Common Mistakes to Avoid
When making your Spinach Casserole, itβs important to avoid common pitfalls that can affect the final dish.
- Overcooking the spinach: Frozen spinach should be thoroughly drained before mixing. Overcooking can lead to a watery casserole. Make sure to squeeze out excess moisture.
- Skipping the greasing step: Not greasing your casserole dish can result in sticking. Always grease your dish well to ensure easy serving.
- Ignoring ingredient temperature: Using cold ingredients can affect baking time. Let ingredients like cottage cheese and eggs sit at room temperature for about 15 minutes before mixing.
- Not checking for doneness: Relying solely on time may lead to undercooked or overcooked casserole. Check for a set center by gently shaking the dish; it should not be too jiggly before removing.
- Forgetting seasoning adjustments: The flavor of spinach can vary, so taste and adjust seasonings accordingly. Donβt hesitate to add more spices if necessary.
