Expert Recipe Tips
- Time savers: Buy pre-cut cauliflower, broccoli and carrots to save time.
- Creaminess: Whipping cream makes the creamiest of soup while whole milk will yield a thinner soup broth.
- Freezable: Makes great freezer meal lunch or dinners. Freeze in individual 16 oz. food grade containers. Allow the soup to cool to room temperature before transferring to freezer containers.
- Extra creamy soup: for a chunk free creamy soup use a slick blender to blend the vegetables into small pieces. If you have to use a blender you will have to do it in batches because all of the soup will not fit in the blender at once.

Thank you, Arlene, for such a great recipe. Proof that simple quality ingredients, properly matched can satisfy. I appreciate that there is no onion and just a small amount of garlic. I added a bit of cheese and a few small pieces of broccoli on top to garnish. I will be making this many, many times. Delicious and filling.

I love soups like this and the fact that you made this in the Instant Pot makes it all that much better. I have never put sherry in my soups but I think it's something I would love. I'm going to try it! Great post!

We are certainly tired of cold weather but one thing we're not tired of is delicious sounding soups like this. This is the first winter we've spent north in a long time and our bodies just aren't used to it. We've eaten more soups in these past three months than we have in three years. We're always looking for different flavors and textures in soups. This creamy soup sounds wonderful and we do have a stick blender so the soup is perfect for the weekend.
