Marinated Red Onions MAGIC ELIXIRS (TM)

I love a magic elixir–a special sauce or bit of magic that turns ordinary food into extraordinary. In my circle, I’m a little famous for the bowl of marinated red onions on my kitchen counter (we even call them “Counter Onions”!)…which is amusing, because how could I have known these onions would start a movement? From my Instagram stories you may know that I prize a beautiful entrée salad, and every entrée salad I make includes a bit of this oniony goodness. And there isn’t a simpler recipe.

I marinate my red onions in a high quality olive oil, red wine vinegar, and oregano. I leave them on my counter uncovered in a little ceramic dish to use every day on my eggs, in a hamburger, in a salad, or in a marinated entree. Daily I get reports on other creative ways people enjoy them–and my own children eat them right out of the bowl.

Make enough to use over two days, and if after two – four days you haven’t used them up, use the oil olive oil to make a salad dressing, sauce up the onions and enjoy them, or chop them up and put them in a chicken salad. They stay fresh about two days on the countertop. You might be asking yourself: why not put them in the refrigerator? I don’t, because when the oil solidifies, the magic is gone. After Heroine Chicken these simply delicious dish enhancers are my most talked about recipe, and deserve their own blog post–so let me know how you use yours!  They will perk up just about every savory  dish you make.

Q: It seems so hard to get one of your Marinated Onion bowls – how in the world do I get one? 

A: We are adding bowls every week.  You can message me with your email.  I have a short list of folks that I send an email to every week.  

Q: The onion bowls seem kind of expensive, why are they priced like that? 

A: Each one takes 10 days to make and is hand made by an artisan and each one is numbered and stamped.  

Q: What if I just can’t afford spend that much on an onion bowl? 

A: If it’s not something that is possible for you, I do regular giveaways.  So keep watching the stories and be sure to enter when we do them! 

Q: Why do you call them “counter onions”.

A: We call them “counter onions” because they meant to be served room temp and there is never a time that there isn’t a bowl or two on my counter, ready to go!  

Q: Why don’t you put them in the refrigerator?

A: I don’t put them in the refrigerator because the oil solidifies and when it does, the magic is gone. 

Q: How long are they good for? 

A: They are good for about 3-4 days. We enjoy the onions on everything and use the oil as a salad dressing or marinade.

Q: Do I need to cover these?

A: I don’t cover mine but if you live in a warm, tropical area or there is another reason that you need to, feel free. 

Q: Can I make the whole recipe in one bowl? (Whether I using the onion bowl or not)? Can I put the marinade in and then stir?  

A: It’s best to make the marinade and stir it up in a separate bowl.  Then slice your onions, keeping them intact.  Then gently place them into the bowl and pour the marinade over them.  If you mix it all together in one bowl, you will most likely separate the onions and they may stick out of the oil. 

Q: What do I do if I have onions sticking out of the top?

A: Then you probably have too many onions or they are not flat.  Be sure to follow the amount of onions called for in the recipe – 1 small, 1/2 medium or 1/4 of a large onion.  Be sure to keep them in slices and lay them flat as you put them in the bowl.  And make the marinade in a separate bowl. 

It’s important not to have them sticking up out of the oil, because they will go bad. 

Q: What if I don’t like oregano? 

A: I recommend doing just using 1/2 of the oregano. The marinade softens the taste of it so much so that you can barely taste it.

Q: Can I use fresh oregano? 

A: Since this is going to stay on the counter at room temperature you need to use dried oregano. Even though I love fresh herbs, dried is better here. 

Q: What about using white onions or a different viengar?

A: I love to improvise but I think that this recipe is best as is.  It’s not the same with a white onion, avocado oil or a different vinegar (although I have heard that people love pomegranate vinegar).  If you require a vinegar with no alcohol content, I know that there are some out there and using that as a substitute would be fine.

Q: Will there be an onion smell in my kitchen if I leave them uncovered on the counter? 

A: When you marinate onions and they are under the oil, you will not be able to smell them. (that is why it’s also important to follow the recipe and directions)

Q: Are the onions going to give me bad breath?

A: They should not give you onion breath, because the marinating is a gentle form of cooking so that removes the strong taste and smell. 

Q: What if I have too many marinated onions or leftover marinated onion oil past the day that they are good? 

