Common Mistakes to Avoid

Not seasoning enough: Under-seasoning the cheese and spinach mixture can lead to bland flavors. Be sure to taste and adjust your seasonings before stuffing.
Using old spinach: Using wilted or older spinach can affect the taste and texture of your dish. Always opt for fresh, vibrant spinach for the best results.
Ignoring cheese quality: Low-quality cheeses can impact flavor. Invest in good-quality ricotta, Parmesan, and mozzarella for a rich and satisfying dish.
