Prep and timing

This recipe calls for straightforward prep: trim and slice the vegetables, cut the chicken into even pieces so it cooks quickly and uniformly, toss everything together with olive oil, garlic, and ranch seasoning, then spread on a sheet pan and roast. Plan for about 15 minutes of hands-on time and 18–25 minutes of oven time depending on the size of your chicken pieces and how hot your oven runs.

Step-by-step instructions

Follow these steps to make your 15 Minute Sheet Pan Garlic Ranch Chicken and Veggies come together perfectly.

1. Preheat the oven to 425°F (220°C). Line your rimmed baking sheet with foil or parchment paper if you want easier cleanup. This high temperature helps the vegetables caramelize and the chicken to cook quickly, keeping it juicy.
2. Prepare the chicken: Pat the ▢2large boneless skinless chicken breasts dry with paper towels. Cut each breast into roughly 1 to 1½-inch chunks so they cook in the same time as the vegetables. Evenly sized pieces make for consistent cooking and fast roasting.
3. Chop the vegetables: Core and slice the ▢2bell peppers into strips or bite-sized pieces. Peel (if you like) and slice the ▢½small red onion into wedges. Trim the ends from the ▢1medium zucchini and cut it into half-moons or similar-sized chunks. If your ▢1cupbroccoli florets are large, cut them into smaller, bite-sized pieces so they roast evenly with the other vegetables.
4. Make the garlic-ranch toss: In a large mixing bowl combine the ▢3clovesgarlic,crushed or minced with ▢2tablespoonsolive oil and ▢2tablespoonsHidden Valley® Original Ranch Seasoning. Stir until the seasoning is well distributed in the oil and garlic. This mixture will coat both the chicken and the vegetables and infuse everything with bright, savory flavor.
5. Toss chicken and veggies with the seasoning: Add the chicken pieces to the bowl with the garlic-ranch mixture, then add the bell peppers, red onion, zucchini, and broccoli. Use tongs or clean hands to toss everything together until each piece is lightly and evenly coated with the oil, garlic, and ranch seasoning.
6. Arrange on the sheet pan: Spread the seasoned chicken and vegetables in a single layer across the rimmed baking sheet. Make sure pieces are not piled on top of one another—crowding traps steam and prevents good browning. If necessary, use a second sheet pan or remove a few pieces to leave space.
7. Roast in the oven: Transfer the sheet pan to the preheated oven. Roast for 18 to 25 minutes, stirring once halfway through to promote even browning. Cooking time depends on the size of your chicken pieces and your oven. The chicken should register 165°F (74°C) with an instant-read thermometer and the vegetables should be tender with lightly browned edges.
8. Finish and rest: When the chicken reaches the safe internal temperature and the vegetables are roasted to your liking, remove the sheet pan from the oven. Let the chicken rest for 3 to 5 minutes before serving to allow the juices to redistribute.
9. Serve: Transfer the chicken and vegetables to plates or a large serving dish. Optionally, drizzle a little extra olive oil, squeeze a wedge of lemon over the whole pan, or garnish with chopped fresh herbs like parsley or chives for brightness.

Notes and tips for success

• Cut chicken into uniform pieces so it cooks at the same rate as the vegetables.
• Don’t overcrowd the pan. If your pieces are touching too much, they’ll steam instead of roast and won’t get those desirable caramelized edges.
• Use an instant-read thermometer to check doneness—look for 165°F (74°C) in the thickest chicken pieces.
• Swap vegetables freely. Cauliflower, carrots (cut thin), or snap peas are all great alternatives if you want variety.
• Make it meal-prep friendly: Portion leftovers into airtight containers and refrigerate for up to 3 days. Reheat in a preheated 375°F (190°C) oven for about 8–10 minutes to crisp back up, or microwave gently for an easier option.

Flavor variations

• For more heat: Add a pinch of red pepper flakes or a splash of sriracha to the garlic-ranch mixture.
• For citrus brightness: Add the zest of one lemon to the garlic-ranch mix before tossing, and finish with lemon wedges.
• For a smoky twist: Swap half the olive oil for a teaspoon of smoked paprika in the seasoning mix.

What to serve with it

This meal stands well on its own, but if you’d like sides, consider:

• Steamed rice or cauliflower rice for a lighter option.
• Buttery mashed potatoes or garlic-herb couscous for a heartier plate.
• A simple green salad or a crisp loaf of crusty bread to round things out.

Make-ahead and storage

To prep this dish ahead, chop the vegetables and chicken and store them in separate airtight containers in the fridge for up to 24 hours. Combine with the garlic-ranch toss right before spreading on the sheet pan and roasting. Store leftovers in the refrigerator for up to 3 days. Reheat gently to preserve chicken juiciness and vegetable texture.

Nutritional notes

This recipe balances lean protein with a variety of vegetables and uses olive oil for healthy fats. The ranch seasoning adds a bold flavor punch, so you can keep the oil quantity modest without sacrificing taste.

Kitchen-tested troubleshooting

• If your vegetables are underdone while the chicken is cooked through: Next time cut the vegetables slightly smaller or start roasting the vegetables for 5–7 minutes before adding the chicken to the pan.
• If the chicken is dry: Be sure pieces are cut uniformly and check for doneness early; chicken carries on cooking a bit while resting as well.
• If the pan is crowded and nothing browns: Roast in batches or use two pans to keep pieces spread in a single layer.
