Level Up Your Tuna Melts with Dill
One pinch of dill turns a tuna melt from good to 'what IS that?'
Tuna melts are already doing a lot right — creamy, salty, melty — but they can taste a little flat once the cheese takes over. Dried dill cuts through that richness with a bright, grassy sharpness that makes every bite taste cleaner and more distinct, without announcing itself loudly enough for anyone to name it right away. The real shift happens in the tuna salad itself, before anything hits the pan. Dill has a natural affinity for fish because its flavor compounds mirror and amplify the briny, ocean-forward notes already in the tuna. The result is a sandwich that tastes more like itself — more tuna-forward, less mayonnaise-heavy — with the melted cheese acting as a smooth backdrop instead of the whole show.
How much
1 teaspoon dried dill (or 1 tablespoon fresh, chopped) for a 4-sandwich batch using two 5-oz cans of tuna
When to add it
Stir the dill into the tuna salad mixture before assembling the sandwiches and let it sit for at least 5 minutes. That short rest lets the dried herb rehydrate in the mayo and release its full flavor rather than tasting dusty or raw.
Why it works
What you need
- Two 5-oz cans tuna in water, drained well
- 3 tablespoons mayonnaise
- 1 tablespoon Dijon mustard
- 2 celery stalks, finely diced
- 2 tablespoons red onion, finely diced
- 1 teaspoon dried dill (or 1 tablespoon fresh dill, chopped)
- Salt and black pepper to taste
- 8 slices sturdy sandwich bread (sourdough or rye work great)
- 4 slices sharp cheddar or Swiss cheese
- 2 tablespoons butter, softened
How to do it
- 1
Drain tuna thoroughly, pressing out excess water with the back of a spoon — dry tuna means the salad won't turn watery on the bread.
- 2
In a bowl, combine tuna, mayonnaise, Dijon, celery, red onion, and dill. Season with salt and pepper. Stir until evenly mixed.
- 3
Let the tuna mixture sit uncovered for 5 minutes — you'll notice the dill smell shift from sharp to rounded as it hydrates.
- 4
Butter one side of each bread slice. Place 4 slices butter-side down in a cold skillet, then turn the heat to medium — starting cold gives an even, golden crust without burning.
- 5
Spoon the tuna mixture evenly onto the bread in the skillet (about ½ cup per sandwich), then lay one slice of cheese over each.
- 6
Top with the remaining bread slices, butter-side up. Cook 3–4 minutes until the bottom is deep golden, then flip carefully and cook another 2–3 minutes until the cheese is fully melted and the second side matches.
- 7
Transfer to a cutting board, let rest 1 minute, then cut and serve — the rest keeps the filling from spilling out immediately.
Same trick, another dish: The same dill-in-the-mix trick works perfectly in egg salad sandwiches, where it does the same job of brightening a rich, mayo-heavy filling.
