It transforms humble cauliflower into a luxuriously creamy, silky soup using simple pantry staples and your trusty Instant Pot. The melt-in-your-mouth texture comes from a secret blend of coconut milk and raw cashews, while warming spices like cumin add a gentle aromatic hug in every spoonful. Whether you’re new to plant-based soups or a seasoned vegan, this recipe proves that healthy eating can be incredibly satisfying and easy to whip up any day of the week.

Ingredients You’ll Need

Gathering a handful of wholesome ingredients is all it takes to create this comforting soup. Each one plays a vital role: the cauliflower brings body and that subtly sweet earthiness, cashews add creaminess without the dairy, and spices bring life and warmth to the bowl.

• 1 head cauliflower (~2.5 lbs): The star ingredient, providing a mild, slightly nutty flavor and a smooth texture when blended.
• 1/2 white onion, chopped: Offers a subtle sweetness and builds a flavorful base for the soup.
• 2 cloves garlic, minced: Adds depth and a gentle zing that elevates the overall taste.
• 1 can full fat coconut milk: Creates that indulgently creamy texture while keeping it vegan and rich.
• 1 cup raw cashews: Blended cashews give the soup a silky consistency; raw is essential to avoid a roasted flavor.
• 2 cups chicken broth or vegetable broth: Provides savory richness and balances the creaminess with umami notes.
• 1 teaspoon sea salt (more or less to taste): Brings all flavors together and enhances the natural sweetness of the cauliflower.
• 1 teaspoon ground cumin (more or less to taste): Infuses a gentle earthiness that warms the palate.
• 1/2 teaspoon ground black pepper (more or less to taste): Adds a slight kick and complexity without overpowering.

How to Make Easy Instant Pot Cauliflower Soup (Healthy & Vegan) Recipe

Step 1: Prep Your Cauliflower and Aromatics

Start by chopping your cauliflower into bite-sized florets. This helps them cook evenly and blend smoothly later. Toss those florets into the Instant Pot first, creating the foundation of your soup. Then add your chopped onions and minced garlic—these aromatics will infuse the broth with flavor as it cooks, so don’t skip them!

Step 2: Add the Creamy, Flavor-Building Ingredients

Pour in the full-fat coconut milk along with the raw cashews, which are key for that indulgent, velvety feel. Then, pour your broth over everything, making sure the cauliflower is nicely submerged. Sprinkle in your sea salt, cumin, and black pepper on top so the flavors meld throughout the cooking process.

Step 3: Pressure Cook and Blend

Seal your Instant Pot lid and set it to cook on high pressure for 10 minutes. This timeframe is perfect for tenderizing the cauliflower and letting the flavors marry beautifully. Once done, release the pressure—either quick or natural release works. Use an immersion blender right in the pot to blend everything into a perfectly smooth, creamy soup that looks and tastes like it took hours to make.

Step 4: Taste and Adjust

Before you ladle it out, give your soup a tasting. This is your moment to adjust the salt, pepper, or cumin if needed. Remember, this is your creation—making it just right is part of the fun!

How to Serve Easy Instant Pot Cauliflower Soup (Healthy & Vegan) Recipe

Garnishes

Simple garnishes can take this soup from rustic comfort to something truly special. Try topping your bowl with freshly chopped parsley or chives for a fresh, color pop. A drizzle of extra coconut milk or a sprinkle of smoked paprika adds both visual appeal and extra flavor layers. Crispy roasted chickpeas or pumpkin seeds bring a delightful crunch that contrasts wonderfully with the soup’s silkiness.

Side Dishes

This soup shines as a standout starter or main, especially when paired with a crusty slice of hearty bread or a warm flatbread. For a light meal, serve alongside a crisp, tangy green salad with a lemon vinaigrette to brighten and balance the creamy richness. Roasted vegetables or a grain bowl also complement it beautifully if you want a more filling spread.

Creative Ways to Present

Why not turn this into a fun dish presentation? Serve the soup in hollowed-out sourdough bread bowls for a rustic look that makes every spoonful extra comforting. Layer it as a creamy base under a vibrant vegetable medley for a colorful, nourishing lunch bowl. Or add a swirl of pesto or chili oil within each serving for a gourmet touch that will impress everyone at the table.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer your leftover Easy Instant Pot Cauliflower Soup (Healthy & Vegan) Recipe into airtight containers and store in the fridge. It will stay fresh and flavorful for up to 4 days, making it a fantastic option for quick lunches or weeknight dinners.

Freezing

FAQs

Can I use roasted cashews instead of raw?

Raw cashews are best because they blend into a smooth, neutral-tasting cream. Roasted cashews add a toasty flavor that can overpower the delicate soup.

Is this soup gluten-free?

Yes, the Easy Instant Pot Cauliflower Soup (Healthy & Vegan) Recipe is naturally gluten-free as long as you use gluten-free broth.

Can I make this soup without an Instant Pot?

Absolutely! You can simmer the ingredients in a large pot on the stove until the cauliflower is tender, then blend until smooth. It will take a bit longer but is just as delicious.

What can I substitute for cashews if I have a nut allergy?

Silken tofu or cooked potato can be used for creaminess in place of cashews, though the texture and flavor will be slightly different.

How spicy is this soup?

This recipe is mild and warming thanks to cumin and black pepper, but you can easily add chili flakes or cayenne if you prefer a little heat.
