Bring a large pot of salted water to a boil and cook the pasta until al dente. Reserve 1/2 cup of the pasta water before draining.
In a large skillet, warm the olive oil over medium heat. Add garlic and cook until fragrant.
Toss in the mushrooms and sauté until they’re golden brown and tender.
Pour in the heavy cream, stirring gently, and let it simmer for 2–3 minutes.
Add the gorgonzola and stir until melted into a smooth sauce.
Splash in a bit of the reserved pasta water to loosen the sauce if it feels too thick.
Toss the cooked pasta into the skillet, coating every strand in that creamy goodness.
Remove from heat, drizzle with truffle oil, season with salt and pepper, and garnish with parsley.
Serve immediately, preferably with a glass of wine in hand.
