How to Make This sheet pan tuna salad Recipe

1. Preheat the oven: Preheat your oven to 375°F (190°C). Lightly grease a large sheet pan.
2. Prepare the tuna salad: In a medium bowl, combine the drained tuna, mayonnaise, celery, red onion, sweet pickle relish, Dijon mustard, and black pepper. Mix until well combined. Taste and adjust seasonings as needed.
3. Assemble the sheet pan: Spread softened butter on one side of each slice of bread. Place four slices of bread, butter side down, on the prepared sheet pan.

5. Add the cheese: Place a slice of cheddar cheese on top of the tuna salad on each slice.

7. Bake: Bake for 12 to 15 minutes, or until the bread is golden brown and the cheese is melted and bubbly. Keep a close eye on the bread, as baking times may vary depending on your oven.

How to Serve This sheet pan tuna salad Recipe

Serve this sheet pan tuna salad warm, straight from the oven. Cut it into squares or triangles for easy handling. A side of crisp dill pickles or a simple green salad makes the perfect complement.

For a complete meal, consider pairing it with your favorite soup. Tomato or creamy vegetable soup are both excellent choices. You could also add a side of potato chips for a little extra crunch.

How to Store This sheet pan tuna salad Recipe

Store any leftover sheet pan tuna salad in an airtight container in the refrigerator. It will keep for up to 2 days. Keep in mind that the bread will soften as it sits.

Reheating is best done in the oven or a toaster oven to re crisp the bread. Microwaving will make the bread soggy. It’s best enjoyed fresh, but leftovers still make a satisfying snack.

Tips to Make This sheet pan tuna salad Recipe

For extra flavor, try adding a pinch of cayenne pepper or a dash of hot sauce to the tuna salad.
Want a creamier tuna salad? Add a tablespoon of cream cheese or sour cream.
Don’t over bake! Over baking will make the bread hard and the cheese dry. Keep a close eye on it in the oven.

Helpful Notes for This sheet pan tuna salad Recipe

The type of bread you use can greatly affect the final result. Sourdough or artisan bread holds up well to baking and provides a lovely texture. Regular sandwich bread will work too, but it may become softer.

If you’re using tuna packed in oil instead of water, make sure to drain it well to prevent the tuna salad from being too greasy. You can also experiment with different cheeses like provolone, Monterey Jack, or even a sprinkle of Parmesan for added flavor complexity.

Variation of This sheet pan tuna salad Recipe

For a vegetarian version, try swapping the tuna for mashed chickpeas. Add a little lemon juice and zest to brighten up the flavor.

If you’re feeling adventurous, try adding some pesto to the tuna salad for a Mediterranean twist. Sun dried tomatoes and olives would also be great additions.
