The sweet potatoes are the heart of this dishâchoose firm, vibrant orange ones with no soft spots. Filipino markets often carry the best varieties, but most grocery stores have them too. For the celery crowns, select crisp stalks with no browning. The peanut butter should be natural and unsweetenedâbrands like Smucker's or Jif Natural work perfectly. Toasting the mustard seeds in the oil is non-negotiable; this step unlocks their nutty aroma that defines the dish's signature flavor profile.
No fish sauce? Soy sauce or coconut aminos work in a pinch, though the umami depth won't be identical. Substituting coconut milk with cashew cream maintains creaminess but alters texture slightly. For the celery crowns, if you can't find thin celery sticks, julienne-cut celery achieves the same crispy result. The brown sugar can be swapped for coconut sugar for a more authentic Filipino touch. All spices should be freshly toasted if possibleâPenzeys Spices carries excellent whole spices for this purpose.
Store sweet potatoes in a cool, dark place for up to 5 days after peeling. The celery crowns should be made fresh or stored separately in the fridge for 2 days maximum to maintain crispness. The peanut stew keeps well in the fridge for 4-5 daysâreheat gently with a splash of coconut milk to restore creaminess. For meal prep, portion the stew separately and assemble with potatoes just before serving to preserve the celery's crunch.

Step-by-step instructions for sweet potato kong
Master the perfect balance of crispy celery crowns and velvety sweet potato sauce with this method.
đ„ Step 1: Roast Sweet Potatoes for Silky Texture
Preheat your oven to 400°F and line a baking sheet with parchment paper. Toss the 2 lb sweet potatoes (peeled and cut into 1-inch cubes) with 0.25 cup vegetable oil and 1.5 tsp salt until evenly coated. Spread them in a single layer on the prepared sheetâthis prevents steaming and ensures crisp edges.
Roast for 25-30 minutes until the sweet potatoes are tender when pierced with a fork but still hold their shape. You want them to caramelize slightly on the edges while maintaining a creamy interior. Real talk: If you see them browning too quickly, tent with foil to prevent burning while they finish cooking.
đšâđł Step 2: Prepare the Mustard Seed Base
While the sweet potatoes roast, heat 0.25 cup vegetable oil in a large skillet over medium heat. Add the 1 tbsp mustard seeds and toast them for 1-2 minutes until they release their nutty aroma and turn golden. Here's the thingâdon't walk away. Mustard seeds burn faster than you think.
Remove the mustard seeds with a slotted spoon and set aside. In the same skillet, add 1 medium yellow onions (diced) and 6 cloves garlic (minced). Sauté for 5-6 minutes until the onions are translucent and the garlic is fragrant. This aromatic base forms the flavor foundation for your sauce.
đł Step 3: Build the Creamy Peanut-Coconut Sauce
To the skillet with onions and garlic, add the toasted mustard seeds, 0.5 cup peanut butter, 2 tbsp brown sugar, 1 tbsp fish sauce, 1 whole cinnamon stick, and 2 whole bay leaves. Stir to combine, then pour in the 1 can (13.5 oz) coconut milk and 0.5 tsp black pepper. Bring to a gentle simmer over medium-low heat.
Simmer for 8-10 minutes until the sauce thickens slightly and coats the back of a spoon. You're aiming for a velvety consistencyânot too thick, but not watery either. Taste and adjust seasoning: add more fish sauce for umami, brown sugar for sweetness, or salt for balance. This is where the magic happensâwhere all the flavors meld into that perfect creamy bliss.
đ„ Step 4: Create Crispy Celery Crowns
While the sauce simmers, prepare the celery crowns. Cut the 1 bunch celery sticks into 2-inch lengths and separate the strings (the leafy tops) from the stalks. Blanch the celery stalks in boiling water for 30 seconds, then immediately transfer to an ice bath to stop cooking. This step ensures they stay crisp when fried.
Heat 0.25 cup vegetable oil in a clean skillet over medium-high heat until shimmering. Fry the celery stalks in batches for 2-3 minutes per side until golden brown and crisp. Remove and drain on paper towels. For the crowns, fry the celery strings in the same oil for 1 minute until just crispâdon't overcook or they'll turn bitter.
đœïž Step 5: Assemble and Serve
Transfer the roasted sweet potatoes to a large bowl and mash them slightly with a potato masher or forkâyou want some texture, not a puree. Pour the warm peanut-coconut sauce over the sweet potatoes and stir gently to combine. The sauce should coat the sweet potatoes evenly, creating that signature creamy texture.
Serve immediately over 2 cups steamed white rice, garnished with crispy celery crowns and strings on top. The contrast of temperatures and textures is what makes this dish extraordinaryâcreamy, warm sweet potatoes with crisp, cool celery crowns. Each bite delivers that perfect balance of sweet, savory, and umami flavors.
