Preheat: The next morning, or when you’re ready to bake your funfetti sourdough, place your Dutch oven with the lid on into the oven and preheat to 500°F for 30–60 minutes. A fully heated Dutch oven is key for a strong oven spring, so don’t skip this step.
Score: Remove the dough from the fridge and place a piece of parchment over the top. Carefully flip the dough out onto the parchment. Using a bread lame or sharp knife, score at about a 45° angle, cutting just beneath the surface skin of the dough. One long score along the side works beautifully to let the loaf expand.
Bake: Carefully remove the hot Dutch oven, take off the lid, and use the parchment to lower the dough inside. Cover and bake at 500°F for 30 minutes. Remove the lid and lower the temp to 450°F, then bake an additional 10–15 minutes, until the crust is golden brown or the internal temperature reaches 208–210°F. Transfer to a wire rack and let cool completely (1–2 hours) before slicing to reveal those colorful funfetti sprinkles.
Enjoy! Enjoy your delicious homemade funffetti sourdough bread with any of your favorite toppings like, whipped brown butter or cream cheese!
