Author Notes

I love how onions become meltingly tender and sweet after a long roast in the oven, but it’s not such an elegant look to plop roasted onions on a platter. Here the petals stay together in a pretty rosette, thanks to a muffin pan. If you don’t have one, use a small rimmed baking sheet or an ovenproof dish and pack the onions tightly together.

To store: Refrigerate in an airtight container for up to 4 days. Tip: If the stem is the North Pole, you’re cutting through the onion’s equator.

I may be blind but where is the temp?

bobbi September 25, 2023

Has anyone made these ahead in the freezer? I think this would be great for Thanksgiving

I made these when I was already roasting a sheet pan dinner. I have a silicone muffin pan. There was no ghee to be found in my fridge, so I used butter flavored popcorn oil. The onions came out great- we ate a couple with dinner and I saved the other 4 to use in cooking new dishes- it's good to have cooked onions in reserve.

Do you peel the onions?

kathy December 20, 2020

The first time I made these, I used the muffin tins but I had to discard some of the onion in order to get them to fit. Subsequent times, I've just placed them cut side up on parchment lined half sheet pan. Latest onions were really large so I should have cooked them ½ hour longer. I love onions and really like this recipe. Be sure to use ghee ... I get it at Trader Joe.

I'm embarrassed to say how many of these I ate!! They were so delicious and so easy.

Jennifer S. November 15, 2020

So delicious! We followed the recipe as it is, and my husband can’t stop eating these beauties (they sure are pretty).

I skeptically sacrificed three onions and some real butter but made other veggie sides just in case. Tops blackened a little bit so I was even more doubtful. We ate all six onion halves! Fantastic alone and also mingled with mashed potatoes. And there was a request to add it to the meal rotation.

Ann M. October 23, 2020

I followed this recipe exactly. After the 1st 20 minutes I applied the butter and put them back in the oven. After 15 minutes the kitchen was filled with smoke and all of the onions were completely blackened on the bottom. If I ever try this againAfter applying the butter I would turn the oven downTo probably 300

Ann M. October 23, 2020

300 or less not to mention that my tin is comletely ruined. No amount of soaking and srubbing will remove the burnt on onion. Muffins can bever be made in this tin again..it is trash

kayvee March 13, 2022

Sorry you had that experience but appreciate the head's up! I haven't tried them yet. I'll use my silicone muffin liners when I do.

Carrie S. October 11, 2020

This were super easy, and look great! I only used 3 onions cut in half and filled the other empty holes with whole garlics and a sweet potato cut in half to multi task the recipe, worked well. Serving these as a side with smoked brisket, YUM!

Victoria N. October 7, 2020

These look really yummy. What do you serve them with?

Amy M. October 19, 2020

I served them with grilled steak and broccoli!

Amy M. October 5, 2020

These look amazing! I’m wondering if the wells should be oiled / sprayed so they don’t stick?

Victoria N. October 7, 2020

I would use butter or a cooking spray, for sure.

FAQs

How do you melt onions? ›

Melt the butter in the stockpot over medium-low heat. Add the sliced onions. Keep your eye on the onions and stir often at the beginning to allow all the slices to have contact with the bottom of the pot so they start to release their liquid. In about 45 minutes they should have released a good amount of liquid.

How do you melt onions quickly? ›

Points to remember
  1. Melt a small amount of butter and oil in a shallow pan over a low heat.
  2. Let the butter melt until it starts to sizzle.
  3. Add the finely chopped onions. Ensure the onions are coated in the oil and butter and allow to sizzle as it cooks.
  4. After about 12 minutes, the onions will become almost translucent.

Do onions melt when cooked? ›

Onions lose their bite and melt in your mouth when they're sliced and roasted with butter and fresh herbs and then tenderized further by braising in broth. Serve alongside roasted chicken or cook them in vegetable broth for an easy, elegant vegetarian side dish.

What is the best way to make onions taste sweeter? ›

Submerge Them in Cold Water

Soak them for at least 15 minutes (longer is even more beneficial), properly drain, and eat away! Submerging them in cold water takes away that intense, sharp bite from the raw onion. The cold water helps the enzyme that causes onions to have their pungent flavor to leach out.

How do you increase the flavor of onions? ›

How you treat them changes their flavor:
  1. Macerate them in vinegar and they become acidic yet sweet.
  2. Lightly cook them in a pan without browning them for about 10 minutes and they're subtle and savory.
  3. Sweat them like this even longer and their flavor gets more complex and concentrated.

How do onions become sweet when cooked? ›

When cooked, the heat raises the temperature in their cells until at a certain point, the complex chain molecules break down into simple sugars. This reaction … called pyrolysis (pie-rawl-asis), is what causes sautéed onions to brown and develop a sweeter flavor.

What is the best way to soften onions? ›

To soften the taste of raw onions, slice them thinly or cut them into larger chunks and soak them in very cold water for about 15 minutes. This will soften the taste, making them ideally suited for a salad.

Can you soften onions in the microwave? ›

Instead of spending 15 minutes trying to soften onions in a pan (only to scorch them!), try this microwave method. Pop chopped or sliced onions in a bowl, add a spoonful of water, cover with a plate and microwave on high for 3-4min. Carefully remove (the bowl will be very hot) and uncover.

What happens when you microwave onions? ›

Yes, you can cook onions in the microwave without any oil or butter. Onions naturally contain a high water content, so they will steam and cook in their own moisture. This method is a healthier option and can still yield deliciously cooked onions.

How do you melt onions in gravy? ›

Slice the onions to about ½ inch thick, try to make them the same size so they cook evenly. Melt 4 TBS butter in a pot over medium heat and add the sliced onions. Cover partially and let them simmer, soften, and reduce for about 25 minutes. Stir every few minutes and reduce heat if they start cooking too quickly.
