element plays a role: the chicken absorbs the buttery sauce, the broccoli adds a bright, slightly bitter contrast, and the pasta acts as a neutral canvas that soaks up every cheesy nuance. The flour‑butter roux thickens the sauce without lumps, while the mustard adds a subtle tang that cuts through richness. Together they create a cohesive, comforting bake that feels both indulgent and balanced.

Step-by-Step Instructions

Preparing the Ingredients

Begin by bringing a large pot of salted water to a boil. While the water heats, cube the chicken into bite‑size pieces and season them with garlic powder, smoked paprika, salt, and pepper. Toss the broccoli florets in a bowl with a drizzle of olive oil, a pinch of salt, and set aside. This pre‑seasoning ensures every bite is flavorful from the start.

Cooking Pasta & Chicken

1. Cook the Pasta. Add the penne to the boiling water and cook al dente according to package instructions (usually 9–11 minutes). Drain, drizzle with a teaspoon of olive oil to prevent sticking, and set aside.
2. Sear the Chicken. In a large skillet over medium‑high heat, melt 1 tablespoon butter. Add the seasoned chicken cubes in a single layer; let them sear undisturbed for 3 minutes, then flip and cook another 2 minutes until lightly browned but not fully cooked through. Remove and set aside.
3. Blanch the Broccoli. While the chicken browns, drop the broccoli into the boiling pasta water for the last 2 minutes of cooking. This brightens the color and softens the stems without overcooking. Drain with the pasta.

Making the Cheesy Sauce

1. Create a Roux. In the same skillet, reduce heat to medium and add the remaining 1 tablespoon butter. Once melted, whisk in 2 tablespoons flour. Cook, stirring constantly, for 1‑2 minutes until the mixture turns a light golden hue—this eliminates raw flour taste.
2. Incorporate Milk. Gradually whisk in 1½ cups whole‑milk, ensuring no lumps form. Continue stirring until the sauce thickens and coats the back of a spoon, about 4‑5 minutes.
3. Add Cheese & Flavor. Reduce heat to low, then stir in mozzarella, cheddar, and Parmesan until melted and smooth. Mix in 1 teaspoon Dijon mustard for a subtle tang, and adjust seasoning with additional salt and pepper if needed.

Assembling the Bake

Preheat the oven to 375°F (190°C). In a large mixing bowl, combine the cooked penne, seared chicken, blanched broccoli, and the cheese sauce. Toss gently until everything is evenly coated. Transfer the mixture to a greased 9×13‑inch baking dish, spreading it into an even layer. Sprinkle a final handful of Parmesan on top for extra crust.

Baking & Finishing

Place the dish in the preheated oven and bake for 20‑25 minutes, or until the sauce is bubbling and the top is golden‑brown. Remove from the oven, let it rest for 5 minutes, then garnish with chopped fresh parsley. The resting time allows the sauce to set, making serving cleaner and preserving the creamy texture.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

Finish the bake with a squeeze of fresh lemon juice for brightness, or stir in a pinch of red‑pepper flakes for gentle heat. A drizzle of extra‑virgin olive oil just before serving adds a silky finish.

Common Mistakes to Avoid

Avoid stirring the sauce too aggressively once the cheese melts; this can cause a grainy texture. Also, never add the cheese directly to a scorching pan—reduce the heat first to keep the sauce smooth and glossy.

Pro Tips

Variations

Ingredient Swaps

Replace chicken with diced turkey breast, cooked ham, or firm tofu for a vegetarian twist. Swap broccoli for cauliflower, green beans, or roasted red peppers. If you love extra spice, stir in a tablespoon of chipotle in adobo sauce into the cheese mixture.

Dietary Adjustments

For gluten‑free, use gluten‑free pasta and ensure the flour is a certified blend (or substitute cornstarch). To make it dairy‑free, swap butter for olive oil, use dairy‑free cheese alternatives, and replace milk with almond or oat milk. Keto diners can cut the pasta in half and increase the cheese proportion, or serve over spiralized zucchini noodles.

Serving Suggestions

Pair the bake with a simple mixed‑green salad dressed with lemon vinaigrette, or serve alongside buttery garlic toast for extra crunch. A side of fresh fruit salad balances the richness, making the meal feel complete for brunch or breakfast.

Storage Info

Leftover Storage

Allow the bake to cool to room temperature (no more than two hours), then transfer portions to airtight containers. Refrigerate for up to four days. For longer keeping, wrap tightly in plastic wrap followed by aluminum foil and freeze for up to three months. Label with the date for easy reference.

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 golden crust. In a pinch, microwave individual servings on medium power for 2‑3 minutes, adding a splash of milk to keep the sauce silky.
