Base Ingredients
- 2 tablespoons Butter (Substitution Note: Use ghee or olive oil for lactose-intolerance.)
- 1 tablespoon Extra Virgin Olive Oil (Optional garnish for a finishing touch.)
- 2 cups Vidalia Onion, thinly sliced into ¼” rings
- 3 cloves Garlic, minced
- 4 cups Yukon Gold Potatoes, diced into 1″ cubes (skins optional)
- 4 cups Broth (Chicken or Vegetable, chicken bone broth preferred)
- 1 cup Water
- 1/2 cup Dry White Wine (Substitution Note: Use additional broth if omitted.)
- 1 teaspoon Kosher Salt
- 1/2 teaspoon Ground Pepper
- 1 bay leaf
Herbs and Garnishes
- 1 tablespoon Fresh Rosemary (plus extra sprigs for garnish)
- 1 tablespoon Fresh Thyme (plus extra sprigs for garnish)
- 2 tablespoons Fresh Lemon Juice (added before serving to brighten flavor)
Instructions
- Prepare the Dutch Oven: Warm your Dutch oven over medium heat and add the butter along with a splash of olive oil. Heat until it begins to foam beautifully, ensuring a rich flavor base.
- Caramelize the Onions: Add the thinly sliced Vidalia onions with a sprinkle of kosher salt. Sauté the onions, stirring every 5 minutes, until they caramelize into a deep golden brown color. This process takes about 30-40 minutes and develops the soup’s sweetness and depth.
- Add the Garlic: Once the onions are caramelized, stir in the minced garlic. Cook for about 1 minute until the garlic becomes aromatic and fragrant but not browned to avoid bitterness.
- Deglaze with Wine: Pour in the dry white wine to deglaze the pot, scraping any flavorful bits stuck to the bottom. Let the wine cook down and absorb mostly for 3-5 minutes, enriching the soup’s complexity.
- Add Potatoes and Broth: Stir in the diced Yukon Gold potatoes, chicken or vegetable broth, water, kosher salt, ground pepper, fresh rosemary, fresh thyme, and bay leaf. Bring the mixture to a boil.
- Simmer the Soup: Reduce the heat and let the soup simmer gently for 20 minutes or until the potatoes are tender and easily pierced with a fork.
- Blend the Soup: Remove the bay leaf and fresh herb sprigs. Add fresh lemon juice, then use an immersion blender to blend the soup directly in the pot until it achieves a silky smooth texture, enhancing its creamy consistency.
- Adjust and Serve: Taste the soup and adjust seasoning as necessary with additional salt or pepper. Serve hot, drizzled with extra virgin olive oil and garnished with sprigs of fresh rosemary or thyme for a beautiful presentation.
Notes
- For lactose-intolerant individuals, substitute butter with ghee or olive oil.
- If you prefer a vegan version, use vegetable broth and olive oil instead of butter.
- Keeping potato skins on adds extra fiber and nutrients but can be peeled for smoother texture.
- If omitting white wine, replace it with equal parts broth to maintain flavor balance.
- Slow caramelization of onions is key for deep flavor development; avoid rushing this step by increasing heat.
- This soup can be stored in the refrigerator for up to 3 days or frozen for up to 2 months.
