Grill expander Kamado Joe Grill Expander for round 18-inch charcoal grills, silver, compatible with Joe Classic/Big Green Egg

The Kamado Joe Grill Expander for round 18-inch charcoal grills is a single-piece silver accessory designed to increase usable cooking surface on compatible kamado-style grills. Compatible with the Joe Classic series, Large Big Green Egg and other round 18" charcoal grills, the expander sits directly atop the existing cooking grate, providing additional room for food or accessories and creating clearance for indirect heat cooking, smoking and gentler grilling.

Advantages

The Grill Expander adds up to 60 percent more cooking surface by elevating an additional surface above the main grate and provides roughly four inches of clearance beneath the raised surface. Made to sit securely on the grill with slotted feet for stability, the expander is dishwasher-safe for easier cleaning and allows flexible arrangement of different surfaces to suit varied cooking tasks.

Suitable for

• Grilling additional items when main grate space is limited
• Smoking or indirect heat cooking that requires elevation from direct flame
• Cooking delicate foods like vegetables and thin cuts away from direct fire
• Using accessories or arranging mixed cooking surfaces on 18-inch round grills

Key specifications

• Compatibility: round 18-inch kamado-style charcoal grills including Joe Classic series and Large Big Green Egg
• Material and finish: silver finish (single-piece construction)
• Mounting: sits directly on existing grill grate with slotted feet for stability
• Clearance: approximately four inches of elevation above the main grate
• Cleaning: dishwasher-safe
• Effect on cooking area: increases usable cooking surface by up to 60 percent

How to use

Place the Grill Expander directly on top of the existing cooking grate so the slotted feet rest evenly for stable positioning. Use the additional raised surface to hold more food, to separate delicate items from direct flame, or to position accessories for indirect cooking. The elevation creates a gap that moderates heat exposure for smoking and low-and-slow techniques. After use, follow your grill manufacturer’s cooling recommendations before removing the expander and clean it according to material guidelines; it is dishwasher-safe for convenient maintenance.

Usage recommendations

Check fit and stability before heating: ensure the expander sits level on the grate and does not interfere with grill lid closure. When cooking at high temperatures, monitor accessory positioning and food placement to avoid flare-ups. Allow the expander to cool before cleaning or storing.
