There’s something beautifully simple about a Garlic Herb Tomato Sandwich. Thick heirloom tomato slices, toasted sourdough, and creamy garlic herb mayo bring it to life. This sandwich is more than just nostalgic—it’s the fresh, satisfying bite of summer you’ve been craving.
Every layer is loaded with flavor. Juicy tomatoes are drizzled with olive oil and sprinkled with sea salt. They’re nestled between golden toasted bread and a dreamy mayo packed with garlic, basil, and chives. Best of all? It comes together in under 10 minutes with just a few ingredients.
Tomato sandwiches have humble roots. During the Depression era, families made the most of what they had. Today, we honor that tradition—only now, we elevate it with bold herbs and the best seasonal produce. Perfect for lunch or a light summer dinner, this sandwich delivers comfort, crunch, and fresh flavor in every bite.
Recipe Yield: 2 servings
INGREDIENTS
4 slices sourdough bread, toasted
2 tbsp mayonnaise
1 garlic clove, finely grated
1 tbsp finely chopped fresh basil
1 tsp chopped fresh chives
½ tsp Dijon mustard
2 large heirloom tomatoes, thickly sliced
½ tsp sea salt
¼ tsp black pepper
1 tbsp olive oil
Optional: 2 leaves romaine or butter lettuce
INSTRUCTIONS
1. Make the Garlic Herb Mayo:
In a small bowl, mix together mayonnaise, grated garlic, chopped basil, chives, and Dijon mustard until smooth. This will be your flavor-packed sandwich spread.
2. Prep the Tomatoes:
Slice tomatoes about ½-inch thick. Drizzle with olive oil, season with salt and pepper, and let sit for 5 minutes to enhance their natural flavor and juiciness.
3. Toast the Bread:
Toast the sourdough slices until golden and crisp. The crunch is essential—it keeps the sandwich from turning soggy.
4. Assemble the Sandwich:
Spread garlic herb mayo on all 4 slices of toasted bread. Add thick tomato slices to two of them, and layer in the lettuce if using. Top with the remaining slices, mayo side down.
5. Serve Immediately:
Slice the sandwiches in half and enjoy right away while the bread is warm and the tomatoes are juicy.
Helpful Tips to Perfect This Recipe
- Use Peak-Season Tomatoes: Heirloom or vine-ripened tomatoes deliver the best flavor. Their rich texture and vibrant color bring this sandwich to life.
- Don’t Skip Toasting: Toasting the bread helps it hold up to the juicy tomato slices and creamy mayo without getting soggy.
- Let Tomatoes Rest: A few minutes of resting after salting allows them to release juices and become more flavorful—don’t rush this step!
