Hey there, food enthusiasts! Today, I’m thrilled to share a delightful recipe that brings together the freshness of avocado and the rich flavor of crabmeat on a crunchy crostini. This Crab and Avocado Crostini is not just a crowd-pleaser but also a quick and elegant appetizer that’s perfect for any gathering.

I vividly remember the first time I made these crostinis. It was a warm summer evening, and my family had gathered for a backyard barbecue. I wanted to prepare something light yet impressive, and these crostinis turned out to be a hit. Watching everyone savor each bite, with smiles and nods of approval, made me realize that sometimes the simplest recipes can bring the most joy.

What I love most about this recipe is its versatility. If you’re not a fan of yellow pepper, you can easily substitute it with red or even roasted bell peppers for a different flavor profile. For those who prefer a bit of heat, a finely diced jalapeño can add a wonderful kick. And if Meyer lemons aren’t available, a regular lemon or even lime juice works just as well.

The combination of creamy avocado, sweet crabmeat, and the tangy lemon vinaigrette on a crisp, olive-oil-brushed baguette is truly irresistible. Whether you’re hosting a dinner party, a casual get-together, or just treating yourself to something special, these crostinis are sure to impress.

So, let’s get started and bring a touch of gourmet flair to our kitchens with this easy-to-make yet sophisticated appetizer. Trust me, once you try these Crab and Avocado Crostinis, they’ll become a staple in your recipe collection, just as they have in mine.

How to Make Crab and Avocado Crostini


  • 8 ounces crabmeat, lump
  • 1 yellow bell pepper, diced with seeds removed
  • 1 loaf of thin French baguette or ficelle
  • 1 diced avocado, pitted and halved
  • 1 finely diced shallot
  • 1/4 cup plus 3 tablespoons olive oil
  • Juice of 1 Meyer lemon
  • Salt and freshly ground black pepper


  1. Preheat your oven to 400°F. Slice the bread into pieces that are 1/2 inch thick. Lightly brush each slice with 3 tablespoons of olive oil.
  2. Arrange the oiled bread slices on a baking sheet and bake until they are lightly toasted, around 8 minutes. Let them cool after removing them from the oven.
  3. In a large bowl, whisk together the juice of the Meyer lemon, 1/4 cup olive oil, and salt and pepper to taste. Set this mixture aside.
  4. Add the diced yellow bell pepper, avocado, shallot, and lump crabmeat to the bowl with the lemon vinaigrette. Toss everything gently to keep the crabmeat intact.
  5. Spoon about a tablespoon of the crab mixture onto each toasted bread slice. Arrange the crostini on a serving platter before serving.

Can I use regular lemons instead of Meyer lemons for this recipe?

Yes, you can use regular lemons if Meyer lemons are not available. However, Meyer lemons are sweeter and less acidic, so you might want to add a pinch of sugar to the lemon juice if using regular lemons.

Is there an alternative to using lump crabmeat?

If lump crabmeat is not available or too expensive, you can use canned crabmeat as a substitute. Make sure to drain it well before adding it to the mixture to avoid excess moisture.

How can I prevent the avocado from browning?

To prevent the avocado from browning, ensure it is well coated in the lemon vinaigrette immediately after dicing. The acidity in the lemon juice helps keep the avocado fresh and green.

Can I prepare the crab mixture ahead of time?

Yes, you can prepare the crab mixture a few hours ahead and refrigerate it. However, it’s best to add the avocado just before serving to ensure it stays fresh and vibrant.

What should I do if I don’t have a shallot?

If you don’t have a shallot, you can substitute it with a small amount of finely diced red or white onion. Keep in mind that onions have a stronger flavor, so use sparingly.

Can I grill the bread instead of toasting it in the oven?

Absolutely, you can grill the bread slices for a smoky flavor. Brush them with olive oil and grill on medium heat until they are lightly toasted and have grill marks.
