- 1/2 cup milk (dairy or unsweetened plant-based) Helps blend the filling and keeps it moist.
🧂 Seasonings & Pantry
- 1/4 cup olive oil For sautéing and added richness.
- 1/4 cup chopped fresh parsley Brightens up the flavor; you can substitute with basil or dill.

Step-by-Step Instructions
✅ Step 1: Prep the Zucchini
Grate the zucchini using a box grater or food processor. Place in a colander with a pinch of salt and let sit for 10 minutes. This step is crucial—it helps draw out water. Afterward, squeeze out as much liquid as possible using a clean towel or your hands.
✅ Step 2: Sauté the Aromatics
In a skillet, heat olive oil over medium heat. Add the diced onion and cook for 3–4 minutes until soft and translucent. Add garlic and cook another 30 seconds. Stir in the chopped spinach and cook for 2–3 minutes until wilted. Remove from heat.
✅ Step 3: Mix the Casserole Filling
In a large mixing bowl, whisk together the eggs, milk, oregano, parsley, salt, and pepper. Stir in the feta and Parmesan cheese. Add the squeezed zucchini and sautéed spinach mixture. If using breadcrumbs or almond flour, fold them in at this stage.
✅ Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or equivalent.
Pour the mixture into the dish and spread evenly. Sprinkle mozzarella on top if you want a cheesy crust.
✅ Step 5: Bake It
Bake for 35–40 minutes or until the top is golden brown and the center is firm. A toothpick inserted into the middle should come out clean. Let it rest for 10 minutes before slicing.
