Heat up a stone bowl, lightly oiled, over medium-low heat until very hot.
Add the rice to the pot, and top with cheese and sauce. Place the egg on top and make it rain parmesan. Add parsley, if using.
If you’re serving it at the table, carefully bring the bowl to the table. Mix everything up, pushing the rice up the sides of the bowl. You should hear a bit of a sizzle. Let crisp for a couple of minutes. The mix of rice and cheese will form a crispy frico/socarrat. The longer you wait, the crispier it will get. Enjoy!
Notes
Feel free to use your favorite bolognese sauce and type of egg. I had some slow poached eggs in the fridge, so it worked out well for me, but a simple soft boiled egg or crispy sunny side up egg would work just as well.
