Cut the mushrooms into slices slightly thicker than you would like to eat them: they will shrink further. If they are very dirty, brush them clean first.
250 g cremini mushrooms
Brown on all sides over fairly high heat. Sprinkle with salt halfway through cooking.
3 pinches salt, 3 generous splashes extra virgin olive oil
Let the mushrooms drain in a small sieve or colander. Be sure to save the juices!
Meanwhile, finely chop the onion and press the garlic.
1 red onion, 2 cloves garlic
Add another splash of oil to the pan. Sauté the onion until translucent. Add the garlic only at the end.
Process the cauliflower into rice. You can do this in a large food processor fitted with an S-shaped blade.
300 g cauliflower
Add the cauliflower rice and a splash of oil. Stir a few times to blend the flavors. Add the pepper and herbs.
2 pinches black pepper, 1 tablespoon herbs
Add the reserved mushroom juices. You need 3 to 4 tablespoons of liquid. If there is not enough, top up with water.
Simmer for 6 to 7 minutes over medium-high heat.
Grate the cheese.
100 g Pecorino
Lower the heat slightly. Add the cheese and let it melt.
Stir in the mushrooms.
Notes
You can buy ready-made cauliflower rice, but simply processing the cauliflower yourself is much cheaper and fresher.Equipment: large PFAS-free frying pan, grater (four-sided), sieve + bowl to collect the juices, food processor.
