Zippy's Oxtail Soup Recipe: Slow-Simmered Richness With Collagen-Packed Broth

This Zippy’s oxtail soup recipe delivers the deep, velvety richness that makes it a comfort food staple—slow-simmered until the oxtail falls apart and the broth becomes a collagen-packed elixir. 💛 The secret lies in patience: letting the meat tenderize over hours while aromatics build layers of umami.

I’ve perfected this version to balance traditional techniques with modern efficiency, whether you’re using a pressure cooker or a Dutch oven.

The recipe begins with a sear that locks in flavor, followed by a slow braise that transforms tough oxtail into melt-in-your-mouth bites. Star anise, cinnamon, and soy sauce create that signature depth, while ginger and garlic add brightness.

The broth reduces to a thick, glossy consistency—rich enough to coat every spoonful without being heavy. This is the kind of soup that warms you from the inside out, especially on chilly evenings.

What sets this apart is the collagen-rich broth, which develops as the oxtail simmers, releasing gelatin that gives the soup its signature silky texture. The result?

A bowl that’s both hearty and elegant, with tender meat, vibrant vegetables, and a broth so flavorful it tastes like it’s been simmering all day. Whether you’re feeding a crowd or meal prepping for the week, this recipe delivers restaurant-quality results at home.

Serve it with steamed rice or crusty bread to soak up every last drop of that precious broth. For those short on time, I’ll show you how to adapt the method using a pressure cooker—same incredible flavor, just half the wait. Let’s get cooking.

Ingredients for zippy's oxtail soup

Six pounds of oxtail, aromatic spices, and slow simmering create this velvety comfort soup.

Oxtail is the star—look for bone-in pieces at your butcher or Asian market. Costco and H Mart often carry it frozen, which works perfectly. Fresh ginger matters here; Trader Joe’s sells pre-peeled packs for convenience. Star anise and cinnamon sticks add depth but don’t overpower. If you can’t find them, ground cinnamon at half the amount works in a pinch. The tomato paste? Squeeze tubes are perfect for this recipe—no waste, and they keep for months in your pantry.

No dry sherry? White wine or even apple juice keeps the brightness. Fresh ginger too strong? Powdered ginger at one-third the amount is a decent swap. The broth is non-negotiable—low-sodium is key so you control the salt. Homemade broth gives the best flavor, but Swanson or Pacific Foods brands are solid store-bought options. For extra richness, add a splash of oyster sauce at the end. The oxtail pieces should be 2 inches long—any smaller and they’ll overcook before tenderizing.

This soup tastes even better the next day—3-4 days in the fridge with the fat skimmed off. Freezes beautifully for up to 3 months. I always make a double batch and portion it into containers. The broth reduces as it cools, so add a splash of water or broth when reheating. Garnish with cilantro right before serving—it wilts fast, so don’t add it too early.

Step-by-step instructions for Zippy's oxtail soup

This rich, slow-simmered soup delivers melt-in-your-mouth oxtail and deep, umami-packed broth.

Pat the 4 lb oxtail dry with paper towels—this ensures maximum browning. Heat a large Dutch oven over medium-high heat until hot. Working in batches (you'll need two rounds), add the oxtail pieces and sear for 3-4 minutes per side until deeply golden brown. You're building flavor here, so don't rush—wait until you see rich caramelization.

As each batch sears, remove the oxtail and set aside. In the same pot, add the 2 whole yellow onions and cook for 5 minutes until softened and lightly browned. This layer of caramelized onions will form the flavor base of your soup. The onions should smell sweet and nutty when done.

Add the 8 cloves garlic cloves and 0.5 cup fresh ginger to the pot, stirring for 30 seconds until fragrant. The ginger should release its bright, citrusy aroma, and the garlic should sizzle without burning. Immediately add the 2 whole star anise and 2 whole cinnamon sticks, letting them toast for 1 minute—this releases their essential oils and deepens the spice profile.

Stir in the 3 whole carrots and 3 whole celery stalks, cutting them with a wooden spoon if needed to break them down. Cook for 5 minutes until the vegetables soften slightly and take on the aroma of the spices. This step creates the aromatic foundation that will infuse the entire broth.

Pour in the 0.5 cup tomato paste and 0.25 cup soy sauce, stirring to scrape up all the browned bits from the bottom of the pot. This deglazing step captures all the meaty, caramelized flavors you've built. Add the 0.5 cup dry sherry and let it simmer for 2 minutes until mostly evaporated—this removes the alcohol's sharpness while adding depth.

Return all the seared oxtail pieces to the pot. Pour in the 6 cups chicken broth and bring to a gentle boil. Once boiling, reduce heat to low and add the 1.5 tsp salt and 1 tsp black peppercorns. Cover partially and simmer for 2.5 hours, stirring occasionally. The oxtail should become fork-tender, and the broth should reduce slightly, intensifying its richness.

After 2.5 hours, check the oxtail—it should be falling off the bone when tested with a fork. If not, continue simmering for another 30 minutes until tender. Discard the star anise and cinnamon sticks, then stir in the 0.25 cup chopped cilantro just before serving. The cilantro adds a bright, fresh contrast to the rich, meaty broth.

Ladle the soup into bowls and serve immediately. Each spoonful should deliver tender oxtail, velvety broth, and layers of aromatic spices. For extra richness, pass bowls of steamed jasmine rice or crusty bread on the side—this soup tastes even better when shared.

Essential equipment for this recipe

Dutch Oven Must-Have

Start with a heavy-gauge Dutch oven—I swear by Le Creuset 6-quart for its even heat distribution and durability. The deep sides prevent spills during simmering, and the tight lid traps steam to tenderize the oxtail faster.

If you’re on a budget, Lodge 5.5-quart cast iron works just as well for searing and braising. Avoid non-stick—the flavors won’t develop as deeply. 🔥

Pressure Cooker Shortcut

For a 3-hour time cut, use an Instant Pot or pressure cooker. Sear the oxtail in batches first, then transfer everything to the pot. Cook on high pressure for 60 minutes, followed by a 10-minute natural release.

The broth will still be rich, though slightly less reduced. I use Instant Pot’s sauté function for the initial sear—it mimics stovetop browning perfectly. ⚡

Immersion Blender

Skip straining with an immersion blender—I love the Ninja 1100-watt for blending the broth directly in the pot. Pulse until you reach your desired thickness, leaving some chunks for texture.

This keeps the soup’s natural richness without losing any of the meaty bits. For a smoother finish, blend in 30-second bursts while moving the blender up and down. 💫

Measuring Spoons & Tongs

Precision matters with spices: grab a set of stainless steel measuring spoons (like OXO Good Grips) for accurate star anise and cinnamon additions. Tongs—specifically J.L. Chenier 12-inch—help remove oxtail pieces from the pot without piercing them.

I also keep kitchen twine handy to tie cinnamon sticks into bundles for easy removal later. 🧂

Slow Cooker Option

For hands-off cooking, a 6-quart slow cooker works wonders. After searing, transfer everything to the pot and cook on low for 8 hours or high for 5 hours. The broth will be even more concentrated.

I recommend a Hamilton Beach 6-quart—it holds heat consistently and has a tight seal. Just skip the immersion blender and strain through a fine-mesh sieve if you prefer a smoother texture. ⏰

Garnish Tools

Fresh cilantro transforms the dish, so keep a sharp chef’s knife (like Victorinox 8-inch) and a microplane for zesting extra ginger if needed. A slotted spoon helps fish out star anise and cinnamon sticks without losing broth.

For presentation, I use tweezers to place cilantro sprigs strategically on top—it adds a pop of color and freshness. ✨
