Spread olive oil on bottom of pan (and you can add a couple of spoonfuls of sauce too, if desired)
Now it's time to create your first layer: 5 noodles, 1 1/2 - 2 cups bolognese, 1 cup béchamel and 1 - 1 1/2 cups shredded mozzarella plus 1/2 cup grated parmesan
Repeat for second layer
For final layer: skip the béchamel sauce
Cover with foil
Bake at 375 for 30 minutes
Remove foil and continue to bake until browned and bubbly, about 10-15 more minutes
Remove from oven and let stand for at least 15-20 minutes before slicing
