Ingredients You’ll Need
- 2 pound eye of round beef roast or rump roast: This cut of beef is flavorful and becomes incredibly tender when slow-cooked. If you prefer, the chuck roast is another excellent option that offers a richer taste.
- 2 tablespoons olive oil: Used to give the roast a succulent outer layer, olive oil adds depth without being overpowering. You can substitute with vegetable oil or grapeseed oil if preferred.
- 3 stalks fresh rosemary: Fresh herbs bring a vibrant flavor that dried herbs can’t match. If rosemary isn’t on hand, consider using thyme or oregano as alternatives.
- 4 teaspoons minced garlic: Garlic amplifies the savory notes of the roast. Fresh minced garlic delivers the best flavor, but you can use jarred if you’re in a pinch.
- 1 teaspoon sea salt: Salt brings out the natural flavors of the beef. You can adjust the amount to your taste, but remember that a little goes a long way.
- 1/2 teaspoon fresh ground pepper: Freshly ground black pepper adds a subtle heat to balance the dish. If you don’t have whole peppercorns, pre-ground works just as well!
- 1 tablespoon balsamic vinegar: Balsamic vinegar acts as a delightful glaze and assists in tenderizing the meat. White wine vinegar can be a good substitution, but it will alter the flavor slightly.
How to Make Slow Cooker Roast Beef
- Prepare the Roast: Rub 2 tablespoons of olive oil all over the 2-pound eye of round beef roast. Ensure every inch is coated for optimum flavor and moisture.
- Season the Meat: Remove leaves from the 3 stalks of fresh rosemary and chop finely. In a small bowl, combine chopped rosemary with 4 teaspoons of minced garlic, 1 teaspoon of sea salt, and 1/2 teaspoon of fresh ground pepper. Rub this seasoning mix generously around the outside of the roast until a crust is formed.
- Sear the Roast: Preheat your skillet or multicooker to 400°F. Add the seasoned roast to the pan and sear on each side until lightly browned, approximately 4-6 minutes. This step locks in flavors and improves the texture.
- Deglaze and Transfer: After searing, carefully deglaze the pan by adding 1 tablespoon of balsamic vinegar. Scrape the bottom of the skillet to lift any flavorful bits. Transfer the roast and all pan contents into the slow cooker.
- Slow Cook: Cover and cook your roast on low for 8-9 hours. The meat should be fork-tender and infused with savory notes by the end of the cooking time.
- Rest and Serve: Once done, remove the roast from the slow cooker and let it rest for about 15-30 minutes. Slice to serve and enjoy the amazing flavors!
Storing & Reheating
Leftover Slow Cooker Roast Beef should be stored in the refrigerator within two hours of cooking. Store it in an airtight container, where it can stay fresh for up to four days. Alternatively, you can freeze the roast by wrapping it tightly in plastic wrap and then placing it in a freezer-safe bag; it will hold up to 3 months. When you’re ready to enjoy, thaw the roast overnight in the fridge and reheat it in the oven at 325°F for 20-30 minutes. Just remember, the texture may vary slightly, but you can refresh it by adding a splash of beef broth during reheating.
Chef’s Helpful Tips
- Avoid overcooking: Monitor the time carefully, as cooking much longer than necessary will dry out the meat.
- Searing is essential: Don’t skip the searing step! It creates a flavorful crust and enhances the depth of flavor.
- Meat temperature matters: Allow your roast to come to room temperature for about 30 minutes before cooking for even cooking.
- Adjust seasoning: Remember, you can always taste and adjust seasonings before cooking, especially if your palette is calling for a bolder flavor.
Slow Cooker Roast Beef is more than just a meal; it’s a warm hug on a plate. With its juicy tenderness and amazing aromas, each bite brings comfort and satisfaction. Don’t hesitate to experiment with different herbs and spices to make it your own. Enjoy the magic of slow cooking and invite your taste buds to feel right at home!
