A Purple Pig favorite, brought home: lemon-and-oregano chicken thighs off the grill, crackly fried smashed potatoes, and a cool, garlicky tzatziki to pull it all together.
Cook the thighs all the way to 175°F. Dark meat is the opposite of a chicken breast — it's best well-done, not just barely safe. Around 175°F the connective tissue melts into gelatin and the meat turns silky and juicy; pull it at 165°F and it can still be chewy. An instant-read thermometer (see the Tool Drawer) takes the guessing out of it. More on why in Kitchen Notes.
Why thighs, not breasts. Thighs stay moist on a hot grill where breasts dry out, they take a marinade beautifully, and they're cheaper. This is the cut The Purple Pig built the dish around, and it's the right call at home too.
Yukon Golds are the potato to use. They're the middle-ground potato — creamy enough to go fluffy inside, waxy enough to hold together when you smash them, with a thin skin that crisps. Russets fall apart; see the potato note in Kitchen Notes.
Everything but the frying can be done ahead. Marinate the chicken and make the tzatziki the night before; boil and smash the potatoes earlier in the day and leave them on the sheet pan. Then it's just grill and fry when people are hungry.
Squeeze the cucumber like you mean it. Watery cucumber makes runny tzatziki. After grating, wring it out in a towel until it stops dripping — you'll be surprised how much comes out.
Provenance: inspired by the Chicken Thigh Kebabs with fried smashed potatoes and house-made tzatziki that Chef Jimmy Bannos Jr. serves at The Purple Pig in Chicago. This is a home cook's version written from the components and technique, not the restaurant's recipe.
Store-bought tzatziki is the real time-saver here — a squeeze of fresh lemon and a little grated garlic stirred in make it taste homemade.
Cook the thighs to 175°F. Dark meat wants to be fully cooked; at 175°F it's silky and juicy, not chewy.
Gluten-free: nothing to change — the marinade, potatoes, and tzatziki are all naturally gluten-free.
Dairy-free: the only dairy is the tzatziki. A thick unsweetened coconut or cashew yogurt (Cocojune, Forager) makes a good stand-in — grate in the cucumber and garlic the same way.
Meatless: the same marinade and plate work beautifully with halloumi (cut into thick cubes, skewered, grilled until it takes color) or with big mushroom and zucchini chunks. It's a different dish, but the potatoes and tzatziki carry it.
