Begin by combining 2⅓ cups (300g) bread flour, 1 × ¼-ounce (7g) packet fast-acting dried yeast, 2 tbsps (30g) salted butter (melted), and 1 tsp salt in a large bowl. Stir the 2 crushed garlic cloves into ¾ cup + 3 tbsps (225ml) warm milk, then pour this mixture into the dry ingredients.
Mix everything together until a dough forms. Turn the dough out onto a floured surface and knead for 10 minutes until it becomes smooth and elastic.
Place the kneaded dough into an oiled bowl, cover it with a damp cloth or plastic wrap, and let it rise for about 1½ hours until it has doubled in size.
Once the dough has risen, preheat your broiler and lightly grease a baking sheet. Turn the dough out onto your work surface and knead the 1 small bunch of finely chopped cilantro into it.
Divide the dough into 6 equal pieces and roll each piece into a hand-sized teardrop shape, which is the characteristic shape of traditional naan bread.
Place three naans on the prepared baking sheet and brush them generously with olive oil. Broil them for 2–4 minutes per side until they achieve a golden-brown color.
Remove the first batch and repeat the broiling process with the remaining three naans. The naans should puff slightly and develop charred spots during cooking, indicating they're properly cooked and ready to serve.
