Hi.. not fast.. is im used to cook this type of spaghetti. While boiling the spaghetti(must be very boiling water with salt) to Al Dente, i sauteed the mushrooms and other ingredients and once the spaghetti is ready, I put them into the pan where the mushrooms are and I stir fried it. Then.add some italian herbs and Viola.. my aglio olio spaghetti is done. I only use, black pepper, italian herbs and salt. No dressings.
