Heat 1 tablespoon neutral oil in a large pot over medium heat. Add the fennel and cook, stirring regularly, for 8–10 minutes until it softens. Season with salt and pepper.
Add the mushrooms and cook for 5–6 minutes.
Turn the heat to medium-high. Add the minced ginger and cook for 1 minute until fragrant.
Pour in 6 cups water or vegetable stock and bring to a boil. Season with salt and pepper. Reduce heat to low and simmer, uncovered, for 30–35 minutes or until the broth reduces by about 1 cup. You should have enough broth to serve approximately 1¼ cups broth with 3 ravioli. Adjust the heat as needed to prevent the broth from reducing too quickly.
Taste the broth and adjust the seasonings as needed. If you want the broth to be extra rich, add a pat of plant-based butter right before turning off the heat.
Cook the ravioli:
Bring a large pot of salted water to a boil. Cook the ravioli according to package instructions and then drain. Divide the ravioli between four bowls.
To serve:
Ladle the hot fennel-ginger broth over each bowl of ravioli. Garnish with sliced scallions on top. Enjoy!
