1. Activate the Yeast:

• In a small bowl, combine the warm water and sugar. Stir to dissolve the sugar, then sprinkle the yeast over the water. Let it sit for 5-10 minutes, or until the mixture becomes frothy. If the mixture doesn’t foam, your yeast may be expired, so it’s best to start over with fresh yeast.

2. Prepare the Dough:

• In a large mixing bowl, combine the flour and salt. Make a well in the center and add the yeast mixture, melted butter, and chopped rosemary. Stir with a wooden spoon or dough hook until the dough starts to come together.
• Once the dough is mostly combined, knead it on a floured surface for about 8-10 minutes, or until the dough is smooth and elastic. If you’re using a stand mixer, you can knead the dough with the dough hook for about 5-7 minutes.

3. Let the Dough Rise:

• Lightly grease a large bowl with olive oil and place the dough inside, turning it once to coat it in the oil. Cover the bowl with a clean kitchen towel or plastic wrap and place it in a warm spot to rise. Let the dough rise for 1-1.5 hours, or until it has doubled in size.

4. Shape the Rolls:

• Once the dough has doubled in size, punch it down to release any air bubbles. Turn the dough out onto a floured surface and divide it into 12 equal portions. Shape each portion into a smooth ball and arrange them in a greased 9×13-inch baking dish or on a large baking sheet lined with parchment paper. The rolls can be touching slightly, which will help them rise up rather than spread out.

5. Second Rise:

• Cover the rolls with a clean towel and let them rise for another 30-45 minutes, or until they have puffed up and are touching each other.

6. Bake the Rolls:

• Preheat the oven to 375°F (190°C).
• For a golden, glossy finish, you can brush the tops of the rolls with a beaten egg (optional). Melted butter works great too if you prefer a slightly softer finish.
• Bake the rolls in the preheated oven for 20-25 minutes, or until they are golden brown on top. If you want a little extra flavor, sprinkle coarse sea salt over the tops of the rolls about 5 minutes before they’re done baking.

7. Finish and Serve:

• Once the rolls are out of the oven, brush them with a little more melted butter for added flavor and a shiny finish. Let them cool for about 10 minutes before serving.
