Quick and flavorful Thai Basil Beef Stir-Fry ready in under 20 minutes! Tender beef, garlic, chili, and Thai basil create a bold, aromatic dish you can easily adjust for spice.
Smash garlic and chili in a mortar and pestle until they are roughly chopped. Or use a knife to finely chop them; set aside.
Mix stir-fry sauce ingredients in a small bowl and set aside.
Pound thin beef slices with a meat hammer to tenderize, and slice into desired sizes.
Heat 1 tablespoon of oil in a wok or skillet over high heat. Stir-fry smashed chili and garlic for 30 seconds. Add beef and stir-fry for 2 minutes until browned. Transfer beef to a plate and set aside.
Heat remaining 1 tablespoon oil, add onion, and stir fry for 30 seconds. Add long beans and continue to stir fry until beans are tender and crisp, about 1-2 minutes.
Return beef and the sauce mixture and stir to coat. Add Thai basil leaves and stir to heat through. Serve hot with rice. Note: Often a fried egg is added on top, but that’s optional.
Notes
If you want this less spicy, use finger-long red chilies instead of Thai bird's eye chilies
