Ingredients
- 4 medium zucchinis, thinly sliced

- 1 cup crumbled feta cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup Greek yogurt
- 2 cloves garlic, minced
- 1/2 teaspoon dried oregano
- 1/2 teaspoon dried basil
- Salt and pepper to taste
- 1 tablespoon olive oil
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil or cooking spray.
2. Prepare the Zucchini
Thinly slice the zucchinis into rounds. Place them in a colander and sprinkle with salt. Let them sit for 10 minutes to draw out excess moisture. Pat dry with a paper towel.
3. Sauté the Spinach
In a skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for 1 minute until fragrant. Add the chopped spinach and cook until wilted, about 2-3 minutes. Remove from heat and set aside.
4. Mix the Ingredients
In a large bowl, combine the sliced zucchini, sautéed spinach, crumbled feta cheese, grated Parmesan cheese, Greek yogurt, dried oregano, dried basil, salt, and pepper. Mix well to ensure all ingredients are evenly distributed.
5. Assemble the Casserole
Transfer the mixture to the prepared baking dish, spreading it out evenly. Press down gently to compact the layers.
6. Bake
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbly.
7. Serve
Let the casserole cool for a few minutes before slicing and serving. Enjoy it as a main dish or a side with your favorite protein.
