Slice baguette into 1/4″ slices and arrange the baguette slices on a baking sheet. It should make about 20 slices. Lightly brush both sides with olive oil and sprinkle with salt.
Bake until lightly golden, approximately 5 minutes.
To prepare beef, pat filet dry and season generously with salt, black pepper, and garlic powder. Heat a cast iron until very hot (medium-high heat) and add a tablespoon of olive oil to the pan.
Add your Beef Tenderloin and sear for 4 to 5 minutes on each side. Cook to your desired doneness by checking with a meat thermometer.
Prepare horseradish cream by whisking together horseradish, sour cream, Dijon mustard, Worcestershire sauce, salt and pepper until creamy and smooth.
Using a sharp knife, thinly slice beef tenderloin. Spread horseradish cream on top of each baguette slice and top with a slice of beef.
Garnish with a small dollop of horseradish cream, a trio of pomegranate arils and fresh herbs like parsley and chives.
