Why You Will Love This Recipe
Hello Friends! I hope you are having a great week. It has been a productive week at our home as I have been cleaning out my craft closet and pulling out the Christmas decor.
Today’s recipe is a cheesy cauliflower dish that is wonderful to serve at dinners. The cauliflower is a vegetable that I have only recently embraced. Since I follow weight watchers during the week (on most weeks - ahem), this low carb vegetable tastes a lot like potatoes but saves you calories and carbs.
If you have never made a cauliflower dish, this is a great one to try. The tender cauliflower is blended with a creamy cheese sauce, then topped with bacon. This makes a delicious side dish for your holiday dinner.
Cauliflower has about ⅕ of the calories that potatoes have and if you substitute it in some dishes, this is the perfect side dish to enjoy and you will be saving calories without even realizing it.
Cauliflower Gratin Recipe Ingredients
Cauliflower– This tastes best with fresh cauliflower. Pick a firm cauliflower head with no bruises or dark spots. This recipe can also be made with frozen cauliflower.
Milk - I used heavy cream, but you can use a mixture of half cream and half milk for this recipe
Butter -
Cheese – I like to use Cheddar cheese, but you can mix it up with some Fontina, gruyere cheese or Parmesan cheese.
Bacon – I’m partial to low-sodium bacon as I feel it has enough salt in it. You can also use turkey bacon if you wish.

Delicious! We're hosting this year! Well, by "hosting," I mean just the five of us (whoa, five now) and Cassidy's mom and her husband. They live in a small town without even a stoplight and have zero cases of COVID and he's totally high risk so we feel safe with them in our bubble. Still a weird year, though.
Needs delicious recipes like this! And Cassidy is low carb.
