Can You Vary Roasted Cauliflower Soup Recipe With Other Ingredients?

The Roasted Cauliflower Soup recipe can be adjusted to cater to different dietary needs:

  • Vegan: Substitute the butter with olive oil or vegan butter. Use vegetable broth instead of chicken broth. Replace milk with non-dairy milk like almond or coconut milk.
  • Vegetarian: Replace the chicken broth with vegetable broth.
  • Gluten-Free: Replace the all-purpose flour with a gluten-free alternative like cornstarch or a gluten-free flour blend.
  • Paleo: Replace the butter with ghee, the all-purpose flour with arrowroot powder, and the milk with almond milk or coconut milk.
  • Keto: Leave out the flour entirely or replace it with a keto-friendly thickener like xanthan gum. Use a low-carb milk alternative like almond milk.
  • Whole30: Substitute the butter with ghee. Replace flour with arrowroot powder and use Whole30-compliant chicken broth and non-dairy milk like almond or coconut milk.

Recipe Directions

  • Start by preheating your oven to 450 degrees F (230 degrees C).
  • Place your cauliflower florets into a small roasting pan. Drizzle them with the flavored olive oil.
  • Season your cauliflower with nutmeg, garlic powder, salt, and pepper. Toss everything together until the cauliflower is well coated in oil and seasonings.
  • Roast the cauliflower in your preheated oven. Make sure to give the cauliflower a good stir every 10 minutes.
  • Continue roasting until the cauliflower is golden brown and tender. This should take between 30 to 40 minutes. Once done, remove the pan from the oven and set it aside.
  • While the cauliflower is roasting, you can prepare your soup base. Melt the butter in a large saucepan over medium heat.
  • Once the butter has melted, add your finely chopped onion. Cook and stir the onion until it turns lightly golden brown. This should take about 10 minutes.
  • Sprinkle your flour over the cooked onions. Stir everything together until the onions are coated in the flour.
  • Slowly pour your chicken broth and milk into the saucepan. Use a wire whisk to mix everything together, ensuring all the flour is dissolved.
  • Bring your soup to a boil while stirring continuously. As soon as it thickens, reduce the heat to low.
  • Stir in your dry sherry and the roasted cauliflower you set aside earlier.
  • If you want a thicker consistency, you can blend half of the soup until smooth and then recombine it with the rest of the soup.
  • Your Roasted Cauliflower Soup is now ready to serve. Enjoy it while it’s hot. For an additional touch, garnish with your favorite herbs or a sprinkle of cheese.

Variations, Add-Ons, And Toppings


  • Spiced Version: Add a teaspoon each of cumin and coriander for a Middle Eastern twist.
  • Curry Cauliflower Soup: Add a tablespoon of curry powder before roasting the cauliflower for an Indian-inspired flavor.
  • Cheesy Cauliflower Soup: Stir in a cup of grated cheddar or Parmesan cheese until it melts for a cheesy variation.


  • Protein: Add shredded chicken or cooked, diced bacon for extra protein.
  • Vegetables: Add other roasted vegetables like carrots or sweet potatoes for added nutrition and flavor.

  • Chili Flakes: Sprinkle some chili flakes or drizzle chili oil for a spicy kick.

Scaling The Recipe

Scaling a recipe, like the Roasted Cauliflower Soup, involves adjusting ingredient quantities proportionally. But there’s more to it than just math.

Scaling Up

  • Ingredient Proportions: Keep ingredient ratios the same. If the recipe doubles, double all ingredient amounts.
  • Cookware Size: Use a larger roasting pan for the cauliflower and a larger pot for the soup. This prevents overcrowding, which can affect cooking times and outcomes.
  • Cooking Times: Roasting and cooking times may increase slightly when making larger quantities, especially if the oven or stove is crowded. Monitor closely to prevent burning.
  • Spices and Seasoning: When scaling up, increase spices and seasonings gradually. Some flavors can become overpowering when doubled.

Scaling Down

  • Ingredient Proportions: Halve the ingredients if you reduce the recipe by half.
  • Cookware Size: Use smaller cookware to maintain cooking times and ensure even heat distribution.
  • Cooking Times: Cooking times may decrease when making smaller quantities. Keep a close eye to prevent overcooking.
  • Spices and Seasoning: As with scaling up, adjust seasonings carefully. Some may need to be reduced less than others to maintain a balanced flavor profile.

What Is Used For Garnishing?

