I grew up watching my grandmother make these with tomatoes warm from the vine and a jar of Duke’s mayo always close by. She kept it simple – bread, tomatoes, salt, and mayo – and somehow, that was always enough. Over the years, I’ve added little twists here and there, like fresh basil or chives, but the heart of the sandwich remains the same.

Helpful Tips to Make a Tomato Sandwich

Use soft white sandwich bread – This isn’t the time for sourdough or hearty multigrain. Soft, squishy bread soaks up the tomato juice just right.
Go with high-quality mayo – Duke’s is the gold standard in the South, but Hellmann’s or homemade mayo will also work.
Tomatoes should be at peak ripeness – Slightly overripe is actually perfect. Look for tomatoes that are heavy, deeply colored, and fragrant.
Eat it right away – The longer it sits, the soggier it gets. This sandwich is meant to be enjoyed the moment it’s assembled.
Want extra crunch? – Add a leaf of butter lettuce or a couple of thin cucumber slices. Still traditional, just with a little texture twist.

Ingredients

2 slices soft white bread (soft homemade bread work best)
1 large ripe heirloom or beefsteak tomato, sliced thick
2 tablespoons mayonnaise (Duke’s is the Southern favorite)
¼ teaspoon salt
¼ teaspoon black pepper
1–2 fresh basil leaves or a sprinkle of chopped chives (optional)

How to Make a Tomato Sandwich

Spread a generous layer of mayonnaise on both slices of bread.

2. Slice the tomato into thick rounds, at least ¼-inch thick.
Tip: Thicker slices hold up better and prevent the sandwich from becoming too watery. Heirloom or beefsteak tomatoes work best for flavor and juiciness.

3. Lightly salt the tomato slices and let them sit for 1–2 minutes.
Tip: This pulls out excess moisture and brings out the natural sweetness of the tomato—don’t skip this step.

4. Layer the tomato slices on one piece of the mayo-covered bread. Sprinkle with black pepper and a little more salt if desired.
Optional: Add basil leaves or chopped chives for a little herbal freshness—it’s a great way to elevate the classic without changing it too much.

5. Top with the second slice of bread and press gently. Serve immediately!

Frequently Asked Questions

1. Can I use store-bought tomatoes for this?

Yes, but it’s best when made with peak-season tomatoes from a local farm stand or garden. Off-season tomatoes can be watery and less flavorful. I recommend beefsteak or heirloom.

2. What’s the best mayonnaise to use?

Duke’s mayonnaise is the go-to in most Southern kitchens for its tangy flavor and creamy texture. If you can’t find it, Hellmann’s or another full-fat brand will work.

3. Can I toast the bread?

You can, but part of the charm is the soft bread soaking up the tomato juices. If you do toast it, just lightly so you still get that classic texture.

4. How can I prevent the sandwich from getting soggy?

Spread mayo edge to edge, salt the tomatoes and let them rest briefly, and eat the sandwich right after assembling.

5. Is this sandwich good for a crowd or party?

It’s best made fresh and eaten right away, but you can prep the ingredients ahead and assemble just before serving. For parties, try cutting into quarters and serving as tea sandwiches.

This classic Southern tomato sandwich is a summer ritual. With juicy tomatoes, creamy mayo, and soft bread, every bite tastes like home, no matter where you are. Keep it simple, serve it fresh, and enjoy the taste of Southern comfort food done right!
