Start by rinsing and soaking dried porcini in drinking water. Water should be just enough to cover mushrooms. Steep dried porcini until they’re soft and water from steeping has become of amber color. This should take anywhere between 10-30 minutes.
In a large pan add a splash of extra virgin olive oil. Add garlic cloves crushed with a flat knife so they can better infuse the oil. Let them lightly brown on medium heat.
Add chopped shallot. Stir for a minute or two.
Add diced tomatoes and a pinch of peperoncino. Let simmer for a few minutes.
Finally, cut steeped mushroom in small pieces and add them to the pan.
Add as well liquid where the mushrooms have been soaked. Let simmer until sauce becomes creamy. Taste for salt.
Boil pasta according to directions on the package.
Drain and reserve some cooking liquid. Add dried oregano and pepper to taste.
Add pasta to the pan with the sauce and toss it until all is well combined.
