Prep the bread: Heat the oven to 400°F (200°C).
Slice the baguette into 1/2-inch rounds. Brush both sides lightly with olive oil and sprinkle with a pinch of salt.
Toast: Arrange slices on a sheet pan and bake 8–10 minutes, flipping halfway, until golden and crisp at the edges.
Load the processor: Add Kalamata olives, green olives, capers, garlic, lemon juice, herbs, and optional anchovy to a food processor.
Pulse, don’t puree: Pulse 6–10 times until the mixture is coarsely chopped. You want visible texture, not a paste.
Finish with oil: With the motor running briefly, drizzle in 2–3 tablespoons olive oil.
Stop when the tapenade looks glossy and spreadable.
Season: Add black pepper to taste. Adjust lemon or olive oil if needed. If it’s too salty, a little extra lemon helps balance.
Assemble: Spoon tapenade onto warm crostini.
Finish with a few herb leaves, lemon zest, or a tiny drizzle of olive oil.
Serve: Enjoy right away, or let the tapenade rest 15–30 minutes for the flavors to meld.
