In a food processor, combine the ricotta, basil leaves, lemon zest, lemon juice, olive oil, salt, and black pepper. Blend until completely smooth and creamy. Taste and adjust seasoning if needed.
Lightly brush the baguette slices with olive oil and toast until golden and crisp, either in the oven or on a grill pan.
Spread or pipe a generous layer of the whipped ricotta onto each toasted baguette slice.
Top with torn pieces of prosciutto and garnish with fresh herbs or micro greens
Finish with a light sprinkle of fresh lemon zest and serve immediately.
