Multigrain Seeded Sourdough Boule with Dutch Oven Method

A hearty artisan sourdough boule packed with whole grain cereals and seeds for rich texture and nutty flavor. The combination of sourdough starter and instant yeast creates reliable rise with complex tangy notes, while the Dutch oven method produces a crispy crust and tender crumb. Perfect for sandwich slicing or serving alongside soups and stews. The multigrain blend adds protein and fiber, making this more nutritious than standard white sourdough. Seeds on top provide extra crunch and visual appeal.

Tips

Tip 1

The multigrain mixture should cool completely before adding other ingredients to avoid killing the yeast and sourdough cultures.

Tip 2

Dutch oven creates steam for the first half of baking, producing a crispy crust. Parchment paper prevents sticking and makes removal easier.

Tip 3

Internal temperature of 190 degrees ensures the bread is fully baked through the dense grain mixture.
