Ingredients
Servings
4
- 1 large head cauliflower (about 2 pounds), leaves removed
- 3 tablespoons olive oil, divided
- 1 teaspoon ground cumin
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
- For the Lemon-Tahini Sauce
- 1/3 cup tahini (make sure it's gluten-free)
- 3 tablespoons fresh lemon juice
- 1 tablespoon maple syrup or honey (optional for sweetness)
- 1 clove garlic, minced
- 3 to 5 tablespoons warm water (to thin sauce)
- Salt to taste
- To garnish
- Chopped fresh parsley
- Toasted sesame seeds (optional)
Instructions
-
Preheat your oven to 425 degrees F (220 degrees C). Line a baking sheet with parchment paper or a silicone mat.
-
Remove all leaves from the cauliflower and trim the stem end so it can sit flat. Slice the cauliflower from top to bottom into 3/4 to 1-inch thick 'steaks'. You should get about 3-4 steaks, with the rest of the florets loose.
-
Arrange the cauliflower steaks and any loose florets on the prepared baking sheet.
-
In a small bowl, combine 2 tablespoons olive oil with cumin, smoked paprika, garlic powder, salt, and pepper.
-
Brush both sides of each cauliflower steak and florets with the spiced olive oil mixture, ensuring they are fully coated.
-
Roast in the oven for 20 minutes, flipping the steaks halfway through, until golden brown and tender.
-
Meanwhile, prepare the lemon-tahini sauce: In a small bowl, whisk together tahini, lemon juice, maple syrup or honey (if using), minced garlic, and salt.
-
Add warm water one tablespoon at a time until the sauce reaches a smooth, pourable consistency.
-
Once the cauliflower steaks are done roasting, transfer them to a serving platter.
-
Drizzle with the creamy lemon-tahini sauce, then garnish with chopped parsley and toasted sesame seeds if desired.
-
Serve warm as an elegant holiday side dish, healthy snack, or a quick family-friendly meal addition.
Tips
Allergen Overlap Note
Tahini is sesame-based, so flag it clearly for guests with sesame allergies. Choose tahini, spices, maple syrup or honey, and sesame seeds labeled gluten-free when possible, and use clean parchment, brushes, and serving utensils if wheat breads or gluten sides are also part of the meal.
Texture Expectations
The cauliflower should roast with browned, crisp edges and a tender center that still holds together as a steak. Keep the slices thick, flip gently, and thin the tahini sauce with warm water until it drizzles smoothly without becoming watery.
Dining With Non-GF Family Note
Serve the cauliflower on its own clean platter before any regular bread or crumbly sides reach the table. Keep the lemon-tahini sauce in a dedicated bowl with a clean spoon so gluten-containing foods do not get dipped into it.
Frequently Asked Questions
- How do I keep cauliflower steaks from falling apart?
- Slice through the center stem so each steak has a sturdy core, and move the slices gently with a wide spatula when flipping.
- Can I make the tahini sauce ahead?
- Yes. Whisk it ahead and refrigerate it for up to 3 days. It may thicken as it chills, so loosen it with warm water before serving.
- What can I use instead of tahini?
- For sesame-free diners, try sunflower seed butter or pumpkin seed butter thinned with lemon juice and warm water.
Ingredient Replacements

- Maple Syrup or Honey: Use pure maple syrup to keep the recipe vegan and paleo. You may omit the sweetener entirely to reduce sugar.
- Olive Oil: Substitute olive oil with avocado oil or coconut oil for roasting to vary flavor and nutrition.
- Spices: Feel free to adjust smoked paprika and cumin amounts to taste or try turmeric, coriander, or other warming spices for new flavor profiles.
