How to Make Spinach Casserole
Step 1: Preheat the Oven
Preheat your oven to 350 degrees F. This ensures that the casserole cooks evenly.

After mixing everything together well, transfer the mixture into the greased casserole dish.
Step 5: Bake
Bake uncovered for about 40-45 minutes or until the center is nearly set. Keep an eye on it towards the end; you want a slightly firm texture.
Step 6: Cool and Serve
Let cool for 5-10 minutes before cutting into squares. Serve warm and enjoy your delicious Spinach Casserole!

Common Mistakes to Avoid
Avoiding common mistakes can elevate your Spinach Casserole from good to great. Here are some pitfalls to watch out for:
- Using unfrozen spinach: Fresh spinach contains a lot of moisture, which can make the casserole soggy. Always use frozen spinach that has been thoroughly drained.
- Not beating the eggs well: Eggs provide structure and binding. If they aren’t beaten well, they might not incorporate fully into the mixture. Whisk them until fully combined and slightly frothy.
- Skipping the seasoning: A bland casserole can ruin the dish. Make sure to season with salt, pepper, and spices like nutmeg to enhance flavors.
- Overbaking: Baking too long can lead to a dry casserole. Keep an eye on it, and remove it when the center is almost set but still slightly jiggly.
- Incorrect serving size: Cutting too large of portions can make it difficult to serve. Aim for smaller servings, especially if serving as a side dish.
