- 1 lb beef tenderloin filet
- Salt and pepper
- Canola oil or olive oil
- 1 lb mushrooms (we used half cremini, half shiitake)
- 4 thin slices ham (Parma ham if you can get it) or prosciutto
- 2 Tbsp yellow mustard (we used Coleman's Original English Mustard)
- 7 ounces puff pastry (needs 3 hours to defrost in refrigerator if using frozen)
- 2 egg yolks, beaten
Flank steak roulade:
- 1/2 pound thin-cut bacon
- 1 1/2 to 1 3/4 pounds flank steak
- Salt and black pepper
- Lemon wedges to serve
- Sear filet on all sides: Season the fillet generously with salt and pepper. Heat a tablespoon or two of oil in a large pan on high heat. Sear the fillet in the pan on all sides until well browned (hint: do not move the fillet until it has had a chance to brown).
- Brush the filet with mustard: Remove the filet from the pan and let cool. Once cooled, brush the fillet on all sides with mustard.
- Prepare the mushroom duxelles: Chop the mushrooms and put them into a food processor and purée. Heat the sauté pan on medium high heat. Transfer the mushroom purée into the pan and cook, allowing the mushrooms to release their moisture. When the moisture released by the mushrooms has boiled away, remove the mushrooms from the pan and set aside to cool.
- Wrap filet in mushroom paste and ham: Roll out a large piece of plastic wrap. Lay out the slices of ham on the plastic wrap so that they overlap. Spread the mushroom mixture over the ham. Place the beef filet in the middle, roll the mushroom and ham over the fillet, using the plastic wrap so that you do this tightly. Wrap up the beef filet into a tight barrel shape, twisting the ends of the plastic wrap to secure. Refrigerate for 20 minutes.
- Preheat oven to 400°F.
- Roll out puff pastry, wrap beef filet: On a lightly floured surface, roll out the puff pastry sheet to a size that will wrap around the beef fillet. Unwrap the fillet from the plastic wrap and place in the middle of the pastry dough. Brush the edges of the pastry with the beaten eggs. Fold the pastry around the fillet, cutting off any excess at the ends (pastry that is more than 2 layers thick will not cook all the way, try to limit the overlap). Place on a small plate, seam side down, and brush beaten egg yolks all over the top. Chill for 5-10 minutes.
- Brush with egg wash and score: Place the pastry-wrapped fillet on a baking pan. Brush the exposed surface again with beaten eggs. Score the top of the pastry with a sharp knife, not going all the way through the pastry. Sprinkle the top with coarse salt.
- Bake in oven: Bake at 400°F for 25-35 minutes. The pastry should be nicely golden when done. To ensure that your roast is medium rare, test with an instant read meat thermometer. Pull out at 125-130°F for medium rare. Remove from oven and let rest for 10 minutes before slicing. Slice in 1-inch thick slices.
