Grilled vegetables on the BBQ (Asian marinade)

🥢 1h marinade in the fridge — non-negotiable (30 min express OK)

The secret of this recipe: 1 hour of marinating in the fridge before cooking. That’s what lets the soy sauce penetrate deeply into the peppers and mushrooms (which absorb best). Express minimum 30 minutes, no less. Max 1h-1h30 — not 2 hours, the soy sauce would start over-salting the softer vegetables like zucchini.

🥣 Keep half the marinade to baste + finish

When preparing the marinade, I put half on the vegetables to marinate and keep the other half in the fridge in a small jar. During cooking in the BBQ wok, baste with fresh marinade. Out of the BBQ, pour the vegetables into a large serving bowl and add the rest of fresh marinade, mix — it wakes up the flavors and adds a fresh layer over the caramelization. Detail that transforms the dish.

🍳 BBQ wok — the signature technique

I use a real BBQ wok (not direct grill, not skewers). Why? It holds the liquid marinade, lets you stir constantly for even caramelization, and prevents small pieces from falling into the flames. Without a BBQ wok, valid alternative: perforated BBQ basket or perforated aluminum foil on the grill. Avoid skewers for this recipe — zucchini rounds slip off.

🥦 Vegetable variants — seasonal and Asian

The 6 base vegetables (3 peppers + zucchini + red onion + white mushrooms) are perfect. Seasonal variants: asparagus in spring, corn kernels in summer, cauliflower in fall. Next-level Asian variants: broccoli, bok choy, gai lan (Chinese broccoli). Use what you have in the fridge — the marinade goes with everything.

🍄 Mushrooms — pro variants

White mushrooms do the job. For more flavor: cremini (one notch up), portobello in large chunks (meaty texture), shiitake (intense umami, authentic Asian profile). Shiitake with this marinade = divine combo.

🍆 Eggplant — yes but mind the water

You can absolutely add eggplant cut into large cubes (1-2 cm). Watch out: eggplant releases a lot of water during cooking. Trick to avoid: sprinkle the cubes with salt before marinating, let sit 15 minutes to draw out water, then pat dry with paper towels before adding to the marinade. Otherwise, your marinade gets diluted.

🍯 Maple sweet-savory variant — Quebec twist

For a more Quebec sweet-savory version, add 1 tbsp (15 ml) maple syrup to the marinade. The sugar caramelizes on the BBQ and creates a beautiful golden glaze on the vegetables. Compatible with the Asian profile (maple plays well with soy and sesame). Worth trying at least once.

🧄 Fresh ginger + garlic variant — pro version

To push the Asian profile even further, add to the marinade: 1 tsp (5 ml) fresh Microplane-grated ginger + 2 finely minced garlic cloves. Gives a fresh, piquant dimension that pairs perfectly with the soy sauce. Optional but recommended for next-level version.

🥗 Express complete meal — rice, soba, quinoa, tofu

To turn these vegetables into an express main meal, throw them on a bed of basmati rice, soba noodles, quinoa, or rice vermicelli. Add smoked tofu in cubes for protein. In 2 minutes, you’ve got a complete vegetarian Asian bowl with nothing else to prep.

♻️ Reheating leftovers — pan over high heat

Next day, reheat in a pan over high heat for 3-4 minutes, stirring. Caramelization comes back, vegetables stay crunchy. Microwave works but vegetables go soft. Bonus: the marinade made ahead keeps 4-5 days in the fridge in an airtight Mason jar, and the grilled vegetable leftovers keep 2-3 days.

✅ What to serve with my Asian-marinade BBQ grilled vegetables?

Universal side: grilled meat (steak, skewers, ribs), fish like my maple teriyaki salmon or my tuna tataki with sesame crust, or complete Asian meal with my chicken Pad See Ew, my chicken chow mein or my Singapore noodles. Perfect Asian BBQ side for summer evenings.
