Common Mistakes to Avoid
When making Easy Steak Crostini (with Horseradish Sauce), it’s easy to overlook a few key details that can affect the final result. Here are some common mistakes to avoid:
- Skipping the seasoning: Failing to season the ribeye steak properly can lead to bland crostini. Always sprinkle kosher salt generously on both sides before cooking.
- Overcooking the steak: Cooking the steak too long can make it tough. Aim for medium-rare, which takes about 3-4 minutes on each side.
- Using stale bread: Stale or old baguette slices won’t provide the right texture. Use fresh baguette slices for that perfect crunch.
- Neglecting the sauce consistency: If your horseradish sauce is too thick, it won’t spread well. Add extra water gradually until you achieve a creamy consistency.
- Forgetting presentation: A crostini that looks good will always taste better. Drizzle with balsamic glaze and sprinkle chives for an appealing finish.
