Expert Tips:

  • If you have a mandoline, that's the perfect tool to use to ensure consistent slices of zucchini.
  • This recipe is specifically for a 3 inch deep casserole dish. Be sure you have one tall enough!
  • Bake time may very due to oven temperature differentiations and how thick the zucchini slices are.
  • You may need to cover the lasagna to keep from burning the cheese.
