Preheat your oven to 400°F (200°C).

Brush the baguette slices with 2 tablespoons of olive oil and place them on a baking sheet.

Toast in the oven for 5 minutes until golden brown and crispy, then let them cool slightly.

In a small bowl, mix the ricotta cheese with the lemon zest, half the lemon juice, and black pepper.

Spread a generous layer of the lemon ricotta mixture onto each toasted baguette slice.

Top each crostini with a folded slice of beef.

Drizzle with the remaining 1 tablespoon of olive oil, the rest of the lemon juice, and garnish with fresh chopped basil before serving.
