Step‑by‑Step Instructions for Steak Crostini with Horseradish Sauce
Step 1: Prepare Ribeye
First, let your ribeye steak reach room temperature by sitting for at least 1 hour. Season both sides generously with kosher salt. Heat a cast-iron skillet over medium-high heat and add a drizzle of olive oil. Sear the steak for 8 minutes total, flipping every 2 minutes, until a beautiful brown crust forms. Allow the steak to rest for 10 minutes on a cutting board before slicing it thinly.
Step 2: Make Crostini
Preheat your oven’s broiler to high. Slice the baguette into ½ inch thick pieces for optimal crunch. Arrange the slices on a baking sheet and brush each side lightly with olive oil. Broil for 1 to 1.5 minutes on each side or until they are golden brown and crispy. Keep an eye on them, as they can burn quickly.
Step 3: Prepare Horseradish Sauce
In a small saucepan, combine room-temperature Boursin cheese, a splash of water, and creamed horseradish over medium-low heat. Stir continuously until the mixture melts into a creamy sauce, about 3-4 minutes. Keep stirring until the sauce is smooth and well-combined, adjusting the consistency with more water as needed. Remove from heat and set aside.
Step 4: Assemble Crostini
To create your glorious Steak Crostini with Horseradish Sauce, lay a generous slice of the resting ribeye on each toasted crostini. Top each with a dollop of the creamy horseradish sauce. Finally, drizzle balsamic glaze over the assembled crostini for an extra touch of sweetness and gourmet flair. Garnish with freshly chopped chives to elevate the flavor and presentation.

How to Store and Freeze Steak Crostini
Crostini: Store assembled crostini in an airtight container at room temperature for up to 3 hours, but for best results, assemble just before serving to maintain crispness.
Horseradish Sauce: The creamy horseradish sauce can be made 1-2 days ahead and stored in a sealed jar in the fridge; stir before serving to ensure a smooth consistency.
Cooked Steak: Refrigerate any leftover cooked steak in an airtight container for up to 1 day. Reheat gently in a skillet over low heat or enjoy cold on sandwiches.
Freezing: It’s not recommended to freeze assembled crostini, but you can freeze the cooked ribeye steak for up to 3 months. Thaw in the refrigerator before reheating.

Expert Tips for Steak Crostini

• Control the Heat: When making the horseradish sauce, keep the heat low to avoid burning the ingredients, ensuring a smooth, creamy texture in the sauce.
• Garnish Wisely: Use fresh chives or even a sprinkle of grated Parmesan as a finishing touch to elevate your steak crostini visually and flavorfully.

Steak Crostini with Horseradish Sauce Recipe FAQs
What should I look for when selecting ribeye steak?
Absolutely! When selecting ribeye steak, you want to look for marbling – those white streaks of fat throughout the meat. This fat not only adds juiciness but also enhances the flavor of the steak. Aim for bright red color with no dark spots; a fresh cut will also feel firm to the touch.
How should I store leftover steak crostini?
For the best results, I recommend storing assembled crostini in an airtight container at room temperature for up to 3 hours. However, to maintain optimal crunch, it’s best to assemble them just before serving. If you have leftover cooked steak, refrigerate it in an airtight container for up to 1 day.
Can I freeze the components of the steak crostini?
Yes! You can freeze the cooked ribeye steak for up to 3 months. To do this, let the steak cool completely, then wrap it tightly in plastic wrap followed by foil or place it in a freezer-safe bag. When ready to use, thaw it in the refrigerator overnight before reheating gently on low heat. It’s best not to freeze the assembled crostini, as the texture can suffer.
What if my horseradish sauce is too thick?
Very! If your creamy horseradish sauce turns out too thick, simply add a splash of water and stir over low heat until you reach your desired consistency. I often find that gradually adding water helps to keep the sauce smooth and creamy. If it’s too thin, you can let it simmer for a minute or two until it thickens slightly.
Are there any dietary considerations I should be aware of?
Definitely! If you are making this for guests with dietary restrictions, ensure that you check that the Boursin cheese and baguette you choose are gluten-free, especially if you need to cater to gluten-sensitive individuals. Always label the dish and ingredients for those with allergies, especially to dairy, as the sauce contains cheese.
How long can I prepare horseradish sauce in advance?
You can prepare the horseradish sauce 1-2 days in advance. Store it in a sealed jar in the fridge, and give it a good stir before serving. This allows all those flavorful ingredients to meld beautifully, making the sauce even more delicious!
