Step-by-Step Instructions

1️⃣ Prep & Preheat

• Preheat oven to 400°F (200°C).
• Line a large rimmed sheet pan with parchment paper.
• Avoid crowding — if needed, use two pans.

2️⃣ Season the Potatoes

• In a large bowl, toss potatoes with:
  • 2.5 tbsp olive oil
  • 1 tsp kosher salt
  • ½ tsp black pepper
  • ½ tsp paprika
  • ½ tsp dried oregano
  • ½ tsp dried thyme
  • half the minced garlic
• Spread evenly on half of the sheet pan.
• Roast 15–20 minutes to give them a head start.

3️⃣ Prep the Chicken

• In the same bowl (no need to wash it), combine:
  • 2.5 tbsp olive oil
  • remaining minced garlic
  • ½ cup grated Parmesan
  • 1.5 tsp dried oregano
  • 1 tsp dried thyme
  • 1 tsp dried parsley
  • 1 tsp paprika
  • ½ tsp kosher salt
  • ½ tsp black pepper
  • red pepper flakes (optional)
• Pat chicken dry with paper towels.
• Add to the bowl and coat well with the garlic-Parmesan paste.

4️⃣ Roast It All

• After potatoes roast for 15–20 minutes, remove the pan.
• Arrange chicken on the other half of the sheet pan, making sure nothing overlaps too much.
• Return to oven and roast another 20–25 minutes, or until:
  • chicken reaches 165°F (74°C) internal temperature
  • potatoes are golden and crisp

Optional: Broil for the last 1–3 minutes for extra browning, watching closely.

5️⃣ Rest & Serve

• Let the chicken rest 5–10 minutes to redistribute juices.
• Sprinkle with fresh parsley and extra Parmesan.
• Serve with lemon wedges for a bright finish.

FAQ

Can I use chicken thighs instead of breasts?
Yes! Boneless thighs work beautifully, adjust cook time to ~25–30 min until 170–175°F.

Can I add other veggies?
Sure! Try bell peppers, broccoli, Brussels sprouts, or red onions. Add them to the pan during the last 20 minutes.

Why is my chicken dry?
Most common reason is uneven thickness or overcooking. Always pound to ¾ inch and use a thermometer.

How do I store leftovers?
Refrigerate in an airtight container up to 4 days. Reheat in oven or air fryer for best texture.

Can I freeze this?
Yes. Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight and reheat.

Ingredient Spotlight: Parmesan

Did you know authentic Parmigiano-Reggiano is aged for 12–24 months and made only in specific regions of Italy? Its rich, nutty flavor comes from traditional methods dating back centuries. That’s why fresh-grated Parmesan always beats the pre-shredded stuff — you’ll taste the difference in every bite.

Health Benefits

✅ Garlic — antibacterial, supports immunity
✅ Olive oil — heart-healthy fats
✅ Chicken breast — lean protein
✅ Potatoes — fiber and potassium

Balanced and satisfying!
