Method
- 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 minsTip: This initial sauté builds flavour for the slow cooker base
- 2
Add the minced garlic to the pan and cook for 1 minute until fragrant, stirring constantly.
~2 mins - 3
Stir in the canned chopped tomatoes and cook for 2–3 minutes, breaking them down slightly with the spoon.
~3 mins - 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 minsTip: Reduced stock quantity prevents watery results in the slow cooker
- 5
Cover the slow cooker and cook on Low for 4–5 hours or on High for 2–2.5 hours.
~4 hrs 30 minsTip: This allows the tomato base to develop depth of flavour
- 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 minsTip: Prepare seafood just before adding to prevent drying out

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
Cover and cook on High for 30 minutes.
~30 minsTip: Fish and prawns cook quickly; avoid overcooking
- 9Optional step
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 minsTip: These delicate shellfish require minimal cooking time

~2 mins - 11

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
