Step-by-Step Cooking Instructions

Start by preheating your oven to 375 degrees Fahrenheit. Lightly grease a square baking dish with a bit of olive oil or cooking spray. This helps the casserole bake evenly and prevents sticking.

In a skillet over medium heat, warm the olive oil. Add the chopped onion and cook until it becomes soft and translucent. Stir in the minced garlic and cook for another minute. You want the garlic to release its aroma without browning too much.

Next, add the spinach to the skillet. If you are using fresh spinach, cook until it wilts down completely. For frozen spinach, make sure it’s thawed and squeeze out any extra water before adding it. Let the spinach cook until all the moisture has evaporated. This prevents the casserole from becoming watery later.

In a large mixing bowl, combine the cooked rice, spinach mixture, eggs, milk, shredded cheddar, salt, and pepper. If you’re using parmesan cheese, add it to the mix for an extra layer of flavor. Stir everything until well combined. The mixture should be creamy but not too wet.

Pour the entire mixture into the prepared baking dish. Spread it out evenly with a spatula. Bake in the oven for about 30 to 35 minutes or until the top is golden and slightly crisp. You’ll know it’s ready when the edges start to pull away from the dish and the center is set.

Let it rest for about five minutes before serving. This gives it time to firm up and makes it easier to slice.

Tips for Customizing the Recipe

One of the best parts of this recipe is how easy it is to customize. You can tweak the ingredients to fit your diet, use up leftovers, or simply add what you love.

If you want to add protein, cooked shredded chicken or turkey works great. Canned tuna or chickpeas are good choices too. For a vegetarian protein boost, try stirring in some cooked lentils or tofu.

Feel free to add extra vegetables. Chopped mushrooms, bell peppers, or even grated carrots fit in well with the flavor. Just make sure to cook or sauté them first to remove moisture.

To make it dairy-free, use plant-based milk and vegan cheese. The texture will still be creamy and satisfying.

If you like spice, a pinch of cayenne pepper or some red pepper flakes will add a gentle kick. You could also swap in pepper jack cheese for a spicier version.

Don’t be afraid to get creative. This dish is very forgiving and adapts well to different tastes.
