Ingredients You’ll Need

Potatoes, fennel and onion are roasted to perfection and pureed with almond milk until thick and creamy smooth for a sensational soup that’s worth repeating!

Here is everything you need:

  • Fennel – The fennel adds a touch of sweetness with notes of anise/licorice and works well with the potatoes. If you’ve never cut fennel, here’s a guide: How To Cut Fennel
  • Potatoes – Use waxy potatoes – red, white or gold. I used gold potatoes here.
  • Onion – Any color onion will do.
  • Unsweetened Non-Dairy Milk – Use your favorite plain plant milk. I’ve been using cashew milk lately since it has a very neutral flavor.
  • Olive Oil – Use your favorite neutral flavored oil. A garlic oil would be nice too.
  • Vegetable Paste – I used 1/2 teaspoon of Better Than Bouillon Vegetable Base (affiliate link) with the liquids called for in this recipe. It adds lots of flavor without too much sodium and the jar lasts a long time!
  • Salt & Pepper – My favorite salt is pink mineral salt (affiliate link) which naturally contains essential minerals and trace elements the body needs. Season to taste with your favorite salt and pepper.

How To Make Roasted Fennel & Potato Soup

This fennel & potato soup recipe is so easy to make and only requires a few simple steps.

  • Prep the fennel, onion and potatoes. I peeled my potatoes to ensure my soup would be velvety, but feel free to leave the skin on. You may prefer to leave yours a little chunky. There is no wrong way!
  • Place the veggies on a baking sheet, add a little oil and toss, sprinkle with salt and pepper (shown above) and bake at 425 degrees for 35 – 40 minutes, until potatoes are fork tender.

  • Once vegetables are roasted, add them with your liquids and blend (shown above). Both an immersion blender or regular blender work well. For ultra creamy, I find a stand up blender works the best.
  • Finish by warming the soup on the stove.

Now your home will smell wonderful, and your taste buds and tummy will be happy!

How Long Will Leftovers Keep

Leftovers can be stored in the refrigerator for up to 5 – 6 days in an airtight container. It’s also freezer friendly and can be stored in the freezer for up to 3 months. Defrost the soup in the refrigerator overnight and reheat on the stovetop over medium heat until warmed through.

The smaller you chop the vegetables the quicker they will cook and vice versa.

RECOMMENDED EQUIPMENT: For roasting the veggies I switch between my Silpat or these parchment liners for lining this rimmed baking sheet (affiliate links). And for pureeing the soup I use this immersion blender. For more of my favorite cooking tools, shop my kitchen essentials!
