Slice vegetables (the 8-ball zucchini is excellent for this recipe, but regular zucchini “coins” or lengthwise cuts are also good!)
Season and brown ground beef as desired.
Drain beef and set aside.
Layer the vegetables as you would lasagna...
... with layers of beef and ricotta cheese.
Layer more vegetables.
Continue layering for a deep dish.
Top with Parmesan cheese.
Bake at 350 for approximately 50 minutes until vegetables are cooked to your satisfaction.
