Cast iron cookware has long been heralded as a kitchen staple for its unparalleled heat retention, durability, and ability to naturally enhance flavors over time. Among the most versatile pieces in this collection is the cast iron griddle. Whether you’re flipping pancakes, searing steaks, or roasting vegetables, a well-cured griddle can make all the difference. In this comprehensive guide, we will explore how to cure your cast iron griddle, ensuring it remains a reliable cooking companion for years to come.
Understanding the Importance of Curing Cast Iron
Before diving into the curing process, it’s essential to understand why curing is crucial for cast iron cookware. Curing, also known as seasoning, involves applying a layer of oil to the surface of the cast iron and heating it to create a protective, non-stick coating. This process provides several benefits:
- Enhanced Non-Stick Surface: A well-cured surface allows for easier cooking and cleanup, making it less likely that food will stick.
- Rust Prevention: Curing protects the iron from moisture and air, which can lead to rust formation.
- Flavor Enhancement: Over time, seasoning builds up, adding depth and richness to the dishes prepared.
Understanding these benefits illustrates why regular maintenance of your cast iron griddle is vital for preserving its integrity and functionality.

Step-by-Step Guide to Curing Your Cast Iron Griddle
With your supplies at hand, we can move on to the process of curing your cast iron griddle. This method may take a little time, but the results will be worth the effort.
Step 1: Cleaning Your Griddle
The first step in the curing process is to ensure your griddle is thoroughly cleaned:
Removing Old Seasoning
If your griddle has existing layers of seasoning, you may need to strip back to the bare metal. Here’s how:
- Rinse the griddle under hot water to loosen stuck-on food.
- Use a cast iron brush or scrubber to scrub away any residue, rust, or chipped old seasoning.
- For stubborn spots, a mixture of coarse salt and some hot water can help create an abrasive scrub that won’t damage the cast iron.
- Rinse and dry the griddle completely. Never leave it wet, as moisture can lead to rust.
Step 2: Applying Oil
Once your griddle is clean and dry, it’s time to apply the oil. This step is critical, as the oil forms the base of the seasoning layer:
- Choose a neutral oil with a high smoke point (like flaxseed oil, grapeseed oil, or vegetable oil).
- Pour a small amount of oil onto the griddle surface—about a tablespoon should suffice.
- Using paper towels, spread the oil evenly across the entire cooking surface, including the sides. The goal is to create a thin, even layer; too much oil can lead to a sticky residue.
- Wipe away any excess oil to ensure that you only have a very light coat remaining.
Step 3: Heating the Griddle
Now that your griddle is coated with oil, it’s time to heat it to cure the seasoning:
Using an Oven
- Preheat your oven to 450°F (232°C).
- Place a baking sheet or a piece of aluminum foil on the bottom rack to catch any drips.
- Place the griddle upside down on the middle rack of the oven. This prevents oil from pooling in the cooking surface.
- Let it bake for an hour. This step polymerizes the oil, chemically bonding it to the iron.
- After an hour, turn off the oven and allow the griddle to cool inside. This slow cooling period will help prevent cracking.
Using a Grill
If the weather permits, you can also cure your griddle using an outdoor grill:
- Preheat the grill to a similar temperature (around 450°F or 232°C).
- Place the griddle upside down on the grill grates.
- Close the lid and let it cure for an hour.
- After an hour, turn off the grill, and let the griddle cool inside before removing.
Step 4: Repeat for Optimal Results
For improved seasoning, repeat the oil application and heating process 2-3 times. Each layer will help create a stronger and more effective non-stick surface, ensuring your griddle performs at its best.
Maintaining Your Cured Cast Iron Griddle
Once you’ve successfully cured your cast iron griddle, taking proper care of it will help prolong its life and functionality.
Cleaning Recommendations
After each use, clean your griddle with hot water and a cast iron brush or scrubber. Avoid using soap, as it can strip away the seasoning. For stuck-on food, you can use a small amount of coarse salt to scrub gently. Rinse and dry the griddle thoroughly to prevent rust.
