Ingredients
  

  • 3.5 pounds (1.5kg) about 10 small-medium russet potatoes
  • 1 onion, finely chopped
  • 2 tablespoons olive oil
  • 2 eggs, lightly beaten
  • 7-9 ounces (200-250g) graviera cheese or a combo of mozzarella-edam-gouda, grated*1
  • 2 tablespoons mint, finely chopped
  • ½ cup parsley, finely chopped
  • ½ cup (120)ml milk
  • 5 tablespoons breadcrumbs
  • 2 tablespoons olive oil for topping
  • Salt and freshly ground pepper, to taste

Instructions
 

PREPARE THE POTATOES

  • Wash the potatoes and place them whole, skin-on, in a pot. Cover with cold water, add 1 tablespoon of salt, and bring to a boil. Cook for 20 minutes (longer for larger potatoes), or until easily pierced with a fork.
  • Rinse with cold water until cool enough to handle. Drain well. Twist the potatoes to remove the skin effortlessly.
  • Mash them using a potato masher, a food mill, or a fork (don’t use a food processor). Season with salt and pepper to taste.
  • Preheat the oven to 400°F (200°C).

PREPARE THE ONION

  • Meanwhile, in a small skillet on medium to high heat, add the onion and sauté until softened about 5 minutes. Remove from heat and let it cool.

ASSEMBLE THE INGREDIENTS

  • In a large mixing bowl, combine the mashed potatoes with the onion, the eggs, the mint and parsley, the grated cheese, and the milk. Use a fork or a spatula to mix well until fully incorporated.
  • Season with salt and pepper but be careful because the cheese adds a lot of saltiness.

PREPARE THE BAKING DISH

  • Grease a baking dish with olive oil (I used a 7x10inch/18x25cm baking dish)*2. Pour the potato mixture into the dish, smoothing the top with a spatula.
  • Drizzle the surface with olive oil and sprinkle evenly the breadcrumbs. Use a knife to lightly score the surface into pieces for easier serving.

BAKE

  • Place the baking dish on the middle rack of the oven and bake for about 50 minutes, or until the top is golden brown.
  • Remove from the oven and let cool for about 30 minutes. Serve hot or cold.

Notes

  1. For extra cheesy flavor, you can go up to 300-350 grams (10-12 ounces) of cheese. More cheese combos you can use: a) Cheddar and mozzarella b) Cheddar, Gruyère, and Parmesan.
  2. You can use a variety of baking dish sizes, from a smaller but deep 8x8 inch (20x20 cm) dish to a larger 10x10 inch (25x25 cm) dish, and all the sizes in between. The larger the baking dish, the thinner your Greek potato soufflé will be.
