This Ranch Chicken Sheet Pan Dinner is the ultimate easy weeknight meal — juicy, bone-in chicken thighs and colorful roasted vegetables all seasoned with bold ranch flavoring and cooked together on a single pan. With minimal prep, just 35 minutes of roasting time, and virtually no cleanup, it delivers big comfort food flavor without any of the fuss.

Instructions
Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper or foil and set aside.
In a small bowl, combine the ranch seasoning packet, garlic powder, onion powder, smoked paprika, salt, and black pepper. Stir until evenly mixed and set aside.
Pat the chicken thighs completely dry with paper towels, then drizzle with 1 tablespoon olive oil and rub half of the seasoning blend all over, including under the skin. Arrange skin-side up on one side of the prepared baking sheet.
In a large bowl, toss the halved potatoes, broccoli florets, baby carrots, and bell pepper with the remaining 2 tablespoons of olive oil and the remaining seasoning blend until evenly coated. Spread in a single layer around the chicken on the sheet pan.
Place the sheet pan on the center rack and roast at 425°F for 30 to 35 minutes, stirring the vegetables at the 20-minute mark for even browning.
The chicken is done when an instant-read thermometer inserted into the thickest part of a thigh reads 165°F (74°C) and the skin is golden brown. If needed, broil for 2 to 3 minutes for extra crispy skin.
Remove from the oven and let the chicken rest for 5 minutes before serving. Garnish with freshly chopped parsley if desired and serve directly from the pan.
Notes
Pat the chicken dry: Always pat chicken skin completely dry with paper towels before seasoning — this is the single most important step for achieving crispy skin.
Don't crowd the pan: Use a full 18x13 inch half-sheet pan. If your pan is smaller, spread the ingredients across two pans to avoid steaming.
Boneless chicken option: Boneless, skinless chicken thighs work well — reduce cook time to 22 to 25 minutes and check temperature early.
Chicken breasts: Boneless, skinless chicken breasts can be substituted; reduce roasting time to 20 to 22 minutes as they dry out faster.
Vegetable swaps: Zucchini, asparagus, green beans, cauliflower, mushrooms, or sweet potatoes all work. Add softer vegetables during the last 15 minutes of cooking.
Extra crispy skin tip: If skin is not as golden as desired when the chicken hits 165°F, broil on high for 2 to 3 minutes — watch closely to avoid burning.
Make-ahead option: Season the chicken and toss the vegetables up to 24 hours ahead, store separately in the fridge, and roast when ready.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat on a baking sheet at 375°F for 10 to 15 minutes for best results.
Freezing: The cooked chicken thighs freeze well for up to 3 months. Vegetables are best enjoyed fresh or refrigerated, as they can become mushy after freezing.
Flavor variations: Add 2 tablespoons of hot sauce to the oil for a buffalo ranch version, or stir in the zest and juice of one lemon for a bright lemon ranch twist.
