TL;DR: This classic tuna macaroni salad recipe stays creamy, never mushy, and feeds a crowd. The secret is slightly undercooking the pasta, rinsing it well, and using inexpensive flaked tuna with a little of its liquid left behind.
If there is one salad that shows up at every Canadian summer gathering, it is tuna macaroni salad.
We see it at potlucks and at the campground. We see it at family reunions and of course beside burgers at backyard BBQs. In a recent podcast, Kirstie even talks about how she loves it as a midnight snack after a few beverages!
As Red Seal chefs, we love complicated projects as much as the next cook. We have spent days making ramen broth and laminated dough. But sometimes the simplest recipes are the ones people remember most.
This classic tuna macaroni salad recipe is one of them.
The best classic tuna macaroni salad combines properly cooked pasta, flaked tuna, crunchy celery, and enough mayonnaise to keep everything creamy after chilling.
Most versions fail for one reason. The pasta is overcooked.
Pasta continues to absorb moisture after cooking. If you boil it until perfectly tender, then mix it with dressing and refrigerate it, you often end up with a bowl of mush.
We cook our pasta about about 2 minutes less than the package directions. Then we rinse it thoroughly under cold water. This stops the cooking immediately and gives you a much better texture the next day.
The second trick is the tuna.
Forget the expensive solid white tuna. Save your money. We use inexpensive flaked tuna and leave a little of the liquid behind. That liquid adds flavour and helps keep the salad moist.
Slightly undercooked pasta absorbs dressing without falling apart.
Rinsing stops the cooking process and cools the pasta quickly.
The celery provides crunch and freshness.
The tuna liquid adds flavour and moisture.
The mayonnaise coats every piece of pasta and creates the creamy texture everyone expects from a classic macaroni salad.
This is not fancy food. This is dependable food. Sometimes that is exactly what you need. We bet you’ve already got the water on for the pasta while reading this blog!

Want to make it your own? Try adding:
We keep ours simple because that is how we grew up eating it.
Avoid overcooking the pasta. This is the number one mistake.
Avoid skimping on the mayonnaise. Pasta absorbs dressing as it sits.
Avoid adding too many ingredients. Tuna macaroni salad is at its best when it stays simple.
Store covered in the refrigerator for up to 3 days.
If the salad seems dry after chilling overnight, stir in an extra spoonful of mayonnaise before serving.
Rinsing stops the cooking process and cools the pasta quickly. This prevents the pasta from becoming overcooked and mushy.
Yes. In fact, we recommend it. The flavour improves after a few hours in the refrigerator.
We prefer inexpensive flaked tuna. It mixes evenly throughout the salad and provides plenty of flavour.
No. The mayonnaise will separate and the texture will suffer after thawing.
