Baked Boneless Chicken Thighs and Veggies

This one-pan dinner features tender boneless, skinless chicken thighs — they stay juicier than breasts — and a mix of colorful vegetables, all coated in a simple Italian seasoning blend made with olive oil and red wine vinegar. The chicken and vegetables can be marinated together up to a day in advance for extra flavor and even faster assembly on the day you plan to bake.

Sheet Pan Chicken Ingredients

• Italian seasoning/marinade: kosher salt, onion powder, dried oregano and dried basil, thyme, a pinch of sugar (optional—omit for Whole30/Paleo), black pepper, crushed garlic, olive oil and red wine vinegar.
• Chicken: Eight boneless, skinless chicken thighs (about 4 oz each), trimmed of excess fat and lightly seasoned with salt.
• Vegetables: Zucchini (diced into 1-inch pieces), carrots (peeled and diced), red and yellow bell peppers (cut into 1-inch pieces) and a red onion (cut into 1-inch pieces).
• Garnish: Fresh flat-leaf parsley, chopped.

How to Make Baked Chicken Thighs

1. Make the marinade: Combine the salt, onion powder, oregano, basil, thyme, sugar (if using), black pepper, crushed garlic, olive oil and red wine vinegar in a large bowl to form the Italian-style dressing.
2. Marinate: Season the chicken thighs with the indicated salt, add the chicken and all the vegetables to the bowl with the dressing, and toss until everything is well coated. Let the mix marinate for at least 30 minutes, or refrigerate up to overnight. Marinating the vegetables with the chicken is fine, since everything will be baked.
3. Prepare to roast: Preheat the oven to 450°F (230°C). Line two large rimmed sheet pans with foil or parchment or spray them lightly with cooking spray for easy cleanup. Arrange a center rack and a lower-third rack in the oven if you will use both pans at once.
4. Arrange in a single layer: Spread the chicken and vegetables across the prepared pans so pieces do not touch — you want roast and caramelize, not steam.
5. Roast: Bake for about 20 minutes, then turn both the chicken and the vegetables and roast another 10 minutes, or until the chicken is cooked through and the vegetables are tender and lightly browned. Remove from the oven, sprinkle with chopped parsley and serve.

What Pairs Well with Italian Chicken?

This sheet pan chicken and vegetables are a complete, balanced meal on their own, but you can add a grain or starch if you want more bulk. Good options include cooked quinoa or brown rice, which soak up any pan juices. Mashed potatoes or roasted baby potatoes are also excellent choices. This recipe doesn’t produce a lot of sauce, so plain pasta is less ideal unless you plan to serve it with a separate sauce or tossed greens.

How to Freeze

Leftovers store well. Keep extra chicken and vegetables in the refrigerator for up to three days. For longer storage, let the cooked dish cool completely, then portion into freezer-safe containers and freeze for up to three months. To reheat, thaw overnight in the refrigerator and warm in a 325°F oven for about 20 minutes or until heated through.

Variations and Tips

• Paleo / Whole30: Omit the sugar in the seasoning to keep this compliant.
• Herb swaps: If you don’t have fresh herbs, dried thyme works in the mix; dried rosemary or parsley can also be used in place of other herbs for a slightly different flavor.
• Vegetable swaps: Use whatever you have on hand—cauliflower, broccoli or Brussels sprouts are all excellent roasted alternatives.
• Different chicken cuts: If you prefer chicken breasts, reduce total baking time so they don’t dry out (about 20 minutes total). For bone-in thighs, remove vegetables after roughly 30 minutes and continue baking the thighs an additional 10 minutes or until cooked through.
• For crisper vegetables: Make sure pieces are evenly spaced and not crowded on the pan. High heat and space around each piece encourage browning.
