How to Make Crock Pot Pepper Steak
1. Slice the Beef
Trim excess fat from the beef and cut it into thin strips.
If you’re using flank steak, slicing against the grain can help make the finished beef more tender.
Try to keep the pieces relatively similar in size so they cook evenly.
2. Brown the Beef — Optional
Heat a little oil in a skillet over medium-high heat.
Brown the beef strips briefly on both sides.
You don’t need to cook them through because they’ll finish cooking in the slow cooker.
Browning isn’t essential, but it can add another layer of flavor.
If you’re short on time, you can skip this step and add the seasoned beef directly to the slow cooker. Some modern versions use a simple dump-and-go method.
3. Prepare the Sauce
In a bowl, whisk together:
- Beef broth
- Soy sauce
- Worcestershire sauce
- Brown sugar
- Garlic
- Black pepper
- Optional ginger
- Optional red pepper flakes
Mix until the sugar is mostly dissolved.
4. Add Everything to the Crock Pot
Place the beef into the slow cooker.
Add the sliced onion and garlic.
Pour the sauce over the beef and gently stir.
For the best texture, keep the bell pepper pieces relatively thick.
5. Slow Cook
Cover the slow cooker and cook on LOW for approximately 6–8 hours, or until the beef is tender.
You can also cook it on HIGH for approximately 3–4 hours, depending on your slow cooker and the cut of beef.
Avoid repeatedly lifting the lid because it releases heat and can increase the cooking time.
6. Add the Bell Peppers
For softer peppers, add them earlier in the cooking process.
If you prefer peppers that retain more texture and color, add them during the final hour or so. Several slow-cooker versions recommend adding peppers later specifically to prevent them from becoming overly soft.
7. Thicken the Sauce
About 20–30 minutes before serving, mix the cornstarch and cold water in a small bowl.
Whisk until completely smooth.
Pour the slurry into the slow cooker and stir gently.
Turn the slow cooker to HIGH and allow the sauce to cook until it becomes noticeably thicker and glossy.
This final thickening step is commonly used in Crock Pot pepper steak recipes.
How to Serve It
The classic way to serve Crock Pot Pepper Steak is over hot steamed rice.
Spoon the tender beef, peppers, onions, and plenty of sauce over the rice.
You can also serve it with:
- Brown rice
- Egg noodles
- Rice noodles
- Mashed potatoes
- Quinoa
- Cauliflower rice
The savory sauce is especially delicious when it soaks into the rice.
Tips for Tender Pepper Steak
Slice Against the Grain
When using flank steak or another fibrous cut, slicing across the muscle fibers can make the beef easier to chew.
Don’t Cut the Peppers Too Thin
Thicker strips hold their shape better during slow cooking.
Don’t Add Too Much Salt
Soy sauce and beef broth can already contain significant sodium. Taste the finished sauce before adding additional salt.
Don’t Skip the Cornstarch Slurry
If you prefer a thicker, gravy-like sauce, the slurry makes a noticeable difference.
Always mix cornstarch with cold water first to prevent lumps.
Easy Variations
Spicy Pepper Steak
Add extra red pepper flakes, cayenne, or sliced jalapeños.
Extra Vegetable Pepper Steak
Add mushrooms, broccoli, carrots, or snow peas toward the end of cooking.
Sweet and Savory Version
Increase the brown sugar slightly or substitute honey for a softer sweetness.
Garlic-Ginger Pepper Steak
Use extra fresh garlic and grated ginger for a stronger Asian-inspired flavor.
Colorful Bell Peppers
Use a combination of green, red, yellow, and orange peppers. This adds beautiful color as well as slightly different levels of sweetness.
Can You Make It Ahead?
Yes. Pepper steak is a convenient make-ahead meal.
Once cooked, allow it to cool appropriately and refrigerate leftovers promptly in an airtight container.
When reheating, warm the beef and sauce thoroughly. If the sauce becomes too thick after refrigeration, add a small splash of beef broth or water while reheating.
Can You Freeze Pepper Steak?
Yes, the cooked beef and sauce can generally be frozen in a freezer-safe container.
For the best quality, freeze it separately from the rice.
Thaw safely in the refrigerator and reheat thoroughly before serving.
