Instructions for Making Baked Savory Oat Slice

Making this dish is a relaxed, enjoyable process that doesn’t need much prep. Here’s how to bring it all together:

Preheat Your Equipment:
Preheat your oven to 180°C (350°F). Lightly grease or line an 8×8 inch baking dish with parchment paper.
Combine Ingredients:
In a large mixing bowl, whisk the eggs and milk together. Add the grated zucchini, carrot, cheese, herbs, salt, pepper, and baking powder. Stir in the oats last and mix until everything is well combined.

Assemble the Dish:
Press the mixture gently to ensure it’s compact. Sprinkle a little extra cheese or herbs on top if desired.
Cook to Perfection:
Bake for 35–40 minutes, or until the top is golden and the center is set. A toothpick inserted in the middle should come out clean.
Finishing Touches:
