Full Recipe:
Ingredients:
- 2 tablespoons butter (use ghee for paleo/Whole30)
- 1 large Vidalia onion, thinly sliced into ¼” slices (about 2.5 – 3 cups)
- 2 cloves garlic, minced
- 24 oz Yukon gold potatoes, diced into 1″ cubes (around 4 heaping cups)
- 4 cups chicken bone broth (or any broth of your choice)
- 1-2 cups water
- ¼ cup dry white wine (or extra broth)
- 1 teaspoon kosher salt
- 1 teaspoon ground pepper
- 1 sprig fresh rosemary
- 1 sprig fresh thyme
- 1 bay leaf
- 1 tablespoon fresh lemon juice
- 4 tablespoons extra virgin olive oil (for garnish)
Directions:
- Heat a Dutch oven over medium heat. Add butter and a splash of olive oil, allowing the butter to melt and foam.
- Add the sliced onions and a pinch of salt. Sauté the onions, stirring every 5-10 minutes, until they soften, then caramelize. This will take about 30-40 minutes. Add water or broth in small amounts to keep the onions moist and prevent burning.
- Once onions are caramelized, add the minced garlic and sauté for 1 minute until fragrant.
- Deglaze the pot with white wine, cooking for 3-5 minutes until the wine is mostly absorbed.
- Add diced potatoes, broth, salt, pepper, rosemary, thyme, and the bay leaf. Bring to a boil, then reduce heat to low and simmer for 20 minutes, or until potatoes are tender.
- Remove the herb stems and bay leaf. Add the lemon juice and blend the soup with an immersion blender until smooth. Add additional water or broth if the soup is too thick.
- Taste and adjust seasoning. Ladle into bowls and drizzle with olive oil and fresh herbs. Serve immediately.

The Heartwarming Story of Caramelized Onion and Potato Soup
There’s something inherently comforting about a bowl of warm, velvety soup on a cool day. The Caramelized Onion and Potato Soup is not just a dish; it’s a sensory experience. From the deep, sweet aroma of onions caramelizing on the stovetop to the rich and creamy texture of pureed Yukon gold potatoes, this soup feels like a warm hug in a bowl.
At first glance, this might seem like a humble dish, but its simplicity is precisely what makes it special. This recipe highlights the natural flavors of its core ingredients—onions and potatoes—elevating them to new heights with a few careful techniques. The end result is a soup that’s both nourishing and deeply satisfying, without the need for any heavy creams or complex sauces. Perfect for those who appreciate the beauty of simplicity in the kitchen.
Why Caramelized Onions Make a Difference
One of the standout features of this soup is, of course, the caramelized onions. Onion soup recipes often get overlooked, but caramelizing onions is a game-changer. While it does take a bit of time and patience, the reward is well worth the effort. Caramelizing onions brings out their natural sweetness, creating layers of flavor that are unmatched by quick sautéing.
When onions caramelize, the natural sugars break down and intensify, resulting in a rich, golden-brown color and a wonderfully deep, sweet-savory taste. Unlike French onion soup, where caramelized onions are often swimming in broth, here the onions are blended with the creamy potatoes, creating a silky smooth soup that is both luxurious and filling.
The Power of Yukon Gold Potatoes
Yukon gold potatoes are the preferred variety for this soup, and for good reason. Known for their buttery, smooth texture, Yukon golds bring a natural creaminess to the soup without the need for dairy. Their slightly sweet, mellow flavor complements the sweetness of the caramelized onions, and when pureed, these potatoes turn the soup into a velvety masterpiece.
While russet potatoes can sometimes make soups feel a bit grainy or starchy, Yukon golds offer a much smoother, more refined consistency. For anyone seeking a creamy texture without adding heavy cream or milk, Yukon gold potatoes are the ideal choice.
Bone Broth for Added Nutrients
Though this soup can be made with any broth—vegetable, chicken, or even water—using bone broth is a great way to add extra depth, nutrients, and flavor. Bone broth, known for its high gelatin content, lends the soup a richer, thicker texture while also packing it with collagen and amino acids that promote gut health and joint function.
Bone broth has gained popularity in recent years for its health benefits, and incorporating it into soups like this one is an easy way to enhance the nutritional value of your meal. Whether you’re following a paleo or Whole30 diet, or simply looking for a way to boost your immune system, bone broth is a great addition to this recipe.
Customization Options
The beauty of this Caramelized Onion and Potato Soup is that it’s highly customizable to suit various dietary needs and preferences. The recipe is naturally gluten-free and can easily be adapted to be dairy-free by swapping out butter for ghee or olive oil. If you’re looking for a lighter version, you can use a vegetable broth or even water, although bone broth adds a particularly nourishing touch.
Another excellent feature of this recipe is its versatility when it comes to garnishes. A drizzle of extra virgin olive oil not only adds a touch of elegance but also brings a silky finish to the soup. Fresh herbs, like thyme or rosemary, brighten up the flavors and create a lovely contrast to the richness of the onions and potatoes. For an extra touch of luxury, consider adding a dollop of sour cream or a sprinkle of grated Parmesan cheese if you’re not adhering to a dairy-free diet.
If you want to add a bit of texture, homemade croutons or a handful of crispy bacon bits can be sprinkled on top. These elements add an irresistible crunch, balancing the smoothness of the soup.
Pairing Suggestions
This soup is incredibly hearty on its own, but pairing it with other dishes can turn it into a well-rounded meal. Crusty bread is an obvious choice, and for a truly indulgent experience, you can serve it with a slice of garlic bread or a side of warm, buttery dinner rolls.
For a lighter meal, pair this soup with a simple green salad, preferably one that has a tangy vinaigrette to cut through the richness of the potatoes and onions. A brussels sprouts salad with a lemony dressing or a butter lettuce salad would be ideal companions.
For those who prefer a protein-packed meal, this soup pairs wonderfully with rosemary-infused steak, a herb-crusted chicken breast, or a roast pork loin. The earthy flavors of rosemary, thyme, and garlic complement the sweetness of the caramelized onions, creating a harmonious balance between the soup and the main course.
Health Benefits of Caramelized Onion and Potato Soup
While many creamy soups rely on dairy for their luxurious texture, this Caramelized Onion and Potato Soup is a health-conscious alternative. By avoiding heavy cream, butter, or flour, this soup becomes a great option for those following gluten-free, paleo, or Whole30 diets. The use of bone broth adds a nutrient-dense component, rich in collagen, which supports joint and skin health. The onions and garlic provide natural anti-inflammatory properties, while the potatoes offer a good source of potassium and fiber.
For anyone seeking a heart-healthy, gut-friendly soup, this recipe is a fantastic option. Plus, it’s incredibly filling without being calorie-dense, making it an ideal choice for those looking to maintain or lose weight while still enjoying comforting, satisfying food.
Conclusion:
The Caramelized Onion and Potato Soup is a recipe that proves you don’t need fancy ingredients or complicated techniques to create a truly memorable dish. By focusing on quality ingredients and allowing them to shine, this soup manages to be both comforting and elegant at the same time.
