In this guide, you’ll learn:

  • What the Two-Loaf Pan Method is
  • Why steam matters in sourdough baking
  • Step-by-step instructions for the method
  • Tips for baking in bulk
  • Recommended tools and supplies
  • How this method can save you thousands in startup costs

Let’s dive in!


What Is the Two-Loaf Pan Method?

The Two-Loaf Pan Method is a smart alternative to using a Dutch oven for baking sourdough bread. Instead of a cast iron pot, you use two loaf pans—one as the base and one as a lid—to trap steam inside.

Why It Works

  • Traps natural steam from the dough
  • Creates a mini steam oven inside your home oven
  • Works in both electric and gas ovens
  • Allows you to bake more loaves at once

Why Steam Is Essential in Sourdough Baking

Steam makes a big difference in how your sourdough turns out. Here’s why:

  • Better oven spring: Steam keeps the crust soft during the first phase of baking, so the dough can rise more.
  • Airy crumb: Moisture lets the dough expand evenly for an open, soft interior.
  • Beautiful crust: Steam helps caramelize sugars, giving your loaf a glossy, golden finish.
  • Improved scoring: Steam helps your cuts expand instead of sealing up too fast.

Why Home Bakers Love the Two-Loaf Pan Method (Hint: It Saves You $$$)

One of the biggest reasons home and micro bakers love the Two-Loaf Pan Method is its cost-saving power. Commercial steam-injected ovens can cost thousands of dollars—and that’s before factoring in the space and power requirements. Even multiple cast iron Dutch ovens can quickly add up in price and wear you down physically.

With the Two-Loaf Pan Method, all you need are standard loaf pans. You can outfit your entire setup for a fraction of the cost—allowing you to scale up your baking operation without taking on massive debt or burning out from lifting heavy equipment all day.

For micro bakeries or side hustles, this is a game-changer. You can start producing beautiful, crusty sourdough loaves in bulk without needing a professional kitchen or commercial gear. That means more profit margins, faster return on investment, and lower startup costs.

What You’ll Need

1. Loaf Pans

2. Greasing the Pans

  • Best oils: Avocado, coconut oil, butter, or ghee
  • Use parchment paper for easier cleanup and no sticking

How to Use the Two-Pan Method: Step-by-Step

  1. Prepare Your Dough
    After the first rise (bulk fermentation), divide and shape into 900g batards. Place them seam-side down in greased or parchment-lined loaf pans.
  2. Proof
    • On the counter for a mild flavor
    • Or in the fridge (cold ferment) for deeper flavor
  3. Preheat Your Oven
    Set it between 450°F–500°F depending on your oven.
  4. Score the Dough
    Use a sharp blade for beautiful expansion.
  5. Cover with Second Pan
    Place a second loaf pan upside down to act as a lid and trap steam.
  6. Bake
    • Bake with the lid for 30 minutes (between 450°F-500°F, depending on how many loaves)
    • Remove the lid, lower temperature to 450°F
    • Bake another 15 minutes or until internal temp is 205°F
  7. Cool Completely
    Remove from the pan and let cool on a rack before slicing or storing.

Bulk Baking: Big Results Without a Big Budget

One of the biggest advantages of the Two-Loaf Pan Method is how well it scales. Whether you’re baking a few loaves a week for friends or 24 loaves a day for customers, this method helps you do it efficiently—without needing to invest in industrial equipment.

Your home oven becomes your bakery oven. By simply organizing your racks and using multiple sets of loaf pans, you can bake high volumes with consistent quality. That’s the kind of flexibility and affordability most commercial setups can’t compete with.


Recommended Tools

  • Stainless steel loaf pans
  • Parchment paper
  • Silicone oven gloves (high grip)
  • Digital thermometer
  • Bread lame for scoring
  • Dough mixer (for high volume baking)

Final Thoughts

The Two-Loaf Pan Method is a game-changer for any sourdough baker looking to save time, money, and effort. With this technique, you can:

  • Bake multiple loaves in a single oven session
  • Achieve consistent, bakery-quality results
