Baking Steel Plus

Bake 4 Sourdough Loaves at Once, or Two Pizzas Side by Side

The Baking Steel Plus (15" x 20") is a 22-pound slab of solid carbon steel built for open baking bread and making multiple pizzas at once. Bake 4 sourdough loaves simultaneously or two 12-inch pizzas side by side with the same blistered crusts, explosive oven spring, and even heat that made Baking Steel the #1 choice for serious home bakers and micro bakeries. Steel conducts heat 18 times better than ceramic, delivering bakery-quality results in a home oven.

Pre-seasoned and ready to use right out of the box. Made in the USA. Lifetime warranty.

Perfect For:

•

Micro bakers who sell bread and need to scale production without commercial equipment

•

Serious bread bakers who want to open bake multiple sourdough loaves at once

•

Pizza party hosts cooking for crowds — two pizzas at a time

•

Home bakers upgrading from Dutch ovens to faster, more efficient open baking

•

Stovetop griddle users — flip it over for smashburgers, pancakes, and quesadillas (gas, electric, and induction)

Why Is Open Baking Better Than a Dutch Oven?

Open baking means baking loaves directly on a preheated steel surface, no Dutch oven, no heavy lids, no one-loaf bottleneck. The Baking Steel Plus retains and radiates heat like a professional deck oven, giving you results that rival commercial bakeries.

A Dutch oven bakes one loaf at a time. The Plus bakes four. No heavy lids to remove mid-bake. Faster workflow. Better oven spring. And the steel is also a pizza machine, stovetop griddle, and sheet pan supercharger, a Dutch oven can't do any of that.

For Micro Bakers: Your Production Breakthrough

If you're selling bread from your home kitchen, the Plus is your secret weapon. Bake 4 loaves per steel — or use two Plus steels to bake 8 loaves at once in a standard home oven. Go from 12 loaves a day to 32+ without upgrading your oven. Faster turnaround, more sales, no commercial equipment needed.

Pair it with our 15" x 20" Bread Board — load your proofed loaves onto the board, slide them onto the steel, then use the board to cool your finished loaves. The Plus and Bread Board were designed together as the ultimate bread-baking system.

What Can I Make With the Baking Steel Plus?

Bread: Sourdough, no-knead, baguettes, focaccia, sandwich loaves, English muffins — 4 loaves at once with incredible oven spring.

Pizza: Two 12-inch pizzas side by side. Same blistered, crispy crusts in 5–7 minutes — perfect for pizza parties.

Everything else: Pastries, roasted vegetables, flatbreads, cookies. Flip it over on your stovetop or grill for smashburgers, pancakes, quesadillas, and seared steaks. Works on gas, electric, and induction.

How Do I Use the Baking Steel Plus?

Place it on the middle or upper rack. Preheat for 60 minutes at 500–550°F. For bread, load your proofed loaves directly onto the steel and bake according to your recipe (typically 35–45 minutes). For pizza, launch and bake for 5–7 minutes. For the full step-by-step method, read our complete guide →

Bread bakers asked for this one.

We made the Plus because bread bakers asked for it. They were baking one loaf at a time and wanted room for more, so we gave them room for four. We went as big as we could and still fit most home ovens. That's where 15 by 20 came from.

Fourteen years later, every Baking Steel is still made at my dad's shop in Hanover, Massachusetts, and every one still ships from there. More than 200,000 home cooks have one. I still run the company myself, and I teach free pizza classes on Zoom.

Frequently Asked Questions

What is open baking?

Open baking is a bread-baking technique where loaves are baked directly on a preheated steel surface without a Dutch oven.

How many loaves can I bake on the Baking Steel Plus?

Is the Baking Steel Plus better than a Dutch oven for bread?
