Prepare the Dough:
In a large mixing bowl, combine the flour, yeast, salt, and sugar.
Gradually pour in warm water while stirring with a wooden spoon. Mix until a shaggy dough forms.
Fold in the diced jalapeños and shredded vegan cheddar until evenly distributed.
Knead and Rest:
Transfer the dough to a lightly floured surface and knead for 5–7 minutes until smooth and elastic.
Place the dough back in the bowl, cover with a kitchen towel or plastic wrap, and let it rise in a warm spot for 1–2 hours until doubled in size.
Shape the Dough:
Once risen, gently punch the dough to release the air.
Shape it into a round loaf and place it on parchment paper. Cover again and let rest for 30 minutes.
Preheat the Oven:
Preheat your oven to 450°F (232°C). Place a Dutch oven or baking stone inside to heat up.
Bake the Bread:
Carefully transfer the dough (on the parchment paper) into the preheated Dutch oven or onto the baking stone.
Cover the Dutch oven with its lid and bake for 25 minutes.
Remove the lid and bake for another 10–15 minutes until the crust is golden brown and crisp.
Cool and Serve:
Remove the bread from the oven and allow it to cool on a wire rack before slicing.
