How to make zucchini, feta, and egg casserole
- Preheat the oven to 375 °F, 190 °C.
- Place the shredded zucchini in a colander and sprinkle 1-2 teaspoons of salt. Toss and set aside in the sink or over a bowl to drain for 15 minutes.
- Sauté the scallions in the olive oil over medium heat until soft—about 3 minutes.
- Then, add the garlic and warm through until fragrant.
- Squeeze the liquid out of the zucchini and add it to the scallions and garlic.
- Cook over medium-high heat for 8-10 minutes. The zucchini will release more juices and will dry in the pan.
- Transfer to a large bowl and allow to cool or cool in the pan.
- Once cooled, add the herbs and toss them together.
- Taste and adjust the seasoning if needed.
- Next, beat the eggs and cream and season with salt and black pepper.
- Add the zucchini to the eggs and stir together.
- Crumble the feta cheese into the mix and stir to combine.
- Transfer the mixture to a greased 9 x 13-inch (23 by 33 cm) baking pan.
- Sprinkle the shredded mozzarella cheese on top and bake on the center rack for about 25 minutes.
- Cool for about 15 minutes, cut into squares, and serve.

Freezer Instructions
Bake the casserole and allow it to cool completely. Cut it into portions and transfer it to a freezer-safe bag or container. You can keep it fresh in the freezer for up to 2 months. Thaw and toast in the oven to serve.

Serving
This casserole is best when served warm or at room temperature. Add a bowl of tzatziki on the side so everyone can dollop as much as they’d like on top. You can serve it with a side salad, cauliflower rice, or even put it on a sandwich if you don’t care about keeping it low-carb. Store any leftovers in an airtight container in the refrigerator for 5-6 days. Doesn’t that sound like delicious zucchini, feta, and egg casserole every day of the week? Kali Orexi!
