What’s in creamed cauliflower soup?
This creamy roasted cauliflower soup healthy recipe requires just eight simple ingredients along with a few pantry seasonings! Below is a comprehensive list of the ingredients you will need to make it:
Ingredients for this recipe
- Cauliflower: You will need one large head of cauliflower for this best cauliflower soup recipe. Make sure the head of cauliflower is approximately 2 1/2 pounds – give or take.
- Onion: You can use either a yellow onion or sweet onion, depending upon your personal preference
- Jalapeño: One large jalapeño adds a touch of smoky, earthy flavor as well as a touch of heat. If you don’t like anything spicy, make sure you remove the seeds and ribs of the jalapeño before dicing it.
- Seasonings: A combination of cumin, paprika, chili powder, salt, and pepper all provide a ton of flavor
- Garlic: Two cloves of garlic provide a subtle, yet distinctive punchy taste. Make sure you use fresh garlic, and not the minced variety sold in a jar
- Cannellini Beans: White beans are the secret ingredient to making this soup thick and ultra-creamy without loading it up with heavy cream. Thoroughly rinse and drain your white beans before using them in this recipe for roast cauliflower soup.
- Stock: Chicken or vegetable stock makes up the liquid base of this soup. Make sure you are using a no- or low-sodium stock.
- Substitute: Better than bouillon, chicken broth, or vegetable broth.
- Half and Half: A touch of half and half adds a luxurious layer of rich flavor. I suggest using the half and half to taste, using more for a richer mouthfeel.
- Substitute: Alternatively, you can use heavy cream if you want a truly rich creamed cauliflower experience!
- Bacon (optional): While entirely optional, bacon adds the perfect savory, salty and umami element to this cauliflower soup without cream.
Substitutions and variations
This cauliflower soup roasted recipe is somewhat flexible, so please feel free to substitute ingredients based upon your personal preference or what you have readily available!
- Leeks: If you prefer a milder, more delicate onion flavor, leeks are a wonderful substitute for regular onions. When using leeks, make sure you rinse them thoroughly and only use the white base and light green portion of the stalk in this cauliflower creamy soup.
- Serrano: If you prefer your soup with a spicy kick, you can substitute serrano peppers for the jalapeño. Jalapeños are much more mild in flavor and serrano peppers are (generally) about five times as spicy!
- Bell Pepper: If spicy isn’t your thing, swap the spicy jalapeno for a sweet bell pepper instead.
- Veggies: You can easily make this cauliflower soup even healthier by bulking it up with veggies. Carrots, celery, and sweet corn all taste great here.
- Seasonings: This cauliflower healthy soup recipe uses a combination of Tex-Mex seasonings; however, you can customize the seasonings to your liking. Ground coriander is a delicious addition, or you can totally switch up the seasonings and use a combination of cayenne + parsley, sweet paprika + thyme or cumin + coriander and turmeric.
- Vegetarian Option: If you are looking to make this a vegetarian cauliflower soup, simply omit the bacon and use vegetable stock instead of chicken stock.
How to make roasted cauliflower soup?
This creamy soup recipe with cauliflower is so simple and only requires 15 minutes of hands on preparation!
Roast Cauliflower: In a large mixing bowl, toss cauliflower florets with olive oil and seasonings. Transfer the cauliflower to a sheet pan and roast until the cauliflower is golden, about 20-30 minutes. Remove the cauliflower from the oven and set aside.
For the Soup – If using bacon: Add bacon to a Dutch oven and place over medium heat. Cook, stirring occasionally, until the bacon is crispy. Turn off the heat and use a slotted spoon to remove the bacon to a paper towel-lined plate. Set the bacon aside. If not using bacon, skip the above and heat 1 1/2 tablespoons of neutral oil in a Dutch oven or Stock Pot over medium heat. Proceed to next instruction.
