Pro Tips

• For the most tender results, be careful not to overcook the lobster. A quick sear followed by a short pressure cook time is all you need.
• Deglazing the pot with fish stock after searing is crucial. It lifts all the flavorful browned bits from the bottom, adding incredible depth to the stew.
• Stir the heavy cream in at the very end with the pot on the ‘Keep Warm’ setting. Boiling the cream can cause it to separate or curdle.
• Serve this rich stew with a side of crusty bread or garlic toast for dipping into the luscious, creamy broth.

FAQ

Q: Can I use frozen lobster tails for this recipe
A: For the best results, this recipe requires defrosted lobster tails. Thawing them completely before you begin ensures they sear properly and cook evenly in the short pressure cooking time.

Q: What should I serve with this lobster stew
A: This rich stew pairs perfectly with crusty bread or garlic toast. They are ideal for dipping into the luscious, creamy tomato broth to soak up every last drop.
