Why I Love This Recipe

Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

Step-by-Step Instructions

1. 1

   Preheat your oven to 350°F (175°C). This ensures the casserole cooks evenly and the cheese melts beautifully.

   ~2 min

   Tip: Make sure your oven is fully preheated for optimal results.
2. 2

   Thaw the frozen spinach completely. Once thawed, squeeze out as much excess water as possible. This step is crucial to prevent a watery casserole.

   ~5 min

   Tip: Wrap the spinach in a clean kitchen towel and twist to remove the water effectively.
3. 3

   In a skillet, melt a tablespoon of butter or olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Cooking the onion first mellows its flavor and adds depth to the casserole.

   ~7 min

   Tip: Don't overcrowd the skillet; cook the onions in batches if necessary.
4. 4

   Add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter.

   ~1 min

   Tip: Keep the heat relatively low to prevent burning the garlic.
5. 5

   In a large bowl, combine the softened cream cheese, sour cream, and mayonnaise. Mix until smooth and creamy, ensuring there are no lumps of cream cheese.

   ~3 min

   Tip: Using an electric mixer makes this step easier, but it can also be done by hand.
6. 6

   Add the squeezed spinach, sautéed onion and garlic mixture, salt, and pepper to the bowl with the cream cheese mixture. Stir well to combine all ingredients thoroughly.

   ~2 min

   Tip: Ensure the spinach is evenly distributed throughout the mixture.
7. 7

   Stir in 1 1/2 cups of the shredded cheddar cheese and the grated Parmesan cheese. Reserve the remaining 1/2 cup of cheddar cheese for topping.

   ~1 min

   Tip: Mixing the cheese into the casserole ensures a cheesy flavor throughout.
8. 8

   Pour the spinach mixture into a greased 8x8 inch baking dish. Ensure it's evenly distributed.

   ~1 min

   Tip: You can also use a slightly larger baking dish, but the casserole will be thinner.
9. 9

   Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole. This creates a delicious cheesy crust.

   ~1 min

   Tip: For an extra golden crust, broil for the last minute or two of baking, watching carefully to prevent burning.
10. 10

    Bake in the preheated oven for 30-35 minutes, or until the casserole is heated through, bubbly, and the cheese is melted and lightly golden brown. The edges should be slightly browned and the center set.

    ~35 min

    Tip: Insert a knife into the center; it should come out hot.
11. 11

    Let the casserole cool for a few minutes before serving. This allows it to set slightly and makes it easier to cut and serve.

    ~5 min

    Tip: Garnish with a sprinkle of fresh parsley, if desired, for a pop of color.
12. 12

    Serve warm and enjoy! This casserole is a perfect side dish for almost any meal, but also works well on its own.
