Unidanho Eggspander for Large Big Green Egg — 5‑Piece Stainless Steel Kit, Multi‑Level Cooking Rack

The Unidanho Eggspander 5-piece kit converts a Large Big Green Egg into a multi-level, professional-grade cooking station that increases capacity and enables direct and indirect techniques.

If you own a Large Big Green Egg (18-inch grid), this stainless-steel Eggspander kit is an easy way to add flexibility and cooking surface without permanent modifications. The set nests into the existing ceramic shell and gives you immediate options for high-heat searing, low-and-slow smoking, wok cooking and multi-rack roasting. Every component is built to drop into place—no tools required—and designed to endure the high temperatures and heavy pans often used on kamado grills.

How does the Eggspander create more usable grill space?

The kit stacks components to form separate cooking tiers, letting you use the upper grids for vegetables or pizzas while the lower shelf handles meats. By creating distinct levels you effectively multiply the area available on the 18-inch grate, so one load can feed a crowd.

• Three-tier capability to separately cook different foods at different intensities
• Upper grids for quick items, lower rack for searing or smoking
• Fits the Large BGE 18-inch cooking surface for a seamless installation

Can I sear directly over the coals and still smoke simultaneously?

Yes — the Eggspander supports both direct high-heat grilling and indirect methods in the same cook. Insert the convEGGtor or move it to the lower position to block or expose heat, enabling adjacent zones for searing and low-temperature smoking at once.

• Lower rack places food closer to coals for intense open-flame searing
• ConvEGGtor placement creates a stable indirect-heat chamber for smoking
• Switch elements quickly to change from searing to roasting without dismantling the setup

What materials and construction should I expect for durability?

The kit is fabricated from solid stainless steel to resist warping and corrosion under repeated high-temperature use. Each piece is machined to fit the Large BGE precisely, and the components lock into position by design so heavier pans and roasts are supported safely.

• Heavy-gauge stainless steel resists high heat and long cooks
• Interchangeable parts drop into the egg—no bolts or tools needed
• Engineered to support weighty items like cast-iron woks or rib racks

What cooking styles and accessories does the Eggspander support?

This 5-piece system is built to be versatile: use it for searing steaks, low-and-slow brisket, baking pizza, stir-frying with a wok or holding ribs upright. The stackable design means you can customize the configuration for each session and pair it with common BGE accessories.

• Compatible with convEGGtor for reliable indirect heat
• Holds a wok securely for stir-fry or high-heat wok searing
• Creates space for rib racks, griddles, and pizza stones at once

Who this is for: Backyard chefs who want a multipurpose upgrade to their Large Big Green Egg will find the Unidanho Eggspander especially useful. It suits homeowners who entertain often, cooks who switch between high-heat and slow-smoke techniques, and anyone who needs to increase capacity without buying a second grill. If you want a heavy-duty, drop-in solution to broaden your kamado’s capabilities—while keeping setup simple—this kit is designed to deliver.
