Ingredients
- 1 x 4oz (115g) can tuna chunks, drained
- 2 stalks celery, diced
- 4 tablespoons mayonnaise, divided
- 2 tablespoons extra virgin olive oil
- 1 tablespoon lemon juice
- ½ teaspoon salt
- ¼ teaspoon ground black pepper
- 8 slices bread (your choice: white, whole wheat, sourdough)
- 4 slices cheddar cheese
- 2 tomatoes, sliced
How To Make Tuna Melt
Step 1: Prepare the Tuna Salad
In a medium bowl, combine the drained tuna chunks and diced celery. Add 3 tablespoons of mayonnaise, the extra virgin olive oil, lemon juice, salt, and pepper. Mix everything gently until well combined. Taste and adjust seasoning if needed. The tuna salad should be creamy with a slight zing from the lemon.
Step 2: Assemble the Sandwiches
Lay out your slices of bread on a clean surface. Spread the remaining 1 tablespoon of mayonnaise on one side of each slice — this helps to create a golden, crispy exterior when grilled. On four slices of bread, evenly distribute the tuna salad on top of the mayo spread.
Step 3: Add Cheese and Tomato
Place a slice of cheddar cheese over the tuna salad on each sandwich. Then add slices of tomato on top of the cheese. Cover each sandwich with the remaining bread slices, mayo side down.
Step 4: Cook the Tuna Melts
Heat a large skillet or griddle over medium heat. Place the sandwiches in the skillet and cook for about 3-4 minutes per side, pressing down gently with a spatula, until the bread is toasted golden brown and the cheese has melted. You can cover the skillet with a lid to help the cheese melt evenly.
Step 5: Serve and Enjoy
Remove the tuna melts from the skillet and let them cool for a minute. Slice each sandwich in half and serve warm. These sandwiches pair wonderfully with a side salad, chips, or a cup of soup.
Expert Tips
- For extra flavor, add a pinch of smoked paprika or garlic powder to the tuna salad.
- If you prefer, swap the cheddar cheese for Swiss, provolone, or mozzarella for a different melt texture and taste.
- Use day-old bread or slightly thicker slices for sturdier sandwiches that hold up well to grilling.
- To avoid soggy bread, make sure to drain the tuna thoroughly before mixing and don’t overload the sandwiches with too much tomato.
- For a lighter option, swap mayonnaise with Greek yogurt or avocado spread.
- Use a panini press if you have one for perfectly even grilling and crispy crust.
Variations and Customizations
- Spicy Tuna Melt: Add a few dashes of hot sauce or chopped jalapeños to the tuna salad for a spicy kick.
- Herb-Infused: Mix in fresh chopped herbs like dill, parsley, or chives to brighten the flavor.
- Crunch Factor: Add chopped pickles or capers for a tangy crunch.
- Gluten-Free: Use gluten-free bread to accommodate dietary restrictions without sacrificing taste.
- Open-Faced Version: Toast the bread, then top with tuna salad, cheese, and tomato slices, broil until the cheese melts for an open-faced delight.
- Vegan-Friendly: Substitute the tuna with mashed chickpeas, use vegan mayo, and dairy-free cheese.
How to Store Leftovers
If you have any leftover tuna salad, store it in an airtight container in the refrigerator. It will keep well for up to 3 days. For the sandwiches, it’s best to assemble and toast them fresh, as the bread can become soggy if stored assembled. However, if you want to prepare ahead, you can make the tuna salad and slice the tomatoes in advance, then assemble and grill the sandwiches right before serving. If you do have leftover grilled sandwiches, wrap them tightly in foil and store in the fridge for up to 1 day. Reheat in a skillet or oven to keep the bread crispy and cheese melty.
FAQ
Can I use different types of cheese for the tuna melt?
Absolutely! While cheddar is classic because of its sharp flavor and great melting quality, you can use Swiss, provolone, mozzarella, or even pepper jack if you want a little spice. Each cheese will bring a unique twist to your tuna melt.
Is canned tuna the best option for this recipe?
Yes, canned tuna chunks work perfectly because they have a firm texture and are easy to mix with other ingredients. Just make sure to drain it well. If you prefer, you can use fresh cooked tuna, but it will be a bit more time-consuming and expensive.
Can I make this recipe dairy-free?
Definitely! To make this tuna melt dairy-free, simply swap out the cheddar cheese for a plant-based cheese alternative and use a dairy-free mayo. The sandwich will still be delicious and creamy.
How can I make the tuna salad healthier?
You can reduce the mayo or replace some or all of it with Greek yogurt or mashed avocado for a healthier fat profile. Also, adding more celery or fresh herbs can increase the nutritional value without sacrificing flavor.
