Notes
Salt and rest zucchini slices to reduce moisture and avoid watery gratin.
Substitute mascarpone with cream cheese or ricotta if preferred.
Add fresh herbs like thyme or basil for extra flavor.
Use Gruyere or fontina cheese for richer taste.
Broil for 2-3 minutes at the end for a crispier top.
Freeze leftovers for up to 1 month; thaw and reheat thoroughly.
