Baked stuffed onions hit the bullseye if you are after the ultimate Christmas side dish to go with your roast turkey or glazed ham. To make them even more delicious they are also doused in parmesan cream.
The onions are rich, hearty, and delicious. So much more fun than a standard baked onion. Stuffing an onion really elevates the humble onion bulb into something rather magical.
They have become a firm family favourite. I often make them during the Australian winter with a roast. Christmas is only once a year, and these onions deserve to be eaten more than once.

What's in this post
Ingredients

- White Onions: Use white onions (salad onions) if you can as they have a milder and sweeter taste to brown or Spanish (red) onions. They are the perfect choice for stuffed baked onions.
- Salt: Flavour enhancer, used for seasoning.
- Parsley: Adds a herbaceous note to the stuffing. To change things up you could use thyme, basil, or even oregano.
- Pepper: A little seasoning kick to the stuffing.
- Cream: Use thick cream. Along with the parmesan creates a lovely sauce that gets between the onion layers.
- Ham: This can be omitted if you want to make them vegetarian.
- Parmesan: Finely grated it is mixed with the cream to create a delicious sauce.
- Breadcrumbs: Catches all the flavour from the cream and parmesan cheese.
- Garlic: Use one or two crushed cloves, depending on how much you love garlic.

I love recipes like that. We have heaps of newspaper cut outs that are family staples. I think our treat dish is probably the trifle. Everything else usually makes an appearance at other times.
Carole
Hi there. The current Food on Friday is all about onions! So it would be great if you linked this in. This is the link . Wishing you very happy Holidays!
Sara
Thanks Carole, I will check it out.

These are beautiful! I almost thought they were scallops at first. We stuff onions frequently in our cuisine (Persian) but never seen it with cheese. This looks delicious!
Sara
I will have to do a bit of a search for Persian stuffed onions, I imagine they would be lovely.
Christine @ Cooking Crusade
Wow I've never had stuffed onions before! These look divine. I usually whip out a trifle at Chrissy 😀
Sara
My sis-in-law is the trifle queen in our family, she always does one for Chrissy
Nic
This is very similar to a Jamie Oliver recipe. I tried it a couple of times and despite its deliciousness I decided life is too short to stuff an onion!
Sara
There are a family fave, and take no time to make, except the simmering of the actual onions. Then it is spooning the mixture in and banging them in the oven.
Gaby
I don't know why it never crossed my mind to stuff onions but it sounds delicious.
Sara
These guys are well worth making.
Robyn Little
