How to Make Spinach and Cheese Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C) and greasing a 9×9-inch casserole dish lightly. This step ensures your casserole doesn’t stick and bakes perfectly. A well-prepped dish always leads to better results and easier cleanup!
Step 2: Sauté the Aromatics
In a skillet set over medium heat, melt the butter. Add the finely chopped onion and sauté for about 3 to 4 minutes until it softens and becomes translucent. Then, stir in the minced garlic and cook for an additional minute. This fragrant base forms the savory backbone of your casserole’s flavor.
Step 3: Combine the Cheesy Mixture
In a large bowl, whisk the eggs until smooth. Stir in ricotta, mozzarella, Parmesan, milk, nutmeg, salt, and pepper, creating a creamy, well-seasoned mixture. These cheeses work in perfect harmony to give this dish its signature richness and gooey texture.
Step 4: Add Spinach and Aromatics
Make sure your spinach is thoroughly drained to avoid a watery mess. Add the well-drained spinach to the egg-cheese mixture along with the sautéed onion and garlic. Stir gently but thoroughly until every bite promises a blend of creamy, cheesy, and green goodness.
Step 5: Assemble and Top
Pour your mixture into the prepared casserole dish, smoothing it out evenly. If you’re using breadcrumbs, toss them with olive oil or melted butter so they crisp nicely, and sprinkle them evenly over the top. This optional topping adds a wonderful texture contrast that’s sure to please.
Step 6: Bake to Perfection
Bake the casserole in your preheated oven for 35 to 40 minutes. You’ll know it’s ready when the center is set and the top has turned a lovely light golden brown. Let it rest for 5 minutes before slicing so it settles and holds together beautifully on the plate.
