Start by slicing the top off your garlic, drizzle with some olive oil and season with salt and pepper, then place into your baking dish, sliced side down
Add your ricotta, tomatoes, olive oil and a sprinkle of salt and pepper to the dish
Pop the dish into the oven for 60 minutes
About 5 minutes before the tomato/ricotta mix is finished in the oven, cook your pasta according to packet instructions, drain and set aside - retain about a ladleful of the pasta cooking water, just incase
Remove the tomato and ricotta mix from the oven - add all of the contents to a blender. Don't forget all of the roasting juices
To add the garlic, you'll need to grab the whole bulb and squeeze the edges - all of the cloves should easily pop out into your blender! Discard the skins that you'll be left with
Add a very large handful of fresh basil to the top of the blender
Blend until smooth - add the retained pasta cooking water if you want a thinner sauce
