Begin by preparing your slow cooker. No need to preheat—just plug it in and set it on low. Slice your onions into thin rings and cut beef into chunks.

Place the sliced onions at the bottom of the slow cooker, followed by the beef chunks on top, spreading them evenly.

Season generously with salt and pepper. Optionally, add your favorite herbs or spices.

Cover the slow cooker and set to low for 6–8 hours or high for 3–4 hours.

Once cooked, check the beef for fork-tenderness. Serve over rice, in a sandwich, or with vegetables.
