I start by boiling a large pot of salted water until it’s well-seasoned like the sea. Then I add the pasta and cook it until al dente according to package instructions. Before draining, I always save a cup of pasta water for the sauce.
In a large pan, I heat olive oil and add sliced mushrooms in a single layer. I let them cook until golden brown so they release their natural earthy flavor. Then I add garlic and stir until fragrant, being careful not to burn it.
Next, I lower the heat and add Boursin cheese into the mushrooms. As it melts, I pour in a splash of pasta water to loosen the texture. This step creates a smooth, velvety sauce that starts coming together beautifully.
Now I drizzle in truffle oil slowly so it blends evenly into the sauce. I also add a bit of heavy cream for extra richness and silkiness. I keep stirring until everything becomes glossy and creamy.
Finally, I add the cooked pasta directly into the sauce pan. I toss everything gently so the pasta is fully coated in creamy goodness. If needed, I adjust consistency with more pasta water before serving.
