Onion confit is made by sweating onions over low heat in a little olive oil and salt. Vegetable stock, vinegar, and fresh thyme finish the dish. Use as a recipe ingredient or condiment for sandwiches.
Making this onion confit is dead simple but it takes a bit of patience. We slowly sweat the onions over medium-low heat with salt and oil to not caramelize the onions.
Once the onions are soft, add the vegetable stock and white wine vinegar and simmer until the pan is dry.
Turn off the heat and add in fresh thyme leaves. That’s it. The whole recipe will take approximately 1 hour with minimal steps and attention paid.
I’ve included a quick video below and the recipe follows the video.
