Recently I have been enjoying onions a lot and when I came across this recipe for roasted parmesan onions on Proud Italian Cook I knew that I had to try them soon. I thought that pairing them with the steak in green peppercorn sauce would be a nice fit. When you bake or roast onions they get all nice and soft and tender and they release their natural sweetness and they are just plain good! Add some melted golden brown cheese on top and a creamy wine sauce and you have one amazing side dish. The roasted onion gratin was an absolute treat! The onions were nice and tender and full of that magically sweet onion flavour. I am glad that I paired the onion gratin with such a strong main course as this side dish could easily steal the show from a lesser one. I have a feeling that these onions will be making a regular appearance on my dinner table.
Onion Gratin
A slow roasted sweet onion gratin with a cheesy cream sauce.
ingredients
- 4 large yellow onions, peeled and sliced into 1/4 inch slices
- olive oil
- salt and pepper to taste
- 1 teaspoon thyme, chopped
- 1 cup of heavy cream
- 1/4 cup of white wine
- 1/4 cup of parmigiano regginao (parmesan), grated
directions
- Spread the onion slices out in a baking dish and drizzle them with olive oil.
- Season with salt and pepper and sprinkle with the thyme.
- Bake in a preheated 375F/190C oven for 15 minutes.
- Meanwhile heat the heavy cream and wine in a sauce pan until it starts to bubble on the edges.
- Transfer the onions to a baking dish and spoon the cream onto.
- Cover in foil and bake for another 25 minutes.
- Remove the foil and sprinkle the cheese on top.
- Increase the temperature to 450F/230C and bake until golden brown, about 5 minutes.

Marc @ NoRecipes says
December 13, 2008 at 5:47 amOooo looks so good! The best part of an onion ring is the little bit of sweet caremelized onion in the center. You’ve taken the best part and covered it in cream and cheese. Awesome!

Rita says
December 13, 2008 at 9:48 pmKevin, we love onions here at home, and I would love to make those. I have a few questions though: Did you keep the onions on the same baking sheet all th etime or is it necessary to transfer? Also, were they covered during the first time baking, or just at the end to prevent from burning?
Thanks so much

Chocolate Shavings says
December 14, 2008 at 12:44 amWhat a great side dish! I grew up hating onions, and have only started liking them a couple years ago. I know try to make them in as many different ways to showcase its different facets. This definitely makes the cut!

December 15, 2008 at 8:11 amOh! I love the specks of thyme on the onions!! it looks so appetizing!
Kevin says
December 15, 2008 at 1:53 pmRita: The onions were first cooked on a baking sheet and then transferred to a baking dish when the sauce is added. When they are transferred to the baking dish they are covered in foil for the first while and then the foil is removed at the end so that the cheese can brown.

May 21, 2013 at 12:51 amI have made this several times now, twice with Texas 1015 sweet onions and a few times with large spring onions. Every time it is a raging success – even when I double or triple the recipe, it comes out fabulous every time. Thanks so much for sharing!
