Choose russet potatoes for the best texture and flavor. Don’t overfill the potato skins to avoid spilling during baking. For extra crispy edges, broil the casserole for 2-3 minutes at the end, watching carefully to prevent burning. Vegan versions can use olive oil, dairy-free cheese, and plant-based yogurt. Store leftovers in an airtight container in the fridge for up to 3 days and reheat in the oven. You can also freeze the filled potato shells before baking and bake straight from frozen, adding extra time as needed.
