This cheesy cauliflower casserole is the perfect side dish for your Thanksgiving feast! This creamy dish also makes a great swap for mashed potatoes if you’re doing low-carb! Top with your very own homegrown green onions!



  • 1 head of cauliflower, chopped into florets
  • ½ cup heavy cream
  • 1 cup shredded cheese (I used a mix of Colby and Monterey Jack)
  • 2 tbsp unsalted butter
  • ¼ cup sour cream
  • ¼ cup parmesan cheese
  • 2 garlic cloves, minced
  • ½ cup green onions, chopped
  • 1 tsp sea salt
  • 1 tsp fresh ground black pepper



  1. Preheat oven to 400 degrees
  2. Wash cauliflower and chop into florets
  3. Add florets to large pot and add 2 - 3 cups of water, bring to a boil
  4. When cauliflower is fork-tender, remove from heat and strain out water
  5. Return florets to the pot, and with heat on low, stir in heavy cream, parmesan cheese, sour cream, butter, and minced garlic
  6. Using a potato masher, carefully mash the cauliflower in the pot while combining ingredients
  7. Turn heat to medium-high, stir occasionally and simmer until mixture has thickened - approximately 5 minutes
  8. Remove from heat completely and transfer mixture to a casserole baking dish
  9. Bake casserole uncovered for 15 minutes or until edges are lightly browned
  10. While casserole is baking, clean and prepare your green onions
  11. Remove casserole from oven and sprinkle shredded cheese on top
  12. Return casserole to oven for approximately 7 - 8 minutes or until cheese is melted and lightly browned on top
  13. Garnish with fresh chopped green onions and serve with a dollop of sour cream if desired!
