Oxtail is the star hereālook for bone-in sections with good marbling at your butcher or Costco. The bones are what create that signature gelatinous richness. If your grocery store doesn't carry it, check the frozen section or order online. For the aromatics, fresh ginger and star anise are non-negotiableāthey build the soup's complex flavor profile. I always grab extra ginger because it loses potency fast once peeled. The soy sauces? Kikkoman light and Lee Kum Kee dark are my go-tosāthey balance sweetness and salt perfectly without overpowering.
No Shaoxing wine? Dry sherry or mirin works in a pinch, though the flavor will be slightly different. Brown sugar can be swapped for white sugar or coconut sugar, but brown adds that caramelized depth. For the stock, homemade chicken stock is ideal, but a quality low-sodium brand like Pacific Foods works too. The sesame oil is just for finishingādon't use it in the cooking or it'll turn bitter. If you're short on time, you can use pre-cut oxtail from the frozen section, but let it thaw completely before searing. The spices? Penzeys has great whole spices if you want to splurge, but regular grocery store versions work fine for this recipe.
This soup tastes even better the next day as flavors meld. Store in the fridge for up to 5 daysāthe broth will continue to develop. For freezing, portion into airtight containers and keep for 3 months. I always make a double batch because it reheats beautifully and makes amazing leftovers. When reheating, bring it to a gentle simmerānever boil or the broth will separate. Garnish with fresh green onions and a drizzle of sesame oil right before serving for that restaurant-quality touch.

Step-by-step instructions for Asahi Grill oxtail soup
Here's how to unlock that signature Asahi Grill richness through slow, layered flavors.
š„ Step 1: Sear the Oxtail for Deep Flavor
Heat a large Dutch oven over medium-high heat until smoking hot. Add the 3 lb oxtail sections in batches, working in 2 batches if needed, and sear for 3-4 minutes per side until deep golden brown. This caramelization forms the flavor foundation.
Don't overcrowd the panāyou want those pieces to develop that rich crust. If the pan gets too crowded, reduce heat slightly to prevent steaming instead of searing. Transfer seared oxtail to a plate as you work.
šØāš³ Step 2: Build the Aromatic Base
In the same Dutch oven, add 2 tablespoons sesame oil and let it shimmer for 30 seconds. Add 2 whole yellow onion cut into even chunks and cook for 5 minutes until softened and golden. Stir in 2 tablespoons finely grated fresh ginger and 8 smashed garlic cloves, cooking for another 2 minutes until fragrant.
Here's where the magic starts: add 4 lightly crushed star anise pods, 2 cinnamon sticks, and 2 dried bay leaves. These spices will infuse the broth with complex, warming notes. Stir everything together and cook for 1 minute to bloom the aromatics.
š„ Step 3: Deglaze and Combine All Ingredients
Pour in 0.5 cup Shaoxing wine and scrape up all those beautiful browned bits from the bottom of the pot with a wooden spoon. This deglazing step captures all that concentrated flavor. Let the wine simmer for 2 minutes until reduced by half.
Add 6 cups chicken stock, 0.5 cup light soy sauce, 1 tablespoon dark soy sauce, 0.25 cup packed brown sugar, 1.5 teaspoons kosher salt, and 0.5 teaspoon freshly cracked black peppercorns. Return the seared oxtail to the pot, making sure it's fully submerged. Bring everything to a gentle boil.
ā° Step 4: Slow Simmer for Maximum Tenderness
Reduce heat to low and cover partially with a lid. Let the soup simmer gently for 2.5-3 hours until the oxtail is fork-tender and falls off the bone easily. I check for doneness by inserting a forkāit should slide in with minimal resistance.
During this time, the collagen in the oxtail will break down into gelatin, creating that signature rich, velvety broth. If the liquid reduces too much, add hot water 1 cup at a time to maintain proper consistency. The spices should be fully infused but not bitter.
š½ļø Step 5: Finish and Serve with Confidence
Remove the oxtail and strain the broth through a fine-mesh sieve into a clean pot. Discard the solids or save for stock. Return the broth to the pot and bring to a gentle simmer. Stir in 1 tablespoon toasted sesame oil and adjust seasoning if needed.
Return the oxtail to the broth and simmer for another 10 minutes to reheat. Ladle the soup into bowls and garnish with 0.25 cup sliced green onions. Serve immediately with steamed riceāeach spoonful should deliver that perfect balance of rich, umami-packed broth and tender, gelatinous oxtail.
Pro Tips For Making Asahi Grill Oxtail Soup
- Brown the Oxtail First: Donāt skip the searāthis is where the flavor hides. Hit the oxtail sections hard in a hot pot with oil until deep brown, about 5-7 minutes per side. I used to rush this, and the soup always tasted flat. Patience here makes a real difference.
