Ingredients for the Best Roasted Cauliflower Soup

Alright, let’s talk ingredients! You know I’m all about using the *good* stuff. Here’s what you’ll need to make this roasted cauliflower soup a total knockout:

Essential Ingredients

Grab a big head of cauliflower (cut into florets, saves you time!), a red onion (chopped!), garlic (pressed or minced, your call!), good olive oil, veggie broth, butter (or olive oil for vegan!), lemon juice, nutmeg, and fresh parsley for garnish. Simple, right?

How to Make Roasted Cauliflower Soup: Step-by-Step Instructions

Okay, here’s where the magic happens! Don’t worry, it’s easier than you think. Just follow these steps, and you’ll be slurping up delicious roasted cauliflower soup in no time!

Roasting the Cauliflower for Maximum Flavor

First, preheat your oven to 425°F. This is key! While it’s heating, chop up that cauliflower into bite-sized florets. Toss them with olive oil and a sprinkle of salt. Spread them out on a baking sheet – don’t overcrowd! Roast for 25-35 minutes, until they’re tender and beautifully caramelized. You want those browned edges; that’s where the flavor is!

Building the Soup Base

While the cauliflower roasts, let’s get the soup base going. In a big pot (Dutch oven is perfect!), heat up some more olive oil. Add your chopped red onion and cook until it’s soft and translucent – about 5-7 minutes. Then, toss in the garlic and cook for just 30 seconds, until it’s fragrant. Careful, don’t burn it!

Simmering and Blending for Creaminess

Pour in the vegetable broth and give it a stir. Once the cauliflower is roasted, reserve a few of the prettiest florets for garnish (we eat with our eyes, people!). Add the rest of the roasted cauliflower to the pot. Bring the soup to a simmer, then reduce the heat and let it cook for about 20 minutes so the flavors can all meld together. Now, for the creamy part! Carefully transfer the soup to a blender (or use an immersion blender). Add the butter (or more olive oil) and blend until it’s super smooth. Be careful blending hot soup – it can splatter!

Seasoning and Garnishing Your Roasted Cauliflower Soup

Almost there! Add your lemon juice and nutmeg to the blended soup. Now, taste, taste, taste! Add more salt if needed. Seriously, don’t be shy with the salt; it really brings out the flavor. And a little extra lemon juice never hurt anyone! Ladle the soup into bowls, top with those reserved roasted cauliflower florets, and sprinkle with fresh parsley (or chives, or green onions – whatever you like!). Enjoy!

Tips for the Most Delicious Roasted Cauliflower Soup

Want to take your roasted cauliflower soup from “good” to “OMG this is amazing?!” Here are my secrets:

Achieving the Perfect Roast

Don’t be afraid to let that cauliflower get nice and brown! Those dark, caramelized edges are where all the flavor lives. And make sure you spread the florets out on the baking sheet; if they’re too crowded, they’ll steam instead of roast. Bleh!

Blending for Ultimate Creaminess

A high-powered blender is your best friend here. Blend that soup until it’s velvety smooth. If you’re using a regular blender, you might need to blend it in batches. And be super careful when blending hot liquids! Nobody wants a soup explosion.

Seasoning to Perfection

Taste, taste, TASTE! Seriously, this is so important. Salt is your friend, but don’t overdo it. Add a little at a time until the flavor really pops. And don’t forget the lemon juice! It brightens everything up and adds a little zing.

Roasted Cauliflower Soup Variations: Spice It Up!

Okay, so you’ve mastered the basic roasted cauliflower soup? Awesome! Now, let’s get a little crazy! This recipe is super versatile, so feel free to experiment and make it your own. Here are a few ideas to get you started:

Spicy Roasted Cauliflower Soup

Want to add a kick? Toss some red pepper flakes in with the cauliflower before roasting, or add a pinch of chili powder to the soup while it’s simmering. Ooh la la!

Herbed Roasted Cauliflower Soup

Fresh herbs are your friend! Try adding a sprig of thyme or rosemary to the baking sheet while the cauliflower roasts. Or, stir in some fresh sage at the end for a warm, earthy flavor. So good!

Cheesy Roasted Cauliflower Soup

Okay, this might not be vegan, but trust me, it’s delicious! Stir in a little grated Parmesan or sharp cheddar at the end for a cheesy, comforting twist. Yum!

Serving Suggestions for Your Roasted Cauliflower Soup

So you’ve got this amazing roasted cauliflower soup…now what? It’s fantastic on its own, but why not make it a whole *thing*? Here are a couple of my go-to pairings:

Bread and Salad Pairings

Seriously, a chunk of crusty bread is a MUST for dipping. And a simple green salad with a light vinaigrette? Perfection! It cuts through the richness of the soup. Mmm!

