Ingredients

• 1 tablespoon olive oil (not extra virgin)
• 1 medium yellow onion, diced
• 2 cloves garlic, minced
• 1 head cauliflower, cut into florets
• 3 cups vegetable stock
• ⅛ teaspoon ground nutmeg
• 1 teaspoon salt
• ¼ teaspoon ground black pepper
• ¼ cup heavy cream or half and half – optional
• ½ cup sharp cheddar cheese, grated – optional

How To Make Instant Pot Cauliflower Soup

Step 1: Sauté the Aromatics

Turn your Instant Pot to the sauté setting and add 1 tablespoon of olive oil. Once the oil is hot, add the diced yellow onion. Cook, stirring occasionally, until the onion becomes translucent and soft, about 4 to 5 minutes. Add the minced garlic and sauté for another 30 seconds until fragrant, making sure not to burn the garlic.

Step 2: Add the Cauliflower and Seasonings

Add the cauliflower florets to the Instant Pot. Stir to combine with the onion and garlic. Sprinkle in the ground nutmeg, salt, and black pepper. Give everything a good stir to evenly distribute the seasonings.

Step 3: Pour in the Vegetable Stock

Pour 3 cups of vegetable stock over the cauliflower mixture. Make sure the cauliflower is mostly submerged. Give it one last stir to combine all the ingredients.

Step 4: Pressure Cook the Soup

Secure the lid on the Instant Pot and set the valve to sealing. Select the manual or pressure cook setting and set the timer for 8 minutes on high pressure. Once the cooking time is complete, allow the pressure to naturally release for about 10 minutes, then carefully quick release any remaining pressure.

Step 5: Blend the Soup

Using an immersion blender, puree the soup directly in the pot until smooth and creamy. If you don’t have an immersion blender, carefully transfer the soup in batches to a blender and puree, then return it to the pot.

Step 6: Add Cream and Cheese (Optional)

If you want a richer soup, stir in ¼ cup of heavy cream or half and half. Then add ½ cup of grated sharp cheddar cheese, stirring until melted and fully incorporated. Taste and adjust seasoning if necessary.

Step 7: Serve and Enjoy

Ladle the soup into bowls and enjoy immediately. For an extra touch, garnish with a sprinkle of cheese, a drizzle of olive oil, or some freshly ground black pepper.

Expert Tips

• Use a sharp knife and cut cauliflower florets into similar sizes for even cooking.
• Don’t skip the sauté step—cooking the onions and garlic first builds a rich flavor base.
• If you prefer a chunkier soup, blend only half the soup, leaving some cauliflower pieces intact.
• Be cautious when blending hot soup; use a towel to hold the blender lid to prevent spills.
• For a dairy-free version, omit the cream and cheese or substitute with coconut milk and dairy-free cheese.
• Adjust seasoning at the end since the cheese can add saltiness.
• To make it vegan, skip the cheese and use a plant-based cream alternative.

Variations and Customizations

• Add herbs: Fresh thyme or rosemary stirred in after cooking adds a wonderful aromatic element.
• Spice it up: Add a pinch of cayenne pepper or smoked paprika for a little heat and depth.
• Make it heartier: Toss in cooked chickpeas or white beans before blending for extra protein and texture.
• Use broth alternatives: Chicken broth can be used instead of vegetable stock if you prefer a non-vegetarian version.
• Top it: Garnish with crispy bacon bits (ensure halal source) or toasted nuts for crunch.
• Make it vegan: Use coconut milk instead of cream and skip the cheese or use plant-based alternatives.
• Serve with: Crusty bread, garlic croutons, or a side salad for a complete meal.

How to Store Leftovers

Leftover cauliflower soup stores beautifully and tastes just as good the next day. Allow the soup to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3 days. When reheating, warm gently on the stovetop or in the microwave, stirring occasionally to prevent scorching. If the soup has thickened in the fridge, add a splash of vegetable stock or water to loosen it up while reheating. For longer storage, you can freeze the soup in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQ

Can I make this soup without an Instant Pot?

Absolutely! You can make this soup on the stovetop by sautéing the onions and garlic in olive oil, then adding the cauliflower, stock, and seasonings. Simmer for about 20-25 minutes, until the cauliflower is tender. Then blend until smooth and add cream and cheese if desired.

Is it necessary to add cream and cheese?

No, the cream and cheese are optional but add richness and depth to the soup. If you prefer a lighter or dairy-free option, you can skip them and still enjoy a flavorful, creamy soup thanks to the cauliflower and stock.

Can I use frozen cauliflower for this recipe?

Yes, frozen cauliflower works well and can be a convenient substitute. You may need to reduce the cooking time slightly since frozen cauliflower cooks faster. Just use the sauté function to soften onions and garlic, then add frozen cauliflower and stock before pressure cooking for about 6 minutes.

How do I make this soup vegan?

To make this soup vegan, use vegetable stock (as recommended), skip the heavy cream or use a plant-based alternative like coconut milk or cashew cream, and omit the cheddar cheese or use a vegan cheese substitute.
