Ingredient Notes

cauliflower , celery , mushrooms , butter , onion and seasonings to make Cauliflower Stuffing with labels.
  • Cauliflower: Cut fresh cauliflower into small, evenly sized pieces so it cooks quickly and develops the most flavorful, browned edges.
  • Butter: Browns the vegetables while adding the rich, savory flavor you expect from traditional stuffing.
  • Seasoning:
    • Poultry seasoning is a shortcut used to create that classic stuffing flavor. It typically combines herbs like sage, thyme, and marjoram. You can make your own poultry seasoning or use storebought.
    • Fresh parsley brightens the rich flavors, keeping the stuffing from tasting too heavy.
    • Rosemary brings a bold, herbal flavor.
    • Salt enhances all the flavors, while black pepper adds a mild heat with a peppery bite.
  • Mushrooms: White mushrooms, cremini, or baby bellas add earthy, savory flavor and make this low carb stuffing more hearty.

Variations

  • Cooked and drained low-carb sausage makes a great addition to cauliflower stuffing. 
  • Chopped pecans can be added for extra crunch.
  • For a dairy-free option, use olive oil instead of butter.
  • You can add diced zucchini or bell peppers, just be sure to not over crowd the pan.
  • Top keto cauliflower stuffing with bacon bits or shredded cheddar cheese before serving for a tasty option.

How to Make Cauliflower Stuffing

  1. Cut the cauliflower and dry it thoroughly.
  2. Combine melted butter with the herbs and seasonings.
  3. Toss the cauliflower, mushrooms, onion, and celery with the butter.
  4. Spread over a rimmed baking sheet and roast until (full recipe below).

Secrets to Golden Stuffing

  • Dry the cauliflower thoroughly before seasoning. Excess moisture creates steam in the oven, preventing the browned, caramelized edges.
  • Cut cauliflower into small, uniform pieces so everything cooks at the same rate. Pre-cut florets are a convenient shortcut when you’re short on prep time.
  • Dice the onion small so it softens properly and develops caramelized edges alongside the cauliflower.
  • Spread vegetables in a single layer so they roast and brown instead of steam. If you double the recipe, use two pans.
  • Stir the vegetables after 15 minutes so more surfaces can brown against the hot pan.
  • Season keto cauliflower stuffing to taste.
  • Roast cauliflower stuffing a few minutes longer than suggested for softer texture, or remove it as soon as the cauliflower is fork-tender for a firmer texture.

Storing Leftovers

  • Store cooled leftovers covered with plastic wrap or in an airtight container.
  • Refrigerate for up to 4 days and in the freezer for up to 1 month. Thaw overnight in the refrigerator.
  • Reheat uncovered, spread over a baking sheet to help restore some of the roasted texture, in a 350°F oven until heated through. Or reheat quickly in the microwave just know the vegetables will be softer.
