| Step | Do | Why |
|---|---|---|
| Soak | Hot soapy water, 15–30 min (or overnight) | Softens baked-on food so it lifts off |
| Scrub | Non-scratch pad or wooden scraper, no metal | Protects the ceramic or glass glaze |
| Stubborn | Baking-soda paste, sit an hour, then scrub | Gently lifts burnt-on residue |
| Careful | Let the dish cool before adding water | Cold water on a hot dish can crack it |
How to Clean a Gratin Dish
Published: ·Updated:
Let a baked-on gratin or casserole dish soak in hot, soapy water for at least fifteen minutes, then lift off the softened food with a non-scratch scrubber or a wooden scraper. For stubborn burnt-on spots, spread a paste of baking soda and water, leave it an hour, then scrub — and never pour cold water into a hot dish, which can crack it.
