Stir-fried beef with flax seeds is a sweet-savory weeknight dinner ready in nine minutes of cooking. Beef strips soak up a marinade of coconut aminos, honey, garlic, and red pepper flakes before hitting the wok with crisp red peppers. Flax seeds stirred in at the end add nutty crunch and a serious nutrition boost.
Pro Tips
- Marinate the beef for at least 30 minutes — overnight is even better. The honey and aminos tenderize the meat and glaze it beautifully in the hot wok.
- Keep the wok genuinely hot and cook the peppers just 2 minutes. Crisp-tender is the target; limp peppers lose all their snap.
- The marinade doubles as the sauce. Let it reduce those final minutes until it thickens and clings to the beef rather than pooling in the pan.
- Add the flax seeds only in the last 2 minutes so they toast lightly without burning.
Frequently Asked Questions
What cut of beef works best for stir-fry?
Pre-cut beef stir-fry strips are the easy choice. Flank or sirloin sliced thinly against the grain work just as well.
Can I use a different seed instead of flax?
Sesame seeds would fit the Asian flavor profile, but flax gives this recipe its distinctive nutty crunch and omega-3 boost.
How many servings does this recipe make?
Four servings, ready in under an hour including the marinade time — a perfect weeknight dinner.
What should I serve alongside this stir-fry?
Cauliflower rice soaks up the honey-aminos sauce perfectly, or serve it over sautéed greens for a lighter plate.
