Instructions

Step 1: Preparing the Ingredients

Begin by meticulously washing all fresh produce. Rinse the long beans under cold running water to remove any dirt, debris, or surface impurities. Pat them dry with a clean towel or paper towels, then trim the ends and cut into 2-3 inch segments. This length strikes a balance between ease of stir-frying and bite-sized presentation, making it ideal for eating with chopsticks or forks.

Next, prepare the proteins. Dice the tofu into uniform 1-inch cubes to ensure even frying and cooking. Use a firm or extra-firm variety; softer tofu may break apart during frying, so pressing out excess moisture beforehand is recommended for optimal crispness. Similarly, cut the tempeh into 1-inch cubes. If desired, you can lightly steam the tempeh beforehand to reduce bitterness, but frying directly imparts a lovely crispy exterior that enhances texture.

Peel and thinly slice the red shallots. These small onions provide a sweet, aromatic base flavor that balances the heat of the chilies. Mince or thinly slice the garlic cloves, which will add depth and fragrance. Crush or finely chop the galangal, a root similar to ginger but with a distinct citrusy and piney aroma that is characteristic of Indonesian dishes. Proper preparation of these aromatics ensures a fragrant and flavorful stir-fry.

Step 2: Frying the Tofu and Tempeh

Heat a generous amount of cooking oil—about 2-3 tablespoons—over medium heat in a large wok or deep frying pan. The oil should be hot enough to sizzle when the tofu and tempeh are added, approximately 350°F (175°C). Use a thermometer for precision or test by dropping a small piece of tofu; if it bubbles immediately, the oil is ready.

Carefully add the diced tofu and tempeh to the hot oil. Fry them in batches if necessary to avoid overcrowding, which can cause steaming rather than frying. Fry until the exterior is golden brown and slightly crispy, about 3-4 minutes per batch. Use a slotted spoon or tongs to turn the pieces occasionally for even browning. Once fried, transfer the tofu and tempeh onto a paper towel-lined plate to drain excess oil. This step ensures the stir-fry isn’t overly greasy and maintains a pleasant texture.

Step 3: Sautéing Aromatics

In the same wok or pan, remove most of the excess oil, leaving just enough to sauté the aromatics. Add the sliced red shallots and garlic, stirring constantly to prevent burning. Sauté over medium heat until they become fragrant and lightly golden, approximately 2-3 minutes. This process releases essential oils, creating a fragrant foundation for the dish.

Step 4: Adding Spices and Aromatic Enhancers

Introduce the crushed bird’s eye chili, sliced red chili, and crushed galangal into the pan. Stir-fry for 1-2 minutes until the spices release their aroma and turn slightly darker. Be cautious with the bird’s eye chili—its heat can be potent—so adjust the quantity according to your spice tolerance. If you prefer milder flavor, add fewer or no bird’s eye chilies. The combination of these spices transports the dish to a traditional Indonesian flavor profile, offering a complex aroma with citrus and spicy notes.

Step 5: Creating the Sauce

Pour in about half a cup of water to create a light sauce base. Stir to incorporate the spices and aromatics, then season with salt, sugar, and sweet soy sauce. The sweet soy sauce, or kecap manis, imparts a characteristic sweetness and depth, balancing the heat and acidity. Taste the mixture and adjust seasonings accordingly—adding more sugar for sweetness, salt for saltiness, or soy sauce for umami. Optional flavor enhancer can be added at this stage for an extra layer of savory richness, but use sparingly and taste as you go.

Step 6: Incorporating Long Beans

Add the prepared long beans into the pan. Stir to evenly distribute. Cook for 3-4 minutes over medium-high heat, allowing the beans to soften slightly while remaining crisp and vibrant in color. Stir frequently to prevent sticking and ensure even cooking. The goal is to preserve the crunchy texture that makes long beans so appealing in stir-fry dishes.