A: Share with a friend or neighbor.  Or saute the extra onions up – the get crispy and lovely.  If you have leftover oil, marinate some protein like a chicken breast or a pork chop. You can use the oil in a salad dressing. Some people even freeze the oil in small containers and use them as a flavored oil for cooking. 

Q: What if I am a person that does not digest onions well?

A: If you feel like you can, then try them.  Since the marinade gently cooks the onions, they are more easily digestible.  But if onions don’t agree with you, then this dish just may not be for you. – then this dish may not be for you.

  1. I was so excited to try these! I followed the recipe exactly, using a great quality olive oil I order from Italy. But even after 3 days, they just tasted like very strong, raw, red onions with oil on them. Any ideas why? I am not an onion hater, I love cooked onions & like raw ones in recipes, but these were extremely strong. I wanted to love them as much as everyone else seems to.

    1. All onions are not equal, some will be stronger in flavor. Cut them in rings and leave them in rings and put them in a low flat bowl. Make the marinade in another dish a pour it over. If there are any onions sticking out, they will not marinade so pull them out. I think it is important to slice them thin as well. It sounds like you use a high quality extra virgin oil which is important, hopefully these tips help !

  2. I found In the FAQs your specific direction abt leaving the onion intact…AFTER I had made the recipe and wondered if it mattered my onion was not submerged (as I had not left the onion intact ?) Hopefully it’s not a waste of ingredients. That would have been helpful info in the recipe.

    1. It’s OK if you didn’t leave it intact. I would suggest doing so next time. If the onions are not submerged take those pieces out

    2. hi Steph, its ok if the onion wasn’t intact. i find it much easier to keep it marinated if it is intact. its not a waste of ingredients, simply pull out any onion not submerged under the marinade.

    1. ???????????Chicago girls rock

  3. Can I use avocado oil instead?

    1. No… Not if you’re wanting these results

    2. No, u will simply not get the magic

      1. so when my grandma gave me a batch of onions is this a good thing or a bad thing?

      2. It means your grandma loves you! These are so fabulous and you will love them!

  4. Can i use the leftover oil for something? To cook with or in a salad dressing?

  5. Can I please cover the marinade? I don’t want dust to get in the bowl and our kitchen counter is not big so there’s always some kind of work being done there. Thanks!

  6. These onions are fantastic. I eat them out of the bowl, in sandwiches, and salads. I feel like I am barely scrapping the surface though …. my brain isn’t built to find to find new dishes to add these onions to. Please, pretty please, post a list of some dishes that these fantastic onions will enhance. THANK YOU!

    1. If you scroll through the comments, you can see where Teri has tagged these onions as an addition to other recipes of hers!!

  7. These took my husband back to Upstate NY and the oil used on subs! Absolutely delish!!

  8. Still loving these magical things after a few years of making them. So delicious on all the things!

  9. Can we reuse the oil mixture for a new batch of onions?

    1. She says no on her IG. It gets too strong.

    1. Thanks for sharing! I love the onions and the marinade for so many things!

  10. Can we reuse the oil mixture for a new batch of onions? We wiped out the onions in one day and would love to simply add a few more. Please advise.

    1. that’s such a good question. No don’t use the marinade a second time for onions. Pour it on chicken breast or a pork chop and get it marinating in the fridge

  11. Pingback: - Abe's Table
    1. thanks love

  12. These Onions were fantastic! Quick question though- how long would you say the residual oil is good for, after the onions are gone? Thank you!

    1. This is what I would say. Just one set of onions to one side of marinade. Then get that marinade in the refrigerator and use it on a piece of protein to marinade.If you’re using the marinade every single day is your salad dressing you won’t have any left over… Hope that helps

  13. These onions are the easiest way to up level any meal. They are so versatile. I love to put them on my eggs in the morning, use them on my salad for lunch, and put them on my steak or chicken. The leftover dressing is fabulous to marinate chicken in. Admittedly, I eat them right out of the bow. I have several friends now who are making these weekly, as well.

    1. I love this… Thank you so much. You can’t believe how many children we have eating them directly out of the bowl. If I ever have any left over I sauté them up and they’re crunchy and wonderful on top of the salad. I use the dressing every day with my breakfast Greens so I normally don’t have much left over
