Pepper Steak in Crock Pot Recipe

Pepper steak may sound like a dish straight from a steakhouse menu, but in home kitchens across the world, it takes on an entirely different — and equally delicious — form. When made in a crock pot, pepper steak transforms into something tender, savory, and deeply satisfying. The flavors meld over hours, the beef becomes fork-tender, and the vibrant bell peppers lend both color and a subtle sweetness that balances the dish beautifully.

This is comfort food with character.

The beauty of crock pot pepper steak lies in its simplicity and adaptability. A few humble ingredients — beef strips, bell peppers, onions, soy sauce, garlic, and a few pantry staples — come together with minimal effort and yield maximum flavor. Whether you’re feeding a busy family on a weeknight or preparing a no-fuss meal for a lazy Sunday, this slow cooker version of pepper steak is a dish that delivers every time.

While the traditional stovetop version is quick and bold, slow cooking gives this recipe a depth and texture that’s hard to replicate on the stovetop. It allows the beef to marinate and break down slowly, absorbing the savory sauce until every bite is infused with rich, umami flavor. Meanwhile, the peppers soften just enough to be tender, but still maintain their identity and color — a welcome contrast to the richness of the beef.

But pepper steak isn’t just about convenience — it has culinary roots that stretch back decades. It draws influence from Chinese-American cuisine, with its use of soy sauce, garlic, and stir-fry style ingredients, but it has also found a place in Southern, Midwestern, and even Caribbean kitchens, where families have added their own twists. Some add tomatoes for acidity, others incorporate ginger or oyster sauce, and still others spice it up with hot peppers or Cajun seasonings. That versatility is part of what makes this dish so enduring.

In this guide, we’ll take a deep dive into what makes pepper steak in the crock pot such a rewarding dish to master. You’ll learn:

• How to select the best cuts of beef for slow cooking

So plug in your slow cooker, slice up those peppers, and let’s begin a flavorful journey into one of the most comforting dishes to ever come out of a crock pot.

Step-by-Step Instructions: How to Make Pepper Steak in the Crock Pot

Making pepper steak in a crock pot is all about layering flavors and timing your ingredients carefully to achieve tender beef and perfectly cooked peppers. Below is a detailed breakdown of the entire cooking process.

Step 1: Select and Prepare Your Beef

The cut of beef you use greatly impacts the final texture and flavor.

• Recommended Cuts: Flank steak, sirloin tip, chuck roast, or round steak. These cuts become tender when cooked low and slow.

• Slicing: For best results, slice the beef thinly against the grain into strips about ¼ inch thick and 2–3 inches long. Cutting against the grain shortens the muscle fibers, making the beef easier to chew after slow cooking.

• Tip: To slice more easily, partially freeze the beef for 20–30 minutes before cutting.

Step 2: Prepare the Vegetables

• Bell Peppers: Use a mix of colors (red, green, yellow, orange) for a vibrant, balanced dish. Slice them into thin strips, about the same size as the beef strips.

• Onion: Slice into thin wedges or strips.

• Garlic: Mince finely.

• Optional Vegetables: Some variations add sliced mushrooms or celery for extra texture.

Step 3: Make the Sauce Base

The sauce brings the dish together with a perfect balance of salty, sweet, and umami.

• Key Ingredients:

  • Soy sauce for saltiness and depth

  • Beef broth or stock for richness

  • Brown sugar or honey for sweetness

  • Worcestershire sauce for complexity

  • Cornstarch slurry (cornstarch mixed with cold water) to thicken the sauce later

• Combine: Whisk soy sauce, beef broth, brown sugar, Worcestershire sauce, and garlic together in a bowl.

Step 4: Brown the Beef (Optional but Recommended)

While the slow cooker can cook raw beef well, browning adds flavor and better texture.

• Heat a large skillet over medium-high heat with a tablespoon of oil.

• Quickly sear the beef strips in batches, about 1–2 minutes per side, until browned but not cooked through.

• Remove the beef and set aside.

Step 5: Layer Ingredients in the Crock Pot

• Add the sliced onions to the bottom of the crock pot.

• Place the browned (or raw) beef strips over the onions.

• Add the sliced bell peppers on top.

• Pour the sauce mixture evenly over all ingredients.

Step 6: Cook on Low for 6–8 Hours or High for 3–4 Hours

• Cover and cook until the beef is fork-tender and the peppers are soft but still retain some bite.

• Avoid overcooking the peppers if possible to maintain color and texture.

Step 7: Thicken the Sauce

• About 30 minutes before serving, mix cornstarch with cold water to create a slurry.

• Stir the slurry into the crock pot and switch to high heat.

• Cook uncovered for the remaining time to thicken the sauce.

• Stir occasionally to prevent sticking.

Step 8: Taste and Adjust Seasoning

• Before serving, taste the sauce and adjust seasoning if needed:

  • More soy sauce for saltiness

  • More sugar or honey if you want sweetness

  • A splash of vinegar or lemon juice for brightness

Step 9: Serve

• Serve hot over steamed white rice, brown rice, or noodles.

• Garnish with chopped green onions or fresh cilantro for added freshness.

• Optional: Add a sprinkle of crushed red pepper flakes if you like heat.
