Seasoning Your Cast Iron Grill Grates

The first rule about Spark Club is: You season your grates before you cook on your new charcoal grill. 


No, but seriously.  Your Spark comes with heavy-duty, porcelain enameled, cast iron cooking grates. We’re obsessed with cast iron for our grill grates because it’s super durable and holds heat really well for that perfect sear. Cast iron grill grates require more maintenance than regular steel grates, but the cooking results and durability make the extra effort entirely worth it.


We know you can’t wait to start cooking on your Spark. But, before you throw down, we recommend firing up the grill to season the grates first. 


Why Season Your Cast Iron Grill Grates?

Seasoning creates a non-stick coating on the cooking surface that helps you achieve the perfect sear, while protecting the grill’s grates from wear and rust. We threw in a special Seasoning Briq with your order for you to use during the first seasoning burn. 


How to Season Your Spark Grill Grates

  1. Start by rinsing the grates off with warm water, then wipe them dry with a towel. Next, use either an oil mister, brush, or paper towel/rag to thoroughly coat the grates on both sides with a high smoke point oil. We recommend canola, peanut, or flaxseed oil. 
  2. Once the grates are coated, return them to the grill. Load up the Seasoning Briq into the drawer and turn the ignition ring to the light position for 3 seconds to start the grill. Set the temperature knob to 350F degrees and shut the lid for 15 minutes.
  3. After 15 minutes, open the lid and use a pair of tongs to hold a rag or paper towel coated in oil. Gently wipe the grates from back to front until the topside is again fully coated in oil. Be careful to shake off the excess oil before wiping, since the drips can cause flare ups. Shut the lid.
  4. Turn the temperature up to 450F for 20 minutes.
  5. After 20 minutes, turn the ignition switch to the left “off” position. Leave the grill plugged in for two hours, so the fans can work to cool it down completely. 
  6. Once the grill is completely cool, dispose of the used Seasoning Briq into a charcoal or ash can with a lid. 


Your grates are now properly seasoned and ready for your favorite grilled pork tenderloin. Or maybe grilled mahi mahi with grilled carrots tonight. Or Beyond elote burgers.

Your Spark can do it all - that’s the beauty of the precision temperature control. 


We hope you cook new things. Cook with confidence. Cook outside. And cook more often.
