1½ lbs chicken breast (about 3–4 pieces), approximately 1 inch thick
2 tablespoons olive oil (for chicken)
2 garlic cloves, minced (for chicken)
⅓ cup grated parmesan (for chicken)
⅓ cup breadcrumbs, Italian or plain
½ teaspoon cracked pepper
½ to ¾ teaspoon sea salt
2 lbs red potatoes, cut into bite-sized pieces
1 to 2 garlic cloves, minced (for potatoes)
2 tablespoons olive oil (for potatoes)
2 tablespoons grated parmesan (for potatoes)
Salt and pepper to taste (for potatoes)
1 lb fresh green beans, ends trimmed
1 tablespoon olive oil (for green beans)
1 garlic clove, minced (for green beans)
1 tablespoon grated parmesan (for green beans, optional)
Salt and pepper to taste (for green beans)
Instructions
Preheat oven to 425°F. Line a large sheet pan (at least 18×13 inches) with parchment paper or spray with cooking oil.
In a medium bowl, toss potatoes with garlic, olive oil, parmesan, salt, and pepper until evenly coated. Spread on one-third of the sheet pan in a single layer and bake for 10-15 minutes until lightly golden.
While potatoes roast, combine chicken with olive oil, garlic, parmesan, breadcrumbs, pepper, and salt in the same bowl. Press coating onto all sides of chicken pieces. If chicken is thicker than 1 inch, pound to even thickness.
Carefully remove hot pan from oven using oven mitts. Place coated chicken on another third of the pan, keeping separate from potatoes. Return to oven immediately.
Quickly toss green beans with olive oil, garlic, optional parmesan, salt, and pepper. Remove pan from oven and add green beans to remaining section in a single layer.
Bake for 25 minutes or until chicken reaches internal temperature of 165°F. Parmesan crust should be golden brown, potatoes fork-tender with crispy edges, and green beans tender-crisp.
For extra crispy results, turn oven to broil on high for 4-5 minutes. Watch closely to prevent burning.
Remove from oven and let rest 3-4 minutes before serving to allow juices to redistribute.
Notes
Chicken breast thickness affects cooking time significantly. Thicker pieces may need extra 5-10 minutes. Always use meat thermometer to verify 165°F internal temperature for food safety.
For crispier coating on all sides, use a wire cooling rack on the sheet pan to elevate chicken and allow airflow underneath.
Can substitute boneless, skinless chicken thighs for breasts. Ensure they also reach 165°F internal temperature.
Fresh green beans give best texture. If using frozen, thaw completely and pat very dry with paper towels first.
Use 18×13 inch sheet pan (half-sheet size) to avoid crowding and ensure proper roasting.
