Ingredients for bean sprout ukoy
Golden tortillas, tender sprouts, and melty cheese—this crispy ukoy delivers restaurant-quality flavor with just a few pantry staples.
| Ingredient | Amount | Notes |
|---|---|---|
| Bean Sprouts 🌱 | 4 cups | Fresh, not canned |
| Flour Tortillas 🌯 | 6 whole | Medium size, 8-inch |
| Shredded Mozzarella Cheese 🧀 | 1 cup | Low-moisture preferred |
| Yellow Onion 🧅 | 1 whole | Thinly sliced |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Vegetable Oil 🫒 | ½ cup | High smoke point |
| Soy Sauce 🍶 | 2 tbsp | Light or regular |
| Vegetable Broth 💧 | ½ cup | Low-sodium preferred |
| White Vinegar 🍶 | 1 tbsp | For tangy balance |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Green Onion 🧅 | 2 whole | Thinly sliced, for garnish |
| Vegetable Oil Spray 🫒 | 1 tbsp | For crisping tortillas |
The tortillas are the star here. Flour tortillas work best—the corn variety can be too crumbly. Grab a pack at Trader Joe's or your local Asian market if you want to splurge on extra-thin ones. Fresh bean sprouts are a must (the canned kind just won't cut it)—look for vibrant, crisp ones at the produce section. The mozzarella should be low-moisture—it melts better and won't make your ukoy soggy. If you can't find it, shred your own from a block; pre-shredded has anti-caking agents that ruin the texture.
No soy sauce? Tamari or coconut aminos work in a pinch. Short on vegetable broth? Water plus a pinch of bouillon powder gets you close. The vinegar adds that signature tang—skip it if you're sensitive to acidity, but trust me, it's worth it. For extra crispiness, double the oil spray on the tortillas. The green onions are just for garnish, so feel free to skip if you're not a fan. Pro tip: Toast your garlic in the oil for 30 seconds before adding onions—it deepens the flavor without burning.
Tortilla strips crisp up best right after cooking, so serve immediately. Store leftovers in an airtight container for 2-3 days, but they won't be as crispy. The cheese rivers stay gooey for about 1 hour after cooking, so reheat gently in a dry pan if serving later. For extra crunch, spritz with oil and broil for 1-2 minutes before serving. This dish reheats beautifully—just toss in a hot pan with a splash of water to revive the crisp.

Step-by-step instructions for bean sprouts ukoy
Here's how to make crispy, golden tortilla crowns with gooey cheese rivers—easy enough for weeknights but impressive enough for guests.
Prepare the Cheese and Sprout Filling
In a medium bowl, combine the 4 cups bean sprouts, 1 whole yellow onion (thinly sliced), 4 cloves garlic cloves (minced), 2 tbsp soy sauce, 1 tbsp white vinegar, ½ tsp ground black pepper, and 1 tsp salt. Gently mix until everything is evenly distributed—you want the sprouts to stay fresh and crisp, not mushy. Set aside while you prep the tortillas.
In a separate small bowl, mix the 1 cup shredded mozzarella cheese with ½ cup vegetable broth. This creates a silky, stretchy cheese that will melt beautifully between the tortilla layers. The broth adds moisture to prevent dryness, which is key for that perfect ukoy texture.
Assemble the Ukoy Layers
Lay out 3 of the 6 flour tortillas on a clean surface. Place 1 tortilla in the center of each, then divide the bean sprout mixture evenly among them. Spread it out in a thin, even layer—about ⅓ cup per tortilla—leaving a 1-inch border around the edges. This ensures crispy edges when fried.
Top each with ⅓ of the mozzarella-cheese mixture, spreading it evenly over the sprouts. The cheese should be thin enough to melt completely but thick enough to create those signature rivers when cooked. Press down gently to help the cheese adhere to the sprouts.
Fold and Crimp the Tortilla Crowns
Fold the tortillas in half, then fold them in half again to form a compact square. Press the edges firmly to seal, then use your fingers to pinch and crimp the sides into decorative pleats. This step is what gives ukoy its classic crown shape—take your time to make the folds neat and even. The more secure the seal, the better the cheese will stay contained.
Repeat with the remaining tortillas until you’ve assembled all 3 ukoy pieces. If the cheese starts to soften while working, chill the assembled ukoy in the fridge for 10 minutes to help them hold their shape. This prevents the cheese from leaking out during frying.
Fry to Crispy Perfection
Heat ½ cup vegetable oil in a deep skillet over medium-high heat until it shimmers—you’re looking for a temperature around 350°F. Test it by dropping in a small piece of tortilla; if it sizzles and floats, the oil is ready. Working in batches, carefully slide the ukoy into the oil.
Fry for 3-4 minutes per side, turning gently with a slotted spoon, until the tortillas turn a deep golden brown and the cheese inside melts into glossy rivers. The key here is patience—don’t rush the frying, or the outside will burn before the cheese melts. If the oil starts to smoke excessively, reduce the heat slightly.
