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.
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 hot almond milk drink to warm me up.
Some soup recipes to try are my Curried Summer Squash Soup recipe, Easy Vegan Tomato Soup with Tomato Paste, Vegan Curry Pumpkin Soup, Vegan Black Bean Soup recipe, and Creamy Sweet Potato and Rosemary Soup.
Other recipes to try are my Roasted Garlic Focaccia and my Vegan Mashed Cauliflower.

🔪 Instructions
Step 1: 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.
Step 2: Roast for 20-25 minutes, or until cauliflower is starting to brown. Roast garlic for another 15-20 minutes, or until tender. While cauliflower and garlic are roasting, soak cashews in water for at least an hour to soften them, or in hot water for 15 minutes. Drain water.
Step 3: In a pan, sauté onions in olive oil.
Step 4: Add cashews, cauliflower, garlic, onions, tamari, broth, and salt and pepper into a blender.
Step 5: Blend until creamy. Pour into a saucepan and simmer until heated.
❄️ Can I Freeze It?
- Make sure to let the soup cool completely before placing it 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 of the way full. Let out as much air as you can, and lay flat in the freezer.
- Don't forget to label your bag or container with the date, or if you prefer, the date it should be eaten. You can keep soup in the freezer for 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.
