# Steps:
01 -
Heat grill to 450°F. Season filet mignon with steak seasoning. Grill for 4-5 minutes per side until internal temperature reaches 125°F for medium rare. Remove from heat and let rest for 10 minutes before thinly slicing against the grain.

In a medium bowl, whisk together sour cream, prepared horseradish, dijon mustard, champagne vinegar, worcestershire sauce, and chopped chives. Season with salt and pepper to taste. Refrigerate until ready to use.

Slice baguette into 24 even pieces. Combine melted butter, olive oil, and minced garlic in a small bowl. Brush mixture onto both sides of each baguette slice. Arrange on a baking sheet and bake at 375°F for 5 minutes per side until golden and crisp.
04 -
Heat a tablespoon of oil and butter in a skillet over medium-low heat. Add diced onions and cook for 15-20 minutes, stirring occasionally, until soft and golden brown. Add sugar and continue cooking for 3-4 more minutes until deeply caramelized.

Spread each toasted baguette slice with a layer of horseradish sauce. Top with a slice of steak and a spoonful of caramelized onions. Garnish with fresh chives and a light drizzle of balsamic glaze just before serving.
