Cook the Gnocchi: Bring a large pot of salted water to a boil. Add the gnocchi and cook according to package instructions until they float to the surface, about 2-4 minutes. Drain and set aside.
Sauté Garlic: In a large skillet, heat olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds, or until fragrant.
Add Spinach: Add the chopped spinach to the skillet and sauté for about 2-3 minutes until wilted.
Create Creamy Sauce: Reduce the heat to low and pour in the heavy cream. Stir to combine and let it simmer for 2-3 minutes until slightly thickened.
Combine Ingredients: Add the cooked gnocchi to the skillet, tossing to coat them evenly with the creamy spinach sauce.
Incorporate Feta: Gently fold in the crumbled feta cheese and season with red pepper flakes, salt, and pepper to taste. Let it heat through for an additional minute.
Serve: Remove from heat, and plate the creamy gnocchi mixture. If desired, garnish with fresh basil leaves for an added burst of flavor.
