Compare the Baking Steel Kamado for Big Green Egg grills and the Outdoor Oven Steel for portable pizza ovens. Learn which steel fits your outdoor setup.
Quick answer
Choose the Baking Steel Kamado if you own a Big Green Egg or similar kamado grill. Choose the Outdoor Oven Steel if you use a small portable pizza oven like Ooni or Frya. The right steel matches your cooking surface, not just your oven type.
Shape and size matter for your grill or oven
The Baking Steel Kamado is a 16-inch round steel designed specifically to fit Big Green Egg kamado grills. Its round shape matches the circular cooking surface of a kamado, so heat distributes evenly and the steel sits flat. If you try to use a square or rectangular steel in a kamado, you lose cooking space and get uneven heating.
The Outdoor Oven Steel is 13.5 by 13.25 inches and 1/4 inch thick, weighing 15 pounds. It is sized for small Ooni Ovens (excluding the PRO Model and 16-inch models) and Frya 12 ovens. This rectangular shape fits the narrow footprint of portable pizza ovens, where a round steel would not sit properly or would block airflow.
Heat retention and cooking performance
Both steels are made from the same conductive material, so they deliver the high heat needed for a crispy crust in minutes. The key difference is how they fit your cooking environment. The Kamado steel benefits from the kamado's excellent insulation, holding steady high heat for multiple pizzas. The Outdoor Oven Steel works with the intense direct flame of a portable oven, giving you that charred, restaurant-quality finish.
If you already have a Big Green Egg, the Kamado steel turns it into a pizza oven without buying a separate appliance. If you own a small Ooni or Frya, the Outdoor Oven Steel boosts that oven's performance by adding thermal mass that compensates for temperature fluctuations.
Trade-offs at a glance
- Baking Steel Kamado: Best for Big Green Egg owners who want restaurant-quality pizza without buying a separate oven. The round shape matches the kamado's cooking surface, and the steel's high heat retention works with the grill's insulation. If you already own a kamado grill, this steel gives you a pizza oven upgrade without a new appliance.
- Outdoor Oven Steel: Best for owners of small Ooni Ovens (not the 16-inch models) or Frya 12. The rectangular shape fits the narrow oven cavity, and the 1/4-inch thickness adds thermal mass to stabilize temperature for crispy crusts. If you have a small portable pizza oven, this steel improves heat retention and crust quality.
- Shape and compatibility: The Kamado steel is round and 16 inches. The Outdoor Oven steel is rectangular and 13.5 by 13.25 inches. They are not interchangeable. Using the wrong shape wastes cooking space or blocks airflow. Always measure your grill or oven's cooking surface before choosing.
