Recipe FAQs

Crostini, meaning “little toasts” in Italian, is a classic appetizer with ancient origins. Initially, people grilled bread and drizzled it with olive oil. This concept evolved, giving rise to variations like sausage crostini. Though its exact origin is unclear, this contemporary twist draws inspiration from Italy’s culinary heritage, emphasizing the tradition of combining simple, fresh ingredients for generations.

Serving them warm is ideal, as it enhances the flavors. However, if you’re preparing them ahead of time, room temperature is still delicious, especially if the sausage mixture has robust flavors.

Serving Suggestions

Wine Pairing – Pair your sausage crostini with a medium to full-bodied red wine such as Chianti or Sangiovese. The wine’s robust character complements the savory sausage and balances the dish’s flavors. Try a crisp Pinot Grigio for a refreshing contrast for a white wine option.
Make it a meal -Serve alongside a fresh arugula salad with a lemon vinaigrette. The crisp greens complement the richness of the sausage crostini.
Antipasto platter – Include your crostini on an antipasto platter with various olives, cheeses, and marinated vegetables for a diverse and satisfying spread.
Tomato bruschetta – Add a burst of freshness by serving tomato bruschetta on the side. The bright flavors of tomatoes and basil balance the savory notes of the sausage.

Storage and Reheating Instructions

Storage

Refrigeration – If you have leftoves, allow them to cool to room temperature. Place them in an airtight container or wrap them tightly in plastic wrap.
Refrigerator shelf life – Stored properly, sausage crostini can be refrigerated for up to 2 days. Beyond this timeframe, the bread may lose its crispiness.

Reheating

Oven method – Preheat your oven to 350° Fahrenheit (175° Celsius). Place the crostini on a baking sheet and bake for 5-8 minutes, or until heated. This helps maintain the bread’s crispiness.
Avoid the microwave – While the microwave is a quick option, it may make the bread soggy. If using a microwave, do it quickly to prevent excessive softening.

Remember, the key is to strike a balance between reheating thoroughly and preserving the original crispness of the bread. Adjust the reheating time based on your preference for a crunchy or softer texture.
