Ingredients for ukoy recipe sweet potato panlasang pinoy
Transform humble sweet potatoes into crispy, savory-sweet ukoy with these authentic Panlasang Pinoy ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lb | Thinly sliced, 1/8-inch thick |
| Yellow Onions 🧅 | 1 whole | Thinly sliced, semi-circle shape |
| Garlic Cloves 🧄 | 6 cloves | Minced, fresh preferred |
| Vegetable Oil 🫒 | ½ cup | High smoke point for frying |
| Soy Sauce 🥄 | ¼ cup | Dark soy for color intensity |
| Cane Vinegar 🍶 | ⅛ cup | White vinegar substitute |
| Brown Sugar 🍚 | 2 tbsp | Light or dark variety |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Vegetable Broth 💧 | ½ cup | Low-sodium preferred |
| Cornstarch 🌾 | 1 tbsp | For crispy coating |
| Green Onions 🧅 | 2 whole | Chopped, for garnish |
| Sesame Oil 🫒 | 1 tsp | Toasted sesame oil |
The sweet potatoes are the star here—orange-fleshed varieties like Beauregard work best for that perfect balance of sweetness and texture. Filipino markets often carry these, but any sweet potato will do in a pinch. Thinly slicing them (about 1/8-inch thick) is key for that signature crispy crust. I always buy mine from Asian grocery stores where they're pre-sliced for ukoy, but if you're slicing yourself, use a sharp mandoline for even cuts. The onions? Yellow onions add sweetness that caramelizes beautifully during frying—red onions work too, but they'll bleed color into your dish.
No dark soy sauce? Regular soy sauce plus a pinch of sugar mimics the color and depth. Vinegar substitutes like apple cider vinegar work, but cane vinegar gives that authentic Filipino tang. The cornstarch is non-negotiable for crispiness—it creates that perfect crunchy exterior while keeping the inside tender. Want extra umami? Add a tablespoon of mushroom powder to the vegetable broth. The sesame oil should be toasted—Trader Joe's sells it pre-toasted, or lightly fry regular sesame oil in a dry pan for 2-3 minutes until fragrant. And yes, you can use regular white vinegar if that's all you've got, but cane vinegar elevates this dish to restaurant-quality.
This ukoy reheats beautifully—350°F for 5-7 minutes until crispy again. Store leftovers in an airtight container for up to 3 days, but honestly, it's best eaten fresh. For meal prep, fry in batches and store separately until ready to serve. The sauce can be made ahead and reheated separately. Garnish with green onions right before serving—they add freshness that balances the crispy, savory notes. Double the recipe if you're feeding a crowd, but keep the frying in batches to avoid overcrowding the pan.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to wash extra dishes. Sweet potatoes and onions caramelize right in the same pan where you start—no fancy equipment, just a spatula and a lid. The garlic sizzles into golden bits while the soy sauce works its umami magic, and suddenly, dinner’s ready.
- Salty-Sweet Crunch: That first bite? The edges get this irresistible crisp, almost like a cross between fries and kare-kare, while the inside stays tender. The soy sauce doesn’t overpower—it just deepens the sweetness of the potatoes, making every forkful taste like a hug from your lola’s kitchen.
- Leftover Hero: Between us, this dish begs to be made in bulk. Reheat the next day, and it’s just as good—maybe even better, because the flavors meld overnight. Pack it for work, toss it in lunchboxes, or serve it cold as a side. It’s the kind of leftovers that make you grateful for Tupperware.
- Pocket-Friendly Feast: Sweet potatoes and onions are cheap staples, and a few cloves of garlic stretch the flavor without breaking the bank. Honestly, for a dish this satisfying, it’s almost unfair how little it costs. Plus, the oil fries up fast, so you’re not wasting fuel or time waiting for a deep fryer. Win-win.
Step-by-step instructions for sweet potato ukoy Panlasang Pinoy
Here's how to transform simple sweet potatoes into crispy, golden ukoy with that perfect savory-sweet balance.
🍳 Step 1: Create the Crispy Cornstarch Coating
In a large bowl, combine the 2 lb thinly sliced sweet potatoes with 1 tbsp cornstarch, 1 tsp salt, and ½ tsp ground black pepper. Toss vigorously until every slice is evenly coated and glistening. This coating creates the signature crispy exterior we're after. Let the mixture sit for 5 minutes while you prepare the next components - this resting time helps the cornstarch adhere better to the sweet potato slices.
For best results, work in batches if needed. The slices should look dry and powdery rather than wet - this indicates proper coating. If you notice any slices sticking together, separate them gently with your hands before proceeding. This step is absolutely critical for achieving that perfect crunch we all love in ukoy.
🔥 Step 2: Fry Until Golden and Crispy
Heat ½ cup vegetable oil in a large skillet over medium-high heat until shimmering but not smoking. Working in batches to avoid overcrowding, add the coated sweet potato slices in a single layer. Fry for 3-4 minutes per side until they develop a beautiful golden brown color and appear crispy when you test a piece.
Here's the thing - don't rush this step. You'll know they're ready when the edges start to crisp and the sweet potatoes release easily from the pan. If you see any slices browning too quickly, reduce the heat slightly to prevent burning. Transfer the fried sweet potatoes to a paper towel-lined plate to drain excess oil while you prepare the sauce.
🥘 Step 3: Build the Savory-Sweet Sauce
In the same skillet (no need to clean it - those flavorful bits are gold!), add 1 whole thinly sliced yellow onion and cook for 2 minutes until softened. Add 6 cloves minced garlic and stir for 30 seconds until fragrant. Pour in ½ cup vegetable broth and let it simmer for 2 minutes until slightly reduced.
