Why I love this recipe

  • Low Carb: The main ingredient in keto broccoli casserole is broccoli, which is a low-carb vegetable. This makes it an excellent option for those looking to maintain a low-carb lifestyle while still enjoying a delicious and satisfying meal.
  • High in Healthy Fats: Keto broccoli casserole is typically made with cream cheese, heavy cream, and cheddar cheese, which are all high in healthy fats. These fats help keep you full and satisfied for longer, making it easier to stick to your keto diet.
  • Nutritious: Broccoli is a nutrient-dense vegetable that is rich in vitamins and minerals, including vitamin C, vitamin K, and potassium. Adding broccoli to your diet can help support overall health and well-being.
  • Versatile: Keto broccoli casserole is a versatile dish that can be customized to suit your taste preferences. You can add bacon, mushrooms, chicken, or other ingredients to make it your own.
  • Vegetarian. This is a vegetarian version of our keto broccoli, chicken, and cheese casserole that is so popular. It s not just for vegetarians; I eat it on its own or as a side with steak and other meat or for meal prep.

Overall, keto broccoli casserole is a delicious and nutritious dish perfect for those following a ketogenic diet.

Ingredients and substitutions

  • Broccoli. We use fresh broccoli, but frozen broccoli works well. Ensure you drain and remove as much water from the broccoli as possible.
  • Cream cheese. Only use full-fat cream cheese.
  • Heavy cream.
  • Butter. Salted. We like to use grass-fed butter.
  • Garlic. Fresh garlic is essential to give the sauce its brilliant flavor. Swapping it out for the jarred minced garlic will work, but the taste is slightly different.
  • Salt. We use iodized table salt, but any salt will do.
  • Black pepper. Ground.
  • Cheddar cheese. Grated. The sharper the cheese, the better.

    I made this in the crockpot and I have to say it was the best broccoli casserole ever! I doubled the recipe and used uncooked frozen broccoli and chopped up the cream cheese and mixed it all together in the crockpot and cooked it on high for 3-31/2 hours. The broccoli ended up perfectly cooked and was very flavorful!

    This is the best cheese broccoli I have ever had and my 6 yo LOVED it. He kept asking for more. I will definitely make this again. I would recommend this recipe if you are looking for something creamy to do with your broccoli.
    The flavor is amazing.

    Thank you!
