Karlynn’s Recipe Notes

Skill Level: This soup is very easy to make.
Total Time: Making this soup will take approximately 6 hours.
Variations: Serve this soup chunky or smooth, depending on your preference. Add some spice with a few red pepper flakes, some diced hot peppers, a dash of your favourite hot sauce, or a pinch of cayenne pepper. Garnish with some extra crunchy bacon bits or fried onions.
Tools Needed: For this recipe, you’ll need a slow cooker, a medium pot, a blender or immersion blender, a whisk, a spoon, and a cheese grater.

What You’ll Need For Ingredients

Cauliflower: While this is a great way to use any leftover cauliflower you find hiding in your fridge, you could also buy a bag of frozen cauliflower from the grocery store. The frozen stuff is usually cut up already and will end up shortening your total cooking time.

Cheese: This recipe calls for shredded cheddar cheese, but you can use any cheese you like. Try a sharp or aged cheddar, something spicy like Monterey Jack, or something extra gooey like Gouda or Swiss. Have fun.

Roux: This mixture of melted butter, flour, and milk is the base for the cheese sauce and will thicken the soup. For more details about this process, check out How to Make a Roux.

How To Make Cheesy Cream of Cauliflower Soup

This is a brief overview of the recipe. The full list of ingredients and step-by-step instructions are in the recipe card below.

Put cauliflower, broth, and onions in slow cooker and cook on low for 5-6 hours.
In a medium pot, over low heat, melt the butter. Mix/whisk in flour and then slowly add milk, stirring or whisking constantly to avoid large clumps.
Add cheese to milk and stir until melted and smooth.
Move cauliflower to one side of the slow cooker and add cheese sauce to the soupy end so you can mix it thoroughly. Or puree the cauliflower and mix the sauce right into the smooth soup.
Whisk or mix until completely combined.
Cook for 15-20 more minutes, stirring occasionally.

Karlynn’s Tips and Tricks for Making Cheesy Cream of Cauliflower Soup

A Quicker Way: The slow cooker is great for when you need to be able to throw things in and leave them alone for a few hours. However, if you’d like to make this soup and don’t own a slow cooker, or if you need to have it made sooner, you can make this on your stove. Using a large pot instead of a slow cooker, simmer the cauliflower, broth, and onions until the cauliflower is soft. This shouldn’t take more then 30 minutes or so. Then, you can follow the rest of the steps from the recipe.

Thickening Options: One of the easiest ways to make this soup thicker is by using a little less milk or a bit more cauliflower. You can also use some half-and-half or whipping cream instead of milk if you’d like a creamier soup. Some people like to add some potatoes to their cream of cauliflower soup since the starch from the potatoes will thicken the soup to a certain degree. Don’t be afraid to experiment and figure out what works for you.

Storage Instructions

Fridge: Once it’s fully cooled, you can store the leftover soup in a sealed container in the fridge for 3-4 days. Reheat it in the microwave or in a pot on the stove.

Freezer: This soup, like most soups, will keep well in the freezer for a few months. Try freezing your soup in portion-sized containers so you can take out and reheat individual servings as you need them.
