Roast tomato and pesto crostini
The combination of toppings in this crostini appetizer recipe is OUT OF THIS WORLD: A generous slather of fresh homemade lemony basil pesto topped with roasted cherry and grape tomatoes and drizzled with a sweet and tangy balsamic glaze.
Roasting the tomatoes brings out their sweetness and juiciness. I like to roast whole grape or cherry tomatoes because (1) it’s easier than having to slice them and (2) leaving the tomatoes whole means you get a nice burst of flavor when you bite into the crostini.
It’s OK if the tomatoes burst while they are roasting!
Fresh lemony basil pesto
I really recommend making fresh pesto for this recipe instead of buying the jarred stuff. The pesto is what really makes this recipe.
Luckily, pesto is really easy to make and you can make it while the tomatoes are roasting. Just place all the ingredients in a small food processor and pulse or process until you get to your preferred pesto texture. I like to leave the pesto chunky for more texture and flavor.
I add a little extra lemon juice to make a lemony pesto – I think it’s extra delicious this way.
You can skip the pine nuts or Parmesan cheese if you have allergies – the pesto still comes out great thanks to all the fresh basil.
I finish this pesto crostini with a generous drizzle of balsamic glaze. Balsamic glaze is just balsamic vinegar that is cooked down and reduced with some sugar added. It has almost a syrupy consistency and it is SO GOOD. It has a nice balsamic tang which is balanced out by the sweetness. It is fantastic on pesto crostini with tomatoes.
Luckily this stuff is just as good bottled as it is when you make it from scratch, so just get it here.
