How to Make 5-Ingredient Slow Cooker Oxtails
Step 1: Prepare the oxtails
Pat the oxtails dry with paper towels. Trim away any large, excess pieces of surface fat, if needed. For extra flavor, brown the oxtails in a hot skillet before slow cooking. This step is optional but helps develop a deeper, roasted taste.
Step 2: Add the onion
Spread the sliced onion across the bottom of the slow cooker. Arrange the oxtails on top, keeping them in an even layer as much as possible.
Step 3: Mix the cooking liquid
In a bowl, whisk together the beef broth, dry onion soup mix, and Worcestershire sauce until combined. Pour the mixture over the oxtails.
Step 4: Slow cook until tender
Cover and cook on LOW for approximately 8–10 hours, or until the meat is very tender and loosens easily from the bones. Cooking time varies with the size of the oxtails and the slow cooker, so check the texture rather than relying on time alone.
Step 5: Finish the gravy
Carefully transfer the oxtails to a serving dish. Skim excess fat from the cooking liquid if needed. For thicker gravy, transfer the liquid to a saucepan and simmer it until reduced, or thicken it separately with a cornstarch slurry. These optional finishing steps add ingredients beyond the original five.
Step 6: Serve and enjoy
Spoon the warm gravy and softened onions over the oxtails. Serve immediately with mashed potatoes, steamed rice, or another side that can absorb the rich sauce.
Helpful Tips for the Best Oxtails
- Choose pieces of similar size: This helps them cook more evenly.
- Allow enough time: Oxtails can remain tough if they haven’t cooked long enough to become tender.
- Don’t add too much liquid: The oxtails and onions release moisture as they cook.
- Watch the salt: Onion soup mix can be salty, so choose lower-sodium beef broth if preferred.
- Remove excess fat before serving: Oxtails naturally contain fat, and skimming the surface can make the gravy more pleasant.
- Use a reliable slow cooker: Follow the manufacturer’s instructions and keep the lid closed during cooking to maintain a steady temperature.
What to Serve with Slow Cooker Oxtails
Oxtails and gravy pair beautifully with creamy mashed potatoes, white rice, rice and peas, buttered egg noodles, or soft polenta. For vegetables, try collard greens, green beans, roasted carrots, or steamed cabbage.
If you want a classic comfort-food plate, serve the oxtails over rice with a generous spoonful of gravy and a side of greens. For a cozy Sunday dinner, add warm bread to help soak up the remaining sauce.
Leftovers and Storage
Allow leftovers to cool slightly and refrigerate them in airtight containers within two hours of cooking. Store in the refrigerator for 3–4 days. Reheat thoroughly to 165°F (74°C), making sure the meat and gravy are heated evenly.
Oxtails also freeze well. Store the meat with some gravy in a freezer-safe container for up to about three months for best quality. Thaw in the refrigerator before reheating.
