Total Time: 20 minutes
Servings: 3–4

Ingredients

2–3 medium zucchinis, thinly sliced (or cut into half-moons/sticks)

1 medium white onion, sliced into wedges

2 tbsp canola oil (or another neutral oil like grapeseed or sunflower)

2 tbsp thick teriyaki sauce

1 tbsp soy sauce

1 tbsp toasted sesame seeds (for garnish)

White pepper, to taste

Optional Add-ins:

1 clove garlic, minced

1 tsp fresh ginger, grated

Crushed red pepper flakes, to taste

Instructions

Prep the Vegetables:
Slice zucchini and onion evenly to ensure they cook at the same rate. If using garlic or ginger, have them ready.

Heat the Pan:
Place a large skillet or wok over medium-high heat. Add canola oil and let it heat until shimmering.

Sauté the Onion:
Add onion wedges and cook for 2–3 minutes, stirring occasionally, until slightly softened and just starting to caramelize.

Add Zucchini:
Toss in the zucchini and continue to stir-fry for another 4–6 minutes, until tender but still crisp.

Add Flavor Base:
Stir in garlic and ginger (if using) and cook for 30 seconds until fragrant.

Sauce It Up:
Pour in teriyaki sauce and soy sauce. Toss well so the vegetables are evenly coated and glossy. Cook for another 1–2 minutes until the sauce slightly thickens and clings to the veggies.

Season and Finish:
Sprinkle white pepper and adjust seasoning if needed. Remove from heat and garnish with toasted sesame seeds and optional crushed red pepper flakes.

Serve:
Enjoy hot as a side dish or serve it over rice, quinoa, or couscous for a quick meal.

Tips

High Heat Is Key: Stir-frying at high heat keeps vegetables crisp and prevents sogginess.

Avoid Overcrowding: Cook in batches if needed so veggies sear instead of steam.

Uniform Slices: Cut zucchini and onions evenly for consistent texture.

Use Thick Teriyaki Sauce: A thicker glaze-style teriyaki helps coat the vegetables beautifully.

Add Salt Carefully: Both soy sauce and teriyaki contain salt; taste before adding more.

Don’t Overcook: Zucchini should stay slightly firm—overcooking makes it mushy.

Boost Umami: Add a splash of rice vinegar or a drizzle of sesame oil at the end for complexity.

Fresh Garnish: Sprinkle sesame seeds right before serving to preserve crunch and aroma.

Variations

Mediterranean Fusion: Add cherry tomatoes and a few olives near the end for a fresh Mediterranean touch.

Spicy Version: Add chili oil or crushed red pepper for gentle heat.

Protein Add-In: Stir-fry shrimp, chicken, or tofu before adding vegetables for a more filling meal.

Creamy Twist: Top with a dollop of Greek yogurt mixed with lemon juice and herbs.

Nutty Flavor: Garnish with toasted pine nuts or crushed almonds instead of sesame seeds.

Sweet-Savory Balance: Add a teaspoon of honey or balsamic glaze for depth.

Garlic-Lovers Version: Double the garlic and add it at the end to keep its sharp aroma.

Green Boost: Add spinach or edamame in the last minute of cooking for extra color and nutrients.

Q&A

Q: Can I use olive oil instead of canola oil?
A: Yes, light olive oil works well, but avoid extra virgin since it has a low smoke point.

Q: How do I prevent zucchini from becoming soggy?
A: Cook on high heat, don’t cover the pan, and avoid adding salt early—it draws out moisture.

Q: What can I serve it with?
A: It pairs beautifully with steamed jasmine rice, soba noodles, or even Mediterranean couscous.

Q: Can I make it ahead of time?
A: It’s best fresh, but you can prep the veggies and sauce in advance, then cook just before serving.

Q: Is it gluten-free?
A: Yes, if you use gluten-free soy and teriyaki sauces.
