What Ingredients are in BBQ Sweet-and-Sour Indonesian Tofu?

My favourite thing about this BBQ Sweet-and-Sour Indonesian Tofu is how it combines everyday pantry staples with fresh vegetables to create something truly spectacular. The beauty of this dish lies in its perfect balance of flavours, tangy, sweet, spicy and savoury all dancing together in harmony. What makes it special is the sauce, which creates that distinctive sweet-and-sour profile that’s utterly irresistible.

• 1 pound firm tofu
• 2 tablespoons olive oil
• 3 garlic cloves, crushed
• 1 medium onion, thinly sliced
• 2 medium carrots, cut into matchsticks
• 1 green bell pepper, sliced into strips
• 1 stalk celery, chopped into strips
• 1/2 cup sliced fresh mushrooms
• 1 tablespoon cornflour
• 3/4 cup vegetable stock (or water)
• 3 tablespoons rice vinegar
• 3 tablespoons sugar
• 1 tablespoon ketchup
• 2 tablespoons soy sauce
• 1/2 teaspoon ground ginger
• 1/4 teaspoon cayenne pepper

When shopping for this recipe, do pay attention to the tofu quality. Extra-firm or firm tofu works best as it holds its shape nicely during cooking. For a more authentic taste, you might consider using palm sugar instead of regular sugar, though it’s not essential. The vegetables can be swapped based on what’s in season or what you have in your fridge—red peppers, baby corn, or water chestnuts would make brilliant additions. Feel free to adjust the cayenne pepper amount depending on how spicy you prefer your meals.

How to Make this BBQ Sweet-and-Sour Indonesian Tofu

Preparing this BBQ Sweet-and-Sour Indonesian Tofu on your outdoor cooker transforms an already delicious dish into something with wonderful smoky depth. Start by pressing 1 pound of firm tofu, simply wrap it in paper towels and place a heavy saucepan on top while you prepare the rest of your ingredients. This vital step removes excess moisture, allowing your tofu to achieve that perfect texture on the barbecue.

For the cooking method, I find indirect grilling works beautifully on any type of barbecue. First, prepare your sauce by mixing 1 tablespoon cornflour with 3 tablespoons of vegetable stock in a small bowl until smooth. Then add the remaining stock (to make 3/4 cup in total), 3 tablespoons rice vinegar, 3 tablespoons sugar, 1 tablespoon ketchup, 2 tablespoons soy sauce, 1/2 teaspoon ground ginger and 1/4 teaspoon cayenne pepper.

Set your barbecue to a medium heat of about 180°C with a heavy cast iron pan or plancha on the grill. Add 2 tablespoons olive oil and stir-fry 3 crushed garlic cloves with 1 medium thinly sliced onion and 2 medium carrots (cut into matchsticks) until slightly softened. The smoky environment of the barbecue adds a lovely dimension that you simply can’t achieve in a kitchen.

Now for the fun part, add your 1 green bell pepper (sliced into strips), 1 stalk of celery (chopped into strips) and 1/2 cup sliced fresh mushrooms to the pan, continuing to stir-fry for another few minutes. Cut your pressed tofu into cubes or strips and place them directly on the barbecue grates for about 2-3 minutes per side to achieve those gorgeous grill marks.

Once the vegetables have softened, give your sauce mixture a good stir and pour it into the pan, cooking until it thickens. Finally, add your beautifully grilled tofu to the vegetables, allowing everything to heat through. The combination of the sweet-sour sauce with that subtle smokiness from the barbecue creates an absolutely stunning dish that’s ready to be served straight from the barbecue over a bed of fluffy rice.

Might I suggest keeping the lid closed between stirring to trap that wonderful smoky flavour? Using a cast iron surface will help achieve excellent heat conduction for grilling.

What to Serve with BBQ Sweet-and-Sour Indonesian Tofu

While this BBQ Sweet-and-Sour Indonesian Tofu dish shines as a main attraction, pairing it with complementary sides can turn your meal into a complete feast.

I always serve it over steamed jasmine rice, which soaks up that delicious sauce perfectly!

For flavour pairings that really work, I love adding a simple cucumber salad with rice vinegar dressing. The cool crispness balances the sweet-sour punch of the tofu.

If you want more substantial side dishes, try some garlic green beans or stir-fried bok choy.

Don’t forget a basket of warm roti or naan bread for scooping up extra sauce!

For a revitalising drink, nothing beats a cold glass of limeade or iced green tea to complete your Indonesian-inspired meal.