Serve Immediately with Fresh Garnishes
Transfer the fried ukoy to a paper towel-lined plate to drain excess oil. Let them rest for just 1 minute before serving—this helps the cheese set slightly so it doesn’t ooze out everywhere. Slice each ukoy into wedges and garnish with the 2 whole green onions (thinly sliced) for a pop of freshness and color.
Serve while hot, with extra soy sauce or a sprinkle of black pepper on the side. The contrast of crispy, golden tortillas with gooey, melted cheese and fresh sprouts makes every bite irresistible. Leftovers? Reheat in a skillet for 1-2 minutes per side to restore that crispy texture.
Pro Tips For Making Bean Sprout Ukoy
- Blanch Sprouts First: Dump raw bean sprouts into boiling water for 30 seconds before stir-frying—this softens them just enough to prevent a mushy pile while keeping their bite. I learned this the hard way after ending up with a sad, limp mess that clung to the pan like wallpaper.
- Toast Tortillas Low: Warm your tortillas over low heat for 10-15 seconds per side until pliable, not crispy—ukoy relies on them holding shape, not turning into chips. My first batch crumbled because I panicked and over-toasted them.
- Skip Pre-Slicing Onions: Toss whole onion halves (peeled, quartered) into the pan with the garlic—they’ll caramelize better and release flavor more evenly than pre-chopped pieces. Sounds weird, but it works: less mess, more depth.
- Cheese Goes Last: Sprinkle the mozzarella after the sprouts are wilted and the tortillas are stacked—this traps steam and melts it perfectly without turning it into a greasy glob. I was skeptical until I tried it (and my kids noticed the difference).
Health benefits of these flavors
Crispy Plant-Based Protein
Bean sprouts are packed with plant-based protein—about 2 grams per cup—making this ukoy a satisfying vegetarian meal. The crispy tortilla crowns add texture while the sprouts provide fiber (around 3 grams per serving) to support digestion.
This combo keeps you full longer than many fried dishes while delivering minimal saturated fat. 🌱
Rich in Vitamin K
One serving of bean sprouts delivers over 100% of your daily vitamin K needs, crucial for blood clotting and bone health. Vitamin K also helps regulate calcium, which is especially important if you're avoiding dairy but still need strong bones.
The mozzarella in this recipe adds calcium, creating a balanced nutrient profile.
Low-Calorie Comfort
At just around 250 calories per serving, this ukoy satisfies cravings without excessive calories. The high-fiber sprouts and lean tortillas help stabilize blood sugar, making it a smart choice for those monitoring carb intake. The cheese adds richness without derailing your nutritional goals when portioned correctly.
Antioxidant Boost
Bean sprouts contain flavonoids and polyphenols that combat oxidative stress in your body. The garlic in the filling adds allicin, a compound linked to heart health and immune support. Together, these ingredients create a dish that's not just delicious but actively beneficial for your well-being. 💪
Gluten-Free Adaptable
While traditional tortillas contain gluten, this recipe can easily accommodate gluten-free diets by using corn tortillas instead. The bean sprouts and cheese remain naturally gluten-free, making this ukoy a safe option for those with celiac disease or gluten sensitivity. Always check tortilla labels for cross-contamination warnings if needed.
Vegan-Friendly Option
For a fully plant-based version, replace the mozzarella with vegan cheese (like Miyoko's or Violife) or omit it entirely. Use nutritional yeast for a cheesy flavor without dairy. The soy sauce and vinegar provide enough umami to keep the dish flavorful while maintaining its health benefits.
This makes ukoy accessible to vegans while keeping all the crispy, satisfying textures. ✨

Frequently asked questions
Can I make bean sprout ukoy without cheese?
The cheese creates those signature rivers, but you can still make delicious ukoy without it. Simply layer the bean sprout mixture between tortillas and fold as directed. For extra flavor, add a sprinkle of 1 tbsp nutritional yeast or a dash of soy sauce before frying. The texture will be different but still crispy and satisfying.
What's the best way to make the tortillas extra crispy?
For maximum crispiness, use extra-thin flour tortillas and spray them generously with oil before frying. Double the oil spray amount (up to 2 tbsp per tortilla) and fry at 375°F for 4-5 minutes per side. Keep the oil hot but not smoking—this creates that perfect golden crunch while keeping the inside tender.
How do I prevent the cheese from leaking out during frying? Chill the assembled ukoy in the fridge for 10-15 minutes before frying to firm up the cheese. Also,
Can I use corn tortillas instead of flour?
Yes, but they'll be slightly more crumbly. For best results, lightly brush corn tortillas with oil before assembling. The flavor will be more authentic to traditional Filipino ukoy, though the texture may not be quite as crisp. If using corn tortillas, reduce frying time to 2-3 minutes per side to prevent burning.
What's the secret to making ukoy ahead of time?
Assemble the ukoy but don't fry it—store uncooked packages in an airtight container in the fridge for up to 24 hours. When ready to cook, fry as directed. For reheating leftovers, warm in a dry skillet over medium heat for 1-2 minutes per side to restore crispiness. The cheese may be less gooey but still delicious!
