Creamy oven-roasted cauliflower that’s delicious by itself, but even more intriguing with a savory soy-ginger sauce. Vegan and gluten-free friendly.


Cauliflower is one of those vegetables that people sometimes don’t know what to do with. Oh, sure, you see it on the crudité table all the time, ripe for dipping. But this innocuous little garden delight has so much more to offer, and this Roasted Cauliflower with Soy-Ginger Sauce recipe is just one of many ways you can enjoy cauliflower.

Cauliflower is part of the cruciferous family, along with cabbage, broccoli, Brussels sprouts and bok choy. In case you hadn’t heard, cruciferous vegetables are heavily recommended as part of a healthy diet to help prevent cancer. It is an antioxidant and anti-inflammatory food, and is bursting with Vitamins C, K and beta-carotene.

Now, all that is wonderful, but the best part is that cauliflower takes on the flavors of things it is cooked with. That makes it ideal for this delectable Soy-Ginger sauce that is drizzled on this dish. Actually, this sauce can be drizzled, served as a side for dipping, or you can just toss the roasted cauliflower in the sauce and save everybody at the table heaps of time. Because you just know that the sauce is going to disappear!

For best results, look for cauliflower heads that are white and bright. If your cauliflower has little specks of black or brown on some of the florets, just shave those off with a vegetable peeler. They won’t hurt you, but for the sake of appearance, it’s just as easy to trim them off. By the way, to help prevent that in the future, wait until you’re about to cook or serve your cauliflower before washing it. Moisture contributes to those little imperfections.

  • Prep Time: 10 minutes
  • Cook Time: 20 minutes
  • Total Time: 30 minutes


Creamy oven-roasted cauliflower that’s delicious by itself, but even more intriguing with a savory soy-ginger sauce. Vegan and gluten-free friendly.


  • 1 medium head cauliflower (about 2 pounds)
  • 1/4 cup extra-virgin olive oil
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon ground black pepper

For The Soy-Ginger Sauce

  • 2 teaspoons sesame oil
  • 1 tablespoon minced or grated fresh ginger
  • 2 teaspoons minced garlic (about 2 medium garlic cloves)
  • 1/4 cup water
  • 2 tablespoons soy sauce
  • 1 tablespoon red wine vinegar
  • 1 teaspoon brown sugar
  • 1 stem green onion, chopped


  1. Preheat the oven to 450°F. Line a large baking sheet with foil.
  2. Trim the outer leaves of the cauliflower and cut the steam flush with the bottom of the head. Then, cut the cauliflower into florets.
  3. Combine cauliflower florets, olive oil, salt and pepper in a large mixing bowl. Toss well and lay the cauliflower, cut side down, on the prepared baking sheet in a single layer.
  4. Cover the cauliflower with foil and roast for 10 minutes.
  5. In the meanwhile, make the soy-ginger sauce. Cook the oil, ginger and garlic in a small skillet over medium-high heat until fragrant, 1-2 minutes. Reduce the heat to medium-low, stir in water, soy sauce, vinegar and sugar and simmer until the sauce is thickened, about 4-6 minutes. Transfer to a small bowl and add green onions. Set aside.
  6. Remove the foil and continue to roast the cauliflower for 10-15 minutes, or until the top of the florets are brown. If you’d like to brown both sides, flip them once halfway through the second 10 minutes of baking.
  7. Remove the cauliflower from the oven, dish and enjoy with the soy-ginger sauce.


Alternatively, you can make a spicy version with either curry powder or chili powder. Simply stir 2 teaspoons of either spice into the oil before seasoning the cauliflower in step 3.
This recipe goes very well with rice.

    1. Hi Gemma! If you don't like green onion, feel free to leave it out from this recipe. It's not a deal breaker. :)
  1. Sharon, thanks so much for your reply. Very helpful. Now maybe it's me but step 4 says this: Cover the baking sheet with foil and roast the cauliflower for 10 minutes. With all due respect shouldn't it say cover the cauliflower with foil? Anyway, thanks again. J
    1. Hey Jon! Yes, it does sound more clear if I say: cover the cauliflower with foil. I have changed it in the recipe. Thank you for your suggestion. I appreciate it. :)
    1. Hi Jon! When you roast the cauliflowers for the first 10 minutes, you want to cover them with foil. Then continue roasting for another 10-15 minutes without covering by the foil. That's what I meant by "removing the foil." Hope this helps. Feel free to let me know if you have other questions. Can't wait to hear how you like this recipe. :)
  2. Hi, Did it for lunch today and everybody loves it!! I just made some noodles (for the meal-without-meat-or-carbs-is-not-a-real-meal persons). The only differences was that i didn't have sesame oil and used sesame seeds instead. Worked perfectly. Thanks for sharing.
    1. Excellent! I am so glad to hear that. Thank you for your comment. It's good to know that sesame seeds works for the sauce as well. :) Cheers!
    1. Hi Susan! 2 tablespoons soy sauce. I missed it in the ingredient list. Thanks for asking. I've updated the recipe.
    1. Hello Cailee! I just read your post about the health benefits of cauliflower. Very well written! Looks like we have so much in common. :) XOXOXO
