    Easy Leek & Potato Soup with Celeriac

    This Easy Leek & Potato Soup with Celeriac is quick & easy to make, creamy and super comforting yet not heavy at all. Delicious twist on an old classic!

    Bowl of leek & potato soup with bread, butter and chives.

    Leek & potato soup must be one of the most popular soups out there. It is also one of the easiest and most comforting soups to prepare and relies on the most humble of vegetables.

    I love soup for lunch throughout the year but once the weather gets that bit colder, that's when this particular recipe comes out. I must say I make it a lot!

    As much as I love simple leek & potato, very often I tend to add a little something extra to simply increase my veggie quota. This version including humble celeriac root is now by far my favourite one. I urge you to try it, unless celeriac is not your thing then simply leave it out.

    Few simple tips when making Easy Leek & Potato Soup with Celeriac

    Don't be to hung up on the quantity of veg. I suggested 2 medium leeks and potatoes, no need to use scales. If your veg is slightly larger and you might need a bit more liquid, go for it. Add splash more of stock/water, adjust seasoning and I'm sure your soup will be lovely. Soup making is not baking (pardon unintentional rhyme here), you don't need to be super precise to get wonderful results. I encourage you to go for it and make this simple leek & potato soup (with or without celeriac) your own.

    I've suggested the use of onion in my recipe although I must say I don't always include it as leeks carry very similar flavour. Feel free to use it or leave it.

    How to prepare leeks?

    Leeks can be a bit of a pain due to all the grit that hides in between all the layers. The best way to sort them out is to get rid of very top, dark green, woody part. Make sure you leave a bit of green though (closer to white part). Once you’ve done that, cut your leeks in half (lengthwise) and gently run them under cold tap gently separating the layers and getting rid of all the grit. Make sure the leek stays intact though (it will be easier to slice). Once clean, go ahead and slice each half nice and thin.

    Storing and serving suggestions

    I like to serve this lovely soup very simply with sprinkle of chopped chives and a generous slice of toasted and buttered sourdough or my Irish Soda Bread or this delicious Easy Wholemeal Bread. Sometimes if I feel the need to indulge I might add an extra swirl of cream or creme fraiche on top of my portion or perhaps some pan fried and chopped bacon. Also nice with homemade croutons or roasted pumpkin seeds sprinkled on top. My Vegetarian Sausage Rolls  and new favourite Vegan Cheese Scones also make delicious accompaniment!

    Once cooked, cool the soup promptly (especially if it contains creme fraiche or cream) and store in the fridge for up to 3 days. This soup also freezes brilliantly so make a large batch and freeze your leftovers for up to 3 months.

    Can this soup be adapted for vegan diet?

    Of course! This soup as per recipe below is veggie but not vegan, however, it can be easily adapted. Simply substitute dairy creme fraiche or double cream with a good splash of plant based milk and butter for vegetable oil of your choice. I like to use cold pressed rapeseed oil*.

    How to make Easy Leek & Potato Soup with Celeriac

    • Prepare your potatoes and celeriac (if using) by peeling them and cutting into rough chunks. Do the same with onions (if using).
    • Prepare the leeks by discarding the very top, dark green part., halving and cleaning them thoroughly, getting rid of all the grit. Slice thinly.
    • Melt butter in a large pan. Add prepared leeks and onion (if using) and cook until softened but not coloured (about 5 min). Make sure you keep and eye on it stirring it from time to time to prevent it from burning.
    • Add potatoes and celeriac (if using) and continue cooking for another 2-3 min.
    • Add stock, bit of salt and pepper and cover.
    • Simmer until all the veg, especially celeriac (which takes the longest) is tender (approximately 20-25min).
    • Take the soup off the heat and puree to desired consistency using hand/immersion blender. I like it really smooth and silky but you may want some texture to it.
    • Add creme fraiche, adjust seasoning and quickly blend again.
    • Serve sprinkled with chopped chives and some croutons.
    • Enjoy!

      Look forward to making this soup today for my family. Just wondering if adding garlic would be a good idea or not?

      Leek and Tattie soup is a firm favourite with my kids in this house. Now matter how big a pan I make they eat it almost everyday till its gone! I do love the addition of celeriac as I always seem to roast part of the head then there's always a small bit left - I'll make sure I add it next time:-) Thanks for sharing with #cookblogshare

      This looks delicious! But FYI, your instructions mention celeriac once and never says when to include the leeks. I assume the leeks come first and the potatoes and celeriac second, but it seems like something you may want to amend!

        Hi Francesca! You are absolutely right. First celeriac in the instructions was supposed to be leeks, all amended now! πŸ™‚ I have read this recipe so many times and have never tweaked so thanks for pointing it out! Glad you like the recipe πŸ™‚

      I only tried celeriac for the first time earlier this year, and it was quite nice. I can imagine that it adds a lovely depth of flavour to the classic leek and potato combo. Your soup looks so inviting x

      Love leek and potato soup and I'm pretty sure I'd like your celeriac addition. I haven't had celeriac in far too long, but I do like it. I find it really hard to post soup recipes as most of my soups are an ad hoc melange of whatever I happen to have to hand.

      I think adding the celeriac is a great idea then again I would as I love celeriac! I do like soups that use up the bits and pieces in the fridge a great way to avoid food waste.

      Just to let you know I will be guest hosting the #CookBlogShare linky this week over at Recipes Made Easy and I would love it if you pop over and linky up another recipe.

      Oooh yum...I love Leek and Potato Soup, but I've never thought to add celeriac to it before (which I also love), I will have to try that next time I make it. It's funny you saying about celeriac having a really distinct taste...I think it does too, but I somehow managed to completely fool my father in law and two children once when I made celeriac mash - they all thought it was regular mashed potatoes!?! Hilarious! Thanks for linking your lovely soup up to #CookBlogShare and Happy Easter!! Eb x

      I love leek and potato soups. They are just so creamy before you even add any extra cream and I love the sound of the celeriac in this one. I am definitely a celeriac fan and it must go so well with the leeks and potato. Thank you for sharing with #CookOnceEatTwice!
