Ingredients

This recipe makes 4-6 servings.

• For the Vegetables:
• 3 medium zucchini (about 1.5 lbs), trimmed and thinly sliced into rounds
• 1 teaspoon salt (for zucchini)
• 1 tablespoon olive oil
• 1 small yellow onion, finely chopped
• 2 cloves garlic, minced
• 5 oz fresh spinach, roughly chopped
• For the Creamy Base:
• 3 large eggs
• 1 cup milk (any kind, whole or 2% works best)
• 2 tablespoons all-purpose flour
• 1/2 teaspoon black pepper
• 1/4 teaspoon dried dill or oregano (optional)
• For the Cheese:
• 4 oz feta cheese, crumbled
• 1/4 cup shredded mozzarella or Parmesan cheese (optional, for topping)

Step-by-Step Instructions

1. Step 1: Prepare the Zucchini

   Start by slicing your zucchini into thin rounds, about 1/8 to 1/4 inch thick. Lay them out on paper towels, sprinkle with 1 teaspoon of salt, and let them sit for 15-20 minutes. This step draws out excess moisture, preventing your casserole from becoming watery.

   Small tip: Don’t skip salting the zucchini! It’s a key step for a perfectly textured casserole. While the zucchini is resting, you can gather your other ingredients.

2. Step 2: Preheat Oven and Prep Baking Dish

   Preheat your oven to 375°F (190°C). Lightly grease a 9×9 inch baking dish or a similar-sized oven-safe dish with olive oil or cooking spray. This will help prevent sticking and ensure easy cleanup.

3. Step 3: Sauté Aromatics

   Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3-4 minutes until softened and translucent. Stir in the minced garlic and cook for another minute until fragrant.

4. Step 4: Wilt the Spinach

   Add the chopped fresh spinach to the skillet with the onions and garlic. Cook, stirring occasionally, for 2-3 minutes until the spinach has fully wilted and most of its liquid has evaporated. Remove from heat and set aside.

   Small tip: If your spinach releases a lot of water, gently squeeze out any excess before adding it to the casserole mixture.

5. Step 5: Pat Dry Zucchini and Combine

   While the spinach cools slightly, use clean paper towels to firmly pat dry the salted zucchini slices. This removes both the salt and the extracted moisture. In a large bowl, combine the patted-dry zucchini, the wilted spinach mixture, and the crumbled feta cheese. Gently toss everything together.

6. Step 6: Prepare the Creamy Custard

   In a separate medium bowl, whisk together the eggs, milk, all-purpose flour, black pepper, and dried dill or oregano (if using). Whisk until the mixture is smooth and the flour is fully incorporated. This creates the delicious, creamy base for your casserole.

7. Step 7: Assemble the Casserole

   Pour the egg mixture over the zucchini, spinach, and feta in the large bowl. Stir gently to ensure all the vegetables and cheese are coated. Transfer the entire mixture into your prepared baking dish, spreading it evenly.

8. Step 8: Bake to Golden Perfection

   If desired, sprinkle the top with the optional shredded mozzarella or Parmesan cheese for an extra golden crust. Bake in the preheated oven for 30-35 minutes, or until the casserole is set, golden brown on top, and bubbling around the edges. A knife inserted into the center should come out clean.

9. Step 9: Rest and Serve

   Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving. This allows the casserole to set further, making it easier to cut into neat portions. Enjoy your delicious homemade casserole!

Tips & Variations

• Gluten-Free Option: Easily make this casserole gluten-free by swapping the all-purpose flour for 2 tablespoons of cornstarch or your favorite gluten-free all-purpose flour blend. The texture will be just as wonderful!
• Vegan/Dairy-Free Option: For a vegan version, omit the feta and use a plant-based crumbled “feta” alternative. Replace the eggs with a flax egg (1 tbsp ground flaxseed + 3 tbsp water per egg, let sit for 5 mins) or a plant-based egg substitute. Use unsweetened plant-based milk (like almond or soy milk) instead of dairy milk.
• Add More Vegetables or Protein: Feel free to customize! Sautéed mushrooms, diced bell peppers, or cherry tomatoes halved would be lovely additions. For extra protein, stir in cooked, shredded chicken, canned chickpeas, or even some crumbled cooked sausage.
• Spicy Kick: If you love a little heat, add a pinch or two of red pepper flakes to the egg mixture. For more intense spice, finely dice a small jalapeño and sauté it with the onions and garlic.
• Herb & Cheese Swaps: Experiment with different herbs like fresh parsley, basil, or thyme. Instead of feta, try goat cheese for a creamier, tangier flavor, or a mix of Parmesan and cheddar for a different cheesy profile.
