Baked Chicken and Zucchini (High-Heat Version)

This baked chicken and zucchini comes out of the oven golden and juicy every time — no soggy vegetables, no dry meat. The secret is high heat (425°F) and plenty of breathing room on the pan. Ready in 30 minutes, it's the weeknight dinner that actually delivers.

Equipment

  • Rimmed sheet pan (half-sheet)
  • Parchment Paper
  • Tongs
  • Instant-read thermometer

Ingredients
  

  • 4 boneless skinless chicken thighs (or breasts)
  • 2 medium zucchini, cut into spears
  • 3 tablespoons olive oil
  • 4 cloves garlic, smashed
  • 1 teaspoon dried oregano
  • 1/2 teaspoon red pepper flakes
  • Salt and black pepper (generous pinches)
  • Lemon wedges for serving
  • Fresh parsley for serving
  • Grated parmesan (optional, for serving)

Instructions
 

  • Preheat your oven to 425°F. Line a rimmed sheet pan with parchment paper.
  • Pat the chicken and zucchini spears very dry with paper towels. This is the single most important step for getting caramelization instead of steaming.
  • In a large bowl, toss the chicken and zucchini with the olive oil, smashed garlic, oregano, red pepper flakes, 1 teaspoon salt, and plenty of black pepper. Make sure everything is evenly coated.
  • Arrange the chicken on the prepared sheet pan, leaving space between each piece. Place the zucchini spears in a single layer around the chicken, not touching. If they’re crowded, they’ll steam.
  • Bake for 20-25 minutes, until the chicken reaches an internal temperature of 165°F (for breasts) or 175°F (for thighs). The zucchini should be tender and golden on the edges. For extra color, broil for 2-3 minutes, watching closely.
  • Squeeze fresh lemon juice over the top, sprinkle with parsley and parmesan if using. Let rest for 5 minutes before serving.

Notes

Dry your ingredients thoroughly — it's the difference between caramelized edges and steamed food. Don't crowd the pan; use two pans if needed. Cut zucchini spears about 1/2-inch thick for even cooking. Use an instant-read thermometer: pull chicken breasts at 165°F, thighs at 175°F. For meal prep, store chicken and zucchini separately in airtight containers up to 4 days. Reheat in a 400°F oven or air fryer for 5-7 minutes to re-crisp. Only freeze the chicken (zucchini gets mushy).
