In a heavy bottomed sauce pan on medium heat add olive oil. Reduce heat and add minced garlic and cook until soft.
Add crushed tomatoes and bring to a boil. Tear basil leaves and add to sauce, stir in and cook for about 1 minute or 2 minutes longer, remove form heat and season with salt to taste. Cover and place in refrigerator to cool.
Assembly
Preheat oven to 400°F.
On a clean counter top, lay out a long layer of parchment paper. Lay out one of your pasta sheetson top.
Note: Ideally all your sheets are the same length so they overlap nicely.
Spread a thin layer of béchamel evenly across the pasta sheet
Sprinkle Parmesan and mozzarella over the béchamel. Place another sheet of pasta on top. Spread a layer of bolognese evenly across the second pasta sheet. Add a sufficient amount but not too too much or else it will be hard to roll.
Roll the layered pasta into a log using parchment paper to help you. Wrap in parchment paper and place in fridge and let cool.
Repeat with other 2 pasta sheets to make another log.
When lasagna logs are cool, prep dish.
Ladle the tomato sauce into a casserole to cover the entire bottom of the dish, slice your logs using a sharp knife. I get about 6 pinwheels per log. You can cut them thicker and get fewer pinwheels per log.
Lay lasagna pinwheels into the casserole dish, with the cut sides facing up, until the dish is full.
In a small bowl add your ricotta and Boursin cheese, season with salt and pepper to taste and add dollops between pinwheels.
Cook in oven for at least 15 minutes or until pasta edges are golden brown. I like mine after about 25 minutes.
Top with chopped parsley and serve.
You can keep your second log refrigerated for up to 3 days until you are ready to slice and bake. Make sure to reserve your shredded cheese, ricotta-Boursin mixture and tomato sauce for assembly of your second lasagna.
