Thai basil is the real star here ~ sweet, peppery, and slightly aniseed ~ it transforms simple beef and vegetables into something that tastes restaurant-quality. You can make this mild or spicy, use whatever fresh vegetables you have on hand, and still end up with a vibrant, nourishing dinner that the whole family will love. Serve it over brown rice, cauliflower rice, or quinoa, and you’ve got a wholesome meal that’s as quick as it is satisfying.

Tips For The Best Thai Basil Beef

Slice the beef very thinly for quick, tender cooking
Cook in a hot wok for authentic stir-fry flavour
Use Thai basil (or Holy basil) ~ sweet basil won’t give the same taste
Boost chilli for heat if desired
Choose lean rump or flank teak for best results
Don’t overcook the vegetables ~ keep them crisp and vibrant
Stir the basil through at the end for maximum aroma
