Smoked trout mousse 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 Mousse 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 Smoked Trout Mousse with some water biscuits as our starter. I immediately fell in love with the creamy 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. (As an Amazon affiliate, I may earn a small commission on qualifying purchases.) I’ve updated the photos and in the process discovered it’s also low-carb, keto and gluten free.
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 Smoke Trout Mousse last weekend, I spread some on Trader Joe’s new gluten free crispbread, which are pretty low-carb; only 6 grams for each slice.
I love them, but not everyone has a Trader Joe’s close-by. Scroll to the bottom of this post for a collection of low-carb, gluten-free and keto crackers that I’ve collected from some of my healthy blogger friends. You’ll also find some more delicious appetizer ideas that are low-carb, gluten free and keto friendly. You can purchase smoked trout from Trader Joe’s, Whole Foods or from Amazon. Maybe you’re lucky enough to catch and smoke your own trout? This recipe is for you!
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.
No matter how you serve this Smoked Trout Mousse, it takes just under ten minutes to prepare.
