Method

  1. 1

    Heat the olive oil in a large frying pan over medium heat. Add the diced onion and cook for 3–4 minutes, stirring occasionally, until softened and translucent.

    ~5 mins

    Tip: This initial sauté builds flavour for the slow cooker base

  2. 2

    Add the minced garlic to the pan and cook for 1 minute until fragrant, stirring constantly.

    ~2 mins
  3. 3

    Stir in the canned chopped tomatoes and cook for 2–3 minutes, breaking them down slightly with the spoon.

    ~3 mins
  4. 4

    Transfer the cooked tomato mixture to your slow cooker. Add the vegetable or fish stock, oregano, basil, salt, and black pepper. Stir well to combine.

    ~5 mins

    Tip: Reduced stock quantity prevents watery results in the slow cooker

  5. 5

    Cover the slow cooker and cook on Low for 4–5 hours or on High for 2–2.5 hours.

    ~4 hrs 30 mins

    Tip: This allows the tomato base to develop depth of flavour

  6. 6

    After the base has cooked, prepare your seafood: cut the fish into chunks, peel and devein the prawns, and clean the mussels or clams (discard any that don't close when tapped).

    ~10 mins

    Tip: Prepare seafood just before adding to prevent drying out

  7. 7

    Switch the slow cooker to High if it wasn't already on that setting. Add the fish chunks and prawns to the stew, stirring gently to submerge them.

    ~2 mins
  8. 8

    Cover and cook on High for 30 minutes.

    ~30 mins

    Tip: Fish and prawns cook quickly; avoid overcooking

  9. 9

    If using mussels, clams, or scallops, add them now (they cook faster). Cover and cook for a further 15–20 minutes until the mussels and clams have opened and the scallops are just cooked through. Discard any mussels or clams that fail to open.

    ~20 mins
    Optional step

    Tip: These delicate shellfish require minimal cooking time

  10. 10

    Taste the stew and adjust the seasoning with additional salt and pepper if needed.

    ~2 mins
  11. 11

    Ladle the stew into bowls and garnish generously with fresh chopped parsley and torn basil.

    ~5 mins

    Tip: Fresh herbs add brightness and aroma

  12. 12

    Serve immediately with crusty bread for soaking up the delicious tomato broth.

Frequently Asked Questions

Yes, you can use frozen fish and prawns, but thaw them completely first and pat them dry with kitchen paper to remove excess moisture. Frozen mussels and clams should also be thawed before adding. This prevents the stew from becoming watery and ensures even cooking
