1 cup (2 sticks) butter
6 garlic cloves, chopped
4 cups fresh breadcrumbs made from crustless French bread
2 1/2 cups chopped fresh parsley (from 2 to 3 large bunches)
2 2 1/4- to 2 1/2-pound center-cut beef tenderloin roasts
20 to 24 bacon slices (about 1 1/2 pounds)
Canola oil
Melt butter in large pot over medium heat. Add garlic; sauté 2 minutes.
Add breadcrumbs. Sauté until golden brown, about 4 minutes. Remove from
heat; mix in parsley. Season stuffing with salt and pepper. Cool
completely.
Starting at 1 long side, cut each tenderloin lengthwise almost in half,
stopping about 1/2 inch from opposite long side. Open tenderloins like
books. Sprinkle cut sides with salt and pepper. Pack half of stuffing
on 1 side of each tenderloin. Fold plain side over stuffing.
Slightly overlap half of bacon slices on sheet of parchment paper,
forming rectangle equal in length to 1 tenderloin. Place tenderloin at
1 edge, across bacon ends. Using parchment as aid, roll up tenderloin
in bacon. Using kitchen string, secure bacon around tenderloin, tying
at 1 1/2-inch intervals, then tie once lengthwise. Repeat with
remaining bacon and tenderloin. (Can be prepared 1 day ahead. Wrap
tenderloins and refrigerate. Let stand at room temperature 1 hour
before continuing.)
Preheat oven to 400°F. Pour enough oil into large skillet to coat
bottom; heat over high heat. Add 1 tenderloin. Sauté until bacon is
brown, turning often, about 10 minutes. Transfer to rimmed baking
sheet. Repeat with second tenderloin. Roast until thermometer inserted
into center of each registers 130°F to 135°F for medium-rare, about 30
minutes. Transfer to platter. Let stand 15 minutes. Cut off strings.
Cut tenderloins into 1/2-inch-thick slices.
