Ingredient Notes
Choose tuna packed in water for a lighter sandwich, or use tuna in oil for a richer flavor. Drain it thoroughly to keep the bread crisp.
Sharp cheddar melts beautifully and adds classic flavor, but Swiss, Monterey Jack, or American cheese all work well.
Sourdough gives the crispiest texture, while white sandwich bread creates a classic diner-style tuna melt.
Fresh lemon juice brightens the tuna salad and balances the richness of the mayonnaise.
Ingredients
Tuna salad
- 2 cans (5 oz / 142 g each) tuna in water, well drained
- ⅓ cup mayonnaise
- 1 Tbsp Dijon mustard (or yellow mustard)
- 2 Tbsp finely diced celery
- 2 Tbsp finely diced red onion (or green onion)
- 1 Tbsp sweet pickle relish (optional)
- 1 tsp lemon juice
- ¼ tsp garlic powder
- ¼ tsp black pepper
- Pinch of salt, to taste
Sandwiches
- 4 slices sturdy sandwich bread (sourdough, white, or whole wheat)
- 4-6 slices cheddar cheese (or 1 cup shredded)
- 2 Tbsp soft butter, for the outside of the bread
- Optional: tomato slices, dill pickles on the side
Instructions
- Mix the tuna salad. In a bowl, flake the drained tuna with a fork. Stir in mayonnaise, mustard, celery, onion, relish (if using), lemon juice, garlic powder, pepper, and a pinch of salt. Taste; tuna brands vary in saltiness.
- Assemble. Butter one side of each bread slice. Place two slices butter-side down on a cutting board. Layer cheese, a generous scoop of tuna salad, optional tomato, more cheese, then top with the remaining bread (butter-side up).
- Griddle. Heat a large skillet over medium. Cook sandwiches 3-4 minutes per side, pressing gently with a spatula, until the bread is deep golden and the cheese is fully melted. Lower the heat if the bread browns before the cheese melts.
- Rest and slice. Let sit 1 minute, then cut on the diagonal. Serve with pickles.
Tip: Cheese on both sides of the tuna acts like glue. The sandwich stays together when you flip.
How to Build a Perfect Tuna Melt Sandwich
Drain the tuna hard. Excess water is the enemy of a crisp melt. Press the lid into the can over the sink, or tip tuna into a sieve and press with a spoon for 10 seconds.
Use medium heat, not high. You’re toasting bread and melting cheese. Rushing gives you burnt toast and cold cheddar in the middle. Prefer an open-faced version? Pile tuna and cheese on one slice, broil 2-3 minutes until bubbly.

Best Bread for a Tuna Melt Sandwich
A sturdy loaf makes all the difference. Sourdough stays crisp and holds the filling well, while thick white bread delivers a classic diner-style sandwich. Whole wheat adds extra flavor and fiber.
Avoid very thin sandwich bread, which can become soggy before the cheese melts.
Make your own loaf? Our sandwich bread recipe gives you thick, toastable slices that were basically invented for melts.
Best Cheese for a Tuna Melt
Classic cheddar gives the best balance of flavor and meltability. Swiss creates a milder sandwich, while Monterey Jack melts extra smoothly. American cheese also works if you want a creamy diner-style finish.
Chef Emily’s Tips for the Best Tuna Melt
- Sturdy bread matters. Soft sandwich bread can tear; sourdough or bakery loaf holds up.
- Don’t overstuff. Too much tuna slides out when you flip.
- Shredded cheese melts faster than thick cold slices straight from the fridge.
- Butter the outside only. That golden crust comes from fat on the outer bread, not a soggy interior.

Griddling the tuna melt
Easy Variations
- Open-faced: One slice bread, tuna, cheese; broil until melted
- Spicy: Add a pinch of cayenne or a few dashes of hot sauce to the salad
- Dill pickle: Swap relish for chopped dill pickles + a pinch of dill
- Turkey Bacon Tuna Melt: Add 2 slices of crispy turkey bacon before grilling for extra smoky flavor and crunch
- Jalapeño Tuna Melt: Stir chopped pickled jalapeños into the tuna salad, or layer thin fresh jalapeño slices under the cheese
- Mozzarella Tuna Melt: Swap cheddar for mozzarella for a milder, stretchier melt
- Mediterranean Tuna Melt: Add chopped olives, a spoon of chopped roasted red peppers, and a pinch of dried oregano
- Avocado: Add thin avocado slices under the cheese (eat right away)
What to Serve With It
- Dill pickles or a simple cucumber salad
- Tomato soup or another cozy bowl like easy healthy lentil soup
- A crisp green salad from our lean and green dinner ideas
- Crispy sweet potato fries or chips
- Homemade sandwich bread toasted on the side
- Iced tea or lemonade
Storage
Tuna salad: Fridge in an airtight container up to 3 days. Assemble and griddle when you’re ready so the bread stays crisp.
Cooked sandwiches: Best fresh. Reheat in a skillet over medium-low so the bread crisps again.
Freezing: Tuna salad freezes poorly because mayonnaise separates after thawing, so it’s best enjoyed fresh or refrigerated for up to 3 days. Assembled or cooked melts also lose their crisp texture after freezing, so skip the freezer for this one.
Tuna note: Canned tuna is convenient pantry protein. For everyday eating guidance on fish choices, see the FDA advice about eating fish (light tuna is generally a more frequent option than albacore).
FAQ
What is a tuna melt sandwich recipe made of?
Drained tuna mixed with mayo and mix-ins, layered with cheese on bread, then grilled until the bread is crisp and the cheese melts.
Can I use tuna in oil?
Yes. Drain well and use a little less mayonnaise so the salad doesn’t get greasy.
Best cheese for a tuna melt?
Cheddar is classic and melts beautifully. American, Swiss, Monterey Jack, or a cheddar-Jack mix also work.
How do I keep my tuna melt from getting soggy?
Drain tuna thoroughly, butter the outer bread (not the inside), and cook in a skillet, not the microwave.
Can I make tuna melts in the oven?
Yes. Assemble open-faced on a sheet pan and bake at 400°F (200°C) for about 8-10 minutes until cheese melts and edges crisp.
Can I make a tuna melt in an air fryer?
Yes. Assemble the sandwich, lightly butter the outside, and air fry at 370°F (185°C) for about 5-7 minutes, flipping halfway, until the bread is golden and the cheese is melted. Watch closely so the bread doesn’t over-brown.
Can I use canned salmon?
Yes. Drain canned salmon well and use it in place of tuna for a similar melt with a milder, richer flavor.
Can I make it without mayonnaise?
Yes. Use mashed avocado, Greek yogurt, or a mix of yogurt and a little olive oil for creaminess. Texture will be a bit different, but it still melts well.
Can I use Greek yogurt?
Yes. Swap all or part of the mayonnaise for plain Greek yogurt. Start with the same amount, then add a spoonful more if the salad seems dry.
Closed sandwich or open-faced?
Both count as a tuna melt. Closed is more portable; open-faced is faster under the broiler.
