How to Make Chinese Beef and Onion Stir Fry
-
Prepare the crockpot: Lightly grease the ceramic insert of a 5–6-quart oval electric slow cooker with a little vegetable oil, ensuring it’s ready for cooking.
-
Prepare the beef: Slice the beef chuck roast into thin strips, about ¼–½ inch thick, cutting against the grain. Pat the beef dry with paper towels and season it with freshly ground black pepper.
-
Brown the beef: Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat. Sear the beef strips in batches for 1–2 minutes per side until they are lightly browned and fragrant.
-
Prepare the sauce: In a bowl, whisk together the low-sodium soy sauce, beef broth, oyster sauce, brown sugar, rice vinegar, and sesame oil. If you’re using dark soy sauce, add it in for a deeper color.
-
Layer the crockpot: Place half of the onion wedges at the bottom of the slow cooker. Add the browned beef strips, followed by the minced garlic and grated ginger. Pour the prepared sauce evenly over everything.
-
Slow-cook: Cover the crockpot and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the beef becomes fork-tender and flavorful.
-
Add the remaining onions: About 45 minutes before cooking ends on LOW, or 25–30 minutes on HIGH, gently stir in the remaining sliced onions and then cover again.
-
Thicken the sauce: During the last 15–20 minutes, mix 2 tablespoons cornstarch with 2 tablespoons cold water until smooth, then stir this slurry into the crockpot to thicken the sauce.
-
Check for doneness: The beef should be incredibly tender and easy to cut with a fork. If it isn’t, give it a little longer, checking periodically.
-
Finish and serve: Gently toss the beef and onions to coat them in the thickened sauce. Sprinkle with sliced green onions and toasted sesame seeds, if using. Serve hot over steamed jasmine rice or noodles.
Optional: Drizzle with additional sesame oil before serving for an extra burst of flavor!
