Prepare all the ingredients: grate the mozzarella and Parmesan cheese, chop the rosemary, and set aside.
Crack the eggs into a bowl and whisk them with a fork. Add the milk, salt, and pepper, and mix well.
In another bowl, combine the flour and cornstarch. The cornstarch helps to make the soufflé lighter and airier.
Gradually add the flour mixture to the egg mixture while continuously whisking to prevent lumps from forming. Mix everything well until you have a smooth, creamy consistency.
Add the grated mozzarella, Parmesan cheese, and chopped rosemary, and fold them into the batter.
Choose a suitable size oven-safe dish for baking the soufflé, and grease it with a thin layer of butter or olive oil to prevent sticking.
Pour the batter into the dish and bake in a preheated oven at 350°F (180°C) for about 25-30 minutes, or until the soufflé has risen nicely and is golden brown on top.
Once done, remove from the oven and let it rest for a few minutes before slicing. This makes it easier to slice and helps the soufflé retain its shape.
