This was probably one of the more difficult recipes for me to develop, but not because I couldn’t figure out the flavors and consistency, but because I couldn’t get myself to STOP eating the hot roasted cauliflower coming out of the oven every time I tried to make this soup! Cauliflower is one of those vegetables I use frequently in my cooking, such as here, because it provides a nice texture, but it was never a veggie I truly enjoyed. However, with this dish, I discovered a whole new element of cauliflower, oven-roasted, which is absolutely amazing.
As I mentioned, when I first developed this recipe I couldn’t stop eating the roasted cauliflower hot straight out of the oven. Before I realized it, I had finished over half, straight from the baking sheet! I eventually finished this delicious recipe for Roasted Cauliflower & Mushroom Soup! Although I ended up going in a completely different direction when developing this recipe in terms of ingredients and cooking method, the initial inspiration for combining both mushroom & cauliflower into a creamy soup came from Kalyn’s Kitchen‘s Mushroom & Cauliflower Pressure Cooker Soup.
Overall, this soup is very easy to make and full of flavor. My favorite part about this soup is the ‘chunky’ texture. Instead of completely pureeing this soup, I pulsed it a few times to keep some of the veggies intact so that it’s not only nice and thick, but you can also taste the roasted cauliflower and mushroom pieces in the soup. I served this soup for dinner with a side of toasted french bread, and even my kids loved it. I was fortunate to have some leftovers for lunch the next day. In fact, after the soup had some time to sit, even more of the flavors were brought out. The flavor of the mushrooms also really comes through in this soup, so if you’re a mushroom lover, this recipe is definitely for you!
You can probably guess what I will be experimenting more with in this next month… yep, something involving oven-roasted cauliflower!
I’m also excited for the next few weeks because I have some exciting giveaways planned for all of you!
UPDATE: I recently modified this recipe to Veganize it, and it turned out delicious! I’ve added the modifications below for a vegan-option.

Roasted Cauliflower and Mushroom Soup
- 1 small head cauliflower , cut into florets
- 1 lb. mushrooms , white button, cremini, and/or shitake, thinly sliced
- 1 teasp fresh thyme , chopped
- 2 springs green onions , green parts, finely chopped
- 3 cloves garlic
- 1/4 cup dry white wine
- 3.5 cup low sodium vegetable broth
- 1/2 cup unsweetened non-dairy milk , such as SILK unsweetened cashew milk (see notes below)
- 1/2 cup vegan parmesan cheese , optional (see notes below)
- 3 tbsp olive oil , divided
- Preheat the oven to 400 degrees.
- Toss the cauliflower florets with 2 tbsp olive oil, salt and pepper.
- Spread the florets in a single layer on a baking sheet lined with parchment paper.
- Roast in the oven for 20-30 minutes until the florets are golden brown. In the meantime, continue on to the following steps.
- In a large non-stick pot, heat 1 tbsp oil on medium heat. Add the garlic and fry for a few seconds until fragrant.
- Immediately add the mushrooms and thyme and saute on medium heat until the water released from the mushrooms is mostly evaporated and the mushrooms themselves are tender.
- Add the green onions and cook for an additional 5 minutes, mixing frequently.
- Add the white wine and cook until the liquid reduces to about half the volume, mixing frequently.
- Add the roasted cauliflower and vegetable broth and bring to a boil. Once boiling, reduce the heat and simmer for about 30 minutes, covered.
- Season with salt and pepper to taste.
- Using a stick immersion hand blender , puree soup in brief pulses until you reach the desired thickness and chunkiness. Note that some of the mushrooms and cauliflower in the soup should be in pieces so that the soup is "chunky" in nature and not completely smooth.
- If using, add the non-diary milk and vegan parmasan cheese and simmer on medium heat for about an additional 10 minutes.
- Season to taste with salt and freshly ground black pepper.
- Serve the soup hot with a side of your favorite bread.
