Ingredients
For the Parmesan Crusted Chicken:
- 4 boneless, skinless chicken breasts (about 2 pounds)
- 1 cup Parmesan cheese, freshly grated
- ½ cup panko breadcrumbs
- ½ cup regular breadcrumbs
- 3 tablespoons fresh parsley, chopped
- 2 teaspoons garlic powder
- 1 teaspoon Italian seasoning
- ½ teaspoon paprika
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ cup mayonnaise
- 2 tablespoons Dijon mustard
- 2 tablespoons olive oil
For the Sheet Pan Vegetables:
- 1½ pounds baby potatoes, halved
- 2 cups broccoli florets
- 2 cups cherry tomatoes
- 1 red bell pepper, cut into chunks
- 1 yellow bell pepper, cut into chunks
- 1 red onion, cut into wedges
- 3 tablespoons olive oil
- 2 teaspoons Italian seasoning
- 1 teaspoon garlic powder
- Salt and pepper to taste
For Finishing:
- Fresh lemon wedges
- Fresh basil leaves
- Extra Parmesan for serving
- Balsamic glaze (optional)
Instructions
- Prep Your Pan: Preheat oven to 425°F. Line a large sheet pan (at least 18×13 inches) with parchment paper. The parchment prevents sticking and makes cleanup effortless—don’t skip this step.
- Start the Potatoes: Toss halved baby potatoes with 1 tablespoon olive oil, salt, and pepper. Spread on one side of sheet pan. Place in oven for 15 minutes to get a head start—they need longer than other vegetables.
- Prepare Chicken: Pat chicken breasts completely dry. If they’re thick, pound to even 1-inch thickness. This ensures even cooking and prevents dry edges with raw centers.
- Make Coating Station: In shallow bowl, mix Parmesan, both breadcrumbs, parsley, garlic powder, Italian seasoning, paprika, salt, and pepper. In another bowl, whisk mayonnaise with Dijon mustard until smooth.
- Prep Remaining Vegetables: In large bowl, toss broccoli, tomatoes, bell peppers, and onion with remaining 2 tablespoons olive oil, Italian seasoning, garlic powder, salt, and pepper.
- Coat the Chicken: Brush both sides of chicken with mayo-mustard mixture—it acts as delicious glue. Press Parmesan mixture firmly onto both sides, using all the coating. The generous coating creates that restaurant-style crust.
- Arrange the Pan: Remove potatoes from oven. Push to one side. Add seasoned vegetables around perimeter. Place coated chicken breasts in center, not touching each other or vegetables. Drizzle any remaining oil over vegetables.
- Bake to Perfection: Return to oven for 25-30 minutes until chicken reaches 165°F internal temperature and coating is deep golden. Vegetables should be tender and caramelized at edges.
- Rest and Finish: Let rest 5 minutes—this allows juices to redistribute. Squeeze fresh lemon over everything, sprinkle with basil and extra Parmesan. Drizzle with balsamic glaze if desired.
- Serve Family Style: Either serve directly from sheet pan for casual dining, or transfer to platter. The mingled juices from chicken and vegetables create an incredible natural sauce.

The Sheet Pan Revolution
Sheet pan dinners have revolutionized weeknight cooking, and this Parmesan crusted version elevates the concept from convenient to crave-worthy. The genius lies in understanding how different ingredients cook at different rates and arranging them strategically. The chicken acts as the centerpiece, its juices flavoring surrounding vegetables while the vegetables’ moisture creates a humid environment that keeps the chicken juicy.
The high heat is crucial—it creates caramelization on vegetables while crisping the Parmesan crust. Lower temperatures would steam rather than roast, resulting in soggy vegetables and pale chicken. That 425°F sweet spot delivers the Maillard reaction (browning) that develops complex flavors impossible at lower temperatures.
Using parchment paper isn’t just about easy cleanup—it prevents the Parmesan coating from sticking and tearing off, ensures even heat distribution, and allows those caramelized vegetable juices to pool without burning. It’s the difference between Instagram-worthy results and a frustrating mess.
