Tender zucchini becomes a standout accompaniment when quickly cooked with fragrant onions and coated in rich Asian-style sauces. This Japanese-inspired zucchini packs amazing flavor in just minutes of cooking, making it great for hectic evenings or fancy get-togethers. The wonderful mix of umami-packed soy, sweet teriyaki, and mild spiciness creates a veggie dish that wins over even the pickiest eaters.

I came up with this cooking technique during a summer when my garden gave me way too many zucchinis and I got bored with my usual recipes. After trying different flavor combinations, this Asian-inspired version quickly became the family's top pick. My kids, who normally turn their noses up at green stuff, actually ask for seconds when I make zucchini this way.

Basic Ingredients

  • Zucchini: Forms the base with its subtle taste and sponge-like ability to soak up flavors—grab medium ones with bright, unmarked skin for the best results.
  • Sweet onion: Adds wonderful aroma and natural sweetness that browns lightly while cooking—its gentler taste works perfectly with the light zucchini flavor.
  • Teriyaki sauce: Brings sweet and savory notes that completely change ordinary veggies into something special—look for brands with visible spice flecks for better flavor.

Cooking Steps

Getting Veggies Ready:
Give your zucchini a good rinse then cut off the ends and throw them away. Slice each zucchini into two-inch chunks to make them easier to handle. Take each chunk and cut it into six wedges by cutting in half first, then slicing each half into three equal pieces.
Perfect Sautéing:
Get your oil hot in a big pan until it looks shiny but isn't smoking. Toss in your cut-up zucchini and onions, spreading them out so they brown rather than steam. Let them cook without stirring too much so they can get some nice color.
Adding Sauces:
Drizzle your sauces right over the partly-cooked veggies, which makes steam that helps the flavors sink in everywhere. Sprinkle seasonings on top, making sure they're spread all over the cooking food.
Watching Doneness:
Keep an eye on things during the last few minutes, poking zucchini with a fork to check when they're just right. Take the pan off the heat while the zucchini is still a bit firm since it'll keep cooking for a minute after.
Serving:
Put your finished dish on a serving plate or individual dishes right away while it's hot. Scatter toasted sesame seeds on top to make it look pretty with color contrast and add a light nutty flavor.

When my neighbor dropped by during dinner one night, she told me she didn't think zucchini could ever taste exciting. After trying this dish and going back for more, she asked me how I made it, saying the sauce combo completely changed her mind about this summer veggie.

Keeping Leftovers

Any extra zucchini can go in an airtight container in the fridge for up to three days. When you want to eat it again, warm it up gently in a pan on medium heat to keep it from getting too soft, which happens if you use the microwave.

Frequently Asked Questions

→ Can I prep this ahead of time?
Yes, but zucchini's best when freshly cooked. If you make it in advance, shorten the cooking time a little since the zucchini softens as it sits. Warm it gently before serving.
→ What pairs well with it?
It’s a great match for grilled chicken, teriyaki beef, or salmon. Serve with rice, noodles, or alongside egg rolls or dumplings for a complete meal.
→ Can I swap the vegetables?
Definitely! Try adding peppers, mushrooms, broccoli, or snap peas. Just adjust the cooking time—start harder veggies like broccoli earlier, and toss in faster-cooking ones like mushrooms later.
→ What if I don’t have teriyaki sauce?
No worries! Mix soy sauce with a little honey or sugar and a small pinch of garlic powder for a quick substitute. Oyster or hoisin sauce works too, but use less since they’re stronger.
→ How do I know the zucchini’s ready?
It should be soft enough to pierce easily but still keep some firmness. The color shifts from bright green to slightly see-through. Cooking it for about 6-7 minutes should make it just right.

Ingredients

→ Veggies

01 1 medium sweet onion, roughly diced
02 3 average-sized zucchini

→ Sauce Mix

03 2 tablespoons teriyaki sauce
04 1 tablespoon soy sauce
05 2 tablespoons cooking oil

→ Spices

06 1 teaspoon sesame seeds (toasted)
07 1/4 teaspoon ground black pepper
08 1/4 to 1/2 teaspoon crushed chili flakes, adjust how spicy you like it

→ Extras (Optional)

09 1 tablespoon butter to make it richer

Instructions

Step 01

Cut each zucchini into 2-inch sections, then split those into 6 wedges. This will make bite-sized pieces that soak up all the tasty sauces.

Step 02

Heat your cooking oil in a big nonstick pan on medium-high until it glimmers. This sets the stage for your stir-fry.

Step 03

Toss the zucchini and onion into your heated skillet, let them crackle and cook until they just start to soften, about 2 minutes.

Step 04

Mix in the teriyaki sauce, soy sauce, chili flakes, and black pepper. Watch as it caramelizes and turns into a shiny coating for the vegetables.

Step 05

Keep stirring now and then for another 4-5 minutes. Cook until the zucchini is as soft or crisp as you'd like.

Step 06

Turn off the heat, sprinkle sesame seeds on top, and stir in a little butter if you're feeling it. It'll add a lovely nutty crunch and more glossy richness.

Notes

  1. Goes great with grilled chicken, fish, or fluffy steamed rice.
  2. Want a heartier dish? Toss in tofu, shrimp, or chicken while cooking.
