Heat a medium pot over medium-high heat and add the butter. Once melted, add the onions and cook until soft and translucent, stirring occasionally, about 5-10 minutes. Add the garlic and cook until fragrant, one minute more. Add Italian seasoning and drained bell peppers. Cook another 5 minutes.

Transfer cooked mixture to a blender and add the cream. Blend until completely smooth and then return to the pot. Add the noddles and heat until the entire dish is steaming but does not boil. Stir in parmesan and season to taste with salt and pepper then garnish with additional parmesan and herbs, if desired.
