Ingredients
You probably already have most of the ingredients to make this soup in your pantry, fridge, or freezer!
- Cauliflower: You can use fresh or frozen cauliflower, it won’t impact the flavor either way.
- Vegetable Broth: I always use the low-sodium version of this vegetable broth because it doesn’t contain any added sugar or oil.
- Red Curry Paste: This is my favorite red curry paste, it has the most delicious, spicy flavor!
- Canned Coconut Milk: It’s important to use canned coconut milk in this recipe because the fat adds a lot of creaminess to the broth.
- Lentils: Red lentils are the best to use because they get very soft when cooked and easily break down when blended. The red lentil color blends perfectly with the rest of the ingredients too.
Step by Step Instructions
In a 6-quart dutch oven or large pot, saute the sliced onions until soft. Add the minced garlic and cook a few more minutes until fragrant (Photo 1). Add the cauliflower florets, curry paste, red lentils, water, broth, and dried seasonings (Photo 2). Let it cook until the vegetables and lentils are tender (Photo 3).
Carefully transfer the vegetable mixture to a large blender cup and blend it until it’s smooth and creamy (Photo 4). Pour the pureed soup back into the pot and stir in coconut milk and lemon juice (Photos 5 & 6).
Serving Suggestions
I like to serve this spicy cauliflower soup with a salad or baked potatoes with a couple of slices of Ezekial bread for dipping! The following side dishes would also be good options to serve:
- Cilantro Lime Quinoa
- Smoky Chickpea Lavash Wrap
- Avocado Arugula Tomato Salad
- Quinoa Spinach Salad with Mango Dressing
How Long Does it Last in the Refrigerator?
Store leftover soup in an airtight container in the refrigerator and it will stay fresh for up to 4-5 days.
Can I Freeze it?
Put the vegan curry cauliflower soup in an airtight container and freeze it for 2-3 months for the best quality.
How to Reheat it
From the Fridge: Reheat leftover soup in a bowl in the microwave for 1-2 minutes or in a small pot on the stovetop over medium heat until hot.
From the Freezer: When you’re ready to reheat the soup, take it out of the freezer and put it into the fridge to defrost for 24 hours and then you can reheat it on the stove or in the microwave.
Substitutions & FAQ
- Cauliflower Substitute: Two large (peeled and chopped) russet potatoes or sweet potatoes or 1 cup raw cashews can be used instead.
- Canned Coconut Milk Substitution: You can use unsweetened almond or cashew milk, but it won’t make the soup texture as rich and creamy.
- Can I use roasted cauliflower? Sure! Roast the florets at 400 degrees for 25 minutes and then add them to the blender cup when you blend the other ingredients.
- I added too much red curry and now it’s too spicy, how do I fix it? If you find that the flavor is too spicy for you, add 1 tbsp maple syrup (add more to taste) to cut the heat.
Success Tips
- 4 tbsp of curry paste gives this recipe a spicy kick. If you don’t like spicy food, start with 2 tbsp of curry paste and taste it before you add the last 2 tbsp. You can always add more, but you can’t take it away.
- Don’t discard the green cauliflower leaves! You can dice the leaves and add them to yellow cauliflower curry. The leaves are 100% edible and taste just like cauliflower.
- Use canned coconut milk (not coconut milk from a carton) to make the soup extra thick and creamy.
- Store the leftover vegan cauliflower soup in an airtight container in the fridge for 4-5 days or freeze it for a future meal.
