Ingredients

• 2 pounds sirloin (cut into 2-inch by ½-inch strips)
• 2 teaspoons garlic powder
• ½ teaspoon kosher salt
• ½ teaspoon ground black pepper
• 1 tablespoon neutral oil (canola, grapeseed, or similar)
• 1 large yellow onion (sliced)
• 2 green bell peppers (cored and cut into ½-inch strips)
• 2 red (or yellow/orange bell peppers, cored and cut into ½-inch strips)
• ¼ cup plus 2 tablespoons water (divided)
• 1 15-ounce can fire-roasted diced tomatoes (with juices)
• ¼ cup low sodium soy sauce (plus additional to taste)
• 2 tablespoons Worcestershire sauce
• 2 tablespoons honey
• 1 tablespoon minced fresh ginger
• ¼ teaspoon red pepper flakes (plus additional to taste)
• 5 tablespoons cornstarch (divided)
• Prepared brown rice (quinoa, or cauliflower rice) for serving

How to make Crock Pot Pepper Steak

Step 1: Start by seasoning your beef. In a medium bowl, toss the sirloin strips with the garlic powder, kosher salt, and black pepper until they are evenly coated.

Step 2: Heat the neutral oil in a large skillet over medium-high heat. Add the seasoned beef strips and sear them on all sides until they develop a nice brown crust, which should take about 5 minutes. Don’t worry about cooking them through. This searing step is crucial for developing a deep, rich flavor. Once browned, transfer the beef and any pan juices to your 6-quart slow cooker.

Step 3: In the same skillet, add the sliced onion. Turn the heat up to high and pour in ¼ cup of water. Use a wooden spoon or spatula to scrape up all those delicious browned bits from the bottom of the pan. Sauté the onions for about 3 minutes until they soften and start to brown, then add them to the slow cooker with the beef.

Step 4: Add the sliced green and red bell peppers to the slow cooker, along with the entire can of fire-roasted diced tomatoes, including the juices.

Step 5: Now, let’s make the magic sauce. In a small bowl, whisk together the low sodium soy sauce, Worcestershire sauce, honey, minced ginger, red pepper flakes, and 3 tablespoons of the cornstarch. Whisk until the cornstarch is fully dissolved and the sauce is smooth.

Step 6: Pour this beautiful sauce mixture over all the ingredients in the slow cooker. Give it a gentle stir to combine everything. Cover the slow cooker and set it to cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours. The LOW setting will yield the most tender beef.

Step 7: About 10 minutes before you’re ready to serve, it’s time to thicken the gravy. In a small bowl, create a slurry by mixing the remaining 2 tablespoons of cornstarch with 2 tablespoons of cold water until smooth. Stir this slurry into the slow cooker.

Step 8: Turn the slow cooker to the HIGH setting, leave it uncovered, and let it cook for about 10 more minutes. This will allow the sauce to thicken into a rich, velvety gravy. Give it a final taste and adjust with more salt, soy sauce, or red pepper flakes if needed. Your kitchen will smell absolutely incredible!

How to serve Crock Pot Pepper Steak

The classic way to serve this Crock Pot Pepper Steak is spooned generously over a bed of fluffy brown rice. The rice is perfect for soaking up every last drop of that amazing gravy. For a lower-carb option, it’s equally delicious with cauliflower rice or quinoa.

You can also serve it over egg noodles or even creamy mashed potatoes. For a final touch of freshness and color, garnish with a sprinkle of sliced green onions just before serving. A side of steamed broccoli or a crisp salad would round out the meal perfectly.

How to store Crock Pot Pepper Steak

Leftover pepper steak is fantastic for lunch the next day! To store, allow the dish to cool completely to room temperature.

Refrigerator: Transfer the pepper steak to an airtight container. It will keep well in the fridge for up to 4 days.

Freezer: For longer storage, you can freeze it. Place the cooled pepper steak in a freezer-safe container or a heavy-duty freezer bag. It can be frozen for up to 3 months. To serve, thaw it overnight in the refrigerator before reheating.

Reheating: Gently reheat on the stovetop over medium-low heat or in the microwave until warmed through. You may need to add a splash of water or beef broth to loosen the sauce.

Tips to make Crock Pot Pepper Steak

• Don’t Skip the Sear: Searing the beef before adding it to the slow cooker is the most important step for flavor! It creates a savory crust through the Maillard reaction that you just can’t get otherwise.
• Best Cuts of Beef: Sirloin is a great choice as it becomes very tender. However, you can also use flank steak or even a chuck roast cut into strips.
• Easy Slicing: To get perfectly uniform, thin strips of beef, place the sirloin in the freezer for about 20-30 minutes before slicing. It will firm up just enough to make cutting a breeze.
• Customize Your Veggies: Feel free to add other vegetables! Sliced mushrooms, carrots, or even broccoli florets (added in the last 30 minutes of cooking) would be delicious additions.
• For Richer Flavor: If you love deep, savory beef dishes, you might also enjoy this French Onion Beef Stew, which shares that same comforting, slow-cooked goodness.

FAQs About Crock Pot Pepper Steak

Can I prepare this ahead of time?

Absolutely! You can chop all the vegetables and slice the beef the day before. Store them in separate airtight containers in the refrigerator. You can also mix the sauce ingredients ahead of time. This makes assembly on cooking day take just a few minutes.

My sauce didn’t thicken enough. What did I do wrong?

Don’t worry, this is an easy fix! The most common reason is that the cornstarch slurry wasn’t cooked long enough on high heat. Make sure your slow cooker is on HIGH and uncovered for the full 10 minutes. If it’s still not thick enough, you can make another small slurry (1 tablespoon cornstarch to 1 tablespoon cold water) and stir it in, cooking for another 5-10 minutes on HIGH.

Can I use fresh tomatoes instead of canned?

Yes, you can. You’ll need about 2 cups of chopped fresh tomatoes. Using fire-roasted canned tomatoes adds a specific smoky depth, but fresh tomatoes will still create a delicious, slightly brighter-tasting sauce. You may also need to add a splash more water or beef broth to make up for the juices from the can.
