Instructions
Get your oven going to 425°F. While it’s heating up, dump your halved baby potatoes on the sheet pan with 2 Tbsp olive oil, salt, and pepper. Toss them around until they’re coated. This step is actually super important for getting crispy potatoes and I wish someone had emphasized that to me years ago when I was just throwing uncoated potatoes in the oven and wondering why they were sad and dry.
Okay so grab a bowl and throw in 2 Tbsp olive oil, your chicken, balsamic vinegar, Dijon mustard, oregano, paprika, chopped garlic, shallot, salt, pepper, and however much chili flakes you can handle. I go really light because I’m a wimp but my husband dumps in like a tablespoon because he’s insane. Just massage that marinade into the chicken with your hands—it’s messy and your hands will smell like garlic for the rest of the day but it’s worth it.
Now here’s where I used to mess up every time. Take those chicken pieces and nestle them in with the potatoes but don’t pack everything in super tight. Give them space. I know it’s tempting to make it all fit on one pan but trust me, if it’s too crowded you’ll end up steaming everything instead of roasting it and it’ll be sad. Use two pans if you need to. Stick it in the oven for 25–30 minutes. I usually start checking mine around 23 minutes because my oven runs hot and I’ve definitely overcooked chicken before (many times actually).
While everything’s baking you can make the herb situation. Mix together the remaining ⅓ cup olive oil, lemon juice, all those chopped herbs, pepperoncini, olives, and sesame seeds in a bowl. This is when your kitchen starts smelling incredible and you feel like maybe you actually know what you’re doing. That lemon juice keeps the herbs from turning brown and gross looking which is a nice bonus.
Just dump your tzatziki and crumbled feta in a small bowl and mix it up. Taste it—sometimes I add more lemon or crack some black pepper over it depending on what it needs. And then I usually eat a big spoonful because I have zero self-control around tzatziki. My kids think this is hilarious and also try to steal spoonfuls before dinner.
When your chicken and potatoes are done (check that the chicken hits 165°F internally—I finally bought a meat thermometer after serving undercooked chicken to guests one mortifying time), pull that pan out. Immediately spoon all that herb-olive mixture over everything while it’s still super hot. The heat makes all those herb oils release and the smell is just… chef’s kiss. Serve it with the feta-tzatziki sauce on the side or just dump it all over top. I usually do both because why not.
Notes
Don’t skip the step of halving your potatoes! Whole baby potatoes take much longer to cook and won’t get those crispy cut sides. If your chicken is done before the potatoes, remove the chicken and let the potatoes continue roasting.
Use a rimmed sheet pan to catch all those delicious juices—they’re gold for spooning over your finished dish. If you want extra crispy chicken skin (and you’re using skin-on pieces), broil for the last 2–3 minutes of cooking.
Common mistake to avoid: Overcrowding the pan. If things are too packed, you’ll get steaming instead of roasting. Use two pans if needed, or roast in batches.
Flavor Variations & Suggestions
Swap the green olives for Kalamata olives for a richer, more robust flavor. Add cherry tomatoes in the last 10 minutes of baking for a burst of sweetness. For a spicier kick, double the chili flakes or add sliced jalapeños to the herb mixture.
Try swapping baby potatoes for sweet potato chunks—they’ll add natural sweetness that pairs beautifully with the balsamic. You can also throw in vegetables like zucchini, bell peppers, or red onion wedges alongside the potatoes.
For a citrus twist, add orange zest to the marinade along with the lemon juice. Fresh mint in the herb mixture brings a completely different but equally delicious dimension.
