Instructions

Preheat Oven and Prepare Brussels Sprouts

Set your oven to 400°F to ensure it’s hot enough for roasting. Toss sliced Brussels sprouts with 2 tablespoons of olive oil, nutmeg, sea salt, and pepper in a bowl, coating evenly. This step infuses the sprouts with warm spices and seasoning for caramelization.

Roast Brussels Sprouts

Spread the seasoned Brussels sprouts on a foil-lined baking sheet in a single layer. Roast for about 20 minutes, stirring once halfway through to ensure even browning and tenderness. Roasting brings out their natural sweetness and crisp edges.

Prepare Cheese Spread

In a food processor, combine crumbled feta and whipped cream cheese. Process until smooth and creamy, creating a spread that’s tangy with a luscious texture, perfect for layering on toasted bread.

Toast the Baguette Slices

Arrange bread slices on a foil-lined baking sheet and brush both sides lightly with the remaining olive oil. Broil slices 1-2 minutes until they develop a golden crust, which adds crunch and supports the toppings without becoming soggy.

Assemble Crostini with Toppings

Spread a generous layer of the cheese mixture on each toasted bread slice. Top evenly with roasted Brussels sprouts, ensuring each bite has a good balance of creamy and vegetable elements.

Add Gruyere and Broil

Sprinkle shredded Gruyere cheese over the sprouts. Return the baking sheet to the broiler, positioning 5-6 inches from the heat source. Broil 1-2 minutes until the cheese melts and starts to brown, adding a rich depth and appealing color.

Finish and Serve

If desired, drizzle garlic oil over each crostini for an extra layer of flavor. Serve immediately while warm to enjoy the perfect combination of crispy, creamy, and roasted textures.

You Must Know

  • Watch the broiler closely to prevent cheese from burning; a quick broil creates the best melt.
  • Trim Brussels sprouts thoroughly to remove tough outer leaves for smoother roasting.
  • Using a food processor helps blend the cheeses into a perfectly smooth spread.

Storage Tips

Store leftover crostini in an airtight container in the refrigerator for up to 2 days. Reheat briefly in the oven to restore crispness before serving.

Serving Suggestions

Serve these crostini as an elegant appetizer alongside a crisp white wine or sparkling water. They also pair well with fresh greens or a light soup for a complete lunch or brunch.

Professional Tips

  • Use day-old baguette slices for optimal crispiness when toasting.
  • Customize by adding toasted nuts or herbs like thyme for extra flavor complexity.
  • Roast Brussels sprouts evenly by keeping them in a single layer and stirring halfway.
