Cheesy Broccoli and Cauliflower Soup

I have tried to develop this broccoli and cauliflower soup recipe a number of times, and every time it just wasn’t quite right. When this happens, I usually take a break and re-visit the recipe later. Last week I gave it another go and focused on a simple recipe and it came together so easily! I am in love with this broccoli and cauliflower soup recipe!

I usually make soups like this for lunch, or for dinner when Andy is going to be out of town. He isn’t a huge vegetable fan so this broccoli and cauliflower soup is not his idea of a delicious meal. HA! But Abram and I loved it. We have been eating it all week long!

Broccoli and Cauliflower Soup

The reason I love this recipe is that even though it is purred, it still has a rough texture and you can taste the broccoli and cauliflower. I kept the cheese mix simple as well, monterey jack for that perfect melt with a little parm to give it a kick.

The “secret” ingredient is a pinch of nutmeg. Nutmeg has this magical quality when added to creamy dishes, it enhances all the flavors and makes everything taste even more decadent and delicious.

I feel like this broccoli and cauliflower soup has a great balance of cream to veggies to cheese, you can taste everything – all the flavors are there and nothing is too overpowering. It’s simply divine!

And of course, some nice crusty bread is mandatory! Check out my homemade bread recipe or this amazing round-up post of 40+ Insanely Delicious Yeast Bread Recipes to by Gather for Bread find the perfect match!

      Hi Jan! Thanks for that clarification, I appreciate your question. I use either fresh or frozen of both the broccoli or cauliflower. If I’m using frozen, I just thaw it out (rinse under warm water) to be sure I’m getting as much as I want and there isn’t a lot of ice on it.
