Ingredients

- 3 lbs beef sirloin tip roast
- 2 tablespoons olive oil
- 1 tablespoon kosher salt
- 1 teaspoon black pepper
- 3 cloves garlic, minced
- 1 large onion, sliced
- 1 cup beef broth
- 1 tablespoon Worcestershire sauce
- 2 teaspoons dried thyme
Equipment Needed
- Slow cooker
- Large skillet
- Sharp knife
- Cutting board
Instructions

Step 1: Prepare the Roast
Trim any excess fat from the beef sirloin tip roast using a sharp knife. Generously season the roast with kosher salt and black pepper on all sides. This crucial step enhances flavor. Allow the seasoned roast to rest at room temperature for about 15 minutes. This brief period helps the meat cook more evenly in the slow cooker.
Step 2: Sear the Roast
Heat olive oil in a large skillet over medium-high heat. Once hot, add the roast to the skillet. Sear each side for about 3-4 minutes until a golden-brown crust forms. Don’t rush this process, as it locks in juices and enhances flavor. Transfer the seared roast carefully to your slow cooker.
Step 3: Prepare Aromatics
In the same skillet used for searing, add minced garlic and sliced onion. Sauté for about 2-3 minutes until the onion becomes translucent. This step deglazes the pan and captures all the flavor. Once done, add the onion and garlic mixture to the slow cooker, spreading it evenly over the roast.
Step 4: Add Liquid Ingredients
Pour beef broth and Worcestershire sauce into the slow cooker, careful to evenly distribute liquids around the roast. Sprinkle dried thyme over the top. These liquids and herbs infuse the roast, creating a deep, rich flavor that permeates the meat over time. Cover the slow cooker with the lid.
Step 5: Slow Cook the Roast
Set your slow cooker on low and cook the roast for 6-8 hours. As the hours pass, the beef will become increasingly tender; test with a fork to check tenderness. If easily pierced, it’s ready. Before serving, taste and adjust seasoning if desired. The long, low-temperature cooking enhances tenderness and retains moisture.
Step 6: Rest and Serve
Once the roast reaches desired tenderness, remove it from the slow cooker and let it rest on a cutting board for about 10 minutes. Resting allows the juices to redistribute, ensuring each slice is succulent and juicy. Slice against the grain for the best texture, and serve with the slightly thickened broth and onions spooned over.
Tips and Tricks
To achieve an even deeper flavor, add a splash of red wine to the broth mix. A teaspoon of Dijon mustard can add a slight tang when mixed into the liquids. If time allows, marinate the beef with the seasonings and oil overnight for enhanced depth. For a thicker sauce, consider adding a slurry of cornstarch and water in the last hour of cooking.
Recipe Variations
- Add root vegetables like potatoes and carrots for a complete meal.
- Use balsamic vinegar instead of Worcestershire for a tangy twist.
- Sprinkle red pepper flakes for a slight kick of heat.
- Replace beef broth with mushroom broth for a depth of flavor.
Frequently Asked Questions
Can I use a frozen roast? It’s best to use thawed meat for even cooking. A frozen roast will increase cooking time and may result in uneven tenderness.
Is it necessary to sear the roast? Searing locks in juices and improves flavor, but it’s not necessary. Skipping this step will save time, though the roast may be slightly less flavorful.
How can I tell if my roast is done? Use a meat thermometer; the internal temperature should reach at least 145°F. Alternatively, when the roast is fork-tender, it’s ready.
Can I cook on high? Cooking on high reduces the time to 3-4 hours but may compromise tenderness. Low and slow is recommended for the best result.
