Tuna Salad on Croissant: French Savoury Breakfast
Decide whether to serve your tuna salad on croissant cold or toasted before you begin. Use an oven at 180°C (350°F) for 3 minutes if you prefer a warm, golden edge. Toasted pastry prevents the butter from feeling heavy and adds a crisp contrast to the cool filling. Use a pastry brush with a light hand to avoid making the bread soggy.
This French breakfast combines drained tuna with halal mayonnaise, apple cider vinegar, and diced celery. Fold in green onions and pickle relish for a sharp, savoury flavour. The result is a balanced sandwich where the richness of the butter meets the acidity of the vinegar. You may add 80 g of shredded mozzarella for a melted variation.
Tuna Salad on Croissant: French Savoury Breakfast
Recipe cardIngredients
Instructions
-
Prepare the tuna
Open the tuna tins and drain the liquid completely. Transfer the tuna into a medium bowl. Break the tuna into bite-sized flakes with a fork to ensure the dressing coats every piece.
-
Mix the dressing
Add the mayonnaise, mustard, apple cider vinegar, salt and pepper to the tuna. Stir until well combined. The vinegar cuts through the richness of the mayonnaise for a balanced flavour.
-
Fold in vegetables
Gently fold in the sliced green onions, diced celery and pickle relish. Ensure these are evenly distributed so you get a crunch in every bite.
-
Prepare the croissants
Brush the softened butter lightly over the cut-side of each croissant. If you want them warm, place them on a baking tray and heat the oven to 180°C (350°F).
-
Bake the pastry
Bake for 3 minutes until the butter melts and the edges turn golden. If using mozzarella, sprinkle it over the buttered sides before baking to create a melted crust.
-
Cool and assemble
Allow toasted croissants to cool to room temperature to prevent the mayonnaise from separating. Divide the tuna mixture into four equal portions. Spoon the salad onto the bottom half of each croissant and top with the remaining halves.
Drain the tuna completely using a leak-free tin. If you leave too much liquid in the tuna, the salad will become watery and lose its structure. This excess moisture will also make your croissants soggy, destroying the contrast between the crisp pastry and the creamy filling.
What to serve with it
Pair these sandwiches with a side salad of mixed greens dressed in lemon vinaigrette for a fresh contrast. You can also serve crisp cucumber spears with a splash of apple cider vinegar or a hot cup of tomato soup for a more comforting lunch option.
Storing and reheating
Keep leftover tuna salad in a sealed container in the refrigerator for up to 2 days. Assemble the sandwiches as you intend to eat them, as they should be consumed within 24 hours to maintain the correct texture of the croissant.
