Caramelized Onion Recipe

This classic caramelized onion recipe is slow-cooked until dark brown, tender, and loaded with delicious sweet and savory flavors.

Once you learn how to do this properly, you’ll never want a caramelized onion again.

INGREDIENTS:

– yellow onions – red onion – unsalted butter – apple cider vinegar – coarse salt

Slice the onions about 1/8” to ¼” thick.

Add the butter to a large, thick-bottomed stainless-steel pan or pot or a large cast iron skillet and heat over medium heat.

Cover and let the onions stand untouched for 5 to 6 minutes.

Remove the lid, and you’ll notice the onion liquid will be evaporated. Stir the onions for 1 to 2 minutes.

Turn the heat to low-to-low medium and stir every 6 to 8 minutes for 30 to 35 minutes or until very dark brown.
