Preparation Time: 45 mins
Cooking Time: 30 mins
- 2 lbs centre-cut beef tenderloin trimmed of fat and lining
- Kosher salt
- fresh ground black pepper
- 2 tbsp extra virgin olive oil
- 1 tbsp fresh ground horseradish
- 2 tbsp mustard English Mustard, Dijon, or Spicy Brown
- 1/2 lb prosciutto ham thin sliced (16 slices)
- 2 frozen puff pastry sheets thawed
- flour for dusting
- 1 egg
- 1 tsp milk
- Coarse sea salt Maldon or Fleur de Sel
- 5-pound mushrooms portabella, cremini, white button, assorted mix, cleaned, trimmed and roughly chopped
- 4 garlic cloves minced
- 2 tsp fresh thyme leaves
- Fresh ground black pepper
Caramelized Onions and Garlic
- 1 large sweet onion medium dice
- 1 garlic clove minced
- 1 tbsp extra-virgin olive oil
- Fresh ground black pepper
To make mushroom duxelles
- Clean mushrooms to remove any dirt. Trim the stems and roughly chop. Mushrooms have high water content and tend to absorb water when soaked. I prefer to brush off the dirt without using water to keep as dry as possible. If there is a lot of dirt, then do a quick rinse in cold water.
- Add mushrooms, garlic and thyme to a large food processor and pulse to get a chopped mixture with spreadable consistency but with a bit of chunkiness (think of chunky peanut butter). The classic recipe calls for the mushrooms to be processed until smooth like hummus but I liked to keep a bit of texture. You may need to do this part in batches depending on the size of your food processor.
- In a non-stick skillet over medium heat, add mushroom mixture to the dry pan. Season with salt and pepper (I also like to use my favourite garlic salt). Spread the mixture evenly over the surface and cook on medium-low heat for about 10 minutes or until the moisture in the paste has reduced and the mixture has the consistency of a spreadable pâté. Remove from heat and let cool. It is very important that this mixture is as dry as possible to avoid the pastry from getting soggy during baking.
- When you have finished cooking the mushroom duxelles, remove the mixture to a plate and set aside to cool completely.
To make caramelized onions
- In the same skillet, add olive oil and saute sliced onions on medium-low heat until browned and soft. Season with salt and pepper. You want this mixture to become as dry as possible so cook until the pan is dry. Remove from heat, place in a bowl and refrigerate until ready to use. You may need to squeeze out any remaining liquid before you add to your wellington.
To make beef
- Pat filet mignon dry with paper towels and season generously with Kosher salt and black pepper.
- Heat a clean non-stick skillet on high heat and add olive oil. When the oil begins to smoke, add the tenderloin and brown from 1 to 2 minutes on each side, including ends for no more than 8 minutes. You want to sear the outside but leave the inside raw. Remove from heat and place on a plate.
- Combine mustard and horseradish in a small bowl.
- Brush filet with a mixture of mustard and horseradish on all sides. As filet cools it absorbs the mustard. If you prefer you can omit the horseradish and only use mustard or vice versa. I like the combination of the two flavours as the horseradish adds a bit of heat, the mustard adds a bit of tanginess and combined they will make the filet taste amazing.
- On a cutting board, lay out a long piece of plastic wrap. It should be wider than the piece of beef and long enough to allow you to wrap it around the beef completely. If needed use two sheets overlapping.
- In the middle of the wrap, layer prosciutto slices wider than the piece of beef. Be sure to overlap and shingle them so they don’t separate. Lay them vertically in front of you. Season with fresh ground pepper.
- Spread mushroom duxelles in a thin even layer over the prosciutto using the back of a spoon.
- Spread the caramelized onions over the duxelles in an even layer.
- Place filet horizontally on top, in the centre. Gently wrap the prosciutto around the beef using the plastic wrap to roll the mixture away from you. Wrap tightly and twist ends to get it cylinder tight. The tighter the beef is wrapped the better it will hold its shape and cook evenly.
- Place the beef in the refrigerator for at least 15 minutes to firm up.
- Layout a clean, long piece of plastic wrap. It should be the same length as previously used so that it is long enough to allow you to wrap beef completely.
- Dust board or countertop lightly with flour. Spread puff pastry on board and, using a rolling pin, roll it into a rectangle at least 4-inches wider than the beef roll on its shorter side. It should be large enough to wrap the beef, leaving some excess on the sides. You may need to put together two sheets. Use egg wash to bind the seams.
- Remove the beef from the refrigerator. Remove the plastic wrap from the beef wrapped in prosciutto and place on one end of the puff pastry.
- In a bowl, beat egg and milk to create an egg wash.
- Brush puff pastry around beef roll with beaten egg wash. Carefully wrap the beef in the puff pastry using the plastic wrap to pull tightly. The long ends of the sheet should meet and you can trim off any excess. Tuck or pinch the short ends closed so the beef is perfectly encased. Use the plastic wrap to tightly seal the puff pastry. Return to the refrigerator for at least 5 minutes to firm up again or leave in overnight.
- To Bake the Beef Wellington
- Adjust oven rack to centre position and preheat oven to 425°F.
- Place a sheet of aluminium foil on a baking sheet. Remove Wellington from the refrigerator, remove the plastic wrap, and lay the Wellington seam-side down on the baking sheet.
- Brush the top of the puff pastry with egg wash.
- Using the back of a knife, score a leaf pattern into the pastry but be careful not to cut through the pastry. You can also cut out shapes with the leftover pastry and lay those on top to decorate. Brush with additional egg wash after you decorate.
- Sprinkle liberally with coarse sea salt. I used Maldon.
- Bake for approximately 25 to 30 minutes, or until pastry is golden brown and the internal temperature of the beef reaches 110º F for rare, 120º F for medium-rare. The beef will continue to cook as it cools. Check at 30 minutes, if the beef is not at your desired temperature, leave in for longer but check it every few minutes. You do not want to overcook it. The use of a digital instant-read thermometer is very important.
- Remove from the oven and let rest for at least 10-15 minutes before slicing.
- If Wellington is browning too quickly and it has not achieved your desired temperature, cover it with a piece of foil to stop it from browning further.
- To serve, use a thin metal spatula to loosen Wellington from foil, then carefully transfer to a carving board. Slice off the ends with a sharp knife. Carve Wellington into thick slices, sprinkle cut surfaces with coarse salt, and serve.
