    Broccoli Casserole is the classic casserole we love at every dinner table...now with a keto twist!

    Let's face it...at every holiday or gathering there is always that one favorite side dish!

    Now with my Keto Broccoli Casserole recipe, you can have the same classic flavor! With a healthier alternative!

    Let's get started!

    HOW TO MAKE KETO BROCCOLI CASSEROLE

    First things first! Preheat your oven to 350F.

    Spray an 8 x 8 casserole dish with cooking spray or grease with butter.

    Now combine the topping ingredients in a small bowl and set aside.

    Once you're finished with that..

    In a large skillet over medium heat, cook the onion with the butter until the onion is translucent (about 8 minutes)

    Add in the minced garlic and cook for 1 minute more.

    Now you can add in the heavy cream and cream cheese.

    Stir to melt the cream cheese.

    When the cream cheese is melted, remove from the heat and stir in the shredded cheddar.

    Your result is this dreamy cheese sauce that you will want to put on everything!

      The cheese sauce alone is great over any steamed vegetable.

      Hi Jennifer

      Would using almond milk or fat free greek yogurt help cut some calories ?

      The recipe sounds awesome but just too many calories for me

      This was the best! Everyone loved it. I’m going to make it again this weekend. Once question, could I make ahead and bake tomorrow ? Or how would you reheat it tomorrow ?

      Just made this as directed and it was SO GOOD! I just made sure to strain/dry out the cauliflower rice and broccoli a bit after steaming to make sure it didn’t make the final product watery. This will definitely be a regular at our house! YUM

      While I love cauliflower, I do not like the texture of cauliflower rice, so I made this with Miracle Noodle brand rice (shirataki noodles). I used two packs. It is soooo yummy! Thanks for a great recipe!
