01 - Whisk together flour, salt, and instant yeast in a large mixing bowl until thoroughly blended.
02 - Add grated sharp cheddar to the dry mixture and toss well to distribute evenly throughout.
03 - Pour lukewarm water into the bowl and mix with a wooden spoon or spatula until a shaggy, sticky dough comes together.
04 - Cover the bowl tightly with plastic wrap or a clean towel. Let rise at room temperature for 3–4 hours until doubled in size with bubbles on the surface.
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 risen dough out, shape into a round loaf, and place on parchment paper.
07 - Cover dough with a towel and let rest for 20–30 minutes while the oven continues preheating.
08 - Using oven mitts, carefully remove the hot pot from the oven. Lift the dough with parchment paper and lower it into the pot.
09 - Cover with the lid and bake for 30 minutes to create steam and develop the crust.
10 - Remove the lid and bake for an additional 10–15 minutes until the crust is deep golden brown and the loaf sounds hollow when tapped on the bottom.
11 - Transfer the loaf to a wire rack and let cool for at least 30 minutes before slicing to ensure proper texture.
