  • 3-4 pounds beef tenderloin, about 10-inches long, from the thick-end (butt beef tenderloin)

Step 5 –Place the whole tenderloin, toothpick-side down, in the skillet and cook until the bacon is browned on all sides, about 10 minutes.

Step 6 –Place the beef tenderloin in a large slow cooker, pouring the drippings over the top.

Step 7 –Place the sliced onion, the garlic cloves, and the rosemary sprigs around the beef.

Step 8 –Cover and cook the beef until it reaches 130 degrees F internally, about 2-4 hours.

Step 9 –Once the temperature of the meat reaches 100 degrees F, mix the flour and the sugar together in a medium bowl.

Step 10 –Whisk the vinegar and the mustard into the sugar mixture until there are no clumps.

Step 11 –Whisk in the beef stock.

Step 12 –Pour the beef stock mixture around the tenderloin, and cover to continue cooking so the tenderloin can reach 130 degrees F.

Step 13 –Once the tenderloin is 130 degrees F internally, transfer it from the slow cooker and cover it with foil.

Step 14 –Let the tenderloin rest for at least 10 minutes so the temperature can reach 135 degrees F internally.

Step 15 –Simmer the balsamic glaze until thick.

Step 16 –Remove the toothpicks and slice the tenderloin into thin rounds.

Step 17 –Serve with the balsamic glaze.
