Start by preheating the oven to 425°F. Grease a baking dish and set it aside.
In a food processor, combine the feta, labne, lemon zest, and 2 tablespoons of water. Blend until smooth. For a thinner texture, add 2 tablespoons of water at a time, pulsing until you reach the desired consistency. Set aside.
Place the red potatoes in a single layer on the prepared baking dish. Drizzle olive oil, garlic, salt, pepper, and lemon zest on top. Toss everything together.
Bake for 20-25 minutes or until the potatoes are tender, flipping them halfway through.
Spread the whipped feta mixture on a platter and arrange the potatoes on top. Garnish with crushed red pepper, parsley, and an optional drizzle of extra olive oil.
You can store the potatoes and whipped feta in separate airtight containers in the fridge for up to 3 days. Enjoy your flavorful Greek Potatoes with Whipped Feta!
