Common Mistakes to Avoid
Slow cooking can be simple, but small errors can affect your Pepper Steak in a Crock Pot. Here are common mistakes to avoid:
- Skipping the seasoning: Not seasoning the beef before cooking can lead to bland flavor. Always season your meat with salt and pepper for a better taste.
- Overcrowding the slow cooker: Filling the crock pot too much can prevent even cooking. Ensure there’s enough space for heat circulation by following ingredient amounts closely.
- Not thickening the sauce properly: If you forget to add the cornstarch mixture near the end of cooking, your sauce may be too thin. Remember to mix cornstarch with cold water and stir it in during the last 30 minutes.
- Using frozen beef: Cooking beef straight from the freezer can lead to uneven cooking. Always thaw your beef beforehand for consistent results.
- Neglecting the vegetables’ placement: Placing vegetables on top of the meat helps them cook evenly. Always layer bell peppers and onions over your seasoned beef.
- Ignoring cook times: Cooking on HIGH instead of LOW can toughen the meat. Stick to recommended cook times for tender, flavorful results.
