Same steps as previous layers until now! scoop 1/4 of the vegetables in sauce and spread evenly. Sprinkle 1/3 of parmesan cheese and mozzarella cheese evenly.
Cover pan with tin foil and bake for 45 minutes and sides and centre of the pan should be bubbling which is a sign that it is fully baked through. Broil at 450 F for 5 more minutes until cheese is golden.
Cool slightly for 5-10 minutes before cutting into portions or it will be too hot for the portions to hold for plating. Enjoy!
