Add all ingredients -except the olive oil, salt, and pepper- to a food processor.
Add 1 tablespoon of olive oil and blend until as smooth as possible.
Add another tablespoon of olive oil and blend again. If you’d like it creamier, add one more tablespoon. If your tapenade still seems dry, feel free to add another spoonful of olive oil.
Season to taste with pepper and, if needed, a bit of salt.
Tips
Bring to room temperature before serving for the best flavor.
