What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Drain the tuna extremely well by pressing the lid against the flakes; excess water makes the salad soggy.
- 2Chill the salad for at least 15 minutes — this lets the flavors meld and the texture firm up.
- 3Use full-fat mayonnaise for the creamiest, most keto-friendly result; low-fat versions add sugar.
- 4For the best crunch, dice celery, onion, and pickles into uniform, small pieces (about corn-kernel size).
- 5Gently fold the dressing into the tuna with a fork to keep some flaky chunks intact.
- 6Let the salad sit overnight in the fridge — it tastes even better the next day as flavors deepen.
- 7Serve on butter lettuce leaves or inside avocado halves for a satisfying low-carb vessel.
