01 - In a large mixing bowl, whisk together the flour, salt, and instant yeast until uniformly blended.
02 - Add the grated cheddar and toss to distribute evenly throughout the flour mixture.
03 - Pour in the lukewarm water and mix with a wooden spoon or spatula until a shaggy, sticky dough forms.
04 - Cover the bowl tightly with plastic wrap or a clean towel. Let dough rise at room temperature for 3–4 hours, or until doubled in size with bubbles on the surface.
05 - Preheat your oven to 450°F. Place a Dutch oven or heavy pot with lid inside to heat for at least 30 minutes.
06 - Lightly flour a work surface and your hands. Carefully turn the dough out, shape it 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 the parchment paper and lower it into the pot.
09 - Cover with the lid and bake for 30 minutes to develop 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 at least 30 minutes before slicing to ensure proper texture.
