Step‑by‑Step Instructions for Savory Slow-Cooker Roast Beef
Step 1: Sear the Beef and Aromatics
Begin by heating a frying pan over medium-high heat. Once hot, add a drizzle of vegetable oil, then carefully place the topside beef roast in the pan. Sear for about 3–4 minutes on each side until nicely browned. Toss in the halved garlic bulb and onions, browning them for an additional 2 minutes. After searing, transfer the beef and aromatics to your slow cooker.
Step 2: Create the Flavorful Base
In the same frying pan, pour in 500 ml of beef stock and bring it to a gentle boil while scraping up the browned bits from the bottom of the pan; this will enrich your dish. Whisk in 1 tablespoon of brown miso paste and 1 tablespoon of tomato purée until well combined, forming a savory mixture. Pour this concoction over the beef in the slow cooker, ensuring it covers the roast.
Step 3: Add the Herbs and Spice It Up
Next, add 1 teaspoon of black peppercorns, 3 whole bay leaves, and 2 sprigs of rosemary into the slow cooker, creating a fragrant blend. This step is crucial for infusing the savory slow-cooker roast beef with robust flavors. Secure the lid and set your slow cooker on high for 1.5 to 1.75 hours, or opt for low for 2 hours and 20 minutes, until the beef reaches an internal temperature of 60°C (140°F).
Step 4: Resting the Beef for Tenderness
Once cooked, carefully remove the lid and let the beef rest in the cooker for about 30–40 minutes, still covered. This resting period allows the juices to redistribute throughout the meat, ensuring that your savory slow-cooker roast beef is not only tender but oh-so-juicy and full of flavor.
Step 5: Prepare the Gravy
After resting, strain the cooking liquor into a saucepan, pressing on the onions to extract maximum flavor. Discard the solids and skim off any excess fat. In a separate bowl, mix 2 tablespoons of cornflour with 4 tablespoons of the strained liquid to create a smooth slurry. Stir this back into the saucepan with the remaining cooking liquor.
Step 6: Thicken the Gravy and Serve
Heat the gravy mixture over medium heat, stirring it continuously for about 10–15 minutes until it thickens into a creamy consistency. This rich gravy will beautifully complement your savory slow-cooker roast beef. Serve it alongside your preferred sides, like creamy mashed potatoes or roasted vegetables, for a truly comforting meal.
