Ingredients

Servings:
4
Units:

Aromatics & Base

  • 15 ml Olive oil

    For sautéing vegetables on stovetop before slow cooker

  • 1 medium Onion, chopped
  • 120 g Celery, sliced
  • 1 whole Hot pepper, finely chopped
  • 4 cloves Garlic cloves
    , finely chopped

    Added after onion and celery have started softening

  • 30 g Tomato paste

    Caramelise with vegetables before slow cooking

Liquids & Seasonings

  • 240 ml White wine

    Used to deglaze pan on stovetop; alcohol reduces during initial sauté

  • 1 whole Bay leaf

    Remove before serving

  • 15 ml Dried oregano
  • 5 ml Dried thyme
  • 5 ml Dried basil
  • 3 ml Red pepper flakes(optional)

    Add if you prefer extra heat

  • 390 g Diced tomatoes (tinned)
  • 240 ml Chicken stock

    Any quality broth works; fish or vegetable stock also suitable

  • 1 ÂĽ litre Water

    Reduced from 2 cups (original) to account for slow cooker moisture retention. Substitute 240 ml clam juice for one portion if desired for deeper seafood flavour.

Seafood & Finishing

  • 450 g Mixed seafood, prepared (shelled/deveined as needed)

    Add in final 20–30 minutes on High or final 45 minutes on Low to prevent overcooking

    Can include prawns, mussels, clams, squid, firm white fish or any combination

  • 30 ml Lemon juice

    Stir in during final 10 minutes for freshness

  • to taste Salt and black pepper

    Season throughout cooking and adjust at the end

Method

  1. 1

    Heat olive oil in a large frying pan over medium heat. Add the chopped onion, sliced celery, and hot pepper. Cook for 1 minute to give them a head start.

    ~1 min
  2. 2

    Add the finely chopped garlic and a pinch of salt. Continue cooking until the onion begins to soften, about 3–4 minutes.

    ~4 mins
  3. 3

    Stir in the tomato paste. Using the back of a spoon, spread it around the bottom of the pan and let it cook for 1–2 minutes. It's fine if the paste sticks slightly to the pan.

    ~2 mins

    Tip: This caramelisation builds deeper flavour

  4. 4

    Pour in the white wine and stir well, scraping up any browned bits from the bottom of the pan (deglazing). This will lift the caramelised flavours into the liquid.

    ~1 min
  5. 5

    Add the bay leaf, dried oregano, dried thyme, dried basil, and red pepper flakes (if using). Stir and let the mixture simmer on the stovetop for 5 minutes to concentrate the flavours and reduce the wine slightly.

    ~5 mins
  6. 6

    Add the tinned diced tomatoes, chicken stock, and water (or with clam juice substitution if preferred). Stir well.

    ~2 mins
  7. 7

    Transfer the entire contents of the frying pan to your slow cooker. Stir gently to combine. Cover and cook on Low for 5–5.5 hours, or on High for 2.5–3 hours.

    ~5 hrs 30 mins

    Tip: At this point, you've achieved the base broth with excellent depth of flavour

  8. 8

    If cooking on Low, switch to High setting. If already on High, keep it there. Add the prepared mixed seafood, stirring gently to distribute evenly throughout the stew.

    ~1 min
  9. 9

    Cover and continue cooking for a further 20–30 minutes on High (or 45 minutes on Low if you prefer), until the seafood is cooked through but not rubbery. Prawns and firm fish should be opaque; mussels and clams should have opened.

    ~25 mins

    Tip: Check at 20 minutes—seafood cooks quickly

  10. 10

    Stir in the lemon juice during the final 10 minutes of cooking. Taste and adjust seasoning with salt and black pepper as needed.

    ~1 min
  11. 11

    Remove the bay leaf before serving. Ladle the stew into bowls and serve whilst hot.

    ~5 mins

    Tip: Serve with crusty bread, a simple salad, or over rice

Frequently Asked Questions

Yes, absolutely. You can sauté the aromatic base on the stovetop (steps 1–5) up to 24 hours ahead, then refrigerate it. Transfer it to your slow cooker when you're ready to cook. However, always add the seafood during the final 20–30 minutes of cooking on High, never in advance, to prevent overcooking
