In anew Instagram post, the chef shared the full recipe, and its incredibly simple.

Heres how to make them.

Honestly, we wouldnt be surprised if you just need to buy some onions to make this breezy app!

Put the onions on the cutting board root end down.

Bring a medium pot of water to a boil and drop your onions in.

Cook the onions in the water for 4 to 5 minutes, or until tender.

Remove from the water and cool down.

Then, grab a parchment-lined baking sheet and arrange your onions on the pan.

Drizzle each onion with extra-virgin olive oil and season with salt and pepper.

Place the pan in the oven and roast your onions for 25 to 30 minutes.

While theyre roasting, Guarnaschelli uses the time to make her glaze.

This should take about 2 to 3 minutes.

This is an appetizer that definitely will look as delicious as it tastes.

And if you already have your Thanksgiving menu planned, these onions are easy enough to serve anytime.

They are stunning next to grilled steaks or fish, Guarnaschelli says.

These can also add great flair to a vegetable platter.
