Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet and toast them in the oven until golden brown, about 8 10 minutes. In a medium bowl, combine diced tomatoes, minced garlic, salt, and black pepper. Gently mix to incorporate the flavors. Prepare the basil aioli by whisking together mayonnaise, finely chopped fresh basil, Parmesan cheese, and a pinch of salt in a small bowl until smooth. Once the baguette slices are toasted, remove them from the oven and let them cool slightly. Spread a layer of basil aioli on each slice. Top each piece with a spoonful of seasoned tomato mixture. Drizzle with olive oil and balsamic vinegar to enhance the flavors. Garnish with fresh basil leaves before serving.
Chef’s Insight
For a burst of color and additional flavor, use a variety of tomato types in your dish.
