Easy garlic pepper beef is so much better than take out. The beef and peppers are cooked in a savory, rich garlic pepper sauce inspired by Chinese cuisine. Make this quick dinner in 30 minutes or less.
Heat 1 tablespoon vegetable oil over medium heat in a skillet. Once heated add onion, pepper, garlic, and ginger. Season with a pinch of salt and pepper. Cook until the onion begins to turn translucent.
While the veggies are cooking, stir all the ingredients for the sauce into a small bowl. Whisk until well combined and set aside.
After the veggies have cooked add the stir fry beef and top with a pinch of salt and pepper. Cook until the stir fry beef has browned on all sides.
Once done, give the sauce a quick stir to redistribute the corn starch and pour into the pan. Bring to a simmer and cook until reduced by half or about 3-5 minutes. The sauce will be thickened by this point. Serve immediately.
