1. Prepare the ingredients
2. Steam the potatoes, peel them, put them in a fresh-keeping bag, and crush them with a rolling pin.
3. Put the crushed potato mash into the container, add milk little by little, grind the potatoes thoroughly to form a thick paste, add a little salt to taste.
4. Pour a little olive oil and butter into the wok, add chopped onions and fry them for a fragrance, and then add a little black pepper.
5. Pour the fried onions into the mashed potatoes and mix well.
6. Put the mixed potato mash into a heat-resistant container, sprinkle with cheese (I also put a small amount of sausage), put it in the oven, 150 degrees, 20 minutes.
Tips:In the crushed potatoes, add milk little by little, and mix well. There should be no potato particles, or the taste is not good. When frying chopped onions, keep the heat on a low heat to avoid frying.
