- Overbaking the Dish: Keep an eye on your gratin while it bakes. Overbaking can lead to a burnt top, ruining the creamy goodness underneath.
- Skipping the Cheese Grating Step: Pre-shredded cheese contains anti-caking agents that affect melting. Always grate your cheese fresh for the best results.
