Preheat oven to 375 °F and grease your lasagna pan.
Spread a spoonful of the meat sauce to cover the bottom of the lasagna pan. This prevents sticking.
Place one layer of lasagna noodles to cover the bottom of the pan.
Spread ⅓ of the ricotta cheese mixture over the top of the noddles.
Sprinkle a layer of fresh spinach leaves.
Sprinkle a thin layer of mozzarella (about ¼ cup) and 2 tbsp of shredded parmesan.
Top with 1 -1 ½ cups of meat sauce and spread to an even layer.
Repeat the noodle to meat sauce layers 2 more times.
Place the 4th layer of noodles then top with remaining meat sauce. Sprinkle generously with remaining mozzarella and additional parmesan cheese.
Cover pan with aluminum foil and then transfer to oven to bake for 45 minutes or until bubbling.
Remove foil cover and allow cheese to finish melting and turn golden brown then remove from oven. Serve after allowing to cool for a 5-10 minutes for best results.
