💡 Tips for Success

• Salt the eggplant slices and let them sit for 20–30 minutes, then pat dry to reduce bitterness.
• Roast the vegetables before layering to prevent excess moisture.
• Use freshly grated mozzarella for the best melt.
• Let the casserole rest before serving for cleaner slices.
• Homemade marinara adds extra depth of flavor.
