Begin by bringing a large pot of salted water to a vigorous boil. Carefully add the gnocchi and cook them according to the package instructions, which usually indicates they are done when they float to the top. Once cooked, drain the gnocchi and set them aside for later use.
In a large skillet, heat the olive oil over medium heat. Once hot, add the finely chopped onion and sauté for approximately 2-3 minutes, or until the onion becomes translucent and fragrant. Incorporate the minced garlic into the skillet and sauté for an additional minute, being careful not to let it burn.
Stir in the diced red and green bell peppers into the skillet. Sauté the mixture for about 5-7 minutes, or until the peppers are tender and vibrant in color.
Reduce the heat to low and carefully pour in the heavy cream, stirring continuously to combine with the vegetables. Sprinkle in the Cajun seasoning, ensuring an even distribution throughout the mixture. Allow the sauce to simmer gently for about 3-4 minutes, or until it thickens slightly.
Gently fold the cooked gnocchi into the sauce, carefully stirring until each piece is well-coated with the creamy mixture. Gradually add the freshly grated Parmesan cheese, mixing thoroughly until it melts and creates a rich, creamy texture. Taste and season with salt and pepper as desired.
Once everything is well combined and heated through, remove the skillet from the heat. Garnish with freshly chopped parsley for a pop of color and flavor before serving.
Notes
Serve with crusty bread to soak up the extra sauce.
