🫑 Slow Cooker Pepper Steak

Introduction

Slow Cooker Pepper Steak is one of those comforting, hearty meals that makes dinner feel effortless. Tender strips of beef slowly simmer with colorful bell peppers and sweet onions, creating a savory, flavorful dish that is perfect for busy weeknights or relaxed family dinners.

The slow cooker does most of the work, allowing the beef to become tender while the peppers and onions soften and add their natural sweetness. Serve it over fluffy white rice, brown rice, mashed potatoes, or egg noodles for a satisfying meal everyone will love.

Ingredients

For the Pepper Steak

1½ pounds beef steak, thinly sliced
1 green bell pepper, sliced
1 red bell pepper, sliced
1 yellow bell pepper, sliced
1 medium onion, sliced

For the Sauce

1½ cups beef broth
½ cup low-sodium soy sauce
2 tablespoons Worcestershire sauce
2 tablespoons tomato paste
2 cloves garlic, minced
1 tablespoon brown sugar
1 teaspoon smoked paprika
½ teaspoon black pepper
½ teaspoon onion powder
¼ teaspoon crushed red pepper flakes, optional
2 tablespoons cornstarch
3 tablespoons cold water

For Serving

Cooked rice, mashed potatoes, or egg noodles
Fresh parsley or sliced green onions, optional

Instructions

1. Prepare the Beef

Trim any excess fat from the steak and slice it thinly against the grain. Thin slices cook more evenly and make the finished beef easier to eat.

For extra flavor, season the beef lightly with black pepper and a little onion powder.

2. Prepare the Vegetables

Wash and slice the green, red, and yellow bell peppers into strips. Slice the onion into thin wedges or strips.

Keeping the peppers in reasonably large pieces helps them maintain some texture during slow cooking.

3. Build the Sauce

In a bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, tomato paste, minced garlic, brown sugar, smoked paprika, black pepper, and onion powder.

Taste the sauce before adding it to the slow cooker. Because soy sauce already contains salt, additional salt may not be necessary.

4. Layer Everything in the Slow Cooker

Place the sliced beef in the bottom of the slow cooker.

Add the sliced onion and bell peppers over the beef.

Pour the prepared sauce evenly over everything.

Give the ingredients a gentle stir so the sauce coats the beef and vegetables.

5. Slow Cook

Cover and cook on:

LOW for 5–6 hours

HIGH for 2½–3½ hours

Cooking times can vary depending on the thickness of the beef and the slow cooker.

Avoid repeatedly lifting the lid because releasing the heat can increase cooking time.

6. Thicken the Sauce

About 20–30 minutes before serving, whisk together the cornstarch and cold water to make a smooth slurry.

Stir the slurry into the slow cooker.

Cover and continue cooking until the sauce becomes glossy and thick enough to coat the beef and vegetables.

7. Taste and Finish

Taste the pepper steak and adjust the seasoning if needed.

For a little extra brightness, garnish with fresh parsley or sliced green onions.

Cooking Method

The slow-cooker method is especially convenient because the beef and vegetables gradually cook together in a savory sauce.

For an even richer flavor, you can quickly sear the sliced beef in a hot skillet with a little oil before placing it in the slow cooker. This step is optional, but browning the meat can add extra depth and a more roasted flavor.

Do not overcrowd the skillet if you choose to sear the beef. Work in batches so the meat browns instead of steaming.

History

Pepper steak is part of a broad American tradition of preparing tender pieces of beef with peppers, onions, and a savory sauce. Versions of the dish became especially popular as home cooks embraced quick stir-fry techniques and flavorful combinations of beef and vegetables.

The slow-cooker version takes the same basic flavor idea and turns it into an easy comfort-food dinner. Instead of quickly cooking the ingredients in a skillet, the slow cooker gives the beef time to absorb the savory sauce while the peppers and onions become tender.

Formation of the Dish

The beauty of this recipe comes from the way the ingredients work together.

The beef provides a hearty, savory base.

The green, red, and yellow peppers bring color, sweetness, and a little freshness.

The onion adds natural sweetness and depth as it cooks.

The beef broth, soy sauce, and Worcestershire sauce create the rich savory foundation.

The tomato paste adds body and a deeper flavor to the sauce.

The brown sugar balances the salty and savory ingredients.

Finally, the cornstarch slurry transforms the cooking liquid into a thick, silky sauce that clings beautifully to the beef and vegetables.

Serving Ideas

Serve this Slow Cooker Pepper Steak over:

🍚 Steamed white rice
🍚 Brown rice
🥔 Creamy mashed potatoes
🍜 Egg noodles
🍚 Cauliflower rice
🥖 Crusty bread for soaking up the sauce

Tips for Tender Pepper Steak

Slice against the grain: This helps make the beef easier to chew.

Don’t overcook the peppers: If you prefer firmer peppers, add them during the final 1½–2 hours of cooking instead of at the beginning.

Use low-sodium soy sauce: It gives you more control over the saltiness.

Sear the beef first: This optional step adds a deeper browned flavor.

Thicken at the end: Adding the cornstarch slurry near the end prevents the sauce from becoming overly thick during the long cooking process.

Make-Ahead & Storage

Leftover pepper steak can be refrigerated in an airtight container for up to 3–4 days.

Reheat gently in the microwave or in a saucepan over medium-low heat. Add a small splash of beef broth or water if the sauce has become too thick.

The finished dish can also be frozen in suitable airtight containers. Thaw in the refrigerator before reheating.
