Ingredients
To prepare this flavourful casserole, gather the following ingredients. Each item has been listed with its approximate calorie count per serving to give you a clear idea of the dish’s nutritional value.
Ingredient | Quantity | Calories (approx) |
---|---|---|
Cooked rice | 2 cups | 410 |
Fresh spinach | 4 cups | 28 |
Onion, finely chopped | 1 medium | 44 |
Garlic, minced | 2 cloves | 8 |
Olive oil | 2 tbsp | 240 |
Milk | 1 cup | 100 |
Shredded cheddar cheese | 1 cup | 400 |
Parmesan cheese | ¼ cup | 110 |
Egg | 1 large | 70 |
Salt and pepper | To taste | Negligible |
How to Prepare
Start by preheating your oven and lightly greasing a casserole dish. In a skillet, heat olive oil and sauté the onion until it becomes soft and translucent, then add the garlic and cook until fragrant. Stir in the spinach and allow it to wilt down completely before removing the mixture from heat. In a large mixing bowl, combine the cooked rice, sautéed spinach mixture, milk, egg, cheddar, and half of the Parmesan cheese. Season generously with salt and pepper to enhance the flavors.
Once the ingredients are well combined, transfer the mixture into the prepared casserole dish and spread it evenly. Sprinkle the remaining Parmesan cheese over the top to create a golden crust as it bakes. Place the dish in the oven and bake until the casserole is set and the top has turned golden brown. Let it rest for a few minutes before serving to allow the flavors to settle and the texture to firm up.
Pro Tips
For the best flavor, use freshly cooked rice rather than leftover rice, as it gives the casserole a softer texture. If you prefer a richer dish, substitute half of the milk with cream for a more indulgent flavor. Adding a pinch of nutmeg or red pepper flakes can elevate the taste with subtle warmth. Always make sure the spinach is well drained to prevent excess liquid from making the casserole soggy. To save time, you can also use frozen spinach, but thaw it completely and squeeze out the moisture before adding it to the mixture.
Perfect Pairings and Toppings
This spinach rice casserole pairs beautifully with roasted chicken, grilled fish, or baked salmon for a well balanced meal. For a vegetarian spread, serve it with a fresh garden salad or roasted vegetables. Adding toppings like breadcrumbs, extra cheese, or even a drizzle of hot sauce can bring out new layers of flavor. A side of crusty bread also makes a great companion, allowing you to soak up the creamy goodness of the casserole.
