📖 Recipe

This is my favorite vegan cauliflower soup recipe. It’s easy and delicious, loaded with chunks of cauliflower and carrots and creamy red lentils. This soup is flavorful, nutritious, warm and comforting, exactly what you’re looking for!

This partially pureed lentil and cauliflower soup is all about well rounded nutrition that puts cravings on the back burner and lets your energy soar….but not at the sacrifice of great taste! This is Easy Cauliflower Soup is one that EVERYONE in my family adores…score a big one!!! All hands up for a one pot vegan meal that EVERYONE will eat!

I had an outdoor get together with friends and a fire pit….put a double batch of this in the crockpot, plugged in outside. And guess what? Nothing was left…that’s right. Even non-family calls this THE Best Cauliflower Soup Recipe….and you will too!

Ingredients and Substitutions

Labeled ingredients: Carrots, vegetable broth, celery, cauliflower, red lentils, onion, garlic, spices.

CAULIFLOWER: Low in calories and carbs, and high in vitamins, nutrients, fiber, and antioxidants. Use fresh or frozen florets to provide bulk. Vegan creamy cauliflower soup with no cream…just cauliflower that’s been partially pureed.
RED LENTILS: Awesome plant based source of protein, that are also rich in fiber, folate, iron, phosphorus, magnesium, zinc and potassium. They’re awesome for this pureed lentil soup since they cook up more quickly than other types of lentils and fall apart easily providing texture and naturally thicken the soup.
CARROTS: I used some orange and some purple…just to add color to this soup, but you can use whatever color carrots you have. Substitute parsnips if you don’t have any carrots.
CELERY: Another nutrient dense ingredient…meaning it’s low in calories and high in fiber and nutrients. Celery also helps with constipation, fights inflammation and reduces stress hormones. If you need a substitution, use a small bulb of fennel.
ONIONS: White, yellow or sweet vidalia onions will all work well. You could also use leeks, scallions or even shallots in a pinch.
GARLIC: Garlic isn’t just a flavor builder, it also helps fight inflammation, build immunity and is loaded with antioxidants. Let it sit for 10 minutes after mincing to release the anti-bacterial components.
SPICES: Cumin and coriander offer flavor, turmeric offers some additional anti-inflammatory benefits and salt and pepper are added for taste. Simple, yet effective.
VEGGIE BROTH: Here’s my EASY recipe for Veggie Stock. It is worth making it yourself to avoid unnecessary sodium and inferior quality oils. I freeze mine in quart mason jars, or 1 cup cubes so I always have the amount I need at my fingertips. If you buy already made broth, be sure to read the ingredient label to know what you’re getting. Look for a brand with the least amount of sodium, processed oil and the most wholesome, real ingredients you can find. s

How to make Healthy Cauliflower Soup:

Get your ingredients ready before you begin. Dice the onion, slice the carrots and celery, mince the garlic. Rinse and drain the red lentils. Measure the spices. Cut cauliflower into florets.

Diced onions inside a dutch oven, cooking.

Heat a dutch oven or soup pot over medium heat. Saute the diced onions in 1 Tablespoon veggie broth. If the pan becomes dry before the onions become soft and clear, add another Tablespoon broth, or 1 Tablespoon water. You can also saute in olive oil, if you prefer.

Soup is done when all the veggies are tender. Use an immersion blender to puree some, to create a creamy cauliflower and red lentil soup base. Leave some of the cauliflower and carrots whole, if desired. If you don’t have an immersion blender, puree in batches using your blender or food processor.

Taste for seasoning. Sprinkle on additional salt and pepper as desired and garnish with some fresh parsley.

Debra’s Pro Tips

Chunky vegetable soup with creamy lentil broth.

A mix of creamy and chunky is my favorite way to enjoy this soup. I use my immersion blender to puree just some, until the base is thickened, but some pieces of veggies remain.
Just 5 minutes of patience to slowly build flavor with the onions, chopped veggies, spices and garlic will be greatly rewarded in the finished product.
Freeze in individual serving sizes…you’ll be so thankful to have an easy lunch when you need it.
Speaking of lunch….put some in a thermos and take it to work or school.

MEAL PREP AND STORAGE

TO SERVE: Serve warm with crusty bread, or crackers. A simple green salad or arugula avocado salad will go well with this soup.
TO PREP AHEAD: Chop onions, carrots, celery and cauliflower up to 2 days in advance. Store chopped veggies in storage containers in the fridge. Make soup when it’s convenient for you and reheat when ready to serve.
TO STORE: Store in airtight container in the fridge for up to 5 days or the freezer for 3 months.
TO FREEZE: Keep in mind, soup will expand when it freezes so leave a bit of space in your container. Use freezer safe zip top bags or wide mouth mason jars.
TO REHEAT: Reheat gently over medium heat on the stovetop, until heated through.

Cauliflower Red Lentil Soup FAQs

Is Red Lentil Soup good for you?

Yes! Red lentils contain protein, fiber, vitamins and nutrients for a low cost of calories. When blended into soup, they provide bulk and creaminess too.

Do I need to soak red lentils for soup?

No. Red lentils should be rinsed, picked over and drained before adding to soup, but they do not need to be soaked.

How do you fix bland cauliflower soup?

Start your soup with plenty of aromatics (onions, garlic) and spices (cumin, coriander, crushed red pepper, sea salt) to build flavor as they’re cooked. Also use a vegetable broth that is tasty! I prefer homemade vegetable broth that has flavor from vegetables rather than oils or sodium. If you’ve already made a cauliflower soup and it is bland, try adding some white pepper, garlic powder, or toasted cumin.
