I always start by boiling salted water in a large pot. Once it reaches a rolling boil, I add the pasta and cook it until al dente. Then I drain it and keep a little pasta water aside for later.
I heat olive oil and butter in a pan until melted and slightly bubbling. Then I add sliced mushrooms and cook them until golden and soft. This step builds the earthy base flavor of the entire sauce.
Next, I stir in minced garlic and let it cook briefly until fragrant. I make sure not to burn it because it can turn bitter quickly. This adds a warm aromatic layer to the sauce.
I pour in the heavy cream and gently stir it with the mushrooms. Then I add crumbled gorgonzola and let it melt slowly into the sauce. The mixture becomes thick, rich, and beautifully creamy.
I drizzle in truffle oil and season with salt and pepper carefully. Then I toss in the cooked pasta and mix until fully coated. If needed, I add a splash of pasta water to loosen the sauce
