Ingredients in paleo cauliflower soup

Raw cashews – when raw cashews are blended in a high-speed blender they mimic heavy cream. It's a great trick to reduce or eliminate dairy without sacrificing flavor. If you don't have a high-speed blender, use cashew butter instead.

Bacon – we like to use sugar and nitrate-free bacon.

Onion – we use a white onion for mild flavor, but you can use a yellow onion if that's what you have on hand.

Garlic – soup always tastes better with garlic!

Cauliflower – use a medium-sized cauliflower head. Since we're blending it, you can use the white part of the stem, too!

Bone broth – bone broth is incredibly healthy for you. We use our homemade chicken stock but you can use beef bone broth instead for a richer flavor.

Thyme, black pepper, and salt – to season the soup

How to make paleo cauliflower soup

This soup is a breeze to make in just over half an hour.

  1. Start by soaking the cashews in hot tap water. This will soften them so they'll blend easier.
  2. Next, cook the bacon until it's crispy.
  3. Once the bacon is crispy, saute the onion and garlic in some of the bacon oil.
  4. Now add the cauliflower, bone broth, and seasonings to the pot and let it simmer.
  5. When the cauliflower is nice and tender, work in batches to puree the soup with the soaked cashews and some of the crispy bacon in your blender or with an immersion blender. After you return the soup to the pot, taste it and add more salt if you'd like.
  6. To serve your soup, ladle it into bowls and top it with some crispy bacon and a sprinkle of chives.

Where to find paleo bacon?

The only problem with bacon is that it is often cured with nitrates and sugar. Most of us who lean towards a paleo lifestyle try to avoid those two things as much as possible.

And if you're doing a round of Whole30, they're definitely out.

Luckily, it is possible to find paleo/Whole30-compliant bacon. Well-stocked health food stores (like Whole Foods and Trader Joe's) will often carry some. You'll find it less often at your regular grocery store. Also, check local farms or your farmers' market!

Recipe FAQs

Do you use cashews in any of your other recipes?

Yes! One of our favorite tricks for making soups and sauces rich and creamy is blending cashews. You can also try our cashew coconut salmon curry and our dairy-free pork chops and mushroom soup. They've also made an appearance in a couple of the recipes in the Sugar Free Paleo Dinner Recipes cookbook.

How long does this paleo cauliflower soup last in the fridge?

If you store this soup in an air-tight container in your fridge it will last for 3-4 days.

Can I freeze paleo cauliflower soup?

Yes! This soup freezes very well. Freeze it in an airtight container like these Stasher bags. It will keep fresh tasting for at least 3 months.
