What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1For the best texture, squeeze the drained tuna in a clean kitchen towel to remove every drop of liquid.
- 2Use a microplane or the finest dice for the red onion so it melds into the salad without overpowering.
- 3Let the bread come to room temperature before buttering for an even, crackling crust.
- 4Grill in a cast-iron skillet over medium-low heat to give the cheese time to melt fully without burning the bread.
- 5Press the sandwich gently with a spatula while grilling to seal the edges and create a more compact, toasty bite.
- 6Make the tuna salad up to a day ahead and refrigerate it in an airtight container to save time.
- 7Serve immediately after slicing — the crispy bread softens quickly as the hot filling steams.
Adapt it for your goals.

Skip the top slice of bread and use only one slice per serving; broil the assembled sandwich under the oven broiler until the cheese is bubbly and browned for a lower-carb, extra-crispy option.

Frequently asked questions
Yes, rye or whole wheat bread work well, but avoid flimsy white bread — it won't hold up to the filling or toasting.
