Open-Faced Cheddar Tuna Melts with Quick Cucumber Salad

Ingredients

For the Quick Cucumber Salad:

• 1 English cucumber, thinly sliced into rounds
• 1 tbsp apple cider vinegar
• 1 tbsp extra-virgin olive oil
• 1 tsp sugar
• 1 tbsp chopped fresh dill
• 1/4 tsp kosher salt

For the Classic Tuna Salad:

• 2 cans (5 oz each) solid white albacore tuna in water, drained
• 1/4 cup mayonnaise
• 2 tbsp plain Greek yogurt
• 1 tbsp Dijon mustard
• 2 ribs celery, finely diced
• 2 tbsp finely chopped red onion
• 1 tbsp fresh lemon juice
• 1/4 tsp kosher salt
• 1/4 tsp freshly cracked black pepper

For the Melts & Assembly:

• 4 thick slices artisan sourdough bread
• 2 tbsp unsalted butter, softened
• 4 oz (1 cup) sharp yellow cheddar cheese, coarsely shredded

Equipment

• Matte-black baking sheet
• Parchment paper
• Medium glass mixing bowl
• Small mixing bowl
• Fork and spatula
• Chef's knife
• Warm oak cutting board
• Measuring spoons and cups

Instructions

1. Position your oven rack 6 inches below the top heating element and turn on the broiler to HIGH.

1. Line your matte-black rimmed heavy baking sheet with a piece of parchment paper.

1. Prepare the quick cucumber salad by tossing the thinly sliced English cucumber rounds in a small bowl with apple cider vinegar, extra-virgin olive oil, sugar, fresh dill, and 1/4 teaspoon salt until coated, then set aside in the refrigerator.

1. Flake the drained solid white albacore tuna into a medium mixing bowl using a fork until broken into fine bite-sized flakes.

1. Add the mayonnaise, Greek yogurt, Dijon mustard, diced celery, chopped red onion, lemon juice, salt, and black pepper to the tuna bowl, folding gently until creamy and combined.

1. Spread softened butter thinly over both sides of each artisan sourdough bread slice, then place the bread slices onto the prepared matte-black rimmed heavy baking sheet.

1. Broil the buttered sourdough slices under the hot broiler for 2 to 3 minutes until the bread surface turns light golden brown and crisp around the edges.

1. Remove the baking sheet carefully from the oven using oven mitts and turn the toasted bread slices over so the pale toasted side faces up.

1. Scoop equal amounts of the tuna salad mixture onto each toasted sourdough slice, spreading the tuna evenly out to the edges of the bread.

1. Top each tuna layer generously with shredded sharp cheddar cheese, making sure the cheese covers the tuna completely to prevent drying under the broiler.

1. Return the matte-black rimmed heavy baking sheet to the broiler and cook for 3 to 4 minutes until the cheddar cheese melts completely, turns bubbly, and develops golden brown spots on top.

1. Transfer the open-faced tuna melts onto cream stoneware plates using a spatula and serve immediately alongside the chilled quick cucumber salad.

Chef's Tips

• Pre-Toast the Bread First: Broiling buttered sourdough slices before adding tuna salad creates a moisture barrier that keeps bread wonderfully crispy instead of soggy.
• Cheese Selection: Sharp yellow cheddar offers great color and flavor, but Gruyère, Swiss, or pepper jack work wonderfully.
• Tuna Drain Technique: Press the canned tuna lid firmly over the sink to remove excess liquid so the salad stays rich and thick.
