Prep:20minCook:35min
Make sure the filling and beef are "dry" before assembling. Placing the filling on paper towels and patting the meat to absorb excess liquid will keep the pastry from getting soggy.
When you sear the beef, make sure your pan is VERY hot. You want to sear it quickly - about 30 seconds to 1 minute per side - so it doesn't overcook later in the oven.
Use an egg wash. Yes, you can skip this step, but it will make your pastry shine and look beautiful out of the oven. It will also help the edges stay sealed.
Refrigerate the beef after searing to help cool it down while you make the filling. This will help the beef to keep from overcooking in the oven.
Consider making the dipping sauce(s) in advance to allow time for the flavors to meld.

For the Beef Wellington
Step 2
Preheat over to 400°F.
Step 3
Season the beef cubes with salt and pepper. Preheat a large skillet over high heat. Add the ghee or oil, and sear the beef quickly, for up to a minute, until browned (you don't need to brown it on all sides). Remove the beef from the pan and set it in the refrigerator while you make the filling.
Step 4
Add the finely chopped mushrooms to the pan, also over high heat (this is the temperature which you should almost always cook mushrooms). Once they’ve released their liquid and are starting to brown, reduce the heat to medium and add the minced shallot. You’ll cook this for just a few more minutes until the shallot is soft, stirring frequently.
Step 5
“Drain” the filling on paper towels, remove the beef from the fridge and pat it dry.
Step 6
Line a sheet pan with parchment paper. Roll out two sheets of puff pastry to a large rectangle (add a small amount of flour if it sticks), about 10×14 inches. Cut each piece into 12 even pieces.
Step 7
Place one piece of prosciutto in the center of the puff pastry. Spoon approximately a tablespoon of the filling onto each square, then a piece of beef. Bring up two opposite corners and press them together, then bring up the remaining two corners and press all the seams together. Place them seam-side down on the sheet pan.
Step 8
Brush the wellingtons with the beaten egg yolk. If desired, sprinkle a tiny amount of coarse salt on top of each wellington. Place in the preheated oven and bake until the puff pastry is golden brown, about 20 minutes
