Foodbeast Chris came up with the idea during a Twitch stream, and found a pretty cool way to incorporate onions into ice cream and make it simple.
By using caramelized onions, food-grade dry ice, heavy cream, and condensed milk, he was able to make ice cream with the texture of ultra-creamy soft serve, all in under an hour.
I’m relatively open to savory ice cream flavors, having made one with garlic chili oil last year. That didn’t stop me from being skeptical if this recipe could work, but curiosity beckoned me to sample a scoop after the stream.
Honestly, I was surprised by the taste of this onion ice cream. The sweetness of the caramelized onions, combined with the richness of the ice cream, reminded me of eating Animal-Style fries and a milkshake from In-N-Out. I wasn’t mad at it.
If you want to give it a try or have the recipe to make that easy, quick ice cream base at home, all the details are below.
- 2 cups heavy cream
- 1 can sweetened condensed milk (14 oz)
- 2 small sweet onions, diced
- 1 lb food grade dry ice
- Salt to taste
For those looking for dry ice, several grocery store chains typically carry some for sale. Contact them ahead of time to see if they have any available.
- Dice your onions and slowly caramelize over low heat.
- Make your ice cream base by blending heavy cream and sweetened condensed milk until thick and creamy.
- Add the base to the bowl of a stand mixer and churn at a low speed.
- Break your dry ice into a fine powder, then slowly drop the powder into your stand mixer, one spoonful at a time. GO SLOW HERE!
- Once all of the dry ice sublimates, you can add the next spoonful. Ensure no chunks remain, as the ice cream isn’t safe to eat until all of the dry ice dissipates.
- As the ice cream starts to freeze, add your onions and increase the speed.
- Once the ice cream has thickened to a soft-serve consistency, you can serve as is or get into the freezer to chill for a couple of hours.
- We chose to pipe ours into a hollowed-out onion to serve, but a regular bowl also works!
