Ingredients
- 2 lbs beef sirloin, sliced
Beef sirloin is chosen for its balance of tenderness and flavor, making it ideal for slow cooking. As it simmers in the crock pot, the connective tissues break down, resulting in incredibly tender meat. - 1 medium onion, sliced
Onions add sweetness and depth to the dish, enhancing the overall flavor profile. When caramelized together with the beef, they contribute a rich, savory base. - 2 bell peppers (any color), sliced
Bell peppers provide vibrant color and a crunchy texture that contrasts wonderfully with the tender beef. They also introduce a slightly sweet and earthy flavor. - 3 cloves garlic, minced
Garlic infuses the dish with its distinct, aromatic flavor, enriching the overall taste. Its antioxidant properties also make the meal more healthful. - 1 cup beef broth
Beef broth serves as the liquid base for the dish, providing moisture and a deep, savory flavor. It helps to break down the meat effectively during the cooking process. - 1/4 cup soy sauce
Soy sauce adds saltiness and umami to the dish, heightening the savory notes. It also aids in tenderizing the beef, making it more succulent. - 1 tablespoon Worcestershire sauce
Worcestershire sauce delivers a tangy complexity that ties all the flavors together, adding a subtle sweetness to the dish. - 1 tablespoon cornstarch
Cornstarch is used to thicken the sauce towards the end of cooking. It gives the dish a glossy finish and makes the sauce cling beautifully to the beef and vegetables. - Salt and pepper to taste
Seasoning with salt and pepper is essential to enhance the flavors of the dish. Adjusting these to your taste can balance out the rich flavors from the beef and sauces.
Directions & Preparation
Step 1: Prepare the beef and vegetables.
Start by slicing the beef sirloin into thin strips, ideally against the grain, to ensure tenderness. Next, slice the onion and bell peppers into strips. This step is crucial as it ensures that the beef and vegetables will cook evenly and meld together beautifully in the crock pot.
Step 2: Mix the sauce ingredients in a bowl.
In a mixing bowl, combine the beef broth, soy sauce, and Worcestershire sauce. This mixture will become the flavorful base for your pepper steak, allowing the beef to absorb these rich flavors as it cooks slowly. Take care to whisk them together properly to ensure that the flavors blend well.
Step 3: Layer the ingredients in the crock pot.
Start by placing the sliced beef at the bottom of the crock pot, followed by the onion and bell peppers. Pour the sauce mixture over the top. This layered approach allows the juices to seep down into the meat while protecting the vegetables from overcooking.
Step 4: Cook on low for 6-8 hours or high for 3-4 hours.
Cooking on low for a longer period helps the meat become incredibly tender while allowing the flavors to develop fully. If pressed for time, the high setting can work too, but monitor the dish to prevent overcooking, as shorter times can lead to less tender meat.
Step 5: Thicken the sauce with cornstarch.
About 30 minutes before serving, mix cornstarch with a bit of water to create a slurry, then stir it into the crock pot. This step is important for achieving that thick, velvety sauce that clings well to the beef and veggies, enhancing each bite with flavor.
Step 6: Serve hot, and enjoy your meal.
Once the cooking time is up, give the dish a gentle stir before serving. This final step ensures that all ingredients are well-incorporated, and the sauce evenly coats the beef and vegetables, maximizing flavor. Pairing it with rice or noodles makes for a fulfilling meal.

Enhancing Flavor with Fresh Herbs
Incorporating fresh herbs like parsley or cilantro can elevate the flavor of your crock pot pepper steak. Adding finely chopped herbs just before serving introduces a fresh aroma and a vibrant touch to the dish. The herbs enhance both the visual appeal and flavor profile, offering an herbal brightness that contrasts nicely with the rich beef.
Choosing the Right Cut of Beef
While sirloin is a favorite for pepper steak, experimenting with other cuts can yield delicious results. Cuts like flank steak or chuck roast are flavorful options that also become tender with slow cooking. It’s essential to select meat with good marbling; the fat renders during cooking, contributing to the dish’s richness.
Serving Suggestions That Wow
Pairing your crock pot pepper steak with sides can take your meal to the next level. Serving it over a bed of steamed rice or alongside mashed potatoes allows the savory sauce to soak in. For a lighter option, consider a side of stir-fried vegetables or a fresh salad, bringing balance and variety to your meal.
