I recently served these Avocado Caprese Crostini for my son’s second birthday and they were such a hit!

Flash forward a couple of years to my son’s second birthday party…I needed to come up with an easy appetizer and my mom’s recipe immediately popped into my brain. This is my attempt to recreate it and adapt it into a recipe of my own. I hope you love it just as much as we do!

How to Make Caprese Crostinis With Avocado

STEP 1 – Prep the Crostinis

Slice the baguette into rounds, about 1/2 inch thick. Drizzle olive oil on a baking sheet lined with parchment paper and place the sliced baguette rounds on top. Drizzle olive oil on top of the rounds and sprinkle with sea salt. Bake in the oven at 400 degrees Fahrenheit for 10 minutes.

STEP 2 – Assemble the Crostinis

Using a fork, mash avocado onto the top of each baked crostini. Sprinkle sea salt on top of the avocado. Next, layer each crostini with a basil leaf (you may need to tear the leaf in half to fit on the crostini), followed by a mozzarella slice, and then 2 halved cherry tomatoes.

STEP 3 – Add the Final Touches

Drizzle a tiny bit of olive oil across all of the crostini followed by a balsamic glaze. Sprinkle a little bit of shredded basil on top for a nice presentation and serve.
