A simple French soup that works well regardless of which vegetable gets the emphasis.

This is a simple French soup. If you want to vary the proportions of vegetables you can; it works well whether you emphasize the turnips, as I do here, the leeks or the potatoes. Turnips have a slightly bitter edge, and tarragon makes a lovely sweet garnish. Chives would also work.

Turnip, Leek and Potato Soup Recipe (2)

Preparation

  1. Step

    1

    Heat the olive oil in a large, heavy soup pot over medium heat and add the onion, leeks and a pinch of salt. Cook, stirring, until tender, about 5 minutes. Add the garlic and cook, stirring, until fragrant, 30 seconds to a minute. Add the turnips, potatoes, water or stock, salt to taste, and the bouquet garni. Bring to a boil, reduce the heat, cover and simmer 45 minutes, or until the vegetables are very tender and the soup is fragrant. Remove and discard the bouquet garni.

  2. Step

    2

    Blend the soup in batches in a blender (cover the top with a towel and hold it down to avoid hot splashes), or through a food mill fitted with the fine blade. The soup should be very smooth. Strain if desired. Return to the pot. Stir and taste. Adjust salt, add freshly ground pepper, and heat through. Serve in small bowls or espresso cups, garnished with chopped fresh tarragon and/or chives.

Tip

  • Advance preparation: You can make this a day or two ahead and reheat. The soup can be frozen, but you will need to blend it again when you thaw it.

Cooking Notes

Sara

This was really good! I used mostly broth with some water to fill it out, and I was pretty generous with the thyme. I also changed the ratios a bit according to what I had on hand (more leeks and potatoes, fewer turnips). It had a lovely consistency (I used a food processor to blend) and a ton of flavor. We garnished with more parsley.

Pizza Quixote

I've made this type of soup often, and you are generally rewarded by experimenting with root vegetables (parsnips, carrots, turnips, rutabaga, taro, etc) as well as garden herbs, fresh or dry (sage, parsley). If you want it creamy without a lot of added fat, adding a can of evaporated whole milk is a nice twist.

sledwell

Not bad, I added chicken stock and sherry (as someone else suggested) - it added depth. Skipped creme fraiche.

Kristin

Gosh; really expected more from this recipe. Bland, unappetizing color, needed a ton of doctoring (shredded cheese, fried lardons, chopped herbs) to make palatable. Wouldn’t make again.

SweetDisaster

Add extra salt and rosemary for flavoring. Add some roasted chicken to make a complete dish.

Lily

This is a lovely soup, with delicate flavors, perfect for winter. I will definitely make again whenever I have turnips.

wwicks

Just okay. I probably won't make it again.This is fairly bland when made and served as-written. It benefits from a health dose of salt and garlic powder. I also doctored it up with some Penzey's Justice blend, and that helped some. I think adding a few hearty glugs of cream would also help.

Energy Guy

Yes, as written here, it comes out a little bland. I made it more to my taste by adding 1 tsp thyme and 1 tsp tarragon (in addition to the tarragon used as a garnish). I used 4 cloves garlic instead of 2. I also included the first 2" of the dark green of the leeks. I'm not much on turnips, so I substituted parsnips.

Cynthia

Substituted daikon for the turnips as what I had available. Threw in a couple of brusels sprouts. Not very flavorful so went to one of my favorite recipes, Saxe-Coburg Soup, a brussels sprouts soup in Great British Cooking by Jane Garmey, and added cream and sherry at the end.

atl mom

No flavor at all. Will not make again

Mary

I made this and it was delicious! I only used fresh thyme and it was delicious. FWIW I blended the soup and tried some blended and some before I blended - and I ended up liking the non-blended version better. Here's the nutrition label for this exact recipe:

David T

Used a tablespoon of herbs de Provence, a tablespoon of dried thyme & a bay leaf because I didn’t have fresh herbs on hand. Turned out very well. Will definitely make again.

nancy ogden

no flavor! help!

