In my house, making soup is a surefire way to get everyone to eat more vegetables. It always surprises me how quickly a container of soup disappears. This Creamy Cauliflower Soup and my Cream of Mushroom Soup are my family's clear favorites.
I make all my creamy vegetable soups the same way, and it's super simple. Saute onion and maybe some garlic in olive oil or butter. Add the vegetable, whether it's mushrooms, cauliflower, broccoli, butternut squash, carrots, or whatever you like. Cover with the best chicken broth you can find. I make my own, but some of the boxed versions are fine, and if you prefer vegetable broth, that works too. Cook until everything is tender, at least half an hour, sometimes more. Blend, adding a little cream, a squeeze of lemon, and salt and pepper to taste. And that's it.
This soup is great if you're on a low carb or keto diet, like me. If you want to skip the cream, add a small potato to the pot when you add the vegetables—it will act as a thickener and smooth everything out when you blend.

Creamy cauliflower soup
Simmer the cauliflower in the best quality chicken or vegetable broth you can find (or make your own), then add a splash of cream when you blend it.
Ingredients
- 1 large head cauliflower
- 3 Tbsp butter or olive oil
- 1 medium yellow onion, chopped
- 6 cups chicken or vegetable broth
- 1/2 cup heavy cream
- juice of 1 lemon
- salt and freshly ground pepper
Instructions
Cut the cauliflower into florets. Peel the tough outer skin off the stem, then chop the remaining inner stem into small pieces.In a large pot over medium heat, melt the butter or olive oil and saute the onion 4-5 minutes or until it turns translucent—don't let it brown. Add the cauliflower and chicken broth and bring to a gentle simmer. Turn down the heat and simmer the soup, covered, until the vegetables are very soft, about 30 minutes. Add the cream and lemon juice, then puree the soup in the pot with an immersion blender until very smooth, or transfer to a countertop blender, being careful not to burn yourself. Season with salt and pepper and serve immediately.
