How to Make Tuna Sandwich
Ingredients:
- 425g/15 oz canned tuna in oil, drained (Note 1)
- 3/4 cup whole egg mayonnaise or Kewpie (Note 2)
- 3/4 cup finely diced celery (1 stalk, cut in 4 lengthways, then finely diced)
- 5 tbsp finely chopped dill pickle (Note 3)
- 2 tbsp liquid from pickle jar (Note 3)
- 2 tbsp Dijon mustard
- 3 tbsp finely chopped dill (or parsley or basil)
- 1/3 cup finely sliced green onion (~2 stems) (Note 4)
- 1/2 tsp black pepper
- 8 pieces butter lettuce (2 per sandwich)
- Salted butter for spreading
- 8 slices bread or 4 rolls (Note 5)
Directions:
Filling: Put all the Tuna Filling ingredients into a bowl. Mix well using a wooden spoon, breaking up the tuna so the filling becomes fairly smooth. The pickles and celery will get mixed in well, which is good for flavor melding!
Sandwich: Divide the Tuna Filling between 4 sandwiches (or more or less depending on the bread size). I like to butter the bread and use 2 pieces of lettuce per sandwich. Enjoy!
How to Serve Tuna Sandwich
Serve your tuna sandwich fresh with a side of chips or a simple salad. You can cut the sandwich in half for easier eating or serve it whole for a heartier meal. Adding some sliced tomatoes or cucumber inside the sandwich can give an extra refreshing crunch.
How to Store Tuna Sandwich
If you have leftover tuna filling, you can store it in an airtight container in the refrigerator for up to 3 days. However, assembled sandwiches are best eaten fresh. If you must store a sandwich, wrap it tightly in plastic wrap and keep it in the fridge for up to 1 day, but keep in mind that the bread may get soggy.
Tips to Make Tuna Sandwich
- Use high-quality canned tuna for the best flavor.
- Experiment with different herbs or add spices to adjust the taste.
- For a healthier version, use Greek yogurt instead of mayonnaise.
- Toast the bread for an extra crunch.
- Add fresh ingredients like sliced avocado or tomatoes for more flavor and nutrition.
Variation
You can switch things up by using different types of bread, such as whole grain, sourdough, or gluten-free. You might also try adding ingredients like hard-boiled eggs, sweet corn, or even a slice of cheese for added richness.
FAQs
1. Can I make this sandwich ahead of time?
Yes, you can prepare the tuna filling in advance and store it in the fridge. Assemble the sandwich just before serving for the best texture.
2. Can I freeze the tuna filling?
While you can freeze the tuna filling, it’s best to consume it fresh. If you do freeze it, place it in an airtight container, and use it within a month.
3. What type of mayonnaise can I use?
You can use any type of mayonnaise you prefer, or even substitute it with Greek yogurt for a lighter option. Kewpie mayonnaise is a great choice for a richer flavor.
Enjoy making and savoring your tuna sandwich! It’s a timeless recipe that never goes out of style.
