Main Ingredients
Beef oxtails are the main ingredient, offering rich flavor and tender meat when slowly cooked.
Fresh garlic adds savory depth, while onions provide natural sweetness. Beef broth, Worcestershire sauce, and tomato paste combine to create a flavorful brown gravy.
Ingredients
3 lbs beef oxtails
1 large yellow onion, sliced
6 garlic cloves, minced
2 cups low-sodium beef broth
2 tablespoons Worcestershire sauce
2 tablespoons tomato paste
1 tablespoon soy sauce
2 tablespoons olive oil
1 teaspoon smoked paprika
1 teaspoon dried thyme
½ teaspoon ground black pepper
½ teaspoon salt, or to taste
2 bay leaves
2 tablespoons cornstarch
2 tablespoons cold water
How to Choose Ingredients
Choose meaty beef oxtail pieces with a good balance of lean meat, connective tissue, and fat. Pieces of similar thickness will cook more evenly.
Fresh garlic provides the strongest aroma, while low-sodium beef broth allows you to control the seasoning. Tomato paste adds richness and helps deepen the color of the gravy.
Prepare the Main Ingredient
Pat the oxtails dry using paper towels. Season evenly with salt, black pepper, smoked paprika, and thyme.
Heat olive oil in a large skillet over medium-high heat. Brown the oxtails for approximately 2–3 minutes per side until a golden crust forms.
This step adds flavor and helps develop a rich gravy.
Prepare Other Ingredients
Slice the yellow onion and mince the garlic cloves.
In a mixing bowl, whisk together beef broth, Worcestershire sauce, tomato paste, and soy sauce until well combined.
Keep the bay leaves ready to add during cooking.
Step-by-Step Instructions
Step 1: Layer the Onions
Spread the sliced onions evenly across the bottom of a 6-quart slow cooker.
Step 2: Add the Oxtails
Arrange the browned beef oxtails over the onions, keeping the pieces evenly distributed.
Step 3: Add Garlic
Sprinkle the minced garlic over the meat.
Step 4: Pour the Sauce
Slowly pour the prepared beef broth mixture around the oxtails. Add the bay leaves.
Step 5: Slow Cook
Cover and cook on LOW for 8–10 hours, until the meat becomes extremely tender and pulls away easily from the bones.
Step 6: Thicken the Gravy
Carefully remove the cooked oxtails and discard the bay leaves. Skim excess fat from the cooking liquid.
Mix cornstarch with cold water and stir it into the gravy. Cover and cook on HIGH for another 15–25 minutes until thickened.
Step 7: Serve
Return the oxtails to the slow cooker and gently coat them with the gravy. Serve hot with your favorite side dishes.
Tips for Perfect Results
Browning the oxtails before slow cooking creates a deeper, richer flavor.
Avoid adding excessive broth because the beef releases natural juices during cooking.
For a smoother gravy, strain the cooking liquid before thickening. Remove excess fat for a balanced sauce.
Cook until the meat is fork-tender rather than relying only on the cooking time.
Delicious Variations
For a Southern-style version, add a teaspoon of Cajun seasoning and a dash of hot sauce.
For Caribbean-inspired flavors, add allspice, fresh ginger, scallions, and a small amount of browning sauce.
For a sweeter, richer gravy, add caramelized onions or a tablespoon of brown sugar.
You can also include carrots and mushrooms for additional flavor and texture.
Serving Suggestions
Serve these tender garlic beef oxtails over creamy mashed potatoes, steamed white rice, or buttered egg noodles.
Collard greens, roasted carrots, green beans, and warm cornbread are excellent accompaniments.
Spoon plenty of the rich brown gravy over each serving.
Meal Prep and Storage
Allow leftovers to cool and refrigerate in airtight containers within two hours.
Store refrigerated for 3–4 days or freeze for up to 3 months for best quality.
Reheat thoroughly to 165°F, adding a splash of broth if needed to loosen the gravy.
Common Mistakes to Avoid
Skipping the browning step can result in a lighter, less developed flavor.
Adding too much liquid may create a thin gravy that requires extra thickening.
Cooking for too little time can leave the oxtails chewy because the connective tissue needs sufficient time to soften.
Avoid vigorous stirring once the meat becomes tender, as it may separate from the bones.
