Beef stir fry is an easy to make weeknight dinner made with strips of tender beef, plenty of colorful veggies, and a delicious homemade stir fry sauce.
Whisk together all of the ingredients for the stir fry sauce in a measuring glass or bowl. Set aside.
Heat a 12" skillet over high heat. Add a tablespoon of oil to the skillet, then add in the bell pepper, green onions, carrots, and sugar snap peas. Cook for 3-4 minutes or until crisp tender. Remove the vegetables from the skillet and onto a plate.
Add the remaining oil to the skillet along with the beef. Season with salt and pepper then sear the beef for 1-2 minutes before flipping it over. Cook for another minute.
Add the vegetables back into the skillet and pour in the stir fry sauce. Stir everything together until it's coated in the sauce. Turn the heat down to medium and simmer until the sauce thickens. Taste for seasoning, then remove from the heat.
Garnish with sesame seeds and chopped cilantro. Serve over rice or noodles.
