Butternut Squash Crostini
Equipment
- 1 Sheet pan
- 1 knife
- 1 cutting board
- 1 spoon
- 1 food processor
- 1 Baking sheet
- 1 spatula
Ingredients
- 1 medium butternut squash
- 1 French baguette sliced and toasted
- 16 oz whole milk ricotta cheese
- ½ cup chopped toasted hazelnuts
- Balsamic glaze for drizzling
- Salt to taste
Instructions
- Preheat the Oven: Begin by setting your oven to 400°F (200°C). Preheating is essential for even roasting and ensures the squash develops a naturally sweet, caramelized flavor. Place a rack in the center of the oven so the squash cooks uniformly without burning.
- Prepare the Butternut Squash: Place the squash on a cutting board. Carefully slice off both ends to create a stable base. Cut the squash in half lengthwise and scoop out all seeds and fibrous strands using a spoon. Cleaning the cavity thoroughly helps the squash roast evenly and prevents a mushy texture.
- Season the Squash Halves: Lightly sprinkle salt over the cut sides of the squash. Salt enhances the natural sweetness and draws out excess moisture, allowing for better caramelization. Optionally, you can add a drizzle of olive oil to enrich the flavor and produce a slightly silkier texture.
- Roast the Squash: Place the seasoned squash halves cut-side down on a parchment-lined sheet pan. Roast in the preheated oven for about 30 minutes, or until a fork easily pierces the flesh. For larger squash, extend roasting time up to 60 minutes. Monitor closely to avoid overcooking or browning too much, aiming for tender, creamy flesh.
- Scoop Out the Flesh: Once roasted, remove the squash from the oven and let it cool slightly. Using a spoon, carefully scoop out the soft flesh and transfer it into a food processor. Discard or compost the skins. This ensures the puree is smooth and free from any fibrous strands.
- Puree the Squash: Process the roasted squash until completely smooth. If the mixture is too thick, add water one tablespoon at a time to achieve a creamy, spreadable consistency. Taste and adjust with a pinch of salt as needed. Smooth puree ensures every crostini bite is velvety and flavorful.
- Toast the Baguette Slices: While preparing the squash, slice the French baguette into ½-inch thick rounds. Arrange them on a baking sheet and toast in the oven until golden brown. Properly toasted slices provide a crunchy base that contrasts perfectly with creamy squash and ricotta.
- Assemble the Crostini Base: Spread a generous spoonful of the squash puree evenly over each toasted baguette slice. Ensure the layer covers the bread completely for balanced flavor and texture in every bite.
- Add Creamy Ricotta: Dollop a spoonful of ricotta cheese atop the squash layer. The ricotta adds richness and a subtle tang that complements the natural sweetness of the roasted squash. Smooth or leave rustic—it will still taste delicious.
- Drizzle with Balsamic Glaze: Lightly drizzle balsamic glaze over the ricotta and squash. The glaze adds a tangy-sweet depth and enhances presentation. Keep the drizzle thin to avoid overpowering the flavors of the squash and cheese.
- Sprinkle Toasted Hazelnuts: Top each crostini with chopped, toasted hazelnuts. The nuts provide crunch and a nutty flavor that balances the creamy textures. Toasting beforehand enhances aroma and richness, making every bite more complex and satisfying.
- Serve and Enjoy: Arrange the crostini on a serving platter and serve immediately while the bread is crisp and the squash slightly warm. Perfect for appetizers, holiday gatherings, or elegant snacks. Assemble just before serving for best results, or prep components ahead for easier meal prep.

Chef’s Secrets: Tips For Perfect Crostini
To elevate this appetizer, always choose a ripe butternut squash with smooth skin and a deep orange color—this ensures maximum sweetness and a creamy texture after roasting.
When roasting, placing the squash cut-side down helps the caramelization process, concentrating flavor.
For a more luxurious texture, blend the puree with a teaspoon of olive oil or a touch of cream.
Toast the baguette slices until golden brown but not overly dark to preserve their crunch without bitterness.
Finally, lightly toast hazelnuts before chopping to bring out their natural nuttiness, which adds depth to every bite.
Serving Suggestions: How To Impress Guests
These crostini are ideal as a starter for holiday dinners, cocktail parties, or casual get-togethers.
Arrange them on a platter garnished with fresh herbs such as thyme or rosemary for an elegant presentation.
Pair them with a crisp white wine or a sparkling beverage to balance the richness of the ricotta and sweetness of the squash.
For variety, consider adding a drizzle of honey for extra sweetness or a sprinkle of chili flakes for a subtle kick.
These little bites also work beautifully as a light snack or brunch accompaniment.
Storage Tips: Keep Crostini Fresh Longer
If you have leftover roasted squash puree, store it in an airtight container in the refrigerator for up to 3–4 days.
Toasted baguette slices can be kept in a sealed container at room temperature for 1–2 days to maintain crispness.
Assemble the crostini only before serving; otherwise, the bread will become soggy.
For longer storage, the squash puree can be frozen in small portions for up to 2 months.
Simply thaw in the refrigerator overnight and reheat gently before spreading on the bread.
Hazelnuts should be kept in an airtight container at room temperature to preserve their crunch and flavor.
Frequently Asked Questions
1. Can I use a different squash?
Yes! Kabocha, pumpkin, or acorn squash can be used as substitutes. Each variety has a slightly different sweetness and texture, so adjust roasting time until fork-tender.
2. Can I make this recipe vegan?
Absolutely. Substitute the ricotta with a plant-based ricotta or cashew cream, and ensure your baguette is dairy-free. The result will remain creamy and delicious.
3. How far ahead can I prepare this?
Roast the squash and toast the bread up to a day in advance. Store the puree in the refrigerator and assemble crostini just before serving for maximum freshness.
4. Can I freeze the crostini?
While assembled crostini do not freeze well due to soggy bread, the roasted squash puree can be frozen for up to 2 months.
Thaw in the refrigerator and reheat gently before use. Toasted baguette slices can be frozen separately and reheated in the oven before assembling.
5. How can I add more flavor to the crostini?
Enhance the flavor by adding fresh herbs such as thyme or sage to the squash puree, a dash of garlic powder, or a light drizzle of aged balsamic vinegar.
A sprinkle of sea salt or freshly cracked black pepper before serving also heightens the taste.
