This thick, rich potato soup gets its depth-of-flavor from one of my favorite plant-based ingredients – miso paste! This umami-forward ingredient is coupled with roasted cauliflower, slow-cooked onions and garlic and herbs for a truly delicious vegan potato cauliflower soup!

What is the Best Potato for Potato Soup?

Let’s start at the beginning: what is the best potato for potato soup?

If you’re new to cooking, this might seem like a silly question. Not all potatoes are made alike though. Choosing the best potato for potato soup can make or break the end result, so let’s talk about the differences.

What is the Best Potato for Potato Soup: Russet Potatoes

Russet Potatoes

Russet potatoes have a thick skin and a light and fluffy texture when cooked. This dry, starchy consistency will work for this Vegan Potato Cauliflower Soup in a pinch, but it’s not my first choice. They’re best served baked, roasted or fried.

What is the Best Potato for Potato Soup: Red Potatoes

Red Potatoes

Red potatoes are often the star of potato salad recipes. They have a thin skin and stay firm when cooked. Like Russet potatoes, you can use them in this Vegan Potato Cauliflower Soup, but I prefer to eat them roasted, steamed or grilled.

What is the Best Potato for Potato Soup: White Potatoes

White Potatoes

These popular spuds have a consistency similar to red potatoes. They’re best pan-fried and served as a side for breakfast or as French fry side to your favorite plant-based burger.

What is the Best Potato for Potato Soup: Yukon Gold

Yukon Gold Potatoes

Yukon Gold potatoes are a member of the yellow potato family. They have a thin skin and, when cooked, have a rich buttery flavor and creamy texture. If you guessed they’re the key to this Vegan Potato Cauliflower Soup, you’d be right!

Should I Peel Potatoes for Potato Soup?

Whether or not you should peel potatoes for potato soup depends on the kind of potato you’re using. This Vegan Potato Cauliflower Soup recipe uses Yukon Gold potatoes, which have a thin skin. As such, I just wash them and dice them before adding them to the soup.

As an added bonus, much of a potato’s flavor and nutrition is found in the skins. So, including them as part of the final dish has benefits beyond saving time. Yukon Gold potatoes are high in fiber and potassium.

So there you go! No need to peel!

What is the Thickener in Potato Soup?

Potato soup is often thickened with cornstarch or started with a roux. Some recipes call for the addition of bread, but there’s no need to do that for this healthy cauliflower potato soup!

The Yukon Gold potatoes and an immersion blender do all of the work. All you need to do is cook the potatoes until they’re soft and then blend the soup until its creamy. 

What Goes Best with Potato Soup?

I really only need a crusty piece of bread as a side when I make this Vegan Potato Cauliflower Soup. It’s thick, rich consistency makes it an ideal candidate for a healthy dinner.

For additional flavor, I’ll sometimes make mushroom bacon to add as a topping. If you haven’t tried this plant-based bacon substitute, I think you might be surprised by how satisfying it is.

I use a combination of tamari and maple syrup to get that salty sweetness that bacon provides. Add a dash of smoked paprika and some safflower oil for a touch of that rich smokiness and this healthy cauliflower soup recipe is reminiscent of a baked-stuffed potato.

Ingredients
  

Mushroom Bacon

  • 10-12 cremini mushrooms washed and sliced
  • 1/4 cup tamari
  • 1 tbsp safflower oil or other heat-tolerant oil
  • 2 tbsp pure maple syrup
  • 1 tsp balsamic vinegar
  • 1/4 tsp smoked paprika

Vegan Potato Cauliflower Soup

  • 3 tbsp extra virgin olive oil divided
  • 1 yellow onion roughly chopped
  • 4 cloves garlic roughly chopped
  • 2 tsp salt
  • 1 head cauliflower washed and broken into florets
  • salt & pepper to taste
  • 4 lbs Yukon Gold potatoes cut into equal-sized pieces
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 1 quart low-sodium vegetable broth + water see Recipe Notes
  • 1/2 cup lukewarm water
  • 4 tbsp white or yellow miso paste
  • 2 tbsp nutritional yeast
  • 1 tbsp fresh lemon juice
  • salt & pepper to taste
  • 2 scallions washed and sliced as optional garnish

Instructions
 

  • Thinly slice the mushrooms.
  • Combine the tamari, maple syrup, balsamic vinegar and smoked paprika. Pour the marinade over the mushrooms and allow to marinate until the soup has finished simmering.
  • Drain the marinade and spread the mushrooms out on a baking sheet lined with parchment paper. See Recipe Notes. Bake the mushrooms at 425º for 15-20 minutes until the desired consistency is reached.
  • Toss the cauliflower in 1 tbsp olive oil and season with salt and pepper. Spread the cauliflower out on a baking sheet and roast a 425º until browned. About 20 minutes.
  • While the cauliflower is roasting, add the remaining 2 tbsp olive oil to a large stock pot. Heat on medium-low heat until shimmering. Add the onions and the salt. Slow cook the onions until they begin to brown. About 12-15 minutes.
  • Add the garlic, rosemary and thyme and continue to cook for 2-3 minutes until fragrant.
  • Add the vegetable broth, cauliflower and potatoes to the pot. Add water as necessary to cover the potatoes and potatoes.
  • Simmer until the potatoes are soft. Allow the soup to cool slightly, then blend until a smooth consistency is achieved. About 20 minutes.
  • Combine the warm water & miso paste in a glass bowl. Mix until the miso paste has dissolved. Add the nutritional yeast and lemon juice. Stir to combine and then add to the potato soup.
  • Season with salt and pepper, as desired, and garnish with green onions and mushroom bacon.

Notes

  • I add enough water to the pot to ensure that the potatoes are covered. This makes for a fairly thick soup. If a thinner consistency is desired, add more water.
  • Take care to spread the mushrooms out on the baking sheet. This will help to achieve a crispy bacon-like texture. If the mushrooms are crowded, they will steam instead of baking. I like to use parchment paper because the tamari-maple syrup marinade becomes sticky when cooked and it is hard to remove from a baking sheet.
