In a large high-sided skillet, melt 2 tablespoon butter over medium-high heat. Add gnocchi and cook 6–8 minutes, stirring every 1–2 minutes, until crisp on the outside and soft inside. Transfer to a paper towel–lined plate.
In the same skillet, melt remaining 2 tablespoon butter. Add mushrooms and onions. Cook 4–6 minutes, stirring often, until tender.
Add garlic, Worcestershire sauce, and thyme. Cook 1 minute more.
Sprinkle evenly with flour and cook 1 minute, stirring to coat.
Add white wine and cook 1 minute more, stirring constantly.
Stir in beef broth and bring to a gentle simmer.
Reduce heat to medium-low. Stir in heavy cream and parmesan. Cook, stirring continuously, until thickened.
Add a pinch of nutmeg, season to taste with salt & pepper, and fold in the pan-fried gnocchi.
Serve warm and enjoy.
Notes
Clean mushrooms with a paper towel to remove any dirt before slicing.
Pan fried gnocchi becomes crispy on the outside and light and fluffy on the inside.
For softer gnocchi, it can be simmered in a pot of boiling water instead of pan fried.
If sauce becomes too thick, add a splash of broth or cream.
