4 cloves garlic, chopped
1/2 teaspoon red pepper flakes
1 cup beef broth
1/2 cup balsamic vinegar

How to Prepare Slow Cooker Balsamic Glazed Roast Beef

Follow these simple steps to bring your dish to life:

Heat the oil in a large pan over medium-high heat. Once hot, add the beef and brown on all sides, about 20 minutes, then set it aside.
In the same pan, add the onions and cook until tender, about 2-3 minutes. Next, stir in the garlic and red pepper flakes, cooking until fragrant, about a minute.
Now, place the beef, cooked onions, beef broth, balsamic vinegar, soy sauce, brown sugar, Worcestershire sauce, and any optional carrots and potatoes into your slow cooker. Cover it and cook on low for 8-10 hours or on high for 3-5 hours.
When done, carefully remove the carrots, potatoes, and beef. Slice or shred the beef to your preference.
Skim any fat from the cooking juices, transfer it to a saucepan, and bring to a simmer. Add the mixture of cornstarch and water, cooking until the glaze has thickened a bit.

Alternatively, if you’re short on time, you can skip browning the beef and simply place everything right into the slow cooker!

Preparation in Advance

Many things can be prepared in advance to make the cooking process smoother. Chop the onions and garlic the night before, and store them in airtight containers in the fridge. You can also pre-measure the ingredients like soy sauce and balsamic vinegar. Just combine everything in the slow cooker in the morning and let it do the work.

Storing and Reheating

To enjoy leftovers, store any uneaten roast beef in an airtight container in the fridge for up to 3 days. For longer storage, freeze it for up to 3 months. When reheating, gently heat in a skillet over low heat or in the microwave until warmed through—the meat should be maintained at a tender texture. One crisp freshness cue is to check that the meat smells fragrant and is not discolored.
