30-Minute Keto Teriyaki Chicken Skewers

Tender grilled chicken skewers coated in a rich, umami-packed teriyaki glaze made without sugar. The marinade combines soy sauce, rice vinegar, and sesame oil for authentic Japanese flavors, while sugar-free sweetener and xanthan gum create the signature glossy coating. Perfect for weeknight dinners or outdoor grilling, these skewers deliver all the savory-sweet taste of traditional teriyaki while keeping carbs low. The chicken stays juicy from marinating, and the final glaze adds beautiful caramelization.

Tips
Marinate chicken up to 4 hours for deeper flavor penetration, but 30 minutes minimum works for weeknight meals
Reserve some unmarinated sauce separately if you prefer not to use marinade that touched raw chicken for the final glaze
Watch the final caramelization step closely as sugar-free sweeteners can burn faster than regular sugar

Serve hot off the grill with cauliflower rice, grilled vegetables, or Asian cucumber salad.

FAQ
Can I make these without xanthan gum?
Yes, but the glaze won't thicken as well. You can simmer the marinade longer to reduce it naturally, though it won't be as glossy.
What if I don't have skewers?
Cut chicken into larger pieces and grill directly on grates, or use a grill basket. Cooking time may need slight adjustment.
How long will these keep in the fridge?
Cooked skewers stay fresh up to 3 days refrigerated. Reheat gently to avoid drying out the chicken.
