How to Make Crockpot Pepper Steak – Hearty Beef Dinner at Home

1. Start by thinly slicing the flank steak against the grain into strips about 1/2 inch wide for maximum tenderness.
2. In a large skillet over medium-high heat, heat the olive oil. Quickly sear the beef strips until just browned on the outside—about 2 minutes per side. Transfer the beef to the crockpot.
3. Add the sliced bell peppers, onion, and minced garlic to the crockpot, layering them on top of the beef.
4. In a bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, salt, and black pepper. Pour this mixture evenly over the beef and vegetables in the crockpot.
5. Cover and cook on low for 4 hours, or on high for 2.5 hours, until the beef is tender and the peppers are soft but still vibrant.
6. About 15 minutes before serving, mix the cornstarch with water to create a slurry. Stir it into the crockpot to thicken the sauce. Recover and cook for the remaining time.
7. Before serving, taste and adjust seasoning if needed. Garnish with chopped fresh parsley or green onions for a burst of color and freshness.
8. Serve hot over steamed rice, egg noodles, or mashed potatoes for a complete hearty dinner.

Tips for the Best Results

• Slice the beef thinly and against the grain to ensure it stays tender after slow cooking.
• Sear the beef before adding to the crockpot to lock in flavors and improve texture.
• Don’t overcook the peppers to keep some bite and color—they should be soft but not mushy.
• Use low sodium soy sauce to control saltiness and adjust seasoning at the end.
• Thicken the sauce with cornstarch slurry near the end to avoid a thin, watery sauce.

Storage and Reheating

Store any leftover crockpot pepper steak in an airtight container in the refrigerator for up to 4 days. It reheats beautifully and tastes even better the next day as the flavors meld.

For longer storage, freeze leftovers in a freezer-safe container for up to 3 months. Thaw overnight in the fridge and reheat gently on the stovetop or microwave until heated through, stirring occasionally.
