Roasted cauliflower and garlic make this soup rich and comforting. This easy Creamy Roasted Cauliflower and Garlic Soup is perfect for cold winter months!
Roasting cauliflower is my favorite way to prepare it, so making a Creamy Roasted Cauliflower and Garlic Soup was a no-brainer for me.
To add even more roasted goodness, I roasted a head of garlic. I could eat roasted garlic on toast daily.
Mixing roasted garlic with vegan mayo makes it even more indulgent. I like to add roasted garlic mayo to sandwiches, which I did in my Balsamic Roasted Vegetable Sandwich.
Soup is one of those meals that I eat year round, even in 100° weather! There is just something so comforting about a hot, creamy bowl of soup. What can I say, I love soup.
I am always cold, so it's not unusual for me to want a hot meal or drink to warm me up. Case in point; as I am writing this, I am wearing fingerless gloves and a scarf - my usual indoor attire during winter months.
Did you know that January is National soup month?
- Soak cashews in water for at least an hour to soften them. Slice ½" off the head of garlic. Place on tinfoil and drizzle olive on top.
- Put cauliflower florets on a parchment lined sheet pan. Drizzle olive oil on top. Roast 20-25 minutes, or until cauliflower is starting to brown.
- Roast garlic another 15-20 minutes, or until tender.
- In a pan, sauté onions in olive oil.
- Add cashews, cauliflower, garlic, onions, tamari, broth, and salt and pepper into a blender. Blend until creamy. Pour into pan and simmer until heated.
This soup will last up to 5 days in an airtight container in the fridge.
Can I Freeze It?
- Make sure to let the soup cool completely before placing in a freezer bag or air tight container.
- Liquids expand as they freeze, so don't fill containers or bags all the way full. For freezer safe containers, leave about an inch of space from the top. For freezer bags, fill about ¾ the way full. Let out as much air as you can, and lay flat in freezer.
- Don't forget to label your bag or container with the date, or if you prefer, the date it should be eaten by. You can keep soup in the freezer 4-6 months, but flavors in the freezer start to fade around 2 months.
- When you're ready to eat, let the soup thaw overnight in the fridge, then heat in a saucepan or microwave.

Allergies to cashews. What can I use instead?
Willow Moon says
You could try white beans, like cannellini beans or sunflower seeds. If you use sunflower seeds make sure to soak them like you would for the cashews.
This looks so yummy. I'll have to try it out!
