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 is my leek and potato soup bland? ›

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.

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? ›

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 you prepare turnips for soup? ›

To dice a turnip for soup, start by peeling it and cutting off the ends. Then, slice the turnip widthwise into rounds. Stack a few rounds on top of each other and cut them into sticks. Finally, cut the sticks into small, uniform cubes.

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.

Why does my leek and potato soup taste bitter? ›

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.

Why do you soak leeks in water? ›

Soak the stalks in a bowl of cold water for 10 minutes or so, then rinse under cold running water in the sink. The long soak allows the water to penetrate the leek's many layers, clearing out all the bits of debris. Once your veg is all cleaned up and dirt-free, it's time to get cookin'.

How does Gordon Ramsay cook leeks? ›

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.

Why don't you use the green part of leeks? ›

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.

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.

What is the best thickening agent for potato soup? ›

Cornstarch is a great option as it is a natural thickening agent, but you'll want to be careful about how much you use. Start with 1 tablespoon of cornstarch whisked together with cold water to create a slurry. Then, gradually add the slurry to the soup, letting it boil for one to two minutes before adding more.

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.

What makes turnips taste better? ›

How do you get the bitterness out of turnips? Smaller turnips tend to be sweeter and less bitter, so start by selecting fresh, small, tender turnips and peeling them. Adding a little sugar to your turnips after cooking can also help to counteract any bitterness.

Why put baking soda in turnips? ›

One turnip website from the United Kingdom notes that if you boil them, add a little sugar to tame the scent and add baking soda to reduce bitterness.

Should turnips be peeled for soup? ›

It's not essential to peel turnips before cooking. If this skin appears to be thin enough you can leave it on and cook as is. However if the skin feels thick and leathery, you can peel it off with a sharp knife or vegetable peeler. Both the roots and leaves, also known as turnip greens, are safe to eat.

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 make potato soup less bland? ›

Wine, cider, beer, or juice may be used, and each adds its own flavor while also helping to release the tasty brown bits from the bottom of the pan. Adding an acid like vinegar or lemon juice and incorporating fresh herbs can also help add flavor to a potato soup.

How do I add flavor to bland beef soup? ›

Beef stock on its own should be extremely rich; how did you make it? If the soup is already made and you just want to deepen the flavour, try a shake of a pre-made sauce such as Worcestershire, brown sauce, barbecue sauce, soy or even kecap manis etc.

How do you fix bland bean soup? ›

I would start with this, but some other ideas: saute or roast the vegetables rather than adding to the soup while still raw (if you are currently adding them raw); add a bit of Asian fish sauce/mushroom bouillon/msg to add some additional umami; beef up your stock by simmering some chicken feet/chicken backs/pork neck ...
