Step-by-Step Preparation (Detailed)
Step 1: Slice the Beef
Thinly slice the beef against the grain. This ensures tender, easy-to-chew pieces after cooking.
Pro Tip: Slightly freeze the beef for 20 minutes to make slicing easier.
Step 2: Prepare the Sauce
In a bowl, whisk together:
- Beef broth
- Soy sauce
- Cornstarch
- Brown sugar
- Ginger
- Black pepper
Mix until smooth and lump-free.
Step 3: Layer Ingredients
Place the sliced beef into the crockpot. Add onions, garlic, and bell peppers on top.
Step 4: Add the Sauce
Pour the sauce evenly over everything. Do not stir yet—this helps flavors develop gradually.
Step 5: Slow Cook
- Low setting: 6–7 hours
- High setting: 3–4 hours
The beef should become tender and infused with flavor.
Step 6: Stir & Thicken
About 30 minutes before serving, stir everything together. The sauce will thicken into a glossy coating.
Texture Cue: Sauce should cling to the beef, not be watery.
Step 7: Final Touch
Add sesame oil (optional) and adjust seasoning if needed. Let it sit for 5–10 minutes before serving.
