Why I Love This Recipe

A few years back I was chatting with a friend about a vegetarian thanksgiving menu. We both agreed that the whole head of roasted cauliflower looked very pretty, but was not excited about the steamed cauliflower taste. That was what most of the recipes taste like. The crispy tops of the florets might look and taste great the insides were definitely not!

I wanted to spice it up a bit, but – and that is a big BUT – still wanted to do it in a short time. The first thing that came to mind was a sauce – this dish needs a sauce. As the marinade was inspired by Tandoori flavors, cilantro sauce became the perfect complement.

Easy to Make

Making this dish can be broken down to

  • Prep the cauliflower
  • Make marinade
  • Marinate the cauliflower
  • Roast
  • Make the Sauce

Most of the time is used for roasting. There is no stirring, mixing, or checking on things every few minutes. Did I say it was easy?

Prep the Cauliflower

Trim off any green leaves from the cauliflower. Rise and pat dry. Trim the stem close to where the florets begin to start branching off. This helps the head stay upright in the pan. Make sure there is no water trapped inside as we do not want to steam the florets.

Prepare the Marinade

The inspiration for the marinade came from the tandoori flavors- yogurt, paprika, garlic, salt, cumin, oil, and lemon juice. Add cayenne or black pepper if you want to make it spicy. This marinade is the only part that stops this dish from being vegan.

For the vegan version – substitute equal amounts of vegan yogurt, coconut cream, or almond milk in the marinade. My preference is coconut cream and a pinch of cayenne to offset the sweetness.

Apply the marinade

 Jut rub it well all around making sure that it gets into all the nooks and crannies of the cauliflower. When you cut into this you want to see the beautiful red color from the paprika seeping into the core. A pastry brush is helpful here. It gently coxes the marinade into the tiny gaps without breaking off the florets.

 Apply the marinade on both sides of the cauliflower. Start by placing the cauliflower upside down and applying the marinade from the bottom. Try to get into as many florets as you can without breaking it. Wait for a minute for it to let it run down to the top of the florets

Lightly coat the roasting pan with oil and place the cauliflower right side up in the pan. Slowly pour the marinade on top. Use a pastry brush to get the marinade into all the nooks and crannies. We are looking for a nice thick coating, so don’t be afraid to slather it on.

Roasting the cauliflower

We do not want the steamed cauliflower – so it is important to roast in a fairly hot oven.  400°F or 425°F should suffice. You don’t need any fancy equipment either. A skillet, cake pan, clay baker, Dutch oven, or anything that is big enough to hold the cauliflower and is oven safe will get the job done.

Here I have used a porcelain casserole, but you can use any oven-safe, non-reactive cookware ( the marinade is acidic). Place the lid on or cover with aluminum foil. Now it is ready for the oven.

Place the oven rack a little below the center and transfer the cauliflower to the preheated oven. Cook covered for about 30 minutes. By this time the cauliflower would have given off some juices. 30 minutes should suffice for a medium head of cauliflower, for larger ones add an extra 10 minutes. All that is left now is to brown the tops a little. If you have the broil option broil for about 10 minutes, keeping an eye on it after the 5-minute mark. Or turn the oven temperature to the maximum and bake for another 10 minutes. I burnt the tops a little – but you can do better.

Cilantro Sauce

 And for the sauce, just pulse all the ingredients together in the blender!

Don’t like cilantro – use green onions, mint or parsley.


If you are pressed for time, both the chutney and the marinade can be made a day in advance. But do not marinate the cauliflower for long periods though. The moisture and acidity will slowly break down the florets.


Take it out of the oven let it rest for a few minutes. Transfer to the serving plate. If there are pan juices drain and strain it. Taste and adjust seasoning (a dash of lemon or salt) and drizzle over the cauliflower while serving. Or you can do what I did I did here, brighten up the flavors with the cilantro sauce.
