- 1 lb beef tenderloin fillet
- Salt and pepper
- Canola, grapeseed, 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
2 Heat a tablespoon or two of oil in a large pan on high heat. Season the fillet generously with salt and pepper. 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). Remove the fillet from the pan and let cool. Once cooled, brush the fillet on all sides with mustard.
3 Chop the mushrooms and put them into a food processor and purée. Heat a large sauté pan on medium high heat. Scrape the mushroom purée into the pan and let cook down, allowing the mushrooms to release their moisture. When the moisture released by the mushrooms has boiled away, set aside the mushrooms to cool.
4 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 fillet 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 fillet into a tight barrel shape, twisting the ends of the plastic wrap to secure. Refrigerate for 20 minutes.
5 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.
6 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 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.
- Estimate 2 people served per rib
- One standing rib roast, 3 to 7 ribs (estimate serving 2 people per rib), bones cut away from the roast and tied back to the roast with kitchen string
- Freshly ground black pepper
1 Remove the beef roast from the refrigerator 3 hours before you start to cook it. Sprinkle it with salt all over and let it sit, loosely wrapped in the butcher paper. Roasts should be brought close to room temperature before they go into the oven, to ensure more even cooking.
2 Preheat your oven to 500°F (or the highest temp your oven reaches less than 500°F). Pat the roast dry with paper towels (pre-salting should have made the roast release some moisture), and sprinkle the roast all over with salt and pepper.
3 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone.
5 After browning the roast at a 500°F temperature in the oven for 15 minutes, reduce the oven temperature to 325°F. To figure out the total cooking time, allow about 13-15 minutes per pound for rare and 15-17 minutes per pound for medium rare. The actual cooking time will depend on the shape of the roast, how chilled your roast still is when it goes into the oven, and your particular oven. A flatter roast will cook more quickly than a thicker one. There are so many variables involved that affect cooking time, this is why you should use a meat thermometer. A prime rib roast is too expensive to "wing it". Error on the rare side, you can always put the roast back in the oven to cook it more if it is too rare for your taste.
Roast in oven until thermometer registers 115°-120°F for rare or 125°-130°F for medium. (The internal temperature of the roast will continue to rise after you take the roast out of the oven.)
Check the temperature of the roast using a meat thermometer 30 to 45 minutes before you expect the roast to be done. For example, with a 10 pound roast, you would expect 2 1/2 hours of total cooking time (15 minutes at 500° and 2 1/4 hours at 325°). In this case, check after 1 hour 45 minutes of total cooking time, or 1 hour 30 minutes after you lowered the oven temp to 325°. (A benefit of using a remote thermometer is that you don't have to keep checking the roast, you'll be able to see exactly what the temperature is by looking at the thermometer outside of the oven.)
Once the roast has reached the temperature you want, remove it from the oven and place it on a carving board. Cover it with foil and let it rest for 30 minutes before carving. The internal temperature of the roast will continue to rise while the roast is resting.
6 Cut away the strings that were used to hold the roast to the rack of rib bones. Remove the bones (you can save them to make stock for soup if you want.) Then, using a sharp carving knife, slice meat across the grain for serving, making the slices about 1/4-1/2 inch thick.
