Step 1: Roast the Garlic
Preheat oven to 400°F. Slice the top off a garlic bulb to expose the cloves, drizzle with olive oil, wrap in foil, and roast for 35–40 minutes until soft and golden. Let cool, then squeeze out the softened garlic cloves.

Step 2: Mix the Dough
In a large bowl, combine flour, salt, and yeast. Add the warm water, rosemary, and roasted garlic cloves. Mix with a wooden spoon until a shaggy dough forms. Cover with plastic wrap or a clean towel.

Step 3: Let It Rise
Let the dough rest at room temperature for 12–18 hours, or until it has doubled in size and the surface is bubbly.

Step 4: Shape and Rest Again
Turn the dough onto a floured surface. Gently shape it into a ball using floured hands. Place on parchment paper and cover with a towel. Let rise again for 30–60 minutes.

Step 5: Preheat and Bake
Preheat your Dutch oven at 450°F for at least 30 minutes. When ready, carefully lift the dough with parchment and place it inside the pot. Cover and bake for 30 minutes. Uncover and bake an additional 10–15 minutes until golden brown.

Step 6: Cool and Slice
Remove from the pot and let the loaf cool on a wire rack for at least 20 minutes before slicing.
