In a large pot or Dutch oven, combine the vegetable broth and bean broth.
Bring to a gentle simmer over medium heat.
Once simmering, stir in the butter, paprika, and cayenne pepper until the butter has completely melted.
Season generously with salt and pepper to your liking.
Increase the heat to medium-high.
Add the fettuccine to the pot, breaking the noodles into smaller pieces if desired.
Cook, stirring occasionally, for about 15-20 minutes, or until the noodles are perfectly tender and have absorbed some of the flavorful broth.
