Instructions

1. Prepare Tempe and Tofu

Begin by gently rinsing the blocks of tempe and tofu under cold running water to remove any surface impurities or residual packaging residues. Pat them dry with a clean kitchen towel or paper towels. Using a sharp chef’s knife, carefully cut both the tempe and tofu into small, uniform cubes—about 1 to 1.5 centimeters in size. Uniformity ensures even frying and consistent texture throughout the dish.

For frying, choose a neutral oil with a high smoke point such as peanut, vegetable, or canola oil. Pour enough oil into a deep skillet or wok to submerge the cubes during frying, approximately 1-2 inches deep. Heat the oil over medium-high heat until it reaches about 180°C (356°F); a good test is to drop a small piece of tofu or tempe into the oil—if it sizzles immediately and rises to the surface, it’s ready.

Using a slotted spoon or spider strainer, carefully fry the tempe and tofu in batches to avoid overcrowding, which can cause temperature drops and uneven frying. Fry until the exterior is golden brown and crispy, which typically takes about 3-4 minutes per batch. The interior should remain tender. Once fried, transfer the cubes to a plate lined with paper towels to drain excess oil. Set aside.

2. Prepare Vegetables and Aromatics

While frying, prepare the long beans by rinsing them thoroughly under cool water. Trim the ends and cut the beans into 3-5 centimeter (1-2 inch) segments. This length is ideal for stir-frying as it allows for easy handling and a good bite-sized portion.

For aromatics, peel the garlic cloves and mince them finely using a garlic press or a sharp knife. Slice the shallots thinly to maximize flavor release during sautéing. If you prefer milder heat, adjust the chili peppers accordingly. Slice them thinly, and set aside. For the galangal, if fresh, peel with a vegetable peeler or knife, then crush or grate finely. If using dried, rehydrate briefly in warm water before crushing.

Gather bay leaves and set aside. These aromatic leaves add subtle depth and fragrance to the dish but are removed before serving.

3. Sauté Aromatics and Spices

In the same wok or large frying pan used for frying, add a tablespoon of oil—preferably peanut or vegetable oil for authentic flavor. Heat over medium heat until shimmering. Add the minced garlic and sliced shallots, stirring constantly to prevent burning. Cook until they become fragrant and turn a light golden color, approximately 1-2 minutes.

Add the sliced chili peppers and crushed galangal. Continue sautéing for another minute, allowing the spices and aromatics to release their essential oils, creating a fragrant base that will infuse the entire dish.

4. Stir-Fry the Long Beans

Next, introduce the prepared long beans into the pan. Stir-fry for about 2-3 minutes, ensuring the beans are coated with the aromatic mixture. To help them cook evenly and retain their vibrant green color, add a splash of water—about a tablespoon—and cover the pan with a lid. This creates steam, softening the beans slightly while preserving their crunch.

Allow the beans to cook for an additional 2-3 minutes, checking periodically. They should be tender but still crisp, with a bright green hue. If they become too soft, remove the lid and stir-fry briefly to reintroduce some crunch.

5. Incorporate Fried Tempe and Tofu

Gently add the fried tempe and tofu cubes to the wok, being careful not to break them apart. Stir softly to combine them with the vegetables and aromatics, ensuring an even distribution without damaging the crispy exterior.

This step is crucial for maintaining the texture contrast that makes this dish so appealing. Use a spatula or wooden spoon to toss lightly, avoiding vigorous stirring that could dislodge the crispy coating.

6. Season the Dish

Now, it’s time to season. Add sugar, salt, and Royco seasoning cube, if using, according to your taste preferences. Incorporate ground black pepper for subtle spiciness. Drizzle in sweet soy sauce (kecap manis) and oyster sauce, starting with small amounts and adjusting as needed. These sauces provide the signature sweet, savory, and umami notes characteristic of Indonesian cuisine.

Stir everything gently to coat the ingredients thoroughly. The sauces should be evenly distributed, creating a glossy, flavorful layer that enhances the dish’s depth.

