Ingredients for Blue Cheese and Caramelized Onion Bruschetta

Here’s what you’ll need to make 8 slices of blue cheese and caramelized onion bruschetta:

  • 8 slices of baguette or rustic bread
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons olive oil, plus extra for brushing bread
  • 1 tablespoon butter
  • 1 teaspoon sugar (optional, for extra sweetness)
  • 1/2 cup crumbled blue cheese
  • Fresh thyme leaves for garnish
  • Salt and freshly ground black pepper to taste

Step-by-Step Guide to Making Blue Cheese and Caramelized Onion Bruschetta

Step 1: Caramelize the Onions

Caramelizing the onions properly is key to the flavor of this bruschetta. Take your time with this step to achieve the perfect golden-brown color.

  1. Heat olive oil and butter: In a large skillet, heat 2 tablespoons of olive oil and butter over medium-low heat.
  2. Add the onions: Add the sliced onions to the skillet, stirring to coat them in the oil and butter. Season with a pinch of salt to help draw out the moisture.
  3. Cook slowly: Reduce the heat to low and cook the onions, stirring occasionally, for about 20-25 minutes. If you like your onions extra sweet, add 1 teaspoon of sugar during the last 5 minutes of cooking.
  4. Set aside: Once the onions are caramelized to a rich golden brown, remove them from the heat and set aside.

Step 2: Grill or Toast the Bread

Grilling or toasting the bread gives it a crisp texture that’s perfect for holding the toppings.

  1. Prepare the bread: Lightly brush both sides of each slice with olive oil to add a hint of flavor and prevent sticking.
  2. Toast or grill: Use a grill pan over medium-high heat or broil in the oven until each side of the bread is golden brown and slightly crisp. This usually takes about 1-2 minutes per side.

Step 3: Assemble the Bruschetta

  1. Layer with caramelized onions: Spoon a generous layer of caramelized onions onto each slice of toasted bread.
  2. Top with blue cheese: Sprinkle crumbled blue cheese over the onions on each slice.
  3. Garnish: Add a few fresh thyme leaves for a touch of brightness and a pop of color.
  4. Optional drizzle: For extra flavor, drizzle a little balsamic glaze over each bruschetta.

Step 4: Serve

  1. Serve immediately: Arrange the bruschetta on a serving platter and serve warm for the best flavor and texture.

Tips for Perfect Blue Cheese and Caramelized Onion Bruschetta

1. Take Your Time with the Onions

Caramelizing onions is a slow process that can’t be rushed. Cooking them on low heat brings out their natural sweetness and gives them a beautiful, rich color. Stir occasionally and be patient for the best results.

2. Choose Quality Blue Cheese

For a well-balanced flavor, opt for a good-quality blue cheese. Creamy Gorgonzola provides a milder flavor, while Roquefort or Stilton will offer a stronger, more intense taste.

3. Adjust the Sweetness

If you prefer a slightly sweeter taste, add sugar to the onions while caramelizing. For a less sweet option, simply omit the sugar.

4. Serve Fresh

Bruschetta is best served fresh. The bread will retain its crispness, and the flavors will be at their peak. If you need to prepare in advance, you can caramelize the onions ahead of time and reheat before assembling.
