Extra vegetables add fiber and nutrients. The sauce has 50% less sugar and sodium than typical versions. It’s proof that healthy eating doesn’t mean boring food.

Equipment Needed

Large skillet or wok
Medium bowl
Small bowl
Measuring cups and spoons
Tongs or a spatula
Sharp knife and cutting board

Ingredients You’ll Need

For the Beef:

1 pound flank steak or sirloin, thinly sliced
2 tablespoons cornstarch
1 tablespoon avocado oil or olive oil
3 cloves garlic, minced
1 tablespoon fresh ginger, minced
4 green onions, cut into 2-inch pieces
1 red bell pepper, sliced (optional)
1 cup broccoli florets (optional)

For the Sauce:

3 tablespoons reduced-sodium soy sauce
2 tablespoons coconut aminos
2 tablespoons honey
1 tablespoon rice vinegar
1 teaspoon sesame oil
½ teaspoon red pepper flakes
¼ cup water
1 teaspoon cornstarch

For Serving:

Cauliflower rice or brown rice
Sesame seeds
Extra sliced green onions

Step-by-Step Instructions

Slice the Beef: Place the beef in the freezer for 15 minutes to firm up (makes slicing easier). Slice against the grain into thin strips, about ¼ inch thick.

Slicing against the grain ensures tender beef that’s easy to chew.

Coat the Beef: Place beef strips in a medium bowl. Sprinkle with 2 tablespoons of cornstarch and toss until evenly coated.

This creates a light coating that helps thicken the sauce without deep-frying.

Make the Sauce: In a small bowl, whisk together soy sauce, coconut aminos, honey, rice vinegar, sesame oil, red pepper flakes, water, and 1 teaspoon cornstarch.

Set aside. The sauce comes together in seconds.

Heat the Pan: Heat 1 tablespoon oil in a large skillet or wok over high heat until shimmering and almost smoking.

High heat is essential for proper searing and preventing steaming.

Sear the Beef: Add beef in a single layer (work in batches if needed to avoid crowding). Let cook undisturbed for 1-2 minutes until browned on the bottom.

Flip and cook another 1-2 minutes until browned but still slightly pink in the center. Remove to a plate.

Cook Aromatics: Reduce heat to medium. Add garlic and ginger to the same pan. Cook 30 seconds, stirring constantly, until fragrant.

Don’t let them burn—they should just become aromatic.

Add Vegetables: If using bell pepper and broccoli, add them now. Stir-fry 2-3 minutes until crisp-tender.

Extra vegetables increase volume and nutrition without adding many calories.

Add Sauce: Give the sauce a quick stir and pour it into the pan. Bring to a simmer, stirring constantly.

The sauce will thicken within 1-2 minutes as the cornstarch activates.

Combine: Return beef to the pan along with green onions. Toss everything together for 1-2 minutes until the beef is coated and heated through.

The sauce should be glossy and cling to the beef.

Serve: Serve immediately over cauliflower rice or brown rice. Garnish with sesame seeds and extra green onions.

This dish is best enjoyed fresh and hot.

Ingredient Substitutions

Tips for Success

Slice Against Grain: Creates tender beef. Look for lines in the meat and cut perpendicular.

High Heat Essential: Creates a sear without overcooking. Don’t be afraid of high heat.

Don’t Overcrowd: Cook beef in batches if needed. Crowding causes steaming instead of searing.

Partially Freeze Beef: Makes slicing thin strips much easier and more uniform.

Prep Everything First: Stir-frying moves fast. Have everything ready before starting.

Add Vegetables: Increases nutrition and volume without many calories.

Taste and Adjust: Add more honey for sweetness or soy sauce for saltiness.

Serving Suggestions

With Cauliflower Rice: Keeps it low-carb and adds vegetables. Reduces calories compared to regular rice.

Brown Rice Bowl: Whole grain provides fiber and keeps you full longer.

Lettuce Wraps: Serve in crisp lettuce leaves for a fun, low-carb option.

Meal Prep: Portion into containers with rice and vegetables for grab-and-go lunches.

Side Dishes: Pair with steamed edamame, cucumber salad, or Asian slaw.

Storage and Reheating

Refrigerator: Store in an airtight container for up to 4 days.

Freezer: Freeze up to 2 months. Thaw overnight in the refrigerator.

Reheating: Best in a skillet over medium heat with a splash of water. The microwave works, but it may overcook the beef.

Meal Prep: Store beef separately from rice for the best texture.

Add Fresh: Top with fresh green onions and sesame seeds when reheating.

Variations to Try

Extra Vegetables: Add snap peas, mushrooms, carrots, or baby corn.

Spicy Version: Increase red pepper flakes or add sriracha.

Orange Beef: Add 2 tablespoons orange juice and 1 teaspoon orange zest.

Teriyaki Style: Use honey and add 1 tablespoon mirin.

Protein Swap: Use chicken, shrimp, or tofu instead of beef.

Whole30: Use coconut aminos only, replace honey with date paste.

Common Mistakes to Avoid

Overcooking Beef: Cook just until browned. It continues cooking in the sauce.

Low Heat: Creates gray, steamed beef instead of caramelized sear.

Too Much Sauce: Should coat beef, not drown it. Start with less.

Skipping Cornstarch: Coating beef helps create a silky sauce texture.

Not Slicing Against Grain: Creates tough, chewy beef.

Adding Vegetables Too Late: They need time to cook through.

Using Fatty Cuts: Ribeye or chuck has too much fat for a healthy version.
