This Lemon Chicken Sheet Pan Dinner features juicy, golden bone-in chicken thighs roasted alongside tender baby potatoes, zucchini, bell pepper, and red onion — all coated in a bright, garlicky lemon-herb marinade. Everything cooks on a single pan in about 45 minutes, making it one of the easiest and most flavorful weeknight dinners you can put on the table. The high-heat roasting gives the chicken irresistibly crispy skin while the vegetables caramelize beautifully in the pan drippings.

Instructions
Preheat your oven to 425°F (220°C). Line a large rimmed sheet pan with parchment paper or aluminum foil and set aside.
In a large bowl, whisk together 2 tablespoons olive oil, lemon juice, lemon zest, minced garlic, oregano, thyme, smoked paprika, kosher salt, and black pepper until fully combined.
Pat the chicken thighs completely dry with paper towels, then add them to the marinade bowl. Toss well to coat on all sides, tucking some marinade under the skin. Let sit for at least 15–30 minutes, or up to 4 hours refrigerated.
In a medium bowl, combine the halved baby potatoes, zucchini, red bell pepper, and red onion wedges. Drizzle with the remaining 1 tablespoon olive oil, season with a pinch of salt and pepper, and toss to coat evenly.
Spread the seasoned vegetables in a single layer across the prepared sheet pan, then nestle the marinated chicken thighs skin-side up on top. Pour any remaining marinade over the pan and tuck the lemon rounds between the chicken and vegetables.
Roast on the center rack for 40–45 minutes, tossing the vegetables with tongs at the 20-minute mark (keep chicken skin-side up the whole time), until the chicken skin is golden and crispy and an instant-read thermometer reads 165°F (74°C) in the thickest part.
Remove the pan from the oven and let the chicken rest for 5 minutes. Garnish with fresh chopped parsley and an extra squeeze of lemon juice, then serve directly from the pan.
Notes
Pat the chicken dry: Removing surface moisture before marinating is essential for achieving crispy skin — skip this step and the skin will steam instead of roast.
Don't crowd the pan: Overcrowding causes vegetables to steam and turn soggy. Use an 18x13 inch sheet pan or divide between two pans if needed.
Use bone-in, skin-on thighs: They stay juicier and more flavorful during high-heat roasting than boneless, skinless cuts and are more forgiving if slightly overcooked.
Fresh lemon juice only: Bottled lemon juice lacks the brightness and complexity of fresh-squeezed, and you also need the zest — always use fresh lemons.
Using boneless chicken: Reduce cook time to 25–30 minutes and check internal temperature early to prevent drying out.
Vegetable swaps: Broccoli, asparagus, green beans, Brussels sprouts, cherry tomatoes, carrots, or butternut squash all work well — aim for roughly 1-inch pieces for even cooking.
Make-ahead tip: Marinate the chicken in the refrigerator up to 4 hours ahead of time. Cut and prep the vegetables and store separately until ready to assemble and roast.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Chicken can be frozen for up to 3 months.
Reheating: For best results, reheat in a 375°F oven for 15–20 minutes to restore crispy skin. Microwave on medium power if short on time, but skin will soften.
Flavor boost: Add 2 tablespoons of honey to the marinade for a honey-lemon glaze, or add ½ teaspoon red pepper flakes for a spicy kick.
