Ingredients You’ll Need for Instant Pot Keto Cauliflower Soup

1 large head of cauliflower (cut into florets)
1 small onion, chopped
3 cloves garlic, minced
4 cups chicken or vegetable broth (make sure it’s keto-friendly, without added sugars)
1/2 cup heavy cream (you can substitute with coconut cream for a dairy-free option)
1 cup shredded cheddar cheese (optional for extra creaminess)
2 tbsp butter or olive oil (for sautéing)
Salt and pepper to taste
1 tsp thyme (optional for flavor)
1/2 tsp paprika (optional for a slight kick)
Chopped fresh parsley (for garnish)

Step-by-Step Instructions: How to Make Instant Pot Keto Cauliflower Soup

Step 1: Sauté the Vegetables

Set your Instant Pot to the sauté mode and add the butter or olive oil.
Once heated, add the chopped onions and garlic. Sauté for 3-4 minutes until the onions become translucent and fragrant. This step adds a deeper flavor to your soup base.

Step 2: Add the Cauliflower and Broth

Add the cauliflower florets to the Instant Pot, followed by the chicken or vegetable broth. Ensure the cauliflower is mostly submerged in the broth. If not, add a bit more liquid.
Season with salt, pepper, thyme, and paprika if you’re using them.

Step 3: Cook on High Pressure

Secure the Instant Pot lid and ensure the valve is set to sealing. Select the high-pressure mode and set the timer for 8 minutes. This quick cooking time is one of the major benefits of using an Instant Pot.

Step 4: Quick Release the Pressure

Once the cooking cycle is complete, do a quick pressure release by carefully turning the valve to venting. Let all the steam escape before opening the lid.

Step 5: Blend the Soup

Using an immersion blender, blend the soup directly in the Instant Pot until it’s smooth and creamy. If you prefer a chunkier texture, you can blend only half the soup and leave some cauliflower florets intact.
Alternatively, you can transfer the soup to a countertop blender and blend in batches if you don’t have an immersion blender.

Step 6: Add the Cream and Cheese

Stir in the heavy cream and shredded cheddar cheese. The cheese will melt into the soup, making it extra creamy and flavorful. If you’re avoiding dairy, you can skip the cheese or use a dairy-free alternative.

Step 7: Adjust the Seasoning

Taste the soup and adjust the seasoning with more salt, pepper, or spices if needed. The soup should be creamy and well-seasoned, with a slight hint of garlic and onion.

Step 8: Garnish and Serve

Ladle the soup into bowls and garnish with fresh parsley or additional cheese, if desired. Serve warm, and enjoy the rich, creamy flavor of this keto cauliflower soup!

Nutritional Benefits of Cauliflower Soup on a Keto Diet

One of the main ingredients, cauliflower, is a superstar when it comes to low-carb eating. It’s incredibly versatile and acts as a healthy, keto-friendly substitute for higher-carb ingredients like potatoes or grains.

Low in Carbs: With just 5g of carbs per cup, cauliflower is perfect for those on a low-carb or keto diet.
High in Fiber: It’s rich in fiber, which supports digestion and helps you feel full without adding many calories.
Packed with Nutrients: Cauliflower provides vitamin C, vitamin K, and folate, which are essential for a healthy immune system and overall well-being.

Tips for Customizing Your Instant Pot Keto Cauliflower Soup

Add Protein: If you want to make this soup more filling, consider adding cooked bacon, shredded chicken, or crumbled sausage. It will add protein and a savory element that pairs well with the creaminess of the soup.
Make it Dairy-Free: Swap out the heavy cream for coconut cream, and omit the cheese or use a dairy-free alternative. This way, you can enjoy a creamy texture without the dairy, perfect for those with lactose intolerance.
Spice it Up: For an extra kick, add red pepper flakes or a dash of cayenne pepper when you sauté the garlic and onions. You can also drizzle a bit of hot sauce on top when serving.
Add More Veggies: If you want to pack more nutrition into this meal, add chopped spinach, kale, or broccoli to the soup. These vegetables are keto-friendly and will boost the nutrient content of the dish.
