Ingredient Breakdown

French baguette – The foundation for your crostini; slice it thinly for perfect crunch.

Butter & olive oil – Used to caramelize the onions gently and evenly without burning.

Yellow onions – Slowly cooked until soft and golden, bringing natural sweetness and depth.

Ripe pears – Add lightness and subtle sweetness that balances the onions perfectly. Choose firm but juicy pears like Bartlett or Bosc.

Thyme – Adds an earthy aroma that complements both the onions and pears.

Salt & pepper – Keep the flavors balanced and bright.

Soft cheese – Goat cheese, blue cheese, or brie all work beautifully as the creamy layer under the toppings.

Balsamic glaze (optional) – A light drizzle adds acidity and polish for presentation.

Step-by-Step Method

Preheat your oven to 375°F (190°C). Slice the baguette into ½-inch rounds and arrange on a baking sheet. Brush lightly with olive oil and toast for about 8–10 minutes, or until crisp and lightly golden. Set aside to cool.

Meanwhile, heat butter and olive oil in a skillet over medium heat. Add the sliced onions and cook slowly, stirring occasionally. After 10 minutes, sprinkle with a pinch of salt and reduce the heat slightly. Continue cooking another 15–20 minutes, until the onions turn deep golden and soft.

While the onions cook, slice the pears thinly. Toss them with a small squeeze of lemon juice to prevent browning.

To assemble, spread a thin layer of cheese on each toasted baguette slice. Add a spoonful of caramelized onions, then top with a pear slice. Sprinkle with fresh thyme and a touch of pepper.

If you’d like, finish with a drizzle of balsamic glaze for a glossy finish and a touch of acidity.

Serve warm or at room temperature.

Helpful Tips

• Be patient with caramelizing, slow cooking brings out the onions’ sweetness.
• Use firm pears, they’ll hold their shape on the crostini.
• Toast bread just before serving for the best texture.
• Try different cheeses, goat cheese for tang, brie for creaminess, or blue cheese for a sharper bite.
• Add nuts like toasted walnuts or pecans for extra crunch and flavor.

Serving Suggestions

These crostini make a wonderful appetizer or light meal when paired with a salad or soup.

They pair beautifully with my Creamy Cheddar Potato Chowder, the sweetness of the onions balances the savory soup perfectly.

If you’re serving them at a gathering, offer a sweet contrast with Honey-Roasted Pears with Mascarpone and Cranberry Drizzle for a cohesive menu.

They also make a great addition to brunch alongside Homemade Sandwich Bread and a fruit platter.

Storage & Make-Ahead

You can make the caramelized onions up to three days in advance, just refrigerate and reheat gently before using.

The baguette slices can be toasted several hours ahead and kept in an airtight container. Assemble the crostini just before serving to keep the bread crisp.

Leftovers can be stored in the refrigerator for one day and warmed slightly before serving, though they’re best enjoyed fresh.
