In a large pot, bring salted water to a boil. Add the gnocchi and cook according to the package instructions until they float to the top. Drain and set aside.
In a large skillet over medium heat, melt the butter. Once melted, add the sage leaves and cook for about 1-2 minutes, until the leaves turn crispy and the butter starts to brown slightly.
Stir in the minced garlic and cherry tomatoes to the skillet. Sauté for about 2-3 minutes until the tomatoes begin to soften and the garlic is fragrant.
Add the cooked gnocchi to the skillet. Season with salt, black pepper, and red pepper flakes. Gently toss everything together in the sage butter, cooking for an additional 3-4 minutes.
Remove the skillet from heat and stir in the grated Parmesan cheese, mixing well until the gnocchi are coated in a creamy sauce.
Serve the gnocchi hot, garnished with fresh basil leaves and additional Parmesan cheese if desired.
Notes
Fresh basil and additional Parmesan can be used for garnish.
