Classic tomato-basil bruschetta with toasted baguette, garlic, extra-virgin olive oil, and a touch of balsamic. Fresh, fast, and perfect for parties or an easy appetizer.
Dice tomatoes and place in a colander for a few minutes to drain excess juice.
In a medium bowl, combine tomatoes, basil, minced garlic, extra-virgin olive oil, balsamic vinegar, salt, pepper, and red onion if using. Stir and let sit 10 minutes to marry flavors.
Heat oven to 425 F. Slice the baguette into 0.5 inch slices, arrange on a baking sheet, and brush both sides lightly with the 2 tablespoons olive oil.
Toast until golden at the edges, 5 to 8 minutes, flipping once if needed.
While hot, rub the top of each toast with the cut side of the halved garlic clove.
Spoon the tomato mixture over the toasts. For a melty option, add a slice of mozzarella to each toast, top with tomatoes, and return to the oven for 1 to 2 minutes to soften (optional).
Serve immediately. Drizzle a little extra balsamic and olive oil if desired.
Notes
Use ripe, meaty tomatoes (Roma or vine-ripened) for the best texture. Toast the bread just before serving to keep it crisp. If making ahead, keep the tomato mixture chilled and spoon onto toast at the last minute.
