Slice potatoes into quarters and place in a large zip-lock bag with crushed rice crackers. Shake until potatoes are coated in the cracker crumbs.
Arrange potatoes on 2 large baking trays, drizzle with oil and bake for 25 minutes or until potatoes are golden, crispy and cooked through. Serve immediately.
Notes
Make ahead tip: Peel and slice potatoes a day in advance. Place in a bowl and cover with water. Store in the refrigerator. Drain and pat dry with paper towel before coating with rice crackers and baking.
