How to make smoked cauliflower
- Make the garlic butter by combining softened butter, minced garlic, salt, black pepper, and onion powder. Chill in the fridge for 20 minutes or the freezer for 10 to firm up.
- Trim the cauliflower: remove excess leaves and trim the stalk slightly so the head sits flat, but keep it whole.
- Preheat the smoker to high, roughly 400–450°F. Temperatures vary by smoker—adjust as needed.
- Bring broth and water to a boil, then carefully add the whole cauliflower to blanch for 10 minutes. Drain and transfer to paper towels to cool briefly.
- Slice or break the chilled garlic butter into pieces and work them into the cauliflower’s florets and crevices. Rub any remaining butter over the head.
- Set the seasoned cauliflower on foil or a baking pan and place it in the hot smoker. Smoke for about 30 minutes, or until a fork pokes in easily and the cauliflower is tender. Remove, sprinkle with freshly grated Parmesan and chopped parsley, and serve.

Prepare the garlic butter and chill to firm it up for easier spreading.

Blanch the cauliflower in boiling water and broth for 10 minutes to infuse flavor and slightly tenderize.

Insert butter pieces between florets and rub the rest over the surface for even seasoning.

Smoke the cauliflower about 30 minutes or until tender. Finish with Parmesan and parsley before serving.

Tips and frequently asked questions
- Blanching in broth adds flavor. Use vegetable broth to keep the recipe vegetarian, or chicken broth for additional richness.
- Don’t over-trim the stalk. Leave enough of the base so the cauliflower remains whole and sits flat when cooking.
- Use freshly grated Parmigiano-Reggiano if possible. A block of high-quality Parmesan grated fresh melts and adds a bright, salty finish.
- Don’t have a smoker? You can follow the same steps and roast in the oven at about 415°F. Add 1 teaspoon smoked paprika to the butter for a smoky note and bake 25–30 minutes until tender and lightly golden.
- This recipe is naturally gluten-free and can be made Whole30 compatible by swapping butter for ghee. It’s also a good fit for many low-carb or keto menus depending on portioning.

Smoked Cauliflower
Priscilla Lawrence
Equipment
-
small bowl
-
large pot
-
strainer spatula
-
paper towels
-
foil
-
smoker (or oven if substituting)
Ingredients
- 1 cauliflower large, whole
- 1 quart broth vegetable or chicken
- 3-4 quarts water or enough to fill pot about 2/3 full
For the garlic butter
- 4 tablespoons butter softened, salted
- 3-4 cloves garlic minced
- ¼ teaspoon salt to taste
- ¼ teaspoon black pepper to taste
- 1 teaspoon onion powder
- 2 tablespoons fresh Parmesan grated
- 1 tablespoon fresh parsley finely chopped
Instructions
-
Combine softened butter, minced garlic, salt, pepper, and onion powder in a small bowl. Mix well, then chill in the freezer 10 minutes or fridge 20 minutes to firm.
-
Preheat the smoker to about 400–450°F (or preheat your oven to 415°F if roasting).
-
Trim the outer leaves and a bit of the stalk so the cauliflower sits flat, keeping the head intact.
-
In a large pot, bring broth and water to a boil. Carefully add the whole cauliflower and simmer for 10 minutes. Remove and let drain on paper towels to cool for a few minutes.
-
Cut the chilled butter into strips and press pieces into open florets, then rub the remaining butter over the whole cauliflower.
-
Place the cauliflower on foil or a baking pan and cook in the smoker for about 30 minutes, covered. When tender, remove and top with freshly grated Parmesan and chopped parsley. Serve warm.
Notes
- Water amount depends on pot size. Fill the pot to about two-thirds full so the cauliflower is mostly immersed; it may float slightly and that’s fine.
- Fresh Parm is worth it. Freshly grated Parmigiano-Reggiano yields the best texture and flavor.
- Servings vary. A large cauliflower typically serves 2–4 people depending on portions.
