Sheet-Pan Parmesan Chicken & Broccoli

Some nights, dinner needs to be fast, easy, and something the whole family will actually eat. This Sheet-Pan Parmesan Chicken & Broccoli checks every box: juicy seasoned chicken, crispy-edged broccoli, and a golden Parmesan crust — all roasted together on one pan in about 30 minutes with barely any cleanup.

The trick is all in the timing. The broccoli goes in first for a head start, then the Parmesan-coated chicken joins the pan so everything finishes at the same moment. The cheese melts into the chicken for a savory, slightly crispy coating, and the broccoli florets catch those delicious browned bits around the edges.

With around 38 grams of protein per serving and just one pan to wash, this is the weeknight dinner that makes healthy eating feel like the easy choice — because it is. Add a squeeze of fresh lemon at the end and dinner is done.

Seriously juicy chicken. Cutting the chicken into even pieces and giving the broccoli a head start means nothing overcooks. The Parmesan coating locks in moisture and adds a savory, golden crust.

Ingredients

• 1 1/2 lbs boneless, skinless chicken breasts, cut into 1-inch pieces
• 5 cups broccoli florets (about 2 medium heads)
• 3 tablespoons olive oil, divided
• 1/2 cup freshly grated Parmesan cheese, divided
• 2 tablespoons panko breadcrumbs (optional, for extra crunch)
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• 1/2 teaspoon smoked paprika
• 3/4 teaspoon salt
• 1/2 teaspoon black pepper
• Lemon wedges, for serving

Instructions

1. Preheat the oven to 425°F. Line a large rimmed sheet pan with foil or parchment paper for easy cleanup.
2. In a large bowl, toss the broccoli florets with 2 tablespoons of the olive oil, half of the garlic powder, half of the Italian seasoning, half of the salt, and half of the pepper.
3. Spread the broccoli in a single layer on the prepared sheet pan, leaving space between the florets so they roast instead of steam.
4. Roast the broccoli for 8 minutes while you prep the chicken.
5. In the same bowl, toss the chicken pieces with the remaining 1 tablespoon of the olive oil, the remaining garlic powder, Italian seasoning, smoked paprika, salt, and pepper. Add 1/4 cup of the Parmesan and toss to coat.
6. Push the broccoli to the edges of the pan and arrange the chicken in the center in a single layer. Sprinkle the remaining 1/4 cup Parmesan and the panko (if using) evenly over the chicken and broccoli.
7. Return the pan to the oven and roast for 12 to 14 minutes, until the chicken is cooked through (165°F internally) and the Parmesan is golden.
8. Squeeze fresh lemon over everything and serve immediately.

Tips and Variations

Don’t crowd the pan. This is the number one rule of sheet-pan cooking. Space between the pieces lets hot air circulate so everything roasts and crisps. If your pan is small, use two pans.

Cut chicken evenly. Uniform 1-inch pieces cook at the same rate, so you won’t have some pieces dry while others are undercooked. Chicken tenders also work great.

Use freshly grated Parmesan. Pre-shredded Parmesan contains anti-caking agents that keep it from melting smoothly. A wedge of Parmesan and a box grater make all the difference in that golden crust.

Swap the vegetable. Cauliflower florets, green beans, asparagus, or Brussels sprout halves all roast beautifully alongside the chicken. Adjust the head-start time: asparagus and green beans need less, cauliflower needs about the same as broccoli.

Add a finishing touch. A drizzle of balsamic glaze, a sprinkle of red pepper flakes, or a handful of fresh basil takes this from simple to restaurant-worthy in seconds.

Make it a full meal. Serve over rice, quinoa, or buttered noodles to soak up the savory pan juices, or stuff it into wraps for easy lunches the next day.

FAQs

Can I use chicken thighs instead of breasts?

Yes — boneless, skinless chicken thighs work wonderfully and stay extra juicy. Cut them into 1-inch pieces and add 2 to 3 minutes to the roasting time, since thighs take slightly longer to cook through.

How do I know the chicken is done?

The most reliable way is an instant-read thermometer: chicken is done at 165°F. Visually, the pieces should be opaque all the way through with no pink, and the juices should run clear.

Why is my broccoli soggy instead of crispy?

Usually it’s one of three things: the pan was overcrowded, the florets were still wet when they went in, or the oven wasn’t fully preheated. Pat the broccoli dry, spread it out in a single layer, and make sure your oven hits 425°F before the pan goes in.

Can I meal prep this sheet-pan dinner?

Definitely. Portion the cooked chicken and broccoli into containers and refrigerate for up to 4 days. Reheat in a 375°F oven or air fryer for 5 to 7 minutes to re-crisp — the microwave works too, though the coating won’t stay as crunchy.

Fast, flavorful, and practically self-cleaning, this sheet-pan Parmesan chicken and broccoli is weeknight cooking at its best. One pan, 30 minutes, dinner done — and a golden Parmesan crust that’ll have everyone asking for seconds.
