The Big Green Egg Split Deflector is a half-moon ceramic heat deflector for the Large EGG that enables true dual-zone cooking from a single cooker. Place one piece on one side of the EGG and that half becomes indirect. The other half, with no deflector beneath it, stays direct over the charcoal. One EGG, two heat zones, at the same time. Can also be used individually as a half baking stone, or as a pair to replicate full convEGGtor coverage across the entire cooking surface. Sold as one piece per listing with a 3-year limited warranty.
The Two Zones Explained
Where the Deflector Is
Indirect Zone
The ceramic Split Deflector sits between the charcoal and the cooking grid on this side. Heat radiates around and up rather than directly onto the food. Use this side for foods that need gentle, even heat without a direct flame: baking, smoking, finishing thick cuts, or cooking delicate proteins.
Where There Is No Deflector
Direct Zone
The other half of the cooking grid sits directly above the charcoal with no barrier. Full direct heat for grilling, searing, and crisping. Use this side for steaks, burgers, chops, vegetables, or anything that benefits from direct flame contact and high surface heat.
Why This Matters for Real Cooks
The standard convEGGtor is a full-circle deflector that converts the entire EGG to indirect heat. That is the right tool for a full brisket or a whole chicken where you want indirect all the way through. But it is the wrong setup when you want to sear a steak and then move it off the heat to finish, or grill chicken wings on direct while a batch of vegetables roasts gently on the other side. The Split Deflector creates the two-zone setup that experienced grill cooks use for almost every service meal. Direct for the fast cooks, indirect for the slower ones, and the ability to move food between zones without leaving the EGG.
Features
Feature 01
True Dual-Zone Cooking
One piece creates two distinct heat zones simultaneously. Sear on the direct side, finish on the indirect side, without removing the food from the EGG or disrupting the temperature. Entrees and sides can cook concurrently on the same cooker using different methods.
Feature 02
Works as a Half Baking Stone
Used individually, the Split Deflector functions as a half-moon baking stone for bread, pizza, flatbreads, or smaller items that do not need the full cooking surface. Useful when cooking alongside something on the other half of the grid, such as baking a focaccia on one side while vegetables grill on the other.
Feature 03
Use Two as a Full Deflector
Two Split Deflectors placed together cover the full cooking surface of the Large EGG, replicating the coverage of the standard convEGGtor. If you already own one and want full indirect coverage, a second piece completes the setup. Each piece is sold separately.
Feature 04
Improved BGE Ceramic
Made from BGE's upgraded ceramic formula, which delivers more consistent heat distribution and better edge performance than previous versions. Even heat across the indirect zone without hot spots at the centre or cooler areas at the edges of the half-moon shape.
Available for in-store pickup at BBQ Republic, Wetherill Park. BGE Australia advises that this ceramic item carries a transit damage risk and recommends collecting from a stockist rather than ordering for delivery. BBQ Republic stocks the Large Split Deflector at our 5 Vicars Place showroom. Come in and collect it directly to eliminate the transit risk entirely.
Care and Maintenance
- After baking, allow the EGG to remain at baking temperature for approximately 15 minutes to burn off residue on the stone surface.
- Use a long-handled brush to scrape the warm stone while still at temperature. Do not use water on a hot stone.
- Flip the stone on each subsequent cook. Rotating and flipping regularly allows residue to burn away progressively without needing to scrub the surface.
- Keep moisture away from the stone between cooks. Store in a dry location or leave in the EGG under the dome.
- Do not place a cold stone into a very hot EGG. Let the stone warm up with the EGG gradually to avoid thermal shock cracking.

Common Questions
How many Split Deflectors do I need?
It depends on what you want to do. One piece creates a dual-zone setup: indirect on one side where the deflector sits, direct on the other where there is no deflector. This is the most common use case and requires only one piece. Two pieces together cover the full cooking surface, replicating a full convEGGtor for entirely indirect cooking. Most buyers purchase two so they have the flexibility to use one or both depending on the cook.
What is the difference between the Split Deflector and the convEGGtor?
The convEGGtor is a full-circle deflector that converts the entire EGG cooking surface to indirect heat. It is one piece covering the whole grid. The Split Deflector is a half-moon shape. One Split Deflector creates two zones simultaneously, which the full convEGGtor cannot do. Two Split Deflectors together provide full coverage similar to the convEGGtor. The Split Deflector gives you more flexibility at the cost of needing two pieces for full indirect coverage.
Why does BGE recommend pickup rather than delivery for this product?
Ceramic items can crack under the impact stress of freight and courier handling. BGE Australia flags this product as having a transit damage risk and recommends collecting from a stockist rather than having it delivered. BBQ Republic stocks the Large Split Deflector at our Wetherill Park showroom. Collecting in person eliminates the transit risk entirely and lets you inspect the piece before leaving.
Does the Split Deflector fit the Large EGG only?
This listing is for the Large EGG. A separate XL version is available for the XL EGG. The two sizes are not interchangeable. Confirm your EGG size before ordering. If you have an XL EGG, ask us about the XL Split Deflector variant.
Is this a genuine Big Green Egg accessory?
Yes. The Split Deflector (SKU 136220) is a genuine Big Green Egg accessory supplied through the official BGE Australia distribution network. BBQ Republic is a Platinum Authorised Big Green Egg Dealer, meaning all BGE products we stock are genuine and covered by the manufacturer's warranty.
