Caramelized Onion Soup

Caramelized Onion Soup

Caramelized onion soup is one of my favorite onion recipes! I love making this soup in the fall and winter months because it’s so warming and nourishing! Onions are a wonderful healing food for our bodies. Onions are nutrient-dense and offer many health benefits when added to our diet on a regular basis.


I personally eat onions every day both raw and cooked. I love their taste and eat red, white, and yellow varieties. One of my favorite ways to enjoy onions is caramelized. The rich depth that comes from slow cooking onions over low heat creates a mouth-watering onion flavor that you can truly savor!


I usually make large batches of caramelized onions at one time and use them in a variety of different recipes. Some recipes that caramelized onions are fantastic in are dips, mashed potatoes, eggs, and soups.



Onions are a potent superfood from the allium family of vegetables. Onions are rich in sulfur an important mineral for vibrant health. Sulfur protects our heart and blood vessels and helps us build connective tissue and strong bones.


Onions are high in phytochemicals that protect our body from oxidative stress and disease. Quercetin is a flavonoid and antioxidant that is a fantastic anti-inflammatory that prevents oxidation of fatty acids in our body and keeps inflammation in check.


Onions also provide protection against colorectal, laryngeal, oral, esophageal cancer, and ovarian cancer, when you consume between 1-7 servings per week. For oral and esophageal cancer protection you need at least 1 serving per day. A serving consists of ½ cup per day.


Today’s recipe uses caramelized onions and vegetable stock as the base for a simple comforting hot soup that is perfect to enjoy on a chilly fall or winter day.

This is what the onions look like when they are halfway thru the caramelization process:



Caramelized Onion Soup

Paleo,Vegetarian, Gluten-Free, Nut-Free

Makes 2-4 servings


2 tablespoons virgin coconut oil or organic unsalted butter

2 large yellow onions-peeled and thinly sliced

2 teaspoons unrefined sea salt

1 tablespoon balsamic vinegar

4 small garlic cloves- peeled and grated

5 cups organic vegetable stock or chicken bone broth

½ cup white wine

1 bay leaf

2 teaspoons raw honey

2 sprigs fresh thyme

¼ teaspoon fresh ground black pepper


1. Melt coconut oil or butter in sauté pan or skillet over medium heat. Add the onion slices and sprinkle with 1 teaspoon of sea salt and balsamic vinegar if using.

2. Cook onions over medium-low heat until golden brown and caramelized, stirring occasionally to prevent burning. This should take 25-30 minutes. Add garlic during last 2 minutes of cooking.

3. Once onions and garlic are done cooking place in a medium-size pot. Add vegetable stock or bone broth, white wine if using, bay leaf, honey if using, thyme, black pepper and 1 teaspoon of sea salt. Cook soup on medium-low heat for 30 minutes to allow flavors to meld. Enjoy hot!

  1. This looks just awesome Shelley. I love French Onion soup and it’s finally cooling off enough here in the Islands to be able to enjoy things like this. I especially like to treat myself to our sweet Maui onions for things like this – yum!

    I started your 5 day detox yesterday so far so good. I feel like I always have something to eat on this plan so I haven’t been hungry, not really. Anyway – this onion soup is to die for. Sweet and savory at the same time. I have a question about the detox plan – could I add greens to this soup (like some kale) and still get all the benefits of the detox?

  3. This soup is seriously amazing. My boyfriend who is not on the cleanse (and is far from interested in ever doing one) tried mine and decided he’s having it for lunch too. “It’s very hot, and VERY good. Almost too good to be soup”, he said. I’ll be excited to try it after the cleanse too, with the addition of balsamic, wine and honey…(3 of my favorite things).

    • Jessica, Thanks so much for sharing how you and your boyfriend like the onion soup! I like to eat create recipes that taste good so you want to eat them and deliver nutrients that can help your body detox, repair, and heal itself. I’m so glad you and your boyfriend are enjoying this detox recipe and when you’re done you have to try it with the balsamic, wine, and honey too!

  4. Your soup looks amazing.I love to include lots of onions and garlic in my cooking. Caramelized onions taste wonderful and what better way to enjoy them but in a nice warm bowl of soup. I make a similar version of vegetarian onion soup, and it is always one of our favorite winter soups.
