Common Mistakes to Avoid
To make your Easy Steak Crostini (with Horseradish Sauce) a hit, avoid these common pitfalls.

- Overcooking the steak: Cooking the steak for too long can make it tough. Aim for a medium-rare finish for the best taste and texture.
- Ignoring the bread quality: Using stale or low-quality bread can ruin your crostini. Select a fresh baguette for a perfect crunch.
- Forgetting to let the steak rest: Cutting into the steak too soon allows juices to escape, leading to a dry result. Let it rest for at least 5 minutes.
- Not adjusting horseradish sauce thickness: If your sauce is too thick, it won’t spread well. Add more water gradually until you reach your desired consistency.
