Brush baguette slices with olive oil and bake for 8-10 minutes until golden and crispy.
Season beef with salt and pepper.
Heat butter in a skillet over medium-high heat. Sear the beef for 2-3 minutes per side for medium-rare (adjust as needed).
Let the beef rest for 5 minutes, then slice thinly.
In a small bowl, mix blue cheese, sour cream, Dijon mustard, and Worcestershire sauce until smooth.
Spread a layer of blue cheese mixture on each toasted baguette slice. Top with sliced beef. Garnish with chopped chives and drizzle with balsamic glaze if using.
Serve & Enjoy
Notes
For extra flavor, rub the baguette slices with a garlic clove before toasting.
You can substitute beef tenderloin with roast beef slices for a quicker version.
Blue cheese can be swapped for gorgonzola if you prefer a milder taste.
Serve immediately for the best texture and flavor.