Protein Additions

Want to make it a heartier meal? Add some grilled chicken or chickpeas! They both add a little protein and make it super satisfying. You could even toss in some toasted nuts for extra crunch!

Storing and Reheating Your Roasted Cauliflower Soup

Leftover roasted cauliflower soup? Lucky you! It keeps great, so you can enjoy it again later. Here’s the lowdown on storing and reheating:

Refrigerator Storage

Just pop it in an airtight container and it’ll be happy in the fridge for about four days. Easy peasy!

Freezer Storage

Want to keep it longer? Freeze it! Let it cool completely, then pour it into freezer-safe containers (leave a little room for expansion!). It’ll last for a good couple of months. When you’re ready to eat, thaw it in the fridge overnight.

Reheating Instructions

You can reheat it on the stovetop over medium heat, stirring occasionally, until it’s heated through. Or, if you’re in a hurry, microwave it in a microwave-safe bowl. Just be sure to stir it halfway through so it heats evenly!

Roasted Cauliflower Soup: Frequently Asked Questions

Got questions about this amazing roasted cauliflower soup? I got answers! Here are a few things I get asked all the time:

Can I use frozen cauliflower for this roasted cauliflower soup recipe?

Okay, so fresh cauliflower is *always* best for roasting, trust me. But if you’re in a pinch, you *can* use frozen. Just make sure you thaw it completely and pat it dry before roasting. Otherwise, it’ll be kinda soggy. Still tasty, but not quite the same!

How can I make this roasted cauliflower soup vegan?

Easy peasy! Just swap the butter for olive oil. That’s it! The rest of the recipe is already vegan-friendly. So simple, right?

Can I make roasted cauliflower soup ahead of time?

Totally! This soup is actually even better the next day, after the flavors have had a chance to meld. Just store it in the fridge and reheat it when you’re ready to eat. Perfect for meal prepping!

What gives roasted cauliflower soup its creamy texture?

It’s all about the blending! Roasting the cauliflower first breaks down the fibers, so it blends up super smooth. Plus, using a high-powered blender really helps to get that velvety texture. No cream needed!

Description

Creamy and flavorful roasted cauliflower soup.


Ingredients

Scale
  • 1 large head cauliflower (about 2 pounds), cut into bite-size florets
  • 3 tablespoons extra-virgin olive oil, divided
  • Fine sea salt
  • 1 medium red onion, chopped
  • 2 cloves garlic, pressed or minced
  • 4 cups (32 ounces) vegetable broth
  • 2 tablespoons unsalted butter
  • 1 tablespoon fresh lemon juice, or more if needed
  • Scant ¼ teaspoon ground nutmeg
  • For garnish: 2 tablespoons finely chopped fresh flat-leaf parsley, chives and/or green onions

Instructions

  1. Preheat the oven to 425 degrees Fahrenheit. If desired, line a large, rimmed baking sheet with parchment paper for easy cleanup.
  2. On the baking sheet, toss the cauliflower with 2 tablespoons of the olive oil until lightly and evenly coated in oil. Arrange the cauliflower in a single layer and sprinkle lightly with salt. Bake until the cauliflower is tender and caramelized on the edges, 25 to 35 minutes, tossing halfway.
  3. Once the cauliflower is almost done, in a Dutch oven or soup pot, warm the remaining 1 tablespoon olive oil over medium heat until shimmering. Add the onion and ¼ teaspoon salt. Cook, stirring occasionally, until the onion is softened and turning translucent, 5 to 7 minutes.
  4. Add the garlic and cook, stirring constantly, until fragrant, about 30 seconds, then add the broth.
  5. Reserve 4 of the prettiest roasted cauliflower florets for garnish. Then transfer the remaining cauliflower to the pot. Increase the heat to medium-high and bring the mixture to a simmer, then reduce the heat as necessary to maintain a gentle simmer. Cook, stirring occasionally, for 20 minutes, to give the flavors time to meld.
  6. Once the soup is done cooking, remove the pot from the heat and let it cool for a few minutes. Then, carefully transfer the hot soup to a blender, working in batches if necessary. (Do not fill past the maximum fill line or the soup could overflow!)
  7. Add the butter and blend until smooth. Add the lemon juice and nutmeg and blend again. Add additional salt, to taste (I usually add another ¼ to ¾ teaspoon, depending on the broth). This soup tastes amazing once it’s properly salted! You can also a little more lemon juice, if it needs more zing. Blend again.
  8. Top individual bowls of soup with 1 roasted cauliflower floret and a sprinkle of chopped parsley, green onion and/or chives. This soup keeps well in the refrigerator, covered, for about four days, or for several months in the freezer.

Notes

  • Soup keeps well in the refrigerator, covered, for about four days.
  • Soup can be frozen for several months.
