Sweet potato crostini! Baked sweet potato slices with avocado, Caviar lime, and pomegranate are beautiful holiday appetizers. This post has been sponsored by Fruit Stand, but all opinions are my own. 

Baked sweet potato slices with avocado, finger lime, and pomegranate are healthy vegan appetizers, holiday appetizers, and sweet potato toast ideas.

With the holidays quickly approaching, it’s time to start planning our Thanksgiving menus. I can’t think of a better place to start than a beautiful holiday appetizer. Sweet potato crostini were inspired by one of my all-time most popular recipes, Sparkling Cranberry Brie Bites.

This time though, the bites are made with all whole-food ingredients like baked sweet potato slices, mashed avocado, two types of lime (including Caviar lime!), pomegranate, and cilantro. Avocado-lime sweet potato crostini are the most wonderful combination of flavor and texture, and perfect for holiday entertaining. 

Sweet potato crostini are like mini sweet potato avocado toasts. If you love avocado toast as much as I do, don’t miss our Avocado Toast ideas post. 

How to Make Sweet Potato Toast Crostini 

Sweet potato slices are brushed with olive oil before baking into sweet potato crostini, a healthy vegan appetizer.

Crostini, small toasts, are traditionally made with bread such as baguette. You can check out our Authentic Tomato Bruschetta for a traditional version. This sweet potato crostini recipe, however, is loaded with even more flavor and nutrition.

You’ll need about 2 medium sized sweet potatoes to make this simple appetizer. Slice the sweet potatoes crosswise, about 1/4″ thick. Try to cut even slices, as if they are too thin, they will burn. Brush with just a little olive oil, then season with a small pinch of salt and pepper. 

Bake Sweet Potato Slices

Bake the sweet potato slices until they are browned on the outside, flipping once, halfway through. Let them cool enough to handle, then they are ready to be dressed up!

There are so many possibilities when it comes to topping sweet potato toast or crostini. While some people like to use cheese such as brie or goat cheese, I love the combination of avocado and sweet potato.

A sprinkle of pomegranate arils, black salt, and lime caviar adds a pop of juicy freshness and color that makes them perfect for holiday celebrations. 

What are Caviar Limes?

One ingredient that makes this sweet potato crostini really special and worthy of any holiday menu is caviar lime. You can get caviar limes shipped fresh from Good Land Organics at FruitStand.com.

When you do, you’ll get 1/2 lb. Caviar Limes (about 20 – 25 limes), a gourmet recipe card, an exotic bonus spice, and this beautiful reusable canvas bag.

Though caviar limes typically last up to one week, your order of organic caviar limes will be protected by Apeel’s plant-derived solution, which should keep them fresh up to 3 times longer.

Also known as finger lime, this unique fruit is filled with lime juice pearls that resemble caviar! The pearls can range from clear to pink! Simply cut the caviar limes in half crosswise, and gently squeeze the lime juice caviar out.

Use caviar lime wherever you’d use lime or desire a bright fresh pop of flavor. They work well on desserts, tacos, cocktails, and more.
