Ingredients
For the Beef Oxtails
4 pounds beef oxtails, cut into sections
1 large yellow onion, thinly sliced
3 cups low-sodium beef broth
1 tablespoon olive oil, for browning the meat (optional)
For the Seasoning
1 teaspoon kosher salt, or to taste
1 teaspoon freshly ground black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon smoked paprika
1/2 teaspoon dried thyme
1/2 teaspoon dried rosemary
For the Rich Brown Gravy (Optional)
2 tablespoons cornstarch
2 tablespoons cold water
Ingredient Note: The beef, onion, and broth form the three main ingredients. The seasonings and optional gravy thickener add extra flavor and help create a richer finished dish.
Instructions
Step 1: Prepare the Beef Oxtails
Pat the beef oxtails dry with paper towels. Removing excess moisture helps the meat brown more effectively.
Trim away any large, excessive pieces of surface fat if necessary, leaving enough fat to keep the meat flavorful during cooking.
In a small bowl, combine the salt, black pepper, garlic powder, onion powder, smoked paprika, dried thyme, and dried rosemary.
Sprinkle the seasoning mixture evenly over the beef oxtails, turning the pieces to coat all sides.
Step 2: Brown the Meat (Optional)
Heat the olive oil in a large skillet over medium-high heat.
Working in batches, brown the oxtails for approximately 3–4 minutes per side, until they develop a deep golden-brown crust.
Transfer the browned oxtails to a plate.
Although browning is optional, it adds extra depth and a more complex, savory flavor to the finished gravy.
Step 3: Add the Onions to the Slow Cooker
Spread the sliced onions across the bottom of a 6-quart or larger slow cooker.
Arrange the seasoned beef oxtails on top of the onions, stacking the pieces as needed to fit.
Pour the beef broth around the meat.
The broth does not need to completely cover the oxtails. The slow cooker will retain moisture as the beef cooks.
Step 4: Slow Cook Until Tender
Cover the slow cooker with its lid.
Cook on LOW for 8–10 hours or HIGH for 5–6 hours, depending on the size and thickness of the oxtails and your appliance.
Avoid lifting the lid unnecessarily, as doing so allows heat to escape and may extend the cooking time.
The oxtails are ready when the meat is fork-tender and easily separates from the bones. If the meat is still tough, continue cooking and check again after 30–60 minutes.
Step 5: Prepare the Brown Gravy
Once the oxtails are tender, carefully transfer them to a serving platter and keep them warm.
Skim excess fat from the cooking liquid if desired.
For thicker gravy, pour the cooking liquid into a saucepan and bring it to a gentle simmer.
In a small bowl, whisk together the cornstarch and cold water until smooth.
Slowly whisk the slurry into the simmering liquid. Cook for 1–3 minutes, stirring frequently, until the gravy thickens.
Taste and adjust the seasoning if necessary.
Important: If using cornstarch to thicken the gravy, do not add it directly to the slow cooker as a dry powder. Mixing it with cold water first helps prevent lumps.
Step 6: Serve and Enjoy
Return the tender oxtails to the gravy or arrange them on a large serving platter.
Spoon the warm brown gravy over the meat, making sure each piece is coated with the rich cooking juices.
Serve immediately with your favorite side dishes for a comforting, satisfying meal.
Tips for the Best Slow Cooker Beef Oxtails
Choose the Right Oxtails
Look for meaty oxtail sections with a good balance of meat, connective tissue, and bone. These characteristics help create a rich cooking liquid and tender finished meat.
Do Not Rush the Cooking Process
Oxtails contain substantial connective tissue that needs time to soften. If the meat is still tough, it usually needs more cooking rather than less.
Brown for Deeper Flavor
Searing the oxtails before slow cooking creates browned surfaces that contribute additional savory flavor to the finished dish.
Control the Gravy Consistency
For thinner gravy, serve the cooking liquid as it is. For a thicker sauce, use the cornstarch slurry and simmer until the desired consistency is reached.
Remove Excess Fat
Oxtails can release a considerable amount of fat during cooking. Skimming the surface before preparing the gravy helps produce a smoother, less greasy sauce.
Make It Your Own
For a slightly different flavor profile, add a splash of Worcestershire sauce or a small amount of tomato paste. These additions are optional and will change the recipe from its basic three-main-ingredient version.
What to Serve with Beef Oxtails
These tender slow cooker beef oxtails pair beautifully with a variety of classic comfort food sides.
Creamy Mashed Potatoes: Their smooth texture makes them ideal for soaking up the rich brown gravy.
Steamed White Rice: A simple, satisfying option that allows the savory beef flavor to shine.
Buttered Egg Noodles: Their tender texture works wonderfully with the slow-cooked meat and sauce.
Roasted Vegetables: Carrots, green beans, Brussels sprouts, or broccoli add color and balance to the plate.
Southern-Style Collard Greens: Their savory flavor complements the richness of the oxtails.
Cornbread: Serve warm cornbread alongside the meal for a comforting, home-style dinner.
Storage Instructions
Refrigeration
Allow the cooked beef oxtails to cool slightly, then transfer them to shallow, airtight containers with some of the gravy.
Refrigerate within 2 hours of cooking. Store at 40°F (4°C) or below and use within 3–4 days.
Freezing
For longer storage, place the cooled oxtails and gravy in freezer-safe containers or heavy-duty freezer bags.
Remove excess air, label with the date, and freeze for up to 3 months for best quality.
Thaw frozen oxtails in the refrigerator overnight before reheating.
How to Reheat Beef Oxtails
Stovetop Method
Place the oxtails and gravy in a saucepan over medium-low heat.
Cover and heat gently, stirring occasionally and adding a little beef broth or water if the gravy becomes too thick.
Continue heating until the meat and gravy reach an internal temperature of 165°F (74°C).
Microwave Method
Place an individual serving in a microwave-safe dish and add a spoonful of gravy.
Cover loosely with a microwave-safe lid and heat in short intervals, stirring or turning the meat as needed, until the entire serving reaches 165°F (74°C).
Oven Method
Place the oxtails and gravy in an oven-safe dish. Cover tightly with foil and heat at 325°F (163°C) until thoroughly hot, checking that the center reaches 165°F (74°C).
Frequently Asked Questions
Are Beef Oxtails Better in a Slow Cooker?
A slow cooker is an excellent choice for beef oxtails because its low, steady heat allows the connective tissue to soften gradually. This produces tender meat and flavorful cooking juices with minimal supervision.
Why Are My Beef Oxtails Still Tough?
Oxtails may remain tough if they have not cooked long enough. Continue cooking until the meat becomes fork-tender and separates easily from the bone. Cooking times vary depending on the size of the pieces and the slow cooker.
Do I Need to Brown the Oxtails First?
No. Browning is optional, and the recipe can be prepared without it. However, searing the meat before slow cooking adds extra color and depth of flavor.
Should the Beef Oxtails Be Completely Covered with Broth?
No. The broth does not need to cover the meat completely. A slow cooker retains moisture during cooking, and the oxtails will release additional juices as they become tender.
Can I Make Beef Oxtails Ahead of Time?
Yes. Cook the oxtails a day ahead, refrigerate them with the gravy, and reheat thoroughly before serving. Chilling also makes it easier to remove solidified excess fat from the surface.
Can I Make the Gravy Thicker?
Yes. Simmer the cooking liquid in a saucepan and add a cornstarch slurry made with equal parts cornstarch and cold water. Add it gradually until the gravy reaches your preferred consistency.
