Roasted Delicate Squash Crostini Recipe

Preheat oven to 400°F (200°C). Arrange baguette slices in a single layer on a baking sheet.

Brush both sides of each slice lightly with 3 tbs olive oil. Season with 1 tsp sea salt and 1/2 tsp black pepper evenly across slices.

Bake in the preheated oven for 8–10 minutes, flipping once halfway, until edges are golden and crisp. Remove and let cool on a rack.

Reduce oven temperature to 425°F (220°C). Line a baking sheet with parchment paper.

Place halved or quartered delicate squash in a bowl. Add 2 tbs olive oil, 1 tsp fresh thyme leaves, 1 minced garlic clove, 1 tsp salt and 1/2 tsp black pepper. Toss to coat evenly.

Arrange squash pieces in a single layer, cut-side down where applicable, on the prepared baking sheet.

Roast for 18–22 minutes, until edges are caramelized and flesh is tender when pierced with a fork. If pieces are small, check at 12–15 minutes. Remove from oven and let cool slightly, then slice or chop into bite-sized pieces for topping.

While squash roasts, heat 1 tbs olive oil and 1 tbs butter in a large skillet over medium-low heat.

Add 2 cups thinly sliced yellow onion and 1/4 tsp salt. Cook, stirring every few minutes, lowering heat if onions begin to brown too quickly. After 10 minutes the onions will be soft and translucent.

Sprinkle 1/2 tsp sugar (or 1/2 tsp honey) over onions to promote caramelization. Continue to cook another 10–15 minutes, stirring frequently, until deep golden brown and sweet. If desired, stir in 1 tsp red wine or balsamic vinegar at the end to deglaze the pan and add brightness. Remove from heat and keep warm.

Spread about 1 to 1 1/2 tbs of room-temperature goat cheese on each crostini slice, covering the surface evenly.

Top each crostini with a small spoonful of caramelized onions (about 1 tbs) and 2–3 pieces of roasted delicate squash (or enough to sit attractively on the cheese).

Drizzle each crostini lightly with balsamic glaze (about 1/2 tbs per crostini).

Finish with a sprinkle of fresh thyme leaves or microgreens and, if using, a pinch of crushed pistachios or toasted walnuts for texture.

Arrange on a serving platter and serve warm or at room temperature.
