Peel and dice your onion and throw it into your casserole dish along with the garlic puree and the first of the two cans of tinned tomatoes. Cook for 3 minutes on a medium heat or until the onions have started to soften.
Add the mince and cook for a further 10 minutes or until the mince is fully cooked.
Add the second can of tinned tomatoes and turn down to low so that it can cook on a simmer. Once the liquid has reduced add the seasoning, stir well and place 3/4 of the Bolognese into your mixing bowl.
Take your casserole dish off the heat and push down the last ¼ of your Bolognese so that it is layered like the bottom of a lasagne and has no gaps.
Cover it with tiny ½ teaspoon blobs of Philadelphia and then add a layer of lasagne sheets.
Do the same again until you have 4 layers of Bolognese, 4 blob layers of cheese and 4 layers of lasagne sheets.
Then on the top layer of the lasagne sheets, grate the cheese over the lasagne. Season with a little basil and place your casserole dish in the oven and cook for 45 minutes at 180c/360f.