DNcgo

Adding 1 tbs. ground turmeric to the softened onion/leek mixture adds a punch to both flavor and color.

Cindy C

Instead of the full 2 lbs of turnips, I used 1-1/2 lbs. of turnips, a small potato and 1/2 head of cauliflower. I also added 1/4+ tsp of tarragon and left the bay leaf, thyme and parsley intact instead of removing them.Additionally, I added 1/2 TBLS. of balsamic vinegar.As a garnish I added some sour cream when served.Excellent soup! If I didn't know better I'd swear that it was a cream of turnip soup.

Cindy C

I made this soup again using the recipe above but then I realized I also added 3/4 tsp. Ethopian Berbere spice which added much needed flavor.

Pizza Quixote

I've made this type of soup often, and you are generally rewarded by experimenting with root vegetables (parsnips, carrots, turnips, rutabaga, taro, etc) as well as garden herbs, fresh or dry (sage, parsley). If you want it creamy without a lot of added fat, adding a can of evaporated whole milk is a nice twist.

Eltee

Brilliant recipe that introduced me to the world of soups. If followed word by word with some help from YouTube on how to clean and pare veggies etc , it yields beautiful results. Ive seen the potato needs to be really small as it affects the taste of the soup.

FAQs

Why does my leek and potato soup taste 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.

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.

How to stop leek and potato soup from going gloopy? ›

Sear or roast your potatoes to prevent gummy soup

While you can certainly make potato soup by just chucking potato chunks into a pot of boiling water and going from there, many recipes recommend that you cook your spuds beforehand to maximize your dish's flavor.

Why is my potato leek soup gummy? ›

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.

How do I increase the depth of flavor in soup? ›

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.

When to add cream to soup? ›

If you started the soup with broth, stock or water, I would wait until the end to add the cream. You can warm the cream, or “temper” it, which is what I do. Take about half a cup of the hot broth and slowly add your cream to that, stirring constantly.

Why has my leek and potato soup gone brown? ›

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.

Why does my potato soup have no flavor? ›

Perhaps the simplest approach is to flavor your soup with salt throughout the cooking process. Instead of waiting until the end of cooking to realize your soup lacks taste, you can add a bit of salt during each phase of cooking. Doing so will help bring out the flavors of each of the ingredients.

What is the best thickening agent for potato soup? ›

Cornstarch. Cornstarch is a very effective thickener, and a little bit can go a long way.

How do you make potato and leek soup less salty? ›

In addition to potatoes, you can use other starchy vegetables like carrots or parsnips to absorb excess salt. Dairy products like milk, cream, yogurt, or sour cream can help balance out the saltiness of a soup or stew.

Why is my leek soup stringy? ›

Now, pay attention: Simmer your leeks gently in well-salted water. Don't let them boil and don't let them go too long. They should be tender and silky, not mushy or stringy. Conversely, if not cooked enough, they'll be unpleasantly chewy.

How do you fix gluey potato leek soup? ›

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.

How do you make potato soup not gluey? ›

This starch will bond with the broth, causing the body of the soup to become slimy. To guard against this, it is best to mash the potatoes into the soup with a potato masher or a large fork, or to run the soup solids through a food mill to crush them.

How do I add flavor to bland potato soup? ›

Cheese: I recommend a good sharp cheddar cheese here for maximum flavor. Greek yogurt or sour cream: To make the soup extra-creamy. Salt and pepper: Add in as much as you need at the end to season your soup well.

How do you fix bland potato soup? ›

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.

Why does my soup taste flavorless? ›

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl. Start with the basics. Ensure you've added enough salt and black pepper.

Why does my soup taste bland? ›

If your broth tastes thin and bland, you may want to cook and let it evaporate for longer. That helps concentrate its flavors and gives you a better-tasting soup broth. Be sure to remove the lid to let the steam escape.
