This Japanese Zucchini & Onion Stir-Fry is a fast, flavor-packed side dish that transforms simple vegetables into pure umami magic. Tender-crisp zucchini ribbons and sweet caramelized onions are tossed in a savory-sweet glaze and finished with toasted sesame seeds for a glossy, irresistible dish ready in just 15 minutes.

  • Total Time: 20 minutes
  • Yield: 3 servings

Ingredients

Scale
  • 2 tbsp vegetable oil or avocado oil
  • 1 medium onion, thinly sliced
  • 2 medium zucchini, cut into thin strips
  • 2 tbsp sugar-free teriyaki sauce
  • 1 tbsp soy sauce or tamari
  • 1 tbsp toasted sesame seeds
  • Ground black pepper, to taste

Instructions

  1. Heat oil in a large skillet or wok over medium-high heat until shimmering.
  2. Add sliced onions and stir-fry for 2–3 minutes until softened with lightly golden edges.
  3. Add zucchini strips in a single layer. Stir-fry for 5–7 minutes until tender-crisp, avoiding overcrowding the pan.
  4. Push vegetables to one side of the pan. Pour in the teriyaki sauce and soy sauce and let bubble for about 15 seconds.
  5. Toss everything together to coat evenly in the glaze.
  6. Season with freshly ground black pepper and cook for 1 additional minute.
  7. Remove from heat, transfer to a serving dish, and sprinkle with toasted sesame seeds. Serve immediately.

Notes

  • High heat and quick cooking are essential to prevent soggy zucchini.
  • Use sugar-free teriyaki sauce to keep this dish keto-friendly.
  • Do not overcrowd the pan—cook in batches if necessary.
  • Best enjoyed fresh, but leftovers can be added cold to salads or omelets.
