Ingredients
  

For the Roasted Squash
  • 1 medium butternut squash (about 2–2.5 lb), peeled, seeded, and cut into 1-inch cubes
  • 3 tbsp olive oil, divided
  • ½ tsp salt, plus extra to taste
  • ¼ tsp freshly ground black pepper
  • 1 tsp fresh thyme leaves (or 1/2 tsp dried)
  • 1 tsp maple syrup or honey (for roasting, optional)
For the Ricotta Spread
  • 8 oz whole-milk ricotta (for vegan option, use cashew ricotta)
  • 1 tsp zest of 1 lemon (about 1 tsp)
  • 1–2 tbsp lemon juice, to taste
  • 1 clove garlic, finely grated or pressed
For the Crostini Assembly
  • 12–16 slices baguette, about 1/2-inch thick
  • 8–12 leaves fresh sage
  • 2 tbsp unsalted butter (or olive oil for dairy-free)
  • 1–2 tsp honey or maple syrup for finishing
  • Crushed red pepper flakes or smoked paprika (optional, for garnish)
  • Flaky sea salt (for finishing)

Method
 

Preheat and prepare
  1. Preheat your oven to 425°F (220°C). Line a baking tray with parchment or a silicone mat for easy cleanup.
  2. Toss the cubed butternut squash with 2 tablespoons of olive oil, 1/2 tsp salt, black pepper, thyme, and 1 tsp maple syrup or honey if using. Spread in a single layer on the tray.
  3. Tip: A hot oven and a single layer are crucial for caramelized edges. Use a thermometer to confirm oven temperature.
Roast the squash
  1. Roast for 25–30 minutes, stirring once halfway through, until the squash is golden and tender.
  2. Variation: You can boil the squash in salted water for 10–12 minutes instead of roasting.
  3. Tip: For extra flavor, add a split garlic clove or a sprig of rosemary to the tray while roasting.
Make the ricotta base
  1. In a bowl, whisk together the ricotta, lemon zest, lemon juice, grated garlic, a pinch of salt, and 1 tablespoon of olive oil. Adjust to taste.
  2. Tip: For a creamier texture, pulse the ricotta in a food processor.
Prepare the crostini
  1. Brush both sides of the baguette slices with the remaining olive oil or a light smear of butter. Arrange on a baking tray and toast in the oven at 400°F (200°C) for 8–10 minutes.
  2. Tip: You can toast the bread alongside the squash during the last 8–10 minutes.
Crisp the sage
  1. In a small skillet over medium heat, add butter or olive oil and fry the sage leaves until crisp.
  2. Tip: Watch the sage carefully, it burns quickly.
Assemble the crostini
  1. For a spread, place roasted squash in a blender and pulse until smooth. Spoon a dollop of lemon ricotta onto each crostini, then top with squash.
  2. If you prefer chunks, heap small cubes of roasted squash onto the ricotta.
  3. Drizzle with honey or maple syrup, add a sage leaf, and finish with sea salt and red pepper flakes.

Notes

Store roasted squash in the refrigerator for up to 4 days, and whipped ricotta for 3 days. Toasted baguette is best eaten the day of. For a vegan version, use cashew ricotta and olive oil.
