Notes

You can prepare the meat sauce a day ahead for deeper flavor.
Allow lasagna to rest before cutting to maintain clean slices.
Substitute ground beef with a mix of beef and pork for richer taste.
Cover with foil if the top browns too quickly while baking.
Leftovers taste even better the next day and store well in the refrigerator.
