Step-by-Step Instructions

1. Preheat Your Grill or Skillet: Fire up your gas grill to medium-low heat (around 350°F). If you’re using a charcoal grill, push the coals to one side for indirect heat. Alternatively, you can use a cast-iron skillet on your RV stovetop.
2. Make the Tuna Salad: In a medium bowl, combine the drained tuna, mayonnaise, mustard, and celery (or pickles). Mix well until everything is evenly combined. Season with salt and pepper to taste.
3. Assemble the Sandwiches: Butter one side of each slice of bread. Lay two slices, butter-side down, on a clean surface. Top each with a slice of cheese, then a generous amount of tuna salad, then another slice of cheese. Place the remaining bread slices on top, butter-side up.
4. Grill the Melts: Carefully place the assembled sandwiches on the preheated grill or skillet. Cook for 3-4 minutes per side, or until the bread is golden brown and crispy, and the cheese has melted into a delicious, gooey mess. If using a grill, close the lid to trap heat and help melt the cheese faster.
5. Serve and Enjoy: Remove from the grill and let cool for a minute before slicing in half. The combination of the creamy tuna, melted cheese, and crispy, buttery bread with a hint of smoky flavor is pure comfort food perfection!

Tips for the Perfect Grilled Tuna Melt

Getting that diner-style tuna melt is all about technique. Here are some simple tips to ensure your sandwiches turn out perfectly every single time.

• Avoid Soggy Bread: The biggest enemy of a good tuna melt is a soggy bottom. To prevent this, drain your tuna very well. Also, buttering the outside of the bread creates a barrier that seals out moisture, giving you that perfect crispy crust.
• Get Perfect Grill Marks: To achieve beautiful grill marks on your bread, place the sandwich on the grill at a 45-degree angle for 1-2 minutes before rotating it 90 degrees. This technique works great on both charcoal grill and gas grill grates.
• Control Your Heat: Grilling sandwiches is all about medium-low heat. Too high and the bread will burn before the cheese melts. If you’re using a gas grill, you have precise temperature control. For a charcoal grill, keep the coals on one side and use indirect heat to melt the cheese slowly and evenly.
• Keep It Closed: Resist the urge to peek! Pressing down on the sandwich with a spatula can squeeze out the filling and make it dry. Instead, close the grill lid and let the trapped heat do its magic, melting the cheese to perfection.

Delicious Variations

This pantry-friendly recipe is super versatile. Here are some fun ways to customize your tuna melt based on your mood or what you have on hand.

• Spicy Kick Version: Add a dash of hot sauce, red pepper flakes, or a few slices of jalapeños to the tuna salad. Top with pepper jack cheese for an extra layer of heat.
• BBQ Tuna Melt: Swap the mustard for your favorite BBQ sauce. Drizzle a little extra sauce over the tuna before adding the cheese. The sweet and tangy flavors pair beautifully with the smoky flavor from the grill.
• Mediterranean Version: Replace the celery with chopped kalamata olives and sun-dried tomatoes. Use feta cheese instead of cheddar for a tangy, briny twist.
• Everything Bagel Version: Sprinkle everything bagel seasoning on the buttered outer sides of the bread before grilling. This adds a ton of flavor and a wonderful textural crunch.
• Open-Faced Deluxe Version: Skip the top slice of bread. Toast one side of the bread on the grill, flip it over, and pile on the tuna and cheese. Grill until the cheese is bubbly and golden for a lower-carb option.

Storage Instructions

If you happen to have leftovers, here’s how to keep them tasty for later.

• How to Store: It’s best to store the tuna salad separately from the bread. Keep the tuna salad in an airtight container in the refrigerator for up to 2 days. The grilled sandwiches are best enjoyed fresh, but you can store assembled, uncooked sandwiches wrapped in foil in the fridge for a day.
• How to Reheat: To bring back that crispy texture, reheat leftover tuna melts in a dry skillet over medium-low heat or on the gas grill for a few minutes per side. Avoid the microwave, as it will make the bread rubbery and the tuna soggy.

Frequently Asked Questions (FAQ)

Can I use a cast iron skillet instead of a grill?

Absolutely! A cast iron skillet is perfect for making tuna melts. It gives you that same beautiful golden crust and melts the cheese evenly. It’s a great option if you’re cooking inside your RV or don’t want to fire up the charcoal grill.

What’s the best bread for a tuna melt?

Sourdough and hearty white bread are classic choices because they’re sturdy enough to hold the filling and toast up beautifully. Rye bread, English muffins, or even thick-cut brioche work wonderfully too.

How do I stop my tuna melt from falling apart?

Be careful not to overstuff your sandwich. A generous but manageable amount of tuna salad, around ½ cup per sandwich, is perfect. Also, make sure your bread is thick enough to support the filling without tearing.

Can I make this without mayonnaise?

Yes! You can use Greek yogurt, mashed avocado, or even a drizzle of olive oil and lemon juice to bind your tuna salad. Each option will give it a different flavor profile, but they all work wonderfully.

How do I get that smoky flavor without a grill?

While a grill gives the best smoky flavor, you can add a drop of liquid smoke to the tuna salad mixture. Alternatively, using smoked cheddar or Gouda cheese will infuse your sandwich with that delicious BBQ taste.
