Roasted Red Pepper Crostini Recipe

Recipe by Pedro M. A. Neves

Roasted Red Pepper Crostini is a classic Italian appetizer featuring charred sweet peppers blended into a silky spread, served on toasted bread rounds. This elegant starter showcases the simplicity of Italian cuisine, where quality ingredients and proper technique create bold flavors. Perfect for entertaining, these crostini can be prepared ahead and assembled just before serving.

Ingredients

• 4 medium red bell peppers (approximately 600g)
• 1 ciabatta loaf or Italian bread
• 3 tablespoons extra virgin olive oil, divided
• 2 cloves garlic, minced
• 30g roasted pine nuts
• 15g fresh basil leaves
• 10ml balsamic vinegar
• 5g sea salt
• 2g black pepper
• 30g aged Parmigiano-Reggiano cheese

Instructions

1. Preheat oven to 200°C (400°F). Place whole red peppers on a rimmed baking sheet and roast for 25-30 minutes, turning halfway through, until the skin is completely blackened and charred.

2. Remove peppers from heat and immediately transfer to a covered bowl for 10 minutes to steam, which loosens the skin.

3. Once cooled slightly, peel away the charred skin under cool running water, working gently to preserve the tender flesh. Remove seeds and stems.

4. Slice bread into 12-16 slices approximately 1.25cm thick. Arrange on a baking sheet, brush lightly with 1.5 tablespoons olive oil, and toast at 180°C (350°F) for 8-10 minutes until golden and crisp.

5. In a food processor, combine roasted peppers, minced garlic, pine nuts, 1.5 tablespoons olive oil, balsamic vinegar, salt, and pepper. Pulse until the mixture reaches a chunky-smooth consistency, not a fine purée.

6. Tear fresh basil leaves and gently fold into the pepper mixture with a wooden spoon.

7. Spread approximately 15-20ml (1-1.5 tablespoons) of the red pepper mixture onto each toasted bread slice, using the back of a spoon to distribute evenly.

8. Using a vegetable peeler or microplane, shave thin curls of Parmigiano-Reggiano over each crostini immediately before serving.

Substitutions

• Substitute pine nuts with toasted walnuts or almonds for a different flavor profile and reduced cost
• Replace fresh basil with fresh oregano or parsley if basil is unavailable
• Use gluten-free bread to make the crostini suitable for gluten-free diets
• Omit cheese entirely or substitute with a dairy-free nutritional yeast for vegan preparation

Tips

• Prepare the roasted pepper mixture up to 2 days ahead and store in an airtight container in the refrigerator; assemble crostini within 1 hour of serving to maintain crispness
• For deeper flavor, add a small anchovy fillet to the food processor when processing the peppers—a traditional Italian technique
• Toast the bread slices only once to maintain their crispness; if prepared too far in advance, they will soften from the moisture in the spread
• Serve at room temperature rather than chilled to allow the full complexity of the roasted pepper flavor to develop on the palate

Crostini are foundational to Italian antipasto culture, particularly in Tuscany and central Italy where bread is treated as a blank canvas for seasonal vegetables and local flavors. This version celebrates the Mediterranean reverence for roasted peppers, transforming a simple summer vegetable into an elegant showcase of ingredient quality and minimal preparation.
