Ingredients

• 7 oz / 200g trout fillets, chopped into bite-sized pieces
• 7 oz / 200g cod fillets, chopped into bite-sized pieces
• 2 cups / 450g shrimp, cleaned and deveined
• 1 ½ cups / 300g tomatoes, chopped
• 2 spring onions, finely chopped
• 1 small green bell pepper, chopped
• 3 garlic cloves, crushed
• 2 cups / 480ml fish stock
• 3 tbsp / 45ml extra virgin olive oil
• Spices
• 2 bay leaves
• 1 tsp / 5g sea salt
• ½ tsp / 1g black pepper, freshly ground

Instructions

1. Directions
2. Set your Instant Pot to the ‘Sauté’ function. Once hot, add the olive oil, followed by the chopped spring onions, bell pepper, crushed garlic, and bay leaves. Sauté for 5 minutes, stirring occasionally, until the vegetables are fragrant and softened.
3. Gently add the trout, cod, and shrimp to the pot. Stir carefully and cook for another 2-3 minutes, just until the shrimp begin to turn pink. Pour in the fish stock and chopped tomatoes.
4. Season with sea salt and freshly ground black pepper, stirring gently to combine all the .
5. Secure the lid on the Instant Pot and set the steam release handle to the ‘Sealing’ position. Select ‘Manual’ or ‘Pressure Cook’ and set the timer for 5 minutes on high pressure.
6. Once the cooking cycle is complete, allow the pressure to release naturally for 10 minutes before performing a quick release for any remaining pressure. This prevents the delicate fish from breaking apart.
7. Carefully open the lid, remove the bay leaves, and give the stew a final gentle stir. Ladle into bowls and serve immediately, perhaps with a side of crusty bread to soak up the delicious broth.