The garnishing for Roasted Cauliflower Soup can be varied based on personal preference. Here are a few options:

  • Fresh Herbs: Chopped fresh parsley, chives, or dill adds color and a fresh flavor to the soup.
  • Cheese: A grated Parmesan or sharp cheddar sprinkle can add a rich, savory note.
  • Cream: A swirl of cream or a dollop of Greek yogurt gives the soup a luxurious finish.
  • Croutons: Homemade or store-bought croutons add a satisfying crunch, filling the soup.
  • Nuts: Toasted almonds or pine nuts provide a nutty flavor and an interesting texture contrast.
  • Spices: A dash of smoked paprika or chili flakes can provide a pop of color and a hint of heat.
  • Roasted Cauliflower: Reserve a few roasted cauliflower florets for a visually appealing and tasty garnish.
  • Olive Oil or Truffle Oil: A drizzle of good quality olive oil or a few drops of truffle oil can elevate the soup’s flavor profile.

Can I Make Soup Recipe In A Slow Cooker Or Instant Pot?

You can adapt the Roasted Cauliflower Soup recipe for both a slow cooker and an Instant Pot.

Slow Cooker

  • Follow the initial steps of the recipe, roasting the cauliflower in the oven and sautéing the onions in a pan.
  • Transfer the roasted cauliflower and sautéed onions into the slow cooker. Add the spices, broth, and milk.
  • Set the slow cooker on low for 6-8 hours or high for 3-4 hours.
  • Stir in the sherry near the end of the cooking time.
  • For a thicker soup, blend some of the soup and return it to the slow cooker before serving.

Instant Pot

  • You can use the sauté function to cook the onions directly in the Instant Pot.
  • Still, roast the cauliflower in the oven for that caramelized flavor.
  • Add the roasted cauliflower, spices, broth, and milk to the Instant Pot.
  • Close the lid, set the valve to sealing, and cook on high pressure for 10 minutes.
  • Quickly release the pressure, open the lid, and stir in the sherry.
  • As in the slow cooker method, blend some of the soup for a thicker consistency if desired.

Can I Use Store Bought Broth, Or Should I Make My Own?

You can use either store-bought or homemade broth for your Roasted Cauliflower Soup. Both have their own advantages.

Store-Bought Broth

  • Convenience: It’s ready to use, saving you time and effort.
  • Consistency: You’ll get a consistent flavor every time you use it.
  • Variety: It’s available in several types (e.g., chicken, beef, vegetable) and flavors.

Homemade Broth

  • Flavor: You control the ingredients so that you can adjust the flavor to your liking.
  • Healthier: Homemade broth typically has less sodium and no preservatives or additives.
  • Cost-effective: You can make it from kitchen scraps like vegetable peelings and bones, reducing waste and saving money.

Can I Use Different Types Of Meat/Fish/Pasta/Vegetables For The Soup Recipe?

You can certainly customize the Roasted Cauliflower Soup recipe by adding other ingredients. However, keep in mind that adding different components can change the overall flavor profile of the soup.

  • Meat: Shredded chicken, cooked bacon, or diced ham could be great additions for a non-vegetarian version of the soup.
  • Fish: If you wish to add seafood, consider flaky white fish or even shrimp, but be mindful of their cooking times, as they cook faster than most meats.
  • Pasta: Small pasta shapes like orzo or pastina could fill the soup more. Cook the pasta separately and add it at the end to avoid it becoming too soft.
  • Vegetables: Feel free to add other vegetables. Root vegetables like carrots or parsnips would complement the cauliflower well. You could also add leafy greens like spinach or kale for added nutrition.

Success Tips – Tips And Tricks For Making Soup 

Success Tips for Making Roasted Cauliflower Soup:

  • Cauliflower Selection: Choose a firm, tight, and white head of cauliflower. Avoid those with brown spots or loose florets.
  • Cauliflower Size: Cut the cauliflower into small, even-sized florets. This ensures they cook evenly and at the same rate.
  • Seasoning: Season the cauliflower well before roasting. This step enhances the soup’s flavor.
  • Blending: Blend all or part of the soup for a creamier texture. Use an immersion blender for convenience or a stand blender for a smoother texture. Remember to cool slightly before blending if using a stand blender to avoid steam build-up.

Prepping Tips

  • Prep in Advance: Chop the cauliflower and onion the night before to save time on cooking day.
  • Mise en Place: Gather and measure all your ingredients before you start. This ensures a smooth cooking process.

Cooking Time Tips

  • Roasting Time: Keep an eye on the cauliflower while roasting. Over-roasting can make it mushy, while under-roasting can result in a lack of flavor.
  • Simmer Time: Allow the soup to simmer long enough for the flavors to meld together, but not so long that the cauliflower becomes mushy.

  • Roasting Time: Cauliflower’s roasting time can vary depending on the size of your florets and your oven. Keep an eye on them to avoid burning.
