  • Cooked rice optional for serving
  • Sesame seeds optional for serving

Equipment

Method
 

  1. In a medium bowl, toss the thinly sliced beef with cornstarch, salt, and black pepper. Make sure each piece of beef is lightly coated. This coating helps tenderize the beef and create a lovely sauce later on.

  2. Heat the vegetable oil in a large skillet over medium-high heat. Add the coated beef in batches and sear for about 1-2 minutes per side, until browned. This step adds an extra layer of flavor and texture to the beef. Do not overcrowd the pan; cook in batches if necessary. Remove the seared beef from the skillet and set aside.

  3. In the same skillet (no need to wash), add the sliced onion and cook for about 5-7 minutes, until softened and lightly caramelized. Then, add the minced garlic and grated fresh ginger and cook for an additional minute until fragrant. Be careful not to burn the garlic.

  4. Pour in the beef broth, soy sauce, brown sugar, oyster sauce, and rice vinegar. Stir everything together, scraping up any browned bits from the bottom of the skillet. Bring the mixture to a simmer and cook for about 2 minutes, allowing the flavors to meld and the sugar to dissolve.
    1 cup Beef broth, 0.5 cup Soy sauce, 0.25 cup Brown sugar, 2 tablespoons Oyster sauce, 1 tablespoon Rice vinegar
  5. Place the seared beef into the bottom of your slow cooker. Pour the prepared sauce mixture evenly over the beef.

  6. Cover the slow cooker and cook on low for 3-4 hours, or until the beef is fork-tender. The exact cooking time will depend on your slow cooker model and the cut of beef you use.
  7. About 20-30 minutes before serving, stir in the broccoli florets. If you prefer softer broccoli, add it earlier.
    1 pound Broccoli florets
  8. Continue to cook on low with the lid on until the broccoli is tender-crisp and bright green. Avoid overcooking the broccoli, as it can become mushy.
  9. If you desire a thicker sauce, you can remove the beef and broccoli from the slow cooker and whisk together 1-2 tablespoons of cornstarch with 2-3 tablespoons of cold water to create a slurry. Stir this slurry into the remaining sauce in the slow cooker and cook on high for a few minutes until thickened. Then, return the beef and broccoli to the pot.
    1-2 tablespoons Cornstarch, 2-3 tablespoons Cold water
  10. Serve the Mouthwatering Crock Pot Beef and Broccoli hot over your favorite cooked rice. Garnish with sesame seeds and chopped green onions, if desired.
