Ingredients

Serves 6 toasts

The egg salad:

  • 4 eggs
  • 1 tbsp whole grain Dijon mustard
  • 1 tbsp fresh lemon juice
  • 2 tbsp olive oil
  • 1 tbsp chopped fresh dill
  • salt
  • pepper

The tuna:

  • 8 oz sushi-grade tuna steak
  • 1 tbsp coarsely cracked black pepper
  • 1 tbsp neutral oil (avocado or canola)

Assembly:

  • 3 slices sourdough bread, halved
  • Extra fresh dill, for garnish
  • Flaky salt, for serving
  • Lemon wedges, for serving

Instructions 

  • Cook the eggs: Bring a small pot of water to a boil. Carefully add the eggs and cook for 7 minutes for jammy centers. Transfer immediately to an ice bath and let cool completely before peeling.
  • Make the vinaigrette: In a medium bowl, whisk together the whole grain Dijon, lemon juice, olive oil, dill, salt, and pepper.
  • Prepare the egg salad: Roughly chop the eggs and fold them into the vinaigrette. The mixture should be chunky with visible pieces of jammy yolk. Set aside.
  • Season the tuna: Pat the tuna dry and season all sides with the salt. Press the cracked black pepper evenly over the exterior. (see note)
  • Sear the tuna: Heat the neutral oil in a skillet over high heat until shimmering. Sear the tuna for about 30–45 seconds per side, including the edges, until a thin crust forms while the center remains rare. Transfer to a cutting board and let rest for 2 minutes before slicing thinly. Make sure to not wait longer than 2 minutes as the tuna will continue to cook.
  • Toast the bread: Toast the sourdough halves until golden and crisp.
  • Assemble: Spoon the egg salad evenly over each toast. Top with slices of seared tuna and garnish with additional dill, flaky salt, and a squeeze of fresh lemon juice.
  • Serve: Enjoy immediately while the toast is crisp and the tuna is freshly seared.

Notes

Note: The serving size for this recipe is 3 full toasts, or 6 toasts cut in half. This recipe works as a toast enjoyed for lunch, or cut in half for an appetizer.
Note: If it is a large piece of tuna, you can cut the tuna into large strips to ensure you get the perfect sear on all pieces. Alternatively, you can keep it in one piece to cook.