Re-seasoning Tips
Over time, you may need to re-season your griddle to maintain its non-stick properties. This can be done by following the steps outlined above. Pay attention to any areas that may show signs of wear or rust; these spots can be sanded lightly before re-seasoning.
Common Mistakes to Avoid
While curing your cast iron griddle is a fairly straightforward process, there are common mistakes that can hinder its longevity and performance:
Over-Oiling
Applying too much oil can lead to a sticky surface rather than a smooth, seasoned one. Always remember, a light coat is sufficient.
Neglecting to Dry Completely
Leaving your griddle wet can invite rust. Always ensure it dries entirely after each cleaning.

What is the best way to clean a rusted cast iron griddle?
To effectively clean a rusted cast iron griddle, start by removing any loose rust with a stiff brush or steel wool. Make sure to scrub gently to avoid damaging the cast iron surface. After you’ve removed the rust, wash the griddle with warm water and mild dish soap. This is one of the few times soap is acceptable, as you’ll be seasoning it afterward. Rinse it thoroughly and dry it completely with a lint-free towel.
Once the griddle is dry, apply a thin layer of oil, such as flaxseed or vegetable oil, over the entire surface. Place it upside down on the oven’s middle rack, and add a sheet of aluminum foil on the lower rack to catch any drips. Preheat the oven to 500°F (260°C) and let it bake for an hour. This process will help restore its seasoning while preventing further rust.
How often should I season my cast iron griddle?
The frequency of seasoning a cast iron griddle can vary depending on how often you use it. Generally, it’s recommended to season your griddle after every few uses, especially if you notice food sticking or if the surface appears dull. A well-seasoned griddle will have a smooth, non-stick surface, and regular seasoning will maintain its performance and extend its lifespan.
In addition to regular seasoning, you should also clean your griddle properly after each use. Avoid soaking it in water and instead wipe it down with a damp cloth. If you cook acidic foods, you may need to season it more often, as acids can strip away the seasoning. Keeping an eye on the condition of your griddle will help you determine when it needs a fresh layer of seasoning.
Can I use soap on my cast iron griddle?
Using soap on a cast iron griddle is generally discouraged, as it can strip away the seasoning that has built up over time. However, if your griddle is heavily soiled or has developed rust, a mild detergent can be used sparingly to help with the cleaning process. Just make sure to thoroughly rinse the griddle afterward and dry it completely to prevent any moisture from causing rust.
After cleaning, it’s important to reapply a thin layer of oil to re-season the griddle and maintain its non-stick properties. Future cleanings can typically be done with warm water and a stiff brush or sponge to remove residue, allowing you to keep the seasoning intact. Following this approach will help you retain the non-stick surface and prevent rusting.
What oil is best for seasoning a cast iron griddle?
Flaxseed oil is widely regarded as one of the best oils for seasoning cast iron griddles due to its high smoke point and ability to create a hard, durable layer of seasoning. Other suitable oils include grapeseed oil, canola oil, and vegetable oil. These oils can withstand the high temperatures required for seasoning and can help create a smooth, non-stick surface.
When seasoning, it’s important to apply the oil in a thin, even layer. Using too much oil can result in a sticky surface, while too little may not effectively create a protective coating. Allow the griddle to bake upside down in the oven, which ensures that any excess oil drips off, leaving a properly seasoned surface.
What should I do if my cast iron griddle is still sticky after seasoning?
If your cast iron griddle remains sticky after seasoning, it likely means that too much oil was applied during the process. To remedy this, you can re-scrub the griddle to remove the excess seasoning. Use steel wool or a stiff brush and wash it with mild soap and water. Dry it thoroughly and then re-season the griddle using a very light layer of oil to prevent stickiness.
When re-seasoning, make sure to bake it at high temperatures for a longer period, typically around an hour, to allow the oil to polymerize and bond with the cast iron. This should help create a smoother surface. In the future, ensure that you’re applying only a thin layer of oil after cleaning to avoid the stickiness issue and maintain a well-seasoned griddle.
Can I use metal utensils on my cast iron griddle?
Yes, you can use metal utensils on your cast iron griddle without worrying about damaging it. One of the benefits of cast iron cookware is its durability, which allows it to withstand the use of metal spatulas, tongs, and other utensils.
