Grandma’s Tips for the Best Au Gratin Potatoes
Getting those perfectly tender layers and a bubbly, golden top comes down to a few time-tested tricks Grandma always used in her kitchen:
- Slice Potatoes Evenly: Use a mandolin or a sharp chef’s knife to slice your potatoes into uniform 1/8-inch rounds, unless using the shredded potatoes. As a result, even slices ensure every potato cooks through at the exact same rate so you don’t end up with crunchy spots!
- Don’t Rinse the Potato Slices: The natural starches in the potatoes help thicken the rich cream sauce as it bakes. This makes it extra silky without needing heavy thickeners.
- Shred Your Own Cheese: Pre-shredded bagged cheese is coated in anti-caking cellulose, which can prevent it from melting smoothly. Shredding your cheese fresh off the block gives you that luscious, gooey stretch!
- Let It Rest Before Serving: Resist the urge to dive in immediately! Allow the casserole to sit for 10 to 15 minutes after pulling it out of the oven. This helps the cream sauce set up so you can scoop out neat, beautiful portions.
