Skip the takeout and enjoy this slow cooker beef and broccoli made with tender beef and broccoli in a savory homemade sesame soy sauce. Serve over rice or noodles for a comforting, restaurant-style meal the whole family will love.
Add soy sauce, beef broth, brown sugar, rice vinegar, sesame oil, ground ginger, black pepper, red pepper flakes, and garlic in a medium bowl. Whisk until well combined.
Add sliced beef to the Crockpot and cover with sauce. Mix until meat is completely coated.
Cover and cook on low for 5-6 hours on high for 2½-3½ hours.
Forty-five minutes before cooking time is up. Make a slurry with 3 tbsp of cornstarch and ⅓ cup of water. Mix until there are no lumps and add to the Crockpot. Mix until well combined. Add broccoli and finish cooking.
Serve while hot over noodles or rice, and enjoy!
Notes
Whisk the cornstarch slurry well to avoid lumps in the sauce.
Add broccoli towards the end of cooking to avoid overcooking.
Slice beef thinly against the grain for the most tender texture.