7. Simmer and Final Touches

Continue stir-frying over medium heat until the sauce has slightly reduced, and the ingredients are heated through. Be careful not to overcook—long beans should remain vibrant and slightly crunchy. The tempe and tofu should be heated thoroughly, with the exterior crisp and the interior tender.

Remove bay leaves before serving, as these are aromatic but not meant to be eaten directly. Taste and adjust seasoning—add more soy sauce or sugar if necessary to balance flavors.

8. Serve

Transfer the stir-fry to a serving dish. Serve hot, ideally with a side of steamed jasmine rice or coconut rice for an authentic Indonesian experience. Garnish with additional sliced chili or fried shallots for extra flavor if desired.

Preparation Tips

• Frying tempe and tofu: Ensure the oil is hot enough to avoid soggy texture. Fried cubes should be crispy on the outside and tender inside, so do not overcrowd the pan.
• Handling galangal: Fresh galangal imparts a citrusy, pine-like flavor; crush or grate finely for maximum flavor release.
• Adjusting spiciness: Add chili peppers gradually, tasting as you go, to achieve your preferred heat level.
• Vegetable prep: Uniform cutting ensures even cooking and consistent texture.
• Sauce balancing: Start with small amounts of sauces, then taste and adjust to prevent overpowering sweetness or saltiness.

Tips and Tricks

• Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat in a wok or microwave, adding a splash of water or oil to revive crispness.
• Customizing flavor: For extra depth, add a touch of fish sauce or a squeeze of lime at the end.
• Spice level: Feel free to incorporate additional chili paste or fresh sliced chilies for heat, or omit entirely for milder flavor.
• Vegetable variations: Incorporate other vegetables like bell peppers or carrots for color and nutritional variety.

Add-ons and Variations

• Protein enhancements: Add sliced chicken, shrimp, or beef for a non-vegetarian version.
• Vegan adaptation: Replace oyster sauce with mushroom-based soy sauce or omit entirely.
• Extra aromatics: Sprinkle with fried shallots or chopped scallions before serving for added flavor and presentation.

Side Dishes

• Steamed jasmine rice
• Coconut rice for a richer flavor
• Indonesian sambal or chili sauce for extra heat
• Pickled vegetables or acar for a tangy contrast
• Fried shallots or crispy garlic as garnish

Improvements

• Use homemade or high-quality soy and oyster sauces for richer flavor
• Experiment with different types of beans or vegetables for variety
• Incorporate a splash of coconut milk during stir-frying for a creamy twist
• Try adding toasted ground peanuts or sesame seeds for added texture and flavor

Save and Store

Allow the dish to cool completely before transferring to an airtight container. Store in the refrigerator for up to 2 days. To reheat, stir-fry in a hot pan or microwave until heated through. For best results, add a splash of water or oil during reheating to maintain texture and flavor. Avoid freezing, as fried ingredients may lose their crispness upon thawing.

FAQ

Can I make this dish vegan?

Absolutely. Simply replace oyster sauce with a mushroom-based soy sauce or omit it altogether. Ensure that your soy sauce and other seasonings are gluten-free if necessary.

What if I can’t find galangal?

Fresh ginger can be used as a substitute, though it imparts a slightly different flavor. Use half the amount and adjust to taste. Dried galangal can be rehydrated in warm water before use.

Can I prepare this dish ahead of time?

Yes, but for optimal texture, fry the tempe and tofu just before serving. Vegetables can be prepped in advance and stir-fried quickly when ready to serve. Reheat leftovers gently to preserve textures.

How spicy is this dish?

The spiciness depends on the chili peppers used. Adjust the amount according to your heat preference. For milder flavor, omit or reduce the chili peppers.

Is this gluten-free?

Potentially, yes. Use gluten-free soy sauce and oyster sauce if available. Always check labels to ensure ingredients meet gluten-free standards.
