Ingredients

Scale

Cheese and Dairy

1½ cups shredded mozzarella cheese
½ cup grated Parmesan cheese
3 large eggs

Vegetables

2 medium yellow onions, thinly sliced
2 garlic cloves, minced
2 tablespoons chopped fresh parsley

Dry Ingredients

½ cup all-purpose flour
1 teaspoon baking powder
1 teaspoon onion powder
1 teaspoon garlic powder
1 teaspoon dried thyme
½ teaspoon dried oregano
1 teaspoon salt
½ teaspoon black pepper

Fats and Oils

2 tablespoons olive oil
2 tablespoons unsalted butter

Others

Cooking spray or butter for greasing the baking dish

Instructions

Prepare the Oven: Preheat your oven to 375°F (190°C). Grease a 9×9-inch baking dish with butter or cooking spray to prevent sticking and ensure easy removal of the casserole.
Caramelize the Onions: In a large skillet over medium heat, heat olive oil and butter. Add the thinly sliced onions and cook slowly for 15–20 minutes, stirring occasionally until the onions become soft, golden, and naturally sweet. In the last minute, add the minced garlic and cook until fragrant. Remove from heat and allow to cool slightly.
Mix the Dry Ingredients: In a medium bowl, whisk together flour, baking powder, onion powder, garlic powder, dried thyme, dried oregano, salt, and black pepper until evenly combined.
Prepare the Cheese Mixture: In a large mixing bowl, whisk the eggs until smooth. Add the cottage cheese, shredded mozzarella, and grated Parmesan, stirring to combine. Fold in the cooled caramelized onions and chopped fresh parsley gently to incorporate all flavors evenly.
Combine Everything: Gradually add the dry ingredients to the cheese and onion mixture, stirring gently just until no dry flour remains. Avoid overmixing to maintain a light and tender texture in the bake.
Fill the Baking Dish: Spread the mixture evenly into the prepared baking dish, smoothing the top with a spatula. Optionally, sprinkle additional mozzarella and Parmesan on top for an extra golden and crispy crust.
Bake: Place the baking dish in the oven and bake for 40–45 minutes. The top will turn golden brown and become lightly crisp around the edges. The center should be set and should not jiggle when gently shaken.
Cool Slightly: Remove the casserole from the oven and let it rest for about 10 minutes. This resting period allows the bake to firm up, making it easier to slice cleanly.
Garnish and Serve: Sprinkle with fresh parsley or chopped chives before serving. Enjoy warm for best flavor and texture.

Notes

Cook onions slowly to develop maximum sweetness and depth of flavor.
If using very wet cottage cheese, drain any excess liquid to prevent a watery casserole.
Allow onions to cool before adding to eggs to avoid curdling.
Freshly grate cheese for best melting texture.
Let the bake rest before slicing to improve slice integrity.
Don’t overbake to avoid dryness; the casserole will continue to set while cooling.
Feel free to add extra fresh herbs for enhanced flavor.
Use a ceramic or glass baking dish to promote even cooking and a better crust.
Taste the onion mixture and adjust seasonings before assembling if needed.
Garnish just before serving for the freshest look and flavor.
