The process of caramelization.. slow and sweet, slow and sweet. And did I mention worth it? When I worked as an apprentice to a french chef.. we would start onions for soup in the morning like this and let them caramelize long and slow most of the day. That was probably the best soup I ever had. Those onions would be stirred into a rich beef broth, with a splash of brandy, crusty french rustic toast and topped with a perfect combination of fontina, gruyere & provolone. Mmm. Perfection.
But were not making soup today and I promise, this won't take all day. Today we are making the perfect side of syrupy balsamic caramelized onions that, yes, do take time, but go well with a variety of dishes. They are great to make ahead and top grilled steak, pork tenderloin or chops, pizza, baked brie and even as-is for a nice bruschetta. It's that good.
Peppers and garlic are optional.. but to accompany steak, I'm gonna say.. they are a must. Having this on hand will instantly transform simple-easy meals into something really special. Make this dish when you have a couple of hours and a closet to clean, or laundry to do.. it does not need constant minding but will take the better part of 2 hours or so.
Caramelized Balsalmic Onions & Peppers
A
note on onion selection.. Sweet onions will render a sweeter finish and I
really prefer a mix of sweet and red. Red onions hold their structure
better when cooking for a long time. Which means in the end product you
can recognize an onion, I kinda like that... while the sweet onions
really are the ones that caramelize best and make a better tasting
finish. So, I suggest using both. I also add the peppers quite a bit
later as I don't like it when they disintegrate into unrecognizable
mush.
Caramelized Balsalmic Onions & Peppers
2 T. Olive Oil
4 lg. onions (sweet & red), sliced 1/2" thick
1 t. kosher salt
1/2 t. cracked pepper
1 red pepper, sliced 1/2" thick
4 cloves of garlic, chopped
1/3 c. balsamic vinegar
1/4 c. chicken broth (low sodium)
In a large bottomed pan (I prefer cast-iron), heat olive oil over med heat... add onions, season with S+P and cook for 10 minutes.
Add pepper, cook another 10 minutes.
Add garlic, cook 2-3 minutes.
Add balsalmic and chicken broth. Turn heat down to a low and let simmer, stirring occasionally for a minimum of 20 minutes and up to an hour.
*When done, taste for balance. Depending on the variety of onions and brand of balsamic used... can render a sweeter or not-sweet-enough finished product. Simple fix.. If at the end you would like it sweeter, I recommend a drizzle of agave or honey. It will not alter the flavor but will balance out acidity. Just don't over-do it. And then take note for next time, which onions/balsamic work best for you. Just remember... Long, low and slow renders onions sweet and caramelized. The longer the better!

This batch was mostly red, but it's best to use a combo of sweet & red. |
|
Season with salt. |
|
Onions have sweated down & carmelization is gonna start. |
|
Time to add the peppers. |

Adding the peppers later, keeps the integrity of their structure instead of turning to mush. |

Adding the garlic, so it cooks just enough and doesn't burn. |
|

|
Simmer, simmer, simmering the day away. |
