Ingredients
This simple recipe requires just a few basic ingredients! Here's what you'll need:
- Avocado - You'll need two large avocados for the guacamole-like topping. I recommend using Haas avocados, which have the best flavor. Tip: For the creamiest texture, make sure your avocados are perfectly ripe (they should have a little give when you gently squeeze them).
- Garlic - A little fresh garlic adds tons of flavor to the mashed avocado.
- Lemon - You'll also add some fresh lemon juice to the topping. It's enhances all the other flavors!
- Tomatoes - This recipe calls for grape tomatoes. I used a colorful mix of tomatoes, but regular grape tomatoes or cherry tomatoes will also work great.
- Seasoning - You'll season the avocado with kosher salt. And a sprinkle of everything bagel seasoning is the perfect finishing touch!
- Crostini - For the base, you'll make homemade crostini (don't worry, it's super easy!) with a baguette, extra virgin olive oil, and kosher salt.
This recipe is naturally vegetarian, vegan, and dairy free, and it's easy to make gluten free, too. Check out the Variations section below for help!
You'll Also Need
Grab a serrated knife to slice the bread and tomatoes, a fork to mash the avocado, and a pastry brush to coat the crostini with olive oil. You'll also need a baking sheet to toast the bread.
How to Make Crostini with Avocado
This Avocado Toast Appetizer couldn't be easier to make! You'll find a detailed recipe card below, but here's a quick overview of the steps:
- Bake crostini. Start by thinly slicing the bread, then brush it with olive oil and sprinkle with salt. Bake the crostini just until it's crisp throughout and lightly browned.
- Prep tomatoes. While the toasts bake, cut each of your tomatoes into three slices.
- Make avocado topping. Next, mash the avocado together with the garlic, lemon juice, and salt. Tip: For a chunkier topping, mash the avocado less. For a smoother topping, mash the avocado more.
- Top crostini with avocado. When the crostini has cooled, top each toast with a dollop of the mashed avocado.
- Add tomatoes. Place three tomato slices on top of the avocado.
- Sprinkle with seasoning. Finish the crostini by adding a generous sprinkling of everything bagel seasoning.
Alrighty, it's time to enjoy your homemade Avocado Crostini! Wasn't that simple to make?
Variations
This recipe is endlessly customizable! Here are a few ideas to try:
- Rainbow - For a colorful, rainbow-like effect, use multi-colored tomatoes instead of red tomatoes, like I did!
- Cooked Tomatoes - Replace the fresh tomatoes with Roasted Grape Tomatoes or Roasted Cherry Tomatoes.
- Other Veggies - Swap out the tomatoes for other fresh veggies, like chopped cucumber, sliced radishes, or chopped green onions. Cooked vegetables, such as corn, mushrooms, or zucchini also make a delish topping. For an extra zing of flavor, top the toasts with pickled red onions, sliced jalapeños, or kimchi.
- Eggs - Top the Tiny Avocado Toasts with sliced hard boiled eggs or mini fried eggs (use quail eggs).
- Nuts + Seeds - Instead of everything bagel seasoning, top the appetizer with finely chopped walnuts, pecans, pistachios, almonds, pepitas, sesame seeds, or hemp seeds.
- Lime - Use lime juice instead of lemon juice.
- Cheese - Add an extra layer of flavor by sprinkling crumbled feta, goat cheese, sharp cheddar, or queso fresco over the top.
- Herbs + Spices - Top the toasts with fresh herbs (like basil, dill, cilantro, or tarragon), or add a sprinkle of crushed red pepper flakes, adobo seasoning, shichimi togarashi, or Tajín.
- Sauces - Drizzle on a favorite sauce, such as Homemade Pesto, balsamic glaze, Black Bean and Corn Salsa, or Romesco Sauce. If you like spicy flavors, garnish the crostini with chili crisp, hot sauce (I like Secret Aardvark), sriracha, or hot honey.
- Crostini - I used a baguette for this recipe, but the crostini can also be made with other breads, such as focaccia or sourdough. If needed, cut the bread into smaller pieces (just big enough for two bites).
- Gluten Free - Make the crostini with a GF baguette, and if you have an allergy, double check all other labels.

Storage
This Avocado Tomato Crostini is best served shortly after it's made. However, you can make the toasts, then store them in an airtight container (they'll taste freshest when eaten within two to three says, but will keep for up to two weeks). You can also slice the tomatoes a couple hours in advance.

Frequently Asked Questions (FAQs)
Crostini are thinly sliced pieces of bread (usually from a baguette) that have been brushed with olive oil, then baked until crunchy. The crispy toasts are then served as an appetizer with different toppings, including as veggies, cheeses, dips, and more.
Crostini and bruschetta are similar, but different, types of Italian toast. Crostini is usually made with a baguette that's been thinly sliced, brushed with olive oil, and baked until crisp. Bruschetta on the other hand, is typically made with rustic-style bread, sliced a little thicker, and rubbed with garlic. Traditionally, bruschetta is cooked on the grill, which gives the finished toasts a little char and a slightly smokey flavor.
Crostini can be served hot, cold, or at room temperature, depending on the toppings. It's frequently eaten at room temperature, which makes it perfect for parties!
Crostini should be crunchy, but not so hard that it hurts your mouth. If your Crostini is too hard, slice the bread thinner (about ¼-inch thick is best), or pick a bread with a lighter texture.
Crostini, which means "little toasts" in Italian, are thin slices of toasted bread. The singular version of crostini is crostino.
