Heat oven to 450º F. Brush 2 baking sheets with 1 tablespoon of the oil and set aside.
Using a box grater or a food processor fitted with a shredding blade, coarsely grate the potatoes. Place the grated potatoes in a large bowl with the onion, flour, salt, pepper, eggs, and the remaining tablespoon of oil. Toss to mix well.
Drop by rounded tablespoonfuls onto baking sheets and press lightly to make patties. Bake 10 minutes or until golden brown on the bottom. Turn the latkes with a metal spatula and rotate the baking sheets. Bake another 5 minutes or until golden. Transfer to a platter and serve with the applesauce and sour cream.
