Ingredients You’ll Need for This Bold and Comforting Sandwich
This recipe uses everyday ingredients but transforms them into something you’ll want to make again and again.
For the Spicy Tuna Filling:
- 1 can tuna (drained)
- 2–3 tbsp mayonnaise
- 1–2 tsp sriracha or chili paste
- 1 tsp soy sauce (optional)
- 1 tsp lemon juice
- 1 small red onion, finely diced
- 1 tbsp finely chopped green onions or chives
- 1 small celery stalk, finely diced (optional)
- Salt and black pepper to taste
For the Garlic Butter Brioche:
- 2 thick slices brioche bread
- 1–2 tbsp softened butter
- 1 small garlic clove, grated
- Pinch of parsley (fresh or dried)
Building the Spicy Tuna Filling – Creamy with a Kick
Start by combining the tuna, mayonnaise, sriracha or chili paste, lemon juice, and soy sauce in a bowl. Mix until the tuna is fully coated and creamy. You should see a slightly rosy color from the chili—this is where the flavor begins.
Next, fold in the red onion, green onions, and celery if you’re using it. These add crunch and freshness, balancing the richness of the mayonnaise. Season with salt and black pepper to taste. The filling should be creamy, a bit spicy, and brightened with the acidity of lemon juice. Let it rest for a few minutes so the flavors meld together.
Making the Garlic Butter – Simple but Essential
In a small bowl, mix the softened butter with the grated garlic and parsley. This quick homemade garlic butter is what makes the sandwich irresistible. As it toasts, the garlic becomes golden and fragrant, creating that perfect crispy, buttery crust on the brioche.
Assembling the Sandwich
Spread the garlic butter generously on the outside of both brioche slices—yes, the outside. This ensures every bite has that rich, toasty flavor. Then pile a generous amount of the spicy tuna filling between the slices. Don’t be shy with the filling; the brioche can hold it.
Toasting the Sandwich to Golden Perfection
Heat a nonstick pan over medium heat. Once warm, place the sandwich in the pan and toast it for about 2–3 minutes per side. You’ll hear a gentle sizzle as the garlic butter crisps up and the brioche turns golden. Press lightly with a spatula for even browning.
The outside should be crisp and buttery, while the inside becomes warm and creamy. Sometimes a little tuna filling escapes from the side while toasting—that’s normal and honestly part of the charm.
Serving and Enjoying
Serve the sandwich hot, straight from the pan. The contrast between the crunchy brioche and the creamy spicy tuna is the kind of texture combination that makes you stop mid-bite and appreciate what’s happening. Pair it with a simple salad, chips, or just enjoy it alone—it’s satisfying enough to stand on its own.
