This spicy aromatic Easy Fish Stew with Red Lentil is gluten and dairy free and makes a healthy and delicious weeknight dinner idea.
Friday night is fish night (not always, but today it is) and I have cooked a fiery, rich dish I’ve been thinking about making all week. Easy Fish Stew with Red Lentil. It contains popular Asian ingredients, such as ginger and coconut milk (and oil) but is not based on any specific recipe. It is simply a combination of ingredients I’ve been craving (all week) which together are rather delicious. I hope you’ll agree.
How to make easy fish stew
Don’t you just love it when you can whip up something delicious in less than 30 minutes? I do. Especially when it can feed a family. Fish cooks very quickly and the entire dish (including preparation time) is ready in under 30 minutes!
And while the stew is bubbling away you’ll have enough time to prepare some fluffy basmati rice to go with it. How is that for a quick weeknight dinner idea?
To make the stew start by briefly frying the ginger, garlic, chilli and onion in the coconut oil. Then add the red lentils and continue cooking for another minute or so. Add the rest of the ingredients (not the fish), cover and simmer for about 15 minutes stirring occasionally.
When to add the fish into the stew
As fish cooks very quickly it gets added to the stew in the last 2 minutes of cooking. After you’ve turned off the heat let it stand, covered, for about 3 more minutes before serving. Overcooking the fish might make it tough and stringy, but do ensure it is cooked through before you serve it.
What fish to use
You can use any white fish to make this easy stew recipe, so just use whatever is easiest to get where you live. (I used cod but haddock, pollock or hake would be fine too). Frozen fish is fine too, only let it thaw completely first and remove any excess water. You can refrigerate it overnight to defrost slowly.
Fish stew with tarragon
I think tarragon goes extremely well with fish. I’ve used it before in my Spicy Fish Wraps recipe as well as this Fish Pie with Avocado and Tarragon. It is so fragrant and really complements the coconut and ginger in the stew. So apart from some chilli for a bit of heat you don’t need much else to make this delicious red lentil fish dish.
Enjoy!
