Roasted Beef Tenderloin with Caramelized Onions

Instructions

1. 1

   With the rack in the middle position, preheat the oven to 200 °C (400 °F).

2. 2

   In a bowl, combine the spices. Brush the roast with the mustard, then coat with spices.

3. 3

   In a large ovenproof skillet, brown the roast in half the butter. Season with salt and pepper. Set aside on a plate.

4. 4

   In the same skillet, brown the onions over high heat in the remaining butter. Place the roast over the onions and bake for about 45 minutes or until a meat thermometer inserted into the centre of the roast reads 48 °C (118 °F) for medium rare doneness. Count about 15 minutes per 454 g/1 lb of meat. Cover with foil. Let stand for 10 minutes at room temperature.
