Ingredients
- 12 slices of baguette
- 3 tablespoons of extra virgin olive oil, divided
- 2 large or 3 small ripe avocados, peeled and thinly sliced
- 1 ½ cups of diced tomato or sliced cherry tomatoes, red, yellow or both
- 3 tablespoons of minced herbs such as basil, parsley, dill, cilantro, or a combination
- Coarse salt to taste
How To Make Avocado Crostini
Step 1: Prepare the Baguette Slices
Start by preheating your oven to 400°F (200°C). While the oven is heating, slice the baguette into ½-inch thick slices. Arrange the slices on a baking sheet. Drizzle 2 tablespoons of extra virgin olive oil over the bread slices, making sure each piece is nicely coated. This will impart a lovely flavor and golden color.
Step 2: Toast the Bread
Place the baking sheet in the preheated oven and toast the baguette slices for about 10 minutes or until they are crispy and golden brown. Keep an eye on them to prevent burning. Once done, remove from the oven and set aside to cool slightly.
Step 3: Prepare the Avocados
While the bread is toasting, take your ripe avocados and slice them thinly. For added flavor, you can lightly mash them with a fork, but if you prefer the presentation of slices, you can skip this step. Place the sliced or mashed avocado into a bowl and sprinkle a pinch of coarse salt over them. This enhances their natural flavor.
Step 4: Assemble the Crostini
Now it’s time to assemble your crostini! Start by laying a slice of toasted baguette on a serving platter. Top each slice generously with avocado. Then, add the diced tomatoes or sliced cherry tomatoes on top of the avocado, allowing their vibrant color to shine through.
Step 5: Finish with Herbs and Drizzle
Sprinkle the minced herbs of your choice over the top of each crostini. The fresh herbs will not only add flavor but also elevate the overall presentation of your dish. Finally, for that extra touch, use the remaining tablespoon of olive oil to drizzle lightly over the finished crostini. This will add a luxurious mouthfeel and fragrance.
Expert Tips
- Choose ripe avocados: Make sure your avocados yield slightly when gently pressed to ensure optimal creaminess.
- Make it colorful: Using a mix of red and yellow cherry tomatoes not only adds flavor but also enhances visual appeal.
- Add a squeeze of lemon: A touch of lemon juice mixed with the avocado can prevent browning and adds brightness to the flavor.
- Serve immediately: These crostini are best served fresh for that perfect crunch and creamy texture.
Variations and Customizations
- Spicy Kick: Add thin slices of jalapeño or a sprinkle of red pepper flakes for a spicy twist.
- Cheesy Delight: Top with crumbled feta or grated Parmesan for added richness.
- Protein Boost: Add slices of cooked shrimp or smoked salmon for a protein-packed version.
- Seasonal Toppings: Depending on the season, try adding roasted red peppers, or a drizzle of balsamic reduction for a new flavor experience.
How to Store Leftovers
If you happen to have any leftover crostini (which is unlikely because they are so delicious!), it’s best to store the components separately. Keep the toasted baguette slices in an airtight container at room temperature for up to 2 days. Store the avocado mixture (if made ahead) in a container with a lid, and press plastic wrap directly onto the surface of the avocado to minimize browning. The diced or sliced tomatoes can also be stored separately in the fridge for a day or so. When ready to serve again, simply reassemble the crostini.
FAQ
Can I make avocado crostini ahead of time?
Yes, you can prepare the components ahead of time. Slice the baguette and toast it, then prepare the avocado and tomato mixture. Store them separately in airtight containers, then assemble just before serving for the best texture.
What are some good toppings for avocado crostini?
Good toppings include crumbled feta cheese, thinly sliced radishes, pickled onions, or even a drizzle of hot sauce. Fresh herbs like chives or scallions can also add an appealing touch.
How do I keep avocados from browning?
To prevent browning, you can add a squeeze of lemon juice to the avocado just after slicing or mashing. Additionally, covering it tightly with plastic wrap and minimizing exposure to air can help maintain its vibrant green color.
Can I use other types of bread for crostini?
Absolutely! While a baguette is traditional, you can use any type of bread you love. Sourdough or whole-grain bread can add a different flavor and texture to your crostini.
