Many cast iron grill pans arrive pre-seasoned. Check the pan’s label or manual; if it is factory-seasoned, wash and dry it before use as directed. Oven seasoning is useful when the cooking surface looks dull or bare, or after you have removed rust or old seasoning. It is not a step you need to repeat after every meal.
What You Need
- Warm water and a small amount of dish soap
- A clean towel or lint-free cloth
- A neutral cooking oil or cast iron seasoning spray
- Aluminum foil to catch any drips
- Oven mitts
How to Season a Cast Iron Grill Pan in the Oven
- Check the care instructions. Confirm the pan is oven-safe and has no wood, plastic, or other parts that cannot tolerate oven heat. Follow the pan maker’s directions if they specify a different temperature or method.
- Wash the pan. Use warm, soapy water and a brush to remove food residue, dust, or loose flakes. If the pan has rust, remove the rust first rather than sealing it under oil. Lodge’s rust-restoration guide explains that separate process.
- Dry it completely. Towel-dry the pan, including the channels between the ridges. You can place it over low stovetop heat for a few minutes to evaporate moisture. Use oven mitts—the pan may already be hot.
- Apply a very thin coat of oil. Spread a little cooking oil over the cooking surface, underside, sides, and handle. Then wipe again with a clean cloth until the pan looks almost dry. Pooled oil can leave a sticky finish.
- Bake the pan upside down. Heat the oven to 450–500°F, or to the temperature specified by your pan’s maker. Put foil on a lower rack to catch drips; set the pan upside down on the center rack. Bake for one hour.
- Let it cool in the oven. Turn off the oven and leave the pan inside until fully cool. Use mitts when handling it, even after the oven is switched off.
These oven-seasoning steps follow Lodge’s current cast iron instructions. The method applies to many one-piece cast iron grill pans, but individual care directions take priority.
Which Oil Should You Use?
A plain cooking oil works; use the oil recommended by the cookware maker and apply only a thin film. A dedicated spray can make it easier to spread a light coat. Lodge Seasoning Spray is one option. It is not required—regular cooking oil is enough when applied sparingly. For a comparison of cast iron care oils, see our cast iron seasoning oil guide.

How to Maintain the Seasoning
After cooking, wash the pan with warm water and a brush; a little dish soap is fine. Dry it promptly and completely, then wipe on a barely visible layer of cooking oil if the surface looks dry. Regular cooking with a little fat also builds seasoning over time. Routine cleanup does not require an hour-long oven cycle.
Fixing Common Problems
Why is the pan sticky after seasoning?
Sticky spots usually mean too much oil remained or the oil did not bake long enough. Let the pan cool, wipe away any excess, and follow the maker’s troubleshooting steps. Lodge’s troubleshooting guide recommends baking its sticky cookware for another hour, or until the stickiness is gone.
What if the grill pan looks patchy?
Small variations in color are common and do not necessarily mean the pan has failed. Keep it clean and dry, use it with cooking fat, and let seasoning build gradually. Re-season if bare iron or rust is exposed.
How often should I season a cast iron grill pan?
There is no fixed schedule. Use and ordinary care build the coating. Oven-season when the surface is bare, badly worn, or has just been restored; otherwise, wash, dry, and lightly oil as needed.
