How do you cook pepper steak in a Crock Pot?

When I make pepper steak in my Crock Pot, I like to layer the beef first and then top it with bell peppers and onions. I whisk together a simple sauce of soy sauce, beef broth, garlic, ginger, a touch of sugar, and cornstarch, and pour it over the ingredients. Cooking it on low for 6-7 hours—or high for 3-4—lets the beef become tender while the vegetables soak up the sauce. The aroma as it cooks is incredible; it’s like the whole kitchen is giving you a warm invitation to dinner.

What is the best cut of steak to use for pepper steak?

I always reach for sirloin when I make this recipe. It’s tender but still has enough structure to hold up during slow cooking. Flank or ribeye can work too, but sirloin hits the sweet spot of tenderness and flavor without needing complicated prep. Slicing it thin ensures every piece absorbs the sauce beautifully.

Can you slow cook steak in a slow cooker?

Absolutely! Slow cooking steak is one of my favorite ways to get tender, flavorful meat. The key is to use cuts that have some natural marbling or a bit of connective tissue, and cook them low and slow. Over several hours, the meat softens without drying out, and it literally melts in your mouth—something you just can’t achieve with quick pan-searing.

What sauce is on pepper steak?

The sauce I use is simple but packed with flavor: soy sauce, beef broth, garlic, ginger, a hint of sugar, and cornstarch to thicken it. It’s savory, slightly sweet, and perfectly coats the beef and vegetables. When it simmers in the Crock Pot, the flavors deepen and blend, giving you that rich, glossy sauce that clings to every bite of steak and pepper.
