6. Serve & Garnish

Pro Tips for the Best Soup
✔ Pasta perfection: Undercook pasta slightly—it softens more in hot broth.
✔ Spice control: Start with 1 tbsp Cajun seasoning, then add more.
✔ Cream separation fix: Temper cream with a bit of hot broth before adding.
✔ Thicker soup: Mix 1 tbsp cornstarch with 2 tbsp water, stir in at the end.
Variations & Adaptations
🍗 Seafood version: Swap chicken for shrimp or crawfish.
🌱 Vegetarian: Use mushrooms and veggie broth, omit chicken.
🥛 Lighter option: Substitute heavy cream with coconut milk or evaporated milk.
🍝 Gluten-free: Use GF pasta and check Cajun seasoning for additives.
Serving Suggestions
- With crusty bread (for dipping)
- Side salad (Caesar or simple greens)

Storage & Reheating
- Fridge: Keeps for 3-4 days (soup thickens—add broth when reheating).
