Slice eggplant and salt both sides generously 30 minutes before grilling to draw out excess moisture, preventing sogginess and ensuring a firmer, more flavorful texture that grills beautifully.

Brush oil directly onto hot grill grates before placing eggplant to create a non-stick surface and achieve those coveted caramelized char marks that add smoky depth to your stacks.

Layer mozzarella and marinara on the grilled eggplant while still hot so the cheese slightly melts and bonds the stack together, creating better texture cohesion and flavor integration.

Add fresh basil leaves after the stack cools slightly rather than during grilling to preserve their vibrant color, aromatic oils, and peppery flavor that fresh herbs lose under direct heat.

After the 30-minute salt rest, pat eggplant slices completely dry with paper towels to remove excess liquid and prevent steaming on the grill, ensuring crispy edges and tender interiors.
