Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a skillet over medium heat or in the microwave until warmed through. This recipe also works great for meal prep since the flavors continue to develop as it sits.

Easy Variations & Add-Ins

For extra spice: Add more red pepper flakes, sriracha, or chili garlic sauce to the stir fry sauce.
Add more greens: Toss in fresh spinach during the last 1–2 minutes of cooking until wilted.
Swap the protein: Chicken, shrimp, or ground beef also work well in this recipe.
Make it lower carb: Serve over cauliflower rice instead of regular rice.

Recipe Notes

Thinly slicing the beef helps it cook quickly and stay tender. For the best results, prep all of your vegetables and sauce before cooking since stir fry comes together fast once the heat is on.
