Should leeks be sauteed before adding to soup? ›

Sautéing leeks before adding them to the soup can enhance their flavor and bring out their sweetness. Heat some oil or butter in a pan, then add the sliced leeks. Cook them over medium heat until they become soft and slightly caramelized. This step adds depth of flavor to your soup.

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.

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.

In the US, England, and most other English-speaking areas, the dark green portion of the leek is fibrous and often has a "soapy" flavor which detracts from the flavor of the dish. It's not a good idea even to use those for vegetable stock, as the overall flavor is unpleasant.

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.

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.

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.

If not, some mild acidity will help, adding a squeeze of lemon juice may do it for you. Bitterness is best counteracted by salt, so give it a good seasoning. You might also try adding a little mild vinegar like white wine or cider vinegar.

Some of our favorites are Dried Shallots, Dehydrated Red Bell Pepper, Dehydrated Green Bell Pepper, Tomato Flakes, Minced Onion and Roasted Garlic Flakes. Or, add a bay leaf to your recipe. The bay leaf will give the soup a little something extra without overwhelming the dish.

How do you perk up bland soup? ›

Perk up a Bland Soup With Simple Pantry Staples

Add a splash of vinegar (any kind!), or a squeeze of citrus. Chances are, you could use a little more salt. Go ahead—it's ok. Salt perks up flat flavors and helps balance out bitter-tasting ingredients.

You could add red pepper chili flakes, cayenne, Herbs de Provence or curry powder for more flavors. The caramelized onions add a lot of depth to the soup but you could also add in tomato paste or even miso or soy sauce.

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.

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.

First, slice the leeks in half lengthwise. Then, chop off the stringy roots and dark green leaves. You won't use the tough tops in most leek recipes, but still, don't toss them! They add delicious oniony flavor to homemade stock.

Place the leeks in a stockpot with the wine, thyme, peppercorns, salt and 7 cups of water. Bring the liquid to a boil over high heat, reduce the heat and simmer, partially covered, for 25 minutes. Remove from the heat and let the broth stand 10 minutes.
