Crostini are thin, toasted slices of Italian bread, typically brushed with olive oil and rubbed with garlic, then topped with any number of savory ingredients. They are the classic Italian antipasto, perfect for parties, appetizers, or a light lunch. These recipes work because they balance texture—crisp bread against creamy or juicy toppings—and flavor, using simple, high-quality ingredients that come together quickly.
Ingredients
- 1 baguette (about 12 oz / 340 g), sliced into 1/2-inch (1.25 cm) rounds
- 1/4 cup (60 ml) extra-virgin olive oil, plus more for drizzling
- 1 garlic clove, peeled and halved
- For the Tomato-Basil Topping:
- 1 cup (150 g) cherry tomatoes, diced
- 1/4 cup (10 g) fresh basil leaves, thinly sliced
- 1 tbsp (15 ml) balsamic vinegar
- 1/4 tsp salt, plus more to taste
- For the White Bean & Rosemary Topping:
- 1 can (15 oz / 425 g) cannellini beans, drained and rinsed
- 2 tbsp (30 ml) olive oil
- 1 tbsp (15 ml) lemon juice
- 1 small garlic clove, minced
- 1 tsp fresh rosemary, finely chopped
- Salt and black pepper to taste
- For the Mushroom & Thyme Topping:
- 2 cups (200 g) cremini mushrooms, finely chopped
- 2 tbsp (30 ml) olive oil
- 1 shallot, minced
- 1 tsp fresh thyme leaves
- 2 tbsp (30 g) unsalted butter
- Salt and black pepper to taste
Instructions
- Preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet in a single layer. Brush both sides lightly with olive oil.
- Bake for 5–7 minutes, then flip the slices and bake for another 3–5 minutes, until golden and crisp. The total baking time is about 10 minutes. Remove from the oven and let cool slightly.
- While the bread is still warm, rub each slice with the cut side of the garlic clove. Set aside.
- Make the tomato-basil topping: In a small bowl, combine the diced tomatoes, basil, balsamic vinegar, and 1/4 tsp salt. Stir gently and set aside to marinate while you prepare the other toppings.
- Make the white bean topping: In a medium bowl, mash the cannellini beans with a fork until chunky but spreadable. Stir in the olive oil, lemon juice, minced garlic, rosemary, and salt and pepper to taste.
- Make the mushroom topping: Heat the olive oil in a skillet over medium heat. Add the shallot and cook for 2–3 minutes until soft. Add the mushrooms and thyme, and cook for 6–8 minutes, stirring occasionally, until the mushrooms are browned and their liquid has evaporated. Remove from heat, stir in the butter, and season with salt and pepper.
- Assemble the crostini: Spoon or spread each topping onto the toasted bread slices. For the tomato topping, use a slotted spoon to avoid excess liquid. Drizzle with a little extra olive oil and garnish with fresh herbs if desired.
- Serve immediately while the bread is still crisp.
Tips
- Bread choice: Use a good-quality baguette or Italian bread like ciabatta. Avoid soft sandwich bread, which won’t crisp up properly. If the bread is very fresh, let the slices dry out on the counter for 30 minutes before toasting.
- Don’t over-wet the bread: If your tomato topping is too juicy, it will make the crostini soggy. Drain the tomatoes after marinating or use a slotted spoon when topping.
- Make ahead: You can toast the bread and prepare the toppings up to a day in advance. Store them separately in the refrigerator and assemble just before serving.
- Garlic rubbing: The garlic rub is what gives crostini that classic flavor. Don’t skip it—but if you prefer a milder taste, use a whole garlic clove and just lightly brush it over the bread.
Serving Suggestions
Serve crostini as an appetizer with a glass of Italian wine, such as a light Pinot Grigio or a Chianti. They pair beautifully with a bowl of olives, marinated artichokes, or a simple green salad. For a larger spread, offer a cheese board with fresh mozzarella, prosciutto, and figs. Crostini are also excellent alongside soups like minestrone or tomato basil.
Variations
- Classic bruschetta: Use larger slices of country bread and top with the tomato-basil mixture only.
- Fig and goat cheese: Spread soft goat cheese on the toasted bread, then top with sliced fresh figs and a drizzle of honey.
- Roasted red pepper and ricotta: Blend roasted red peppers with a little olive oil and spread over ricotta-topped crostini.
- Anchovy and olive: For a salty, umami version, top with a few anchovy fillets and black olive tapenade.
- Eggplant caponata: Spoon a spoonful of caponata (sweet-and-sour eggplant) over the bread for a Sicilian twist.
Storage and Reheating
Crostini are best eaten fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. The bread will soften, so to reheat, place them on a baking sheet and warm in a 350°F (175°C) oven for 5–7 minutes until crisp again. Toppings can be stored separately in the refrigerator for up to 3 days. Do not freeze assembled crostini, as the texture will suffer.
Frequently Asked Questions
Can I use gluten-free bread? Yes, gluten-free baguettes work well, but they may toast faster, so keep an eye on them. The texture will be slightly different but still crispy.
Can I make these ahead for a party? Absolutely. Toast the bread and prepare the toppings up to a day ahead. Keep them separate and assemble within an hour of serving to prevent sogginess.
What if I don’t have a baguette? Any crusty Italian bread, like ciabatta or sourdough, works. Slice it into similar-sized pieces and adjust the baking time as needed.
Can I use dried herbs instead of fresh? Yes, but use about one-third of the amount. Dried herbs are more concentrated. Add them to the toppings early so they have time to rehydrate.
Why are my crostini soggy? This usually happens because the toppings are too wet or the bread wasn’t toasted enough. Make sure to bake the bread until fully crisp and drain any watery toppings.
Can I grill the bread instead of baking? Yes, grilling gives a nice smoky flavor. Grill the slices over medium heat for 1–2 minutes per side, watching closely to prevent burning.
