Make Ahead Tip: Prepare through Step 6; cover and refrigerate for up to 1 day or freeze for up to 1 month (defrost in the refrigerator for 2 days before baking). Let stand at room temperature for 30 minutes before baking (Step 7).
Note: Precooked shredded potatoes can be found in the dairy section of most supermarkets or near other fresh prepared vegetables in the refrigerated produce section. To make your own, halve 1 pound unpeeled baking potatoes; cook in lightly salted boiling water until slightly tender but still firm in the center, 7 to 10 minutes. Let cool on a clean cutting board. Shred using the large holes of a box grater.
Storage smarts: For long-term freezer storage, wrap your food in a layer of plastic wrap followed by a layer of foil. The plastic will help prevent freezer burn while the foil will help keep off-odors from seeping into the food.
