Instructions

Preheat Oven: Preheat the oven to 375°F (10°C). Line a 7×11-inch rectangle baking dish with parchment paper, set aside.
Sauté Onion & Garlic: Heat olive oil in a small saucepan over medium-high heat. Add the onion and cook, stirring occasionally, until golden, about 5 minutes. Add the minced garlic and cook for 1 minute until fragrant. Remove from the heat and set it aside to let it cool slightly while you prepare the filling.
Whisk Wet Ingredients: In a large mixing bowl, whisk together the eggs, milk, and olive oil until well combined.
Add Flour: Add the flour over the egg mixture and whisk for about 20 seconds, until well combined.
Stir in Zucchini & Cheese: Add the shredded zucchini, shredded cheese, and the cooked onion and garlic mixture. Season with salt and pepper, then mix again to combine.
Bake: Pour the mixture into the prepared baking dish and smooth out the top. Bake for 35-40 minutes, or until set in the center and lightly golden all over.
Cool & Serve: Allow to cool and set slightly for 5 minutes before slicing. Serve warm or cold. Enjoy!
