First, start by cleaning the asparagus. Cut the end of the stem and scrape the hardest part with a knife.
Divide the tips from the stems, put the latter in a pan of cold water and cook for about 10 minutes or until they are soft.
Place the steaming tips in a basket on top of the broth pot.
Once the tips and stems are cooked, keep them aside and let them cool.
Cut the stems into small pieces, putting aside the part that will be harder that you will then blend with a little cooking water until you get a cream.
Finely slice the onion and put it in a saucepan with the oil and a knob of butter.
Add the rice, toast it for a few minutes on medium-high heat.
Pour the wine and let it evaporate.
Add the asparagus cream and a couple of ladles of hot broth. Continue cooking the rice by adding a ladle of broth as it is absorbed, stirring constantly.
About halfway through cooking add the asparagus cut into small pieces.
When cooked, season with salt and pepper, add the asparagus tips and remove from the heat.
Add the butter and Parmesan, let stand for a few minutes, then mix everything gently.
Serve your risotto with asparagus hot.
