Step 1: Prepare the Semolina Mixture
In a large pot, heat the milk over medium heat until it begins to simmer.
Gradually whisk in the semolina flour, salt, black pepper, and nutmeg (if using). Stir continuously to prevent lumps.
Cook for about 10-15 minutes, or until the mixture thickens into a smooth paste. You want it to be thick enough to hold its shape.
Step 2: Add Cheese and Egg Yolks
Once thickened, remove the pot from the heat.
Stir in the grated Parmigiano-Reggiano cheese and butter until melted and combined.
Let the mixture cool slightly, then add the egg yolks and mix well. This step helps bind everything together.
Step 3: Shape the Gnocchi
On a clean, floured surface, pour the semolina mixture and spread it out evenly to about 1/2 inch thick.
Let it cool completely for about 10 minutes.
Using a round cutter or knife, cut the gnocchi into circles or squares.
Step 4: Assemble the Gnocchi
Preheat your oven to 400°F (200°C).
Grease a baking dish with butter or oil.
Arrange the shaped gnocchi in the dish, overlapping slightly if necessary.
Sprinkle with extra cheese and breadcrumbs for a crispy topping.
Step 5: Bake
Bake in the preheated oven for about 20-25 minutes or until golden brown and bubbly.
Once done, remove from the oven and let it stand for a few minutes before serving.
