How To Make Broccoli and Cheese Casserole

For a new twist on broccoli casserole, this recipe doesn’t disappoint!

  2. Combine cream cheese, heavy cream, egg, a third of the shredded cheddar, and 1 tablespoon of the Parmesan cheese.
  3. Place the broccoli in the prepared casserole dish and stir in the cheese mixture.
  4. Cover with remaining cheese and bake until the top is golden brown and bubbly.

Recipe Tips and Tricks

  • Make your own herbed cream cheese by combining room temperature cream cheese with a savory blend of dried garlic, parsley, and onions. Or experiment with dried rosemary, basil, even a pre-made dressing blend like low carb ranch or keto taco seasoning!
  • Make this casserole ahead and keep it covered in the refrigerator when it’s ready to be reheated under the broiler for about 5 minutes.
  • Freeze broccoli casserole by preparing it in an aluminum foil lined casserole dish. Overlap the dish with 6 inches of aluminum foil on both horizontal sides. When the dish has been cooked and cooled, cover and freeze. Once frozen, carefully lift the casserole out of the dish and double wrap with the date labeled on the outside.
  • Leftovers can easily be kept covered in the refrigerator for up to 4 days. Reheat under the broiler or in the microwave.
