This six-ingredient cauliflower soup is everything you want in a cozy dinner: ultra-smooth (it’s surprisingly creamy for being dairy-free) and un-put-down-able thanks to one little trick—we roast the cauliflower first for big, bold flavor.

This, my friend, is the easy cauliflower soup recipe you’ll come back to all soup season long. It’s rich without a drop of dairy and basically foolproof thanks to roasting the veggies. All you need is a sheet pan, a blender, and a little hands-off oven time.

You’ll Have This On Repeat

  • Impressively Easy: This creamy blended soup looks and tastes gourmet, but it’s secretly beginner-friendly.
  • Customizable Toppings: Swirl in coconut cream, drizzle with chili oil, or (our personal fave) pile on a handful of our homemade crispy chickpeas!
  • Freezer-Friendly: Make a double batch and stash some away for busy weeks.

Key Ingredients

We kept things fuss-free for this blender soup with roasted vegetables (I mean, how can you argue with six pantry-friendly ingredients?). Jump down to the recipe card for exact measurements.

  • Cauliflower: Roasting brings out its nutty, caramelized side and gives the soup that rich, savory depth without needing cream.
  • Aromatics: Every great soup starts with onion (yellow or white) and fresh garlic (which we roast for a deep flavor).
  • Vegetable Broth:Feel free to use store-bought or prep your own homemade vegetable broth!

Floret Size Matters

Try to keep your cauliflower florets roughly the same size so they roast evenly. If they’re too tiny, they’ll burn too quickly, but if they’re too chunky, they’ll just steam instead of getting those golden, crispy edges we’re after.

Leave The Garlic Skins On

Don’t worry about peeling your garlic before roasting. Leaving the skins on keeps the cloves from burning and helps them get all soft and caramelized on the inside. Once they’re out of the oven, just give them a little squeeze!

Instructions 

  • Roast: Preheat oven to 400°F (204°C). Cut 1 large head cauliflower into large florets and roughly chop 1 medium yellow onion into large pieces. Transfer cauliflower, onion, and 4 cloves garlic (skin still on) onto a baking sheet. Drizzle everything with ¼ cup olive oil and toss to coat.
    Roast for 25 to 30 minutes, or until cauliflower is charred and fork-tender.

  • Chickpeas (Optional): If making the Crispy Chickpeas, toss 1 15-oz can chickpeas (drained and pat dry) with 1 Tbsp olive oil. Spread onto a separate baking sheet and bake for 20 minutes, or until crispy. While still hot, toss chickpeas with 1 tsp smoked paprika, ½ tsp cumin, and ¼ tsp salt.
  • Blend: When cauliflower is tender, transfer cauliflower, onion, and garlic cloves (skin removed) to a blender. Add 3 to 4 cups warm vegetable broth (start with less and add more as needed) and ½ tsp salt.
    Blend with the lid ajar (never tightly seal hot liquids while blending) until smooth and creamy, about 1 to 2 minutes.

  • Serve warm, topping each serving bowls with the crispy chickpeas or simply shredded cheddar cheese and ground black pepper (and some crusty bread!).

Notes

Can I use frozen cauliflower? Yes! Frozen works in a pinch. No need to thaw—just roast it straight from frozen. The edges won’t caramelize quite as much, but the flavor is still delish.
Do I have to roast the cauliflower first? Yes, yes, a thousand times yes. Roasting brings out that sweet, nutty, caramelized flavor that makes this soup magic.
Is this soup meal-prep friendly? Yes! It lasts up to 4-5 days in the fridge and reheats beautifully. (Bonus: the flavors get even better the next day.)
Storage: Let it cool completely, then store it in an airtight container or freezer bag. Thaw overnight in the fridge, then reheat on the stove with a splash of extra broth if needed.

    This soup turned out NOTHING like the pictures. It is clumpy with visibly small portions of cauliflower. There’s no way the soup pictured was made from the ingredients listed. Terrible of you to waste people’s time, money and efforts.

    1. Sarah Bond says:

      Hi there! It sounds like you just needed to blend it for longer. We’ve made this soup dozens of times across our team and it always comes out creamy. I hope you’ll give it another go!

    Super easy and delicious!!! I wonder if I can do the same with any other vegetables?

    1. Sarah Bond says:

      Cauliflower is a bit unique in how smoothly it can blend up, but many vegetables can be turned into creamy soups! Especially if you have high powered blender!

  8. Genah says:

    Hello!
    Can’t wait to try this next week! One question, should the chickpeas be rinsed? This is the first recipe I’ve seen where they aren’t so just wanted to make sure. Thank you!

    1. Sarah Bond says:

      You don’t have to! Just be sure to dry them well 🙂
