Instructions

Prepare the Beef: Pat the beef strips completely dry with paper towels and season lightly with salt and pepper. For the most tender results, cut against the grain into strips about 1/4-inch thick. The drier the beef, the better it will brown and develop flavor during cooking.
Create the Sauce Base: In a small bowl, whisk together soy sauce, brown sugar, cornstarch, ground ginger, black pepper, and red pepper flakes until the cornstarch dissolves completely. This mixture will thicken beautifully during the slow cooking process, creating a glossy coating for the beef and vegetables.
Layer the Crockpot: Place the seasoned beef strips in the bottom of your slow cooker. Add the sliced bell peppers, onions, and minced garlic on top. Pour the drained diced tomatoes over the vegetables, then drizzle the sauce mixture evenly over everything.
Slow Cook to Perfection: Cover and cook on low for 6-8 hours or high for 3-4 hours. The beef should be fork-tender and the peppers should retain some texture but be easily pierced. Avoid lifting the lid during cooking, as this releases valuable heat and moisture.
Final Touches: During the last 30 minutes of cooking, give everything a gentle stir to distribute the thickened sauce. Taste and adjust seasoning if needed – you might want a touch more soy sauce or brown sugar depending on your preference. Garnish with chopped green onions and sesame seeds before serving over cooked rice.

Notes

For best texture, avoid stirring the slow cooker too often during the cooking process, except during the final 30 minutes.
Using low-sodium soy sauce allows better control over the saltiness of the dish.
The cornstarch in the sauce helps to thicken the gravy as it cooks slowly in the crockpot.
You can substitute bell peppers with other sweet peppers or add mushrooms for variation.
Serve immediately with steamed white or brown rice for a complete meal.
Leftovers can be refrigerated for up to 3 days and reheated gently on the stovetop or microwave.
