Step 1: Caramelize the Onions
In a skillet, melt butter over medium heat.
Add the chopped onions and sauté until they are soft and golden brown, about 10-15 minutes. Stir occasionally to avoid burning. Set aside to cool.Step 2: Prepare the Batter
Preheat the oven to 350°F (175°C).
In a mixing bowl, whisk together the flour, baking powder, salt, and sugar.
In another bowl, beat the egg and add the milk, mixing until well combined.
Add the cooled caramelized onions to the wet mixture and stir to combine.
Gradually add the wet ingredients to the dry ingredients, mixing until smooth.Step 3: Bake the Squares
Pour the batter into a greased 8×8-inch baking dish.
Spread the mixture evenly.
Bake for 30-35 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.Step 4: Cool and Serve
Allow the onion squares to cool for a few minutes before cutting them into squares.
Garnish with fresh parsley, if desired, and serve warm.
Notes
- Cheese Option: Adding grated cheddar cheese to the batter will give the squares a rich, cheesy flavor. You can also experiment with different types of cheese like Parmesan or Gruyère for a unique twist.
- Storage: Leftover onion squares can be stored in an airtight container at room temperature for up to 3 days. You can reheat them in the oven to maintain their flaky texture.
- Variation: For a more savory version, you can sprinkle some herbs like thyme or rosemary into the batter for added flavor.
