Dr Pepper Beef Stir-Fry Recipe

Yields: 4 servings
Prep Time: 15 minutes
Cook Time: 15 minutes



  • 1 lb flank steak (or sirloin), thinly sliced against the grain


  • 1/4 cup Dr Pepper
  • 2 tbsp soy sauce
  • 1 tbsp cornstarch
  • 1/2 tsp garlic powder
  • 1/4 tsp ground ginger
  • 1/4 tsp red pepper flakes (optional)


  • 1 tbsp vegetable oil
  • 1/2 red onion, sliced
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced (optional)
  • 1 cup broccoli florets (optional)

Optional Garnishes:

  • Sesame seeds
  • Sliced green onions


Marinade the beef:

  • In a medium bowl, whisk together Dr Pepper, soy sauce, cornstarch, garlic powder, ginger, and red pepper flakes (if using).
  • Add sliced beef to the marinade and toss to coat. Let it marinate in the refrigerator for at least 30 minutes, or up to a few hours for stronger flavor.

Prepare the vegetables:

  • While the beef marinates, slice the onions and bell peppers.
  • Cut broccoli into florets if using.

Cook the beef:

  • Heat a large skillet or wok over high heat. Add half the vegetable oil.
  • Remove beef from marinade (reserve the marinade) and add it to the hot skillet in a single layer. Cook for 1-2 minutes per side, or until browned but not fully cooked through.
  • Remove cooked beef from skillet and set aside.

Cook the vegetables:

  • Add the remaining oil to the skillet. Add sliced onion and bell peppers (and broccoli, if using).
  • Stir-fry for 2-3 minutes, or until slightly softened and starting to brown.

Make the sauce:

  • Give the reserved marinade a quick whisk, then pour it into the skillet with the vegetables.
  • Bring to a simmer and cook for 1-2 minutes, or until the sauce thickens slightly.

Combine and finish:

  • Return the cooked beef to the skillet along with any accumulated juices.
  • Stir-fry for another 1-2 minutes, or until the beef is fully cooked and the sauce coats everything evenly.


  • Serve immediately over hot rice or noodles.
  • Garnish with sesame seeds and sliced green onions, if desired.


  • Don’t overcook the beef: It will become tough. Aim for lightly browned on the outside with a bit of pink in the middle. It will finish cooking when combined with the sauce.
  • Choose your vegetables: Use whatever vegetables your family enjoys. Mushrooms, snow peas, and carrots would all work well.
  • Adjust the spice level: Omit or increase the red pepper flakes for desired heat level.
