Ingredients
Method
Searing the Beef
- Brush the beef with olive oil.
- Season with salt and pepper.
- Heat a skillet on high heat.
- Add the steaks to the skillet and sear until well browned, about 3 to 4 minutes.
- Flip and continue cooking until the second side is golden brown, about 3 to 4 minutes more.
- Transfer to a rack and cool to room temperature.
Preparing the Mushroom Duxelles
- Use a mini food processor to finely chop the mushrooms into tiny pieces.
- Heat the butter in the skillet over medium-high heat.
- Add the shallot and cook until soft, about 3 to 4 minutes.
- Add the mushrooms and cook until soft, about 5 minutes.
- Add the sherry, cream, and tarragon to the skillet.
- Season with salt and pepper.
- Cook until most of the liquid is absorbed, about 3 to 5 minutes more.
- Turn off the heat and cool this mixture to room temperature.
Assembling the Wellington Bundles
- Roll out the pastry sheets to about ¼-inch thickness.
- Cut into 4 rectangles.
- Place a beef medallion onto each pastry rectangle.
- Brush the edges of the dough with beaten egg.
- Lay a slice of pâté on top of the beef.
- Top with a spoonful of mushroom-tarragon cream sauce. Wrap the pastries up, making sure everything is enclosed.
Sealing and Chilling the Pastry
- Crimp the top ends together to seal.
- (Form the bundles into purses, trimming off the excess pastry.)
- Place each bundle onto a baking sheet coated with vegetable oil spray.
- Cover and chill for at least 1 hour or overnight.
Baking and Serving
- When you are ready to serve, preheat your oven to 425°.
- Brush each package with beaten egg.
- Bake for 10 minutes.
- Reduce the temperature to 375° and continue baking until the pastry is golden, about 20 minutes more.
- Let rest for 10 minutes before serving.
- Serve with red wine sauce (see recipe).
Boiling and Mashing the Potatoes
- Add the potatoes to a pot with salted boiling water.
- Cook until the potatoes are very soft, about 8 to 10 minutes.
- Use a colander to drain the potatoes.
- Place 3 tablespoons room-temperature butter and the milk into a large bowl.
- Use a potato ricer to mash up the potatoes.
- Stir into a smooth puree.
Preparing the Baking Dishes
- Preheat your oven to 400°.
Whipping and Folding the Cream
- Use an electric mixer to whip the cream into soft peaks.
- Place about ⅓ of the whipped cream into the center of the potatoes.
- Gently stir the cream into the potatoes.
- The potatoes will be soft and light.
- Scrape the remaining whipped cream into the bowl with the potatoes.
- Gently fold this cream into the potatoes.
Baking the Potatoes
- You don’t need to overwork the potatoes. You want these to be light and airy.
- Divide 1 tablespoon butter into four individual baking dishes. Place these into a larger baking dish. Place in the oven and let the butter melt on the bottom of each one, about 2 to 3 minutes. (If you don’t want to serve in individual containers, simply melt the butter in one large baking dish.)
- Remove the hot dishes (use a potholder).
- Spoon in the potatoes.
- Sprinkle each dish with Parmesan cheese.
- Bake until the potatoes are warmed through and the tops begin to turn golden brown on the edges, about 20 to 25 minutes.
