Pressure Release & Finishing Touches
Once cooking is complete:
- Allow a 5-minute natural release, then switch to Quick Release to let out the remaining pressure.
- Carefully remove the lid, transfer everything to a large serving dish, and drizzle with melted butter.
Quick Tips for Success
- Don’t overcook seafood – layering seafood at the top prevents direct steam contact.
- Use shell-on shrimp for more flavor.
- Add spice gradually—Old Bay and Cajun seasoning can both be salty depending on the brand.
