There is nothing quite like the taste of a fresh tomato sandwich on a warm afternoon. It is one of those meals that relies entirely on using the best ingredients you can find, specifically a perfectly ripe tomato that is bursting with flavor.

My secret to taking this sandwich to the next level is the homemade basil mayo. It adds a lovely herbal brightness that makes the simple white bread and juicy tomato feel like a special treat. I suggest using a sturdy soft white bread so it holds up to all those delicious juices.

🧺 Ingredients

2 thick slices of soft white bread
1 large ripe tomato, sliced into thick rounds
2 tablespoons mayonnaise
4 fresh basil leaves, finely chopped
1 pinch of flaky sea salt
1 pinch of freshly cracked black pepper
1 teaspoon butter, softened

👩‍🍳Instructions

1
In a small bowl, mix the mayonnaise with the chopped fresh basil until well combined.
2
Lightly butter one side of each slice of bread if you prefer your sandwich toasted, otherwise leave them soft.
3
Spread a generous amount of the basil mayo on the inside of both slices of bread.
4
Layer the thick tomato slices onto the bottom piece of bread.
5
Sprinkle the tomato slices with sea salt and black pepper to draw out the sweetness.
6
Place the second slice of bread on top and press down very gently before slicing the sandwich in half.

💡 Tips

Eat this sandwich immediately after assembling so the bread does not get too soggy. If you want a little extra crunch, you can lightly toast the bread before adding your mayo. Store any leftover basil mayo in a small jar in the fridge for up to three days.
