Why This Soup Is So Good

One of my favorite things about this recipe is that it has nutritional yeast. If you love the flavor of nutritional yeast as much as I do, check out these 20 Recipes Using Nutritional Yeast.

The key to this recipe? Roasting the vegetables before adding them to the soup.

Roasting veggies brings out the ingredient’s natural sweetness. I snuck in a few more servings of vegetables on top of the cauliflower for a variety of nutrients. Each vegetable provides your body nourishment.

The fact that it’s pureed helps hide the veggies. So, if you or someone in your family is not generally a fan, then they won’t know the wiser. You cannot taste anything specific, so it’s the perfect way to add in more nutrition to your day.

Why I Love Cauliflower

In the 30 Days to a Healthier You challenge, I mentioned that cauliflower is the best sneaky veggie out there.

You can add cauliflower to soups, smoothies, stir-fries, even cake! It blends in with most dishes undetected.

Here are a few health benefits of cauliflower:

• High in B vitamins
• A great source of fiber
• High in vitamin C (a powerful antioxidant)
• Easy to add to your recipes and meals

Ingredients

For the roasted veggies, you’ll need:

• Avocado oil
• Russet potatoes (peeled and quartered)
• Baby carrots
• Cauliflower (broken into florets)
• Salt
• Pepper

For the soup, you’ll need:

• Avocado oil
• Onion (diced)
• Celery (diced)
• Crushed garlic
• Roasted veggies (listed above)
• Vegetable stock
• Nutritional yeast
• Salt
• Pepper
• Fresh thyme (can use dried in a pinch)
• Dijon mustard

Equipment

The key to this pureed roasted cauliflower soup recipe is having something to make it soup. You can get an inexpensive immersion blender anywhere (I linked one below). I couldn’t find mine (well, I had the baby proof locks on the cupboards and couldn’t be bothered to undo the death latches) so I used my Vitamix.

If you’re using a blender, ladle it into the jug (do not pour, you could burn yourself).

Do this in batches, transfer some to the blender, puree, then pour back into the pot. Continue this until you have the consistency you want.

Here are the supplies I used:

• Sheet pan
• Large stockpot
• Immersion Blender or a heavy-duty blender (like this one).

How To Make It

Sometimes the best recipes are the simplest ones. I loved making this soup because it was so easy and yielded a ton of flavor with minimal, wholesome ingredients.

All you do is roast veggies, sauté celery and onions, then simmer everything in a vegetable stock. Blend in a blender, and you’re done.

Serve with my favorite gluten-free biscuits to make it a more filling meal!

How To Make It in the InstantPot and Slow Cooker

I love soups because you can make them in a bunch of different ways to best suit your routine. I made this on the stovetop with a blender, but you could also make it in the InstantPot or slow cooker!

• To make this vegan roasted cauliflower soup in the Instant Pot, simply add your roasted veggies to the insert with the vegetable stock and cook on high pressure for 10 minutes. Set to naturally release, then blend with an immersion blender or ladle into a stand blender before serving.
• Or make this in the crock pot by adding the roasted veggies and vegetable stock to the insert, and then cooking on low for 4 hours or high for 2. This is a great way to keep it warm all day before serving.

Randa’s tip: It may sound odd but add a tablespoon of dijon mustard to the soup before serving. It adds an extra oomph (professional term) that gives the soup that “secret” something.
