Ingredients You’ll Need
- 2 pound eye of round beef roast: This cut is lean yet flavorful, perfect for slow cooking. Alternatively, you can use a rump roast if you prefer a fattier cut.
- 2 tablespoons olive oil: Helps create a rich crust when searing and adds healthy fats.
- 3 stalks fresh rosemary: Fresh herbs add vibrant flavor; dried rosemary can be used in a pinch, but the potency varies.
- 4 teaspoons minced garlic: This elevates the dish with its aromatic qualities. Feel free to use garlic powder if you’re out of fresh.
- 1 teaspoon sea salt: Enhances all flavors and is essential for seasoning the beef.
- 1/2 teaspoon fresh ground pepper: Adds a subtle kick; adjust according to your taste.
- 1 tablespoon balsamic vinegar: Its tangy sweetness balances the richness of the beef and helps deglaze the pan.
How to Make Slow Cooker Roast Beef
- Prepare the Roast: Begin by rubbing the 2-pound eye of round beef roast all over with 2 tablespoons of olive oil. This creates a beautiful base for the crust.
- Mix the Seasonings: Strip the leaves from the 3 stalks of fresh rosemary and chop them finely. In a bowl, combine the chopped rosemary, 4 teaspoons of minced garlic, 1 teaspoon of sea salt, and 1/2 teaspoon of fresh ground pepper to form a fragrant mixture.
- Season the Roast: Generously rub the seasoning mixture all around the surface of the roast, ensuring it forms a nice crust.
- Sear the Roast: Preheat your skillet or multicooker to 400 ℉. Once hot, add the seasoned roast and sear it for about 4-6 minutes on each side until it’s beautifully browned.
- Deglaze the Pan: After searing, pour in 1 tablespoon of balsamic vinegar to deglaze the pan, scraping up any browned bits. This adds depth to the flavor.
- Transfer to Slow Cooker: Carefully transfer the roast and all the juices into your slow cooker, setting it on low.
- Cook: Cover and let it cook for 8-9 hours. The long, slow heat will result in tender beef that practically falls apart.
- Rest and Serve: Once done, remove the roast from the slow cooker and allow it to rest for 15-30 minutes. Slicing it at this point will yield sumptuous, perfectly juicy pieces for serving.
Storing & Reheating
If you have leftovers, you can store them in an airtight container at room temperature for a couple of hours. For longer storage, refrigerate in a sealed container for up to four days. You can also freeze the roast for up to three months. To reheat, simply warm the beef slices in a covered skillet over low heat. Alternatively, place it in the microwave for 30-60 seconds until heated through. Keep in mind that the texture might change slightly, so a splash of beef broth can help refresh it.
Chef’s Helpful Tips
- Be sure to sear the meat well; this step is crucial for developing a rich flavor.
- If you’re short on time, you can skip the searing process, but the flavor profile may not be as rich.
- Taking the roast out to rest before slicing lets the juices redistribute, resulting in more tender meat.
- Experiment with seasonings! Thyme or oregano offers a different but delightful flavor profile.
- Leftover roast beef can be repurposed in sandwiches, salads, or even stir-fries.
Savoring a dish like this Slow Cooker Roast Beef is an occasion in itself. Not only is it a simple recipe, but it also invites creativity in your meal planning. Whether enjoyed with creamy mashed potatoes or nestled in a warm sandwich, the possibilities are endless. Try different sides or dressings to make it an entirely new experience.

Recipe FAQs
What cut of beef is best for slow cooking?
The eye of round roast is ideal for slow cooking as it’s lean yet tender when cooked for a long time. You could also use a chuck roast or a brisket, which will provide a bit more fat and flavor.
Can I make this recipe without fresh herbs?
While fresh herbs offer the best flavor, you can substitute dried herbs. Use about 1 teaspoon of dried rosemary in place of fresh. You may need to adjust the quantity based on your taste preference since dried herbs can be more potent.
How do I know when the roast beef is done?
A meat thermometer is your best friend here. For medium-rare beef, look for an internal temperature of around 135 ℉, while medium should reach about 145 ℉. However, since this recipe cooks slowly, it’ll be quite tender and easy to slice even if it’s a tad above those temperatures.
Can I cook the roast on high instead of low?
Yes, you can cook the roast on high for about 4-5 hours. However, the longer cooking time on low allows for more tender meat and deeper flavors. If you’re looking for a quicker dinner, the high setting will work in a pinch.
With just a few ingredients and a little patience, you’ll have a mouthwatering dish that’s sure to impress family and friends alike. Enjoy the process, and happy cooking!
