Ingredients
 
 

  • 1 Tbsp olive oil or butter
  • 1 red or brown onion, peeled and roughly chopped
  • 3 cloves garlic, peeled and minced
  • 4 large eggs
  • 1 1/2 cups whole milk, or milk of choice
  • 1 Tbsp olive oil
  • 1/2 cup all-purpose flour
  • Salt and pepper, to season
  • 2 cups shredded zucchini
  • 1/2 cup shredded cheese, cheddar or any cheese

Method
 

  • Preheat Oven: Preheat the oven to 356°F (180°C). Lightly grease a 7×11-inch rectangle baking dish, set aside.
  • Sauté Onion: Heat olive oil in a medium skillet over medium heat. Add the diced onion and cook, stirring occasionally, until soft and lightly golden.
  • Add Garlic: 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.
  • Add Flour: Add the flour over the egg mixture and whisk for about 20 seconds, just well combined.
  • Stir in Zucchini & Cheese: Add the grated zucchini, shredded cheese, and the cooked onion. Season with salt and pepper, then mix until everything is evenly combined.
  • Bake: Pour the mixture into the greased baking dish and smooth out the top. Bake for 35-40 minutes, or until set in the centre and lightly golden.
  • Cool & Serve: Allow to cool and set slightly for 5-10 minutes before slicing. Serve warm or cold. Enjoy!
