Instructions

Step 1: Preparing the Ingredients

Begin by gathering all your ingredients and preparing them for cooking. Slice the shallots into thin, uniform strips to maximize their surface area and enhance caramelization. Mince the garlic finely to release maximum flavor. Chop the green chilies into small rings, taking care to wear gloves if you are sensitive to spicy oils or to avoid skin irritation. For the bird’s eye chilies, adjust the quantity based on your heat preference—these are especially spicy and should be used judiciously.

Dice the tomato into small cubes, ensuring they are evenly sized to cook uniformly and release their juices during sautéing. Prepare the tempeh by slicing it into strips or cubes, depending on your preference, then set aside.

Step 2: Frying the Tempeh

In a large frying pan or wok, heat enough cooking oil to fully submerge or adequately fry the tempeh. When the oil reaches approximately 170°C (340°F), add the tempeh slices or cubes carefully. Fry them until they develop a light golden color and a slight crispy texture on the edges—this process should take about 3-4 minutes per batch. Use a slotted spoon or strainer to remove the fried tempeh from the oil and drain excess oil on paper towels.

Fried tempeh not only adds texture but also absorbs flavors better during the stir-frying process, making each bite flavorful and satisfying.

Step 3: Sautéing Aromatics

In a clean wok or pan, heat approximately 2 tablespoons of cooking oil over medium heat. When the oil is hot enough (test by flicking a small bit of shallot or garlic into the oil—if it sizzles immediately, the oil is ready), add the sliced shallots and minced garlic. Sauté, stirring constantly, until they turn golden brown and aromatic, about 2-3 minutes. This step forms the fragrant base of your dish.

Be attentive to prevent burning, as burnt garlic and shallots can impart a bitter taste. Adjust the heat if necessary to maintain a gentle sizzle.

Step 4: Incorporating Chilies and Tomato

Add the chopped green chilies and bird’s eye chilies into the pan. Stir well to coat the aromatics in the spicy oils. Continue sautéing for an additional 2 minutes to release the heat and aroma from the chilies. Next, add the diced tomato, stirring to combine. Cook for 3-4 minutes until the tomato softens and releases its juices, creating a flavorful base sauce.

This step intensifies the chili aroma and begins to build the spicy, tangy profile characteristic of the dish.

Step 5: Creating the Sauce

Pour a small splash of water into the pan—about 2 tablespoons—to loosen the mixture and help in developing a sauce-like consistency. Stir to incorporate the water, which will help meld the flavors together. Add salt, palm sugar, and sweet soy sauce (kecap manis) according to your taste preferences. Use a small spoon or measuring spoons to adjust these seasonings carefully.

Let this mixture simmer gently for 2-3 minutes, allowing the flavors to meld and the sauce to slightly reduce.

Step 6: Combining Tempeh and Final Cooking

Add the previously fried tempeh into the pan, stirring gently to coat each piece with the spicy-sweet sauce. Reduce the heat to low-medium and continue cooking for another 5-7 minutes, stirring occasionally. This allows the tempeh to absorb the flavors fully and the sauce to thicken slightly.

Be cautious not to overcook, as tempeh can become too soft if cooked excessively. The goal is to have a flavorful, slightly sticky coating on the tempeh with a balanced spicy-sweet profile.

Step 7: Tasting and Adjusting Seasonings

Taste the dish and adjust seasonings as needed. If you prefer it sweeter, add a touch more palm sugar. For more heat, incorporate additional chopped chilies or a dash of chili flakes. If the sauce is too thick, add a splash of water to loosen it. For more saltiness, sprinkle a little more salt or soy sauce.

Step 8: Serving

Once the tempeh is well coated and the flavors are harmonized, remove the pan from heat. Serve the spicy sweet tempe stir-fry hot, garnished with fresh herbs such as chopped cilantro or sliced scallions if desired. Accompany with steamed jasmine rice or any preferred grain to complete the meal.

The dish is best enjoyed fresh but can be stored for later use with some quality reheating.

Preparation Tips

• Use firm or extra-firm tempeh for better texture; softer varieties may fall apart during frying.
• Frying tempeh until golden and slightly crispy enhances flavor and texture, providing a better base for absorbing the sauce.
• Adjust the heat level by varying the number of bird’s eye chilies; always taste as you go to prevent overpowering spiciness.
• For a richer flavor, consider adding a splash of coconut milk during the final simmering stage.
• Marinate the tempeh briefly in soy sauce or spices before frying for enhanced flavor.

Nutritional Information

Tips and Tricks

• Control spice levels: Always taste the chilies before adding more. If you want milder heat, remove seeds from chilies or use fewer bird’s eye chilies.
• Enhance umami: Incorporate a dash of fish sauce (for non-vegetarians) or mushroom soy sauce for an extra savory depth.
• Make ahead: Prepare the fried tempeh and sauce mixture in advance. Reheat gently before serving to maintain texture.
• Vegetable variations: Add bell peppers, carrots, or snap peas for additional crunch and nutrients.

Add-ons

• Fresh herbs like cilantro, basil, or scallions for garnish
• Fried shallots or crispy garlic for added crunch
• Chopped peanuts or cashews for texture contrast
• Lime wedges for a citrusy brightness

Side Dishes

• Steamed jasmine or basmati rice
• Indonesian-style sambal or chili paste
• Fresh vegetable salad with lime dressing
• Pickled vegetables or acar
• Fried plantains or crispy crackers for extra flavor

Improvements

• Use coconut aminos as a soy-free alternative for a different flavor profile
• For a smoky flavor, add smoked paprika or grill the tempeh before stir-frying
• Incorporate grated ginger with aromatics for additional depth
• Experiment with different types of chilies to vary heat and flavor

Save and Store

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in a skillet over low heat or in the microwave, adding a splash of water or oil to revive the sauce. For longer storage, freeze in portions for up to 1 month; thaw thoroughly before reheating.

To preserve the texture of fried tempeh, consider storing it separately and adding it to the sauce just before serving.

FAQ

Can I make this dish vegan?

Absolutely. Simply omit or substitute the sweet soy sauce with a vegan alternative like coconut aminos or tamarind paste. Ensure any additional seasonings are plant-based.

Can I adjust the spiciness?

Yes. Control the heat by adjusting the number and type of chilies used. Bird’s eye chilies are very spicy, so start with fewer and add more if desired. Removing seeds can also reduce heat.

What can I serve with this dish?

It pairs beautifully with steamed rice, but you can also serve it with noodles, quinoa, or even as a filling for wraps or sandwiches.

Is tempeh healthier than tofu?

Tempeh is fermented, which can aid digestion and increase probiotic content. It also tends to have higher protein and fiber levels compared to tofu, making it a nutritious choice.
