Servings 6 people as a side


  • 1 lb broccoli, cut into florets about 4 1/2 cups
  • 2 tbsp grass-fed butter
  • 2 tbsp almond flour
  • 1 1/2 cups heavy cream
  • 2 cloves of garlic, minced
  • 2 tbsp cream cheese
  • 1/3 cup parmesan cheese
  • 1 cup shredded mozzarella cheese


  1. Preheat oven to 375ยบ. Bring a large pot of water to a boil. Season with salt and add broccoli. Cook until it just begins to become tender (3-4 minutes), drain well.  Pat with a paper towel and get as much moisture out of the broccoli as possible. 

  2. While the broccoli cooks - melt the butter in a sauce pan. Add the minced garlic and cook for 30 seconds until fragrant. Add the almond flour and whisk constantly, until it just begins to brown (1 minute or so). 

  3. Whisk in cream, cream cheese, salt and pepper and allow everything to incorporate. Once boiling reduce the heat to medium, stirring occasionally, until VERY thick, about 7-8 minutes.

  4. Remove the sauce from the heat and add the parmesan cheese, whisk until incorporated. 

  5. Spread 1/3 of the sauce on the bottom of a casserole dish. Pack the broccoli into the pan and spread the rest of the sauce over top. Sprinkle with the shredded mozzarella cheese

  6. Bake until golden brown and bubbly, about 25-30 minutes. OPTIONAL: broil for 2-3 minutes until golden

  7. Let stand for 5 minutes and DEVOUR!
