Loaded Baked Potato & Leek Soup

Pale yellow soup in a round white bowl, topped with shredded cheese, chopped bacon and chives

If You Love a Loaded baked potato, You will love this soup. 

This is my favorite potato soup ever. It has a little heat due to the pepper jack cheese and hot paprika, but you can skip those and sub any of your favorite cheese if you want. It’s just a warm and cozy meal in a bowl and the ultimate comfort food. 

Step by Step Instructions

Preheat oven to 375°F/190°C/Gas Mark 5. Wash potatoes and pierce several times with a fork or sharp knife. Place directly on oven rack and bake for 45 minutes or until fork pierces easily all the way to the center. Let cool enough to handle. 

Two baked potatoes on a wood cutting board. One has a fork pierced through it.

Trim the root off of the leeks, leaving as much of the white part as you can. Discard the darker green parts or save them for a future stock.

Cut them in half vertically, then slice again horizontally into several pieces.

Place leek slices in a bowl of water, swirl around to get the dirt and sand out from between the layers. Let sit until the debris has settled to the bottom of the bowl. Do not dump the water out. Instead, gently scoop them out without disturbing the dirt at the bottom of bowl.

Chopped leeks rinsed in a clear glass bowl sitting on a wood board. The dark part of the leeks are laying in the background.

Melt butter in a dutch oven or soup pot on medium, add the leeks and a large pinch of salt. Cook this, stirring occasional for about 10 minutes or until leeks have softened.

Stir in the garlic and cook for one more minute, then add the stock and two cups of water, hot paprika, white pepper and simmer for about 20 minutes or until leeks are very tender.

Cut one of the potatoes in half lengthwise and scoop out the inside with a large spoon, then cut the potato in 1/2”/1.27cm cubes and set aside (this will go in as chunks at the end).

Meanwhile, chop the entire remaining potato and the skin from the first potato, and add to the pot.

A Stick Blender Makes this Much Easier

Purée the contents of the pot with a stick blender until smooth. If you don’t have a stick blender you can do this in batches in a stand blender, but be very careful when removing the lid of the blender as hot liquids can create pressure and burst out and burn you.

Whisk in the sour cream. Once smooth, add the milk and 1/2 cup each of both cheeses. Stir in the reserved potato cubes, taste and season with more salt if needed. If soup is too thick, you can thin with a bit of water.

Notes

You can microwave your potatoes instead of baking if you’re in a hurry. Pierce them with fork or sharp knife, cover and microwave for 3 minutes, let rest for 3 minutes, repeat process until fork tender all the way through. Careful not to over microwave or they will be rubbery.
