Boil the gnocchi according to recipe or package directions. Drain well.
While the gnocchi is cooking, add the butter and sage leaves to a large pan over medium high heat. Stir the butter occasionally until it begins to lightly brown and have a slightly nutty smell, about 2 minutes (the time can vary based on the type of pan).
Remove the butter from the pan and set aside.
Add the olive oil to the pan (add a few extra sage leaves if you have them to flavor the oil) and heat over medium-high heat. Add the drained gnocchi to the pan and cook until golden on one side without stirring, about 5-6 minutes.
Add the browned butter back to the pan and mix with the gnocchi. Cook 1-2 minutes.
Season generously with salt and fresh black pepper. Sprinkle with parmesan cheese and serve.
