Jerusalem artichokes, roasted with mushrooms and onions

 I used to believe that Jerusalem artichokes were out of bounds because they cause terrible flatulence, but I got some from waitrose recently and they were no trouble at all (and delicious). This recipe worked very well, but see the modifications below!

Serves 4. Prep 10 minutes. Cook 45 minutes in the oven.

Ingredients

1 ½ lb (700 g) Jerusalem artichokes

2 onions

A few sprigs of fresh thyme

4 ½ tbsp olive oil

1 lb (450g) chestnut mushrooms (less will do)

1 oz (20g) butter

Salt and pepper etc 

 

Method (see below for advice on simplifying this)

1. Heat the oven to 230º C or gas mark 8.
2. Cut the artichokes into even sized pieces (large). Cut the onions into wedges. Put all these in a large roasting tin, in a single layer. 
3. Toss in 2 ½ tbsp of the oil. Season with salt and black pepper as you wish.
4. Roast these for 35 minutes, turning occasionally.
5. Cut the mushrooms in half. 
6. Put the mushrooms in another roasting pan with half the butter and 2 tbsp of oil. Roast for 30 minutes till golden, turning occasionally.
7. For the last ten minutes add the rest of the butter to the artichokes,
8. Throw the contents of both pans together and serve.
