01 - Whisk together flour, salt, and instant yeast in a large mixing bowl until thoroughly blended.
02 - Add grated sharp cheddar to the flour mixture, tossing evenly to distribute throughout.
03 - Pour lukewarm water into the bowl and mix with a wooden spoon or spatula until a shaggy, sticky dough forms.
04 - Cover bowl tightly with plastic wrap or a clean towel. Let rise at room temperature for 3–4 hours until doubled in size with surface bubbles.
05 - Preheat oven to 450°F. Place a Dutch oven or heavy pot with lid inside to heat for at least 30 minutes.
06 - Lightly flour work surface and hands. Turn dough out, shape into a round loaf, and place on parchment paper.
07 - Cover with a towel and let rest for 20–30 minutes while the oven continues heating.
08 - Using oven mitts, remove the hot pot from the oven. Lift the dough with parchment paper and lower into the pot.
09 - Cover with the lid and bake for 30 minutes to develop steam and internal structure.
10 - Remove the lid and bake another 10–15 minutes until the crust is deep golden and the loaf sounds hollow when tapped.
11 - Transfer to a wire rack and let cool for at least 30 minutes before slicing to ensure proper texture.