- Peel and Slice Ginger Thin: Star anise and garlic get all the love, but ginger is the backbone. Use a mandoline or knife to slice it paper-thināno need to peel if itās fresh. Thick chunks just sit like rocks. (Yes, even if youāre impatient like me.)
- Simmer Low and Long: After the initial sear and aromatics, drop the heat to a bare simmerājust tiny bubbles breaking the surface. Oxtail needs 2+ hours to fall apart, and boiling it will turn the broth cloudy. I learned this the hard way after a rushed dinner.
- Toss Star Anise Early: Add the star anise pods with the onions and ginger, not later. They need time to infuse the broth deeplyāat least 30 minutes before serving. Skip this, and youāll just have a faint aftertaste instead of a rich, aromatic base.
Creative variations of this recipe
Spicy Sichuan Twist
Add 1 tbsp Sichuan peppercorns (toasted and crushed) and 1 tsp chili bean paste when building the aromatic base. The numbing heat of Sichuan peppercorns pairs beautifully with the rich oxtail. I like to finish with thinly sliced red chili oil (about 1 tsp per bowl) right before serving. This version has a crowd-pleasing kick that still lets the umami shine through. š¶ļø
Creamy Coconut Fusion
Swap out the chicken stock for 6 cups coconut milk (full-fat preferred) and add 1 can (14 oz) crushed tomatoes with the aromatics. The coconut milk creates a naturally creamy texture while balancing the richness of the oxtail. Garnish with toasted coconut flakes and lime wedges for a Thai-inspired twist that's surprisingly refreshing. š„„
Mushroom & Thyme Elevation
SautĆ© 1 lb shiitake mushrooms (sliced) with the onions and add 1 tbsp fresh thyme when building the aromatic base. The earthy mushrooms deepen the umami profile while thyme adds a bright herbal note. For extra richness, stir in 2 tbsp mushroom powder when combining all ingredients. This version feels luxurious without requiring special ingredients. š
Quick Pressure Cooker Adaptation
For a faster version, use a 6-quart electric pressure cooker. Sear the oxtail as directed, then combine all ingredients and cook on high pressure for 45 minutes. Release pressure naturally, then finish with the sesame oil and green onions. The pressure cooker cuts the simmering time by 75% while still delivering that signature gelatinous texture. Perfect for busy weeknights when you crave restaurant-quality soup. ā”
Vegetarian Oxtail Substitute
Replace the oxtail with 3 lb king oyster mushrooms (whole) or 2 lb extra-firm tofu (pressed and cubed). For the gelatinous texture, add 1 tbsp agar-agar with the broth. The mushrooms absorb flavors beautifully while tofu provides a meaty texture. Boost umami with 2 tbsp vegetarian oyster sauce instead of soy sauce. This version proves you don't need meat for deep, satisfying flavors. š±
Winter Comfort Version
Add 1 small parsnip (peeled and diced) and 1 small sweet potato (peeled and cubed) with the onions. The natural sweetness of these root vegetables complements the oxtail beautifully. Finish with a sprinkle of toasted pumpkin seeds for crunch and a drizzle of maple syrup (about 1 tsp per bowl**) for extra warmth. This version feels like a cozy hug in a bowl during chilly months. āļø

Frequently asked questions
How do I know when the oxtail is fully tender?
Use the fork test: insert a fork into the largest piece of oxtail. If it slides in with minimal resistance and the meat falls apart easily, it's done. Typically takes 2.5-3 hours of simmering, but timing depends on your stove's heat consistency. The broth should also be thickened with gelatinous richness.
Can I substitute beef short ribs for oxtail?
While possible, oxtail's collagen-rich bones create that signature velvety texture. If substituting, use 3 lb beef short ribs and add 1 tbsp cornstarch to the broth at the end to mimic gelatin. The flavor will be meatier but less luxurious. For best results, stick with oxtail for that authentic Asahi Grill experience.
Why did my broth turn cloudy during cooking?
Cloudiness usually means the soup boiled too vigorously, breaking down the collagen prematurely. Reduce heat to maintain a gentle simmer and skim any foam that rises. If it happens, strain the broth again through a fine-mesh sieve before serving. The spices (especially star anise) can also contribute slight cloudinessājust taste and adjust seasoning.
How can I make this soup ahead of time?
This soup tastes even better the next day! Store in an airtight container in the fridge for up to 5 days, or freeze for 3 months. Reheat gently on low heatānever boil or the broth will separate. The flavors meld beautifully overnight, making it perfect for meal prep.
What's the secret to balancing the flavors?
The key is layering: start with sweetness from brown sugar, add umami from soy sauce, and finish with acidity from Shaoxing wine. Taste as you goāadjust salt in 0.5 tsp increments and balance with a splash of rice vinegar if needed. The spices should enhance, not overpower.
