How to Make Crockpot Pepper Steak
- Start by slicing sirloin steak into thin strips. Slice against the grain for tender, easy-to-chew strips of beef.
- Then season with salt and pepper, and searing them in a skillet.
- Transfer the beef to your slow cooker, then deglaze the skillet with beef bouillon for extra flavor and pour it over the meat.
- Add in bell peppers, onion, and diced tomatoes, then mix a simple sauce of soy sauce, garlic powder, vinegar, and cornstarch to thicken.
- Cook on low for 6–8 hours or high for 3–4 hours until the beef is tender.
- Leftovers reheat well and can even be frozen for up to three months, making this a great meal prep option.
Make it a meal: Serve over rice, mashed potatoes, or egg noodles to soak up the flavorful sauce.
Cook on low for 6–8 hours or high for 3–4 hours until the beef is tender and the peppers are soft but not mushy.
Sirloin steak is ideal, but you can also use flank steak, chuck steak, or round steak. Just be sure to slice against the grain for tenderness.
Try swapping soy sauce with teriyaki for a sweeter flavor, adding mushrooms for heartiness, or stirring in crushed red pepper for a little heat.
Yes! Store cooled leftovers in an airtight container or freezer bag for up to 3 months.
Warm in the microwave in 1-minute intervals, or heat gently on the stovetop with a splash of broth or water to keep it saucy.

This sounds delicious and I’m glad you talked about steak cuts. I never know what to get and flank steak is my usual go-to (but I only buy it on sale).
It can be really confusing!! Glad I could help!
I disagree with the chuck steaks comment. I always use chuck steaks for slow cooker pepper steak and they cook up more flavorful and tender than round imo because they have some fat. That being said , sirloin tip steak thin sliced was on sale so I will try using that. It’s a round cut so I’ll see how it turns out.
I bought medium round sirloin steaks do I cut them in slices before I brown them or brown them whole and put in slow cooker then after it’s done cut them up?? Ty!
I would brown them after slicing, I am not sure it will be so easy to cut if you brown it whole.
The recipe says petite diced tomatoes, but instructions says stewed tomatoes. Which one is correct?
hello! The post was updated – it’s diced.
How much hot water to the beef bouillon? For sirloin n pepper recipe.
it is 1/4 cup
