Wash the spinach, boil it for 2 minutes in a pot of water, then drain it in a colander, pressing out as much water as possible. Sauté the crushed garlic and spinach in a skillet with a little oil. Season with salt and pepper. Peel the potatoes and cut them into cubes. Rinse well, season with salt, and fry them until golden.

Grease a baking dish. Spread the spinach as the first layer, then add the fried potatoes on top. For the cream mixture: whisk together the milk, eggs, diced processed cheese, and spices. Pour this cream mixture over the top and sprinkle with chopped parsley.

Bake in a preheated oven at 300°F (150°C) for about 20 to 25 minutes, or until the edges are golden brown. (Adjust baking time as needed for your oven.)
