Benefits of Cast Iron Cooking Grates

There are countless benefits to using cast iron cooking grates on your grill. Here are just a few:

Even heat distribution

Cast iron is known for its ability to hold and distribute heat evenly. This means that your food will cook more consistently, without any hot or cold spots on the grill.

Beautiful sear marks

One of the reasons cast iron grates are so popular is because they create those classic criss-cross grill marks on your food. These not only add a visually appealing touch to your meals, but they also help with even cooking.

Durable and long-lasting

Cast iron is a highly durable material that can withstand high heat and frequent use. With proper care, cast iron cooking grates can last for many years, making them a wise investment for anyone who loves to grill.

Adds a smoky flavor

Due to the porous nature of cast iron, it absorbs and retains flavors from previous grilling sessions. This means that every time you use your cast iron cooking grate, you’ll get a delicious smoky flavor infused into your food.

Maintenance Tips for Cast Iron Cooking Grates

Taking care of your cast iron cooking grate is essential to ensure its longevity and optimal performance. Here are some tips to keep in mind:

Season your grates

Before using your cast iron cooking grate for the first time, it’s essential to season it. This involves heating up the grate and then rubbing a thin layer of vegetable oil or flaxseed oil onto its surface. This will create a non-stick coating and help prevent rust.

Clean after each use

After using your cast iron cooking grate, it’s important to clean it thoroughly. Use a grill brush or scraper to remove any food bits or debris, and then rinse with warm water. Avoid using soap as it can strip away the seasoning on the grates.

Dry thoroughly

Make sure to dry your cast iron cooking grate completely after cleaning. Leaving it wet can cause rusting and lead to a shorter lifespan.

Store properly

When not in use, store your cast iron cooking grate in a dry place. If storing it outdoors, make sure to cover it with a grill cover or other protective material.

How to Season Cast Iron Grates for Cooking

Seasoning your cast iron cooking grate is crucial for its performance and longevity. Here’s how to properly season your grate:

Preheat the grill

First, preheat your grill to a high temperature. This will help open up the pores of the cast iron and allow the oil to penetrate.

Apply oil

Using a paper towel or brush, apply a thin layer of vegetable oil or flaxseed oil onto the surface of the grate. Make sure to cover all areas evenly.

Heat for 20-30 minutes

Next, place the grate on the grill and let it heat for 20-30 minutes. This will help create a non-stick surface and prevent rust.

Repeat as needed

If your cast iron cooking grate starts to lose its seasoning, simply repeat the seasoning process. Regularly seasoning your grate will help maintain its performance and prolong its lifespan.

Comparison: Cast Iron vs. Stainless Steel Grates

Both cast iron and stainless steel are popular materials for grilling grates. Here’s a comparison of the two:

Heat retention

Cast iron has excellent heat retention, meaning it can hold and distribute heat evenly. Stainless steel does not retain heat as well.


While both materials are durable, cast iron is more prone to rusting if not properly cared for. Stainless steel is less likely to rust and can withstand high temperatures.


Cast iron requires regular seasoning and more careful cleaning, while stainless steel is easier to maintain and clean.

Cooking performance

Many chefs prefer using cast iron grates because they give food a better sear and add flavor. However, stainless steel grates are also great for cooking as they don’t impart any additional flavors.


Stainless steel grates tend to be more expensive than cast iron ones. However, they also have a longer lifespan and require less maintenance, making them a better long-term investment.

Best Practices for Cooking on Cast Iron Grates

Here are some tips for getting the best results when cooking on a cast iron grate:

  • Preheat your grill and let the grate heat up before adding food.
  • Oil your food, not the grate. This will help prevent sticking.
  • Don’t overcrowd the grill. Leave enough space between food for air to circulate and allow for even cooking.
  • Don’t move the food around too much. Let it sit and form a crust before flipping.
  • Use a grill brush to clean off any leftover bits of food after cooking.
  • After cleaning, rub some oil on the grate to prevent rusting.


To sum it up, both cast iron and stainless steel grates have their own advantages and disadvantages. Cast iron is great for its heat retention and cooking performance, but requires more maintenance. Stainless steel is easier to maintain and more durable, but may not provide the same flavor when cooking. Ultimately, the best choice will depend on personal preference and cooking needs. Whichever type of grate you choose, following best practices for cooking and maintenance will help ensure delicious results every time.  So the next time you fire up your grill, consider these factors when choosing between cast iron and stainless steel grates.