Pro Tips For Making Sweet Potato Kong
- BOIL POTATOES UNTIL TENDER: Skip the mushy mess by testing doneness with a forkâit should slide in like butter, not fight you. Overcooking turns them to glue; undercooking leaves you chewing celery sticks. Aim for 15-18 minutes in salted water (yes, even if youâre impatient like me).
- TOAST PEANUT BUTTER FIRST: Warm the peanut butter with the coconut milk for 2 minutes before adding mustard seedsâthis prevents a weird, beany aftertaste. I learned this the hard way when my first batch tasted like a failed science experiment.
- DONâT SKIP THE CELERY CHAR: Sear the celery sticks in oil for 3-4 minutes until they darken slightlyâthis adds depth that raw celery never will. Itâs the thing that makes this dish taste like a proper kong, not just a sweet potato side.
- USE FULL-FAT COCONUT MILK: The creaminess mattersâlight coconut milk will make your sauce separate like oil and water. I was skeptical until I tried it; now I refuse to go back. (Your future self will notice the difference.)
Pro cooking tips for great sweet potato kong
Perfect Roasting Technique
Sweet potatoes need 400°F oven heat and 1-inch cubes for even cooking. Toss them with 0.25 cup vegetable oil and 1.5 tsp salt before spreading in a single layerâthis prevents steaming and creates crisp edges.
Roast for 25-30 minutes until tender but still holding shape. I swear by this method because it caramelizes the edges while keeping the insides creamy. đ„
Mustard Seed Toasting
Never skip toasting the 1 tbsp mustard seedsâthis unlocks their nutty aroma that defines the dish. Heat 0.25 cup vegetable oil over medium heat and toast for 1-2 minutes until golden.
Watch closelyâthey burn faster than you'd expect. Set aside immediately after toasting to preserve their freshness for the sauce. đĄ
Sauce Consistency Secrets
The peanut-coconut sauce should coat the back of a spoon but remain silky, not gluey. Simmer for 8-10 minutes over medium-low heat after adding all ingredients. I recommend tasting and adjusting with fish sauce (for umami) or brown sugar (for sweetness) right before serving.
The sauce thickens as it cools, so don't over-reduce it. âš
Celery Crown Crispiness
Blanching the celery stalks for 30 seconds before frying is non-negotiable for crispness. Fry in batches at 350°F for 2-3 minutes per side until golden brown.
For the celery strings, fry for just 1 minuteâovercooking turns them bitter. Keep them warm in a 200°F oven while you assemble the dish. đ
Assembly Timing
Assemble the dish immediately after frying the celery crowns to maintain their crispness. Pour the warm sauce over the roasted sweet potatoes and gently mash them to create texture.
The contrast between the creamy sweet potatoes and crisp celery crowns is what makes this dish unforgettable. Serve right away with steamed rice for the full experience. đ
Flavor Balancing
Taste your sauce before serving and adjust with fish sauce (for saltiness), brown sugar (for sweetness), or black pepper (for heat). The key is balanceâFilipino dishes often have layers of sweet, salty, and umami.
I like to add a pinch of cinnamon at the end for warmth. Trust your palate and adjust to your taste. đȘ

Frequently asked questions
Can I make this recipe without fish sauce?
For a vegan version, replace the 1 tbsp fish sauce with 1 tbsp soy sauce or coconut aminos. The umami flavor will be slightly different but still delicious. If you're avoiding soy, try 1 tbsp mushroom sauce for depth. The key is balancing the saltinessâadjust with extra brown sugar if needed.
How do I store leftovers?
Store the peanut-coconut sauce separately from the sweet potatoes in airtight containers for up to 4-5 days in the fridge. Reheat the sauce gently with a splash of coconut milk to restore creaminess. For the sweet potatoes, keep them in a separate container to maintain texture. The celery crowns should be eaten fresh or stored separately for 2 days maximum to preserve crispness.
Can I use regular potatoes instead of sweet potatoes?
Not recommended! Sweet potatoes have a natural sweetness and creamier texture that pairs perfectly with the peanut sauce. Regular potatoes would absorb too much liquid and lose their structure. If you must substitute, try purple sweet potatoes for a beautiful color contrast, but the flavor won't be identical.
What's the best way to reheat this dish?
Reheat the sauce and sweet potatoes separately in a saucepan over low heat with a splash of coconut milk or water to prevent drying. For the celery crowns, warm them in the oven at 350°F for 3-5 minutes to restore crispness. Combine everything just before serving to maintain the perfect texture contrast.
Can I make this dish in a slow cooker?
Yes, but with adjustments! Roast the sweet potatoes separately first, then transfer them to the slow cooker with the sauce ingredients. Cook on low for 3-4 hours instead of simmering on the stovetop. The sauce may thicken more, so add a splash of coconut milk if needed. The celery crowns will need to be made fresh and added just before serving.
