📝 Instructions

10 steps
1

Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish or line it with parchment paper for easy removal.

2

Melt the butter in a large skillet over medium heat. Peel and thinly slice the onions, then add them to the skillet.

3

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.

4

In a medium mixing bowl, whisk together the flour, baking powder, salt, and black pepper.

5

In a separate small bowl, beat the eggs and then whisk in the milk.

6

Pour the wet ingredients into the bowl with the dry ingredients and mix gently until just combined. Do not overmix.

7

Fold in the caramelized onions and shredded cheddar cheese, mixing until evenly distributed.

8

Pour the mixture into the prepared baking dish and spread it out evenly.

9

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.

10

Let the Onion Squares cool for 5-10 minutes before slicing them into squares. Garnish with fresh parsley, if desired, and serve warm.
