First cut the broccoli florets, peel the stem and cut it into small pieces. Rinse under running water. Boil in boiling salted water for ¾ minutes.
Heat the broth.
Finely slice the white part of the leek. Heat the oil in a large saucepan over medium heat, add the leek and let it dry, adding a drop of hot broth if necessary.
In the mixing bowl of the immersion mixer, put ¾ broccoli and the leek and roughly reduce.
Fry the finely chopped onion with the oil in the pan used previously.
Turn up the heat, add the rice, stir and let it toast for about a minute until the grains become shiny, stirring constantly. Deglaze with the wine and let it evaporate.
Reduce the heat and cook the risotto by adding a ladle of broth and stirring, until the broth is absorbed.
Keep adding the broth one ladle at a time, until the risotto is ready (this will take about 16/18 minutes, depending on the type of rice).
Halfway through cooking add the broccoli cream, the broccoli florets and continue cooking.
In the meantime, fry the bacon in a non-stick saucepan without seasoning until crispy. Add to the risotto.
Once the risotto is ready, remove it from the heat, season with salt and pepper and add the cheese.
Let it sit for a minute, to allow the cheese to melt, then mix everything well together.
Serve your broccoli risotto.
