It’s an easy soup that feels comforting enough for chilly evenings but light enough to enjoy any time of year.
Soup season is always a great excuse to make a batch of this recipe, but I honestly enjoy it year-round. It’s a wonderful way to use fresh cauliflower, and it makes an easy lunch or simple dinner when paired with a salad or sandwich. Since it reheats well, it’s also a great option for meal prep during busy weeks.
I love making this soup in the Instant Pot because it softens the cauliflower quickly while locking in flavor. Instead of relying on heavy cream, the cauliflower creates a naturally creamy texture, while Parmesan adds richness without making the soup feel overly heavy. The sun-dried tomatoes add little bursts of savory flavor to each bowl, making this recipe stand out.
Check out this Air Fryer Zucchini Parmesan because both recipes let Parmesan shine without overpowering the vegetables. If you’re a soup lover, my Sausage and Mushroom Soup or this 4 Ingredient Potato Soup is another hearty option that’s full of flavor. Looking for another delicious way to use cauliflower?

Ingredients
Here is a quick look at what you will need. You can find the full measurements in the recipe card below.
- Cauliflower florets – Cauliflower is the star of this soup and naturally creates a creamy texture once cooked and blended. Fresh cauliflower works best, but frozen florets can also be used if needed.
- Minced garlic – Garlic adds savory flavor that complements the Parmesan beautifully. Fresh garlic gives the soup the best flavor, but jarred minced garlic works well for convenience.
- Shredded Parmesan cheese – Parmesan gives the soup its rich, nutty flavor while helping create a creamy consistency. Freshly grated Parmesan melts more smoothly than the shelf-stable variety.
- Sweet onion – Sweet onion balances the savory flavors and becomes mild as it cooks. Yellow onion is another good option if that’s what you have on hand.
- Chicken broth – Chicken broth forms the flavorful base of the soup while keeping it lighter than using cream. Vegetable broth works well if you want a vegetarian version.
- Sour cream – Sour cream adds extra creaminess along with a slight tang that brightens the soup. Stir it in after cooking for the smoothest texture.
- Garlic salt – Garlic salt boosts the savory flavor throughout the soup. Taste before adding extra salt since the Parmesan also contributes saltiness.
- Seasoned pepper – Seasoned pepper adds gentle seasoning without overpowering the cauliflower. Freshly cracked black pepper can be substituted if you prefer.
- Sun-dried tomatoes – Sun-dried tomatoes add little pops of bold flavor that pair surprisingly well with the creamy soup. Drain them well before adding if they’re packed in oil.
- Crumbled bacon – Bacon adds a crispy topping and smoky flavor that contrasts nicely with the creamy soup. It’s optional, but it makes a delicious garnish.
- Green onions – Fresh green onions add color and a mild onion flavor just before serving. They also brighten each bowl with a little freshness.

How to make this Parmesan cauliflower soup
Step 1: Rinse the cauliflower and cut it into small florets so it cooks evenly. Smaller pieces cook faster and blend into a smoother soup later.
Step 2: Chop the onion into small pieces and mince the garlic if you’re using fresh cloves.
Step 3: Step 2: Add the cauliflower, onion, garlic, broth, seasonings, and Parmesan to the Instant Pot and stir well. Cook until the cauliflower is fork-tender, then carefully release the pressure and blend until smooth. Stir in the sour cream and sun-dried tomatoes, adjust the seasoning if needed, and top with bacon and green onions before serving.
Recipe Tips
- Blend the soup until it’s as smooth or as chunky as you like. An immersion blender makes this easy, but a regular blender works too. If using a countertop blender, blend in batches and be careful with the hot liquid.
- If the soup seems thicker than you’d like after blending, stir in a little extra chicken broth until it reaches your preferred consistency. If it’s too thin, let it simmer for a few extra minutes to reduce.
- Add the sour cream after the soup has finished cooking. Stirring it in at the end keeps it smooth and creamy while preventing it from separating.
- Freshly grated Parmesan melts much better than the shelf-stable variety. It creates a smoother texture and gives the soup a richer flavor.
- This soup tastes even better the next day. The flavors continue to develop as it sits, making leftovers perfect for lunch or an easy dinner.
Serving Suggestions
- Main Dish: Pair this soup with my Air Fryer Zucchini Parmesan for a comforting vegetarian-inspired meal. The crispy zucchini adds a nice contrast to the smooth, creamy soup while keeping dinner balanced.
- Side Dishes: A bowl of this soup goes perfectly with Crispy Cauliflower Bites if you’re feeding a crowd or want another fun way to enjoy cauliflower. For something lighter, serve it with a simple green salad tossed in your favorite vinaigrette.
- Lunch Pairing: Serve a smaller bowl alongside a Chipotle Chicken Sandwich or wrap for an easy lunch that feels filling without being too heavy. The creamy soup pairs well with lean proteins and fresh vegetables.
- Dessert: Finish your meal with No Bake Mini Cheesecakes for a lighter dessert that complements the savory flavors of the soup without feeling overly rich.
