- Experiment with cheese: Try adding different cheeses like mozzarella or ricotta for varied flavors.
- Add spices: Enhance the dish by incorporating herbs like dill or oregano for an aromatic touch.
- Check doneness: The casserole should be set in the center but still slightly jiggly when you take it out of the oven.

Common Mistakes to Avoid
When preparing your Spinach Casserole, some common mistakes can affect the final outcome. Here are a few to keep in mind:
- Not draining spinach properly: Failing to drain the thawed spinach can lead to a watery casserole. Make sure to squeeze out as much liquid as possible before adding it to the mix.
- Skipping ingredient room temperature: Using cold ingredients can affect how well they blend together. Let your cottage cheese and eggs sit out for a bit before mixing.
- Overbaking the casserole: Cooking it too long can result in a dry texture. Keep an eye on it during the last few minutes of baking.
- Ignoring seasoning adjustments: Each brand of feta and cottage cheese varies in salt content. Taste your mixture before baking and adjust the seasoning as needed.
- Using a small dish: Choosing a dish that is too small can cause overflow during baking. Opt for a 9-inch square casserole dish for best results.
