In a large pot, bring salted water to a boil. Add the potato gnocchi and cook according to package instructions until they float to the top, about 2-3 minutes. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant but not browned.
Add the chopped spinach to the skillet and cook for 2-3 minutes until wilted.
Pour in the heavy cream, lemon juice, and lemon zest, stirring well to combine. Allow the mixture to simmer for about 3-4 minutes, letting it slightly thicken.
Gently stir in the cooked gnocchi, making sure to coat them well in the creamy sauce.
Sprinkle in the grated Parmesan cheese and mix until melted and creamy. Season with salt, pepper, and red pepper flakes to taste.
Remove from heat and serve immediately, garnished with extra Parmesan and lemon zest if desired.
