Heirloom Tomato Sandwich with Whipped Cottage Cheese

Recipe by Ailene

This ultimate summer lunch hinges on a thick layer of silky, herb-whipped cottage cheese and a sweet balsamic glaze to anchor juicy heirloom tomatoes. Toasting the sourdough and lightly curing the tomatoes first guarantees maximum flavor and crunch without any soggy bread.

  • Total Time13 minutes
  • Yield1 sandwich (serves 1) 1x

Ingredients

Scale

Whipped Herb Spread

  • ½ cup (113g) whole-milk (4%) cottage cheese
  • 2 tablespoons chopped fresh basil
  • ½ teaspoon grated lemon zest
  • ¼ teaspoon garlic powder
  • Small pinch of kosher salt

Sandwich

  • 2 thick slices sourdough bread
  • 1 teaspoon extra-virgin olive oil
  • 1 large heirloom tomato, cut into ½-inch slices
  • Kosher salt and freshly ground black pepper
  • 1 teaspoon balsamic glaze

Instructions

  1. Whip the spread: In a small food processor, combine the cottage cheese, fresh basil, lemon zest, garlic powder, and a pinch of salt. Process until completely smooth and creamy, about 1 to 2 minutes, stopping to scrape down the sides of the bowl once.
  2. Prep the tomatoes: Place the tomato slices on a paper towel-lined cutting board or plate. Season the top sides generously with kosher salt and black pepper. Let them rest for 5 minutes; this draws out excess moisture and concentrates their flavor.
  3. Toast the bread: Brush one side of each sourdough slice with the olive oil. Toast the bread in a skillet over medium heat, oiled-side down, until golden brown and crisp, about 2 to 3 minutes.
  4. Assemble the sandwich: Spread the whipped cottage cheese thickly over the un-toasted sides of the sourdough slices. Layer the seasoned tomatoes onto one slice, drizzle the balsamic glaze over the tomatoes, and close the sandwich. Cut in half and serve immediately.

Notes

  • Why it works: Salting the tomatoes on a paper towel is non-negotiable. It pulls out the water that would otherwise turn your bread to mush, while acting as a quick cure to amplify the tomato’s natural sweetness.
  • Make-ahead: You can blend the whipped herb cottage cheese up to 3 days in advance. Store it in an airtight container in the refrigerator to make lunch prep effortless all week.
