Ingredients

Instructions

1. Prepare the Kangkung

Begin by carefully selecting fresh kangkung. Remove any yellow or wilted leaves and rinse thoroughly under cold running water to eliminate dirt, grit, or any residual pesticides. The water spinach should be crisp and vibrant green, indicating freshness. After washing, drain the kangkung using a strainer or colander, and set aside to dry slightly. If the leaves are large, you may chop the stalks into manageable pieces for easier stir-frying, but typically, the whole bunch can be used as-is for a more rustic presentation.

2. Slice the Tempe

Take the small block of tempe and cut it into your preferred shapes—squares, rectangles, or even strips. The choice depends on personal preference and presentation style. Thinner slices or smaller cubes will cook faster and absorb flavors more readily. For this dish, aim for pieces approximately 1.5 centimeters thick. Use a sharp knife to ensure clean cuts, which helps maintain the integrity of the tempe during frying. The tempe should be fresh, firm, and uniformly sliced to ensure even browning.

3. Sauté Aromatics

Heat a wok or large frying pan over medium heat. Add a generous splash of cooking oil—about 2 to 3 tablespoons—to ensure even coating and prevent sticking. Once the oil is hot but not smoking, add the sliced shallots and garlic. Sauté them gently, stirring frequently, until fragrant and slightly translucent. This process releases their essential oils, creating a fragrant base for the entire dish. Be attentive to avoid burning the shallots or garlic, which can impart a bitter taste. Stir continuously to achieve a golden hue and a pleasant aroma.

4. Incorporate Chilies

Add the sliced curly chili peppers and bird’s eye chilies to the pan. Stir well, allowing the chilies to soften slightly and release their spicy oils. The amount of chili can be adjusted based on personal heat tolerance—use fewer if you prefer milder flavors or more for an authentic fiery kick. Continue stir-frying until the chilies are fragrant, which usually takes about 30 seconds to a minute. This step is crucial as it infuses the oil with spicy notes that will carry through the entire dish.

5. Cook the Tempe

Add the sliced tempe to the pan. Spread the pieces out evenly and cook without stirring for about 2-3 minutes to allow them to develop a golden crust. Then, stir or flip the tempe to cook all sides evenly, continuing until each piece turns a rich, golden brown. The frying process enhances the nutty flavor of tempe and gives it a slightly crispy exterior while remaining tender inside. Be cautious not to overcrowd the pan to ensure proper browning. If necessary, cook in batches.

6. Incorporate Kangkung

Once the tempe is browned, quickly add the prepared kangkung to the pan. The leaves and stalks will wilt rapidly when exposed to heat, so add them in batches if needed. Immediately pour in the oyster sauce—start with about 1 tablespoon—and season with salt. For added sweetness, sprinkle sugar if desired. Incorporate any optional flavor enhancers, such as MSG or chicken powder, for an extra umami boost. Use tongs or a spatula to toss everything together, ensuring the kangkung is coated evenly with the seasonings.

7. Cook Until the Kangkung Wilts

Stir-fry the mixture for about 1-2 minutes, just until the kangkung leaves are wilted but still retain a slight crunch. The key is to preserve the freshness and texture of the greens, which contrasts beautifully with the savory and spicy elements. Avoid overcooking, as this can lead to a soggy dish and loss of vibrant color and nutrients.

8. Final Adjustments and Serving

Taste the dish and adjust seasonings as necessary—add more salt, oyster sauce, or chili if desired. Once satisfied, turn off the heat. Transfer the Tumis Kangkung Tempe to a serving dish immediately to retain its vibrant appearance and crunchiness. Serve hot, ideally alongside steamed rice or as part of a larger Indonesian meal.

Preparation Tips

• Use fresh ingredients: The flavor of the dish heavily relies on the freshness of kangkung, chilies, and tempe. Fresh produce yields the best aroma and texture.
• Adjust spiciness: Bird’s eye chilies are intensely spicy. Adjust the quantity based on your heat preference or substitute with milder chilies if desired.
• Control heat level: Keep the heat at medium to prevent burning aromatics and to allow even cooking of ingredients.
• Pre-wash and dry kangkung thoroughly: Excess water can cause splattering during stir-frying. Drying ensures safety and better cooking results.
• Use the right oil: Neutral oils like vegetable or peanut oil are preferred to keep the flavors clean and allow the spices to shine.

Nutritional Information

Tips and Tricks

• Marinate tempe: For deeper flavor, marinate tempe slices in soy sauce and a splash of rice vinegar for 10-15 minutes before frying.
• Enhance aroma: Add a dash of toasted sesame oil at the end for a nutty aroma.
• Keep kangkung crunchy: Do not overcook; remove from heat as soon as the greens wilt.
• Use high heat: Stir-fry over high heat for quick cooking and retain vibrant colors and textures.

Add-ons

• Chopped peanuts for added crunch
• Fried shallots or garlic as topping
• Fresh lime wedges for a tangy contrast
• Additional protein: fried egg, tofu, or shrimp

Side Dishes

• Steamed jasmine rice – the classic pairing that balances the spiciness and savoriness
• Indonesian sambal – for those who love extra heat and flavor
• Fried tempeh or tahu (tofu) – for additional protein and texture
• Pickled vegetables – to add acidity and freshness

Improvements

• Use homemade oyster sauce or a vegetarian alternative for a cleaner, more natural flavor.
• Incorporate a splash of coconut milk during stir-fry for creaminess and richness.
• Experiment with adding sliced mushrooms or bell peppers for additional flavor and nutrition.
• Try different chili combinations, such as Thai bird chilies or Fresno peppers, for varying heat levels and flavor profiles.

Save and Store

Leftover Tumis Kangkung Tempe can be stored in an airtight container in the refrigerator for up to 24 hours. However, the kangkung may lose some of its crunchiness and become slightly wilted. To reheat, do so quickly over high heat in a wok or skillet to preserve as much texture as possible. For best results, consume fresh for optimal flavor and texture.

FAQ

Can I make this dish vegan?

Yes. Simply replace oyster sauce with a vegan-friendly soy or mushroom-based sauce. Ensure that all seasonings and flavorings used are plant-based.

Can I use frozen water spinach?

Fresh kangkung is preferred for its texture and flavor, but frozen can be used in a pinch. Thaw thoroughly and drain excess moisture before cooking to prevent sogginess.

How spicy is this dish?

The level of spiciness depends on the chili types and quantities used. Bird’s eye chilies are very hot; adjust accordingly. Always taste and modify the amount of chilies to suit your spice tolerance.

Is this dish suitable for vegetarians?

It is vegetarian if you omit the oyster sauce or replace it with vegetarian alternatives. It is also naturally dairy-free and vegan-friendly with suitable substitutions.
