Homemade Cauliflower Soup

I’m in full soup mode over here for #JanuaryWhole30! Using my bone broths, veggies, and blender makes me a happy woman. So it should come as no surprise that this blended cauliflower bisque is speaking my love language!

This creamy roasted cauliflower soup has a deep, nutty flavor thanks to the baking process with a creamy consistency and all the healing powers of bone broth. This is the break we all need right now after the onslaught of holiday cookies and parties!

As a bonus, I’m throwing in some collagen powder (can’t stop, won’t stop!) and topping it off with a dollop of pesto and crispy bacon bits. These flavors come together like a winter miracle snow globe in your mouth. Yes, I’m that confident you will love this!

Key Ingredients

The beauty of this Roasted Cauliflower Soup is how simple it is to prepare, starting with just 9 ingredients:

• One medium head of cauliflower
• Melted coconut oil
• Sugar- and nitrate-free bacon
• One yellow onion
• Bone broth (I prefer homemade, but store-bought it fine.)
• Canned coconut cream
• Collagen peptide powder (I like Vital Proteins, but you can use whatever’s available.)
• Sea Salt
• Dairy-free pesto

Will I Taste the Coconut Milk in This Soup?

While I do use a bit of coconut cream in this, you will not taste it in the soup. I commonly get asked about that, but in small doses and when mixed with other ingredients, it’s really just used for the texture instead of dairy-based cream.

How To Make Cauliflower Soup

• Roast the Cauliflower: Preheat your oven to 400 degrees, and cut the head of cauliflower into small florets. Toss them in melted coconut oil, and spread evenly on a parchment paper-lined baking sheet. Roast for 30 minutes, tossing half-way in between. 
• Cook the Bacon: In a large bottom-heavy pan or Dutch oven, cook the slices of bacon over medium-heat until crispy and all the fat has been rendered. Set aside on a paper towel-lined plate to cool before crumbling.
• Sauté the Veggies: Don’t toss that bacon fat! Use it to cook the onions. Then, once those are translucent, add the roasted cauliflower, and stir to coat. Add bone broth over top and turn the heat high to bring to a boil. Once boiling, reduce the heat to low, cover, and let simmer for about 15 minutes, or until the cauliflower is very soft.  
• Blend It Up: Once the soup is cooked, turn off the heat and transfer to a high-speed blender. Add coconut cream, collagen, and another pinch of sea salt to taste. Blend on high for 30 seconds or so until everything is creamy and well combined.
• Serve: Ladle into bowls, serve, garnish with bacon and pesto, and enjoy!

Serving Variations

In addition to the dairy-free pesto and crumbled bacon, you could also garnish each bowl of this Roasted Cauliflower Soup with some toasted or raw seeds like pepitas, sesame seeds, or sunflower seeds. Roasted chickpeas would also be divine!

This soup is delicious on its own, but you could serve it alongside my Soda Bread Biscuits, Kale Apple Salad, or AIP Salmon Cakes to complete the meal.
