[Entree] Gordon Ramsey Cookalong Lasagna, Take 2

I've been following Gordon Ramsey's "Cookalong Live", albeit a bit delayed. However, I have to share and show off my attempt at his Lasagna Al Forno. The first time I did full mise en place, and it took about 75 minutes to put together. The second time it took about 45 minutes, and is utterly fantastic. Only takes a few ingredients that you might not have, nothing really too special (except for the pre-cooked lasagna sheets), and comes together VERY easily.

Highly recommended. There's even videos on how to make it.
Two hints
1) Tomato paste, not puree - the brits apparently name things differently.
2) Mince - ground beef, about 2/3 - 3/4 of a pound. I use 85/15 ground beef and it comes out wonderfully.

And since they can't be arsed to keep the recipe in one place (or even searchable on their own site...)

METHOD

How to make Gordon's classic lasagne al forno
1. Pre-heat the oven to 220C/ gas mark 7.

2. Heat the olive oil in a hot pan. Grate the onion and carrot and crush the garlic before frying together. Season with the bay leaf, a pinch of oregano, Worcestershire sauce and a little salt and pepper. Allow the onion to soften before making a well in the centre of the pan. Place the mince in the middle of the pan and stir to break it up. Add the tomato puree and allow to cook out for 30 seconds. Continue until all the meat has browned nicely. Add the wine and cook off the alcohol before adding the tomatoes. Leave to simmer for a further 2-3 minutes. Finally add the milk, turn off the heat and set aside (watch Gordon's video on how to prepare bolognaise).

3. To make the cheese sauce, first melt the butter in a saucepan. Add the flour and using a wooden spoon, stir to form a paste. Over a gentle heat add a third of the milk, whisking to prevent any lumps forming. Add the rest of the milk a third at a time, whisking as you go. Season with salt and pepper and a pinch of ground nutmeg. Allow the sauce to cook out for another minute before adding the Cheddar cheese. Stir and remove from the heat (watch Gordon's video on how to make the best white sauce).

4. Spoon half of the meat sauce into the bottom of the baking dish and place pasta sheets on top (break the sheets if necessary to avoid any overlapping). Next, pour in just under half of the cheese sauce, and spread evenly using a spatula before spooning the remaining meat on top. Add the final layer of pasta and use the spatula to pour over the remaining cheese sauce.

5. Finish with the grated Parmesan and sprinkle with another pinch of oregano. Add a light seasoning of salt and pepper before cleaning the edges of the dish and placing in the oven to bake for 20-25 minutes, or until golden brown.

6. In the bottom of your salad bowl use a fork to whisk together the mustard, vinegar and olive oil. Season with salt and pepper. Carefully open the head of lettuce, season inside with salt and pepper. Upend the lettuce headfirst into the salad bowl. Holding the root, wipe the leaves around the bowl to coat in the vinaigrette. Twist the root and pull it out. Turn the dressed head of lettuce onto a large plate and gently open out.

7. Portion out the lasagne and serve alongside the salad.
