Set a large soup pot over medium-high heat and add the olive oil. Add the onion, carrots, celery, and kohlrabi. Cook for about 5 minutes, stirring often, until the vegetables begin to soften.
Stir in the garlic, ginger, rosemary, thyme, bay leaves, salt, and pepper. Cook for about 1 minute, just until fragrant.
Pour in the broth, white wine, and lemon juice. Stir to combine. Bring to a boil, then reduce the heat to low, cover, and simmer for 20 minutes.
Stir in the fusilli noodles and continue cooking, uncovered, for about 20 minutes, stirring occasionally, until the pasta is tender.
Remove the bay leaves. Ladle into bowls and serve warm.
