🧾 Ingredients
Here’s what you’ll need to prepare this delicious casserole:
- 8 large eggs
- 1 cup milk (whole milk preferred for creaminess)
- 2 cups fresh spinach (roughly chopped)
- 1 cup shredded cheddar cheese
- ½ cup mozzarella cheese (optional but recommended)
- 1 small onion (finely chopped)
- 2 cloves garlic (minced)
- 1 tablespoon olive oil
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon paprika (optional for added flavor)
- ½ teaspoon dried oregano or thyme
- 4 slices of bread (cubed) OR 1 cup cooked potatoes (optional base)
- Butter or cooking spray (for greasing the dish)
🍳 Step-by-Step Instructions
1. Preheat the Oven
Start by preheating your oven to 180°C (350°F). Grease a medium-sized baking dish with butter or cooking spray to prevent sticking.
2. Prepare the Vegetables
Heat olive oil in a pan over medium heat. Add the chopped onion and sauté for about 2–3 minutes until it becomes soft and translucent. Then add minced garlic and cook for another minute until fragrant.
Add the chopped spinach to the pan and cook until it wilts down. This usually takes 2–3 minutes. Remove from heat and set aside to cool slightly.
3. Prepare the Egg Mixture
In a large mixing bowl, crack the eggs and whisk them thoroughly. Add milk, salt, pepper, paprika, and dried herbs. Mix well until everything is evenly combined.
4. Assemble the Casserole
Spread the bread cubes or cooked potatoes evenly at the bottom of the greased baking dish. This forms the base layer and helps absorb the egg mixture.
Next, spread the cooked spinach, onion, and garlic mixture over the base. Sprinkle the shredded cheddar and mozzarella cheese evenly on top.
Finally, pour the egg mixture over everything, making sure it spreads evenly across the dish.
5. Bake
Place the dish in the preheated oven and bake for 30–40 minutes, or until the casserole is set in the center and the top is lightly golden. You can check doneness by inserting a knife or toothpick—it should come out clean.
6. Cool and Serve
Let the casserole rest for about 5–10 minutes before slicing. This helps it firm up and makes serving easier.
