Step 3: Assemble in the Crock Pot
Place the beef strips in the bottom of the crock pot. Layer the sautéed onions and garlic on top, followed by the bell peppers.
Step 4: Make the Sauce
In a small bowl, whisk together the soy sauce, beef broth, oyster sauce, and brown sugar. Pour this mixture over the beef and vegetables. Sprinkle black pepper evenly over the top.
Step 5: Slow Cook
Cover your crock pot with the lid and cook on low for 6–7 hours or on high for 3–4 hours. The slow cooking will tenderize the beef and allow the flavors to meld beautifully.
Pro Tip: Avoid opening the lid frequently, as it can lower the temperature and extend cooking time.
Step 6: Thicken the Sauce
About 30 minutes before serving, mix 1 tablespoon cornstarch with 2 tablespoons cold water to create a slurry. Stir it into the crock pot to thicken the sauce. Allow it to cook for the remaining time to achieve a glossy, rich consistency.
Step 7: Finishing Touch
Once done, drizzle 1 teaspoon sesame oil over the dish for a nutty aroma. Taste and adjust seasoning if necessary.
Step 8: Serve
Scoop the tender beef and vibrant peppers over a bed of steaming white rice, or even enjoy it alongside mashed potatoes or noodles. Garnish with fresh chopped green onions if desired.
Tips for the Perfect Crock Pot Pepper Steak
- Choose the Right Cut: Flank steak or sirloin works best. Avoid tougher cuts that may become stringy even with slow cooking.
- Slice Thinly: Thin strips of beef cook evenly and absorb the sauce better.
- Bell Pepper Variety: Using multiple colors adds visual appeal and a mix of sweet and slightly bitter flavors.
- Avoid Overcooking Vegetables: If you prefer your peppers a bit crisp, add them halfway through cooking instead of at the beginning.
- Make it Ahead: This dish tastes even better the next day as the flavors continue to meld.
