Ingredients

• 6 bone-in, skin-on chicken thighs (about 2 lbs)
• 1 medium eggplant, diced into 1-inch cubes
• 2 medium zucchini, halved lengthwise and sliced into 1/2-inch half-moons
• 1 red bell pepper, diced into 1-inch pieces
• 1 yellow onion, diced into 1-inch pieces
• 4 cloves garlic, minced
• 1 pint cherry tomatoes (or 2 large tomatoes, chopped)
• 3 tablespoons olive oil, divided
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1/2 teaspoon dried rosemary
• 1 teaspoon salt, divided
• 1/2 teaspoon black pepper, divided
• 2 tablespoons fresh basil, chopped (for garnish)
• Optional: 1 tablespoon balsamic vinegar for drizzling

Optional Substitutions

• Vegetable swaps: Use yellow squash instead of zucchini, or add mushrooms for an earthy flavor. You can also add fennel or asparagus.
• Chicken: Boneless, skinless chicken thighs work too, but reduce cooking time by about 5 minutes. Chicken breasts can be used, but they may dry out; check for doneness at 165°F.
• Tomato swap: Canned diced tomatoes (drained) can replace fresh in a pinch, though fresh cherry tomatoes roast better.
• Herbs: Fresh herbs like basil, parsley, or rosemary can be used instead of dried. Use about three times the amount if fresh.
• Oil: Avocado oil or grapeseed oil are good neutral substitutes for olive oil.
• Garlic: Use 1 teaspoon garlic powder if you don't have fresh garlic, but fresh is preferred for flavor.
• No eggplant? Simply omit it or add more zucchini and bell pepper.
• Add protein: Toss in chickpeas or white beans for extra fiber and protein.

Instructions

1. Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper or foil for easy cleanup.
2. Pat the chicken thighs dry with paper towels. This helps the skin get crispy. Season both sides with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
3. In a large bowl, combine the diced eggplant, zucchini, bell pepper, onion, and cherry tomatoes. Add the minced garlic, dried thyme, oregano, rosemary, 2 tablespoons olive oil, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Toss well to coat evenly.
4. Spread the vegetables in a single layer on the prepared baking sheet, leaving a little space between pieces for even roasting.
5. Arrange the chicken thighs, skin side up, among the vegetables. If you have extra space, place the chicken directly on the pan; otherwise, nestle them into the vegetables. Drizzle the remaining 1 tablespoon olive oil over the chicken skin.
6. Roast for 35-40 minutes, or until the chicken skin is golden and crispy and the internal temperature reaches 175°F to 185°F (for bone-in thighs). The vegetables should be tender and lightly charred at the edges.
7. If you like, drizzle with balsamic vinegar during the last 5 minutes for extra tang.
8. Remove from the oven and let rest for 5 minutes. Garnish with fresh basil and serve.

Pro Tips

• Dry the chicken well: Moisture is the enemy of crispy skin. Pat the chicken thoroughly before seasoning.
• Cut vegetables uniformly: This ensures they cook at the same rate. Dice them into similarly sized pieces, about 1 inch.
• Don't overcrowd the pan: Use a large sheet pan and spread everything in a single layer. Overcrowding steams the vegetables instead of roasting them.
• Use a meat thermometer: Chicken thighs are best at 175°F to 185°F for tender, juicy meat. The higher temperature breaks down connective tissue.
• Season generously: Vegetables need enough salt and oil to become flavorful. Don't be shy.
• Swap the pan: If you don't have a rimmed baking sheet, use a large roasting pan. The rim helps contain juices.
• Add a crunch: For extra texture, sprinkle breadcrumbs over the vegetables before roasting.
• Let it rest: Allowing the chicken to rest after roasting redistributes juices.
• Line your pan: Parchment paper or foil makes cleanup effortless.

Variations and Substitutions

• Provencal version: Add a tablespoon of herbes de Provence instead of individual herbs for a classic French twist.
• Spicy kick: Sprinkle red pepper flakes over the chicken before roasting, or add a diced jalapeño to the vegetables.
• Cheesy finish: In the last 5 minutes, top the chicken with shredded Parmesan or crumbled feta cheese.
• Add olives: Toss in a handful of black or Kalamata olives for a briny pop.
• Make it a meal: Serve over couscous, quinoa, or creamy polenta to soak up the juices.
• Summer twist: Add sliced peaches or nectarines during the last 10 minutes for a sweet-savory note.
• One-pan with potatoes: Add diced potatoes (parboiled for 5 minutes) to the vegetables for a heartier meal.
• Vegan version: Omit chicken, double the vegetables, and add chickpeas or tofu for protein.

Storage and Reheating

Fridge

Store leftovers in an airtight container in the refrigerator for up to 4 days. The vegetables may soften, but the flavors will meld beautifully.

Freezer

Place cooled leftovers in a freezer-safe container or bag for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating

For best results, reheat in a 350°F oven for 10-15 minutes or until warmed through. The microwave works too, but the chicken skin will lose its crispness. To revive crispiness, reheat in a hot skillet with a little oil.

FAQ

Can I use boneless chicken thighs? Yes, boneless thighs work well. Reduce roasting time by 5-10 minutes and check for doneness at 165°F.

Can I make this dairy-free? The recipe is already dairy-free as written. Just skip any cheese variations.

Do I need to peel the eggplant? No, the skin is edible and adds texture. Just wash it well.

Can I prep this ahead of time? Yes, you can chop the vegetables and season the chicken up to a day ahead. Store in the fridge separately.

What if my vegetables are browning too quickly? If the vegetables are browning faster than the chicken, lightly cover the pan with foil for the last 10 minutes.

Can I use frozen vegetables? Fresh vegetables roast better; frozen will release too much moisture and become soggy. If using frozen, thaw and pat dry first.

How do I know when the chicken is done? Use a meat thermometer inserted into the thickest part of the thigh (avoiding bone). Bone-in thighs should reach 175°F to 185°F.

What should I serve with this? This dish is complete on its own, but it's wonderful with crusty bread, rice, pasta, or a simple green salad.

Can I double the recipe? Yes, but use two sheet pans to avoid overcrowding. Rotate pans halfway through baking.
