A tuna melt is a classic comfort food that combines the savory flavors of tuna with the creamy richness of cheddar cheese. Perfect for a quick lunch or a simple dinner, this sandwich is both satisfying and easy to make. The crispy, buttery bread adds a delightful crunch to every bite.
Most of the ingredients for this tuna melt recipe are common pantry staples. However, if you don't have dijon mustard at home, you might need to pick it up at the supermarket. This ingredient adds a tangy depth of flavor to the tuna mixture that regular mustard can't quite match.
Ingredients For Tuna Melt Recipe
Tuna: A can of drained tuna serves as the protein base for the sandwich.
Bread: Choose your favorite type of bread for the sandwich; whole wheat, sourdough, or white bread all work well.
Mayonnaise: Adds creaminess and helps bind the tuna mixture together.
Dijon mustard: Provides a tangy flavor that complements the tuna.
Cheddar cheese: Shredded cheddar cheese melts beautifully and adds a rich, cheesy flavor.
Butter: Used for grilling the sandwich to a golden brown perfection.
Technique Tip for Making a Tuna Melt
To achieve a perfectly golden and crispy tuna melt, ensure your skillet is preheated to the right temperature before adding the sandwich. This helps in evenly browning the bread and melting the cheese uniformly. Additionally, pressing down gently with a spatula while grilling can enhance the contact between the bread and the butter, resulting in a more even crust.

How to Store or Freeze Your Tuna Melt
- Allow the tuna melt to cool completely before storing. This helps prevent condensation, which can make the bread soggy.
- Wrap each sandwich individually in plastic wrap or aluminum foil. This ensures they stay fresh and prevents any unwanted flavors from seeping in.
- Place the wrapped tuna melts in an airtight container or a resealable plastic bag. This provides an extra layer of protection against freezer burn.
- Label the container or bag with the date. This helps you keep track of how long the sandwiches have been stored.
- Store the tuna melts in the refrigerator if you plan to eat them within 2-3 days. For longer storage, place them in the freezer, where they can last up to 1 month.
- When ready to enjoy, thaw frozen tuna melts in the refrigerator overnight. This ensures even thawing and maintains the texture of the bread.
- Reheat the sandwiches in a skillet over medium heat, using a bit of butter to crisp up the bread. Alternatively, you can use a toaster oven or conventional oven at 350°F (175°C) for about 10 minutes, or until heated through and the cheese is melted.
- Avoid microwaving, as this can make the bread chewy and the tuna melt less enjoyable.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the tuna melt in aluminum foil to retain moisture. Bake for about 10-15 minutes or until the cheese is melted and the sandwich is heated through.
Use a skillet over medium heat. Place the tuna melt in the skillet and cover it with a lid. Heat for about 3-4 minutes on each side, or until the cheese is melted and the bread is crispy.
For a quick option, use a microwave. Place the tuna melt on a microwave-safe plate and cover it with a damp paper towel to prevent it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place the tuna melt in the air fryer basket and heat for about 3-5 minutes, or until the cheese is melted and the bread is crispy.
