How can I thicken my leek and potato soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

Although leeks are known for its powerful taste, your potato and leek soup can occasionally come out bland. The reasons are usually two: you didn't season your soup at all, worrying it might be too salty because of the leeks; or you added to much water for the stock.

Why is my potato leek soup gummy? Potatoes should be diced in similar size so they cook evenly, but don't drive yourself crazy getting them teeny-tiny. If they're too small, you risk the potatoes releasing too much starch, which can make the soup gummy when pureed.

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

The most classic and surefire way to thicken a broth-based soup is with a cornstarch slurry. Whisk together equal parts cornstarch (or arrowroot) and water or broth, then whisk it into the pot of soup. A good ratio to get to a pleasant thickness without your soup tasting goopy or heavy is one tablespoon.

Add acidic ingredients.

Foods that have a great deal of acidity, like lemon juice, vinegar, white wine, and tomato puree, can help liven up the flavor of bland-tasting bone and other broths. "The acidity of these ingredients works to complement and enhance the broth's flavors, not mask it.

Add the leeks to the pot, lowering the heat if necessary and saute for 10-15 minutes , or until soft and translucent. Be careful not to burn the leeks, as they will impart a bitter taste to the soup. The excess liquid from cleaning the leeks should help prevent any burning.

Adding an acid like vinegar or lemon juice and incorporating fresh herbs can also help add flavor to a potato soup. While you may not need to implement all of these strategies, it's good to keep them in the back of your mind for when you realize your next pot of soup needs a flavor boost.

Potato Leek Soup Serving Suggestions

Jack and I often enjoy this potato and leek soup on its own, with good crusty bread, homemade focaccia, or dinner rolls on the side. If you're craving a larger meal, I recommend pairing it with a salad.

Should I cook potatoes before adding to soup? ›

There's no correct way but some methods provide difference outcomes. I normally dice my potatoes quite small, boil them on their own and add to the soup at the end. That way they are perfectly cooked. On the other hand you can add them with other vegetables and the potatoes will begin to crumble once they are cooked.

It turns out, then, that contrary to internet opinion, it is possible to redeem your potato leek soup if somehow it becomes gluey. Ladle some into a freezer bag, freeze it flat, thaw it, and pour off the water.

Season leeks with soy, maple, sesame oil, and mirin. Top with sliced garlic and a few knobs of butter around the outside of the pan. Add just enough stock to cover leeks halfway, bring to a boil and pop into over to roast until caramelized and tender when pierced with a knife.

Lastly, the most common substitute for leeks is the ultimate kitchen staple; onions. White and sweet onions are the best alternatives for leeks, due to their mild flavor.

It looks as though some of your potatoes might have got a bit scorched. Did you fry them off before adding the liquid? The colour from the browned potatoes could be what is turning it brown.

To thicken potato soup without creating lumps, you can use a roux made of equal parts butter and flour. Melt the butter in a separate pan, add the flour, and whisk until smooth. Slowly whisk the roux into the soup, and let it simmer until thickened.

Cornstarch is not the only thickening agent you can use. Other alternatives include flour, arrowroot powder, instant mashed potatoes, or even pureed vegetables like cauliflower or cooked oats. Each of these options will add thickness to your soup while imparting its own unique taste and texture.

Plant leeks into the bottom of a 5‐7” deep and wide trench. Space plants 4‐5” apart. Begin blanching as plants grow and thicken by piling soil or straw around the leeks inside the trench. This practice keeps the bottom of the leeks white and tender.

Ok, this may be a little obvious, but just adding water is going to make your soup go a little further. If you stick to a 50/50 ratio between water and whatever flavoured liquid you're using in your soup (be it tomatoes, a stock type, or a cream), you're unlikely to dilute it to the point of making it unpalatable.
