Oh my gosh you guys, this chicken recipe is so good. I mean, anything with caramelized onions is so good. Like, caramelized onions. What could be bad? But this onion garlic brown sugar chicken takes the sauteed onion goodness and couples it with brown sugar and garlic to make a taste explosion that is out of this world. (Yes, I added caramelized onions and loads of brown sugar to my chicken. No, that’s not healthy. No, I never claimed to be a health food blogger. We do easy and delicious food here, not healthy and complicated.)
But first, the obvious question all of you are asking is: how do you caramelize onions? Well, let’s get to it.
How to Caramelize Onions
Low and slow is the key here. You want a low flame, so the onions really have time to release their juices and caramelize into a nice golden brown. If the flame is too high, the onions will get burnt before they caramelize. (Although to be honest, I do sometimes fry my onions on a higher flame to get them done faster. They still taste good, but they are not super sweet caramelized onions.)
Start off by putting your pan on medium-high heat. Add oil or butter and wait for it to heat up and for the oil to shimmer slightly or for the butter to melt. Put in your thinly sliced onions, and lower the flame to low. And then you wait. And wait. And wait some more.

Stir every so often so the onions don’t stick to the bottom of the pan and burn. After 15 or so minutes, once the onions are already starting to brown, add a spoonful of brown sugar. Keep cooking until the brown sugar dissolves and the onions are dark golden brown.

And there you have it! Perfectly caramelized onions. And the perfect use for perfectly caramelized onions is onion garlic brown sugar chicken!
How do you make Onion Garlic Brown Sugar Chicken?
(Don’t worry, exact ingredients and measurements are in the recipe card at the bottom of this post.)
Step one: spice the chicken
Lay three or four pieces of chicken on the bone in a 9 by 13 inch baking pan. You can use tops or bottoms, whichever you prefer. (I like tops. My family likes bottoms. Thus when I make chicken I do one breast for me, and two thigh-leg combos for hubby and the kids.)
Generously spice the chicken pieces with salt, pepper, garlic powder, onion powder, and paprika. Set the chicken aside while you start on the onions.

Step two: caramelize the onions and garlic
Caramelize the onions according to the steps outlined above. When the onions are nearly done, and before you add the brown sugar, add some diced garlic, and let the garlic caramelize as well. Garlic cooks much faster than onion, so you don’t want to start caramelizing them at the same time. Once the garlic is added to the pan, start stirring more often. After about five minutes, add brown sugar. Keep cooking and stirring until the brown sugar melts. And there you have it! The delicious caramelized onion garlic mixture to add to your chicken!

Step three: smother that chicken!
Spoon the caramelized onion mixture on top of the chicken pieces, until the chicken is entirely smothered in onions.

Step four: bake
Cover the chicken pan and bake it for a few hours. Yes, you read that right. A few hours. Let the onions continue caramelizing and the flavor penetrate the chicken.
Ok, ok, I happen to cook all my chicken for hours; I think it tastes a lot better that way. But if you are part of the other 99.999999% of the population, feel free to cook the chicken for shorter. Just make sure that the chicken gets fully cooked – you can tell by sticking a knife into one of the fattest parts of the chicken (breast or top of the leg.) If the juices run clear, you are good. If it’s still kinda red-ish, your chicken needs to go back in the oven.

Step five: Enjoy your onion garlic brown sugar chicken!
You can serve this chicken with rice, mashed or roasted potatoes, orzo, corn muffins, really anything. I served it here with white potato and sweet potato fries. (We gotta get some healthy food in there. And sweet potato is healthy, right?) (Shhh don’t disabuse me of that notion, ignorance is bliss and all that)

And that, my friends, is how you make this delectably delightful brown sugar chicken.
Ooh, delectably delightful, I like that. Or maybe delightfully delectable is better. What do you think?

Can I use boneless chicken
Can you use boneless chicken
Sometimes I carmelize onions by adding water right after the onions are fried enough to be translucent. If you add some water, and saute them until the water boils off, the onions get that beautiful brown color and are as sweet as onions that are fried the entire time.
That’s such an interesting idea. I’ll have to try it!
Such perfect onions! I can hardly ever get mine to caramelize evenly.

This looks and sounds absolutely gorgeous! Chicken is about my favourite meat (bar lamb) and I’m loving the way you’ve cooked it with the caramelized onions! You’re spot on, whenever I caramelize onions, the heat is barely on – low and slow is the way to go! Great recipe! x
