Preheat your oven to 375°F (190°C).
Bring a large pot of salted water to a boil with olive oil.
Cook the lasagna noodles per package instructions, then drain and lay flat on a clean towel.
Butter the bottom of a 9x13 inch baking dish generously to prevent sticking.
Spread a thin layer of bechamel sauce on the bottom.
Add the first layer of noodles on top of the bechamel.
Then, add a layer of bolognese sauce followed by a sprinkle of grated Parmesan.
Repeat the layers: bechamel, noodles, bolognese, and Parmesan until you have three to four layers.
Top with the remaining bechamel and Parmesan.
Place small butter dots on the top for added richness.
Bake in the preheated oven for about 45 minutes until golden and bubbly.
