4. Initial Setup and Seasoning
Your cast iron griddle/grill may come pre-seasoned, but additional seasoning is recommended for optimal performance and to build a durable non-stick surface. Follow these steps before first use:
- Wash and Dry: Thoroughly wash the griddle/grill with warm water and a mild soap. Use a stiff brush or sponge to remove any manufacturing residues. Rinse completely and dry immediately with a lint-free cloth.
- Apply Oil: Apply a thin, even layer of high smoke point cooking oil (such as vegetable oil, canola oil, or flaxseed oil) to all surfaces of the griddle/grill, including the handles. Use a paper towel to wipe off any excess oil, leaving only a very thin film.
- Heat: Place the griddle/grill in an oven preheated to 375-400°F (190-205°C) for one hour. Alternatively, place it on your stovetop over medium heat for 15-20 minutes until it begins to smoke lightly. Ensure good ventilation.
- Cool: Turn off the heat and allow the griddle/grill to cool completely.
- Repeat (Optional but Recommended): For a more robust seasoning, repeat the oil application and heating process 2-3 more times.
This initial seasoning process creates a protective layer that improves cooking performance and prevents rust.

5. Operating Instructions
The GE Reversible Cast Iron Griddle/Grill Combo offers two distinct cooking surfaces. Always preheat the griddle/grill gradually to ensure even heat distribution.
5.1 Using the Smooth Griddle Side
The smooth side is ideal for cooking delicate foods that require a flat, even surface. This includes:
- Scrambled eggs
- Pancakes
- Grilled cheese sandwiches
- Toast bread
- Tortillas
- Fajitas
- Vegetables
Instructions:
- Place the griddle/grill with the smooth side facing up on your stovetop grates.
- Preheat gradually over medium-low heat for 5-10 minutes.
- Add a small amount of cooking oil or butter before adding food, even if seasoned.
- Adjust heat as necessary for even cooking.
5.2 Using the Ribbed Grill Side
The ribbed side is designed to create sear marks and allow fats to drain, enhancing the flavor of grilled items. This side is suitable for:
- Meats (steaks, chicken, pork)
- Fish
- Poultry
- Hamburgers
Instructions:
- Place the griddle/grill with the ribbed side facing up on your stovetop grates.
- Preheat gradually over medium heat for 10-15 minutes. Cast iron heats quickly and evenly, maintaining a consistent temperature.
- Lightly oil the ribbed surface or the food itself before placing it on the grill.
- The high ridges help contain oil and provide safe gripping points.
- Adjust heat as necessary for desired searing and doneness.

6. Care and Maintenance
Proper care is crucial for maintaining your cast iron griddle/grill. Following these guidelines will prevent rust and preserve its seasoned surface.
- Cool Down: Allow the griddle/grill to cool completely before cleaning.
- Cleaning:
- Scrape off any food residue with a plastic scraper or stiff brush.
- Wash with hot water and a minimal amount of mild soap, if necessary. Avoid harsh detergents or abrasive scrubbers.
- Do not use a dishwasher. The griddle/grill is not dishwasher safe.
- For stubborn food, simmer a small amount of water in the griddle/grill for a few minutes, then scrape.
- Drying: Immediately after washing, thoroughly dry the griddle/grill. You can place it on a stovetop over low heat for a few minutes to ensure all moisture evaporates.
- Re-seasoning: After drying, apply a very thin layer of cooking oil to all surfaces. Wipe off any excess. This helps maintain the seasoning and prevents rust.
- Storage: Store the griddle/grill in a dry place. If stacking with other cookware, place a paper towel between items to prevent scratching and absorb any residual moisture.
Note: Washing with soap should be limited to 1-2 times per year, or when necessary to remove heavy grease. Frequent soap use can strip the seasoning. For most cleaning, hot water and a stiff brush are sufficient.
