How To Make Instant Pot Cauliflower Soup
So, what do you need? Wholesome, authentic and homemade ingredients that you probably already have in your kitchen!
- 2 tablespoons butter
- 1 onion, chopped
- 1 tablespoon minced garlic
- 1 large head cauliflower, chopped (about 2-1/2 lbs)
- 2 cups chicken broth
- 1 teaspoon salt
- 1 teaspoon dry thyme
- 1/2 teaspoon ground pepper
- 1 brick, 8 oz, cream cheese, cubed
- 1/2 cup shredded cheddar cheese
- chopped green onions, optional for serving.
Notes, Tips and Suggestions
Yes, you can use frozen cauliflower if needed. But fresh is better! Our version of this cauliflower soup is pretty thick, almost like chowder. That’s how we like it. If you want to make it a little thinner, you can increase the broth to 3-4 cups.
As mentioned above, if you are looking for a vegetarian friendly soup, simply sub the chicken broth for vegetable broth.
And, finally, as with any soup, add salt to taste! Having the right amount of salt in this cauliflower soup is key!
Other Topping Suggestions
- Any shredded cheese- Of course Cheddar is awesome, but Swiss Cheese would be delicious too. Or Pepper Jack Cheese to give it a little kick!
- Bacon- Ummm… Yep. Bacon!
- Pulled Pork- Got some leftover BBQ? Put it on top of this soup for a delicious flavor combo!
- Green Onions-Add a great texture and flavor!
- Sour Cream-Yum!
- Sriracha Sauce- Drizzle a little over some sour cream for some serious heat!
- Crispy Fried Onions- Crispy fried onions are great on everything. Right!?!?!
