Tips for Success

• Fresh spinach option: You can use fresh spinach instead of frozen. Simply blanch the spinach in boiling water, drain, and chop before using.
• Cheese variations: Experiment with different cheeses such as Gruyère, Fontina, or a smoked cheddar for added depth of flavor.
• Make it heartier: Add cooked bacon bits, diced ham, or shredded chicken to the mixture for a protein boost.

Serving Suggestions

This cheesy spinach casserole pairs beautifully with roasted chicken, grilled fish, or a juicy steak. It can also be served as a vegetarian main course with crusty bread or a side salad.

Storage and Reheating

• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheating: Reheat in the oven at 350°F (175°C) for 10-15 minutes, or microwave individual portions until warm.
