Ingredients
- 2 slices white bread, sourdough, or brioche
- 1 large heirloom tomato, any variety
- 2 tablespoons mayonnaise
- Pinch of salt
- Pinch of black pepper
Step-by-Step Directions
Step 1: Toast the Bread
Preheat a skillet over medium heat. Spread about 1 tablespoon of mayonnaise evenly on both sides of each slice of bread. Toast each slice in the skillet until lightly golden, about 2 minutes per side. This step adds richness and crunch without overwhelming the tomato’s freshness.
Step 2: Prepare the Tomato
Slice your heirloom tomato into thick slabs—about ½ inch is perfect. Lightly sprinkle salt and pepper on both sides of each slice. This enhances the tomato’s natural sweetness and juiciness.
Step 3: Assemble the Sandwich
Spread the remaining mayonnaise generously on the inside of both slices of toasted bread. Layer the seasoned tomato slices onto one piece of bread, then top with the other.
Step 4: Serve and Enjoy
Slice the sandwich in half and enjoy immediately while the bread is still slightly warm and the tomato is bursting with juice.
Tips for Success
- Choose the Right Tomatoes: Heirloom tomatoes are ideal for their unique flavor profiles and juicy texture. Look for ones that are slightly soft to the touch but not mushy.
- Salt at the Last Minute: Adding salt too early can draw out excess moisture from the tomatoes. Salt just before assembling.
- Use Good Bread: A sturdy bread like sourdough or brioche adds flavor and holds up against the juicy tomato. Avoid overly airy bread, which can get soggy.
- Generous Mayonnaise is Key: Don’t skimp—it provides creaminess and richness that balances the acidity of the tomato.
- Eat Immediately: This sandwich is best fresh, before the bread absorbs too much tomato juice.
Variations
- Cheesy Upgrade: Add a slice of sharp cheddar, fresh mozzarella, or goat cheese.
- Herbaceous Twist: Sprinkle fresh basil, parsley, or dill on the tomatoes before closing the sandwich.
- Avocado Addition: Spread mashed avocado alongside the mayonnaise for extra creaminess.
- Bacon Lover’s Version: Add crispy bacon for a simple take on a BLT without the lettuce.
- Spicy Kick: Mix a little hot sauce or sriracha into the mayonnaise for heat.
Serving Suggestions
- Pair with a simple green salad for a light lunch.
- Serve alongside a bowl of chilled gazpacho for the ultimate summer meal.
- Enjoy with kettle-cooked potato chips for classic sandwich nostalgia.
- Pair with iced tea, lemonade, or even a crisp white wine.
Make Ahead & Storage
This sandwich is best assembled fresh. However, you can prepare parts ahead of time:
- Toast the bread and let it cool, then store in an airtight container.
- Slice the tomatoes just before eating to preserve freshness.
- Keep mayonnaise handy for quick assembly.
If you must store, wrap the sandwich tightly in parchment paper and refrigerate for a few hours. Note: the bread will soften as it sits.
Frequently Asked Questions
What are heirloom tomatoes?
Heirloom tomatoes are non-hybrid tomatoes grown from seeds passed down through generations. They come in a variety of colors—red, yellow, purple, green—and have rich, unique flavors.
Can I use regular tomatoes instead?
Yes, but the flavor won’t be as complex. If heirlooms aren’t available, opt for beefsteak tomatoes or vine-ripened varieties.
Is mayonnaise essential?
For the traditional version, yes—it balances the acidity and juiciness of the tomato. However, you can substitute with Greek yogurt or mashed avocado for a lighter option.
Can I add protein to make it more filling?
Absolutely. Bacon, turkey, or even a fried egg can turn this simple sandwich into a hearty meal.
What’s the best bread to use?
Sourdough, brioche, or classic white bread work best. The key is to choose something that toasts well and won’t collapse under juicy tomatoes.
