This aromatic Low Fat Fish Pie with Avocado & Tarragon is a delicious, healthy and super easy to put together dinner idea.
I am always happy when I come up with a new idea that works. Such as this Low Fat Fish Pie with Avocado & Tarragon. Fish pie is a well-known, popular dish, of course, but fish pie with avocado isn’t. Yes, I’ve actually added the avocado into the pie. And baked it.
I am a huge fan of avocado and have used it in many of my recipes, but always in its raw form. This is the first time that I’ve used it in a recipe that is cooked. I had some avocados on my windowsill that just wouldn’t ripen. Sometimes they don’t, even if the package says ‘ripen at home’! These avocadoes couldn’t really be eaten raw so I thought why not cook them!
I’ve had grilled avocados and deep fried avocados before and really enjoyed them too! This gave me the confidence to go ahead with my new recipe idea. And it worked!
Low fat fish pie
This pie recipe contains moderate amounts of cheese and butter. It’s rich and creamy though I used semi-skimmed milk (low fat milk) rather than full fat milk or cream. The sauce also contains a small amount of cream cheese for extra creaminess and a tangy flavour.
How to make low fat fish pie with avocado
This fish pie recipe is very uncomplicated and takes less than an hour to make (including boiling the potatoes). While you are waiting for the potatoes to boil prepare the sauce.
Heat up the butter, add the flour and whisk until smooth. Then add the milk, mustard and cream cheese whisking all the time until the sauce thickens. Remove from the heat, add half of the cheddar, tarragon, onion granules, lemon juice and season to taste. The sauce won’t take more than 10 minutes to make.
Once you’ve mashed the potatoes your pie is ready to assemble.
Place fish chunks in your oven dish, scatter over the chopped avocado and pour in the sauce (reserving 3 tablespoons). Then simply cover with a layer of mashed potatoes, drizzle the remaining sauce, scatter the rest of the cheese over the top and bake for 40 minutes!
Things to remember when making this fish pie recipe
Make sure you use avocados that are firm and not quite ripe. It is also important to use a generous amount of seasoning in this recipe, as the main ingredients, i.e. fish, potatoes and avocado, are quite bland. Be generous with the pepper especially! I like to use white pepper in fish dishes but black pepper is fine too. And then there is the sauce, which should be sharp and peppery, so adjust the amount of mustard, lemon juice and pepper according to your preference.

Fish and tarragon
I used tarragon in this healthy fish pie recipe because I think it pairs extremely well with fish, but fresh parsley or dill will work well too.
