Heat oven to 390F. Oil a baking pan (the one used here was 12 inches in diameter), and place in the oven to warm up. (This will prevent the stickiness. If it starts to smoke up while you're preparing the ingredients, take the pan out, and add a little more oil.)

Peel and grate the potatoes and onions and place into a bigger bowl. Mince bacon and add to the bowl with the rest of the ingredients. Combine and mix well. Carefully transfer the mass into the hot and oiled baking pan, and even it out so it's the same thickness everywhere.

Bake for 20 minutes at 390F turning the pan around about halfway. Then lower the temperature to 360F and bake for another 10 minutes. (Total baking time is 30 min.)

Take out, and spray with water lightly. Leave to cool a little bit, then break into parts with your hands. If you like, soak in milk, buttermilk or yogurt, and add minced garlic.
