Celeriac Soup with Gruyere and Truffle Oil

This comforting celeriac soup is healthy so easy to make and surprisingly delicious. A great first course for a fancy dinner party or a light cozy main for guests watching their waistline.


I don’t think celeriac soup is one that many people make for themselves or their families. Its sometimes on the menu at higher end restaurants, but celeriac is an ingredient that is a little out of the ordinary for most people. I think its because people don’t realize how damn tasty it is! When you serve it to guests at your home, they might be a little apprehensive at first when you tell them its celeriac soup, but after the first bite, you will be a culinary star in their eyes. And you don’t even have to tell them how easy it was!

Celeriac soup works for so many different entertaining occasions. Its the perfect first course for a formal dinner party or a cozy and comforting main course for guests who prefer a lighter meal. Or for vegetarians, if you leave out the pancetta.

Can we talk about the truffle oil for a second please? There really is nothing like truffle oil to give a dish a little class. It just sounds decadent and elegant. You only need a tiny little bit. Just a few drops on each bowl of soup. It looks cool and it tastes even better. If you haven’t had truffle oil before, you really must. Its one of those ingredients that has the power to elevate something as simple as soup, or even french fries, to another culinary level. A great tool for anyone who is entertaining guests with a refined or adventurous palate.

When you buy truffle oil, look for one with only oil and truffles in the ingredient list.

Now, I know that gruyere and cream are not exactly what you would call healthy, however, these two ingredients are totally optional. This celeriac soup still tastes AMAZING without these two ingredients. It really does… Of course cheese and cream also taste amazing lol, but if I or my guests were concerned with the amount of calories we were eating, or being dairy free, I would leave the cheese and cream out and just serve this with sprinkle of pancetta or bacon (because you can’t totally deprive yourself, right?) and a handful of chopped chives.


This celeriac soup would be even better served with crunch homemade croutons! Those will be going in our soup next time for sure!

Celeriac Soup with Gruyere and Truffle Oil
Recipe Type: soup
  • 1 large onion, peeled and quartered
  • 2 large leeks, sliced in half and washed well
  • 3 cloves garlic, peeled
  • 4 stalks celery, washed and trimmed
  • 2 celeriac roots, peeled and cut into cubes
  • 4 or 5 sprigs of thyme
  • 3 tbsp olive oil
  • 1 tbsp salt
  • 1 tsp pepper
  • 6 cups chicken or vegetable broth
  • 2 cups shredded gruyere cheese (optional)
  • 1 cup heavy cream (optional)
  • salt and pepper to taste
  • 500 g cubed pancetta or bacon
  • chives and parmesan cheese for garnish
  • truffle oil to drizzle on top
  1. First, roast your veggies. Heat your oven to 350 degrees. Place the onion, leeks, garlic, celery, and celeriac on a large baking tray, drizzle with olive oil, sprinkle with salt and pepper, and lay your thyme sprigs on top all around. Roast in the oven till your veggies are very tender, browned on the edges, and smell amazing. About 30 mins or so.
  2. While your veggies are roasting, fry up the pancetta in a skillet on medium high heat till they are nice and browned and crispy. Remove from the pan into some paper towel to drain the fat.
  3. Remove the veggies from the oven and place in a blender with a cup or two of the chicken stock. Blend well until everything is smooth and creamy. You might need to add a bit more stock or do this in two batches depending on how big your blender is. You can also do this with an immersion blender in a big pot too.
  4. Add everything to a large pot and turn the heat to medium. Add the rest of the stock and bring it to a simmer to heat it through. Turn the heat down to low and add the cheese and heavy cream. Stir until all the cheese is melted. Season to taste with salt and pepper.
  5. Serve with pancetta, chives, and parmesan sprinkled on top. Drizzle a small amount of truffle oil to finish. About half a tsp per bowl or how every much you like.
