Savory Slow Cooker Pepper Steak Deluxe is a game-changer for busy weeknights or when you crave something hearty without the fuss. This recipe combines tender beef, vibrant bell peppers, and a rich, flavorful sauce that all cook together seamlessly in your slow cooker.
Flank steak is ideal here because it becomes tender and flavorful over the long, slow cooking process. The all-purpose flour helps to give the steak a slight crust when you brown it, which adds depth to the dish. Salt and black pepper season the meat right from the start.
Olive oil is used for browning, which is a crucial step for flavor. Onion and bell peppers (green and red) bring sweetness and freshness to the dish, while garlic offers a sharp, aromatic punch. The soy sauce and beef broth form the base of a savory sauce, enhanced by brown sugar for a hint of sweetness, and Worcestershire sauce for umami depth.
Ground ginger adds a subtle warmth. The cornstarch mixed with water thickens the sauce to a perfect glaze. Finally, serve it all over jasmine rice, which is fragrant and absorbs the sauce beautifully.
This dish pairs wonderfully with a simple side salad or steamed green beans for some extra greens. You can also sprinkle some fresh chopped cilantro or parsley on top for a burst of color and flavor.
Start by mixing the flour, salt, and black pepper in a bowl. Coat your flank steak strips in this mixture, which will help form a nice crust once browned. Heat up some olive oil in a skillet over medium-high heat. You'll want to brown the steak in batches — don't overcrowd the pan, or you'll steam the meat instead of browning it. Once browned, move the steak to your slow cooker.
In the same skillet, toss in the sliced onions and cook them until they turn translucent, which should take about 5 minutes. Add the minced garlic and sauté for another minute, just until fragrant. Transfer these to the slow cooker as well, along with the sliced green and red bell peppers.
Now, in a bowl, whisk together the soy sauce, beef broth, brown sugar, Worcestershire sauce, and ground ginger. Pour this flavorful mixture over the beef and vegetables in the slow cooker.
Cover your slow cooker and set it to low for 6-7 hours or high for 3-4 hours. The beef should be melt-in-your-mouth tender by the end. About 30 minutes before serving, mix cornstarch and water in a small bowl until smooth, then stir it into the slow cooker to thicken the sauce.
When everything is ready, serve it hot over a bed of cooked jasmine rice. Enjoy the rich, savory flavors and tender beef with each bite!
