How do I make the roasted cauliflower red pepper soup?
Begin by cutting the cauliflower florets off a head of cauliflower. Leave the florets fairly large so they don’t burn while roasting.
Cut the peppers, making sure to remove the stem and seeds.
Arrange the vegetables on parchment lined baking sheets, don’t crowd them, and drizzle with oil (picture 1).

Roast in the oven until the veggies are fork tender and the skin of the peppers has bubbled and blackened (photo 2).
Wait until cool enough to handle, then remove the skin from the red bell peppers (I have some tips below on how to do this) and place in the blender along with the roasted cauliflower (phots 3 and 4).
If you’d like, reserve a couple of the cauliflower florets to garnish your bowls of soup.
Blend while adding the vegetable broth until the soup is at your desired consistency.
Take a little taste test and season with as much (or as little) salt and pepper as you’d like!
Tips:
If you have a high speed blender such as a Vitamix 
or Blendtec 
, you don’t have to remove the skin from the peppers. Those appliances should be strong enough to properly blend the skins smoothly into the soup.
Leftovers can be stored in a covered container in the refrigerator for 4 to 5 days.
This soup freezes beautifully for up to 3 months!
How to peel roasted peppers?
I’m going to be honest with you, peeling the roasted red peppers is the most time consuming part of this recipe, but here are a couple different suggestions to make it a tad easier!
Once the peppers have been roasted, use tongs to transfer the peppers to a plastic bag and seal it. Once the peppers have cooled, open the bag and the skins should easily peel off.
While this is the most convenient way, I really don’t use this method as I’m a bit wary of placing hot food in plastic. However, if that’s something that doesn’t concern you, then it’s definitely the easiest route!
The alternative is to leave the peppers on the baking sheet for 15 to 20 minutes until cool enough to touch. Then, with some patience, use your fingers to remove the skins.

- Remove baking sheets from the oven. Once cool enough to handle (should take around 15 minutes), use your fingers to remove the skins of the red bell peppers.
- Place the peppers and cauliflower into the blender jar along with 1 cup of vegetable broth. If you wish, reserve a few cauliflower florets to garnish your soup bowls. , and two cups of vegetable broth in a blender. If you wish, reserve a few cauliflower florets to use as a garnish. Blend until smooth.
- Begin blending the soup and continue to add more vegetable broth until your desired consistency is reached. (I prefer my soup on the thicker side.)
