Preheat the oven (electric cooker: 180 °C/circulating air: 160 °C/gas: see manufacturer) and line a baking tray with baking paper. Cut the baguette into slices about 1 cm thin. Place on the baking tray and drizzle 5-6 tbsp. oil over it. Season with salt and pepper. Roast in a hot oven for about 6 minutes, turn carefully and continue baking for about 6 minutes. Remove, allow to cool and store in a tightly closed tin until use.
In the meantime grate the Parmesan finely. Cut olives into slices. Chop tomatoes coarsely. Wash basil, shake dry and chop leaves coarsely. Mix all ingredients with ricotta. Season with salt and pepper.
To serve, spread the ricotta cream loosely on the toasted baguette slices. Drizzle with a little oil and sprinkle with cress.
