Equipment You’ll Need

• Large stockpot (for blanching)
• Large mixing bowl
• Whisk
• Paring knife
• Rimmed baking sheet
• Parchment paper or silicone baking mat
• Pastry brush (optional, for basting)

Ingredients

• 1 large head of cauliflower (about 2-2.5 lbs)
• 1 cup plain, unsweetened thick vegan yogurt (coconut or soy-based work well)
• 3 tablespoons avocado oil or other neutral high-heat oil, divided
• 3 tablespoons fresh lemon juice
• 2 tablespoons ginger-garlic paste
• 3 tablespoons tandoori masala powder
• 1 tablespoon Kashmiri red chili powder (for color, less heat)
• 1 teaspoon garam masala
• 1 teaspoon ground turmeric
• 1.5 teaspoons salt (or to taste)
• 1/2 teaspoon black pepper
• Fresh cilantro, chopped, for garnish
• Lemon wedges, for serving

Instructions

1. Prepare the Cauliflower: Bring a large stockpot of salted water to a boil. Wash the cauliflower and trim the outer leaves, leaving the stem intact so the head stays whole. Carefully lower the cauliflower into the boiling water and blanch for 5-7 minutes. This step helps to tenderize the center. Carefully remove the cauliflower and place it on a wire rack to drain and cool completely. Pat it thoroughly dry with paper towels; a dry surface is crucial for the marinade to adhere properly.
2. Create the Tandoori Marinade: In a large mixing bowl, combine the vegan yogurt, 2 tablespoons of oil, lemon juice, ginger-garlic paste, tandoori masala, Kashmiri red chili powder, garam masala, turmeric, salt, and black pepper. Whisk until you have a smooth, thick paste.
3. Marinate the Cauliflower: Once the cauliflower is completely cool and dry, place it in the bowl with the marinade. Using your hands or a spatula, generously coat the entire surface of the cauliflower, making sure to push the marinade into all the crevices between the florets. Lift the cauliflower and spread marinade on the bottom and stem as well.
4. Let it Rest: Cover the bowl and refrigerate for at least 1 hour, but for the best flavor, let it marinate for 4-8 hours or even overnight. This allows the spices to deeply penetrate the cauliflower.
5. Preheat and Prepare for Roasting: When ready to cook, preheat your oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper. Place the marinated cauliflower stem-side down on the prepared sheet.
6. Roast to Perfection: Drizzle the remaining 1 tablespoon of oil over the cauliflower. Roast for 45-60 minutes, or until the cauliflower is tender all the way through (a knife inserted into the center should meet little resistance) and the exterior is beautifully charred in spots.
7. Rest and Garnish: Let the roasted cauliflower rest for 5-10 minutes before carving. Garnish generously with fresh chopped cilantro.
8. Serve: Carve the cauliflower into wedges and serve immediately with lemon wedges on the side for squeezing over.

Expert Cooking Tips

• Don’t Skip the Blanching: Blanching the cauliflower first is key to ensuring the inside is perfectly tender by the time the outside is beautifully roasted and caramelized.
• Dry is Key: Ensure the cauliflower is patted completely dry after blanching. Any excess water will thin out the marinade and prevent it from sticking, resulting in a less flavorful crust.
• Use Thick Yogurt: The consistency of your marinade is important. Use the thickest vegan yogurt you can find. If your yogurt is thin, you can strain it through a cheesecloth for an hour to remove excess water.
• Marination Matters: While you can get away with a 1-hour marinade, letting it sit for several hours or overnight will make a world of difference in the depth of flavor.

Substitutions and Variations

If you are not vegan, full-fat Greek yogurt is an excellent substitute for vegan yogurt. For the ginger-garlic paste, you can use 1 tablespoon of freshly minced ginger and 1 tablespoon of freshly minced garlic. If you don’t have tandoori masala, you can make a blend using paprika, cumin, coriander, turmeric, and cayenne pepper.

Common Mistakes to Avoid

A common mistake is not getting the marinade into all the nooks and crannies. Be thorough and use your hands to really work the paste between the florets. Another pitfall is under-roasting; the cauliflower should be fork-tender all the way to the core. Test it with a paring knife. Finally, avoid using a low-fat or thin yogurt, as the marinade will be runny and won’t form a nice crust during roasting.

Serving Suggestions

Serve this whole roasted tandoori cauliflower as a stunning main course alongside saffron rice, cooling cucumber raita (use vegan yogurt), and a simple kachumber salad (diced cucumber, tomato, and onion). It’s also fantastic served with warm naan bread or a low-carb equivalent. For a complete meal, pair it with a simple lentil dal.

Storage and Reheating Tips

Store leftover cauliflower in an airtight container in the refrigerator for up to 3 days. To reheat, place it on a baking sheet in a 350°F (175°C) oven for 10-15 minutes, or until warmed through. This method helps to crisp up the exterior again, which is preferable to microwaving.

Frequently Asked Questions

Can I make this on the grill?

Yes, absolutely! For a smokier flavor, you can cook this on a grill. Place the marinated cauliflower on indirect heat and close the lid. Cook for 40-50 minutes, or until tender, turning occasionally. You may want to place it on a piece of foil to prevent sticking.

Is this recipe very spicy?

The heat level can be adjusted. Kashmiri red chili powder is used primarily for its vibrant color and is quite mild. For more heat, you can add 1/2 to 1 teaspoon of cayenne pepper or a finely chopped green chili to the marinade.

Can I use individual cauliflower florets instead of a whole head?

Yes, you can. The cooking time will be significantly shorter. Toss the florets in the marinade and roast at 400°F (200°C) for 20-25 minutes, tossing halfway through, until tender and slightly charred.
