Prepare the Paté
Sauté the Onions: In a skillet, heat olive oil and butter over medium heat. Add the chopped onions and cook until translucent, about 3-4 minutes.
Add Garlic and Livers: Stir in the minced garlic and cleaned chicken livers. Cook for about 5-7 minutes, stirring occasionally, until the livers are browned on the outside but still slightly pink inside.
Deglaze with Wine: Pour in the red wine, scraping any browned bits from the bottom of the pan. Cook for another 5 minutes until the wine has reduced and the livers are cooked through. They should be tender but not dry.
Blend the Mixture: Transfer the mixture to a food processor. Add capers (if using), parsley, salt, and pepper. Blend until smooth, adding a bit of olive oil if needed for creaminess.
Cool Down: Let the paté cool at room temperature for a few minutes before serving.
Make the Crostini
Preheat the Oven: Set your oven to 400°F (200°C).
Slice the Bread: Cut the baguette into 1/2-inch slices. Arrange them on a baking sheet.
Brush with Olive Oil: Lightly brush each slice with olive oil.
Toast the Bread: Bake in the preheated oven for 5-7 minutes, or until golden and crispy. Keep an eye on them to avoid burning!
Assemble
Spread the Paté: Once the crostini are cool, spread a generous amount of paté on each slice.
Garnish (Optional): Top with sliced olives, sun-dried tomatoes, or additional parsley for a burst of color and flavor.
Serve: Enjoy your Crostini Toscani con Paté warm or at room temperature.
