Ingredients
Scale
Protein:
- 8 ounces (226 grams) filet mignon
- 2 tablespoons steak seasoning
Crostini Base and Herbs:
- 1 baguette, day-old
- 2 tablespoons butter
- 1/4 cup olive oil
- 1 garlic clove
- 1 onion, diced
- 1/2 tablespoon fresh chives
Sauce and Seasoning:
- 1 cup sour cream
- 1/4 cup prepared horseradish
- 1 1/2 tablespoons dijon mustard
- 1 teaspoon champagne vinegar
- 1 teaspoon worcestershire sauce
- 1/4 teaspoon sugar
- Balsamic glaze for serving
Instructions
- Preheat grill to searing temperature of 450F. Season steak generously with preferred seasoning blend.
- Grill steak for 4-5 minutes on each side, targeting internal temperature of 125F for medium rare doneness.
- Remove steak from grill and allow to rest for 10 minutes, allowing juices to redistribute throughout meat.
- While steak rests, prepare horseradish cream sauce by whisking sour cream, horseradish, dijon mustard, vinegar, worcestershire sauce, chopped chives, salt, and pepper until smooth and well combined.
- Slice baguette diagonally into thin, uniform pieces for crostini base.
- Create garlic butter mixture by combining melted butter, olive oil, and minced garlic.
- Brush each baguette slice with garlic butter mixture and arrange on baking sheet.
- Toast bread in preheated oven at 375F for 5 minutes per side until edges are crisp and golden.
- In separate pan, caramelize onions over medium-low heat using combination of oil and butter for 15-20 minutes.
- Sprinkle small amount of sugar over onions during final 3-4 minutes of cooking to enhance browning and sweetness.
- Slice rested steak against grain into thin, elegant strips.
- Assemble crostini by spreading horseradish sauce on toasted bread, layering with steak slices and caramelized onions.
- Finish by garnishing with fresh chopped chives and drizzle of balsamic reduction.
Notes
- Choose a well-marbled cut like ribeye or sirloin for maximum flavor and tenderness when grilling.
- Slice steak against the grain to ensure each bite remains juicy and easy to chew.
- Allow steak to reach room temperature before grilling to promote even cooking and better sear.
- Use fresh horseradish for a more vibrant and zesty sauce that elevates the entire dish.
- Caramelize onions slowly to develop deep, sweet complexity that complements the rich steak.
- Try different bread types like sourdough or ciabatta for varied texture and taste.
- Make extra sauce and store in refrigerator for up to 3 days as a versatile condiment.
- For gluten-free option, replace baguette with gluten-free bread or roasted sweet potato slices.
