Smoked trout dip is a classic British appetizer recipe that is incredibly easy to make. Some dishes are so darn simple, I sometimes can’t believe they aren’t more popular.

This smoked trout dip is one of those dishes. I got the recipe over 35 years ago when I was traveling through England after college.

I stayed with friends of my mom. For dinner one night, we each were served a small ramekin of this creamy smoked trout dip, which is more like a mousse, with some water biscuits as our starter. I immediately fell in love with the velvety texture and slightly smoky flavor of the fish.

The next day I left for Scotland with the recipe in my backpack! I first published this on September 26th, 2013.  I’ve updated the photos and in the process discovered it’s also low-carb, keto and gluten free.

Smoked trout can be purchased in most local or specialty markets. I found this one at Trader Joe’s.

Smoked fish seems to be much more popular in England and smoked mackerel would work equally well. This is a classic British starter, that’s not much more than butter and a bit of cream. Although it’s generally served with water biscuits or cream crackers, you can pipe it into cucumber cups, or serve it American Style on top of thick-cut potato chips.

When I re-made this smoked trout dip last weekend, I spread some on Trader Joe’s new gluten free crispbread, which are pretty low-carb; only 6 grams for each slice.

How to make smoked trout dip

Remove the skin from the smoked trout and break it into pieces. Pulse the trout a few times in the bowl of a food processor. Add remaining ingredients until mousse is blended and somewhat smooth. Serve with vegetables, water biscuits or low-carb crackers.

    Is this correct? It seems like an awful lot of butter. I want to make it but I’m worried that 4:3 ratio of trout to butter is off.

    1. Did you make it? Yes it’s correct. Not sure why you’ve given me four stars without having made it? It’s a spread that goes on crackers or bread.

      1. I gave you 4 stars because I haven’t tried it yet, should I have left it at zero and then updated it afterwards?

        I wanted to check the recipe was correct so I didn’t waste over a pound of butter if it wasn’t.

        Thanks for the reply, I’ll make it now you confirmed it’s not a mistake

    Oh my goodness! This is sooo easy and was a hit at a little party I had over the weekend. I served it with a combination of regular and gluten free crackers.
