How to Make Pepper Steak in a Crock Pot
Step 1: Layer the Beef in Your Slow Cooker
Start this Pepper Steak in a Crock Pot adventure by arranging the thinly sliced beef sirloin or flank steak right at the bottom of your slow cooker. This ensures that every bite will soak up maximum flavor and turn silky-tender as it cooks, giving you juicy, melt-in-your-mouth steak with every serving.
Step 2: Whisk Up the Flavorful Sauce
In a small mixing bowl, whisk together the cornstarch, low-sodium soy sauce, beef broth, brown sugar, sesame oil, minced garlic, ground ginger, and black pepper. Aim for a smooth, lump-free sauce (it should smell incredible even before it cooks!). This mixture creates the bold, glossy base that coats the meat and veggies from the very start.
Step 3: Pour the Sauce and Coat the Beef
Pour your prepared sauce evenly over the beef in the Crock Pot, making sure every piece gets some love. Give everything a gentle stir so the beef slices are coated in that savory, sweet, and slightly garlicky goodness. Don’t worry if it looks a little thin right now—the magic thickening happens as it simmers slowly.
Step 4: Add the Peppers and Onion
Layer the sliced red bell pepper, green bell pepper, and onion on top. Placing the veggies at this stage ensures they cook just enough to become tender, but still keep their vibrant color and a little bit of crunch—perfection for classic Pepper Steak in a Crock Pot.
Step 5: Slow Cook to Tender Perfection
Pop the lid on and set your slow cooker to low for 5 to 6 hours, or on high for about 2.5 to 3 hours. The beef will become incredibly tender, and the sauce will thicken and cling to every piece. If you’d like a thicker sauce, you can crack the lid during the last 30 minutes or stir in a quick cornstarch slurry at the end. Stir before serving so everything gets tossed in that flavorful sauce.
