Orange cauliflower is a weeknight meal sure to spark rave reviews from your loved ones– plus this sneaks some good-for-you turmeric in the mix! T-minus 30 minutes until your next delicious dinner.



For the cauliflower:

  • 1 medium head of cauliflower, chopped into equally sized 2-3″ pieces
  • 1 tablespoon olive oil 
  • salt and pepper to season

The sauce: (For keto option, see notes section below!)

  • 1 cup orange juice + the zest (35 oranges depending on size, skip zesting if using bottled OJ)
  • 3 tablespoons rice vinegar
  • 3 tablespoons sweetener ( sugar, honey, or maple syrup)
  • 1” fresh ginger finely grated or 1 teaspoon powdered ginger
  • 2 teaspoons soy sauce or coconut aminos
  • 2 teaspoons ground coriander
  • 1 teaspoon turmeric (more if you’re up for it!)
  • 2 tablespoons sesame oil
  • 2 tablespoons cornstarch + 2 tablespoons water to thicken


  1. Preheat the oven to 400F and prepare the cauliflower head. Remove the leaves and cut cauliflower into equally sized florets, about 2-3″ in size. Equally sized pieces help the cauliflower cook evenly. Toss the florets with 1 tablespoon oil and a pinch of salt and pepper in a mixing bowl.
  2. Lay the cauliflower out in a single layer on a sheet pan, preferably with the flat knife-edge touching the pan for better browning. Roast for 15 minutes.
  3. While the cauliflower is roasting: start cooking rice or quinoa or prepare a bed of greens to serve the cauliflower on.
  4. For the sauce: If using fresh oranges, zest the oranges then juice them, straining the seeds. If using fresh ginger, peel the 1″ knob of ginger and grate it on a microplane.
  5. Add the orange juice, zest, and ginger to a pot on the stove. Add vinegar, soy sauce, ground coriander, turmeric, sweetener, and sesame oil and stir to combine. 
  6. Heat over medium heat until boiling. While the sauce is heating up, make the cornstarch slurry: stir 2 tablespoons cornstarch into 2 tablespoons water in a cup or small mixing bowl. Set aside.
  7. When the sauce comes to a boil, reduce heat to low. Stir the corn starch slurry once more as it can separate, then add to the sauce stirring well to combine. The sauce will thicken within 1-2 minutes. Cover and turn off the heat.
  8. When cauliflower is done, run a spatula underneath all florets to loosen them from the baking sheet. Drizzle half of the sauce over the cauliflower florets and gently mix to combine. This recipe makes about 1 cup of sauce, which may be more than you need based on the size of your cauliflower head and your preferred ‘sauce’ level.
  9. Spoon your orange cauliflower over rice, quinoa, or mixed greens and top with other veggies/ pickled veggies, cashews, sesame seeds, or your preferred garnishes!


For the keto option:

  • 1 cup lemon juice + the zest (4-6 lemons depending on size, skip zesting if using bottled juice)
  • 3 tablespoons rice vinegar
  • 5 tablespoons keto sweetener (or more to taste)
  • 1″ fresh ginger finely grated or 1 teaspoon powdered ginger
  • 2 teaspoons soy sauce or coconut aminos
  • 2 teaspoons ground coriander
  • 1 teaspoon turmeric 
  • 2 tablespoons sesame oil

Add all ingredients to a shallow, 10-12″ pan, preferably a cast iron pan as this works well to reduce sauces. Heat the sauce to boiling, then reduce to a high simmer stirring occasionally. Watch the sauce closely– as it reduces down you’ll need to lower the heat to maintain a simmer. It will take from 10-20 minutes to thicken appropriately.

** If you fall a bit short on orange juice from fresh oranges, juice and zest them and sub water for any remaining portion needed to reach 1 full cup.

** If using bottled orange juice you may not need as much sweetener as bottled orange juice usually has added sugar.

** If after thickening the sauce and a final taste you find you want to add more sweetener you can as long as it’s a liquid sweetener so it will dissolve into the sauce.
