Description
This creamy potato soup gets its depth from slow-caramelised onions, a quick deglaze, and a fragrant herb simmer. Blend until silky, then finish with lemon and olive oil for a lighter, brighter bowl at home.
Ingredients
Scale
- 2 tbsp Butter
- 1nLarge onion (1, finely sliced)
- 2 cloves Garlic ( minced)
- 680 g / 1½ lb Yukon Gold potatoes (cut into 2.5 cm / 1-inch cubes – about 4 packed cups)
- 4 cups Broth
- 1-2 cups Water (as needed)
- ¼ cup White wine or vinegar ( for deglazing)
- 1 tsp Kosher salt (then adjust)
- 1 tsp Ground black pepper
- Fresh rosemary + thyme (1 sprig each, plus extra to finish)
- 1 Bay leaf
- 1 tbsp Fresh lemon juice
- Extra-virgin olive oil (up to 4 tbsp, to serve, optional)
Instructions
- Heat a Dutch oven over medium heat.
- Add the butter plus a small drizzle of oil, and warm until the butter is melted and foamy (that’s your signal to start cooking).
- Add the sliced onion, season with a small pinch of salt, and stir to coat.
- Cook, stirring about every 5 minutes, until it goes soft → golden → deep golden-brown. If it sticks or dries out: add 1 tbsp water or broth, scrape the bottom, and keep going (you may use up to ~60 ml / ¼ cup total).
- Stir in the minced garlic for 1 minute, just until fragrant—don’t let it brown.
- Pour in the white wine or vinegar and scrape up all the browned bits from the bottom of the pot.
- Let it simmer for 3–5 minutes, until the liquid is mostly absorbed.
- Add the potatoes, broth, salt, pepper, rosemary, thyme, and bay leaf.
- Bring to a boil, then reduce to a gentle simmer for about 20 minutes, until the potatoes are very tender (a knife should slide in easily).
- Remove the herb stems and bay leaf, then add the lemon juice.
- Blend with an immersion blender until smooth and velvety (or use a blender in batches).
- Taste and adjust salt, pepper, and lemon in small increments.
- Ladle into bowls, finish with a drizzle of extra-virgin olive oil and a sprinkle of fresh herbs.
- Serve immediately, piping hot.
