Discover the ultimate solution for weeknight dinners with our Quick and Easy Beef & Vegetable Stir Fry recipe. Packed with tender flank steak, vibrant vegetables, and a mouthwatering sauce, this Asian-inspired dish is a delightful balance of flavors and textures.
Start by slicing your flank steak into 1'" slices. Make sure to slice against the grain.
Add all your marinade ingredients to the flank steak and let marinade for 10-15 minutes.
Prepare Veggies
Wash your red pepper and broccolini and slice your red peppers into 1" strips.
Chop your broccolini leaving some of the stems for your stir fry.
Stir Fry
Combine all your sauce ingredients and set aside.
Add your oil to the pan on medium high heat. Let the oil heat up for 3-4 minutes. Add in your beef in two batches to not overcrowd the pan. Flip after 2-3 minutes or once browned. Flip and cook for an additional 2-3 minutes. It's ok if there is a little pink because it will finish cooking in the sauce.
Remove the beef and set aside. Add in your garlic and ginger and sauté for 30 seconds.
Add in your veggies and sauté for 4 minutes. Add in your beef, stir fry sauce, and cornstarch slurry.
Turn your heat down to medium and let it simmer for 3-4 minutes or until the sauce has thickened.
Top with sesame seeds and serve!
