Cauliflower Stuffing Recipe Notes And Tips

• Make sure the cauliflower is cut into bite size pieces. This will ensure more even cooking. Also, bite-size pieces are easier to serve and eat.

• Regular or lite sour cream will work best in this recipe. Fat free will not provide the creaminess and that regular or lite will.

• Want a healthier alternative? Substitute Greek Yogurt for the sour cream.

• Frozen cauliflower florets will work, but it would be best to use fresh cauliflower. Frozen cauliflower will contain more water which may make the stuffing a little more watery.

• Be sure to add salt and pepper to taste. The recipe does not call for it but you may find that you need some added salt and pepper that doesn’t come from the other ingredients.

Variations Of Cauliflower Stuffing Casserole To Try

• In addition to the cauliflower, add some extra vegetables such as onions, celery and mushrooms. I would saute them in butter to make them a little more tender before adding them to the stuffing mixture.

• Add in some crumbled sausage or bacon to give the stuffing a little more zip.

• Sprinkle some shredded cheese over the top of the casserole before baking. I would not cover it with cheese, just a light sprinkling to give it some color and a little extra flavor.

• If walnuts are not your preference but you would like like to add in some nutty flavor, think about adding in pine nuts, pecans, hazelnuts or macadamia nuts.

• For a completely vegetarian version, feel free to substitute vegetable Better Than Bouillon instead of the chicken version.

Can I make the Cauliflower Stuffing ahead of time?

The stuffing is perfect to make ahead of time! Prepare it the day prior, then on Thanksgiving or Christmas re-heat it at 350 degrees just before serving.

Just kidding. If you happen to be fortunate to have any leftovers to enjoy again later, they will keep for up to 3 – 4 days in the refrigerator.

Can I freeze the Cauliflower Stuffing?

Definitely! You will need to let the stuffing dish cool completely in the refrigerator. Then you will need to place the stuffing you wish to freeze in a freezer bag or freezer-safe container.

Write the date and the name of the contents on the bag or the container. This will help you keep track of what you froze and how long it has been in the freezer.

You can re-heat the stuffing in the microwave at 50% until you reached the desired temperature. Or you can reheat in the oven at 350 degrees.
