These tasty, melt-in-your-mouth-tender beef strips are sautéed in a creamy 5-ingredient peanut sauce!
1 pound Flank or Skirt Steak thinly sliced across the grain
2-3 teaspoons oil
1/2 cup creamy peanut butter
2 teaspoons soy sauce
1 tablespoon brown sugar
2 teaspoons Sriracha hot sauce
1/4 cup peanuts, chopped optional
3-4 tablespoons water, to thin if needed
Whisk together all sauce ingredients excluding peanuts. Add water 1 tablespoon at a time until sauce is a smooth, pourable consistency.
Add oil to large pan or skillet and heat over medium high heat until hot. Add beef strips and cook 8-10 minutes, stirring throughout to ensure even cooking.
When beef has browned around edges and cooked to desired doneness. Add 1/2 of the sauce to the pan. Stir and cook 1-2 minutes longer. Top with remaining sauce and chopped peanuts. Garnish with sliced green onions or cilantro if desired and serve.