Add vegetables: Return the heat to medium and add the onions and jalapeños, along with the seasonings. Sauté, stirring frequently, until the onion is soft and translucent. Add garlic and cook until fragrant, about 1 minute.
Add remaining ingredients & simmer: Add the roasted cauliflower, cannellini beans and stock to the pot. Bring the soup to a boil and immediately reduce heat to a gentle simmer. Simmer for 10-12 minutes, or until the vegetables are very tender.
Puree: Turn off the heat and use an immersion blender to puree soup until smooth and very creamy. (Alternatively, you can transfer the soup in batches to a stand blender, puree, and transfer back to pot). Add half-and-half: Return heat to low and stir in the half-and-half. Taste and adjust for seasoning.
Serve: Ladle the healthy roasted cauliflower soup into serving bowls. Garnish the top with bacon and your favorite toppings. Serve the roast cauliflower soup immediately and enjoy!

FAQs: cauliflower healthy soup
How to puree cauliflower for soup?
There are two ways you can puree cauliflower when making soup recipes – an immersion blender or a stand blender.
- Immersion Blender: Using an immersion blender is the quickest, easiest, and least messy way to puree cauliflower for soup. Before using your immersion blender, make sure you turn the heat off underneath the pot! Next, insert the blender into the pot and puree the soup until it is creamy and thick in texture.
- Stand Blender: Using a stand blender is a bit more cumbersome than an immersion blender; however, it works great! To use a stand blender to puree, transfer the roasted cauliflower soup from the pot to the blender in batches (don’t fill the blender up to the top). Pureeing in batches will help you avoid the hot soup from exploding out the blender, as hot soup steams and expands which will push the top off of the blender. Once you have a portion of the soup in the blender, use a towel and press down to cover the top of the blender. Next, puree the cauliflower until it’s creamy and thick in texture. Once blended, transfer the roast cauliflower soup soup back to the soup pot and repeat pureeing in batches until all the soup is creamy and thick.
Serving healthy cauliflower soup recipes
You should serve this creamed cauliflower healthy soup warm or hot – as soon as possible after making it. While you can serve soups at room temperature or cold, they will lack the same depth of flavor and they won’t be very appetizing.

What toppings can I add?
Toppings and garnishes are the perfect way to customize your roast cauliflower soup recipe and transform it from good to GREAT!! Soup toppers can range from crunchy or creamy, and salty or savory, to herbaceous. You can choose to add one or more topping to your roast cauliflower soup, depending upon your preference. Or set a bunch of toppings in individual bowls and let your family pick their favorites!
Toppings for soup
- Bacon: This roasted cauliflower soup recipe includes crispy, salty, umami-packed bacon as a garnish.
- Cheese: Shredded or grated cheese is the perfect complement to roasted cauli soup. I love using cheddar; however, parmesan, gruyere, Colby jack, mozzarella and provolone will also taste great.
- Herbs: Fresh herbs are a wonderful way to add a touch of herbaceous, fresh flavor. Green onions, chives, cilantro, parsley and thyme are all delicious topping options.
- Sour Cream: Since this cauliflower soup is creamy it’s begging for a dollop of tangy sour cream for an ultra-luxurious mouthfeel.
- Chips: Crushed tortilla chips, tortilla strips, or pita chips are a fun, crunchy topping option.
- Croutons: If you prefer a traditional crunchy element, you can never go wrong with a scattering of croutons as a topping.
- Chickpeas: Crispy roasted chickpeas are a delicious option if you are looking for a healthier topping.
- Cauliflower Florets: Reserve a few roasted cauliflower florets to use as an easy and visually pleasing garnish.

How to reheat leftovers?
You can reheat your leftover cauliflower soup two different ways! If the leftover soup has become thicker during storage, simply add a bit of stock, broth or cream (half-and-half) to thin it out.

