Melt the butter over medium heat. Add sliced mushrooms; sauté until golden. Once they’re golden, add salt – this will draw out some of the water. Cook the mushrooms down so some of the water can evaporate. Add garlic and sauté for 2-3 minutes, until fragrant.
Add broth, cream, and thyme. Bring to a simmer and let it cook for 5-10 minutes. Add cornstarch slurry to thicken. (This is a good time to boil your gnocchi if you haven’t already.)
Remove thyme sprigs from the sauce; add Parmesan and stir to melt it in. Add your cooked gnocchi and gently stir to combine. Season with salt and pepper; add additional broth if needed to keep the sauce nice and silky.
Scoop hot, steamy, saucy gnocchi into bowls, top with Parm, salt, and pepper, and enjoy your life.
