Pro Tips for the Best Steak Bites
- Use the Right Cut – Sirloin, ribeye, or strip steak work best for juicy, tender bites.
- Let the Steak Rest – Before cooking, let the steak sit at room temperature for about 20 minutes to ensure even cooking.
- Don’t Overcrowd the Pan – Cook the steak bites in batches to get a good sear.
- Deglaze the Pan – If you want an extra burst of flavor, add a splash of beef broth or white wine after cooking.
