What is good about tuna salad with red onion

A step-by-step guide to tuna salad with red onion

Step 1
Prepare ingredients: Drain the liquid from the tuna cans and place the fish into a medium mixing bowl. Peel the red onion and chop it into very small pieces with a sharp knife. Squeeze the lemon to get the required amount of fresh juice for the dressing.
Step 2
Flake the fish: Use a fork to break the tuna into smaller flakes inside the bowl. Ensure there are no large chunks left so the texture remains consistent. This makes it easier to mix with the other ingredients later.
Step 3
Mix the base: Add the chopped red onion, mayonnaise, lemon juice and dried dill to the bowl. Stir everything together with a spoon until the fish is evenly coated. Make sure the onion is distributed throughout the tuna salad with red onion.
Step 4
Season and serve: Add the salt and black pepper to the bowl and give it one final stir. Taste the salad to see if it needs any more seasoning. Serve the mixture immediately or store it in an airtight container in the fridge.

The best tips for tuna salad with red onion

For the best texture, make sure to drain the tuna very well before starting. Excess liquid can make the dressing too thin and watery. If you prefer a lighter version, you can replace half of the mayonnaise with Greek yoghurt. This tuna salad with red onion tastes even better if you let it sit for ten minutes to allow the flavours to meld together.

You can also add extra crunch by mixing in some chopped celery or cucumber. Always use fresh lemon juice instead of bottled juice for a cleaner taste. If the onion is too strong, soak the chopped pieces in cold water for five minutes then pat them dry. This removes some of the sharp bite while keeping the crunch.
