BLT Crostini Appetizer by Jessica Hansen is a modern twist on the timeless sandwich, where the essential ingredients of a BLT are served on toasted slices of baguette or a similar bread. Crostini, which means “little toasts” in Italian, are ideal for serving as appetizers or snacks.
Ingredients:
- 1 baguette, sliced into 1/2-inch thick rounds
- Olive oil, for brushing
- Salt, to taste
- 8 slices of crispy bacon, broken into smaller pieces
- 1 cup cherry tomatoes, halved or quartered depending on size
- 1/2 cup lettuce (such as romaine or butter lettuce), thinly sliced or torn
- 1/2 cup mayonnaise
- 1 garlic clove, minced
- 1 tbsp fresh lemon juice
- Freshly ground black pepper, to taste
- Optional: Fresh basil or chives for garnish
Instructions:
- Prepare the Crostini:
- Preheat your oven to 375°F (190°C).
- Arrange the baguette slices on a baking sheet, brush both sides lightly with olive oil, and season with a pinch of salt.
- Toast in the oven until golden brown, about 5-7 minutes per side. Remove and let cool.
- Prepare the BLT Topping:
- In a mixing bowl, combine halved cherry tomatoes, sliced lettuce, and broken bacon pieces. Gently toss to combine.
- Prepare the Garlic Aioli:
- In a small bowl, combine mayonnaise, minced garlic, and lemon juice. Stir well until smooth. Season with salt and freshly ground black pepper to taste.
- Assemble the Crostini:
- Spread a generous amount of garlic aioli on each toasted baguette slice.
- Top with the BLT mixture, pressing slightly to adhere.
- Optional: Garnish with fresh basil or chives.
- Serve & Enjoy:
- Arrange the BLT crostini on a serving platter and serve immediately. They are best consumed fresh to retain the crispness of the toast and the bacon.

Serving Suggestions:
- Pair these BLT crostini with a refreshing iced tea or white wine for an elegant appetizer experience.
- These can also be served alongside other crostini varieties for a diverse appetizer spread.
This appetizer perfectly encapsulates the essence of a BLT but in a bite-sized and elegant format, making it a delightful choice for parties, gatherings, or any casual get-together.
