Fresh Cajun Spiced Fish with Green Goddess Dressing

 

There are some dinners that come together with very little fuss but still offer something bright and nourishing at the end of a long day. Cajun Spiced Fish with Green Goddess Dressing is one of those meals. It’s a flavour-forward dish that relies on simple pantry ingredients, fresh herbs and a quick pan-fry of the fish. Nothing complicated, not too much to shop for — just beautiful ingredients doing what they do best.

I’ve made this dish many times now, and every time I return to it, I’m reminded of how versatile it is. You can use almost any firm white fish: flathead, rockling, snapper, barramundi — whatever looks freshest and most appealing when you’re market shopping. The Cajun spice brings warmth and depth without overpowering the fish, and the cornflour adds a light crispness that sits beautifully against the cool, creamy green goddess dressing.

Why I Love Making Fresh Cajun Spiced Fish with Green Goddess Dressing

If you’ve never made the dressing before, you’re in for a treat. It’s essentially a bright blend of herbs, garlic, lemon juice and whole-egg mayonnaise. I add coriander and either mint or dill, depending on what’s in the fridge or garden, and it always tastes fresh and lively. Once it’s blitzed, it becomes a silky green drizzle that seems to improve almost anything it touches. I often make a double batch because it’s wonderful spooned over grilled vegetables, poached eggs, tucked into sandwiches, or thinned out slightly and used as a dressing for crunchy salads.

What I love most about Cajun Spiced Fish with Green Goddess Dressing is the contrast of textures. The fish, lightly coated and pan-fried in a little butter and olive oil, takes on a beautiful golden crust. Then comes the cool, herbaceous dressing. Finally, a generous scattering of toasted slivered almonds brings the crunch that makes the whole dish come alive. The almonds might look like a small addition, but they completely elevate the experience.

In the cooking club and throughout my classes, I always encourage people to think about balance — not just flavour, but texture. Here, the crunch of the almonds, the crisp edges of the fish, and the creamy dressing work together in a way that feels just right. It’s simple, yes, but it’s also thoughtful.

This recipe is also a great one to make your own. Serve it over rice pilaf if you want something substantial. Spoon it over brown basmati with a squeeze of lemon. Add a crisp cabbage slaw on the side for freshness, or pile everything into warm tortillas for a relaxed dinner. The components are flexible, and that’s part of the joy. If you happen to have leftover green goddess dressing the next day, consider it a small gift to yourself.

Another lovely element of this dish is how achievable it is on a weeknight. The fish cooks in minutes, the dressing whizzes through the blender, and the nuts toast while everything else comes together. When people ask for meals that are quick but still deeply satisfying, this is one I often point them toward. And for those who like to make their own spice blends, a homemade Cajun mix is incredibly easy — paprika, garlic and onion powder, oregano, thyme, cayenne and black pepper. A small jar lasts for months and adds excitement to so many simple meals. Here is a link to a Good Food recipe for you for a homemade Cajun spice mix.

Fresh Cajun Spiced Fish with Green Goddess Dressing is lively and full of character. It sits comfortably at the family table but would be just as welcome when friends are over. Beautiful food doesn’t need to be complicated or time-consuming; it simply needs to be cooked with intention and enjoyed with people you care about.

If you make this one, I hope it becomes a regular visitor to your table. And if you’re part of the Relish Mama Cooking Club, you’ll already know how much I love sharing meals like this — food that nourishes us, brings us together and makes even the simplest evenings feel that bit more special.

Equipment

  • A blender or small food processor
  • 2 large frying pans (or cook in batches with one pan)
  • A shallow bowl for dredging
  • Tongs or a fish spatula
  • A small frying pan for toasting almonds
  • A serving platter

Ingredients

Cajun Spiced Fish

  • 700 g boneless

    skinless white fish fillets, cut into large pieces


  • 1/4 cup Cajun spice mix
  • 1/4 cup cornflour
  • 1/2 teaspoon sea salt
  • Unsalted butter and olive oil , for cooking

Green Goddess Dressing

  • ½ cup

    flat-leaf parsley


    crushed


  • 1/2 cup

    coriander


  • 1/2 cup

    mint or dill


  • 1 clove garlic
  • 1/2 lemon zested and juiced
  • 100 g whole-egg mayonnaise
  • 2 tablespoons Greek yoghurt

To Serve

  • ½ cup

    toasted slivered almonds

Steamed rice

  • Extra chopped parsley or coriander
  • Steamed rice or rice pilaf, slaw or warm tortillas

Instructions

Make the Green Goddess Dressing

  • Place the parsley, coriander, mint or dill, garlic, lemon juice & zest, mayonnaise & yoghurt into a blender or food processor.
Blend until smooth and vibrant green.
Taste and adjust the lemon or seasoning as needed.
Cover and refrigerate until serving.

Prepare the Fish

  • Place the Cajun spice, cornflour and salt (if using) into a shallow bowl.
Mix well, then season with cracked black pepper.
Add the fish pieces and turn to coat, shaking off any excess.

Cook the Fish

  • Heat two large frying pans over medium-high heat.
Add a good splash of olive oil and a knob of butter to each pan.
When the butter foams, add the fish in a single layer.
Cook for 2–3 minutes on each side, or until golden, crisp and just cooked through.
Transfer to a warm serving platter.

To Serve

  • Generously spoon the Green Goddess dressing over the fish.
Scatter with toasted slivered almonds and fresh herbs.
Serve with rice, slaw or tortillas — whatever makes it a beautiful meal for you.

Notes

Choose firm white fish that holds shape well when pan-fried: flathead, ling, rockling, snapper, barramundi or basa all work nicely.
Cajun spice blends vary in heat and saltiness. Taste your blend and adjust added salt accordingly.
Toast the slivered almonds until deep golden for the best flavour and crunch.
The Green Goddess dressing can be made ahead and kept in the fridge for up to 3 days.
If you prefer a lighter dressing, replace 2 tablespoons of the mayonnaise with Greek yoghurt or add the zest of ½ lemon for extra brightness.
Serve with red rice pilaf, brown basmati, a crisp slaw, or warm tortillas for a more relaxed meal.
Leftover dressing is beautiful over grilled vegetables or stirred through a simple salad the next day.
