Tuna melts are a delightful and quick-to-make comfort food that combines the savory flavors of tuna with the creamy richness of cheddar cheese. Perfect for a quick lunch or a light dinner, these open-faced sandwiches are sure to satisfy your cravings. The combination of mayonnaise and dijon mustard adds a tangy twist, making each bite a burst of flavor.
If you don't usually keep dijon mustard in your pantry, you might need to pick some up at the supermarket. It's a bit more refined than regular mustard and adds a nice depth of flavor to the tuna mixture. Everything else in this recipe is pretty standard and should be easy to find.

How to Store or Freeze This Dish
Allow the tuna melts to cool completely before storing. This helps prevent condensation, which can make the bread soggy.
For short-term storage, place the tuna melts in an airtight container. You can layer them with parchment paper to avoid sticking. Store in the refrigerator for up to 3 days.
If you plan to freeze the tuna melts, wrap each piece individually in plastic wrap or aluminum foil. This ensures they remain intact and prevents freezer burn.
Place the wrapped tuna melts in a freezer-safe bag or container. Label with the date to keep track of freshness. They can be frozen for up to 2 months.
When ready to enjoy, thaw the tuna melts in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
To reheat, preheat your oven to 350°F (175°C). Place the tuna melts on a baking sheet and cover loosely with foil to prevent the bread from drying out. Heat for about 10-15 minutes, or until warmed through and the cheese is melted.
Alternatively, you can reheat in a toaster oven or microwave. For the microwave, use a microwave-safe plate and heat on medium power in 30-second intervals until warm. Be cautious as the bread may become slightly chewy.
How to Reheat Leftovers
Oven Method:
- Preheat your oven to 350°F (175°C).
- Place the leftover tuna melts on a baking sheet.
- Cover them loosely with aluminum foil to prevent the bread from drying out.
- Bake for about 10-15 minutes, or until the cheese is melted and the tuna mixture is heated through.
- Remove the foil for the last 2-3 minutes to crisp up the bread if desired.
Toaster Oven Method:
- Preheat your toaster oven to 350°F (175°C).
- Place the tuna melts directly on the toaster oven rack or on a small baking sheet.
- Heat for about 8-10 minutes, or until the cheese is melted and bubbly.
- For a crispier bread, you can toast for an additional 1-2 minutes.
Microwave Method:
- Place the tuna melts on a microwave-safe plate.
- Cover with a microwave-safe lid or a damp paper towel to retain moisture.
- Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
- If the cheese isn't fully melted, continue microwaving in 15-second intervals.
Skillet Method:
- Preheat a non-stick skillet over medium heat.
- Place the tuna melts in the skillet, cheese side up.
- Cover the skillet with a lid to help the cheese melt evenly.
- Heat for about 5-7 minutes, or until the tuna mixture is warmed through and the cheese is melted.
- For a crispier bread, you can flip the tuna melts carefully and toast the bottom for an additional 1-2 minutes.
