  • 1 large head of cauliflower
  • ¼ cup + 2 tbsp vegetable broth
  • ½ of a red onion diced
  • 3 cloves garlic minced
  • 2 sweet bell peppers diced (I used 1 red and 1 orange)
  • 1 ½ cups + 1 tbsp fresh squeezed orange juice
  • 4 tablespoons soy sauce or tamari use wheat-free tamari for gluten-free
  • 3 tablespoons pure maple syrup
  • 3 tablespoons rice wine vinegar
  • 2 tablespoons cornstarch
  • 2 tablespoons water or more juice
  • Sesame seeds for garnish if desired
  • Cooked Rice for serving


  • Preheat the oven to 450°F.
  • Cut the cauliflower into large bite size florets. In a medium bowl toss the cauliflower with 1 tablespoon juice.
  • Place the cauliflower in one even layer on a rimmed baking sheet and bake for 15 minutes, (Add an additional 5 minutes if desired, but I like mine to still have a crunch). Cauliflower should be just browning on the edges.
  • While the cauliflower is roasting, whisk together the orange juice, soy sauce, maple syrup, and vinegar. Set aside.
  • Stir together the cornstarch and water until smooth and set aside.
  • Add ¼ cup vegetable broth to a large pan over medium heat. Add the onion and garlic and sauté 5 to 6 minutes until soft.
  • Add another 2 tbsp vegetable broth to the pan and add the peppers. Sauté 5 to 6 minutes until softened.
  • When the peppers are softened, add the orange sauce to the pan and turn up the heat to bring to a boil.
  • Once boiling, add the cornstarch/water mixture and stir well to incorporate. Simmer over medium heat until the sauce reduces and thickens to almost a syrup like consistency.
  • Add the cauliflower to the sauce when it's done roasting and stir to coat well.
  • Sprinkle sesame seeds over the top, if using, and serve immediately by itself or over rice.


~Fresh squeezed juice will give the best flavor in this recipe. Store bought juice will work in a pinch, but know that the orange flavor won't be as vibrant.