The Parmesan Crust Secret
The combination of mayonnaise and Dijon mustard might raise eyebrows, but it’s genius. Mayonnaise keeps chicken incredibly moist during baking while helping the coating adhere better than egg wash. The oil in mayo also helps the crust brown beautifully. Dijon adds tangy depth that cuts through richness while complementing the Parmesan perfectly.
Using both panko and regular breadcrumbs creates textural interest. Panko provides dramatic crunch and visual appeal with its larger, flakier pieces. Regular breadcrumbs fill gaps between panko, creating a more cohesive coating. This combination delivers superior texture to either alone.
Freshly grated Parmesan makes a noticeable difference. Pre-grated contains anti-caking agents that prevent proper browning and can create a gritty texture. The fresh cheese melts slightly during baking, creating pockets of crispy cheese alongside the crunchy breadcrumbs. It’s worth the extra minute of grating.
Vegetable Strategy and Timing
The staggered cooking approach ensures everything finishes simultaneously. Potatoes need that 15-minute head start because their density requires longer cooking. Starting them first allows proper caramelization without overcooking quicker vegetables.
Vegetable size matters enormously. Uniform cutting ensures even cooking—aim for 1-inch pieces throughout. Broccoli florets should be bite-sized, peppers chunked rather than sliced, onions in wedges that hold together. This consistency prevents some pieces burning while others remain raw.
Cherry tomatoes left whole provide juicy bursts that contrast with other roasted elements. They’ll wrinkle and concentrate in flavor, some bursting to create little pockets of natural sauce. Halving them would release too much moisture, potentially making other vegetables soggy.
Chicken Placement Physics
Centering chicken on the pan isn’t just aesthetic—it’s strategic. The center typically has the most even heat distribution in home ovens. Surrounding vegetables benefit from chicken drippings without sitting directly under them, which would prevent proper caramelization.
That spacing between chicken breasts allows hot air circulation for even cooking and proper crust development. Crowded chicken steams rather than roasts, preventing that gorgeous golden crust. The same principle applies to vegetables—overcrowding equals steaming equals disappointment.
The chicken’s elevation on its coating creates a slight air gap underneath, preventing the bottom from becoming soggy. This is why we coat both sides generously—it’s not just about flavor but also about creating proper heat circulation for even cooking.
Temperature and Doneness
While 165°F is the safe internal temperature for chicken, placement of the thermometer matters. Insert horizontally into the thickest part, avoiding contact with the pan. The temperature will rise 5 degrees during resting, so removing at 160°F prevents overcooking.
Visual cues complement temperature readings. The coating should be deep golden brown, almost amber in spots. Juices running from chicken should be clear, not pink. The vegetables should show caramelized edges—those brown bits equal concentrated flavor.
That 5-minute rest isn’t optional—it’s transformative. Cutting immediately causes juices to flood out, leaving dry meat. Resting allows juices to redistribute throughout the meat. Cover loosely with foil if your kitchen is cold, but usually the residual heat is sufficient.
Flavor Variations
Mediterranean Style: Add kalamata olives, artichoke hearts, and sun-dried tomatoes to vegetables. Finish with feta crumbles and fresh oregano. Replace Italian seasoning with Greek seasoning blend.
Tex-Mex Twist: Use crushed tortilla chips in coating, add cumin and chili powder. Include corn and black beans with vegetables. Finish with cilantro, lime, and pepper jack cheese.
Asian Fusion: Mix panko with sesame seeds, add ginger to coating. Use snap peas, baby corn, and mushrooms. Finish with teriyaki glaze and scallions.
Autumn Harvest: Replace summer vegetables with butternut squash, Brussels sprouts, and sweet potatoes. Add sage to coating, finish with dried cranberries and pecans.
Lemon Herb: Add lemon zest to coating, use asparagus and zucchini. Finish with fresh dill and extra lemon. Light and bright for spring dinners.
Troubleshooting Common Issues
“Coating fell off”: Chicken wasn’t dry enough or coating wasn’t pressed firmly. Pat chicken thoroughly, press coating with palm pressure. The mayo mixture should be thick enough to act as glue.
“Vegetables burnt, chicken undercooked”: Oven runs hot or vegetables cut too small. Reduce temperature 25°F, cut vegetables larger. Use oven thermometer to verify actual temperature.
