Preheat on medium, never high — enameled cast iron holds heat so well that high heat scorches the outside while the inside stays underdone, and thermal shock is what actually cracks the enamel.
Why heat control matters more than heat level
Cast iron's biggest strength — how evenly and stubbornly it holds heat — is also what trips people up. Most home cooks treat it like a thin stainless pan and crank the burner to high, expecting quick response. Enameled cast iron doesn't work that way: it heats slowly, holds that heat long after you've turned the burner down, and punishes sudden temperature swings by stressing the enamel coating.
The correct searing technique
- Preheat on medium for a few minutes before adding fat. Rushing this with high heat is the top cause of scorched food and cracked enamel from thermal shock.
- Pat proteins fully dry before searing. Moisture on the surface steams instead of sears, and steam doesn't build the browned crust that gives braises their depth.
- Don't crowd the pot. Searing in batches keeps the pan hot enough to actually brown food instead of steaming it.
- Deglaze with liquid off the heat, not on it. Adding cold liquid to a screaming-hot empty pot is exactly the thermal shock that damages enamel over time.

Once the sear is done and aromatics are softened, bring the liquid to a simmer on the stovetop, then move the whole pot into a low oven (around 300–325°F) rather than leaving it on a stovetop burner. Oven heat surrounds the pot evenly; stovetop heat concentrates on the bottom and risks scorching over a multi-hour braise.
- Preheating on high heat. Uneven heating and enamel stress — always start medium.
- Adding cold liquid to a very hot, empty pot. The temperature swing is the leading cause of enamel cracking.
- Using metal utensils that scrape hard against the enamel. Wood or silicone protects the interior coating.
- Soaking or scrubbing with abrasive pads. A soft sponge and hot water handles the vast majority of stuck-on food; let stubborn spots soak instead of scrubbing hard.
- Storing with the lid sealed tight while still slightly damp. Air it out fully first to avoid musty smells building up.
Caring for the enamel long-term
Let the pot cool before washing — never plunge a hot pot into cold water. Hand-washing is gentler on the enamel than a dishwasher, even on pots labeled dishwasher-safe. Minor staining inside is cosmetic, not a defect, and doesn't affect cooking performance; a paste of baking soda and water lifts most of it if it bothers you.
