Step-By-Step Cooking Instructions

Preheat the Oven:
- Preheat to 350°F (175°C).
- Grease a 9×9 inch baking dish to prevent sticking.
Prepare the Spinach:
- Steam the spinach until wilted and drain thoroughly.
- Squeeze out any excess water to avoid a watery casserole.
Sauté Onion and Garlic:
- Heat olive oil in a skillet over medium heat.
- Add the chopped onion and garlic, cooking until soft and translucent (about 3-4 minutes).
Mix the Ingredients:
- In a large bowl, combine steamed spinach, ricotta cheese, mozzarella cheese, Parmesan cheese, sautéed onion, garlic, eggs, salt, pepper, and nutmeg (if using).
- Stir well until everything is evenly mixed.
Assemble the Casserole:
- Pour the mixture into the prepared baking dish and spread it out evenly.
Prepare the Topping:
- In a small bowl, mix the breadcrumbs and melted butter.
- Sprinkle this mixture evenly over the top of the casserole for a delicious, golden crust.
Bake the Casserole:
- Place the dish in the preheated oven and bake for 25-30 minutes.
- The top should be golden brown, and a knife inserted in the center should come out clean.
Cool and Serve:
- Allow the casserole to cool for about 5 minutes before serving. This helps it set and makes it easier to cut.

Storage, Freezing & Reheating Instructions

Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freezing: Allow the casserole to cool completely before wrapping tightly in plastic wrap or aluminum foil. Store in a freezer-safe container for up to 3 months.
Reheating: For refrigerated leftovers, reheat in a preheated oven at 350°F (175°C) for 20 minutes, or until heated through. For frozen casserole, thaw overnight in the fridge and then bake at 350°F for 25-30 minutes.
Microwave Option: Individual servings can be reheated in the microwave for 1-2 minutes, but keep in mind the topping may lose some of its crunch.

Common Mistakes to Avoid

Using Watery Spinach: Make sure to squeeze out all excess moisture from the spinach after steaming. Excess water can make the casserole soggy.
Overbaking: Baking too long can dry out the casserole. Keep an eye on it and test with a knife for doneness.
Skipping the Breadcrumb Topping: The buttery breadcrumb topping adds essential texture. Don’t skip this step if you want that satisfying crunch.
Using Low-Quality Cheese: Opt for high-quality ricotta, mozzarella, and Parmesan for the best flavor and creamy consistency.
Improper Storage: Make sure to cool the casserole completely before refrigerating or freezing to prevent condensation from ruining the texture.

Pro Tips

Drain Spinach Thoroughly: After steaming, place the spinach in a clean kitchen towel and squeeze out as much water as possible.
Use Freshly Grated Cheese: Grating cheese straight from the block results in better melting and a creamier texture.
Customize Your Casserole: Add cooked chicken, turkey, or even crumbled sausage to turn this into a more substantial meal.
Add Fresh Herbs: Chopped parsley, thyme, or dill can elevate the flavor of the casserole.
Try Different Cheeses: Cheddar, feta, or gouda can be used for a unique twist on the classic flavor.
