Far from the typical bland roasted cauliflower recipe you may have tried this recipe is tangy and full of rich flavor, thanks to the delicious sauce.

While the ingredients are basic, the result is delicious. This delicious vegan appetizer dish is made by roasting a cauliflower in the oven in a creamy Thai green curry sauce served with zucchini.

By cooking the cauliflower in the oven, you get a nice and crispy exterior while the interior is cooked just right and topped with a delicious and savory creamy sauce.

This easy and delicious recipe is perfect for a vegan or vegetarian meal, and it’s also dairy free so it’s great for anyone looking for a plant-based and delicious dish.

I love the way cauliflower can be transformed into such a delicious and healthy dish, and I know that you will too!

How to Make the Best Whole Roasted Cauliflower

Add the olive oil to casserole pan with lid (that can be used in the oven) and sauté the onions and garlic for two to three minutes after the oil is heated.

To the casserole add the coconut milk, bay leaves, Dijon mustard, pomegranate molasses, lemon juice, green curry paste and water Once it boils cook it at a simmer for 5 to 6 minutes.

Then dice the leftover stem and set aside. Nothing will be wasted!

Place the cauliflower head into the casserole and use a soup ladle to pour the sauce over the cauliflower, being sure to cover all of it. Then shift the cauliflower face down into the casserole. Turn over (right side up) and top with sauce. Add the zuchhini slices onto one side inside the casserole and make sure the sauce is thoroughly coated as well.

The casserole should be covered with a lid and cooked in the oven for one hour. At the halfway point (after 30 minutes), take the zucchini and place it into a separate bowl so that it doesn’t overcooking. Reuse the soup ladle to mix the sauce into the food. With the soup ladle coat the cauliflower with the sauce.

Once the 1 hr is up, activate the upper grill and roast for a further 2–3 minutes to achieve that lovely, crispy golden exterior. Serve with the zuchinni.

  • 2 tbsp olive oil
  • 1 small onion
  • 2 garlic cloves (finely chopped)
  • 1 can full fat coconut milk (400 ml)
  • 2 bay leaves
  • 1 tbsp French Dijon Mustard
  • 1 tbsp pomegranate molasses
  • 1 tbsp lemon juice
  • 1 tsp green curry paste
  • ¼ cup water
  • 1 big cauliflower
  • 1 medium zuchinni
  • 3 tbsp roughly chopped basil


  • Heat the oven to 400°F (200°C)
  • In a casserole with lid (or oven safe sauté pan) add the olive oil to medium-high heat. Once hot, add the onions and garlic and sauté for 2-3 mins.
  • Add the coconut milk, bay leaves, Dijon mustard, pomegranate molasses, lemon juice, green curry paste and water to the casserole. Once it simmers cook for 5-6 minutes until it starts to get thicker.
  • Slice the zucchini into round 1 inch slices. Set aside. Cut the stem off the whole cauliflower head so it lays flat. Instead of discarding, dice the leftover stem and set aside. We will add it into the casserole later.
  • Add the cauliflower into the casserole face down and use a soup ladle to pour over the sauce, make sure you get it everywhere. Flip over (right side up) and pour the sauce to cover. Now push the cauliflower to one side, and add your zucchini slices and diced cauliflower stem. Make sure these are also coated with the sauce.
  • Cover the casserole with a lid and cook covered in the over for 1 hr. Halfway in (at 30 mins) remove the zucchini and set aside in a separate bowl (to avoid overcooking). Use the soup ladle again to immerse with the sauce.
  • Once done, turn on the upper grill and roast for 2-3 mins until you get a nice crispy gold layer. Remove from the oven. Carve the cauliflower into thick pieces and serve with the zucchini slices.
