How to make Slow Cooker Roast Beef Dinner

Making a Slow Cooker Roast Beef Dinner is straightforward and requires minimal hands-on time. With just a few simple ingredients, you can create a mouthwatering meal that will have everyone coming back for seconds. Here’s a step-by-step guide to making this delightful dish.

Ingredients:

3 to 4 pounds of beef chuck roast
2 tablespoons olive oil
1 teaspoon salt
1 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon dried thyme
1 teaspoon dried rosemary
1 cup beef broth
1 tablespoon Worcestershire sauce
4 large carrots, peeled and cut into 2-inch pieces
4 medium potatoes, peeled and cut into quarters
1 large onion, quartered
2 cloves garlic, minced
1 cup frozen peas (optional)
Fresh parsley, chopped (for garnish)

Directions:

Prepare the Beef:
Start by patting the beef chuck roast dry with paper towels. This helps the spices stick and promotes better browning.
Mix the Spices:
In a small bowl, mix together the salt, black pepper, garlic powder, onion powder, thyme, and rosemary. This will create a flavorful rub for your roast.
Season the Roast:
Rub the spice mixture all over the beef roast, ensuring it is evenly coated.
Sear the Roast:
In a large skillet, heat the olive oil over medium-high heat. Once hot, add the seasoned roast to the skillet. Sear the roast for about 4-5 minutes on each side until it develops a rich brown crust. This step adds depth to the flavor.
Set Aside the Beef:
Once seared, remove the roast from the skillet and set it aside on a plate to rest while you prepare the vegetables.
Prepare the Vegetables:
Start by peeling and cutting the carrots into 2-inch pieces. Next, peel the potatoes and cut them into quarters. Quarter the onion and set it aside. Finally, mince the garlic cloves for later use.
Layer in the Slow Cooker:
In the bottom of the slow cooker, place the cut carrots, potatoes, and onion. Spread them out evenly. Sprinkle the minced garlic over the vegetables.
Add the Roast:
Place the seared beef roast on top of the vegetables in the slow cooker.
Add Liquid:
In a separate bowl, combine the beef broth and Worcestershire sauce. Pour this mixture over the roast and vegetables. At this point, if desired, you can add a few sprigs of fresh thyme or rosemary on top for added flavor.
Cook:
Cover the slow cooker with its lid and set it to cook on low for 8-10 hours or on high for 4-6 hours. About halfway through the cooking time, check the roast. If you have time, flipping the roast can ensure even cooking.
Check the Temperature:
When the cooking time is up, check the internal temperature of the roast. It should reach at least 145°F (63°C) for medium-rare, but for a more tender result, aim for 190°F (88°C) or higher.
Rest the Roast:
Once the roast is cooked to your desired doneness, carefully remove it from the slow cooker and place it on a cutting board. Let it rest for about 10-15 minutes before slicing.
Final Touches:
While the roast is resting, you can check the vegetables in the slow cooker. If you want to thicken the broth, you can use a cornstarch slurry. If you’re adding frozen peas, stir them in during the last 5 minutes of cooking to heat through.
Serve and Enjoy:
Slice the roast and serve it with the vegetables and broth from the slow cooker. Garnish with fresh parsley for a touch of color and flavor.
