Bake the crostini

Slice the baguette and arrange the slices on sheet pans. Then, brush both sides of the bread with olive oil. Sprinkle them with salt and bake until golden and crispy.

Prepare the toppings

Then mash the avocado with fresh squeezed lemon juice and salt.

Pro-tip: I bought this stainless steel mighty masher for making baby food but it makes the best avocado masher! I love that it is small enough to fit inside of a small bowl!

Toss the arugula with more fresh squeezed lemon juice.

Assemble the crostini

First, spread all the crostini with mashed avocado. Then we’ll start adding more toppings.

First up: the classic preparation. Top with red pepper flakes, sea salt flakes, and freshly cracked black pepper.

Now do a few with just a sprinkle of everything bagel seasoning. So simple and so delicious.

Next, let’s make a few with balsamic and tomato. Slice a cherry tomato in half and arrange it on top of the avocado. Then, drizzle with balsamic glaze. Finish it with a pinch of sea salt flakes.

Last, lets top a few with lemony arugula. This one feels so fancy! Add a little mound of the lemony arugula on top of the avocado. Then sprinkle with sea salt flakes and freshly cracked pepper. Last, place a few pieces of shaved parmesan on top.

Pro-tip:  Use a vegetable peeler to shave small, thin pieces of parmesan.

Arrange them on a platter and serve!

Make ahead and storage tips

• You can bake the crostini up to 3 days ahead. Store the plain crostini in a sealed container at room temperature until ready to top and serve. 
• It’s best to make the avocado spread and add toppings shortly before serving. If you make them too far in advance, the avocado will brown, and the crostini will get soggy.
