Making Gruyere Stuffed Crusty Loaves is an enjoyable process. Follow these steps for a delicious result:

1. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, salt, and instant yeast until well combined.
2. Add Wet Ingredients: Pour in the warm water and olive oil. Stir until a shaggy dough forms.
3. Knead the Dough: Transfer the dough to a floured surface and knead for about 10 minutes until smooth and elastic.
4. First Rise: Place the dough in a lightly oiled bowl, cover with plastic wrap, and let it rise in a warm place for about 1 hour, or until doubled in size.
5. Prepare the Cheese Filling: While the dough rises, mix the shredded Gruyere cheese with the chopped rosemary in a bowl. Set aside.
6. Shape the Loaves: Once the dough has risen, punch it down and divide it into two equal portions. Shape each portion into a rectangle.
7. Fill with Cheese: Sprinkle half of the Gruyere mixture on each rectangle. Roll the dough tightly, starting from the long side, to encase the cheese.
8. Second Rise: Place the loaves seam-side down on a baking sheet dusted with cornmeal. Cover and let them rise for another 30 minutes.
9. Preheat Oven: While the loaves are rising, preheat your oven to 425°F (220°C).
10. Score the Loaves: Using a sharp knife, make a few diagonal slashes on the top of each loaf to allow steam to escape during baking.
11. Bake: Place the loaves in the preheated oven and bake for 25-30 minutes until golden brown and crusty.
12. Cool: Remove the loaves from the oven and let them cool on a wire rack for 10-15 minutes before slicing.
