Unlike most vegetable dishes, the key to this recipe is to completely overcook the broccoli. While this process may seem counterintuitive, this method ensures a silky smooth texture that doesn’t compromise on flavor. Our recipe is adapted from Cook’s Illustrated’s recipe, which calls for baking soda to help break the broccoli down further. Two ounces of sharp cheddar cheese is all you need to add the tangy creaminess that is essential to this classic recipe. This recipe can easily be doubled to accommodate more eaters or if you’d like to have leftovers.

Very tasty! As suggested, I doubled this to ensure leftovers. Served with some sourdough and it was great. Didn’t have enough powdered mustard so I subbed in 1T yellow mustard which was fine.
