Spicy Korean Zucchini Stir-Fry (Aehobak Bokkeum)
Spicy Korean Zucchini Stir-Fry (Aehobak Bokkeum) — Easy 25-Minute Banchan, Noodle Topper, or Rice Bowl
If you’ve ever looked at a lonely zucchini and thought, “You could be so much more,” this is the recipe. Aehobak bokkeum (애호박볶음) is a classic Korean-style zucchini stir-fry that’s lightly sweet from onion, nutty from perilla oil, and warmly spicy from gochugaru—perfect as banchan (side dish), a noodle topping, or the base for a quick rice bowl.
What is Aehobak Bokkeum?
Aehobak is Korean zucchini/summer squash (tender skin, mild flavor). Bokkeum means stir-fried. This dish is a quick sauté of zucchini, onion, scallion, and garlic, finished with gochugaru and a savory seasoning sauce.
This version is especially versatile: it works as:
- a simple rice side dish (banchan)
- a topping for bibim noodles (or even for warm noodle soups as garnish)
- a fast rice bowl ingredient (add a fried egg and call it dinner)
Why You’ll Love This Recipe:
- Super quick — only 10 minutes prep, 15 minutes cooking
- Naturally plant-based when made with vegetable oil and verified gochujang
- Gluten-free (check your soy sauce)
- Endlessly adaptable — works with rice, noodles, eggs, wraps, and more
- Packed with flavor — spicy, savory, slightly sweet, and fragrant
Ingredients
(All measurements are standard US tablespoons/spoons)
Main Ingredients
- 1/2 medium zucchini (about 150g / 5 oz), julienned
- 1/2 tsp minced garlic (about 5g)
Sub Ingredients
- 1/4 small onion (70g), thinly sliced
- 1/3 large green onion (30g), sliced diagonally
- 2 tbsp sesame oil (traditional — but regular oil works too!)
Seasonings
- 2 tbsp gochujang (Korean red chili paste — choose a brand made with chili, rice, soybeans, and salt only)
- 1 tbsp coarse Korean red pepper flakes (gochugaru)
- 1 tsp sesame oil (for finishing)
- 1 tsp toasted sesame seeds, plus extra for garnish
Pro Tip: If you can’t find gochujang, use 1 tbsp sriracha + 1 tsp maple syrup as a substitute (though real gochujang gives the authentic fermented depth).
Step-by-Step Instructions
Step 1: Prep Your Veggies (10 Minutes)
- Wash the zucchini and cut it into thin matchsticks (julienne) — about 2-3 inches long.
- Peel and thinly slice the onion.
- Slice the green onion into 1-inch pieces — whites and greens separated is ideal, but not required.
Save time: Use a mandoline or food processor for even cuts. No one's judging!
Step 2: Sauté Aromatics (2–3 Minutes)
- Heat a large non-stick skillet or wok over medium heat.
- Add 2 tablespoons sesame oil.
- Toss in the minced garlic, onion, and green onion whites (if separated).
- Stir-fry for 2–3 minutes until the onion becomes translucent and the garlic is fragrant. Don’t let it burn!
No sesame oil? Swap in neutral oil like canola or avocado oil — the flavor profile changes slightly, but it’s still delicious.
Step 3: Cook Zucchini & Add Seasonings (5–7 Minutes)
- Add the julienned zucchini to the pan. Stir well to coat with oil and aromatics.
- Cook for 1–2 minutes, then add the gochujang and coarse gochugaru.
- Stir constantly for another 2–3 minutes until the zucchini softens but still holds its shape — you want it tender, not mushy.
- Turn off the heat. Drizzle in the remaining 1 tsp sesame oil and sprinkle in toasted sesame seeds.
- Toss gently one last time. Cover for 1 minute to let flavors meld.
Taste test tip: Adjust saltiness with a pinch of soy sauce if needed — gochujang varies in salt content.
Pro Tips (for the best texture and flavor)
- Don’t overcook zucchini. When it goes from “tender-crisp” to “sad and soggy,” it also releases more water.
- Use a wide pan (or cook in two batches) so the zucchini stir-fries instead of steaming.
- Add sesame oil off-heat for the best aroma.
Easy Variations
1) Make it a rice bowl (덮밥 vibes)
Serve over hot rice and top with:
- fried egg (runny yolk = instant sauce)
- extra sesame seeds
- optional: kimchi on the side
2) Make it a noodle topper
Pile it onto:
- bibim somyeon (thin wheat noodles) with a spicy-sweet sauce
- warm noodle soup as a quick garnish (great when you’re out of energy but still want “real food”)
3) Add protein
Stir-fry at the beginning with the onion:mthin-sliced beef, chicken, shrimp, eggs, or crumbled tofu
Substitutions (especially for Yondu & perilla oil)
Yondu substitute (good, not identical)
Yondu is savory and umami-rich (fermented soybean essence + vegetable extracts).
If you don’t have it, try one of these:
- Option A (best overall): 2 tsp soy sauce + 2 tsp water
- Option B: Light vegetable stock (very small amount)
- Option C: Soy sauce + a pinch of mushroom powder or MSG (optional)
Because Yondu can be salty, add substitutes gradually and taste.
Perilla oil substitute
- Use neutral oil to cook.
- Keep the sesame oil finish (still gives a great Korean aroma).
Perilla oil has a distinct nutty-grassy flavor; it’s unique, but the dish still works without it.
