Warm 2 tablespoons (30 ml) olive oil in a pot over medium heat. Add fennel and onion with a pinch of salt and cook, stirring, until tender and lightly golden, 8–10 minutes.
Stir in garlic and red pepper flakes; cook 30 seconds. Add tomato paste and cook until darkened slightly, 1 minute.
Pour in white wine, scraping up any browned bits; simmer until reduced by about half, 2–3 minutes.
Add crushed tomatoes, stock, saffron, orange peel, thyme, and bay leaf. Bring to a gentle simmer and cook uncovered 15–20 minutes to meld flavors.
Discard thyme, bay, and orange peel. Season with salt and black pepper, then stir in lemon juice to brighten.
Ladle into warm bowls and finish with a drizzle of olive oil and a sprinkle of chopped parsley and reserved fennel fronds.