Step 7: Final Assembly and Cooking

Gently fold in the fried tofu and tempeh, ensuring they are coated with the sauce and aromatics. Cook for an additional 3-5 minutes, allowing the flavors to meld. The proteins will soak up the sauce’s flavors, gaining a slight caramelization that enhances their taste. Keep the heat high enough to promote quick cooking but avoid burning the ingredients.

Step 8: Serving

Once the dish reaches the desired flavor intensity and the ingredients are well combined, remove from heat. Serve hot, ideally over steamed jasmine rice or with traditional Indonesian rice cakes. Garnish with additional sliced chilies or fresh herbs like cilantro if desired. This dish is best enjoyed immediately to appreciate the contrasting textures and bold flavors.

Preparation Tips

• Press the tofu for at least 15 minutes prior to cooking to remove excess moisture, which helps achieve a crispier texture.
• Fry the tofu and tempeh separately if you want to control the crispiness and prevent flavor transfer.
• Use fresh long beans for optimal crunch; frozen or older beans may turn mushy.
• Adjust the spice levels by varying the amount of chilies used; for milder versions, omit the bird’s eye chili.
• Experiment with adding other vegetables such as sliced carrots or bell peppers for more color and nutrition.
• Prepare and measure all ingredients beforehand—mise en place—to streamline the stir-fry process.
• Stir-frying over high heat requires constant movement; keep your spatula or wok spoon ready for quick action.
• Ensure the oil is hot enough before frying to prevent sticking and sogginess.

Nutritional Information

Tips and Tricks

• Always fry tofu and tempeh in batches to prevent overcrowding, which diminishes crispiness.
• Use a high smoke point oil such as vegetable or peanut oil for frying.
• For a smokier flavor, add a splash of smoked soy sauce or a dash of liquid smoke during the sauce-making step.
• Ensure the aromatics are sautéed just until fragrant to prevent bitterness or burnt flavors.
• Adjust the sauce’s consistency by adding more water or reducing it to a thicker glaze, depending on preference.
• Use a wok or large skillet suitable for high heat and quick stirring to achieve authentic stir-fry texture.

Add-ons

• Top with chopped scallions or cilantro for freshness.
• Sprinkle toasted sesame seeds for added nuttiness.
• Add a squeeze of lime or calamansi for acidity at serving.
• Include sliced shallots or crispy fried shallots as garnish for extra crunch and flavor.

Side Dishes

• Steamed jasmine rice or fragrant coconut rice
• Indonesian sambal or chili paste for extra heat
• Pickled vegetables such as acar or acar kuning
• Fresh vegetable salad with lime dressing

Improvements

• Add a splash of coconut milk during the sauce step for a richer, creamier texture.
• Include sliced mushrooms or baby corn to diversify textures.
• Use homemade or high-quality soy sauce for enhanced umami flavor.
• Experiment with different types of chili for varied heat profiles, such as Thai bird’s eye or dried red chilies.

Save and Store

This dish is best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a wok or skillet over medium heat, adding a splash of water or soy sauce to revive the flavors. To prevent the tofu from becoming soggy, reheat it separately and combine with the vegetables and sauce just before serving.

FAQ

Can I make this dish vegan?

Absolutely. Use vegan soy sauce and flavor enhancers. Ensure that the kecap manis you select is free from animal-derived ingredients, or substitute with a homemade sweet soy sauce made with molasses, soy sauce, and a sweetener.

Can I use other vegetables?

Yes. Carrots, bell peppers, snap peas, or bok choy make excellent additions or substitutes, providing different textures and flavors. Adjust cooking times accordingly to avoid overcooking delicate vegetables.

How spicy is this dish?

The spice level depends on the amount and type of chilis used. Bird’s eye chili is very hot; use less if you prefer milder flavors. Dried or sliced red chilies add a milder heat.

Is it suitable for gluten-free diets?

Yes. Use gluten-free soy sauce or tamari and verify that all other ingredients are gluten-free.
