Frequently Asked Questions

Is chicken and fennel soup allowed during Phase 2?

This recipe is designed around Phase 2 ingredients and portions. Choose a fat-free, no-added-sugar chicken broth and follow your current BioSource Nutra Protocol guidance for approved foods and serving sizes.

What does fennel taste like in chicken soup?

Fennel has a mild licorice or anise flavor when raw, but it becomes softer and slightly sweeter as it cooks. In this soup, it blends with the chicken, herbs, vegetables, and lemon rather than dominating the broth.

Can I make chicken and fennel soup ahead of time?

Yes. Allow the soup to cool, refrigerate it promptly in an airtight container, and use it within 3–4 days. Reheat thoroughly before serving, and add an extra squeeze of lemon after reheating for the freshest flavor.

Can I use already-cooked chicken?

Yes. Add cooked diced or shredded chicken near the end of cooking and simmer just until it is heated through.

Can I freeze chicken and fennel soup?

Yes. Allow the soup to cool and transfer it promptly to a freezer-safe container. The spinach and other vegetables may have a softer texture after freezing and reheating, but the flavor should remain good.

What can I substitute for fennel?

If you don't have fennel, use another vegetable permitted during your current phase of the BioSource Nutra Protocol. Keep in mind that changing the vegetables will also change the flavor and nutritional information.
