Step‑by‑Step Instructions for Vegan Singapore Black Pepper Sauce Spaghetti
Step 1: Prepare the Cauliflower
Begin by cutting the cauliflower into medium-sized florets, ensuring they are uniform for even cooking. Rinse the florets under cold water and pat them dry with a kitchen towel. This will help the batter stick better. Set the prepared cauliflower aside while you whip up the batter for the Vegan Singapore Black Pepper Sauce Spaghetti.
Step 2: Make the Batter
In a mixing bowl, whisk together corn starch and all-purpose flour, creating a light, airy batter. Gradually add cold water, mixing until you achieve a yogurt-like consistency. Aim for a silky texture that will coat the cauliflower but isn’t too thick. This batter is key to achieving that crispy exterior after frying.
Step 3: Heat the Oil
In a deep pan, pour in enough vegetable oil to submerge the cauliflower florets. Heat the oil over medium-high until it reaches about 350°F (175°C). To test the oil, drop a small amount of batter into the pan—if it sizzles and rises, the oil is ready. This is crucial for making sure the cauliflower cooks to a perfect crisp.
Step 4: Fry the Cauliflower
Carefully dip each cauliflower floret in the batter, ensuring they are well-coated, then gently place them in the hot oil. Fry them for about 3-4 minutes or until they float and turn a lovely light golden brown. Remove the fried cauliflower using a slotted spoon and let them drain on paper towels to remove excess oil.
Step 5: Toast the Spices
In a dry pan over medium heat, add the cracked black pepper and ground white pepper. Toast the spices for about 1-2 minutes, stirring frequently, until they become aromatic. This process unlocks their full flavor, enhancing the richness of the Vegan Singapore Black Pepper Sauce Spaghetti. Set the toasted pepper aside for later.
Step 6: Prepare the Sauce
In a mixing bowl, combine the vegan oyster sauce, soy sauce, and sugar, whisking until well blended. This sauce will bring depth and sweetness, perfectly balancing the heat from the black pepper. Set this mixture aside as it will be incorporated into the completed dish later, enriching the flavor of the spaghetti.
Step 7: Cook the Spaghetti
Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package instructions, typically around 8-10 minutes until al dente. Stir occasionally to prevent sticking, and keep an eye on the spaghetti until it reaches that perfect chewy texture. Drain the pasta and set aside, preserving a splash of the cooking water.
Step 8: Sauté Shallots and Garlic
In the same pan used for frying, heat a tablespoon of oil over medium heat. Add shallots and sauté for about 2-3 minutes until they become translucent. Follow by adding minced garlic and sauté for an additional minute, stirring constantly to avoid burning. This fragrant base will enhance the overall flavor of your Vegan Singapore Black Pepper Sauce Spaghetti.
Step 9: Combine the Ingredients
Stir in the fermented bean paste, bird’s eye chili, curry leaves, and the toasted black and white pepper into the shallots and garlic mixture. Cook for another 2 minutes, allowing the spices to meld together. This aromatic mix will form the core of your sauce, creating a delightful foundation for the pasta and cauliflower.
Step 10: Final Toss and Serve
Add the fried cauliflower to the pan along with half of the prepared sauce, gently tossing to coat. Next, add the cooked spaghetti, pouring in the remaining sauce. Toss everything together over low heat for about 1-2 minutes, allowing the sauce to adhere while warming the dish through. Serve immediately, garnished with optional blanched vegetables for an added touch.

Vegan Singapore Black Pepper Sauce Spaghetti Recipe FAQs
How do I choose the best cauliflower for this recipe?
Absolutely! When selecting cauliflower, look for firm heads with tightly packed florets and no dark spots or blemishes. You want a cauliflower that’s heavy for its size, indicating freshness. If cauliflower isn’t available, broccoli can be a great substitute, offering a similarly crunchy texture.
What’s the best way to store leftovers?
You can easily store leftovers in an airtight container in the fridge for up to 3 days. Be sure to keep your Vegan Singapore Black Pepper Sauce Spaghetti separate if possible to maintain its texture and flavor. When ready to reheat, just warm it gently in a skillet over medium heat.

When ready to enjoy, thaw it overnight in the fridge, then reheat gently in a skillet, adding a splash of water as needed to bring it back to life.
What if my batter doesn’t coat the cauliflower properly?
If your batter isn’t coating well, it may be too thin. You can thicken it by adding a tad more cornstarch or flour until it reaches a consistency similar to yogurt. Also, ensure your cauliflower florets are dry before dipping; moisture can prevent batter adherence.
Are there any dietary concerns or allergies I should be aware of?
Very! This Vegan Singapore Black Pepper Sauce Spaghetti is vegetarian-friendly, but be mindful of allergies related to soy or gluten if using soy sauce or all-purpose flour. If making for guests, ask about dietary restrictions; you can always swap in gluten-free alternatives like tamari or gluten-free flour.
What vegetable or protein substitutions can I make in this recipe?
The more the merrier! Feel free to swap the cauliflower with other firm vegetables like zucchini or bell peppers. If you’re looking for added protein, consider including tofu or tempeh. Just pan-fry or bake these alternatives until they achieve a lovely golden color, then toss them in with the spaghetti!