“Bottom of chicken soggy”: Too much moisture from vegetables or pan overcrowded. Ensure vegetables aren’t wet, maintain proper spacing. Consider elevating chicken on wire rack over vegetables.
“Potatoes still hard”: Not enough head start or cut too large. Smaller pieces cook faster. Increase preliminary cooking time or cut into smaller pieces next time.
“Lacking flavor”: Under-seasoned at multiple points. Season chicken, coating, and vegetables separately. The high heat diminishes flavors, so season generously.
Make-Ahead Magic
This meal preps beautifully for busy weeknights. Coat chicken in the morning, store covered in refrigerator. Chop vegetables and store in containers. Mix coating ingredients. Come dinnertime, assembly takes 5 minutes.
The coated chicken actually benefits from refrigerator time—the coating adheres better and flavors meld. Just bring to room temperature 20 minutes before baking for even cooking. Vegetables can be tossed with oil and seasonings up to 2 hours ahead.
Leftovers transform wonderfully. Slice chicken for sandwiches, chop for salads, or dice for pasta. Roasted vegetables become soup, frittata filling, or grain bowl toppings. Nothing goes to waste with versatile components.
Scaling for Crowds
This recipe doubles easily using two sheet pans. Rotate pans halfway through cooking for even browning. For larger groups, cook in batches, keeping finished pans warm in 200°F oven. The beauty of sheet pan dinners is easy multiplication.
For smaller households, halve recipe or cook full amount for planned leftovers. Individual portions reheat well in toaster oven, maintaining crispy coating better than microwave. The vegetables actually improve overnight as flavors concentrate.
Sheet Pan Selection
Pan quality affects results significantly. Heavy-duty aluminum distributes heat evenly, preventing hot spots. Dark pans cook faster—reduce temperature 25°F. Avoid glass for this high-heat application. The pan should have raised edges to contain juices.
Size matters—overcrowding defeats the purpose. Standard half-sheet pans (18×13 inches) work perfectly for serving 4. Smaller pans require cooking in batches. The investment in quality sheet pans pays dividends in consistent results.

Nutritional Benefits
Despite its indulgent appearance, this dinner provides balanced nutrition. Lean chicken breast delivers protein, vegetables offer fiber and vitamins, potatoes provide satisfying carbohydrates. The one-pan method requires minimal added fats while maximizing flavor through roasting.
Simple swaps create lighter versions. Greek yogurt replaces some mayonnaise, extra vegetables reduce portion sizes, cauliflower substitutes for some potatoes. Small changes maintain satisfaction while reducing calories.
The Weeknight Game-Changer
This recipe exemplifies why sheet pan dinners have become weeknight staples. Minimal prep, passive cooking time, easy cleanup—it checks every box for busy families. Yet the results rival labor-intensive meals, proving that convenience doesn’t mean compromising quality.
The technique teaches valuable cooking principles: ingredient timing, heat management, flavor building through browning. Master this recipe and you’ll understand sheet pan methodology applicable to countless variations. It’s not just dinner—it’s kitchen education.
Wine and Beverage Pairings
The rich Parmesan crust pairs beautifully with crisp white wines. Pinot Grigio’s acidity cuts through richness while complementing herbs. Chardonnay echoes buttery notes in the coating. For red lovers, light Pinot Noir won’t overpower the delicate chicken.
Non-alcoholic options include sparkling water with lemon to cleanse the palate, or iced tea for that American dinner classic. The vegetables’ natural sweetness even makes this meal kid-friendly with just milk or juice.
Serving Suggestions
Present directly on the sheet pan for casual family dinners—there’s something honest and inviting about serving from the cooking vessel. Line with fresh parchment for cleaner presentation. The mingled juices create natural sauce that shouldn’t be wasted.
For company, transfer to a large white platter, arranging chicken over vegetables. Drizzle with pan juices and finish with fresh herbs. The colors pop against white ceramic, creating restaurant-worthy presentation with minimal effort.
Individual plating works beautifully too. Nestle chicken against vegetable mound, drizzle with any accumulated juices, finish with fresh Parmesan shavings. A lemon wedge and herb sprig complete the professional look.
