Ingredients for Sheet Pan Tuna Melts
Below is a clean, easy-to-follow list of everything you need to make these incredibly satisfying tuna melts:
- 2 cans tuna, drained
- 1/3 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 rib celery, minced
- 2 tablespoons finely chopped red onion
- 1 tablespoon lemon juice
- 1/4 teaspoon garlic powder
- Salt and pepper to taste
- 1 cup shredded cheddar or a cheddar-mozzarella blend
- 6–8 slices thick-cut bread
- 2 tablespoons softened butter (optional, for spreading)
- Fresh parsley for garnish
Instructions
1. Preheat and Prep
Preheat your oven to 400°F (205°C). Line a sheet pan with parchment paper for easy cleanup. If you like crisp edges, lightly butter one side of each slice of bread.
2. Make the Tuna Salad
In a medium bowl, combine tuna, mayonnaise, mustard, celery, onion, lemon juice, garlic powder, salt, and pepper. Mix until creamy but still slightly chunky.
3. Assemble the Melts
Lay the bread slices on the sheet pan. Divide the tuna mixture evenly over each slice, spreading it all the way to the edges for best browning. Top generously with shredded cheese.
4. Bake
Place the sheet pan into the oven and bake for 10–12 minutes, or until the cheese is melted and bubbly and the edges of the bread are crisp.
5. Optional Broil Finish
For extra golden tops, broil for 1–2 minutes — but keep an eye on them!
6. Serve and Enjoy
Garnish with fresh parsley and serve hot.
Tips for the Best Sheet Pan Tuna Melts
Use Quality Bread
Rustic sourdough, brioche, or bakery sandwich loaves hold up best under the heat and weight of the tuna mixture.
Drain the Tuna Well
Excess liquid can make the melts soggy. Pressing the tuna firmly removes moisture and results in a creamier spread.
Spread the Mixture Completely to the Edges
This ensures the bread browns evenly and prevents dry edges.
Add the Cheese Last
Cheese acts like a blanket to keep the tuna moist while developing a perfectly melted top layer.
Fun Variations
Spicy Tuna Melt
Add 1 teaspoon sriracha or a pinch of red pepper flakes to the tuna mixture.
Mediterranean Tuna Melt
Stir in chopped olives, roasted red peppers, and a sprinkle of feta.
Buffalo Tuna Melt
Replace lemon juice with buffalo sauce and use Monterey jack cheese.
Herbed Lemon Tuna Melt
Add dill or parsley directly to the tuna mixture.
Extra Cheesy Melt
Use a blend of provolone, cheddar, and mozzarella.
Serving Suggestions
- Serve with tomato soup for a classic diner combo.
- Pair with a quick green salad for a lighter meal.
- Add potato wedges or chips for a kid-friendly plate.
- Slice into small rectangles for party-friendly finger food.
Why the Sheet Pan Method Always Wins
By cooking the tuna melts on a sheet pan instead of in a skillet, you unlock advantages like:
- Even heat distribution
- Consistent browning
- No flipping
- Ability to cook in large batches
- Less mess and easier cleanup
This technique also frees up stovetop space and eliminates the greasy, smoky environment that often comes with pan-frying sandwiches.
Frequently Asked Questions
Can I make these ahead of time?
Yes! Prepare the tuna mixture up to 2 days ahead and store in the fridge. When ready, assemble and bake.
Can I freeze tuna melts?
It’s best to freeze only the tuna mixture, not the assembled sandwiches, as bread texture can change.
Can I use different cheeses?
Absolutely — Swiss, provolone, pepper jack, Havarti, or white cheddar are all wonderful.
What’s the best tuna for tuna melts?
Solid albacore tuna (either in water or oil) offers the best texture and flavor, but chunk light tuna works too.
