Why are oats used in Roasted Cauliflower Soup?
We’ve made this soup dairy-free by using oats to add an extra kick of protein and a super creamy flavor. Oats are a surprise ingredient and you’ll be delighted with how creamy this soup tastes!
Roasted Cauliflower Soup: quick and easy
Prep time is minimal since everything is roasted together on a sheet pan which also makes clean up easier because there are fewer dishes to wash. You can make the oats ahead to save time.
This Roasted Cauliflower Soup is a great allergy-friendly dinner recipe because you can blend all the ingredients together with liquid of choice and you’ll be enjoying dinner in less than an hour.
Did you know that you can roast garlic cloves and shallots for a full-flavored Cauliflower soup?
Roasting brings out the sweetness of root vegetables like garlic and shallots and when pureed into this soup infuses surreal flavor. It takes an hour to roast a whole head of garlic which is’nt always convenient but yes, you can still roast individual cloves with the same result. You won’t even need to peel the skins because they’ll slide right off once roasted.
If you have the time and want to roast a whole head of garlic and/or freeze a big batch of roasted garlic, find out how in our article, “Ten Freezer Friendly Foods, Tips and Tools”.
Water, broth or both?
I like to use an equal combination of water and broth for this Roasted Cauliflower Soup. Cauliflower has a delicate, subtle flavor and using all broth has a tendency to overpower the soup.
Whether you choose to use all water or a combination water/broth mixture, warm it up ahead. I like to warm my liquid up on the stove while the cauliflower is roasting. This way, when everything is blended together, your soup will stay warm and have a smooth consistency.

Description

Ingredients
- ¼ cup oats, cooked. We like Zego Double Protein, Purity Tested Oats
- 1 head large cauliflower, about 2 pounds, cut into even size florets. Rinsed & dry.
- 3 tablespoons EVOO ( olive oil, avocado oil or neutral oil) plus 1/2 teaspoon extra
- ½ teaspoon ground cumin
- ½ teaspoon ground coriander
- 2 teaspoon salt, divided plus 1/2 teaspoon extra or to taste
- ¼ teaspoon pepper
- 1 large shallot, skin on (about 1/3 cup rough chop after roasting)
- 3 cloves garlic, skin on
- Up to 6 cups water or (3 cups broth and 3 cups water). Less or more as needed.
- juice from 1/2 lemon or 2 teaspoon white wine vinegar
- ¼ cup fine chopped parsley, cilantro or sprouts for garnish
Instructions
- Preheat oven to 400 degrees.
- Measure out ¼ cup cooked oats. Set aside.
- In a medium size mixing bowl, toss cauliflower with 3 tablespoons oil, cumin, coriander, 1 teaspoon salt, pepper.
- Brush ½ teaspoon oil on skins of shallot and garlic until coated.
- On a large baking tray, lay cauliflower, shallot and garlic cloves flat. Do not crowd.
- Roast for 20-30 minutes or until cauliflower is tender and slightly caramelized around edges. Gently toss with a spatula once. Let cool on tray for a few minutes.
- Reserve ½ cup of cauliflower florets for garnish and slide skin off shallots and garlic.
- Rough chop shallot.
- Pour cauliflower, garlic, shallots and oats into a blender with three cups of warm water ( or warm water/broth combo) and cooked oats. Blend until smooth.
- Add pureed cauliflower mixture to a medium size pot with additional water or broth as needed, add 1 cup at a time up to 3 cups or to desired consistency. Warm.
- Add juice of lemon or vinegar and 1 to 1 1/2 teaspoon salt to taste.
- Top with roasted cauliflower, chopped parsley, pepper, red chili flakes and a drizzle of oil.
Notes
- Wash cauliflower & pat dry before roasting otherwise cauliflower will steam.
- Make sure florets are evenly chopped and have enough room to spread out on baking tray to ensure a consistent bake and carmelization.
- Use a bowl instead of a sheet pan to toss everything with oil. The round shape of your bowl ensures that the oil coats every part of the cauliflower.
- Soup will thicken when cool. Add liquid when reheating. Adjust with salt and pepper.
