👩🏽‍🍳 How to Make a Creamy Mackerel Rillettes Sandwich

Mash the Mackerel

Start by draining your tin of mackerel and placing the fish into a clean mixing bowl. Using a fork, gently mash it down — take your time here. You want the fish to break down completely so there are no big chunks left. The goal is a soft, creamy base that will mix easily with the other ingredients.
I like to mash it until it almost looks like a soft spread. If your mackerel has bones, they’ll usually be soft and mashable too — but feel free to remove any tougher bits if you prefer.

Add the Fresh Veggies

Now it’s time to bring in that freshness! Add your chopped onion, diced cucumber, shredded lettuce, and chopped tomato into the bowl.
These add crunch, color, and a fresh bite that balances out the richness of the mackerel. Mix everything gently so the veggies are evenly combined without breaking them up too much. It should already look vibrant and full of texture.

Cream It Up

Once your veggies and fish are mixed, it’s time to make it creamy. Add 1–2 tablespoons of mayonnaise and a little ketchup. Start with a small amount and mix — you can always add more if needed. The mayo gives it a rich, smooth feel, and the ketchup adds just a touch of sweetness and tang.
Fold it all together gently with a fork or spatula. You want it to hold together like a soft, spreadable mixture. At this point, taste it and adjust the seasoning. Add salt to bring out the flavors, and if you like a little kick, sprinkle in some black pepper or grate a bit of lemon zest for brightness.

Build the Sandwich

Now comes the fun part — building your sandwich. Grab your favorite bread — whether it’s a baguette, sourdough, or regular sliced bread — and spread the mackerel mixture generously on one side.
If you want extra crunch and color, feel free to layer on a few fresh slices of cucumber, lettuce, or even tomato. Then place the other slice of bread on top and press gently.
This sandwich already smells so good — fresh, creamy, and comforting.

Cut and Serve

Use a clean, sharp knife to cut your sandwich in half or into bite-sized pieces if you’re serving it as a snack or party finger food. Arrange them nicely on a plate — maybe with some salad or cucumber slices on the side — and enjoy every bite.
No fuss, no frying, just good food made simple.
