I guess I didn't check the size of the bag of onions I was buying in that online grocery order too closely . . . because it ended up being huge! I decided to create something with some of them that we would both find delicious. We love gratins . . . and so I thought an onion gratin type of dish would work really well.
I roasted the onions in a hot oven first of all, in a mix of butter and olive oil. This slightly caramelized them, helping to bring out their natural sweetness. I do so love the flavour of caramelized onions don't you?
I whisked together some double cream (naughty naughty) a bit of Dijon mustard and some Parmesan cheese, which I poured over and around the onions.
They were then returned to the oven until the cream was golden brown and bubbling and all of the lovely onion juices had melded withit to create a very delicious sauce. You could add some garlic to the cream as well if you wished . . . a small clove crushed would be enough.
Altogether this was very satisfying and we both quite enjoyed it. With a bit of crusty bread it went down a real treat.
*Roasted Onions with a Parmesan Cream*Serves 4 (as a side)
Put the butter and oil into the baking dish. Put it into the oven to heat while you prep the onions. To prep the onions, peel, leaving the root end intact as much as possible and then cut them in half down through the centre through to the root end. If you have been careful enough to keep the root intact, the onions will stay together when they cook. Remove the baking dish from the oven. Place the onions into it in a single layer, cut side down. Season with salt and black pepper. Roast in the heated oven for 15 minutes. Remove from the oven and flip over. Season again and return to the oven to roast for a further 15 minutes, until beginning to caramelize a bit on the edges. Remove from the oven.
Wait til you see what I did next!
I hate to waste anything and so I used the leftovers to create a simple pasta dish for us to enjoy the day after. It was as simple as cooking some pasta, pureeing the leftovers and tossing the whole lot together. Boy was it good!
