How to Make Tuna Mousse
You can whip up this extremely easy tuna mousse recipe in 5 minutes! Simply combine all ingredients and blend. You can use a food processor, blender or use an immersion blender to mix the tuna to a smooth paste.
This Italian tuna salad recipe is simple, so it’s important that you choose quality ingredients!
Use Quality Yellowfin Tuna!
There are BIG differences between canned tuna brands. If it looks and smells like cat food, don’t use it! We recommend looking for tuna in glass jars (which tend to be of higher quality) or selecting canned tuna that specifically says it contains tuna filets.
Here is a link [affiliate] to Tonnino Tuna, a brand we like and use often. It is more expensive than low-quality canned tuna, but less expensive than tuna filets in a jar. We think it’s a great value!
Raw onions bother your stomach?
Try microwaving the onion pieces with a bit of olive oil for a minute or two before adding them to the tuna mousse. Cooked onions will still be delicious in this tuna mousse recipe and may help digestion.
Serve with roasted red peppers!
Serve inside rolled-up roasted red peppers, or use as a spread on toast points or ‘tramezzini’ (white, crustless bread slices). If used as a tramezzino sandwich filling, the sandwiches are usually cut into triangles to serve.
