The secret to this cheddar cheese soup is roasting the broccoli, which gives a rich caramelized flavor, adding depth and character to the dish.

You can forgo the roasting, but in my opinion, the extra time is worth the added flavor.

    This is one of the most delicious soups I have tasted in a long time. I made it 50/50 broccoli and cauliflower, and substituted some of the cheddar cheese with a tangy blue cheese. I made double the quantity so that I can freeze it for a quick, ready meal.

    • Hi,

      Hope you don’t mind me asking. I am cooking for just myself…how did it work out after freezing?

      There is only so much soup I can enjoy within 3 days.

      Thanks for your insight!

    This soup is FANTASTIC…the thyme and the roasted broccoli really make it!! I blended half of the broccoli in with the immersion blender, and stirred in the rest of the pieces to make it a little chunky. Perfect combo of flavors. I used Kerrygold grass fed butter and aged cheddar, and this was just out of this world good!!!

    • Hi Kim,

      I would choose the Coconut Cream over the milk for the higher fat content, and I think it would work nicely.
