how to store Italian Penicillin Soup
Cool the soup to room temperature within two hours. Put it in airtight containers and refrigerate for up to 4 days. For longer storage, freeze in freezer-safe containers for up to 3 months.

tips to make Italian Penicillin Soup
- Use bone-in chicken for the best flavor.
- Keep the pot at a gentle simmer to make the broth clear.

variation (if any)
- Make it vegan: use vegetable broth, remove the chicken, and add white beans or shredded king oyster mushrooms for texture.
- Add greens: stir in baby spinach or kale at the end until wilted.
- Use different pasta: orzo or small shells work well.
- Add more heat: increase red pepper flakes to taste.
FAQs
Q: Can I use cooked chicken instead of cooking a raw breast in the broth?
A: Yes. If you use cooked chicken, add it after the pasta cooks and warm it for a few minutes so it does not dry out.
Q: Can I skip the lemon?
A: You can, but lemon gives the soup its bright finish. Try a little lemon at first and add more if you like.
Q: How do I keep the pasta from getting too soft when I store leftovers?
A: Cook the pasta a bit less than package time so it stays firmer after storing. Or store the pasta separately from the broth and combine when reheating.
Q: Can I use boneless, skinless chicken breast?
A: Yes, but the broth will have less depth. You can brown the chicken first or add a bit more seasoning to boost flavor.
Q: Is this soup good for children and the elderly?
A: Yes. The small pasta and soft chicken make it easy to eat. Reduce the red pepper flakes for milder flavor.
