Creativity - Cooking lesson

This week i decided to cook pasta once again, though slightly different. Last time i made pasta it was simple, with a tomato sauce (with a hint of garlic). This time, my mom told me that there is a different way of making pasta, by baking it. So i decided to try it. I would use a sauce of tomatoes and mozzarella, which would melt while baking, and become very, very nice.
First, i preheated the oven to 200*C; this saves time. While that was heating up, i began boiling a large pot of water. Also simultaneously i took a pan and added some olive oil, an onion that i had already sliced up, two cloves of garlic that i had already finely chopped and a red chilly that i had crumbled up. I let these slowly fry (key word = slowly!) for about 10 minutes or so on a low heat, basically until they were all softened up. Once they were done, i added the tinned plum tomatoes (3x 400g). I then brought it to a boil, turned down the heat and let it simmer for about 20 minutes or so. I made sure to stir it every so often, just to get out the inconsistencies, and make it a nice smooth sauce. While it was simmering, i added some salt to the boiling water, and then put in the pasta (400g). It didn't need to be cooked completely until al dente (as it will still be cooked when baking), but i let it chill for a few minutes in the boiling water, just to make sure it was not completely hard. Once i judged it to be done (i used my mom's help a bit, as i didn't want to get it wrong), i drained the pasta and then mixed it with half of the tomato sauce and a bit of Parmesan cheese. As soon as it looked like it had been mixed together enough, i got a nicely sized baking tray, and sprayed a bit of olive oil (with the handy sprayer) onto the surfaces. I then scooped in all the pasta with the mixed in sauce and cheese. On top of this i put some more tomato sauce, a bit more grated Parmesan and a sliced up mozzarella ball, and repeated this until i had used everything i had (i had enough ingredients for three layers). On the very top i grated some more parmesan, to add a nice crust once baked. I then put this into the preheated oven for around 15 minutes (basically until it was golden and crisp, with a bit of bubbling going on.
