Big Green EGG 12" Dual Zone Split Deflector (Half-Moon) Big Green EGG 12" Dual Zone Split Deflector (Half-Moon)

Flexible Indirect Cooking for Medium, Small & MiniMax Eggs

The Big Green Egg 12-inch Dual Zone Split Deflector creates direct and indirect cooking options using a half-moon ceramic heat barrier. Designed for the Medium Big Green Egg Dual Zone System, this deflector also works with select CGS Woo setups for the Small and MiniMax Eggs.

One Deflector for Two-Zone Cooking

Use one half-moon deflector to create an indirect cooking zone while leaving the opposite side open to the charcoal. The ceramic shields part of the cooking area from direct heat, allowing you to grill over the fire on one side and cook indirectly on the other.

Two Deflectors for Full Indirect Cooking

In compatible rack systems, two 12-inch half-moon deflectors provide broader heat protection beneath the cooking grid. This creates an indirect cooking setup for smoking, roasting, and low-and-slow barbeque.

Important: Deflectors are sold individually. The number of deflectors and required support system depend on your Egg size and cooking configuration.

Medium Big Green Egg – Dual Zone & CGS Woo Setups

The 12-inch half-moon deflectors are designed for the Medium Big Green Egg Dual Zone Basket. The basket supports the ceramic below the cooking grids, allowing direct, indirect, and two-zone cooking configurations.

• One Deflector: Creates direct and indirect cooking zones for grilling foods requiring different heat levels or reverse searing.
• Two Deflectors: Provides full indirect coverage for smoking, roasting, and low-and-slow barbeque.

Looking for More Indirect Coverage in Your Medium Egg?

The CGS Medium Woo accommodates 12-inch to 14-inch half-moon deflectors. While the 12-inch deflectors fit, we recommend the larger 14-inch half-moons for wider indirect heat coverage and better protection from direct charcoal heat.

Small Big Green Egg – CGS Woo Setups

The 12-inch half-moon deflectors work with select CGS Woo setups for the Small Big Green Egg.

Depending on the rack configuration, one deflector can provide partial indirect coverage for two-zone cooking, while a pair offers broader heat protection beneath the raised cooking grid for smoking, roasting, and barbeque.

Before Ordering: Check your CGS Woo configuration to confirm the correct deflector placement, support, and clearance.

MiniMax Big Green Egg – CGS Woo Two-Zone Setup

A single 12-inch half-moon deflector can create a two-zone cooking setup in the MiniMax Big Green Egg when used with a compatible CGS Woo.

The ceramic shields part of the cooking area from direct charcoal heat while leaving the opposite side open for direct grilling. This allows you to cook foods requiring different heat levels or move food between direct and indirect zones.

Our Recommendation: Use one 12-inch half-moon for this MiniMax two-zone configuration. CGS does not recommend using two 12-inch deflectors for full indirect cooking in the MiniMax.

Pizza Setups, Drip Pans & Ceramic Care

Using Half-Moon Deflectors for Pizza

The 12-inch half-moon deflectors can serve as a lower heat barrier in compatible pizza setups. Position a separate pizza stone above the deflectors with an air gap between the ceramic layers.

The lower ceramic shields the pizza stone from concentrated direct charcoal heat while the air gap helps promote more balanced baking temperatures.

Protect Your Deflectors with a Drip Pan

For low-and-slow barbeque, we recommend using a stainless steel drip pan above the deflectors whenever your setup allows.

Ceramic is porous and can absorb grease and moisture. A drip pan helps prevent grease buildup, protects the ceramic, and simplifies cleanup.

Ceramic Deflector Care & Maintenance

• Do not use soap, detergents, or chemical cleaners on the porous ceramic.
• Do not submerge the ceramic in water or place it in a dishwasher.
• Scrape away loose food residue after the ceramic cools.
• Use a drip pan to help prevent heavy grease buildup.
• Avoid aggressive high-temperature cleaning burns.
• Allow the ceramic to heat and cool gradually whenever possible.
• Expect the ceramic surface to darken with normal cooking and smoke exposure.
