Creamy Oyster Mushroom Pasta

Initiate a large pot of water and bring it to a rolling boil, having added a moderate amount of salt. Cook the linguine in the boiling water until it reaches an ideal level of doneness, still retaining a slight firmness when bitten into, approximately 11 minutes.

Transfer the cooked pasta to a serving dish.

Melt butter in a large skillet over a medium heat setting, allowing it to reach a stable temperature. Add sliced mushrooms and cook, stirring occasionally, until they become tender and lightly browned, taking around 5 minutes.

Combine chopped parsley, salt, and black pepper in the skillet; stir until the flavors meld together, approximately 1 minute. Introduce heavy cream into the mixture and bring it to a gentle simmer; cook until the sauce thickens slightly, roughly 5 minutes.

Pour the prepared sauce over the pasta in the serving dish; mix well to combine. Add chopped green onions and grated Parmesan cheese; stir until they are evenly distributed.
