Craving a taste of the sea without spending hours by the stove? This Instant Pot Seafood Stew is your answer! It delivers all the rich, rustic flavor of a classic coastal cioppino but comes together in just 35 minutes. We’re talking tender octopus, plump shrimp, and delicate shellfish swimming in a savory tomato and garlic broth. It’s the perfect, soul-warming meal for a busy weeknight when you need something special, fast.

Ingredients

• 1 lb or 450g octopus, chopped
• ½ lb or 225g shelled mussels
• ½ lb or 225g shelled clams
• ¼ lb or 115g shrimp, peeled and deveined
• 1 cup or 240ml low-sodium fish stock
• 2 cups or 480ml tomato passata
• 2 onions, roughly chopped
• 3 cloves garlic, minced
• 1 tbsp olive oil
• Salt and freshly ground black pepper, to taste

Instructions

1. Set your Instant Pot to the “Sauté” function and add the olive oil. Once shimmering, add the chopped onions and cook until they begin to soften, about 3-4 minutes.
2. Stir in the minced garlic and cook for one more minute until fragrant.
3. Pour in the fish stock and tomato passata. Use a wooden spoon to scrape any browned bits from the bottom of the pot. Season with salt and pepper.
4. Add the chopped octopus, shelled mussels, shelled clams, and shrimp to the pot, stirring gently to submerge everything in the liquid.
5. Secure the lid, ensure the steam valve is set to “Sealing,” and select the “Meat/Stew” function. Set the timer for 10 minutes.
6. Once the cooking cycle is complete, perform a quick pressure release. Carefully open the lid, give the stew a final stir, and serve hot.