- ½ - 1 Cup Half and Half - to taste (SEE NOTES)
- Optional Garnishes: Pico de Gallo Sour Cream, Tortilla Strips, , Cilantro, Shredded Cheddar Cheese, Lime Wedges
- Preheat oven: Arrange oven rack to the center position and preheat the oven to 425-degrees Fahrenheit (or 400F convection). Next, line a large sheet pan with aluminum foil for easy clean up and set it aside.
- Season Cauliflower: Place the cauliflower florets into a large bowl and drizzle with the olive oil. Toss to coat the cauliflower in the oil. Next, sprinkle 1 teaspoon cumin, ¾ teaspoon paprika, ¾ teaspoon chili powder, ½ teaspoon salt, and 1/8 teaspoon pepper all over the cauliflower. Then toss well to thoroughly coat the cauliflower with the seasonings.Roast Cauliflower: Transfer the seasoned cauliflower florets to the prepared sheet pan. Place the pan in the oven and roast, turning the cauliflower over once during baking, for about 20-30 minutes or until the cauliflower is golden and caramelized. Remove from oven and set aside.
- Start the Soup - Using Bacon: Add bacon to a Dutch oven or stock pot and place over medium heat on the stove top. (Tip: start the bacon in a cold pot). Cook, stirring occasionally, until cooked through and crispy, about 8-12 minutes. Turn off the heat and use a slotted spoon to remove the bacon to a paper towel-lined plate. Set the bacon aside. Blot or pour off all, except about 1 ½ tablespoon of bacon fat. -OR-Start the Soup - NO Bacon: If you don't want to use bacon, heat 1 1/2 tablespoons of neutral oil in the pot over medium heat until shimmering. Once the oil shimmers, go to next step (adding veggies).
- Add vegetables: Return the heat to medium and add the onions and jalapeños. Season with ½ teaspoon cumin, ¼ teaspoon paprika, ¼ teaspoon chili powder, 1 teaspoon salt and 1/8 teaspoon of pepper. Sauté, stirring frequently, until the onion is soft and translucent, about 4-5 minutes. Add garlic and cook until fragrant, about 1 minute.
- Add cauliflower, beans, and stock: To the pot, add the roasted cauliflower, cannellini beans and stock. Give everything a good stir and then increase the heat under the pot to high to bring the soup to a boil. Once boiling, immediately reduce the heat to maintain a gentle simmer.Simmer Soup: Simmer the soup - UNCOVERED - for 10-12 minutes, or until the cauliflower is very tender.
- Blend Soup: Turn the heat off underneath the pot. Then use an immersion blender to puree soup until smooth and very creamy. (Alternatively, you can transfer the soup in batches to a stand blender, puree, and transfer back to pot). Add half-and-half: Return the pot to the stove-top over LOW heat. Stir in the half and half and cook for 1-2 minutes, or until soup is hot throughout. Taste the healthy cauliflower soup and adjust the seasonings as you see fit.
- Serve: Ladle soup into serving bowls. Sprinkle the reserved bacon over the soup and top with your favorite garnishes. Serve immediately and enjoy!
- Bacon: I use center-cut bacon because it is leaner with less fat. However, you can absolutely use your favorite variety of bacon in this soup!
- To make this vegetarian: Omit the bacon from ingredient list and skip step #3. Use 1 1/2 tablespoons of extra-virgin olive oil to sauté onion and jalapeños in step #4.
- Spicy Level: If you don't like a lot of heat, make sure you remove ALL the seeds and the ribs from the jalapeno before dicing. If you prefer a bit of spicy heat, leave some of the seeds and ribs intact!
- Half-and-Half: I use low-fat Half and Half; however you can use whatever you can use full-fat or heavy cream if you prefer a richer mouthfeel!
- Blender: If you are using a stand blender to puree the soup, make sure you puree the soup in batches to avoid the hot soup from exploding out of the blender. Hot soup will steam and expand in the blender, which will push the top off of the blender (hence causing a soup explosion), so always make sure you puree in batches and avoid filling the blender all the way to the top!
