Ingredients Youll Need

4 chicken breasts
1 cup grated Parmesan cheese
2 cups baby potatoes halved
2 cups green beans trimmed
3 tablespoons olive oil
2 cloves garlic minced
Salt and pepper to taste
1 teaspoon dried Italian herbs optional

Step by Step Instructions

Preheat the oven to 400°F (200°C).
In a bowl mix the olive oil minced garlic salt pepper and Italian herbs.
Toss the baby potatoes and green beans in the olive oil mixture and spread them on a large sheet pan.
Pat the chicken breasts dry season with salt and pepper then coat the tops with grated Parmesan cheese.
Place the chicken on the sheet pan alongside the vegetables.
Bake for 25-30 minutes or until the chicken is cooked through and the vegetables are golden and tender.
Serve warm and enjoy!

Common Mistakes to Avoid

Thinking you do not need to preheat the oven rookie mistake. Roasting needs heat from the start or you get limp sad veggies.
Skipping the pat dry step. If the chicken stays wet the Parmesan will not adhere and you will miss that glorious crust.
Crowding the pan. If everything is piled up things steam instead of roast. If your sheet pan looks like a small city you might need a backup.
Overbaking the chicken. Use a meat thermometer if you have one. Aim for 165°F and then let the chicken rest a couple of minutes.
Using low quality Parmesan. Please do not use the powder in a shaker here. Freshly grated Parmesan makes a huge difference

Alternatives & Substitutions

Want to swap things out No big deal

Chicken thighs work great if you prefer dark meat. They will be juicier and you may need a couple more minutes of baking.
Use sweet potatoes instead of baby potatoes for a sweeter vibe. Cut them a bit smaller so they cook evenly.
Swap green beans for broccoli or Brussels sprouts if you like things a little more roasted and charred.
No Parmesan on hand Try Pecorino Romano for a sharper flavor or use a mix of Parmesan and breadcrumbs for extra crunch.
Prefer garlic powder over fresh garlic That is fine but fresh garlic gives a brighter punch so I recommend it when you can
Want lower oil Use a cooking spray on the vegetables and brush the chicken lightly so you do not lose flavor but save a bit on oil

IMO the easiest swaps are chicken thighs or broccoli. Those keep the same sheet pan energy without drama
