Ingredients You’ll Need
The beauty of this Easy Steak Crostini with Horseradish Sauce Recipe is in how straightforward, yet thoughtfully chosen, the ingredients are. Each one plays a key role in creating the perfect balance of flavor, texture, and color that makes these crostini so irresistible.
- Boneless ribeye steak (1″ – 1/2″ thick): The star of the dish, bringing juicy, tender, and flavorful meat that holds up beautifully on crostini.
- Kosher salt: Essential for seasoning and bringing out the natural richness of the steak.
- Boursin cheese (garlic & herb flavor): Adds a creamy, herby depth that complements the boldness of the beef.
- Creamed horseradish: Provides that signature tangy, spicy punch which makes this horseradish sauce unforgettable.
- Baguette (sliced into 1/2"-thick slices): The crunchy, toasted base that offers a perfect contrast to the tender steak and creamy sauce.
- Olive oil: Used for cooking the steak and brushing on baguette slices, yielding a beautiful golden color and subtle richness.
- Balsamic glaze: A little drizzle adds sweetness and acidity that awakens all the flavors.
- Fresh chives: For a fresh, mild onion note and a burst of color to finish the crostini impeccably.
How to Make Easy Steak Crostini with Horseradish Sauce Recipe
Step 1: Season and Cook the Ribeye Steak
Start by generously seasoning your ribeye steak with kosher salt. Heat a skillet over medium-high heat and add a splash of olive oil. When the oil is hot, sear the steak for about 4 minutes on each side to reach a perfect medium-rare. The goal here is a deeply caramelized crust with a juicy interior, which will make your crostini truly stand out.
Step 2: Prepare the Horseradish Sauce
While the steak is cooking, whisk together the Boursin cheese and creamed horseradish in a bowl. Add water little by little to smooth it out until the sauce is creamy and beautifully spreadable. This sauce is the magical ingredient that balances creamy, spicy, and herbaceous notes.
Step 3: Toast the Baguette Slices
Preheat your oven to 400°F (200°C). Brush each baguette slice lightly with olive oil, then arrange them on a baking sheet. Toast for about 5 to 7 minutes or until the edges turn a golden brown. This step ensures your crostini have just the right crunch and hold up well under the toppings.
Step 4: Assemble the Crostini
Thinly slice your perfectly rested ribeye steak. On each toasted baguette, spread a generous spoonful of the horseradish sauce, then top with slices of ribeye. Finish with a delicate drizzle of balsamic glaze for a sweet contrast that ties the whole flavor profile together.
Step 5: Garnish and Serve
Sprinkle freshly chopped chives over the crostini for a pop of color and a hint of fresh bite. Serve them warm to ensure every bite offers the perfect medley of textures and tastes.
How to Serve Easy Steak Crostini with Horseradish Sauce Recipe
Garnishes
Chopped fresh chives are a classic topping that add both vibrancy and a mild onion flavor. You can also consider a few arugula leaves for a peppery contrast or a light sprinkle of cracked black pepper if you like an extra kick.
Side Dishes
These crostini pair beautifully with light, refreshing salads like a simple mixed greens salad with lemon vinaigrette or a crisp cucumber salad. For something heartier, roasted vegetables or grilled asparagus bring wonderful complementary textures and flavors without competing with the crostini.
Creative Ways to Present
Serving these on a rustic wooden board or a slate platter instantly ups the charm factor. Arrange the crostini in neat rows or overlapping circles. For an elegant touch, serve alongside small bowls of additional horseradish sauce and balsamic glaze so guests can customize their bites.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the steak slices and horseradish sauce separately in airtight containers in the refrigerator. Keep toasted baguette slices in a paper bag or loosely wrapped to preserve their crunch for a few hours.
Freezing
Freezing the assembled crostini is not recommended because the bread will become soggy when thawed. However, you can freeze cooked steak slices tightly wrapped for up to two months and thaw them in the fridge before reheating.
Reheating
Reheat steak slices gently in a warm skillet or microwave to avoid drying them out. Refresh the baguette slices in a toaster oven or under the broiler for a minute or two to regain their crispness before assembling the crostini fresh again.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While ribeye is wonderful for its marbling and tenderness, you can substitute with sirloin, filet mignon, or New York strip. Just aim for cuts that are tender and flavorful.
Is there a vegetarian alternative to the steak crostini?
For a vegetarian twist, try substituting grilled portobello mushrooms or roasted eggplant slices in place of the steak. Pair them with the horseradish sauce and other toppings for a similarly delicious experience.
How spicy is the horseradish sauce in this recipe?
The creamed horseradish adds a pleasant, gentle heat—not overwhelming but enough to provide a zingy contrast to the creamy cheese and rich steak. You can adjust the amount to suit your taste.
Can I prepare the horseradish sauce ahead of time?
Yes! The horseradish sauce can be made a few hours in advance and kept refrigerated. Just give it a good stir before spreading it on your crostini to refresh its creamy texture.
What’s the best way to slice the steak for the crostini?
Let the steak rest after cooking, then slice it thinly against the grain. Thin slices ensure tenderness and make the crostini easy to eat in one or two bites.
