I have not tried these yet, putting here for safe-keeping. Looks like they would be a terrific addition to the holiday buffet table or to serve as an hors d'oeuvre before dinner or at a cocktail party. If I don't want to make the crust, I would use this topping on bruschetta. I also might try chopped fresh rosemary instead of the thyme.

Time 1h20m

Yield 6 serving(s)

Number Of Ingredients 15

Ingredients

2 cups plain flour
2 teaspoons baking powder
1/2 teaspoon kosher salt
3/4 cup whole milk
1/4 cup olive oil
2 tablespoons unsalted butter, melted
2 tablespoons unsalted butter
2 tablespoons olive oil
3 large red onions, thinly sliced
1 tablespoon finely chopped fresh thyme
1 teaspoon sugar
kosher salt
fresh ground black pepper
1/2 cup crumbled blue cheese
1/2 cup crumbled fresh goat cheese

Steps:

Preheat the oven to 425°F.
To make the crust:.
In a medium bowl, stir together the flour, baking powder, and salt. Make a well in the center of the mixture.
In a measuring cup, whisk together the milk, olive oil, and melted butter. Slowly pour the milk mixture into the well, stirring until just blended and the mixture comes together into a rough mass.
Turn out the dough onto a lightly floured work surface and roll out into a 10-by-13-inch rectangle.
Transfer the dough to a baking sheet/tray. Pierce the dough all over with a fork.
To make the topping:
In a large skillet over medium heat, melt the butter with the olive oil. Add the onions and cook, stirring frequently, until softened and lightly browned, about 10 minutes.
Add the thyme, sugar, and salt and pepper to taste, reduce the heat to low, and cook, stirring frequently, until the onions are soft and caramelized, about 20 minutes.
Spread the onion mixture evenly over the dough.
Sprinkle with the cheeses, cut into squares with a pizza wheel or a sharp knife, and bake until the crust is golden and the cheese is bubbling, about 20 minutes.
Transfer to a wire rack and let cool a bit on the pan. Serve warm or at room temperature.

Tips:

For a richer flavor, use a combination of yellow and white onions for caramelizing.
Cook the onions slowly over low heat to achieve a deep golden color and sweet flavor.
If the onions start to brown too quickly, reduce the heat or add a splash of water.
Use a sharp knife to thinly slice the onions for even caramelization.
Grate the cheese finely for a smooth and creamy filling.
Use a baking dish that is at least 8x8 inches to ensure the cheese squares are evenly baked.
For a crispy crust, brush the tops of the cheese squares with melted butter before baking.
Let the cheese squares cool slightly before cutting them into squares to prevent them from falling apart.

Conclusion:

These caramelized onion cheese squares are a delightful appetizer or snack that can be enjoyed by people of all ages. They are easy to make and can be tailored to your own taste preferences. With their sweet and savory flavor, crispy crust, and gooey cheese filling, these cheese squares are sure to be a hit at your next party or gathering.
