FAQs – Everything You Need to Know About Slow Cooker Pepper Steak
Can I use frozen beef?
It’s safer to thaw beef before adding it to your slow cooker. Frozen meat may not reach safe internal temperatures quickly enough. For best results, prep the night before and keep it refrigerated.
What’s the best way to thicken the sauce?
If you’re not using cornstarch, you have options. Reduce the sauce by cooking uncovered for the final 30 minutes, or add a small amount of xanthan gum for a keto-friendly fix.
Can I prepare it the night before?
Absolutely. Assemble everything in your slow cooker insert and refrigerate overnight. In the morning, place it in the base, turn it on, and go about your day.
What peppers work best?
You can’t go wrong with red and green bell peppers, but yellow or orange add a different kind of sweetness. Want more complexity? Try poblano or mini sweet peppers.
