Ingredient Notes

- 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.
