Globally, home cooks frequently attempt to turn a humble sack of potatoes into a hearty evening meal. In my cooking adventures often involve a aromatic Sri Lankan potato curry, a flavorful Gujarati version, or even a slow-cooked Spanish tortilla for a special occasion. On this occasion, however, the answer comes from Greece. Yahni describes a classic Greek preparation technique: produce slow-cooked amply in olive oil and tomatoes until deliciously soft. It’s as much a philosophy—it’s a celebration of the simple, the patient, and the truly delicious (and yes, it also makes a superb dinner).
Enjoy this with warm bread or Greek pitas for a hearty meal. It also pairs beautifully with a assortment of picky bits or even served alongside a fried egg for a unexpectedly great breakfast.
Prep Time: 10 minutes
Cook Time: 1 hour
Serves: 4 people
Pour five tablespoons of olive oil in a capacious casserole dish that has a fitting lid. Set it over a moderately high heat. Once the oil is heated, add the onion slices and a teaspoon of salt. Sauté, moving it around, for about 10 minutes, until the onion is translucent enough to be cut a wooden spoon.
Introduce the minced garlic and cook for a further two minutes, stirring constantly. Then, toss in the potato wedges and oregano, tossing until they are evenly covered in the oil. Mix in the tomato puree and cook for one minute. Pour in the chopped tomatoes along with 400ml of water. Let it come to a boil, then put the lid on, turn down the heat to a gentle simmer, and leave to cook for 20 minutes.
Meanwhile, make the whipped feta. In a small bowl with a hand blender, blitz the feta, Greek yoghurt, lemon zest and juice, three tablespoons of olive oil, and a big pinch or two of salt until the mixture is completely smooth.
Stir the pitted kalamata olives into the potato stew. Let it cook without the lid for a further 15-20 minutes, until the potatoes are completely soft and the sauce has become beautifully cohesive.
Spoon the warm yahni into serving dishes. Top each with a generous spoonful of the whipped feta and a scattering of dried oregano.
This dish is a testament to the beauty of few components turned into something special by patient cooking. Savor!
