How To Make This Cauliflower Soup
- Preheat and Prep: Preheat your oven to 425°F (220°C) and grease a baking sheet. Add the cauliflower, onion, and garlic, then season with salt and pepper.
- Roast the Vegetables: Spread everything into a single layer on the sheet. Roast for 15 minutes, then give everything a quick toss to ensure even browning.
- Finish Roasting: Return the pan to the oven and roast for another 10-15 minutes, until the cauliflower is golden on the edges and fork-tender.
- Simmer with Stock: Transfer the roasted veggies to a large pot. Add the stock and herbs, then bring the mixture to a gentle simmer over medium heat.
- Let Flavors Develop: Let the soup simmer for about 15 minutes, stirring occasionally to help the flavors come together.
- Cool Slightly: Remove the pot from heat and allow it to cool for 5 minutes before blending, which helps prevent steam buildup.
- Blend Until Smooth: Working in batches, carefully blend the soup until smooth, or use an immersion blender directly in the pot. Add the cream and blend again until silky.
- Season and Serve: Taste and adjust seasoning as needed. Serve hot, topped with crispy bacon, shredded cheese, and sprinkle of chives or green onions.
This cauliflower soup is hearty enough to stand on its own, but it pairs beautifully with a few simple sides. Serve it with crusty bread, Garlic Butter Pizza Pull Apart Bread, or a Spinach and Ricotta Grilled Cheese for a cozy, satisfying meal. For somehing lighter, try a crisp green salad or a side of roasted vegetables. And if you’re keeping it low carb, sautéed greens or Crispy Garlic Baked Potato Wedges make a great crunchy contrast.
Recipe FAQ’s
Simply swap the chicken stock for vegetable stock and skipped the bacon topping. The soup is still flavorful and creamy without the meat
An immersion blender is the easiest (and safest) option. But a countertop blender gives a super smooth mixture, just be sure to let the steam escape between pulses
Roasting brings out the nutty, caramelized flavor in the cauliflower and garlic, adding a richer, deeper taste to the soup that you won’t get from boling alone.

Loved this soup!! Made a couple of changes. We added a large carrot when roasting the vegetables. Cooked in crock pot on high for 5 hours with a bay leaf. I added 1 tsp of each of the suggested spices. Will made often! Thank you
Finally made this for the 1st time. We really enjoyed! Roasting the cauliflower with the onion and garlic gave it so much flavor. I used parsley with a pinch of thyme and rosemary. The green onions, bacon & provolone on top really kicked it up a notch. My husband cut up pieces of kielbasa & added to his soup. Can’t wait for leftovers tomorrow! Yum!
