It was born from a craving for Chinese takeout that led to exploration in the kitchen. With just a few smart swaps for traditional ingredients, it keeps the vibrant, tangy appeal of the original dish—minus the sugary carbo-load.
The marinade is the star of this stir-fry show. It marries the deep umami of coconut aminos or soy sauce with the earthy zest of Dijon mustard, the intense pungency of fresh ginger, the bright citrus notes of orange extract, and a hint of sweetness from brown sugar substitute. Those layered flavors soak deeply into the beef as it marinates. Then a quick stir-fry on the stovetop sears in the beef’s tenderness while bringing out the sweet, earthy qualities of red bell pepper and green onions. Making a sauce from reserved marinade ensures that every bite delivers big, bold, Asian-inspired deliciousness!

Tips for choosing meat for this recipe
Selecting the right cut of beef makes all the difference in a successful stir-fry. Flank steak, sirloin, skirt steak, rump steak, and even chuck steak are all excellent choices. They balance tenderness and flavor when sliced and cooked quickly over high heat. Flank steak is especially popular—a quick marinade like the one in this recipe enhances its rich taste, and its grain structure means it becomes exceptionally tender when sliced thinly across the grain. Sirloin and skirt steak offer great beefy flavor and cook up juicy, while rump and chuck can work well if you take care to slice thinly and cook briefly to avoid toughness.
Cutting the beef properly is just as important as the cut you choose. Always slice the meat against the grain into strips no thicker than one-eighth to one-quarter inch. This technique shortens the muscle fibers and ensures each bite is tender and easy to chew. Many grocery stores offer packages of pre-sliced “stir-fry beef” for convenience. They’re tempting as a time-saver, but the thickness or cut can vary, leading to uneven results. Cutting your own from a whole steak gives you more control over thickness, shape, and tenderness, guaranteeing your stir-fry turns out perfect every time.

How do I store leftovers?
Let your stir-fry cool completely before storing it, but don’t leave it at room temp longer than 2 hours. Store leftovers in an airtight container in the fridge for up to 4 days. You can also freeze this dish for up to 3 months in a freezer-safe container or resealable bag with as much air removed as possible. Thaw overnight in the fridge. Reheat on the stovetop or in the microwave, stirring occasionally, until piping hot throughout, adding a splash of broth or water if needed.

- 1/2 teaspoon orange extract
- 2 pounds stir-fry beef
- 2 tablespoons avocado oil
- 1 large red bell pepper chopped
- 1 green onion thinly sliced, plus more for garnish
- 1/2 cup water
- 1/2 teaspoon xanthan gum
Instructions
- In a large measuring cup, whisk together the coconut aminos (or soy sauce), mustard, brown sugar substitute, minced ginger, and orange extract.
- Place the beef in a shallow bowl or resealable bag. Pour in half the marinade, turning the beef pieces to coat evenly. Cover or seal and refrigerate for at least 3 hours. Reserve the remaining marinade for the sauce.
- Remove beef from the marinade and pat dry with paper towels to remove excess liquid. Discard used marinade.
- Heat oil in a large skillet over medium-high. Add beef in a single layer, working in batches if necessary. Stir-fry 3-4 minutes per batch, or until browned and cooked through. Set cooked beef aside.
- Add the bell pepper and green onion to the hot skillet, reserving some green onions for garnish. Stir-fry 2-3 minutes, until peppers are tender-crisp. Remove to the plate with the beef.
- In a small saucepan, combine the reserved marinade and water. Bring to a low boil. Sprinkle in the xanthan gum. Cook while whisking continuously for about 1 minute until the sauce thickens.
- Return beef and vegetables to the skillet. Pour sauce over and toss to coat evenly.
- Serve hot, garnished with sliced green onions if desired.
