Because caramelized onions green beans has that classy look, and taste, to it. And yes I realized I am talking about green beans here.

Green Beans and Onions

Green beans, like a lot of veggies, are way underrated. It is often misunderstood. Never really a kid favorite. And quite frankly, isn’t cooked very well most of the time.

But I believe in green beans. I also believe green beans don’t have to be smothered in cream to be yummy.

Don’t get me wrong, I do like them smothered in cream (and cheese, and condensed mushroom soup), so don’t deprive me of creamy yummy green beans, please….

But what I’m saying is, green beans has so much more potential than that. Way more than a smothered-in-cream kinda veggie.

And here’s my secret: green beans and onions. Or more specifically, caramelized onions where onions are sautéed in butter until it is soft and sweet, then we add a pinch of salt to it to open up the flavors.

If you haven’t had green beans with caramelized onions, get ready to be blown away.

Sautéing Caramelized Onions Sautéed Green Beans in non-stick skillet

Caramelized Onions

This is truly the secret ingredient to this dish. One of my favorite things about onions is that when cooked, it transforms from being pungent and spicy to sweet and flavorful.

Also, have you sautéed onions and smell the lovely aroma of caramelized onions on a skillet?

Omg. I love the way my kitchen smells whenever I make caramelized onions. I live for my kitchen smelling like caramelized onions…

No words. No words to describe the gorgeous flavors and textures these caramelized onions bring to the green beans.

All you need to do is sauté the sliced onions in butter under medium to medium high heat. Once it turns soft and slightly brown, sprinkle some salt, and viola – caramelized onions!

Check out the before and after pics. Notice that after the onions are caramelized, it will turn brown, shrink, and become crazy delicious.

Tips and Tricks

The truth is, It is such a simple recipe, but one that produces so much great flavors, and definitely not simplistic. Here are some tips!

  • Use a large skillet (the largest one you have!) that retains heat really well.
  • At the beginning, We are sautéing the onions and green beans separately because both cook at different rate and we want to make sure we cook them before bringing them together. This also prevents the skillet from being overcrowded and subsequently cooking the ingredients unevenly.
  • If you are feeding a lot of people and want to double or triple the recipe, make sure you are not crowding the skillet when you sauté the green beans. Sauté green beans in batches if necessary!
  • I like my green beans slightly charred (see pictures for the beautiful char-ness), but if you don’t like the slight char, simply lower the heat, cook the green beans slower, and remove them promptly once they look done.

    Such an epic combo! We had this today with a little bacon too and it was sooooo good!

  14. Have you ever made this in advance and frozen them in a ziploc?

    1. Joyous Apron says:

      I have not. The texture of the green beans may change a bit (less crunchy, more soggy) – other than that I think it should be fine!
