Common Mistakes to Avoid
Making Easy Steak Crostini (with Horseradish Sauce) can be simple, but there are a few common mistakes that can lead to less-than-perfect results. Here are some pitfalls to avoid:
-
Skipping the seasoning – Not seasoning the steak properly can result in bland flavor. Always season your ribeye with kosher salt before cooking to enhance its natural taste.
-
Overcooking the steak – Cooking the steak too long will make it tough and dry. Aim for medium-rare, which is about 130°F (54°C) for the perfect tenderness.
-
Using stale bread – Using old or stale baguette slices can ruin the texture of your crostini. Ensure your baguette is fresh and crisp for the best crunch.
-
Neglecting the sauce consistency – If your horseradish sauce is too thick, it won’t spread well on the crostini. Adjust with additional water as needed to achieve a creamy consistency.
-
Skipping garnishes – Forgetting to garnish with chives or balsamic glaze can leave your presentation flat. These final touches add flavor and elevate the dish visually.
