Common Mistakes & How to Avoid Them

Common Mistake	What Happens	The Easy Fix
Skipping Deglazing	Browned meat bits trigger the Instant Pot “Burn” signal.	Scrape the bottom of the pot with broth right after sautéing.
Using Pre-Cooked Rice	Rice turns overly soft and mushy during pressure cooking.	Use uncooked long-grain white rice or stir pre-cooked rice in at the end.
Quick Releasing Immediately	Starch from the rice foams and splatters through the steam valve.	Allow a 10-minute natural pressure release before opening the valve.

Storage & Reheating Guidelines

Refrigeration: Store cooled leftover soup in an airtight container in the fridge for up to 4 days.
Note on Rice Absorption: Rice will continue to absorb broth as it sits in the fridge. Add 1/2 to 1 cup of warm beef broth or water when reheating on the stovetop or in the microwave.
Freezing Option: For long-term meal prep, freeze the soup base without the rice for up to 3 months. Stir fresh cooked rice into individual bowls after reheating.