Now add ¼ cup soy sauce, 2 tbsp brown sugar, ¼ cup cane vinegar, and 1 tsp sesame oil. Stir well and let the mixture bubble gently for 3-4 minutes until it thickens slightly and coats the back of a spoon. The sauce should smell rich and complex - sweet from the sugar and vinegar, savory from the soy, and aromatic from the garlic and onions.
🍽️ Step 4: Combine and Finish
Return the crispy sweet potato slices to the skillet with the sauce. Toss gently to coat each piece evenly. Let everything simmer together for 2-3 minutes until the sweet potatoes absorb the sauce but remain crispy. The sauce should cling beautifully to the crispy exterior, creating that perfect contrast of textures.
For that final touch, sprinkle with 2 chopped green onions and give everything one last toss. The green onions add a fresh contrast to the rich, savory-sweet flavors. Serve immediately while the sweet potatoes are still crispy and the sauce is warm. This dish tastes even better when enjoyed fresh from the pan!
Pro Tips For Making Ukoy Recipe Sweet Potato Panlasang Pinoy
- Cut Potatoes Thinly: Use a mandoline or sharp knife to slice sweet potatoes ¼-inch thick—any thicker and they’ll turn mushy instead of tender-crisp. I learned this the hard way when my first batch came out like glue after frying.
- Sauté Onions Low: Cook onions on medium-low heat until translucent, not golden. High heat burns them fast, and you’ll taste bitterness in every bite—especially when mixed with soy sauce later. Patience here makes all the difference.
- Fry in Batches: Overcrowding the pan drops the oil temperature, leading to soggy potatoes. Fry in 2-inch layers with space between pieces—yes, it takes longer, but the result is that perfect crispy ukoy texture.
- Deglaze with Soy Early: After frying onions and garlic, immediately pour in 1-2 tablespoons of soy sauce while the pan’s still hot. This locks in flavor instead of waiting until the end, where it just sits on top like a sad afterthought.
Wine and beer pairings for this ukoy recipe sweet potato panlasang pinoy
Filipino-Inspired White Wine
For this sweet potato ukoy, I recommend a crisp Filipino-style white wine like Sauvignon Blanc from the Bicol region—it's bright, citrusy, and cuts through the richness beautifully. Look for Petron Wine's Sauvignon Blanc (available at Asian markets) or a New Zealand Sauvignon Blanc if you're in the US.
The acidity balances the sweetness while enhancing the garlic and vinegar notes. Serve slightly chilled (45-50°F) to refresh your palate between bites. 🍷
Light Lager for Refreshing Contrast
A Filipino lager like San Miguel Light or Red Horse works perfectly with this dish. The light body and subtle malt sweetness complement the crispy sweet potatoes without overpowering the savory-sweet sauce.
For a non-Filipino option, try a German Helles Lager—its clean, crisp profile highlights the dish's caramelized edges. Serve at 40-45°F to maintain that refreshing contrast. 🍺
Sweet Rice Wine for Authentic Pairing
For an authentic Filipino touch, serve Tuba (Filipino coconut wine) or Lambanog (a stronger coconut spirit) on the side. The natural sweetness and coconut notes mirror the dish's caramelized sweet potatoes.
If you can't find these, a lightly sweet Moscato or Riesling works as a substitute. The slight sweetness enhances the brown sugar in the sauce, creating harmony in every sip. 🥃
Non-Alcoholic Options
For a refreshing non-alcoholic pairing, try calamansi soda—a Filipino citrus soda made from calamansi (a hybrid of kumquat and orange). Its tangy-sweet flavor complements the dish's savory-sweet profile.
Alternatively, a sparkling limeade with a splash of Filipino-style vinegar (like cane vinegar) adds a zesty kick. Serve well-chilled (38-42°F) for the best experience. 💧
Beer Pairing Pro Tips
If you're using beer, avoid heavy stouts or dark ales—they'll clash with the dish's delicate flavors. Instead, opt for Filipino-style lagers or light pilsners with 4-5% ABV.
Pro tip: Let your beer breathe for 10 minutes in the glass before drinking to enhance its aroma and balance the dish's rich flavors. 🌟

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, sweet potatoes give this dish its signature caramelized sweetness and creamier texture. For the best results, use orange-fleshed sweet potatoes—they're naturally sweeter and hold up better during frying. If you must use regular potatoes, parboil them first for 2-3 minutes to prevent them from turning mushy during cooking.
How do I get the sweet potatoes extra crispy?
The secret lies in proper slicing and cornstarch coating! Slice them 1/8-inch thick using a mandoline for even cuts, then toss with cornstarch until completely dry. Fry in batches over medium-high heat for 3-4 minutes per side—don't overcrowd the pan! The cornstarch should puff up slightly and turn golden brown for maximum crunch.
What if I don't have cane vinegar?
No problem! Use white vinegar or apple cider vinegar as substitutes—they'll still provide the tangy kick needed for that authentic Filipino flavor. For best results, add an extra ½ teaspoon of sugar—this helps mimic cane vinegar's slightly sweeter profile while maintaining the dish's balance of flavors.
Can I make this ukoy ahead of time?
Yes, but with a few adjustments! Fry the sweet potatoes fresh and store them separately in an airtight container for up to 3 days. Reheat in a skillet over medium heat for 2-3 minutes** until crispy again. The sauce can be made ahead and reheated separately—just toss it with the sweet potatoes right before serving to maintain that perfect crispy texture.
What's the best way to serve this sweet potato ukoy?
This dish pairs perfectly with steamed Filipino jasmine rice to soak up all that delicious sauce! For a complete meal, serve with:
- Ginataang gulay (vegetables in coconut milk)
- Adobo (for a tangy-savory contrast)
- A simple Filipino salad with cucumbers and tomatoes The crispy sweet potatoes make an excellent standalone appetizer too—just arrange them on a platter with extra sauce for dipping!
