Quick answer
For most cast iron cooking, preheat your pan over medium heat for 5-10 minutes. For searing steak, aim for a surface temperature of 450-500°F (230-260°C). For oven cooking, most recipes work well at 350-425°F (175-220°C). Always match the temperature to your recipe and avoid sudden temperature changes.
Why Cast Iron Needs Its Own Temperature Rules
Cast iron is dense and heats slowly, but once hot, it holds heat longer than aluminum or stainless steel. That means you can't treat it like a thin pan: cranking the burner to high immediately can cause uneven heating and hot spots. Instead, give the metal time to absorb heat gradually. This is especially important on glass-top stoves, where rapid temperature swings can stress the glass. The reward is a steady, even cooking surface that sears beautifully and moves from stovetop to oven without missing a beat.
Stovetop Heat Settings: What the Dial Really Means
Most electric and gas stoves don't display exact temperatures, so you'll need to learn your stove's personality. As a rule, low on a cast iron pan is around 250-300°F, medium is 350-400°F, and high can exceed 500°F. But these are estimates; every stove runs differently. Use an infrared thermometer to check the pan's surface temperature if you want precision. For most everyday cooking—eggs, pancakes, sautéed vegetables—medium is your friend. Reserve high heat for quick sears and stir-fries, and only after the pan is fully preheated.
Oven Temperatures for Cast Iron
Cast iron is oven-safe, but not all pieces are created equal. Bare cast iron can handle temperatures up to 500°F or higher, while enameled cast iron should generally stay below 450°F to protect the enamel. Check your manufacturer's guidelines. For baking cornbread, roasting chicken, or making a Dutch oven stew, 350-400°F is a reliable range. When switching from stovetop to oven, remember that the handle will be hot—use a mitt.
Step-by-Step Temperature Guide
- Preheat gradually: Place your cast iron pan on the stove over medium heat for 5-10 minutes. This allows the heat to spread evenly. A common mistake is skipping preheating or using high heat right away, which can cause hot spots and uneven cooking. Checkpoint: Sprinkle a few drops of water on the pan. If they sizzle and evaporate quickly, it's ready.
- Match heat to the task: Use medium heat (around 350-400°F) for eggs, pancakes, and sautéing. Use medium-high to high (450-500°F) for searing steak or stir-frying. For oven cooking, set the temperature according to your recipe, typically 350-425°F. Avoid sudden temperature changes, which can warp the pan. Checkpoint: Use an infrared thermometer to verify the surface temperature if you're unsure.
- Sear steak at the right temperature: For a perfect crust, preheat the pan until it's smoking lightly, around 450-500°F. Pat the steak dry, then place it in the pan. Don't move it for 2-3 minutes to develop a sear. A common mistake is crowding the pan or flipping too often, which steams the meat instead of searing it. Checkpoint: The steak should release easily when it's ready to flip.
- Bake and roast with confidence: Transfer the pan to a preheated oven. Most recipes call for 350-425°F. For enameled cast iron, keep the oven below 450°F to protect the finish. Remember that the pan is hot—use oven mitts. A common mistake is placing a cold pan into a hot oven; let it come to room temperature first if it's been in the fridge. Checkpoint: Use a timer and check doneness a few minutes early to avoid overcooking.
