Whole Roasted Cauliflower Tandoori is an easy 1-pot dinner that's full of spicy North Indian flavors. Just 10 minutes of prep, and the oven or slow cooker do the rest.
Preheat the oven to 400 degrees Fahrenheit. (See notes for slow cooker option.)
Line a Dutch oven or oven-proof pot (not too large) with with parchment paper. (See notes.)
In a small bowl, whisk together the yogurt, ginger, garlic, lemon and tandoori spice.
Place the cauliflower in the center of the pot, and pour the tandoori yogurt sauce over the top. (Don't be afraid to use all or most of the sauce!) Use a marinade brush or your hands to make sure the entire head is well covered with sauce.
Surround the cauliflower with the diced potatoes. It's okay to add the peas now if you like, but they will become quite well done. I like to add them at the last 5 minutes of cooking, and then broil them with the rest of the dish.
Place the pot in the center of the oven and bake for 45-50 minutes, or until the cauliflower and potatoes are tender. Add the peas after about 40 minutes if you didn't do so earlier.
If desired, remove the lid and broil on high for 3-5 minutes, or until golden brown. Make sure your pot is safe at high cooking temperatures; if not, transfer to another dish for broiling. (DON'T broil in a glass dish!)
Serve with wedges of fresh lemon (or finish with a squeeze of fresh lemon.) Don't skip this--it absolutely elevates the dish.
Notes
For a yogurt free option, use aquafaba--the liquid from canned or cooked chickpeas.
To cook in a slow cooker, line with parchment paper and cook on high for 3-3.5 hours or low 4.5-5 hours. To broil after cooking, carefully transfer the cauliflower, potatoes and peas to a broiler safe baking dish (not glass!), and broil on high for 3-5 It's best to use a Dutch oven or pot just large enough to fit your ingredients. (Like the one pictured.) If it's too large, the veggies could get dry. To cut your parchment paper to the right size, place the lid of your pot on the paper, draw a circle around it and cut it out. This should be just a little bigger than the bottom of the pot.
