Ingredients
  

  • Chicken: 1.5 pounds boneless, skinless chicken thighs (or breasts), cut into bite-size pieces
  • Tamari or soy sauce: 1/3 cup (use tamari for gluten-free)
  • Coconut aminos (optional): 2 tablespoons for added sweetness and depth (reduce sweetener slightly if using)
  • Granulated keto sweetener: 2–3 tablespoons (erythritol, allulose, or a blend)
  • Rice vinegar: 1 tablespoon (unseasoned)
  • Sesame oil: 1–2 teaspoons
  • Fresh ginger: 1 tablespoon, finely grated
  • Garlic: 3 cloves, minced
  • Fish sauce (optional): 1/2 teaspoon for umami
  • Xanthan gum: 1/4 teaspoon (for thickening)
  • Avocado oil or olive oil: 1–2 tablespoons for sautéing
  • Green onions: 2–3, thinly sliced
  • Sesame seeds: 1 teaspoon for garnish
  • Red pepper flakes: Pinch for heat (optional)
  • Cauliflower rice or steamed low-carb veggies: For serving

Method
 

  1. Prep the chicken: Pat chicken dry with paper towels and cut into bite-size pieces. Season lightly with salt and pepper.
  2. Make the sauce: In a bowl, whisk tamari (and coconut aminos if using), sweetener, rice vinegar, sesame oil, ginger, garlic, and fish sauce. Taste and adjust sweetness to your liking.
  3. Heat the pan: Add avocado oil to a large skillet over medium-high heat. When shimmering, add the chicken in a single layer without crowding.
  4. Sear the chicken: Cook 5–7 minutes, stirring occasionally, until the edges are browned and the chicken is cooked through. Remove excess liquid if the pan gets watery.
  5. Add the sauce: Pour the sauce over the chicken and bring to a gentle simmer. Reduce the heat to medium.
  6. Thicken: Sprinkle xanthan gum evenly over the sauce while stirring. Start with 1/8 teaspoon, wait 30 seconds, then add more if needed. The sauce should turn glossy and coat the chicken.
  7. Finish: Stir in half the green onions and a pinch of red pepper flakes if you like heat. Simmer 1 more minute to meld flavors.
  8. Serve: Spoon over cauliflower rice or steamed broccoli. Garnish with remaining green onions and sesame seeds.
