Recipe Information
Ingredients
- 4 tablespoons Unsalted butter
- 2 large Yellow onions
- 1 teaspoon Granulated sugar
- 1 cup All-purpose flour
- 1 teaspoon Baking powder
- 0.5 teaspoon Salt
- 0.25 teaspoon Ground black pepper
- 2 large Eggs
- 0.5 cup Whole milk
- 1 cup Shredded cheddar cheese
- 2 tablespoons Chopped fresh parsley (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish or line it with parchment paper for easy removal.
Melt the butter in a large skillet over medium heat. Peel and thinly slice the onions, then add them to the skillet.
Sprinkle the onions with sugar and cook, stirring occasionally, for about 8-10 minutes until they become soft and golden brown. Remove the skillet from heat and allow the onions to cool slightly.
In a medium mixing bowl, whisk together the flour, baking powder, salt, and black pepper.
In a separate small bowl, beat the eggs and then whisk in the milk.
Pour the wet ingredients into the bowl with the dry ingredients and mix gently until just combined. Do not overmix.
Fold in the caramelized onions and shredded cheddar cheese, mixing until evenly distributed.
Pour the mixture into the prepared baking dish and spread it out evenly.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Let the Onion Squares cool for 5-10 minutes before slicing them into squares. Garnish with fresh parsley, if desired, and serve warm.
