Why You’ll Love This Crockpot Pepper Steak
This recipe is easy, filling, and made with simple ingredients you can find at almost any grocery store. The slow cooker does most of the work, which makes it a great choice when you want a hot dinner waiting for you at the end of the day.
It is also a beautiful dish for the table. The tender beef, red and green bell peppers, and glossy sauce make it look colorful and appetizing. Even though it is simple to prepare, it tastes like comfort food with a little extra flavor.
Another reason this recipe works so well is that it is flexible. You can use sirloin steak, round steak, flank steak, or even stew meat if that is what you have. You can make the sauce sweeter, spicier, thicker, or more garlicky depending on your family’s taste.
For best food safety, USDA guidance recommends thawing meat before adding it to a slow cooker and keeping the lid in place during cooking.
Ingredients You’ll Need
This crockpot pepper steak recipe uses simple, everyday ingredients, but each one plays an important role in building that rich, savory flavor. The beef becomes tender as it slow cooks, while the peppers, onions, garlic, and sauce come together into a cozy dinner that tastes like it took much more effort than it actually did.
Beef
Use 2 pounds of beef sirloin, round steak, or flank steak, sliced into thin strips. Sirloin gives you a tender, flavorful bite, while round steak is a great budget-friendly option that works beautifully in the slow cooker. If using flank steak, slice it against the grain so it stays tender.
Bell Peppers
You’ll need green and red bell peppers, sliced into strips. Green bell peppers add a classic pepper steak flavor, while red bell peppers bring a little natural sweetness and beautiful color. You can also add yellow or orange bell peppers if you want the dish to look extra bright and colorful.
Onion
A large sliced onion adds sweetness and depth as it cooks down into the sauce. Yellow onion works best, but white onion can also be used.
Garlic
Fresh minced garlic gives the sauce a warm, savory flavor. I recommend using fresh garlic if possible, but garlic powder can work in a pinch.
Beef Broth
Beef broth creates the base of the sauce and helps keep the meat moist while it cooks. Use low-sodium beef broth if you want more control over the salt level.
Soy Sauce
Low-sodium soy sauce adds that rich, salty, umami flavor that makes pepper steak so delicious. Low-sodium is best because the sauce will concentrate slightly as it cooks.
Worcestershire Sauce
A splash of Worcestershire sauce adds depth, tanginess, and a little extra savory flavor to the sauce.
Brown Sugar
A small amount of brown sugar balances the salty and savory ingredients. It does not make the dish overly sweet — it simply rounds out the sauce.
Diced Tomatoes
Diced tomatoes, with their juices, add body and a slight tang to the sauce. They also help keep the beef tender during slow cooking.
Seasonings
A simple blend of ground ginger, black pepper, and optional red pepper flakes gives the dish warmth and just a little kick. If your family likes mild dinners, you can skip the red pepper flakes.
Cornstarch Slurry
A mixture of cornstarch and cold water is stirred in near the end of cooking to thicken the sauce. This gives the pepper steak that glossy, spoonable sauce that tastes perfect over rice or noodles.
For Serving
Serve your crockpot pepper steak over white rice, brown rice, egg noodles, mashed potatoes, or cauliflower rice. The sauce is rich and flavorful, so choose something that can soak it all up.
Best Beef for Crockpot Pepper Steak
The best beef for pepper steak is a cut that becomes tender with slow cooking. Sirloin steak is a great option because it has good flavor and cooks nicely when sliced thin. Round steak is budget-friendly and works well in the slow cooker because the long cooking time helps break it down. Flank steak is also delicious, but it should be sliced against the grain so it stays tender.
Try to cut the beef into even strips. This helps the meat cook at the same rate and makes the finished dish easier to serve over rice or noodles.
How to Make Crockpot Pepper Steak
Start by slicing the beef into thin strips. If you have time, brown the beef in a skillet with a little olive oil for 2 to 3 minutes per side. This step is optional, but it adds extra flavor to the finished dish.
Place the sliced beef into the bottom of the crockpot. Add the sliced onions, minced garlic, beef broth, soy sauce, Worcestershire sauce, brown sugar, ginger, black pepper, red pepper flakes, and diced tomatoes. Stir gently so the beef is coated in the sauce.
Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the beef is tender. About 45 minutes before serving, add the sliced bell peppers. Adding the peppers near the end helps them stay colorful and slightly firm instead of becoming too soft.
In a small bowl, whisk together the cornstarch and cold water until smooth. Stir this mixture into the crockpot during the last 20 to 30 minutes of cooking. This will thicken the sauce and give it that glossy pepper steak texture.
Serve hot over rice, noodles, or mashed potatoes. Spoon extra sauce over the top and garnish with green onions or parsley if desired.
Tips for the Best Pepper Steak
Do not add the bell peppers too early unless you like them very soft. For the best texture, add them during the final 45 minutes of cooking.
Slice the beef against the grain whenever possible. This helps the meat feel more tender when you bite into it.
Use low-sodium soy sauce if you can. Regular soy sauce can make the dish too salty, especially as the sauce cooks down.
If you want a thicker sauce, add an extra teaspoon of cornstarch mixed with cold water near the end. If the sauce gets too thick, stir in a splash of beef broth.
USDA safety guidance lists 145°F with a 3-minute rest as the safe minimum temperature for beef steaks and roasts, though slow cooker pepper steak is usually cooked longer for tenderness.
What to Serve with Crockpot Pepper Steak
The most classic way to serve pepper steak is over steamed white rice. The rice soaks up the savory sauce and makes the meal extra filling. Brown rice is a great option if you want something heartier.
Egg noodles are also delicious with this recipe, especially if you like a cozy beef-and-noodle style dinner. Mashed potatoes make it feel like a true comfort food meal. For a lighter plate, serve it with cauliflower rice, roasted broccoli, green beans, or a simple side salad.
Storage and Reheating
Store leftover crockpot pepper steak in an airtight container in the refrigerator for up to 3 to 4 days. Reheat it gently on the stovetop or in the microwave until hot. If the sauce thickens too much after chilling, add a small splash of beef broth or water before reheating.
You can also freeze pepper steak for up to 2 months. Let it cool completely, place it in freezer-safe containers, and thaw overnight in the refrigerator before reheating.
Recipe Variations
For a spicier version, add extra red pepper flakes or a spoonful of chili garlic sauce. For a sweeter sauce, add another tablespoon of brown sugar. For more vegetables, add mushrooms, baby corn, carrots, or snap peas near the end of cooking.
You can also make this recipe more Asian-inspired by adding a drizzle of sesame oil before serving. For a more classic American-style pepper steak, keep the sauce simple with beef broth, tomatoes, peppers, onions, and Worcestershire sauce.
