Boil the fettuccine in salted water until al dente; reserve 1 cup pasta water and drain.
Melt the butter in a large skillet over medium-high heat and cook the mushrooms without stirring for 3 minutes, then stir and cook 5 more until browned.
Add the minced shallot, garlic, and thyme leaves and cook 1 minute.
Pour in the cream, add the peas, and simmer 3 minutes, then stir in the parmesan.
Toss with the fettuccine and enough pasta water to make it silky; season with salt and lots of black pepper.
