Ingredients

Instructions

Step 1: Preparing the Tempe

Begin by heating a large skillet or wok over medium heat. Add a tablespoon of cooking oil—preferably peanut or vegetable oil, which has a high smoke point and neutral flavor. Once the oil is shimmering, carefully add the sliced tempe. Spread the pieces evenly across the pan to ensure uniform cooking. Fry the tempe for approximately 3-4 minutes on each side, flipping occasionally to promote even browning. The goal is to achieve a crispy exterior with a golden hue, while the interior remains tender yet firm. This process enhances the nutty aroma of the tempe and provides a satisfyingly crunchy texture that complements the tender vegetables later in the dish. Once golden, transfer the tempe to a plate lined with paper towels to drain excess oil. Set aside for later incorporation into the stir-fry.

Step 2: Preparing Aromatics and Vegetables

While the tempe is frying, prepare your aromatics. Mince the garlic and shallots finely—this ensures they release maximum flavor during sautéing. Slice the red bell pepper diagonally into thin strips, revealing their vibrant red color, which adds visual appeal and sweetness. If using small chili, slice it thinly, adjusting the quantity based on your desired heat level. Remember, the chili’s spiciness can vary, so start with a small amount and increase if necessary. Set all aromatics aside for the next step.

Step 3: Sautéing the Aromatics

In the same pan used for frying the tempe, add a little more oil if needed, maintaining a medium heat. Once hot, add the minced shallots and garlic. Sauté for about 1-2 minutes until fragrant and slightly translucent, being careful not to burn the garlic. Next, add the sliced red bell pepper and chili, stirring frequently. Cook for an additional 1-2 minutes until the peppers are fragrant and beginning to soften. This step develops the foundational aroma and flavors that will permeate the entire dish, creating a rich, savory profile typical of Indonesian stir-fries. The quick sautéing preserves the bright colors and crunch of the vegetables while imparting deep flavors.

Step 4: Cooking the Long Beans

Add the sliced long beans to the pan, stirring well to coat them with the aromatic mixture. To aid in softening the beans without overcooking, add a splash of water—about 2 tablespoons. Cover the pan briefly or allow the water to evaporate while stirring occasionally. Cook for 3-5 minutes until the beans are tender yet still retain a slight crunch, characteristic of fresh stir-fry vegetables. The steam generated by water helps to soften the long beans evenly and enhances their flavor. Be vigilant to prevent overcooking, as the beans should be vibrant green, crisp, and slightly tender.

Step 5: Seasonings and Flavoring

When the long beans are nearly done, introduce the seasonings. Add the pinch of palm sugar or brown sugar, stirring until dissolved, balancing the savory and sweet elements. Pour in the oyster sauce and soy sauce, stirring thoroughly to coat the vegetables evenly. The oyster sauce adds umami depth, while the soy sauce contributes saltiness and richness. Stir and cook for another 1-2 minutes, allowing the flavors to meld and the sauce to slightly thicken. Taste the mixture to gauge if additional seasoning is needed, adjusting with more soy sauce or sugar as desired. The balance between sweet, salty, and umami creates a layered flavor profile that is characteristic of Indonesian stir-fries.

Step 6: Incorporating the Fried Tempe

Finally, reintroduce the fried tempe into the pan. Gently fold the tempe pieces into the vegetable mixture, ensuring they are well coated with the sauce and aromatics. Drizzle the sweet soy sauce (kecap manis) over the entire dish, giving it that signature glossy appearance and rich sweetness. Stir gently to combine, taking care not to break the tempe pieces. Continue cooking for another 1-2 minutes, allowing the flavors to infuse into the tempe and vegetables. This step ensures the dish is thoroughly combined, with each ingredient contributing to the overall harmony of flavors and textures.

Step 7: Final Tasting and Adjustments

Remove the stir-fry from heat and taste a small portion to evaluate seasoning. Adjust with additional soy sauce, kecap manis, or sugar if necessary to suit your palate. The dish should be savory, slightly sweet, and aromatic, with a hint of spice if chili was added. The tempe should be crispy on the outside and tender within, while the long beans retain their crunch. Serve hot for the best sensory experience.

Preparation Tips

• Use fresh, firm tempe to ensure a good texture after frying. Older tempe can become overly soft and lose its crunch.
• Slice vegetables uniformly for even cooking, which also improves presentation.
• Adjust spice levels early by adding more or less chili, depending on your preference.
• For a more authentic flavor, consider adding a splash of Indonesian fish sauce or a pinch of turmeric powder during sautéing.
• Ensure your pan is hot enough before adding ingredients to prevent sticking and to achieve a good sear.

Nutritional Information

Tips and Tricks

• Soak sliced tempe in a little water with a splash of vinegar for 10 minutes before frying to reduce oil absorption and enhance crispness.
• Use high heat to stir-fry quickly, preserving the crunch of the vegetables and preventing sogginess.
• Prepare all ingredients beforehand for a smooth cooking process — stir-frying is fast-paced.
• For added flavor, sprinkle chopped scallions or fried shallots on top before serving.

Add-ons

• Tofu or chicken strips for extra protein
• Fresh lime juice for a hint of acidity
• Crushed peanuts or fried shallots as garnish
• Additional fresh herbs like cilantro or Thai basil

Side Dishes

• Steamed jasmine rice
• Indonesian fried rice (Nasi Goreng)
• Steamed vegetables or sambal for heat
• Grilled skewers or satay for added protein

Improvements

• Experiment with different vegetables such as carrots, bok choy, or spinach for variety.
• Use homemade kecap manis for a fresher, more nuanced sweetness.
• Incorporate a dash of sesame oil at the end for additional aroma and flavor complexity.
• Adjust cooking times to enhance texture—less for crunchier, more for softer vegetables.

Save and Store

This stir-fry is best enjoyed immediately for optimal texture and flavor. However, leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, use a skillet over medium heat, stirring occasionally until heated through. Avoid microwaving for prolonged periods, as this can make the tempe soggy and diminish the crispness of the tempe.

FAQ

Can I make this dish vegan?

Yes, simply replace oyster sauce with a vegan stir-fry sauce or mushroom-based sauce, and ensure kecap manis is free from animal derivatives. All other ingredients are plant-based.

What if I can’t find long beans?

Green beans or snap peas are suitable substitutes, though they will alter the flavor slightly. Adjust cooking time accordingly to maintain a desirable crunch.

Is tempe healthy?

Tempe is rich in protein, fiber, vitamins, and probiotics, making it a nutritious addition to your diet. It is lower in fat than fried meats and provides plant-based protein suitable for vegetarians and vegans.
