I started by preheating my oven to 425°F and lining a baking sheet with parchment paper. Then, I boiled the potatoes until they were fork-tender, making sure they didn’t overcook. Once drained, I transferred them to the baking sheet.
Next, I used the back of a glass to gently flatten each potato, leaving them chunky but broad. I brushed them with olive oil and sprinkled salt and pepper evenly. Roasting for 50–60 minutes gave them that irresistible golden, crispy exterior while keeping the inside soft.
While the potatoes roasted, I whipped together Greek yogurt, mayo, Dijon mustard, lemon juice, red wine vinegar, minced garlic, fresh dill, and parsley. I folded in the finely chopped cucumber and shallot, tasted, and adjusted seasoning. Letting it chill in the fridge helped the flavors meld beautifully.
Once the potatoes cooled slightly, I folded them gently into the dressing until fully coated. I saved a few crispy bits for garnish. Sprinkling extra dill and a dash of black pepper made it look as good as it tasted. Refrigerate any leftovers for later.
