Preheat the oven to 350ºF (180°C). Wash and dry the potatoes. Prick each one with a fork a few times to let steam escape during baking. Wrap them in foil and place them on the center oven rack. Bake for about 1 hour or until tender. Once cooked, let the potatoes cool completely so they’re easier to handle.
6-8 potatoes
While the potatoes are baking, cook the bacon. Heat a skillet over medium-high heat, lay the bacon strips flat, and let them cook for about 10 minutes, flipping occasionally, until they’re golden and crispy. Transfer the cooked bacon to a plate lined with paper towels to absorb the grease. Once cooled, chop it into large pieces.
4-6 bacon strips
While the bacon rests, peel and finely dice the onion. In a large saucepan, melt the butter over medium-low heat. Add the diced onion and cook for 8–10 minutes, stirring occasionally, until it’s soft and translucent without browning.
3 tablespoons butter, 1 onion
Once the potatoes have cooled, cut them into halves or quarters and add them to the saucepan. Pour in the vegetable stock and stir well. Bring everything to a boil, then reduce the heat to low and let it simmer gently for 10 minutes to combine the flavors.
6 cups vegetable stock
Using an immersion blender, puree the soup in the pot until smooth and creamy. (If using a regular blender, allow the soup to cool slightly before blending in batches to avoid splatters.) Taste and season with salt and pepper as needed.
Salt and pepper
To serve, ladle the soup into bowls and top with a dollop of sour cream, crispy bacon pieces, and a sprinkle of fresh herbs like parsley or chives. Enjoy!
